A supply of lubricating oil must be fed to the crankcase to supply the crankshaft bearings. Since the crankcase is also used to supply air to the engine, the engine's lubricating oil is carried into the cylinder with the air charge, burnt during combustion and carried out of the exhaust. The oil carried from the crankcase to the cylinder is used to lubricate the piston. This means that a two-stroke hot-bulb engine will gradually burn its supply of lubricating oil, a design known as a "total-loss" lubricating system.

In cooperation with ASTM International and SAE International, the NLGI has developed the categorisation of lubricating greases specified in standard “standard classification and specification for automotive service greases”, reproduced in standard “automotive lubricating greases”. The NLGI retains jurisdiction over the designation and definition of the categories, which it publishes in its “chassis and wheel bearing service classification system”. The NLGI has also created a symbol, the NLGI Certification Mark, which can be used on containers of greases to advertise their category. The measure of the consistency of a lubricating grease is commonly expressed by its NLGI consistency number, defined by the NLGI in the “standard classification of lubricating grease”. The NLGI consistency number is used in several standards: , and “lubricants, industrial oils and related products (class L) — classification — part 9: family X (greases)”.

Graphite and graphite powder are valued in industrial applications for their self-lubricating and dry lubricating properties. There is a common belief that graphite's lubricating properties are solely due to the loose interlamellar coupling between sheets in the structure. However, it has been shown that in a vacuum environment (such as in technologies for use in space), graphite degrades as a lubricant, due to the hypoxic conditions. This observation led to the hypothesis that the lubrication is due to the presence of fluids between the layers, such as air and water, which are naturally adsorbed from the environment.

The NLGI consistency number (sometimes called “NLGI grade”) expresses a measure of the relative hardness of a grease used for lubrication, as specified by the standard classification of lubricating grease established by the National Lubricating Grease Institute (NLGI). Reproduced in standards (“standard classification and specification of automotive service greases”) and (“automotive lubricating greases”), NLGI's classification is widely used. The NLGI consistency number is also a component of the code specified in standard “lubricants, industrial oils and related products (class L) — classification — part 9: family X (greases)”. The NLGI consistency number alone is not sufficient for specifying the grease required by a particular application.

A different approach was suggested by Prof. J. Aizenberg from Harvard University, who suggested to use Slippery Liquid-Infused Porous Surfaces (SLIPS), a porous material inspired by the carnivorous pitcher plant and filled with a lubricating liquid immiscible with both water and oil. SLIPS possess self-healing and self-lubricating properties as well as icephobicity and were successfully used for many purposes.

The condensate may wash the lubricating oil from the cylinder walls, travel past the piston rings and collect in the oil pan, thus increasing wear and also diluting the lubricating oil. Since the less volatile components of the fuel will have the greatest tendency to condense, the degree of crankcase-oil dilution is directly related to the end volatility temperatures of the mixture.

Anti- friction (AF) coatings are "lubricating paints" consisting of fine particles of lubricating pigments, such as molydisulfide, PTFE or graphite, blended with a binder. After application and proper curing, these "slippery" or dry lubricants bond to the metal surface and form a dark gray solid film. Many dry film lubricants contain special rust inhibitors which offer exceptional corrosion protection. Most long-wearing films are of the bonded type but are still restricted to applications where sliding distances are not too long.

In a reciprocating engine, the cylinder is the space in which a piston travels. The inner surface of the cylinder is formed from either a thin metallic liner (also called "sleeve") or a surface coating applied to the engine block. A piston is seated inside each cylinder by several metal piston rings, which also provide seals for compression and the lubricating oil. The piston rings do not actually touch the cylinder walls, instead they ride on a thin layer of lubricating oil.

Self-lubricating composites: Solid lubricants such as PTFE, graphite, MoS2 and some other anti-friction and anti-wear additives are often compounded in polymers and all kind of sintered materials. MoS2, for example, is compounded in materials for sleeve bearings, elastomer O-rings, carbon brushes, etc. Solid lubricants are compounded in plastics to form a "self-lubricating" or "internally lubricated" thermoplastic composite. For example, PTFE particles compounded in the plastic form a PTFE film over the mating surface, resulting in a reduction of friction and wear.

Two-stroke engines, and most model engines, have a total-loss lubrication system. Lubricating oil is mixed with the fuel, either manually beforehand (the petroil method), or automatically via an oil pump. Prior to being burned in the combustion chamber, this air/fuel/oil mixture passes through the engine's crankcase, lubricating the moving parts as it does so. In order to reduce exhaust smoke, the Kawasaki H2 2-stroke triple motorcycle had a scavenge pump with a spring-loaded ball-valve under each crankcase to return surplus oil to the tank for reuse.

Polyisobutylene can be reacted with maleic anhydride to make polyisobutenylsuccinic anhydride (PIBSA), which can then be converted into polyisobutenylsuccinimides (PIBSI) by reacting it with various ethyleneamines. When used as an additive in lubricating oils and motor fuels, they can have a substantial effect on the properties of the oil or fuel. Polyisobutylene added in small amounts to the lubricating oils used in machining results in a significant reduction in the generation of oil mist and thus reduces the operator's inhalation of oil mist. It is also used to clean up waterborne oil spills as part of the commercial product Elastol.

Some ionic liquids have been shown to reduce friction and wear in basic tribological testing, and their polar nature makes them candidate lubricants for tribotronic applications. While the comparatively high cost of ionic liquids currently prevents their use as neat lubricants, adding ionic liquids in concentrations as low as 0.5 wt% may significantly alter the lubricating performance of conventional base oils. Thus, the current focus of research is on using ionic liquids as additives to lubricating oils, often with the motivation to replace widely used, ecologically harmful lubricant additives. However, the claimed ecological advantage of ionic liquids has been questioned repeatedly and is yet to be demonstrated from a lifecycle perspective.

Not all handloaders resize cast lead bullets, although all handloaders do lubricate cast lead bullets. An option to using a lubricating press is simply to coat the bullets with bullet lube, which can be done either with a spray, in a tumbler, in a plastic bowel with a liquid lube, in a tray with melted bullet lube, or even with a manual lubricating process. Slugs for shotgun shells are also commonly cast from pure lead by handloaders, for subsequent reloading into shotgun shells. Although roll crimps of shotgun hull cases are commonly used for handloading these cast lead slugs, in place of the fold crimps that are used when reloading shot into shotgun shells, some published recipes specifically do include fold crimps.

The viscosity index (VI) is an arbitrary, unit-less measure of a fluid's change in viscosity relative to temperature change. It is mostly used to characterize the viscosity-temperature behavior of lubricating oils. The lower the VI, the more the viscosity is affected by changes in temperature. The higher the VI, the more stable the viscosity remains over temperature fluctuations.

This hypothesis has been refuted by studies showing that air and water are not absorbed. Recent studies suggest that an effect called superlubricity can also account for graphite's lubricating properties. The use of graphite is limited by its tendency to facilitate pitting corrosion in some stainless steel,Galvanic Corrosion . keytometals.com and to promote galvanic corrosion between dissimilar metals (due to its electrical conductivity).

Micrococci, like many other representatives of the Actinobacteria, can be catabolically versatile, with the ability to utilize a wide range of unusual substrates, such as pyridine, herbicides, chlorinated biphenyls, and oil. They are likely involved in detoxification or biodegradation of many other environmental pollutants. Other Micrococcus isolates produce various useful products, such as long-chain (C21-C34) aliphatic hydrocarbons for lubricating oils.

The onset of vasocongestion results in swelling of the clitoris, labia minora, and vagina. The muscle that surrounds the vaginal opening tightens and the uterus elevates and grows in size. The vaginal walls begin to produce a lubricating liquid. The second phase, called the plateau phase, is characterized primarily by the intensification of the changes begun during the excitement phase.

Vulva with vaginal lubrication (pubic hair trimmed). Vulva with vaginal lubrication and discharge, post-coitus. The lubricating fluid can vary in consistency, texture, taste, colour, and odour, depending on sexual arousal, the phase of the menstrual cycle, the presence of an infection, certain drugs, genetic factors, and diet. Vaginal fluid is slightly acidic and can become more acidic with certain sexually transmitted diseases.

Lubricating greases are commonly formulated as mixtures of an oil and a lithium soap.Angelo Nora, Alfred Szczepanek, Gunther Koenen, "Metallic Soaps" in Ullmann’s Encyclopedia of Industrial Chemistry 2005 Wiley-VCH, Weinheim. Some formulations include PTFE or other substances, such as molybdenum disulfide. Lithium grease adheres particularly well to metal, is non- corrosive, may be used under heavy loads, and exhibits good temperature tolerance.

Born in Aurora, Indiana, Rowbottom moved with his parents to Ludlow, Kentucky, in 1885. He attended the common schools, and graduated from Ludlow High School in 1901. He then attended Kentucky State College at Lexington 1902–1904. From 1904 to 1907 Rowbottom worked selling lubricating oils and then attended the Cincinnati Business College where he graduated in accountancy in 1907.

Polytetrafluorethylene (PTFE) is widely used as an additive in lubricating oils and greases. Due to the low surface energy of PTFE, stable unflocculated dispersions of PTFE in oil or water can be produced. Contrary to the other solid lubricants discussed, PTFE does not have a layered structure. The macro molecules of PTFE slip easily along each other, similar to lamellar structures.
|
|
In view of the soft texture of the sodium salt, which is the main component of soap, other salts are also useful for their lubricating properties. Lithium stearate is an important component of grease. The stearate salts of zinc, calcium, cadmium, and lead are used to soften PVC. Stearic acid is used along with castor oil for preparing softeners in textile sizing.

The naphtha fuel was an acceptable lubricant and this avoided the problem of separating lubricating oil from condensed fuel vapour leaking past the piston ring seals. It did however require careful sealing of the crankcase. The engine valvegear was simple, compared to that of contemporary steam engines. A single rotating overhead camshaft ran above the cylinders, parallel to the crankshaft.

The CETA-cart also got a new coupler. The EVA also included lubricating the end effector capture snares on the station's robot arm - similar to what was done to the other end on an STS-126 spacewalk in late 2008. This has been proven to prevent the snare from snagging or not returning snugly into its groove inside the latching mechanism.

During this heating, the lubricating oils are burned off, leaving a dry surface. Lubricant oils may not be completely burnt off for hard temper rolls, which can make subsequent coating or printing more difficult. The rolls of aluminium foil are then slit on slitter rewinding machines into smaller rolls. Roll slitting and rewinding is an essential part of the finishing process.

The McKittrick Tar Pits have been known to the local Native American population, the Yokuts, from prehistoric times. They used the asphaltum as a sealant, for waterproofing, for decoration, for adhesive, and for trade. In the 1860s, San Joaquin Valley settlers made the first attempts to mine the asphaltum, digging pits, trenches, and tunnels. They refined the viscous substance onsite, making it into lubricating oil and kerosene.

Inside, the hull was divided into eight watertight compartments protected by a continuous double bottom. The ice belt consisted of thick shell plating and transverse frames every . The main and auxiliary engine rooms were located amidships below the main deck with the propulsion motors in their own watertight compartments. The remaining space was taken up by tanks for fuel and lubricating oil, fresh water and ballast.

Besides cooling, cutting fluids also aid the cutting process by lubricating the interface between the tool's cutting edge and the chip. By preventing friction at this interface, some of the heat generation is prevented. This lubrication also helps prevent the chips from being welded onto the tool, which would interfere with subsequent cutting. Extreme pressure additives are often added to cutting fluids to further reduce tool wear.

This alloy plays an important role in manufacturing tools for use around explosive gases, and in cryogenics. It is used as a test control metal for protective coatings research. Other items include plates, tubes, pipes, forgings, castings, bushings, washers, terminals, connectors, flexible metal hose, and conductors. In 1922, the Western Cartridge Company introduced a copper-washed bullet jacketing called Lubaloy which stands for lubricating alloy.

Chemical plants were built during the war to produce nitric acid, ammonia and ammonium nitrate fertiliser. The plant was funded by Ministry of Supply; it was operated by Trimpell Limited and later by ICI. A case of sabotage was reported in 1958 when after two compressors failed. Investigations revealed that abrasive grinding paste had been introduced into the compressors’ lubricating oil system which damaged the bearings.

The determination of trace acids in organic matrices is a common analytical task assigned to titrimetry. Examples are Total Acid Number (TAN) in mineral and lubricating oils and Free Fatty Acids (FFA) in edible fats and oils. Automated potentiometric titration procedures have been granted standard method status, for example by ASTM for TAN and AOAC for FFA. The methodology is similar in both instances.

Synthetic motor oil Given that they are non- polar, oils do not easily adhere to other substances. This makes them useful as lubricants for various engineering purposes. Mineral oils are more commonly used as machine lubricants than biological oils are. Whale oil is preferred for lubricating clocks, because it does not evaporate, leaving dust, although its use was banned in the USA in 1980.

Samples of oil were taken and after analysis, proved to be lubricating oil. Operating on the theory that the U-boat was not sunk but was proceeding submerged and bleeding oil, Chickadee conducted a box search in the vicinity of the origin of the slick. The results were again negative. It was observed that the current was flowing in the direction of the wind.
|
|
The pallets are often made of very hard materials such as polished stone (for example, artificial ruby), but even so they normally require lubrication. Since lubricating oil degrades over time due to evaporation, dust, oxidation, etc., periodic re-lubrication is needed. If this is not done, the timepiece may work unreliably or stop altogether, and the escapement components may be subjected to rapid wear.
|
|
The overhead camshaft was also driven from the crankshaft via worm gears and a vertical shaft at the rear of the engine. The camshaft operated the valves by rockers with rollers on their camshaft ends and adjusting screws at the other. Lubricating oil was mechanically pumped through cast-in channels in the crankcase to all the crankshaft bearings. The camshaft was contained in an oil tight sleeve.

If increased corneal exposure is detected, several preventive measures can be done to prevent keratitis. Aritificial eye drops and eye ointments may be used to keep the eyes moist. Since frequent use of eye drops with preservatives can promote inflammation, it is better to choose preservative free artificial tear drops and lubricating eye drops. Bandage silicone hydrogel or scleral contact lens may be used to protect cornea.

In 1861, the existing oil shale refiners switched to petroleum feedstock, and the oil shale mines shut down. In the 1800s, the principal refined product was kerosene for illuminating oil. The heaviest fraction was used as lubricating oil. A market developed for fuel oil as it was discovered that petroleum was superior to coal in powering the large engines of ships and railroad locomotives.

The fourth category, synthetic polymers, are generally stable, durable, do not leach or give off appreciable odors, and have proven to be the most environmentally friendly. Abatement oil (an organic, lubricating and penetrating oil) is most commonly used to remove debris such as dust and asbestos. Application of this product is normally done by lathering onto the surface and then removing with a clean dry cloth.

Artificial tears are the recognized treatment of choice for this problem. Artificial tears work by adding similar lubricating elements that natural tears contain. This helps thicken and stabilize the pre-corneal tear film, prolonging tear film breakup time, and allowing for tears to properly protect the surface of the eyes. Most artificial tears do not require a prescription and can be used as often as needed.

Alkanes from hexadecane upwards form the most important components of fuel oil and lubricating oil. In the latter function, they work at the same time as anti-corrosive agents, as their hydrophobic nature means that water cannot reach the metal surface. Many solid alkanes find use as paraffin wax, for example, in candles. This should not be confused however with true wax, which consists primarily of esters.

He was known to be a production genius. His motto was "get it done". After WWII, he resigned from Houdaille and formed Frontier Industries by putting together a group of four diversified manufacturing companies, Buffalo Arms, Buffalo Crushed Stone, Fairmount Tool and Forging Company of Cleveland, Ohio, and Manzel Brothers, manufactures of lubricating machines. In 1955 Frontier Industries merged with Detroit-based Houdaille-Hershey.

The refinery took heavy naphthenic crude as a feedstock and produced bitumen and other distillate products such as gas oil, marine diesel, lubricating base stocks. The throughput in the 1970s was 400,000 tonnes per year. In 1989 the unit was expanded to provide a capacity of 1.2 million tonnes per year. Eastham refinery was later operated by Briggs Oil in a joint venture with Shell.

This grease improves water resistance of the flashlights and protects threads from wearing out. Silicone grease is used with waterproof devices, as it has a very thick body and doesn't dissolve in water as most spirits and other liquids would. Various household uses include lubricating door hinges, shower heads, threads on bolts, garden-hose threads or any thread or mechanism that can be lubricated.

The rectum should be cleared of stool impaction, using anaesthetic lubricating jelly. If the noxious precipitating trigger cannot be identified, drug treatment is needed to decrease elevating intracranial pressure until further studies can identify the cause. Drug treatment includes the rapidly acting vasodilators, including sublingual or topical nitrates or oral hydralazine or clonidine. Ganglionic blockers are also used to control sympathetic nervous system outflow.

Bearings can be lubricated by a metal ring that rides loosely on the central rotating shaft of the bearing. The ring hangs down into a chamber containing lubricating oil. As the bearing rotates, viscous adhesion draws oil up the ring and onto the shaft, where the oil migrates into the bearing to lubricate it. Excess oil is flung off and collects in the pool again.
|

Composite bearings are designed with a self-lubricating polytetrafluroethylene (PTFE) liner with a laminated metal backing. The PTFE liner offers consistent, controlled friction as well as durability whilst the metal backing ensures the composite bearing is robust and capable of withstanding high loads and stresses throughout its long life. Its design also makes it lightweight-one tenth the weight of a traditional rolling element bearing.

There are no water passages in the block, which adds considerable strength and stiffness. The engine is cooled by the incoming air/fuel mixture and the lubricating oil. Like the original Hemi, the racing cylinder block has a deep skirt for strength. There are five main bearing caps, which are fastened with aircraft- standard-rated steel studs, with additional reinforcing main studs and side bolts("cross-bolting").

Fuel oil in the crankcase lube oil can cause the oil to chemically degrade. This means that the oil loses viscosity and is less effective when lubricating. The loss of viscosity of the lube oil causes the oil to not fully connect and lubricate the moving parts of the engine. This lack of lubrication can cause the engine to have an increased amount of wear over time.

To replace the cargo offloaded at Karachi, 8,700 bales of raw cotton were loaded, along with various quantities of fish manure, resin, rice, scrap iron, sulphur, and timber. Added to this were 1,000 barrels of lubricating oil. The ship's captain was concerned about having to take the flammable items but was told that they had to go. A proposal to add 750 drums of turpentine was refused.

Three-spindle screw pumps are used for transport of viscous fluids with lubricating properties. They are suited for a variety of applications such as fuel-injection, oil burners, boosting, hydraulics, fuel, lubrication, circulating, feed and so on. Compared to centrifugal pumps, positive-displacement pumps have several advantages. The pumped fluid is moving axially without turbulence which eliminates foaming that would otherwise occur in viscous fluids.

Starting fluid is not recommended for regular use with some two-stroke engines because it does not possess lubricating qualities by itself. Lubrication for two-stroke engines is achieved using oil that is either mixed into the fuel by the user or injected automatically into the fuel supply; engines requiring premixed fuel that are run solely on starting fluid do not receive an adequate supply of lubrication to their crankcase and cylinder(s). Engines that haven't been run recently are especially vulnerable to damage from oil starvation; starting fluid, a strong solvent, tends to strip residual oil off of cranks and cylinder walls, further reducing lubrication during the period of fuel starvation. WD-40 was previously recommended for use on two stroke engines because it has lubricating qualities, but the formulation with non-flammable CO2 as propellant instead of propane no longer has the same propulsive effect.

|
The main letdown was the pre-war DKW based engine that was competitive when launched, but from the late 1950s into the 1960s, small economy cars in western countries that used two-stroke engines were replaced with cleaner and more efficient four-stroke engines, as employed from the start in the Volkswagen Beetle. Two-stroke engines of this sort, with crankcase scavenging and lubricating oil provided during fuel intake, burn their lubricating oil by design and produce smoky tailpipe emissions. However, two-stroke engines were also to be found in cars like the Western German Auto Union 1000 that ended production in 1963, and the Swedish Saab 96 that changed to four-stroke in 1967. The lack of development funds in East Germany forced the continued use of a two-stroke engine in the Trabant, thus causing this vehicle to become obsolescent in the 1960s and extremely obsolete by the 1980s.

It also required less power for running in level ice than traditional designs, resulting in 40–50% reduction in ice resistance due to lubricating effect of propeller-induced water flow, more open stern design and the propellers being allowed to mill (crush) the ice. The icebreaking capability of an Azipod-equipped icebreaker operating astern in level ice was also found out to be superior to traditional icebreakers regardless of propulsion arrangement.

Retrieved 28 August 2020. According to J. F. C. Fuller, the Ricardo engine was of a "somewhat unorthodox design", but it was highly efficient and, with proper care and attention, gave very little trouble. This 'unorthodox' description related to Ricardo's use of crosshead pistons which separated the lubricating oil from the heat of combustion, with the crosshead and gudgeon pin running in its own separate guide.Fletcher (2011), pp. 5–6.

It can be used as a dry powder, in water or oil, or as colloidal graphite (a permanent suspension in a liquid). An estimate based on USGS graphite consumption statistics indicates that 2,200 tonnes was used in this fashion in 2005. Metal can also be impregnated into graphite to create a self-lubricating alloy for application in extreme conditions, such as bearings for machines exposed to high or low temperatures.

Due to the elimination of metallic contact and adhesion by the generation of oxide, friction and wear is reduced. Effectively, such a surface is self- lubricating. As the "glaze" is already an oxide, it can survive to very high temperatures in air or oxidising environments. However, it is disadvantaged by it being necessary for the base metal (or ceramic) having to undergo some wear first to generate sufficient oxide debris.

This rotary engine is most famous for its application in the Mazda RX-7 and RX-8. Splash lubrication is a rudimentary form of oil cooling. Some slow- turning early engines would have a "splashing spoon" beneath the big end of the connecting rod. This spoon would dip into sump oil and would hurl oil about, in the hope of cooling and lubricating the underside of the piston.

Neopentyl glycol (IUPAC name: 2,2-dimethylpropane-1,3-diol) is an organic chemical compound. It is used in the synthesis of polyesters, paints, lubricants, and plasticizers. When used in the manufacture of polyesters, it enhances the stability of the product towards heat, light, and water. By esterification reaction with fatty or carboxylic acids, synthetic lubricating esters with reduced potential for oxidation or hydrolysis, compared to natural esters, can be produced.

Although a highly ingenious escapement design, the Daniels coaxial nevertheless still needs lubrication to the lever pallet pivots. In addition, because of its geometry the impulse wheel can only have a limited number of teeth, thus it is necessary to have an extra wheel and pinion in the wheel train the pivots of which also need lubricating. Therefore, the advantages of this escapement over the lever are of an uncertain value.

Subpreputial wetness is a lanolin-like wetness commonly found under the prepuce in most female and male individuals who have not undergone circumcision, as well as in the female vulva area. If allowed to accumulate along with dead epithelial cells, the combination is commonly called smegma. Smegma is a whitish substance which can be removed by washing, whereas subpreputial wetness is a transparent lubricating secretion. The two substances are commonly confused.

Consumer products to control flatulence often contain silicone oil. Silicone oils have been used as a vitreous fluid substitute to treat difficult cases of retinal detachment, such as those complicated with proliferative vitreoretinopathy, large retinal tears, and penetrating ocular trauma. Additionally, silicone oil is used in general medicine and surgery. Because of silicone oil's water repellent and lubricating properties, it is considered an appropriate material to maintain surgical instruments.

People with dermatochalasis often also have blepharitis, a condition caused by the plugging of glands in the eye that produce lubricating fluid (meibomian glands). Dermatochalasis can be severe enough that it pushes the eyelashes into the eye, causing entropion. Weakness in the orbital septum may cause the herniation of the orbital fat pads. This is observed as the presence of bulges (fat pads) in the soft tissue of the baggy eyes.

He refined the light oils to a water-white burning oil. The heavy oils he refined to a quality grade of paraffine lubricating oil. From the paraffine oil he obtained a solid white paraffine, which melted at about . "Canada pitch" was of a limited supply so Atwood experimented with gas coals of the Ohio valley, the albertite of New Brunswick, the boghead mineral from Scotland, Trinidad pitch, and petroleum.

The feedstock for paraffin is slack wax, which is a mixture of oil and wax, a byproduct from the refining of lubricating oil. The first step in making paraffin wax is to remove the oil (de-oiling or de-waxing) from the slack wax. The oil is separated by crystallization. Most commonly, the slack wax is heated, mixed with one or more solvents such as a ketone and then cooled.

Ferrography is a specialized type of oil analysis used to study particle wear on machine components through analysis of contaminants in lubricating oil. It can be used to predict and diagnose errors occurring on machinery. Ferrography is related to tribology, which is the study of friction between interacting surfaces. Since the advent of ferrography in the 1970s it has been used in many industrial settings as a form of preventative maintenance.

On November 12, 1908, Feargus Squire announced that he was retiring from Standard Oil, effective January 1, 1909. He claimed exhaustion as his rationale. His son, Reginald, who was also employed by Standard Oil, resigned at the same time. (He joined the Lubric Company, manufacturer of lubricating oils and greases.) Feargus Squire and his wife, Louisa, spent 1909 and 1910 touring Europe, the Middle East, China, Japan, Micronesia, Polynesia, and Melanesia.

Synovial fluid contains lubricin (also known as PRG4) as a second lubricating component, secreted by synovial fibroblasts. Chiefly, it is responsible for so-called boundary-layer lubrication, which reduces friction between opposing surfaces of cartilage. There also is some evidence that it helps regulate synovial cell growth. It also contains phagocytic cells that remove microbes and the debris that results from normal wear and tear in the joint.

|
Oil consumption was also very high. Due to primitive carburetion and absence of a true sump, the lubricating oil was added to the fuel/air mixture. This made engine fumes heavy with smoke from partially burnt oil. Castor oil was the lubricant of choice, as its lubrication properties were unaffected by the presence of the fuel, and its gum-forming tendency was irrelevant in a total-loss lubrication system.

The second method used to advance (or retard) the ignition timing is called vacuum timing advance. This method is almost always used in addition to mechanical timing advance. It generally increases fuel economy and driveability, particularly at lean mixtures. It also increases engine life through more complete combustion, leaving less unburned fuel to wash away the cylinder wall lubrication (piston ring wear), and less lubricating oil dilution (bearings, camshaft life, etc.).

Lanes have a wood or synthetic surface onto which protective lubricating oil is applied in different specified oil patterns that vary ball path trajectories and characteristics. Common types of pin bowling include ten-pin, candlepin, duckpin, nine-pin, five-pin and kegel. The historical game skittles is the forerunner of modern pin bowling. In target bowling, the aim is usually to get the ball as close to a mark as possible.

In Siberia, temperatures down to – 60 °C may occur, and in technical process plants + 100 °C may be exceeded. Using the proper lubricant is crucial for full operation under these conditions. Greases which may be used at room temperature can become too solid at low temperatures for the actuator to overcome the resistance within the device. At high temperatures, these greases can liquify and lose their lubricating power.

|
Water-cooled models use engine coolant to keep lubricating oil cooler, avoiding possible oil coking (destructive distillation of engine oil) from the extreme heat in the turbine. The development of air-foil bearings removed this risk. Ball bearings designed to support high speeds and temperatures are sometimes used instead of fluid bearings to support the turbine shaft. This helps the turbocharger accelerate more quickly and reduces turbo lag.

In between the parietal and visceral pericardial layers there is a potential space called the pericardial cavity, which contains a supply of lubricating serous fluid known as the pericardial fluid. Pericardial recesses are small spaces in the pericardial cavity. Pericardial fluid filling these recesses may mimic mediastinal lymphadenopathy. When the visceral layer of serous pericardium comes into contact with heart (not the great vessels) it is known as the epicardium.

If necessary the linkages were present so both motors and screws could be driven by either one of the two generator sets. Only the boiler feed and main lubricating pumps, driven directly from the steam turbines, were not electrical. Those included everything from cargo winches and other ship's auxiliary machinery to 365 Westinghouse stateroom fans. The 180 ship's auxiliary motors ranged from a tenth horsepower to the 13,250 horsepower main motors.

A turbo timer is a device designed to keep an automotive engine running for a pre-specified period in order to automatically execute the cool-down period required to prevent premature turbo wear and failure. After a period of driving when a turbocharger has been working hard, it is important to let the engine run at idle speed for a period, allowing the compressor assembly to cool from the lower gas temperatures in both the exhaust and intake tracts. At the same time the lubricating oil from the engine is able to circulate properly so the turbine won't burn the lubricating oil that would otherwise be trapped within the charger with the turbine rotating at high speed. With regard to modern automotive turbochargers, the need for a turbo timer can be eliminated by simply ensuring the car does not produce any 'boost' (during driving) for several minutes prior to the ignition being shut off.

It does, however, have a pigment layer where the eyes should be, probably a vestige of the retina. Both lachrymal glands and Jacobson's organ are well developed, and it has been suggested that the former plays a role in lubricating the nasal passages and Jacobson's organ. The external ear openings are covered with fur and do not have a pinnae. The nostrils are small vertical slits right below the shield-like rostrum.

The MK5000C carried 5300 US gallons (20,100 L) of diesel, 246 US gal (931 L) of lubricating oil, and 320 gallons (1,210 L) of coolant. This coolant system was unlike that of most other North American locomotives, using a water/antifreeze mix; only with a few Caterpillar repowered switchers and the Electro Motive Division SD90MAC share this trait. The MK5000C generated of continuous tractive effort, and produced around 35% adhesion on dry rail.

He also worked with the American Field Service where he was attached to the 1st French Army from 1915 to 1916. In 1917, when the United States entered the war, he served in the United States Army with the rank of captain. He was responsible for procurement, storage, and distribution of lubricating oils for the American Expeditionary Forces. After he was discharged from the military in January 1919, he remained engaged in the oil business.

Many of the environmentally friendly alternatives have essentially the same formula as soap powders, merely lubricating and realigning the soil with no effective binding property. Many of the new approaches rely on large amounts of clay with its inherent binding properties. Bitumen, tar emulsions, asphalt, cement, lime can be used as a binding agents for producing a road base. When using such products issues such as safety, health and the environment must be considered.

Between the two plates is pumped lubricating oil. A rubber seal around the edges of the plates protected against the oil escaping under the high forces experienced during the lift. The oil in the container was connected to a hydraulic pump through a small pipe. This hydraulic system was capable of lifting loads using a pressure of 78 kgf/cm² (7.6 MPa), although the reasons for this were a mystery to Tjokorda at that time.

Frelon is a polytetrafluoroethylene (PTFE) based material with other proprietary fillers to increase bearing characteristics, such as low wear, low friction, and high strength. It is chemically inert and self lubricating. It qualifies as a class III plain bearing. The load capacity of a frelon-lined bearing is typically four to eight times that of a comparable ball bearing; for instance, a Frelon-lined bearing can support the same load as a ball bearing.

Two servicing missions to the Hubble Space Telescope have replaced a reaction wheel. In February 1997, the Second Servicing Mission (STS-82) replaced one after 'electrical anomalies', rather than any mechanical problem. Study of the returned mechanism provided a rare opportunity to study equipment that had undergone long-term service (7 years) in space, particularly for the effects of vacuum on lubricants. The lubricating compound was found to be in 'excellent condition'.

These rubber fixtures form a barrier that holds factory applied lubricating grease inside the pin and bushing wear areas. Further, the rubber o-rings prevent dirt and other contaminants from entering inside the chain linkages, where such particles would otherwise cause significant wear. There are also many chains that have to operate in dirty conditions, and for size or operational reasons cannot be sealed. Examples include chains on farm equipment, bicycles, and chain saws.

Manual disimpaction may be performed by lubricating the anus and using one gloved finger with a scoop-like motion to break up the fecal mass. Most often manual disimpaction is performed without general anaesthesia, although sedation may be used. In more involved procedures, general anaesthesia may be used, although the use of general anaesthesia increases the risk of damage to the anal sphincter. If all other treatments fail, surgery may be necessary.

Nonylphenols are a family of closely related organic compounds composed of phenol bearing a 9 carbon-tail. Nonylphenols can come in numerous structures, all of which may be considered alkylphenols. They are used in manufacturing antioxidants, lubricating oil additives, laundry and dish detergents, emulsifiers, and solubilizers. These compounds are also precursors to the commercially important non-ionic surfactants alkylphenol ethoxylates and nonylphenol ethoxylates, which are used in detergents, paints, pesticides, personal care products, and plastics.

A firm that exemplified all of the above was the Standard Oil alliance. To monopolize the market, Standard Oil integrated horizontally with other competing oil companies in addition to vertically, with tankers, lubricating oil, and acid restoration companies. Soon, the alliance dominated the oil industry through sheer economic might due to both its large economies of scale and its organizational structure. As Standard Oil continued to expand into different markets, its organizational needs changed.

The Strathcona Refinery is an oil refinery located in Strathcona County adjacent to Edmonton, Alberta, Canada, owned by Imperial Oil. The refinery provides oil products, primarily gasoline, aviation fuel, diesel, lubricating oils, petroleum waxes, heavy fuel oil and asphalts. The refinery was built in 1975 and replaced older refineries in Edmonton, Regina, Winnipeg, and Calgary. A fire occurred at the refinery in 2007 that resulted it in temporarily operating at reduced capacity.

The enclosure of the shaft and bearing also had advantages for enclosing the bearings to exclude dirt and to contain lubricating oil. Francis Webb's form of radial axle design for the LNWR used a cannon box. A radial axle is a form of single axle pony truck, where instead of a pivoted frame, the two axle bearings can slide sideways in a circular track. Webb's design placed them into a curved cannon box.

Technology was not advanced enough and the manufacturer had no way of fully loading the machine for a thorough test before shipping. One of the troubles that developed when the turbine was in operation was with lubrication. The mechanism around the turbine shaft leaked some oil and came in contact with steam which impaired its lubricating ability. Another problem that came up because there was no testing at the manufacturer's shop was concerning thrust.

Silicone grease is commonly used for lubricating and preserving many types of rubber parts, such as O-rings, without swelling or softening the rubber, but is contraindicated for silicone rubber due to these factors. It functions well as a corrosion inhibitor and lubricant on non-metal-metal contact areas. Silicone grease is soluble in organic solvents such as toluene, xylene, mineral spirits, and chlorinated hydrocarbons. It is insoluble in methanol, ethanol, and water.

The pistons are connected to a Scotch Yoke mechanism in place of the more usual crankshaft mechanism, thus the piston acceleration is perfectly sinusoidal. This causes the pistons to spend more time at top dead center than conventional engines. The incoming charge is compressed in a chamber under the pistons, as in a conventional crankcase-charged two-stroke engine. The connecting-rod seal prevents the fuel from contaminating the bottom-end lubricating oil.

The motor oil and especially the additives also undergo thermal and mechanical degradation, which reduce the viscosity and reserve alkalinity of the oil. At reduced viscosity, the oil is not as capable of lubricating the engine, thus increasing wear and the chance of overheating. Reserve alkalinity is the ability of the oil to resist the formation of acids. Should the reserve alkalinity decline to zero, those acids form and corrode the engine.

The new Powerlet gave more shots per bulb than the soda bulb, and with the addition of a simple spacer, a Powerlet gun could use the shorter 8 gram bulb. The 12 gram Powerlet, charged with CO2 and a tiny amount of lubricating oil to keep the airgun's seals conditioned, is used by nearly all manufacturers of CO2 airguns today. In 2004, Crosman introduced a new disposable CO2 power source, the 88 gram AirSource.

Class F insulation is used for main fields and Class H insulation is used both for the interpoles and the armature. The commutator uses silver-bearing copper segments with mica splitters on epoxy- glass insulated Vee rings. A bulkhead across the generator forms a separate generator compartment, which houses an auxiliary control gear cubicle next to the cab. The radiator compartment houses a single radiator panel comprising both cooling water and lubricating oil sections.

Fats, such as butter, vegetable oils, lard, or that contained in eggs, affect the development of gluten in breads by coating and lubricating the individual strands of protein. They also help to hold the structure together. If too much fat is included in a bread dough, the lubrication effect causes the protein structures to divide. A fat content of approximately 3% by weight is the concentration that produces the greatest leavening action.

The mechanism of barrier cream varies by product. Three categories of barrier creams are used: water repellent creams, water-soluble creams, and creams designed for special applications. Moisturizing barrier cream acts as a lubricating film on the skin to prevent depletion of water (transepidermal water loss) in the skin's outermost layer, the stratum corneum. This may have a protective effect against irritant contact dermatitis and allergic contact dermatitis, which often result from such depletion.

This structure is key to its lubricating ability, which is ascribed to interchain repulsion. This leads to trapping of large quantities of solvent and the stabilization of a fluid-like cushioning layer, which enables bottle brush polymers to lower the friction between joints when external pressure is applied. Furthermore, lubricin's N-terminus is thought to create disulfide bonds between two lubricin monomers. The glycoprotein thus exists as both a monomer and a dimer.

There were also designs that employed a scavenge pump or similar to remove oil from the crankcase and return it to the lubricating-oil reservoir. Lanz hot-bulb tractors and their many imitators had this feature. This reduced oil consumption considerably. In addition, if excess crankcase oil is present on start up, there is a danger of the engine starting and accelerating uncontrollably to well past the speed limits of the rotating and reciprocating components.

The second line is pressurized and the entire process is repeated lubricating the remaining lube points. Multi point direct lubricator When the controller in the pump or external controller activates the drive motor, a set of cams turns and activates individual injectors or pump elements to dispense a fixed amount of lubricant to each individual lubrication point. Systems are easy to design, direct pump to lube point without added accessories and easy to troubleshoot.

In a gasoline or diesel engine, the pistons ride up and down within the engine maintaining a tight seal via the piston rings. Over time, the constant rubbing of the rings against the cylinder wall can polish it to a very smooth finish. This creates problems in two ways. First, the lubricating oil in the engine will not adhere properly to the smooth surface, and in the absence of an oil film the resulting friction is increased.

The tradename "Cutless" is used for these rubber bearings and this name has also, along with its misspelling 'Cutlass', become a generic term for them. Vesconite Hilube is widely used for propeller shafts because the self- lubricating, homogeneous material has a low coefficient of friction (typically 0.10 to 0.12). The result is a long wear-life. Shaft vibration can be reduced with Vesconite because it can be machined to tight tolerances to achieve small running clearances.

The Vickers R.E.P. in Antarctica as an air tractor. The second monoplane was sold to the Australian explorer Douglas Mawson for the Australasian Antarctic Expedition of 1911. It was badly damaged in a crash landing at Adelaide in October 1911, however, so it was taken to Antarctica without its wings to use as a tractor for sledges. It proved unsuccessful in this role as the low temperatures caused lubricating oil to solidify and the engine to seize.

Related processes in concrete have been studied microscopically since the 19th century. Self healing materials only emerged as a widely recognized field of study in the 21st century. The first international conference on self-healing materials was held in 2007. The field of self- healing materials is related to biomimetic materials as well as to other novel materials and surfaces with the embedded capacity for self-organization, such as the self-lubricating and self-cleaning materials.

McGraw-Hill Connect. Web. p.274 They are constructed to allow for different degrees and types of movement. Some joints, such as the knee, elbow, and shoulder, are self- lubricating, almost frictionless, and are able to withstand compression and maintain heavy loads while still executing smooth and precise movements. Other joints such as sutures between the bones of the skull permit very little movement (only during birth) in order to protect the brain and the sense organs.

Since diesel engines do not need spark ignition, they can run as long as diesel fuel is supplied. Fuel is typically supplied via a fuel pump. If the pump breaks down in an open position, the supply of fuel will be unrestricted, and the engine will run away and risk terminal failure. With turbocharged engines, the oil seals on the turbocharger may fail, allowing lubricating oil into the combustion chamber, where it is burned like regular diesel fuel.

Human tears Tears are a clear liquid secreted by the lacrimal glands (tear gland) found in the eyes of all land mammals (except for goats and rabbits). Their functions include lubricating the eyes (basal tears), removing irritants (reflex tears), and aiding the immune system. Tears also occur as a part of the body's natural pain response. Humans are the only mammals known to produce tears as part of an emotional response, such as out of joy or grief.

Methane is the predominant component of natural gas. The C6 through C10 alkanes, alkenes and isomeric cycloalkanes are the top components of gasoline, naphtha, jet fuel and specialized industrial solvent mixtures. With the progressive addition of carbon units, the simple non-ring structured hydrocarbons have higher viscosities, lubricating indices, boiling points, solidification temperatures, and deeper color. At the opposite extreme from methane lie the heavy tars that remain as the lowest fraction in a crude oil refining retort.

It is used for polishing alabaster in stonework and lubricating and cleaning pocket knives or food handling tools that use an open bearing, thus needing periodic lubrication. Light mineral oil (paraffinum perliquidum) is used as a honing oil when sharpening edge tools (such as chisels) on abrasive oil stones. Mineral oil USP or light mineral oil can be used as an anti-rust agent for blades. It is an inexpensive alternative for storing reactive metals (lithium, sodium, etc.).

The 2-cylinder engine is rated at 9 HP, and is just over 2.5 liters in size. A total-loss oiling system is used on the car, lubricating 6 main oil-ways. James & Browne also launched a 4-cylinder version (16 HP), of a similar design to the horizontal 2-cylinder engine. In 1906 a vertical-engined car was introduced known as the Vertex and available as either a 20 hp four or 30/40 hp six-cylinder.

Peritoneal mesothelioma is the name given to the cancer that attacks the lining of the abdomen. This type of cancer affects the lining that protects the contents of the abdomen and which also provides a lubricating fluid to enable the organs to move and work properly. The peritoneum is made of two parts, the visceral and parietal peritoneum. The visceral peritoneum covers the internal organs and makes up most of the outer layer of the intestinal tract.

Tremor is commonly associated with the underground movement of magmatic or hydrothermal fluids. As a plate is subducted into the mantle, it loses water from its porespace and due to phase changes of hydrous minerals (such as amphibole). It has been proposed that this liberation of water generates a supercritical fluid at the plate interface, lubricating plate motion. This supercritical fluid may open fractures in the surrounding rock, and that tremor is the seismological signal of this process.

The underlying pathophysiology is incompletely understood but is generally accepted to have both inflammatory and fibrotic components. The hardening of the shoulder joint capsule is central to the disease process. This is the result of scar tissue (adhesions) around the joint capsule. There also may be reduction in synovial fluid, which normally helps the shoulder joint, a ball and socket joint, move by lubricating the gap between the humerus (upper arm bone) and the socket in the shoulder blade.

These fuels include or can be blended to give gasoline, jet fuel, diesel fuel, heating oil, and heavier fuel oils. Heavier (less volatile) fractions can also be used to produce asphalt, tar, paraffin wax, lubricating and other heavy oils. Refineries also produce other chemicals, some of which are used in chemical processes to produce plastics and other useful materials. Since petroleum often contains a few percent sulfur-containing molecules, elemental sulfur is also often produced as a petroleum product.

The patient was operated on immediately. On the same day the Egerland encountered the U-69 and it was subsequently resupplied and refuelled. By the following day, 20 May, the ship had sailed 200 miles south. On the 28 May Egerland rendezvoused with the submarine UA. From the diary of the Egerland it is known that the UA had apparently submerged while its exhaust was still open and sea water had ingressed and mixed with the lubricating oil.

Tribofilms (boundary lubricant films, boundary lubricating films, tribo- boundary films or boundary films) are films that form on tribologically stressed surfaces. Tribofilms are mostly solid surface films that result from a chemical reaction of lubricant components or tribological surfaces. Tribofilms play an important role in reducing friction and wear in lubricated systems. They form as a result of complex mechanochemical interactions between surface materials and lubricants, and the study of tribofilm formation processes is a major field of tribology.

Sperm whaling increased until the mid-19th century, as spermaceti oil was important in public lighting (for example, in lighthouses, where it was used in the United States until 1862, when it was replaced by lard oil, which was quickly replaced by petroleum) and for lubricating the machines (such as those used in cotton mills) of the Industrial Revolution. Sperm whaling declined in the second half of the 19th century, as petroleum and other products began to replace spermaceti.

The protective boom was redesigned for the weather conditions. On 7 February, Civil Protection director Franco Gabrielli told the Italian Senate that the waters were not crystal-clear but are "within the legal limits." Environment Minister Corrado Clini told the Parliament of Italy that the amount of diesel fuel and lubricating oil on board Costa Concordia was about the cargo of a small oil tanker. Clini said any oil leakage would be highly toxic for plant and animal life.

Artificial tears are lubricating eye drops used to relieve dryness and irritation of the ocular surface. Dry eye syndrome (keratoconjunctivitis sicca) is a common ocular surface disorder and is characterized by disruption of the tear film and increased inflammation. The tear film coats the surface of the eye and is composed of 3 layers: an aqueous, lipid, and mucous layer. The aqueous layer consists of a mixture of electrolytes, enzymes, antibodies, antimicrobial proteins, and other compounds.

Although Cooper never raced in the Vanderbilt Cup, he did work with the American Matheson team in 1905 and 1906, and was entered in the 1905 American Elimination Trials on September 22, 1905. In the final day of practice for the 1905 American Elimination Trial, Cooper's Matheson had a faulty lubricating system, destroying the main engine bearing. In 1906, Cooper returned with Matheson not as a driver, but as team manager. The driver was the Italian Ralph Mongini.

Molybdenite is a mineral of molybdenum disulfide, MoS2. Similar in appearance and feel to graphite, molybdenite has a lubricating effect that is a consequence of its layered structure. The atomic structure consists of a sheet of molybdenum atoms sandwiched between sheets of sulfur atoms. The Mo-S bonds are strong, but the interaction between the sulfur atoms at the top and bottom of separate sandwich-like tri-layers is weak, resulting in easy slippage as well as cleavage planes.

In molecular biology, Pulmonary surfactant protein D (SP-D) is a protein domain predominantly found in lung surfactant. This protein plays a special role; its primary task is to act as a defence protein against any pathogens that may invade the lung. It also plays a role in lubricating the lung and preventing it from collapse. It has an interesting structure as it forms a triple-helical parallel coiled coil, helps the protein to fold into a trimer.

Gas turbines are used in many small systems due to their high efficiency, small size, clean combustion, durability and low maintenance requirements. Gas turbines designed with foil bearings and air-cooling operate without lubricating oil or coolants. The waste heat of gas turbines is mostly in the exhaust, whereas the waste heat of reciprocating internal combustion engines is split between the exhaust and cooling system. External combustion engines can run on any high-temperature heat source.

The onset of the Korean War caused an expansion of the United States Navy. On 18 February 1952, Wacissa was transferred to the Military Sea Transportation Service (MSTS) and received the designation T-AOG-59. She took part in Operation Sumac, exercises conducted in the North Atlantic from May through July 1952, and subsequently carried cargoes of high test aviation gasoline and lubricating oils to Goose Bay, Labrador, and Argentia, Newfoundland. She ran aground at Polaris Reef, Baffin Bay, on 9 October.

It had a pair of crankpins set 180o apart, one for each group of ten cylinders front and back. Lubricating oil was pumped through the crankshaft and then distributed by centrifugal force; there were two oil pumps, one for each "half" of the engine. There were two crankcase mixing chambers, each fed from its own carburettor and distributed by inlet manifolds on the two outer faces of the engine. Each half also had its own magneto, running at 3,000 rpm.

There are mainly two purposes to make these forms: one is to increase the blade's capabilities of containing and discharging sawdust, and improve the cooling and lubricating conditions. The other is to reduce the friction between the segments and the material being cut as well as the sawdust, improve the blade's cutting capability, and thus save energy and improve the blade's performance. The diamond segments of diamond grinding cup wheels also have many different forms to fit different grinding applications.

The compression-ratio is controlled by an adjustable threaded T screw on the cylinder head, bearing onto a contra piston within the cylinder bore. Diesels are preferred for endurance competition, because of their fuel's higher energy content, a mixture of ether and kerosene (with lubricating oil). They have higher torque, and for a given capacity, they can usually "swing" a larger propeller than a glow engine. Home manufacture of model aircraft engines is an established hobby in its own right.

Softening infill material will under the influence of water or displacements, attain in lower shear strength and will act as a lubricating agent. This is further sub-divided in coarse, medium, and fine for the size of the grains in the infill material or the size of the grains or minerals in the discontinuity wall. The larger of the two should be used for the description. The thickness of the infill can be very thin, sometimes not more than a dust coating.

Success of such methods should be determined by sexual function, and not just by vaginal length, as has been done in the past. Ileal or cecal segments may be problematic because of a shorter mesentery, which may produce tension on the neovagina, leading to stenosis. The sigmoid neovagina is thought to be self-lubricating, without the excess mucus production associated with segments of small bowel. Vaginoplasty may create scarring at the introitus (the vaginal opening), which requires additional surgery to correct.

Oil pump from a Toyota Coaster bus (1HZ type engine) The oiling system addresses the need to properly lubricate an engine when it's running. Properly lubricating an engine not only reduces friction between moving parts but is also the main method by which heat is removed from pistons, bearings, and shafts. Failing to properly lubricate an engine will result in engine failure. The oil pump forces the motor oil through the passages in the engine to properly distribute oil to different engine components.

Auxiliary systems such as powerful water deluges and air bubbling systems are used to reduce friction by forming a lubricating layer between the hull and the ice. Pumping water between tanks on both sides of the vessel results in continuous rolling that reduces friction and makes progress through the ice easier. Experimental bow designs such as the flat Thyssen-Waas bow and a cylindrical bow have been tried over the years to further reduce the ice resistance and create an ice-free channel.

A "Sandwich" type split shaft unit is mounted between engine and transmission and used on road maintenance vehicles, fire fighting vehicles and off-road vehicles. This unit gets the drive directly from the engine shaft and can be capable of delivering up to the complete engine power to the PTO. Usually these units come with their own lubricating system. Due to the sandwich mounting style the gearbox will be moved away from the engine requiring the driveline to accommodate the installation.

In anatomy, serous membrane (or serosa) is a smooth tissue membrane consisting of two layers of mesothelium, which secrete serous fluid. The inner layer that covers organs (viscera) in body cavities is called the visceral membrane. A second layer of epithelial cells of the serous membrane, called the parietal layer, lines the body wall. Between the two layers is a potential space, mostly empty except for a few milliliters of lubricating serous fluid that is secreted by the two serous membranes.

This lever also puts a brake on the forward landing wheels, and checks the speed of the machine as it touches the ground. The right foot also controls the pump which forces the lubricating oil faster or slower to the points where it is needed. The left foot operates the lever which controls the throttle by which the aviator can regulate the flow of gas to the engine cylinders. The average speed of the 7-foot propeller is 1,100 revolutions per minute.

It also has civilian applications as a solvent dye. Dibutyl sebacate is a desensitizer in Otto Fuel II. However, its major use is as a plasticizer in production of plastics, namely cellulose acetate butyrate, cellulose acetate propionate, polyvinyl butyral, polystyrene, and many synthetic rubbers. It can be used for plastics in use in the food packaging industry. It is also used as a lubricating ingredient in shaving lotions, and a flavoring additive in non-alcoholic beverages, ice cream, ices, candy, and baked goods.

It sheared, causing the driveshaft to rip open the lubricating oil system, and the engine seized up soon afterward. Air Force mechanics had first noticed excessive wear on the driveshafts of a Corsair in November 1984, and subsequently two others. This prompted a safety directive to check driveshaft splines during compressor work on all in-service Corsairs. The charred building stood for more than two years; the hotel owners never rebuilt because they were unable to decide on an appropriate design.

Auditor-General findings and his concerns would also be investigated and attended too. On 16 January 2020, the Railway Safety Regulator made a surprise inspection of PRASA's rolling stock maintenance facility in Braamfontein, Johannesburg. The inspection established that this large repair facility had not purchased brake blocks in six months despite needing 1,500 a month with the fleet of trains having been reduced to 32 from 144 over three years. Also missing were replacement train windows, lubricating oil and wheels.

These alloys are also primary selections for fuel, lubricating oil, and hydraulic oil tanks, piping, and instrument tubing and brackets, especially where welding is required. Alloys 3003, 6061, and 6951 are utilized extensively in brazed heat exchangers and hydraulic accessories. Recently developed alloys, such as 5086, 5454, 5456, 6070, and the new weldable aluminum-magnesium-zinc alloys, offer strength advantages over those previously mentioned. Sheet assembly of light aircraft is accomplished predominantly with rivets of alloys 2017-T4, 2117-T4, or 2024-T4.

The leaves of wild mustard are edible at the juvenile stage of the plant; they are usually boiled, such as in 18th century, in Dublin, where it was sold in the streets. During the Great Famine of Ireland, wild mustard was a common famine food, even though it often caused stomach upset. Once the seeds are ground, they produce a kind of mustard. A type of oil can be extracted from the seed which has been used for lubricating machinery.

With Mackenzie back in command on the next war patrol, Tantalus attacked a convoy on 2 November. He torpedoed and sank the Japanese cargo ship Hachijin Maru, and damaged one of the escorts, the Japanese submarine chaser Ch-1. He also sank a small Japanese coaster, Pahang Maru on 7 November that was heading to Bangkok with 75 drums of oil fuel and 9 drums of lubricating oil. Tantalus plucked eleven survivors from the water: nine Malays, a Chinese and a Japanese soldier.

Croton nut oil (CNO) has been promoted for its perceived benefits in combating climate change, greenhouse gas emissions and dependence on fossil fuels. Compared to diesel, CNO is self-lubricating and has a higher flash point making it safer and causes lower exhaust emissions. There is a limited research on the production of biodiesel from CNO but as a biofuel it can be blended in any ratio with or as a replacement for diesel in stationary equipment and generator sets.

Solid film lubricants are paint-like coatings of very fine particles of lubricating pigment blended with a binder and other additives. The lubricant is applied to a substrate by spray, dip or brush methods and, once cured, creates a solid film which repels water, reduces friction and increases the wear life of the substrate to which it has been applied. Certain film lubricants also offer additional properties such as corrosion inhibition. Solid film lubricants are used in the automotive, transportation and aerospace industries.

It has been suggested that with suitable compression and expansion technology, air can be a practical (albeit not the most efficient) refrigerant, free of the possibility of environmental contamination or damage, and almost completelyCurrent air cooling methods release a trivial amount of oil or other lubricant into the atmosphere. harmless to plants and animals. However, an explosion could result from vapors or atomized refrigerant-type compressor lubricating oils being compressed together with air, in a process similar to a diesel engine.

Most motor oils are made from a heavier, thicker petroleum hydrocarbon base stock derived from crude oil, with additives to improve certain properties. The bulk of a typical motor oil consists of hydrocarbons with between 18 and 34 carbon atoms per molecule. One of the most important properties of motor oil in maintaining a lubricating film between moving parts is its viscosity. The viscosity of a liquid can be thought of as its "thickness" or a measure of its resistance to flow.

Additionally, reduced lubricin levels have also been observed in the synovial fluid of patients with ACL injuries, and decreased lubricating ability has been found in patients with traumatic synovitis. Lubricin, which is naturally present in human cornea- eyelid interface, has also been shown to play a key role in reducing friction between the cornea and conjunctiva of the eye. Clinical trials of the use of recombinant lubricin eye drops for treatment of dry eye disease have thus far been relatively successful.

A $17 million direct digital computer control system was first installed in the Isomax plant, and later expanded to include all plants. This enabled the refinery to produce higher-grade products and reduce energy consumption. In 1984, the construction of a major lubricating oil manufacturing plant increased Richmond's lube oil base-stock output from 3,800 to a day, using hydrocracking and hydrorefining processes developed by Chevron Research. Later, in 1993, a major research breakthrough occurred when Chevron introduced Isodewaxing technology.

A practically important case is the self-oscillation of the strings of bowed instruments such as the violin, cello, hurdy-gurdy, erhu, etc. A connection between dry friction and flutter instability in a simple mechanical system has been discovered, watch the movie for more details. Frictional instabilities can lead to the formation of new self-organized patterns (or "secondary structures") at the sliding interface, such as in-situ formed tribofilms which are utilized for the reduction of friction and wear in so- called self-lubricating materials.

As the image shows, the engine fitted neatly into the cycle frame. Engines with cylinders arranged radially but only in the upper half-circle were termed fan type, or semi-radials; by about 1910 other manufacturers were building e.g. five-cylinder fan engines, most notably R.E.P. Three-cylinder fans were known as W or W-3 engines. The appeal of the fan configuration was that, because all the cylinder were above the horizontal there was little danger of the plugs being fouled by the lubricating oil.

Close up of an earthworm in garden soil Earthworms travel underground by the means of waves of muscular contractions which alternately shorten and lengthen the body (peristalsis). The shortened part is anchored to the surrounding soil by tiny clawlike bristles (setae) set along its segmented length. In all the body segments except the first, last and clitellum, there is a ring of S-shaped setae embedded in the epidermal pit of each segment (perichaetine). The whole burrowing process is aided by the secretion of lubricating mucus.

When these crevasses form, the entirety of the lake's (relatively warm) contents can reach the base of the glacier in as little as 2–18 hours – lubricating the bed and causing the glacier to surge. Water that reaches the bed of a glacier may freeze there, increasing the thickness of the glacier by pushing it up from below. Finally, bed roughness can act to slow glacial motion. The roughness of the bed is a measure of how many boulders and obstacles protrude into the overlying ice.

Floyd D. Rose first started working on what became the Floyd Rose Tremolo in 1976. He was playing in a rock band at the time, inspired by Jimi Hendrix and Deep Purple. He frequently used the vibrato bar but couldn't make his guitars stay in tune using traditional approaches like lubricating the nut, or winding the strings as little as possible around the tuning pegs. At the time, Rose made and sold jewelry, and so had the skills and tools to fabricate small metal parts.

The Fiat 128's arrangement had numerous differences. As engineered by Dante Giacosa, it featured a transverse-mounted engine with unequal-length drive shafts and an innovative clutch release mechanism -- an arrangement which Fiat had strategically tested on a previous production model for a full five years, the Primula from its less market-critical subsidiary, Autobianchi.Becker, p. 79 The layout enabled the engine and gearbox to be located side by side without sharing lubricating fluid while orienting an electrically controlled cooling fan toward fresh air flow.

It carried parts for all of the makes of cars in the various city departments. Gasoline for operating the automotive vehicles was bought in the open market and stored in two underground tanks with a combined capacity of 560 gallons. Lubricating oil was stored in tanks, two in each garage. There were three hostlers at the municipal shops whose duties consist of seeing that the automobiles were properly supplied with gasoline and oil, and were washed when necessary, the intervals between washings averaging about three months.

Nomenclature of the era indicated the .45-75 cartridge contained a diameter bullet with of gunpowder. Early Winchester ammunition boxes suggested reloading empty cartridge cases with government musket powder or with American Powder Company Deadshot Fg, Hazard Powder Company Sea Shooting Fg, DuPont Rifle FFg, Oriental Powder Company Western Sporting Fg, Laflin & Rand Orange Rifle Fg, or Austin Powder Company Rifle Powder FFg. Boxes also recommended casting bullets from an alloy of one part tin and sixteen parts lead and lubricating bullets with Japan wax or tallow.

Frelon creates a self-lubricating bearing surface by transferring some of the soft PTFE to the shafting during the running in process. It is almost universally chemically inert; the only materials that attack it are molten sodium and fluorine at elevated temperatures. It has a plain bearing pressure rating (P) of ; dry velocity rating (V) of 140 surface feet per minute (sfm) (0.71 m/s); and a PV rating of 10,000 psi sfm (0.35 MPa m/s). Additional lubrication can reduce friction and wear by 50%.

On 7 December 1941, Patoka was moored at Recife, acting as tanker, cargo, store ship, and repair ship. Here she supplied the units of Task Force 3 (later 23) with fuel, diesel, lubricating oil; gasoline stores; provisions; and repairs. Shortly after the turn of the new year 1942, she got under way for Bahia, Brazil, anchoring there on 8 January. There, she received word that ships bearing rubber and other vital war goods had left French Indochina bound for the Axis controlled ports in Europe.

Asphaltum Refinery ca 1901 Asphaltum was platted by B. F. Rouse in 1901 at the peak of an oil boom in the area. An oil refinery was built by the American Lubricating and Refining Company and operated for a short time. The oil wells which led to the town's creation were fed by shallow deposits that soon failed to yield after hundreds of wells were put down in the area. The crude oil given up by these wells was sulphurous and of low quality.

Reducing friction is vital for minimizing wear on mechanical components and preventing overheating. As the relative speed of the components rises, and as the contact force between them increases, the importance of friction mitigation increases. Various types of bearing and/or lubricant may be used to reduce friction at the interface between two components. In biological joints such as the human knee, friction is reduced by means of cartilage with a very low friction coefficient, as well as lubricating synovial fluid, which has very low viscosity.

Following shakedown training Hiwassee sailed through the Panama Canal to join the giant U.S. Pacific Fleet for the final phases of its island campaign, carrying her precious aviation gasoline and lubricating oil. She arrived Ulithi 1 April 1945, the day of the landings on Okinawa, and departed 24 April for that important island. Arriving 1 May, the ship began shuttling gasoline ashore, protected from the numerous air attacks by smoke screen. She remained off Okinawa after it was secured and until decommissioning 20 February 1946.

Although anodizing only has moderate wear resistance, the deeper pores can better retain a lubricating film than a smooth surface would. Anodized coatings have a much lower thermal conductivity and coefficient of linear expansion than aluminium. As a result, the coating will crack from thermal stress if exposed to temperatures above 80 °C (353 K). The coating can crack, but it will not peel. The melting point of aluminium oxide is 2050°C (2323°K), much higher than pure aluminium's 658°C (931°K).

Although the crew flew the plane at slow cruising speeds to nurse the engines, they were eventually overstressed from extended use. The left engine began losing power as early as the third day. Hooe taped down his trouser cuffs, donned a parachute, and rigged a lifeline to service the engines from the makeshift catwalks, but the inflight lubricating systems only delayed and could not prevent engine wear. Once the cylinders began missing, the Question Mark shortened its loops to remain within gliding distance of Van Nuys.

Marvel Mystery Oil marketing literature claims benefits which include improved lubricating qualities, primarily cleaning and friction reduction capabilities. The product has previously been marketed as a fuel additive in all kinds of engines, including aircraft (although the company no longer markets it for the latter application on their website). It has also been used as an oil additive, corrosion inhibitor, penetrating oil, and in automatic transmissions as a leak stopper and seal relubricator. Supporting evidence for claimed benefits is not provided by the manufacturer.

Pigging has been used for many years to clean large diameter pipelines in the oil industry. Today, however, the use of smaller diameter pigging systems is now increasing in many continuous and batch process plants as plant operators search for increased efficiencies and reduced costs. Pigging can be used for almost any section of the transfer process between, for example, blending, storage or filling systems. Pigging systems are already installed in industries handling products as diverse as lubricating oils, paints, chemicals, toiletries, cosmetics and foodstuffs.

Mixtures of the normal alkanes are used as boiling point standards for simulated distillation by gas chromatography.ASTM D5399-09, Standard Test Method for Boiling Point Distribution of Hydrocarbon Solvents by Gas Chromatography Alkanes from hexadecane upwards form the most important components of fuel oil and lubricating oil. In latter function they work at the same time as anti- corrosive agents, as their hydrophobic nature means that water cannot reach the metal surface. Many solid alkanes find use as paraffin wax, used for lubrication, electrical insulation, and candles.

There are a variety of chemicals, both metal and non-metal, that can be added to steel to make it easier to cut. These additives may work by lubricating the tool-chip interface, decreasing the shear strength of the material, or increasing the brittleness of the chip. Historically, sulphur and lead have been the most common additives, but bismuth and tin are increasingly popular for environmental reasons. Lead can improve the machinability of steel because it acts as an internal lubricant in the cutting zone.

It was the roller bearing designed by Hyatt coupled with Lincoln's design for the car itself that made the product successful. Continued emphasis on improving productivity in the mines led to the development of the first automatic, power-driven grease gun to be marketed commercially. Used for lubricating the mine cars, the unit included a 400 Lb pressurized tank, one or more hoses and valves that automatically dispensed a predetermined amount of grease. The first Lincoln Lubrigun, introduced in 1923, was mounted on a mine car truck.

The NLGI was incorporated by a small number of U.S. companies in 1933 to create a code for the National Recovery Act. The original name of the organization was the National Association of Lubricating Grease Manufacturers, Inc. The name was changed in 1937 as the industry recognized the need for a joint development and standards association and membership grew. The NLGI is a not-for-profit corporation whose membership includes grease manufacturers and sales organizations, associated equipment manufacturers, industry suppliers, service organizations, research and educational groups.

By 1955 OA had matured to the point that the United States Bureau of Naval Weapons began a major research program to adopt wear metal analysis for use in aircraft component failure prediction. These studies formed the basis for a Joint Oil Analysis Program (JOAP) involving all branches of the U.S. Armed Forces. The JOAP results proved conclusively that increases in component wear could be confirmed by detecting corresponding increases in the wear metal content of the lubricating oil. In 1958 Pacific Intermountain Express (P.

BMW's Telelever front suspension on a R1150R Developed by Saxon-Motodd in Britain in the early 1980s, the Telelever fork aims to improve handling stability during cornering and braking. The Telelever uses conventional telescopic forks, but the stanchions contain only lubricating oil. Springing and damping functions are dealt with by a monoshock attached to a "Telelever" wishbone. The wishbone pivots on the front of the engine block, and the wishbone's forward end is attached via a rose-joint to a brace connecting the fork sliders.

At the time, explosives were graded as Category A, B, or C. Category A explosives, such as those carried on board Fort Stikine, were the most dangerous. These were only allowed to be offloaded onto lighters, and not directly to the quayside. Unloading of Fort Stikine began with the lubricating oil, followed by the fish manure. An extra gang of stevedores were employed on this task, which continued through the night of 13–14 April. At midday on 13 April, lighters arrived for the explosives.

Oil mist may form when high pressure fuel oil, lubricating oil, hydraulic oil, or other oil is sprayed through a narrow crack, or when leaked oil connects with a high temperature surface, vaporizes, and comes in contact with low air temperature. This happens while the fluids interact with the moving parts during machining. Smaller oil droplets than oil mist are difficult to generate under normal circumstances. Bigger oil droplets than oil mist remain in spray form; this has the advantage of a higher ignition temperature.

PPEs, being of excellent thermo-oxidative stability and radiation resistance, have found extensive use in high temperature applications that also require radiation resistance. In addition, PPEs demonstrate better wear control and load-carrying ability than mineral oils, especially when used in bearings. PPEs were developed for use in jet engines that involved high speed-related frictional temperatures of as high as . While the use of PPEs in lubricating jet engines has somewhat subsided due to their higher cost, they are still used in some aerospace applications.

In 1882, the Geiger brothers, who were mechanics, built the Gebrüder Geiger, Fabrik für landwirtschaftliche Maschinen farm machinery factory. In 1900, the Zeller und Gmelin company acquired a site at the station, on which it built a refinery for plant oil and lubricating oil. In 1898, the station building received a two-storey extension to accommodate a waiting room (eastern extension), and rooms for the train dispatcher, the administration, record storage and the cashier (western extension). Also the goods shed underwent remodeling, including enlargement, in 1904.

However, jet fuel tends to have poor lubricating ability in comparison to diesel, which increases wear in fuel injection equipment. An additive may be required to restore its lubricity. Jet fuel is more expensive than diesel fuel but the logistical advantages of using one fuel can offset the extra expense of its use in certain circumstances. Jet fuel contains more sulfur, up to 1,000 ppm, which therefore means it has better lubricity and does not currently require a lubricity additive as all pipeline diesel fuels require.

The introduction of Ultra Low Sulfur Diesel or ULSD brought with it the need for lubricity modifiers. Pipeline diesels before ULSD were able to contain up to 500 ppm of sulfur and were called Low Sulfur Diesel or LSD. In the United States LSD is now only available to the off-road construction, locomotive and marine markets. As more EPA regulations are introduced, more refineries are hydrotreating their jet fuel production, thus limiting the lubricating abilities of jet fuel, as determined by ASTM Standard D445.

The types and quantities of nanoparticles can vary according to operating temperatures and pressures, presence of an open flame, fundamental fuel type and fuel mixture, and even atmospheric mixtures. As such, the resulting types of nanoparticles from different engine technologies and even different fuels are not necessarily comparable. One study has shown that 95% of the volatile component of diesel nanoparticles is unburned lubricating oil. Long-term effects still need to be further clarified, as well as the effects on susceptible groups of people with cardiopulmonary diseases.

The maximum RPM of an engine is limited to the airflow through the engine, the displacement of the engine, the mass and balance of the rotating parts, along with the bore and stroke of the pistons. Formula One engines can rev up to 15,000 rpm as per Formula One rules because of their smaller displacement, low mass, and short stroke. Engines with hydraulic tappets (such as the Buick/Rover V8) often have in effect a rev limiter by virtue of their design. The tappet clearances are maintained by the flow of the engine's lubricating oil.

The firm manufactured lubricating oil from coal, but the oil sold poorly because of its strong odor. With Downer's financial backing, the firm perfected its lubricant. After a company chemist returned from a visit to the Scottish oil shale region, the firm switched emphasis to lamp oil, which it manufactured at Waltham, as well as at another factory it built at Portland, Maine. Both works used albertite imported from New Brunswick. By the end of 1858, the Downer Company had 50 retorts, and dominated the coal oil business in the northeast.

At least 25 shale oil manufacturers set up retorts along the Ohio River and its navigable tributaries from Pittsburg on the east to St. Louis (on the Mississippi River) on the west. Major coal-oil centers were Pittsburg, with four coal-oil companies; Cincinnati, with three; and Kanawha, Virginia (now West Virginia), with six companies. Kentucky had six coal-oil manufacturers. By early 1860, there were between 60 and 75 shale oil companies in the United States, producing from seven to nine million gallons annually of lamp and lubricating oil.

As a result, the total efficiency of icebreaking ships is 20–40% less than that of good open water vessels of similar size mainly due to the bow form. In the late 1800s, captains operating ships in icebound waters discovered that sometimes it was easier to break through ice by running their vessels astern. Although not known at the time, this was because the forward-facing propellers generated a lubricating water flow that lowered the ice resistance by reducing friction between the ship's hull and ice.Aker Arctic Technology Inc.

Lubricated friction is a case of fluid friction where a fluid separates two solid surfaces. Lubrication is a technique employed to reduce wear of one or both surfaces in close proximity moving relative to each another by interposing a substance called a lubricant between the surfaces. In most cases the applied load is carried by pressure generated within the fluid due to the frictional viscous resistance to motion of the lubricating fluid between the surfaces. Adequate lubrication allows smooth continuous operation of equipment, with only mild wear, and without excessive stresses or seizures at bearings.

Barium acetate is used as a mordant for printing textile fabrics, for drying paints and varnishes and in lubricating oil. In chemistry, it is used in the preparation of other acetates; and as a catalyst in organic synthesis. Barium acetate is toxic. It was featured in a 2001 episode of the television series Forensic Files, recounting the 1993 murder of a man by his teenaged daughter (Marie Robards), though the episode and other crime documentary shows examining the Robards case willfully excluded the words "barium acetate" in hopes of preventing future "copycat" crimes.

Lacking the technical know-how to hunt them, they sought help abroad. In 1602, two Basque whalers accompanied Diogo Botelho, the newly appointed governor general of Brazil, to the colonial capital of Bahia de Todos os Santos. It was their crews that introduced commercial whaling to colonial Brazil. Each year for nearly a decade Basque ships made runs from Biscay to Brazil, where the oil they produced supplied sugar mills (engenhos) with a dependable source of fuel for nocturnal grinding, as well as oil for lubricating machinery and caulking boats and ships.

A wet clutch is immersed in a cooling lubricating fluid that also keeps surfaces clean and provides smoother performance and longer life. Wet clutches, however, tend to lose some energy to the liquid. Since the surfaces of a wet clutch can be slippery (as with a motorcycle clutch bathed in engine oil), stacking multiple clutch discs can compensate for the lower coefficient of friction and so eliminate slippage under power when fully engaged. The Hele-Shaw clutch was a wet clutch that relied entirely on viscous effects, rather than on friction.

A 17th-century gold-coated lead sculpture Lead has many uses in the construction industry; lead sheets are used as architectural metals in roofing material, cladding, flashing, gutters and gutter joints, and on roof parapets. Lead is still used in statues and sculptures, including for armatures. In the past it was often used to balance the wheels of cars; for environmental reasons this use is being phased out in favor of other materials. Lead is added to copper alloys, such as brass and bronze, to improve machinability and for its lubricating qualities.

Colloidal suspensions of nanoparticles of boric acid dissolved in petroleum or vegetable oil can form a remarkable lubricant on ceramic or metal surfaces with a coefficient of sliding friction that decreases with increasing pressure to a value ranging from 0.10 to 0.02. Self-lubricating H3BO3 films result from a spontaneous chemical reaction between water molecules and B2O3 coatings in a humid environment. In bulk-scale, an inverse relationship exists between friction coefficient and Hertzian contact pressure induced by applied load. Boric acid is used to lubricate carrom and novuss boards, allowing for faster play.

A simple labyrinth seal A labyrinth seal is a type of mechanical seal that provides a tortuous path to help prevent leakage. An example of such a seal is sometimes found within an axle's bearing to help prevent the leakage of the oil lubricating the bearing. A labyrinth seal may be composed of many grooves that press tightly inside another axle, or inside a hole, so that the fluid has to pass through a long and difficult path to escape. Sometimes screw threads exist on the outer and inner portion.

The German advance was held in front of Bucquoy, despite heavy shellfire, and on the night of 27/28 March 1/6th Manchesters sent an aggressive patrol back into Ablainzevelle, which caused casualties and disruption. The following day the battalion counter-attacked again, breaking up another German attack, and held the line all day. During one of the hottest attacks Corporal A. Brooks noticed that his men were running short of rifle oil and suffering jams, so he calmly went up and down the line with an oil can, lubricating rifle bolts while under fire.

These factors include hyaluronic acid being severely limited, strong competition between hyaluronic synthesis and cell growth, and lactic acid being the main by-product of fermentation; which also will inhibit the overall fermentation process. Since hyaluronic acid is important for the virulence of S. zooepidemicus, as well as a valuable commercial production, hyaluronic acid production is constantly trying to be increased in industry and within the organism. Commercial uses for hyaluronic acid include an ingredient in cosmetics, skin filler for anti-aging and lip injections, in viscosurgery, and a lubricating substance in arthritic joints.

In January 1943 Dover Hill loaded a cargo of fighter aircraft, guns and munitions, plus a deck cargo of Matilda II tanks, lorries in cases and drums of lubricating oil protected by sandbags. On 23 January she sailed from her anchorage off Gourock in the Firth of Clyde and on 25 January she anchored in Loch Ewe. On 15 February she sailed for the USSR as one of 28 merchant ships in Arctic convoy JW 53. The flagship was the cruiser and the convoy's other escorts included the cruisers and , escort carrier and 15 destroyers.

Topical antibiotics are used to prevent concomitant infections, which result in slower healing of corneal abrasions. Ointments are considered the first-line treatment, as they are more lubricating than drops. If the person uses contact lenses, an antibiotic with anti-pseudomonal activity is preferred (ciprofloxacin, gentamycin or ofloxacin), and the use of contact lenses should be discontinued until the abrasion has healed and the antibiotic treatment has ended. This is because contact lens wearers are often colonized with Pseudomonas aeruginosa, which may cause corneal perforations and subsequent permanent vision loss.

They do not have the lubricating qualities necessary to prevent dry eye. Because blinking coats the eye with tears, symptoms are worsened by activities in which the rate of blinking is reduced due to prolonged use of the eyes. These activities include prolonged reading, computer usage, driving, or watching television. Symptoms increase in windy, dusty or smoky (including cigarette smoke) areas, in dry environments high altitudes including airplanes, on days with low humidity, and in areas where an air conditioner (especially in a car), fan, heater, or even a hair dryer is being used.

Patients with Meesman corneal dystrophy will suffer from chronic eye dryness that can be treated with lubricating eye drops but most cases do not require further treatment. In severe cases, surgery may be required due to excessive corneal scarring such as superficial keratectomy (SK), phototherapeutic keratectomy (PTK), lamellar keratoplasty, or penetrating keratoplasty. Patients may relapse in symptoms but surgery prolongs the reoccurrence and may also lessen severity. Currently there are researchers studying the use of allele-specific siRNA against mutants with single-nucleotide specificity as a potential method of treatment for MECD.

Lakes of a diameter greater than ~300 m are capable of driving a fluid-filled crevasse to the glacier/bed interface, through the process of hydrofracture. A surface-to-bed connection made in this way is referred to as a moulin. When these crevasses form, it can take a mere 2–18 hours to empty a lake, supplying warm water to the base of the glacier - lubricating the bed and causing the glacier to surge. The rate of emptying such a lake is equivalent to the rate of flow of the Niagara Falls.

Friction welding may unintentionally occur at sliding surfaces like bearings. This happens in particular if the lubricating oil film between sliding surfaces becomes thinner than the surface roughness, which may be due to low speed, low temperature, oil starvation, excessive clearance, low viscosity of the oil, high roughness of the surfaces, or a combination thereof.Requirements to engine bearing materials, SubsTech The seizure resistance is the ability of a material to resist friction welding. It is a fundamental property of bearing surfaces and in general of sliding surfaces under load.

Comparing regular lubricating oil with two-stroke oil, the relevant difference is that two-stroke oil must have a much lower ash content. This is required to minimize deposits that tend to form if ash is present in the oil which is burned in the engine's combustion chamber. Additionally a non-2T-specific oil can turn to gum in a matter of days if mixed with gasoline and not immediately consumed. Another important factor is that 4-stroke engines have a different requirement for 'stickiness' than 2-strokes do.

In the modern English-speaking world, the term crayon is commonly associated with the standard wax crayon, such as those widely available for use by children. Such crayons are usually approximately in length and made mostly of paraffin wax. Paraffin wax is heated and cooled to achieve the correct temperature at which a usable wax substance can be dyed and then manufactured and shipped for use around the world. Paraffin waxes are used for cosmetics, candles, for the preparation of printing ink, fruit preserving, in the pharmaceutical industry, for lubricating purposes, and crayons.

A schematic of the equipment Laser cladding is a method of depositing material by which a powdered or wire feedstock material is melted and consolidated by use of a laser in order to coat part of a substrate or fabricate a near-net shape part (additive manufacturing technology) . It is often used to improve mechanical properties or increase corrosion resistance, repair worn out parts, and fabricate metal matrix composites. Surface material may be laser cladded directly onto a highly stressed component, i.e. to make a self-lubricating surface.

This pump pressurizes Normal ATF (0-288 psi) into the transfer case to engage the clutch pack. This fluid only engages the clutch pack and does not mix with the NS-ATF lubricating the transfer case. The higher the fluid pressure the transfer case is supplied with from the pump, the more the clutch pack engages, enabling the torque to the front wheels to be varied. Exiting the transfer case, the front drive shaft runs along the right side of the transmission, into a differential located on the right of the engines sump.

The alkalinity of the prostatic fluid serves to neutralize the acidity of the female vaginal tract in order to prolong the survival of sperm in this harsh environment. Semen is now a fructose-rich, alkaline fluid containing sperm as it enters the bulbourethral glands below the prostate. The bulbourethral glands secrete a small amount of clear fluid into the urethra before the ejaculate is expelled. The functions of this fluid are not entirely known but are suggested to aid in lubricating the male urethra in preparation for the semen during ejaculation.

Because enemas work in 2–15 minutes, they do not allow sufficient time for a large fecal mass to soften. Even if the enema is successful at dislodging the impacted stool, the impacted stool may remain too large to be expelled through the anal canal. Mineral oil enemas can assist by lubricating the stool for easier passage. In cases where enemas fail to remove the impaction, polyethylene glycol can be used to attempt to soften the mass over 24–48 hours, or if immediate removal of the mass is needed, manual disimpaction may be used.

The alkanes, also known as paraffins, are saturated hydrocarbons with straight or branched chains which contain only carbon and hydrogen and have the general formula CnH2n+2. They generally have from 5 to 40 carbon atoms per molecule, although trace amounts of shorter or longer molecules may be present in the mixture. The alkanes from pentane (C5H12) to octane (C8H18) are refined into gasoline, the ones from nonane (C9H20) to hexadecane (C16H34) into diesel fuel, kerosene and jet fuel. Alkanes with more than 16 carbon atoms can be refined into fuel oil and lubricating oil.

A vacuum ceramic filter is designed to separate liquids from solids for dewatering purposes. The device consists of a rotator, slurry tank, ceramic filter plate, distributor, discharge scraper, cleaning device, frame, agitating device, pipe system, vacuum system, automatic acid dosing system, automatic lubricating system, valve and discharge chute. The operation and construction principle of vacuum ceramic filter resemble those of a conventional disc filter, but the filter medium is replaced by a finely porous ceramic disc. The disc material is inert, has a long operational life and is resistant to almost all chemicals.

FOCS 1, a caesium atomic clock in Switzerland Lithium, sodium, and potassium have many applications, while rubidium and caesium are very useful in academic contexts but do not have many applications yet. Lithium is often used in lithium-ion batteries, and lithium oxide can help process silica. Lithium stearate is a thickener and can be used to make lubricating greases; it is produced from lithium hydroxide, which is also used to absorb carbon dioxide in space capsules and submarines. Lithium chloride is used as a brazing alloy for aluminium parts.

Lanolin is a popular additive to moustache wax, particularly 'extra-firm' varieties. Lanolin is used as a primary lubricating component in aerosol-based brass lubricants in the ammunition reloading process. Mixed warm 1:12 with highly concentrated ethanol (usually 99%), the ethanol acts as a carrier which evaporates quickly after application, leaving a fine film of lanolin behind to prevent brass seizing in resizing dies. Lanolin, when mixed with ingredients such as neatsfoot oil, beeswax and glycerol, is used in various leather treatments, for example in some saddle soaps and in leather care products.

Mild conjunctivochalasis can be asymptomatic and in such cases does not require treatment. Lubricating eye drops may be tried but are often ineffective. If discomfort persists after standard dry eye treatment and anti- inflammatory therapy, surgery may be undertaken to remove the conjunctival folds and restore a smooth tear film. This conjunctivoplasty surgery to correct conjunctivochalasis typically involves resection of an ellipse-shaped segment of conjunctiva just inferior to the lower lid margin, and is usually followed either by suturing or amniotic membrane graft transplantation to close the wound.

The smaller piston is purely a mechanical guide. It runs within a small cylinder as a trunk guide and also carries the gudgeon pin. Lubrication of the crosshead has advantages over the trunk piston as its lubricating oil is not subject to the heat of combustion: the oil is not contaminated by combustion soot particles, it does not break down owing to the heat and a thinner, less viscous oil may be used. The friction of both piston and crosshead may be only half of that for a trunk piston.

The 2009 to 2010 model year Toyota Matrix (and its Pontiac Vibe relative) are subject to the 2009–2011 Toyota vehicle recalls regarding floor mat and accelerator pedal replacement. On October 10, 2012, Toyota issued a recall for 2009 model year Corolla and Matrix, along with 10 other models. The recall notices states that improperly lubricated driver's side power window master switch may develop a “notchy” or sticky feel, and that improper aftermarket lubrication may present a fire hazard. The repair involves lubricating the switch assembly with a special fluorine grease.

The station had sufficient operating power to carry out its near-term programme with only modest impacts on operations, so to prevent further damage, the joint was locked in place. On 25 September 2008, NASA announced significant progress in diagnosing the source of the starboard SARJ problem and a programme to repair it on orbit. The repair programme began with the flight of the on STS-126. The crew carried out servicing of both the starboard and port SARJs, lubricating both joints and replacing 11 of 12 trundle bearings on the starboard SARJ.

Vacuum Oil Company started selling lubricating oils in Europe in the late 19th century. By the 1930s its Mobiloil had become one of the main brands. Mobil gradually expanded its operation into fuels retailing as well, and opened its first UK service stations in the early 1950s, after the wartime POOL monopoly was disbanded. Mobil grew to become the seventh largest brand of petrol in Britain, supplying 1,990 outlets in 1965, and claimed in the mid-1960s to be the first company to operate 100 self-service stations.

Applying the idea of ferrography in other fields, techniques have been found to analyze wear outside of lubricating oil and of particles that do not carry magnetic properties. These uses have been found in processing grease samples, gas emissions; and in examining wear on arthritic joints. In arthritic joints, residue from bone-on-bone contact can be found in fluid near the joint and analyzed using direct-reading ferrography which can give information regarding rate of decline in the joint. As of November 2016, minimal information is available regarding further uses of ferrography.

The cup- shaped depression in the top of the jewel is the oil cup; its purpose is to hold the lubricating oil (yellow) in contact with the bearing shaft by capillary action. In wheels where friction is critical, a capstone is added on the end to prevent the shoulder of the shaft from bearing against the face of the jewel. A jewel bearing is a plain bearing in which a metal spindle turns in a jewel-lined pivot hole. The hole is typically shaped like a torus and is slightly larger than the shaft diameter.

The instrument needs to be disinfected or sterilized after every usage to prevent infection during succeeding incisions. Due to the mechanical structure of the device, this must not be done with alcoholic disinfectant, as that would destroy the lubricants. Instead it has to be done in an autoclave after removing the drill, washing the instrument with hydrogen hydroxide and lubricating it."Maintenance Instruction for Dental Drills (Italian)""Hygiene Instructions for Dentists (German)" The United States Food and Drug Administration classes burrs as "single-use devices", although they can be sterilised with proper procedures.

In addition to the use of lubricating secretions and downward-pointing hairs common to all North American pitcher plants to force their prey into the trap, this species carefully hides the tiny exit hole from trapped insects by curling it underneath and offering multiple translucent false exits. Upon trying many times to leave via the false exits, the insect will tire and fall down into the trap. The slippery walls and hairs prevent the trapped prey from escaping. The only other species that utilizes this technique is the parrot pitcher plant, Sarracenia psittacina.

JASDF soldiers conduct operational maintenance on a Type 91 MANPAD by making a change to its battery pack during Red Flag - Alaska. Operational maintenance is the care and minor maintenance of equipment using procedures that do not require detailed technical knowledge of the equipment’s or system’s function and design. This category of operational maintenance normally consists of inspecting, cleaning, servicing, preserving, lubricating, and adjusting, as required. Such maintenance may also include minor parts replacement that does not require the person performing the work to have highly technical skills or to perform internal alignment.

With felled timber, bark should be removed in the spring with a shovel, chisel, or bark spud. The sap is still running in spring time and provides a lubricating layer of cambium between the bark and wood, making separation an easier task than if left until the fall when the two layers are well-bonded together. Once debarked, the logs should sit to dry for at least three summers to limit splitting and checking. It is important to cut the logs, once debarked to the chosen building length.

Single-acting pistons of a typical modern diesel car engine In contrast to steam engines, nearly all internal combustion engines have used single-acting cylinders. Their pistons are usually trunk pistons, where the gudgeon pin joint of the connecting rod is within the piston itself. This avoids the crosshead, piston rod and its sealing gland, but it also makes a single-acting piston almost essential. This, in turn, has the advantage of allowing easy access to the bottom of the piston for lubricating oil, which also has an important cooling function.

In normal functioning, MUC-4 is known to play anti- adhesive roles in the body, such as in lubricating the reproductive lining. It is also found in the respiratory tract - particularly in the trachea and lung - and the digestive tract - in the esophagus and colon - as well as in the visual and auditory systems. In these roles, MUC-4 serves to protect and lubricate the epithelium, which facilitates transport and traps foreign particles. One example of its function in the reproductive lining relates to blastocyst implantation resulting from MUC4 downregulation.

Behind Castrol, by 1967, it was regarded as the largest independent lubricating oil company in the UK and the third largest supplier of engine oil to motorists, producing the first multigrade oil for motorists. To cope with demand, a new manufacturing plant was opened in Aldridge, Staffordshire in 1968, shortly before the company was acquired by BP in 1969. Duckhams' Hammersmith site closed in 1979, was acquired by Richard Rogers' architects practice (today Rogers Stirk Harbour + Partners) in 1983, and was redeveloped to become the Thames Wharf Studios and the River Café.

Naphthenates are the salts of naphthenic acids, analogous to the corresponding acetates, which are better defined structurally (because they crystallize readily). Such well-defined species however exhibit low solubility in hydrophobic medias such as paints. They are generally assumed have the formula M(naphthenate)2 or are basic oxides with the formula M3O(naphthenate)6. The naphthenates have industrial applications including synthetic detergents, lubricants, corrosion inhibitors, fuel and lubricating oil additives, wood preservatives, insecticides, fungicides, acaricides, wetting agents, thickening agent of napalm and oil drying agents used in painting and wood surface treatment.

The Shell corporation uses a proprietary process for the synthesis of 1-pentadecanol (referring to it by the trade name Neodol 5) via hydroformylation of olefins produced from ethylene. Like other long-chain primary alcohols, it is used as an ingredient in industrial chemicals, lubricating oils, and consumer products such as lotions and creams. Additionally, it can be used as a feedstock for processes that use ethoxylation and sulfation reactions to produce surfactants. In 2008, a synthesis of pachastrissamine (a cytotoxic lipid compound found in sea sponges) was described starting from 1-pentadecanol.

Thread seal tape is wrapped around the threads, lubricating the connection and allowing the two pieces to be screwed deeper together. Thread seal tape (also known as PTFE tape, Teflon tape, or plumber's tape) is a polytetrafluoroethylene (PTFE) film tape commonly used in plumbing for sealing pipe threads. The tape is sold cut to specific widths and wound on a spool, making it easy to wind around pipe threads. Thread seal tape lubricates allowing for a deeper seating of the threads, and it helps prevent the threads from seizing when being unscrewed.

The engine, which was positioned flat in the frame, used hot tube ignition with the tube heater in front of the cylinder heads. The tube heater was ventilated by the lower downtubes while the upper downtubes held lubricating oil. Some design details were carried over from a steam-powered prototype made by the Hildebrand brothers in 1889, including the water tank shaped to form the rear mudguard and the connecting rods of the engine driving the rear wheel directly. The water tank was repurposed to supply water to the cooling jackets surrounding the cylinders.

On September 6, 1866, American John Ellis founded the Continuous Oil Refining Company. While studying the possible healing powers of crude oil, Dr. Ellis was disappointed to find no real medicinal value, but was intrigued by its potential lubricating properties. He eventually abandoned the medical practice to devote his time to the development of an all-petroleum, high-viscosity lubricant for steam engines – which at the time were using inefficient combinations of petroleum and animal and vegetable fats. He made his breakthrough when he developed an oil that worked effectively at high temperatures.

The viscosity must be high enough to maintain a lubricating film, but low enough that the oil can flow around the engine parts under all conditions. The viscosity index is a measure of how much the oil's viscosity changes as temperature changes. A higher viscosity index indicates the viscosity changes less with temperature than a lower viscosity index. Motor oil must be able to flow adequately at the lowest temperature it is expected to experience in order to minimize metal to metal contact between moving parts upon starting up the engine.

Millard F. Harmon, whose plane had been lost at sea. The ship arrived at Eniwetok on 13 March and, after waiting four days for a convoy bound for the Western Carolines, got underway on St. Patrick's Day and proceeded independently to Ulithi. Joining ServRon 10 a week later, she took on a cargo of gasoline, diesel oil, and lubricating oil. However, she stood by at Ulithi, awaiting instructions through all of April and the first half of May before the long-awaited orders arrived and directed her to join Task Force 51.

A typical application is monitoring of ultrapure water in semiconductor fabrication facilities. The light blocking method is specified for particle counters that are used for counting in hydraulic and lubricating fluids. Particle counters are used here to measure contamination of hydraulic oil, and therefore allow the user to maintain their hydraulic system, reduce breakdowns, schedule maintenance during no or slow work periods, monitor filter performance, etc. Particle counters used for this purpose typically use ISO Standard 4406:1999 as their reporting standard, and ISO 11171 as the calibration standard.

The first engines had the oil supply calculated with consideration of gasoline's lubricating qualities. As leaded gasoline was being phased out, Wankel engines needed an increased mix of oil in the gasoline to provide lubrication to critical engine parts. Experienced users advise, even in engines with electronic fuel injection, adding at least 1% of oil directly to gasoline as a safety measure in case the pump supplying oil to combustion chamber related parts failed or sucked in air. A SAE paper by David Garside extensively described Norton's choices of materials and cooling fins.

Often a vane pump is located on the same drive shaft to provide this pressure and it also allows the pump assembly to draw fluid against some suction head from the reservoir, which is not an attribute of the unaided axial piston pump. Another method of drawing pistons up the cylinder is to attach the cylinder heads to the surface of the swash plate. In that way the piston stroke is totally mechanical. However, the designer's problem of lubricating the swash plate face (a sliding contact) is made even more difficult.

A recent application of C14 is as on-land drilling fluid basestock, replacing diesel or kerosene in that application. Although C14 is more expensive than middle distillates, it has a significant advantage environmentally, being much more biodegradable and in handling the material, being much less irritating to skin and less toxic. C16 \- C18 linear olefins find their primary application as the hydrophobes in oil-soluble surfactants and as lubricating fluids themselves. C16 \- C18 alpha or internal olefins are used as synthetic drilling fluid base for high value, primarily off-shore synthetic drilling fluids.

Grooves or machined ramps on the seal direct gas inward toward the non-grooved portion. The action of the gas flowing across the seal generates pressure that keeps a minute gap, therefore optimizing fluid film stiffness and providing protection against face contact. The use of these seals in centrifugal compressors has increased significantly in the last two decades because they eliminate contamination and do not use lubricating oil. Non-contacting dry gas seals are often used on compressors for pipelines, off- shore applications, oil refineries, petrochemical and gas processing plants.

The synovial sac is one of the seven parts of a joint located in the body, along with muscle, tendon, ligament, bone, articular cartilage and bursa. The synovial sac is a thin tissue that lines the joint. It is filled with a fluid that works like oil in a car, lubricating the joint and making it move easily. If this sac is ruptured or destroyed from continuous use or being overweight over a long period of time, it may cause the bones to become stiff and can cause arthritis.

This PPE property tends to keep the film stationary, or at least to cause it to remain in the area where the lubrication is needed, rather than migrating away by spreading and forming a new surface. As a result, contamination of other components and equipment, which do not require a lubricant, is avoided. The high surface tension of PPEs, therefore, makes them useful in lubricating electronic contacts. Polyphenyl ether lubricants have a 30-year history of commercial service for connectors with precious and base metal contacts in telecom, automotive, aerospace, instrumentation and general-purpose applications.

Oil-in-frame (Oif) chassis, where the lubricating oil is stored in the frame of the motorcycle, was used for Vincent Motorcycles of the 1950s, and for a while during the 1970s on some NVT British motorcycles. It was widely unpopular and generally regarded as a bad idea at the time. Today it is a used on some "thumpers" (single-cylinder four-strokes) that usually have dry-sump lubrication requiring an external oil tank. It has since gained some cachet in the modern custom bike world too because of the space savings it can afford and the reference to an earlier era.

212x212px Rotary-screw compressors use two very closely meshing helical screws, known as rotors, to compress the gas. In a dry-running rotary-screw compressor, timing gears ensure that the male and female rotors maintain precise alignment without contact which would produce rapid wear. In an oil-flooded rotary-screw compressor, lubricating oil bridges the space between the rotors, both providing a hydraulic seal and transferring mechanical energy between the rotors, allowing one rotor to be entirely driven by the other. Gas enters at the suction side and moves through the threads as the screws rotate.

The automotive industry requires lightweight metal matrix materials with improved friction and wear resistance to achieve significant weight reductions and improve fuel efficiency of vehicles. Cylinder liners, pistons, bearing surfaces (including wind energy equipment and compressors), cam shaft tappets, lifters, rockers, brake components) are examples of the use of new low cost and lightweight self lubricating composites developed at UWM. These composites contain solid lubricants like graphite dispersed in metals like Aluminum, Magnesium and Copper to reduce frictional energy loss. In addition these composites can run under boundary lubrication in the event of loss of lubricant.

Because medications have been linked to approximately 22% to 28% of all cases of dysgeusia, researching a treatment for this particular cause has been important. Xerostomia, or a decrease in saliva flow, can be a side effect of many drugs, which, in turn, can lead to the development of taste disturbances such as dysgeusia. Patients can lessen the effects of xerostomia with breath mints, sugarless gum, or lozenges, or physicians can increase saliva flow with artificial saliva or oral pilocarpine. Artificial saliva mimics the characteristics of natural saliva by lubricating and protecting the mouth but does not provide any digestive or enzymatic benefits.

Northern Pacific Railroad Shops Inside a diesel shed Old railway depot in Suonenjoki, Finland The motive power depot (MPD or railway depot) is the place where locomotives are usually housed, repaired and maintained when not being used. They were originally known as "running sheds", "engine sheds" or, for short, just sheds. Facilities are provided for refuelling and replenishing water, lubricating oil and grease and, for steam engines, disposal of the ash. There are often workshops for day to day repairs and maintenance, although locomotive building and major overhauls are usually carried out in the locomotive works.

The earlier engines required the ignitors to be inserted through holes in the engine into the combustion chamber, but the new system allowed the fuel to be sprayed into the main injector. The fuel, triethylaluminum, was delivered in a cube with diaphragms that burst when the fuel flow in the injector reached a set threshold. Finally, the X-1 introduced a new lubrication system that added a small amount of additive to the RP-1 fuel as it flowed through the various components. This was fed under pressure into the various bearings in the turbopump system, both lubricating it and carrying away heat.

Typically, a sliding ski melts a thin and transitory film of lubricating layer of water, caused by the heat of friction between the ski and the snow in its passing. Colbeck suggests that the optimum water film thickness is in the range between 4 and 12 μm. However, the heat generated by friction can be lost by conduction to a cold ski, thereby diminishing the production of the melt layer. At the other extreme, when the snow is wet and warm, heat generation creates a thicker film that can create increased capillary drag on the ski bottom.

Ganson describes his work as a cross between mechanical engineering and choreography. His sculptures have been called "gestural, humorous, evocative, and introspective", or "Ingenious. Philosophical. Witty". Some of his extremely elaborate machines have one very simple function, such as elegantly anointing themselves with lubricating oil scooped up from a pan (Machine with Oil), or causing a chair to chaotically bounce around a toy cat (Margot's Other Cat). Other machines do nothing at all but move in a visually fascinating manner, such as a toy chair that suddenly assembles from small sticks and planks of wood (Cory's Yellow Chair).

The two-piece crankshaft, with counter-weights, is carefully forged from heat-treated chrome-vanadium alloy steel and drilled for lightness and lubricating oil flow. Master and slave connecting rods are forged and machined from the same material as the crank-shaft. The rear of the crankshaft carries an induction rotor to ensure even mixture distribution to the cylinders from the Stromberg carburettor. The two-piece crankcase is split in the plane of the cylinder centres, with the forward half supporting the fwd crank /prop-shaft bearing and the rear half housing the rear bearing, induction rotor, cam drives and accessories.

He was educated at County High School, Ilford, at South East Essex Technical College and at Birkbeck College. His degrees of B.Sc., Ph.D. and D.Sc. were all obtained by part-time study. On leaving school in 1937 Bonnor served in clerical and executive branches of the Civil Service until 1944, when he became a chemist in the Admiralty, doing development work in paint technology. In 1946 he joined Shell Refining and Marketing Company to work on the rheology of lubricating greases. His career as a mathematician commenced in 1949 after obtaining a degree in mathematics at Birkbeck College.

For the bow, the only real maintenance is regular cleaning of the stick with a cloth (to remove rosin dust), re-hairing, and replacing the leather and silver wire wrapping. In the course of playing, hairs are often lost from the bow, making it necessary to have it rehaired periodically, which is done by professionals at roughly the cost of a new set of strings. Other maintenance may include replacing the wire lapping and leather grip or lubricating the screw. Large cracks and breakages in the bow are usually fatal; they cannot be repaired like the body of the violin can.

During her ensuing overhaul, she received a bathythermograph and a high periscope. Saury returned to Pearl Harbor on 16 April 1943 and, on 7 May, she departed for her sixth war patrol which would take her into the East China Sea to operate off the northern Ryukyu Islands and in the coastal waters of Kyūshū. During the patrol, she would also test the effectiveness of the high periscope in daytime attacks and the usefulness of the bathythermograph in locating thermal layers in which to hide. On 11 May, Saury topped off on fuel and lubricating oil at Midway Island, then continued west.

Alternately, the skewer was dipped in boiling oil, which served a dual purpose of both burning the incredibly sensitive flesh and lubricating the needle so that the torturer could freely explore a wide surface area beneath the toenail. When enough skewers had been driven home to pry each nail loose from its bed, the nail was torn out at the root with a pair of pliers. This was a favorite technique of torture in the German witch-hunter's arsenal, being extremely inexpensive, portable, and easy to inflict. More recently, the denailing torture found favorite application during the Armenian genocide of the 1910s.

To reduce the aircraft's weight, no firewall had been provided, and the aft end of each DB 606 was fitted so close to the main spar — with the rear two-thirds of the component powerplants' engine blocks being placed behind the wing's leading edge — that there was insufficient space for the fuel/oil fluid lines and electrical harnesses. The engines' exterior surfaces within the cowlings were frequently saturated with fuel and oil from leaking connections. At high altitude the oil tended to foam due to a badly designed oil pump,Price 2004, p. 162. reducing its lubricating qualities.

The faster classes of PRO hydroplanes (with straightaway speeds from around 75 to 120 miles per hour) use 2-cycle outboard motors running highly filtered methanol race fuel mixed with a pure castor or synthetic castor-based lubricating oil. All methanol-fueled and gasoline-fueled PRO racing outboard motors are direct drive (no gear reduction) and equipped with high performance, motorcycle racing style magneto ignition and carburetor systems. 125cc through 1000cc PRO series hydroplanes are not entry level classes in outboard powerboat racing. Investment costs are moderately high compared to similar APBA stock and modified outboard racing classes.

She was one of a large fleet of all wooden boats used by that Company for liquid cargo carrying, the main hold area being fully decked over. When new it would have carried refined fuels such as gas oil for powering machinery but as it got older it was used for carrying heavier lubricating oil from the fuel distribution plants on the Manchester Ship Canal. It is now owned by the Black Country Living Museum, in Dudley, where it is based and can be seen dockside in the Lord Ward's Canal Arm at the museum. Stour is on the National Historic Ships register.

The Latin anatomical name is tunica serosa. Serous membranes line and enclose several body cavities, known as serous cavities, where they secrete a lubricating fluid which reduces friction from muscle movement. Serosa is entirely different from the adventitia, a connective tissue layer which binds together structures rather than reducing friction between them. The serous membrane covering the heart and lining the mediastinum is referred to as the pericardium, the serous membrane lining the thoracic cavity and surrounding the lungs is referred to as the pleura, and that lining the abdominopelvic cavity and the viscera is referred to as the peritoneum.

In this arrangement, one side of the motor housing is supported by plain bearings riding on a ground and polished journal that is integral to the axle. The other side of the housing has a tongue- shaped protuberance that engages a matching slot in the truck (bogie) bolster, its purpose being to act as a torque reaction device, as well as a support. Power transfer from motor to axle is effected by spur gearing, in which a pinion on the motor shaft engages a bull gear on the axle. Both gears are enclosed in a liquid-tight housing containing lubricating oil.

Hunger brought about Germany's collapse, and the vivid memories of the time of deprivation led to the rise of the Nazi Party led by Adolf Hitler. During the inter-war years, Nazi Germany used a frugal "guns or butter" policy, with food producers ordered to assist the war aims of the Nazi government. New uses for food products included fat as a component for high explosives, apples to be turned into synthetic fuel and milk made into lubricating oil. German scientists created other synthetic items include a soy substitute for meat, with the purpose of making the nation self-sufficient in food.

Extract of Ricinus communis exhibited acaricidal and insecticidal activities against the adult of Haemaphysalis bispinosa Neumann (Acarina: Ixodidae) and hematophagous fly Hippobosca maculata Leach (Diptera: Hippoboscidae). Members of the Bodo tribe of Bodoland in Assam, India, use the leaves of the plant to feed the larvae of muga and endi silkworms. Castor oil is an effective motor lubricant and has been used in internal combustion engines, including those of World War I airplanes, some racing cars and some model airplanes. It has historically been popular for lubricating two-stroke engines due to high resistance to heat compared to petroleum-based oils.

The Dash 8-40CM is powered by a V16 7FDL diesel engine driving a GE GMG187 main alternator. The power generated by the main alternator drives six GE 752AG or 752AH direct current traction motors, each with a gear ratio of 83:20 and connected to wheels which allow the Dash 8-40CM a maximum speed of 70 mph (110 km/h). Depending on customer options, the Dash 8-40CM carries approximately of diesel fuel, of lubricating oil, and of coolant. Like most North American diesel locomotives, the Dash 8-40CM uses normal water for cooling.

Water vapor is removed from compressed air to prevent condensation from occurring and to prevent moisture from interfering in sensitive industrial processes. Excessive liquid and condensing water in the air stream can be extremely damaging to equipment, tools and processes that rely on compressed air. The water can cause corrosion in the tank(s) and piping, wash out lubricating oils from pneumatic tools, emulsify with the grease used in cylinders, clump blasting media and fog painted surfaces. Therefore, it is desirable to remove condensing moisture from the air stream to prevent damage to equipment, air tools and processes.

Recognizing the potential of the fledgling oil industry, in the late 1860s Miller moved to Franklin, Pennsylvania and organized the Galena Oil Company in partnership with his brother in law Joseph C. Sibley. This venture, which eventually became the Galena-Signal Oil Company, played a key role in replacing animal-fat based lubricants in business and industry, and grew to become the primary supplier of lubricating oil to the railroad industry. He served as the company president until 1919. Galena-Signal eventually became a Standard Oil subsidiary, and then part of the conglomerates now known as Texaco (1928) and Valvoline (1931).

The treatment of fecal impaction requires both the remedy of the impaction and treatment to prevent future recurrences. Decreased motility of the colon results in dry, hard stools that in the case of fecal impaction become compacted into a large, hard mass of stool that cannot be expelled from the rectum. Various methods of treatment attempt to remove the impaction by softening the stool, lubricating the stool, or breaking it into pieces small enough for removal. Enemas and osmotic laxatives can be used to soften the stool by increasing the water content until it is soft enough to be expelled.

Hypoid gears are stronger, operate more quietly and can be used for higher reduction ratios, however they also have some sliding action along the teeth, which reduces mechanical efficiency, the energy losses being in the form of heat produced in the gear surfaces and the lubricating fluid. In older automotive designs, hypoid gears were typically used in rear-drive automobile drivetrains, but modern designs have tended to substitute spiral bevel gears to increase driving efficiency. Hypoid gears are still common in larger trucks because they can transmit higher torque. A higher hypoid offset allows the gear to transmit higher torque.

However, the alliance was able to monopolize various markets so successfully because it adopted the M-form system, which allowed the firm to act as a loose federation of autonomous units instead of just one giant firm. Although central management provided a general direction for the alliance as a whole, each arm was able to act individually to pursue what would maximize each division's success. Furthermore, even though the alliance's lubricating oil business did not keep pace, since this was an autonomous division under the M-form system of management, it did not have detrimental consequences for the overall alliance.

Official Souvenir Programme, 1977. Silver Jubilee Fleet Review, HMSO In 1979, she was attached to the Clyde division of the RNR, while later that year, she transferred to the Fishery Protection Squadron. On 21 June 1979, the commercial tanker Tarpenbek, carrying a load of lubricating oil, collided with the landing ship off Selsey Bill in thick fog, holing the tanker. Hodgeston went to the assistance of Tarpenbek, and when the tanker capsized in heavy seas, helped to co-ordinate with salvage vessels, which managed to recover the oil, preventing major ecological damage, and salvaged the tanker, righting her by Parbucking.

The o-ring chain is named for the rubber o-rings built into the space between the outside link plate and the inside roller link plates. Chain manufacturers began to include this feature in 1971 after the application was invented by Joseph Montano while working for Whitney Chain of Hartford, Connecticut. O-rings were included as a way to improve lubrication to the links of power transmission chains, a service that is vitally important to extending their working life. These rubber fixtures form a barrier that holds factory applied lubricating grease inside the pin and bushing wear areas.

However, because of its high price, h-BN was soon abandoned for this application. Its use was revitalized in the late 1990s with the optimization h-BN production processes, and currently h-BN is used by nearly all leading producers of cosmetic products for foundations, make-up, eye shadows, blushers, kohl pencils, lipsticks and other skincare products. Because of its excellent thermal and chemical stability, boron nitride ceramics are traditionally used as parts of high-temperature equipment. h-BN can be included in ceramics, alloys, resins, plastics, rubbers, and other materials, giving them self-lubricating properties.

Propane lacks additives, detergents or other chemical enhancements further reducing the exhaust output from the tailpipe. The cleaner combustion also has fewer particulate emissions, lower NOx due to the complete combustion of the gas within the cylinder, higher exhaust temperatures increasing the efficiency of the catalyst and deposits less acid and carbon inside the engine which extends the useful life of the lubricating oil. Propane autogas is generated at the well alongside other natural gas and oil products. It is also a by-product of the refining processes which further increase the supply of Propane to the market.

Off-highway construction equipment from excavators to simple loaders employs hydraulic transmission systems as a primary source of motion. Hydraulic piston pumps, mechanical devices used to convert mechanical energy into hydraulic energy, are typically used in off-highway construction equipment and driven by an electric motor or a combustion engine. Bearings are mounted on the piston pump shaft, which transfers drive torque to the cylinder block. The bearing's role is to ensure smooth movement and reduce energy use. Composite bearings’ self- lubricating PTFE layer allows consistent, low friction in pump mechanisms for minimal energy use and reduced maintenance requirements.

The camera's precision-tapered, high-strength vertical metal shutter blades were fabricated originally of lightweight titanium (later production FM2 shutter blades were made of aluminum), while the mirror/shutter mechanism rides on self- lubricating bearings. The mirror linkage uses the same mechanism found on Nikon's professional F2, with some modern improvements designed to further reduce effects of vibration and mirror bounce. The FM2 also features Nikon's close tolerance assembly and minimal space lubrication, meaning that it will reliably operate in temperature extremes of −40 °C to +50 °C. The Nikon FM2 in black.

Control rods are a series of rods that can be quickly inserted into the reactor core to absorb neutrons and rapidly terminate the nuclear reaction. They are typically composed of actinides, lanthanides, transition metals, and boron, in various alloys with structural backing such as steel. In addition to being neutron absorbent, the alloys used also are required to have at least a low coefficient of thermal expansion so that they do not jam under high temperatures, and they have to be self-lubricating metal on metal, because at the temperatures experienced by nuclear reactor cores oil lubrication would foul too quickly.

Otherwise the chain might derail. The underside of each link features a small metal finger called a "drive link" (also DL) which locates the chain on the bar, helps to carry lubricating oil around the bar, and engages with the engine's drive sprocket inside the body of the saw. The engine drives the chain around the track by a centrifugal clutch, engaging the chain as engine speed increases under power, but allowing it to stop as the engine speed slows to idle speed. Consistent improvement to overall chainsaw design, including adding safety features, have taken place over the years.

Internal combustion engines often use a timing chain to drive the camshaft(s). This is an area in which chain drives frequently compete directly with timing belt drive systems, particularly when the engine has one or more overhead camshafts, and provides an excellent example of some of the differences and similarities between the two approaches. For this application, chains last longer, but are often harder to replace, as they must be enclosed in a space into which lubricating oil can be introduced. Being heavier, the chain robs more power, but is also less likely to fail.

One of the primary users of the new Norwegian polar research vessel is the Nansen Legacy project which will include over 370 ship-days by 2020 primarily on Kronprins Haakon.Nansen Legacy Project In addition, the vessel will regularly sail to the Antarctic. In July 2019, one of Kronprins Haakons propulsion units developed a lubricating oil leak during icebreaking operations north of Svalbard, forcing the research vessel to cancel a scientific cruise ahead of schedule and return to Norway for repairs. During inspection in Harstad, the cause of the leak was discovered to be a loose bolt in the port side propeller shaft seal.

The filter paper is used only once. If only the liquid is of interest, the paper is discarded; if the suspension is of interest, both the solid residue and non-polar liquids, such as oil, may clog of polyethylene or galvanized steel and using a brass or plastic mesh filter, are typically for automotive and workshop use, to filter debris from fuel, lubricating oil and coolant. The screen is reusable, and may be cleaned by inverting the funnel and tapping it on a hard surface, or popping it out and washing it separately. This helps to avoid spilling any liquids.

Neely said he only realized afterwards that the medic had him move to a point where Neely's body blocked the medics punches from the guards in the guard tower. He said later learned that the captive resisted drinking the diet supplement because he feared it was poisonous. Neely said that he saw camp medical staff perform a digital rectal examination, searching for contraband, without first lubricating their fingers, and that this made the captive scream in pain. Neely said that it had been a friend of his who was the first guard the captives saw drop a Qur'an on the ground.

As a result of radiotherapy to the mouth, radiation-induced stomatitis may develop, which can be associated with mucosal erosions and ulceration. If the salivary glands are irradiated, there may also be xerostomia (dry mouth), making the oral mucosa more vulnerable to frictional damage as the lubricating function of saliva is lost, and mucosal atrophy (thinning), which makes a breach of the epithelium more likely. Radiation to the bones of the jaws causes damage to osteocytes and impairs the blood supply. The affected hard tissues become hypovascular (reduced number of blood vessels), hypocellular (reduced number of cells), and hypoxic (low levels of oxygen).

Boyer has done things from extracting lubricating and paint oils from the soybean to creating a synthetic wool made from soybeans and pressing insulating varnish for starters and generators (Plastic). One of Boyer’s first projects began in 1932 and included building “a small solvent extractor to separate the bean into soy oil and protein-rich meal” (Shurtleff). The soybean oil became the most crucial commercial soy products on Ford cars. In 1934 the five to eight coats of lacquer that cars previously had been finished with was replaced with a synthetic baked enamel paint which contained about 35% soy oil.

As the salivary glands produce fluid and carbohydrate-digesting enzymes (mostly amylases), strong muscles in the pharynx pump fluid into the buccal cavity, lubricating the food like the salivarium does, and helping blood feeders, and xylem and phloem feeders. From there, the pharynx passes food to the esophagus, which could be just a simple tube passing it on to the crop and proventriculus, and then onward to the midgut, as in most insects. Alternately, the foregut may expand into a very enlarged crop and proventriculus, or the crop could just be a diverticulum, or fluid-filled structure, as in some Diptera species.

Researchers tested more than 200 U.S. vehicles of model years 2011–2012 for chemicals such as organobromine compounds (associated with brominated flame retardants, or BFRs), organochlorine compounds (e.g., polyvinyl chloride, or PVC), and heavy metals that off-gas from various parts such as the steering wheel, dashboard, armrests and seats. Some recommend keeping new cars well ventilated while driving, especially during the summer. A 1995 analysis of the air from a new Lincoln Continental found over 50 volatile organic compounds, which were identified as coming from sources such as cleaning and lubricating compounds, paint, carpeting, leather and vinyl treatments, latex glue, and gasoline and exhaust fumes.

Deliberate non-penetrative sex without vaginal sex or deliberate oral sex without vaginal sex are also sometimes considered birth control. While this generally avoids pregnancy, pregnancy can still occur with intercrural sex and other forms of penis-near-vagina sex (genital rubbing, and the penis exiting from anal intercourse) where sperm can be deposited near the entrance to the vagina and can travel along the vagina's lubricating fluids. Abstinence-only sex education does not reduce teenage pregnancy. Teen pregnancy rates and STI rates are generally the same or higher in states where students are given abstinence-only education, as compared with comprehensive sex education.

The locomotive has the 1Co- Co1 wheel arrangement and is carried on two cast steel bogies, each having three driving axles guided at the outer end by a Bissel truck. The locomotive superstructure has a semi-streamlined appearance with a cab behind each nose end compartment. Between the two cabs is the engine compartment, within which the radiators, the power unit and the control cubicle are mounted. The radiators for the cooling water and lubricating oil are located one on each side of the locomotive and are cooled by a roof mounted fan, driven directly from the engine through cardan shafts and a gearbox.

Fiat 128 Special Front-wheel drive had previously been introduced to small, inexpensive cars by BMC, firstly with the Mini in 1959 and then with the larger 1100/1300 series in 1962. During the mid-1960s, Fiat set about designing a new car to compete with the latter. The BMC design of Alec Issigonis had the transmission and engine sharing a single oil sump -- despite disparate lubricating requirements -- and located the engine's radiator at the side of the engine, away from the flow of fresh air and drawing heated rather than cool air over the engine. The layout often required the engine to be removed to service the clutch.

Most small petrol two-stroke engines cannot be lubricated by oil contained in the crankcase and sump, as the crankcase is being used to pump fuel-air mixture into the cylinder. Over a short period, the constant stream of fuel-air mixture would carry the lubricating oil to the combustion chamber, while thinning the remainder with condensing petrol. Traditionally, the moving parts (both rotating crankshaft and sliding piston) were lubricated by a fuel-oil mixture (at a ratio between 16:1 and 100:1). Two-stroke oils, which became available in the 1970s, are specifically designed to mix with petrol and be burnt with minimal unburnt oil or ash.
|
|
As two-stroke engines use their crankcase to pressurize the air:fuel mixture before transfer to the cylinder, any standard lubricating oil left there (per practice with four-stroke engines) would be swept up and burnt with the fuel. To provide cylinder lubrication, fuels supplied to two-stroke engines are often mixed with oil so that it can coat the cylinders and bearing surfaces along its path. The ratio of gas to oil is set by the engine manufacturer but ranges from 30:1 to 50:1 per volume unit. Oil remaining in the mixture is burnt with the fuel and results in a familiar blue smoke and odor.

First Lieutenant Doug Craig In evaluating how to strike back at the Japanese, RAAF intelligence knew that half of all lubricating oils used by the Japanese military and 60 percent of all their aviation fuel came from refineries in Borneo. The target was hundreds of miles behind enemy lines which some believed would be impossible to reach. After carrying out many long-range test flights using newly developed cruise techniques to increase range, the mission was approved. Carrying a crew of 10 and one RAAF photographer, Shady Lady was one of eleven bombers that followed the setting sun westward on August 13, past Timor into heavily defended enemy territory.

Besides lubricating the moving parts of the valve, valve oil provides corrosion protection to the bare metal of the inner valve. While the valve piston or rotor is made of a metal which is more resistant to corrosion, the inner valve casing is typically bare brass. (The brass on the outside of a modern instrument is lacquered or plated to prevent corrosion.) The oil also completes the seal between the valve casing and the piston or rotor. Although a clean and unoiled valve of a well maintained instrument should move without unusual force, the inside of a musical instrument is a very inhospitable environment for a delicate valve mechanism.

In line with her original Canadian Arctic Shipping Pollution Prevention Regulations (CASPPR) Arctic Class 4 rating, Vladimir Ignatyuk is designed to break at least first-year level ice with a continuous speed of . During icebreaking operations, the ice friction is reduced by lubricating the hull-ice interface with a low-pressure air bubbling system developed by Wärtsilä. In open water, the system can also act as a bow thruster and used for maneuvering together with the ship's single centerline rudder and a transverse stern thruster. When operating in ice-free waters, the ship can transit at an economical speed of about with just two main engines.

It is detectable by the presence of a black ooze around the exhaust manifold, piping and turbocharger, if fitted. It can be mistaken for lubricating oil in some cases, but it consists of the "heavy ends" of the diesel fuel which do not burn when combustion temperature is too low. The heavier, more oily components of diesel fuel contain more stored energy than a comparable quantity of, say, gasoline, but diesel requires an adequate loading of the engine in order to keep combustion temperature high enough to make use of it. Often, one can hear a slight miss in the engine due to fuel buildup.

High-speed steel twist bit drilling into aluminium with methylated spirits lubricant Under normal usage, swarf is carried up and away from the tip of the drill bit by the fluting of the drill bit. The cutting edges produce more chips which continue the movement of the chips outwards from the hole. This is successful until the chips pack too tightly, either because of deeper than normal holes or insufficient backing off (removing the drill slightly or totally from the hole while drilling). Cutting fluid is sometimes used to ease this problem and to prolong the tool's life by cooling and lubricating the tip and chip flow.

A roughing pump is any vacuum pump (typically mechanical) used to initially evacuate a vacuum system, as a first stage towards achieving high vacuum or ultra high vacuum. The term "roughing pump" derives from the vacuum range it works in, "rough vacuum", above 1x10−3 torr (0.1 Pa). Pumps that operate in the high vacuum ranges typically don't operate, or only operate inefficiently, at atmospheric pressures, whereas pumps that work efficiently at atmospheric pressure usually cannot produce a vacuum lower than approximately 1x10−3 torr. One consideration for choosing a roughing pump is whether the pump uses lubricating oil that's exposed to the vacuum.

The Dash 8-40CW is powered by a V16 7FDL diesel engine driving a GE GMG187 main alternator. The power generated by the main alternator drives six GE 752AG or 752AH Direct Current traction motors, each with a gear ratio of 83:20 and connected to wheels which allow the Dash 8-40CW a maximum speed of . Depending on customer options, the Dash 8-40CW carries approximately 5000 US gallons (18927 L) of diesel fuel, 410 US gal (1,552 L) of lubricating oil, and 380 gallons (1,438 L) of coolant. Like most North American diesel locomotives, the Dash 8-40CW uses normal water for cooling.

Personnel and equipment required to get and keep a B-36 aircraft in the air The Wasp Major engines had a prodigious appetite for lubricating oil; each engine required a dedicated 100-gal (380-l) tank. Normal maintenance consisted of tedious measures, such as changing the 56 spark plugs on each of the six engines; the plugs were often fouled by the lead in the 145 octane antiknock fuel required by the R-4360 engines. Thus, each service required changing 336 spark plugs. Another frequent maintenance job was replacing the dozens of bomb bay light bulbs, which routinely shattered during test firing of the turret guns.

A sebaceous gland is a microscopic exocrine gland in the skin that opens into a hair follicle to secrete an oily or waxy matter, called sebum, which lubricates the hair and skin of mammals. In humans, sebaceous glands occur in the greatest number on the face and scalp, but also on all parts of the skin except the palms of the hands and soles of the feet. In the eyelids, meibomian glands, also called tarsal glands, are a type of sebaceous gland that secrete a special type of sebum into tears. Surrounding the female nipple, areolar glands are specialized sebaceous glands for lubricating the nipple.

A personal lubricant can be used to increase pleasure and reduce pain during sexual intercourse or other activities and may be used for lubricating the penis, vagina, anus, stroker or dildo or other sex toys before or during activity. Lubricant may be applied to any body part desired, to the inside and/or outside of condoms, or to the hands or fingers. Personal lubricants are particularly useful for intercourse when a partner experiences dryness or excessive contraction (tightness) of the vagina or anus. Anal sex generally requires more generous application of lubricant since the anus does not have natural lubrication sufficient for most sexual activity.

Although the cannon of ships of the line were protected as they were retracted inside the ships, many smaller vessels had exposed gundecks which required a plug to protect inside of the barrels. To combat rust when ships were not in action the barrels were sealed, both with a tampion and plugs in the touch hole. A quantity of olive oil and a round shot were left inside in the barrel; With the gun laid horizontally the shot would roll up and down the barrel as the ship caught each wave, effectively lubricating the gun simply through the motion of the ship.Morris, 2006, p. 110.

To support the planned global war on the high seas against Britain, Raeder planned to get around the problems posed by the lack of bases outside of Germany by instructing naval architects to increase the range and endurance of German warships and build supply ships to re-supply German raiders on the high seas.Hansen pp. 95–96 and 99–101. In 1936, Raeder ordered a new class of support ships, the ships, which served as a combined oil tanker-supply ship- hospital ship-repair shop and could carry 9,000 tons of fuel oil and 4,000 tons of lubricating oil plus ammunition, water, spare parts and food.

Nigerian locomotives had cow catchers and ABC couplers, Ghanaian locomotives had Visco No 2 Alliance couplers. The hood comprised a compartment housing the water and oil cooling radiators and the fan; a motor blower group for the traction motors along with its own air filters; and a motor driven air compressor with suction strainer, and an air reservoir. Air for the electro-pneumatic control gear, sanding, window wipers and emergency refuelling of the locomotives, was supplied from this system. The second compartment in the main casing contained the main engine and generator with the main air intake-air filters and the lubricating oil filters.

Two anecdotes about the windmill appear in a 1933 book, which refers to it as the Jaffa Gate Mill. The first is that there was much opposition from among the local millers to the windmill, who looked upon it with the evil eye and sent their head man to curse it. Predictions were made that the mill would be washed away during the rainy season; after it survived intact, it was declared to be the work of Satan. The second is that the Arabs developed a taste for the lubricating oil on the bearings and would lick them, prompting fear the mill would burn down from the resulting friction.

Kroonlands lifeboat, manned by a fresh crew, headed back out and returned with 13 steerage passengers. On board Volturno, the crew and some of the male passengers, unable to extinguish the fire, were at least able to keep it from spreading to the aft cargo holds, over which the others on board were gathered. Shortly before dawn, a large explosion—probably of her boilers—rocked Volturno, and the rescuers felt that the ship, which had not been in imminent danger of sinking up to this point, might founder at any time. The tanker Narragansett turned on her pumps and sprayed lubricating oil on the sea to help calm the surface.

The plant is situated along the Saugus River, along railroad tracks. The factory was built in 1943 as a supercharger facility, and helped to build the first jet engine during World War II. Activities performed at the plant originally included aircraft engine testing, disassembly, lubricating, cleaning and assembly. Operations included, degreasing, electrochemical grinding, engine maintenance, metal washing, parts cleaning and stress fracture testing. From 1968 to 1972, the ‘Pilot Program’ was introduced. Faced with rising tensions on the shop floor, bottle-necks in production and low- quality products, GE management tried a scheme of workers’ control of production in one area of the plant.

The adsorption of lubricin to cartilage surfaces occurs through interactions on its N- and C- terminus, where its bottle brush structure plays a role in both coating and repelling similarly coated cartilage surfaces due to steric repulsion. Lubricin's high degree of hydration is also thought to be involved in repulsion forces generated by lubricin between opposing cartilage surfaces. Shear studies of lubricin adsorbed between various hydrophilic and hydrophobic surfaces have confirmed the importance of the glycoprotein in boundary lubrication and wear protection in articular joints. Lubricin's bottle brush structure is common among a number of human lubricating glycoproteins, and a number of studies have been conducted to mimic this.

During the 1970s and 1980s as the dynamics of the United States petroleum industry were changing, the refinery was transformed to produce higher-value, higher-volume fuels and lubricating oils and to comply with increasingly stringent state and federal policies. These policies called for the refinery to reduce air emissions and waste, treat water, and prevent oil spills. In order to comply with federal mandates for reduced-lead gasoline the refinery installed reforming units in 1971 to produce higher octane gasoline material. In 1975, the refinery added a desulfurization unit for the production of low-sulfur fuel oil, primarily to supply the growing needs of California electric utility companies.

Small oil application device for Singer sewing machines Cycle oil is a light lubricating oil suited for use on bicycles and similar devices. It is a liquid residue produced in the petroleum industry when catalytic cracking is employed to convert heavy hydrocarbon fractions remaining from earlier stages of crude oil refining into more valuable lighter products. Catalytic cracking produces petrol (gasoline), liquid petroleum gas (LPG), unsaturated olefin compounds, cracked gas oils, cycle oil, light gases and a solid coke residue. Cycle oil may be processed further to break it down into more useful products; in particular it may be mixed with heavier products and put through the refining process again (recycled).

The serous pericardium, in turn, is divided into two layers, the parietal pericardium, which is fused to and inseparable from the fibrous pericardium, and the visceral pericardium, which is part of, or in some textbooks synonymous with, the epicardium. Both of these layers function in lubricating the heart to prevent friction during heart activity. The visceral layer extends to the beginning of the great vessels (the large blood vessels serving the heart) becoming one with the parietal layer of the serous pericardium. This happens at two areas: where the aorta and pulmonary trunk leave the heart and where the superior vena cava, inferior vena cava and pulmonary veins enter the heart.

But on smaller reduction drives attached to auxiliary machinery or if the design of the ship demands it, one can find thrust bearings as a part of the assembly. In order to ensure a reduction drive's smooth working and long lifetime, it is vital to have lubricating oil. A reduction drive that is ran with oil free of impurities like water, dirt, grit and flakes of metal, requires little care in comparison to other type of engine room machinery. In order to ensure that the lube oil in the reduction gears stay this way a lube oil purifier will be installed with the drive.

Reaching recently secured Tanapag Harbor on 17 July 1944, Yakutat began setting up a seaplane base there and immediately commenced servicing seaplanes, providing subsistence and quarters for the aviators and aircrews attached to those aircraft. She provided the aircraft with gasoline and lubricating oil via bowser fueling boats and commenced servicing planes by the over-the-stern method as well. Yakutat remained at Tanapag Harbor for the rest of July, all of August, and into September 1944. After shifting to the Garapan anchorage on Saipan on 8 September 1944, she transferred all plane personnel to the seaplane tender and sailed for the Palau Islands on 12 September 1944.

Spin-on oil filter, showing annular seal and screw-on thread Saab New (left) and used (right) motorcycle oil filters An oil filter is a filter designed to remove contaminants from engine oil, transmission oil, lubricating oil, or hydraulic oil. Their chief use is in internal-combustion engines for motor vehicles (both on- and off-road ), powered aircraft, railway locomotives, ships and boats, and static engines such as generators and pumps.. Other vehicle hydraulic systems, such as those in automatic transmissions and power steering, are often equipped with an oil filter. Gas turbine engines, such as those on jet aircraft, also require the use of oil filters. Oil filters are used in many different types of hydraulic machinery.

For a time he was the sole tradesman operating in Richmond. After his regiment was mustered out in November 1865 Nye returned to New Bedford and began developing the lubricant oil business for which he became principally known. Nye's oil business, originally run out of small rented premises in Fairhaven, focused primarily on highly refined lubricant oils for watches, clocks, typewriters, sewing machines, and bicycles. In the late 1860s he acquired an entire catch of 2,200 pilot whales which would supply the raw material for his lubricating oils for several years. He expanded the business in 1877 with the purchase of a large brick building on Fish Island which became its principal refinery.

Royal Australian Air Force (RAAF) intelligence determined that half of all lubricating oils used by the Japanese military and 60 percent of all their aviation fuel came from refineries in Balikpapan, and it was therefore an extremely important target. The American 380th Bombardment Group under the command of the RAAF, including the famous B-24 Liberator Shady Lady, attacked the oil refineries in August 1943 from Darwin, Australia. Amazingly, there were no aircraft losses, despite the crash landing and subsequent repair of the Shady Lady. In September and October 1944, the 5th and 13th Air Forces under the command of General George Kenney launched a series of five raids from Noemfoor Island.

Staying dry may keep the skin from the developing further chafing, although this can be next to impossible in hot weather and requires avoiding exercise. After the workout, you must take a bath daily because sweat will evaporate and its salt causes chafing or you can use certain products such as baby powder, potato flour or antiperspirant may help with keeping the problem areas dry. An alternative to staying dry is lubricating the skin with petroleum jelly or other lubricants in order to reduce the friction and allow the body parts to glide without forming a rash. In many cases, however, especially those involving the upper thighs, clothing is the biggest culprit.

This tree is one of two species which yield the valuable Lignum vitae wood, the other being Guaiacum officinale. The wood has been used for making specific parts of ships that needed to be self-lubricating so that they would last longer. The tree is considered to have medicinal value, used mostly for home remedies. The naturalist William Turner noted in 1568 that the plant was already being grown in India, Tamraparni (ancient Sri Lanka), Java and the Tivu islets of the ocean, and whose broth cured several harsh diseases, including French pox (Syphilis).MUNGER, ROBERT S. “Guaiacum, the Holy Wood from the New World.” Journal of the History of Medicine and Allied Sciences, vol.

The Lohmann kit utilized a two-cycle compression-ignition engine, and was designed to run off of a light distillate mixed with a measured amount of lubricating oil. It is considered to be a diesel engine in the sense that it is a compression ignition design without a spark plug, but does not use an injection pump or fuel injection as does a conventional diesel engine. In France, where postwar reconstruction, taxes, and fuel shortages limited automobile access, motorized bicycle kits and complete models were produced by a variety of smaller manufacturers, often using a two-stroke gasoline engine mounted above the front wheel. In 1946, production of the very successful French VELOSOLEX commenced, continuing until 1988.

The investigation then proceeded to examine why scheduled maintenance had failed to adequately lubricate the jackscrew assembly. In interviews with the Alaska Airlines mechanic at San Francisco International Airport (SFO) who last performed the lubrication it was revealed that the task took about one hour, whereas the aircraft manufacturer estimated the task should take four hours. This and other evidence suggested to the NTSB that "the SFO mechanic who was responsible for lubricating the jackscrew assembly in September 1999 did not adequately perform the task". Laboratory tests indicated that the excessive wear of jackscrew assembly could not have accumulated in just the four-month period between the September 1999 maintenance and the accident flight.

For integral membrane proteins spanning the thickness of the membrane bilayer, these annular/shell lipids may act like a lubricating layer on the proteins' surfaces, thereby facilitating almost free rotation and lateral diffusion of membrane proteins within the 2-dimensional expanse of the biological membrane(s). Outside the layer of shell/annular lipids, lipids are not tied down to protein molecules. However, they may be slightly restricted in their segmental motion freedom due to mild peer pressure of protein molecules, if present in high concentration, which arises from extended influence of protein-lipid interaction. Membrane areas away from protein molecules contain lamellar phase bulk lipids, which are largely free from any restraining effects due to protein-lipid interactions.

From the title of the piece, Technical Ecstasy, I thought of something ecstatic rather than something technical, and I immediately thought of ecstasy in sexual terms: some sort of mechanical copulation, which would be tricky to do. I then thought of ecstasy as falling in love, perhaps during a brief encounter on an escalator – and, since it was 'technical', I thought of two robots ... It's really quite simple – he's just done curves for the female and hard, angular, macho lines for the male. It's really quite sexist, actually – stereotyped. Anyway, it's love at first sight, but I felt robots wouldn't do it like humans would do it, so instead they're squirting lubricating fluid at one another.

The resolved components appear as peaks while the UCM appears as a large background/platform. In non-biodegraded oils the UCM may comprise less than 50% of the total area of the chromatogram, while in biodegraded oils this figure can rise to over 90%. UCMs are also observed in certain refined fractions such as lubricating oils and references therein. One reason why it is important to study the nature of UCMs is that some have been shown to contain toxic components,Scarlett, A., Rowland, S. J., Galloway, T. S., Lewis, A. C. & Booth, A. M.

20 January 2011 – PASKAL maritime counter-terrorism assault teams successfully thwarted an attempted hijacking by Somali pirates on the Malaysian chemical tanker, MT Bunga Laurel in the Gulf of Aden. The tanker, laden with lubricating oil and ethylene dichloride was headed for Singapore when attacked by a pirate mothership with 18 armed pirates about 300 nautical miles (555 km) east of Oman at 11.40pm. Under the cover of darkness, seven pirates armed with AK-47 assault rifles, light machine guns and pistols suddenly emerged from a skiff boat and began boarding the tanker, firing at random. The crew of MT Bunga Laurel activated the alarm and MISC Emergency Reporting Centre (ERC) received a security emergency indication at about 11.37pm.

Accessed November 15, 2008. Mooney was awarded a total of 17 patents, the latest being one for a catalytic converter for the small two-stroke engines, used in chainsaws, lawn mowers, and leaf blowers. His invention reduced hydrocarbon emissions by as much as 70%, improved fuel efficiency and added up to 40% more power while addressing the pollution of an engine that often produces large amounts of pollution due to the lubricating oil mixed with the fuel. As President of the Environmental and Energy Technology and Policy Institute, Mooney has worked with the Partnership for Clean Fuels and Vehicles of the United Nations Environment Programme to help end the use of leaded gasoline throughout the world.

Process speeds are generally not as fast as conventional dry abrasive blasting when using the equivalent size and type of media, in part because the presence of water between the media and the substrate being processed creates a lubricating cushion that can protect both the surface and the media, reducing breakdown rates. Reduced impregnation of blasting material into the surface, dust reduction and the elimination of static cling can result in a very clean surface. However wet blasting of mild steel will result in immediate or 'flash' corrosion of the blasted steel substrate due to the presence of water. The lack of surface recontamination also allows the use of single equipment for multiple blasting operations—e.g.

Here, digestion starts as partially chewed food is broken down by saliva from the salivary glands. As the salivary glands produce fluid and carbohydrate-digesting enzymes (mostly amylases), strong muscles in the pharynx pump fluid into the buccal cavity, lubricating the food like the salivarium does, and helping blood feeders, and xylem and phloem feeders. From there, the pharynx passes food to the esophagus, which could be just a simple tube passing it on to the crop and proventriculus, and then on ward to the midgut, as in most insects. Alternately, the foregut may expand into a very enlarged crop and proventriculus, or the crop could just be a diverticulum, or fluid filled structure, as in some Diptera species.

This proved useful in desert environments such as the Western Desert Campaign, where lubricating oil retained dust and sand. The open bolt design combined with cheap manufacture and rudimentary safety devices also meant the weapon was prone to accidental discharges, which proved hazardous. A simple safety could be engaged while the bolt was in the rearwards (cocked) position. However, if a loaded Sten with the bolt in the closed position was dropped, or the butt was knocked against the ground, the bolt could move far enough rearward to pick up a round (but not far enough to be engaged by the trigger mechanism) and the spring pressure could be enough to chamber and fire the round.

Towed by , Barite departed San Francisco on 25 September 1944 and entered Pearl Harbor on the morning of 2 October. Clearing that port four days later, again astern of Iroquois, the barge proceeded to Eniwetok. Thence, under tow by the auxiliary ocean tug ATA-124, with as "retriever" and YMS-276 as escort, Barite reached Ulithi, in the Caroline Islands, on 13 January 1945 and joined the armada of 225 ships present at that advanced base. Barite served at Ulithi as a floating lubricating oil facility into the spring of 1945, when the advent of the typhoon season made it imperative to shift Service Squadron (ServRon) 10's base to locales other than the Western Caroline Islands.

The main application of ZDDPs are as anti-wear additives in lubricants including greases, hydraulic oils, and motor oils. ZDDPs also act as corrosion inhibitors and antioxidants. They are almost ubiquitous in lubricants, and treatment rates are usually between 600 ppm for modern, energy-conserving low-viscosity oils to 2000 ppm of this additive in some racing oils. It has been reported that zinc and phosphorus emissions may damage catalytic converters and standard formulations of lubricating oils for gasoline engines now have reduced amounts of the additive due to the API limiting the concentration of this additive in new API SM and SN oils; however, this affects only 20- and 30-grade "ILSAC" oils.

Lubricating oil creates a separating film between surfaces of adjacent moving parts to minimize direct contact between them, decreasing frictional heat and reducing wear, thus protecting the engine. In use, motor oil transfers heat through conduction as it flows through the engine. In an engine with a recirculating oil pump, this heat is transferred by means of airflow over the exterior surface of the oil pan, airflow through an oil cooler, and through oil gases evacuated by the positive crankcase ventilation (PCV) system. While modern recirculating pumps are typically provided in passenger cars and other engines of similar or larger in size, total-loss oiling is a design option that remains popular in small and miniature engines.

The petroleum industry, both production and refining, began in 1848 with the first oil works in Scotland. The chemist James Young set up a tiny business refining the crude oil in 1848. Young found that by slow distillation he could obtain a number of useful liquids from it, one of which he named "paraffine oil" because at low temperatures it congealed into a substance resembling paraffin wax. In 1850 Young built the first truly commercial oil-works and oil refinery in the world at Bathgate, using oil extracted from locally mined torbanite, shale, and bituminous coal to manufacture naphtha and lubricating oils; paraffin for fuel use and solid paraffin were not sold till 1856.

Oil analysis professionals and analysts can get certified in compliance with ISO standards by passing exams administered by the International Council for Machinery Lubrication (ICML). For purposes of Oil Analysis Program (OAP) trend analysis, replacement, replenishment or drain and flush of lubricating fluids in excess of half an engine’s oil capacity (2.5 gallons or more) will be considered an Oil Change and the engine will be placed in code Charlie (C) for three flights to establish a new working trend. Oil-Wetted Maintenance (OWM) is any replacement of engine components within an oil-lubricated system (bearings, gearbox, pumps, etc.). OWM actions shall be documented on DD Form 2026 and submitted to OAP lab for update of Oil Analysis database.

The pre-heating time depends on the engine design, the type of heating used and the ambient temperature, but for most engines in a temperate climate generally ranges from 2–5 minutes to as much as half an hour if operating in extreme cold or the engine is especially large. The engine is then turned over, usually by hand, but sometimes by compressed air or an electric motor. Once the engine is running, the heat of compression and ignition maintains the hot bulb at the necessary temperature, and the blow-lamp or other heat source can be removed. Thereafter, the engine requires no external heat and requires only a supply of air, fuel oil and lubricating oil to run.

A box of Crosman CO2 Powerlets. A Powerlet cartridge, commonly referred to as a charger, is a small disposable metal gas cylinder holding of liquid and often a small quantity of lubricating oil, used as a pneumatic power source for certain air guns, airsoft guns, paintball guns, and for quick inflation of various devices such as a personal flotation device. Originally developed and the trademark owned by Crosman Corporation and introduced to the market in 1954, the Powerlet cartridge has become the dominant source of power for inexpensive, rapid fire air guns from many manufacturers. Typically made of aluminium material, a Powerlet cartridge typically provides 20 to 40 shots in an airgun, depending on the gun and environmental conditions.

In line with her original Canadian Arctic Shipping Pollution Prevention Regulations (CASPPR) Arctic Class 4 rating, Terry Fox is designed to break at least first-year level ice with a continuous speed of . During icebreaking operations, the ice friction is reduced by lubricating the hull-ice interface with a low-pressure air bubbling system developed by Wärtsilä. In open water, the system can also act as a bow thruster and used for maneuvering together with the ship's single centerline rudder and a transverse stern thruster. When operating in ice-free waters, the ship was designed transit at an economical speed of about with just two main engines, but her maximum speed is quoted as .

Front-wheel drive layout had been highly impacted by the success of small, inexpensive cars, especially the British Mini. As engineered by Alec Issigonis, the compact arrangement located the transmission and engine sharing a single oil sump — despite disparate lubricating requirements — and had the engine's radiator mounted to the side of the engine, away from the flow of fresh air and drawing heated rather than cool air over the engine. The layout often required the engine be removed to service the clutch. As engineered by Dante Giacosa, the Fiat 128 featured a transverse-mounted engine with unequal length drive shafts and an innovative clutch release mechanism — an arrangement which Fiat had strategically tested on a previous production model, the Primula, from its less market-critical subsidiary, Autobianchi.

Ready for production in 1964, the Primula featured a gear train offset from the differential and final drive with unequal length drive shafts. The layout enabled the engine and gearbox to be located side by side without sharing lubricating fluid while orienting the cooling fan toward fresh air flow. By using the Primula as a test-bed, Fiat was able to sufficiently resolve the layout's disadvantages, including uneven side-to-side power transmission, uneven tire wear and potential torque steer, the tendency for the power of the engine alone to steer the car under heavy acceleration. After the 128, Fiat further demonstrated the layout's flexibility, re-configurating the 128 drive- train as a mid-engined layout for the Fiat X1/9.

The ship was torpedoed by the German U-boat commanded by Rosenberg-Gruszczynski on 1 May 1915, despite America being a neutral party in the war at that time. The ship left Port Arthur on 10 April carrying a cargo of gasoline in the ship's tanks and barrels of lubricating oil to Rouen, FranceNewspaper report including personal account of the first officer During the latter half of the voyage the ships radio operator had heard messages from a British cruiser which judging from the transmission strength had been keeping station with Gulflight. At a point west of the Bishop Rock lighthouse, Scilly Isles, at 11 a.m. on 1 May, Gulflight was challenged by two British patrol vessels, HMS Iago and HMS Filey, which queried her destination.

Fuel oil, lubricating oil and grease, and ammonium sulfate were also produced. The European oil-shale industry expanded immediately before World War I due to limited access to conventional petroleum resources and to the mass production of automobiles and trucks, which accompanied an increase in gasoline consumption. Although the Estonian and Chinese oil-shale industries continued to grow after World War II, most other countries abandoned their projects due to high processing costs and the availability of cheaper petroleum.Dyni (2010), p. 97 Following the 1973 oil crisis, world production of oil shale reached a peak of 46 million tonnes in 1980 before falling to about 16 million tonnes in 2000, due to competition from cheap conventional petroleum in the 1980s.

The advantages of the gas spring include the ability to keep the gun cocked and ready to fire for extended periods of time without long-term spring fatigue, no twisting torque (caused by coil spring expanding) being exerted onto the gun, smoother recoil pattern and faster "lock time" (the time between pulling the trigger and the pellet being discharged), which all result in more consistent accuracy. Gas springs perform more reliably in cold climates than coil springs, because metallic coil springs need to be coated with lubricating grease which often over thickens in low temperatures causing the gun to "freeze up". Gas springs also have less lateral and longitudinal vibrations than coil springs, hence are usually less "hold-sensitive", making it easier to achieve consistent shot groupings.

The 348 did not break from tradition in this area, requiring careful adjustment and lubricating considerations, as well as full warm up, and was found to perform best with quick and aggressive driving. "It's only when you allow the engine full voice that the 348's drivetrain really works," mentioned Mike McCarthy of May 1994's Wheels Magazine. "Only then does this drivetrain achieve harmony," with the gear lever "moving fast and fluidly," leaving "no surprise to anyone who knows why Ferrari has the reputation it does," summarizing it to be, "very much like what you imagine a Ferrari might be." Paul Dean described, “Gears are given up smoothly only when the moment, the engine, the clutch and shift are in concert.

Lotion Play is a subset of the better known Wet-And-Messy fetish (WAM), which typically involves participants using food (such as pudding or whipped cream), mud, or paint as a lubricant to facilitate sexual activity. Lotion Play isolates lotion specifically as a lubricating medium - setting it apart in the Wet-and-Messy genre, as other common WAM mediums do not have such specific popularity as Lotion Play. , also known as gookkake, gluekkake, is a popular fetish, form of Japanese erotica and prostitution request involving the use of copious amounts of lubricant, which in the Japanese language is referred to by the Old-French word "lotion" (ローション in Japanese).Typically lotion play involves a participant rubbing lotion on another using their body,Talmadge, Eric.

The Rover class were single hulled tankers, designed to carry a mixture of fuel oil, aviation fuel, lubricating oil and fresh water supply for services around the globe; they could also carry limited dried stores of 340 tonnes such as munitions and refrigerated goods. They were built with a flight deck large enough to accommodate two helicopters, although no hangar was fitted. Although not big enough to support a large task group, these ships are ideal for supporting individual warships or small groups on deployment. The keel of Green Rover was laid at Swan Hunter Shipbuilders Ltd's Hebburn yard on the River Tyne, UK on 28 February 1968, she was launched on 19 December the same year, and completed on 15 August 1969.

He left BOAC in 1952 and spent the next year working on a biography, Jet: The Story of a Pioneer. He was awarded the Royal Society of Arts' Albert Medal that year. Returning to work in 1953, he accepted a position as a Mechanical Engineering Specialist with Shell, where he developed a new type of self-powered drill driven by a turbine running on the lubricating mud that is pumped into the borehole during drilling. Normally a well is drilled by attaching rigid sections of pipe together and powering the cutting head by spinning the pipe from the surface, but Whittle's design removed the need for a strong mechanical connection between the drill and the head frame, allowing for much lighter piping to be used.

It is concentrating on unique customized smart tools for laser cladding, laser cleaning, laser welding, laser ablation and laser soldering. Visotek's DLF Series high powered fiber coupled diode lasers and process expertise are incorporated into the new solid lubricating polymer film technology developed by TriboCoreLogic in Dundas, ON, Canada. After laser curing with the DLF Series System and special optic, this new coating maintains extreme adhesion to a metal substrate and provides a very low coefficient of friction, high load-carrying capacity and exceptional corrosion resistance. A significant advantage of the technology is its chamber-less application and portability of the system, making it highly suitable for surfaces of large, heavy and expensive equipment components, such as turbines, compressors and centrifuge shafts, journal bearings, hydraulic parts.

M/S Massalia was built by Dubigeon-Normandie S.A. in 1971 and delivered to Compagnie de Paquebots who put her on the route Marseille–Málaga–Casablanca and also cruises in the Mediterranean Sea. In 1984 she was owned by a number of companies and named Stena Baltica, Island Fiesta and finally Scandinavian Star, a name given to her by Scandinavian World Cruises which chartered the ship for cruises between St. Petersburg, Florida and Tampa, Florida to Cozumel, Mexico. The Scandinavian Star had had other fires prior to 1990. During the investigation of the fire, investigators learned that unreported fires had also occurred in 1985, caused by a deep-fryer, and again just days before the 15 March 1988 fire, caused by a broken lubricating pipe.

Sometimes fluid will be added to the wellbore to assist in bailing by bringing up the pressure, and also lubricating the downhole solid. Because the pressure inside the bailer is much less than the downhole wellbore pressure, any solids that are loose enough are 'sucked up' by the vacuum formed when the bottom plug is sheared and travels upwards through the barrel, followed by the solids. At the same time, due to the changed from negative pressure to positive pressure, the top plug pops out (and is caught by the top part of the tool), and excess flow is directed out through the 10 mm ports on the sides of the top of the tool. These ports allow the barrel to fill more readily.

Typical design of automobile engine connecting rod A connecting rod for an internal combustion engine consists of the 'big end', 'rod' and 'small end'. The small end attaches to the gudgeon pin (also called 'piston pin' or 'wrist pin'), which can swivel in the piston. Typically, the big end connects to the crankpin using a plain bearing to reduce friction; however some smaller engines may instead use a rolling-element bearing, in order to avoid the need for a pumped lubrication system. Typically there is a pinhole bored through the bearing on the big end of the connecting rod so that lubricating oil squirts out onto the thrust side of the cylinder wall to lubricate the travel of the pistons and piston rings.

The hydraulic and lubricating oil, called automatic transmission fluid (ATF), provides lubrication, corrosion prevention, and a hydraulic medium to convey mechanical power (for the operation of the transmission). Primarily made from refined petroleum, and processed to provide properties that promote smooth power transmission and increase service life, the ATF is one of the few parts of the automatic transmission that needs routine service as the vehicle ages. The multitude of parts, along with the complex design of the valve body, originally made hydraulic automatic transmissions much more complicated (and expensive) to build and repair than manual transmissions. In most cars (except US family, luxury, sport-utility vehicle, and minivan models) they have usually been extra-cost options for this reason.

In 1980 an upgraded model, the GDF-002 was produced, which featured an improved sight, and the ability to be directed by an off-gun digital control system. A few years later a third version of the system was being produced, the GDF-003, which was broadly similar to the GDF-002, but included some enhancements like self-lubricating weapons and integrated protective covers. In 1985 a further upgraded model was produced, the GDF-005, which was introduced, featuring the Gunking 3D computer- controlled sight with an integrated laser range-finder and digital control system. The GDF-005 also introduced an automated ammunition-handling system, which eliminated the need for the two reloaders, reducing the crew from 3 to 1.

The single-most visual change was replacing the oversized custom pivot with a more traditional (Sebenza-style) pivot brushing. This new pivot no longer requires the Umnumzaan Take-down Tool and instead a traditional hex wrench is all that is needed to disassemble and reassemble the knife. This pivot is larger than most blade pivot brushing systems and is identical to the one used on the newer Large Sebenza 25 (mid-2012 release and with a pivot that is significantly thicker than the pivot used on the previous Large Sebenza 21). This pivot also incorporates a newer generation washer system with larger washer perforations, which helps retain lubricating grease better than previous designs, while simultaneously keeping elements out of the pivot system to increase service intervals.

It was also, for its day, very fuel-efficient, enabling longer flights carrying less fuel weight for given distances. Another key feature of the Whirlwind radial engine was that it was rated to self-lubricate the engine's valves for 40 hours continuously. Lubricating, or "greasing," the moving external engine parts was a necessity most aeronautical engines of the day required, to be done manually by the pilot or ground crew prior to every flight and would have been otherwise required somehow to be done during the long flight. The engine was built at Wright Aeronautical in Paterson, New Jersey by a 24-year-old engine builder, Tom Rutledge, who was disappointed that he was assigned to the unknown aviator, Lindbergh.

Simple two-stroke engines are lubricated on a "total loss" method, mixing lubricating oil with their fuel; they are estimated to create exhaust in excess of 25% of their fuel and oil unburned in addition to the products of incomplete and complete combustion. The 1990 amendments to the Clean Air Act allowed the U.S. Environmental Protection Agency to begin regulating all recreational marine engines including PWC, as well as other off-road internal combustion engines. The agency began a dialogue with manufacturers in 1991, resulting in regulations that were enacted in 1996. These regulations, set to phase in between 1998 and 2006, are considered averaging standards, because they allow manufacturers to offset more-polluting engines in their product range by offering other engines that exceed the standard.

Upon delivery Lightburne proceeded to Port Arthur to load her cargo and departed for Philadelphia on 10 September 1919 reaching her destination ten days later. The ship made a few more trips under USSB control before The Texas Co. acquired all eight tankers, they had built at their shipyard in Bath, in December 1919 for approximately 14,700,000 (Lightburnes price tag was set at 1,837,500). Following the transfer the ship continued carrying petroleum products between Gulf ports such as Port Arthur, Galveston and Port Eads and ports on U.S. eastern seaboard, such as Norfolk, Providence and Philadelphia throughout her career. In addition, the tanker occasionally made international trips, for example she delivered a cargo of oil, gasoline and lubricating oil to Antwerp and Amsterdam in October 1925.

Notable in the trial was the operating economy of the Diesel compared with the steam and particularly the gasoline engines in common use. In the five hour run, in which the ease of starting, reversing the engine and other operation was of fuel oil costing $1.14 with another forty cents of lubricating oil brought the total cost of the run to $1.54. The comparison with the estimated cost of a similar powered gasoline vessel was $13.90 with further benefit of a reduction in insurance cost for not having gasoline aboard also noted. Idealia first appears in the Forty Seventh Annual List of Merchant Vessels of the United States, 1915, with official number 213497, signal letters LDNM, port of registry New York, and owned by ELCO.

Refinery operations, ExxonMobil, retrieved 20 December 2012 Major process units include three atmospheric and three vacuum distillation units (although one atmospheric and one vacuum distillation unit was shut down in 2012), a fluid catalytic cracking unit, a resid finer, a polymerization plant, two powerformers, six hydrofiners (a new one was brought online in 2013), two sulphur extraction units, a lubricating oil manufacturing complex, an isomerization unit and a bitumen plant (which was shut down in 2009). In addition to this, the refinery is also home to the largest refrigerated LPG storage facility in Northern Europe. About 5% of Fawley's production is distributed by rail or road, 25% by sea and 70% by pipelines. The refinery at Fawley also supplies feedstock to the adjacent chemical plant.

In both cases, the supply of oil is proportional to the speed of the locomotive. Big-end bearing (with connecting rod and coupling rod) of a Blackmoor Vale showing pierced cork stoppers to oil reservoirs Lubricating the frame components (axle bearings, horn blocks and bogie pivots) depends on capillary action: trimmings of worsted yarn are trailed from oil reservoirs into pipes leading to the respective component. The rate of oil supplied is controlled by the size of the bundle of yarn and not the speed of the locomotive, so it is necessary to remove the trimmings (which are mounted on wire) when stationary. However, at regular stops (such as a terminating station platform), oil finding its way onto the track can still be a problem.

Once the DN factor of a bearing has been obtained, it can be used to consult grease selection charts in order to determine the correct lubricant. Viscosity must be matched to the needs of the bearing in order to obtain maximum efficiency, and to avoid lubricant runout due to overheating, which is a consequence of metal-on-metal contact, as well as the failure of grease to extract heat from the bearing system. Viscosity is quantified according to the National Lubricating Grease Institute (NLGI) consistency number, which is regarded as the standard measure of grease thickness. Knowing the DN factor of a bearing is critical to preventing lubricant starvation, which is characterized by decreasing lubricant film thickness coupled with increased bearing speed.

The dropping point of a lubricating grease is an indication of the heat resistance of the grease and is the temperature at which it passes from a semi-solid to a liquid state under specific test conditions. It is dependent on the type of thickener used and the cohesiveness of the oil and thickener of a grease.Totten, G.E., Handbook of Lubrication and Tribology Volume 1: Application and Maintenance, CRC Press, 2006, The dropping point indicates the upper temperature limit at which a grease retains its structure though is not necessarily the maximum temperature at which a grease can be used. Dropping point is used in combination with other testable properties to determine the suitability of greases for specific applications and for use in quality control.

An example is lubricating oil for four-stroke or four-cycle internal combustion engines such as those used in portable electricity generators and "walk behind" lawn mowers. Another example is two-stroke oil for lubrication of two-stroke or two-cycle internal combustion engines found in snow blowers, chain saws, model airplanes, gasoline-powered gardening equipment like hedge trimmers, leaf blowers and soil cultivators. Often, these motors are not exposed to as wide of service temperature ranges as in vehicles, so these oils may be single viscosity oils. In small two-stroke engines, the oil may be pre-mixed with the gasoline or fuel, often in a rich gasoline:oil ratio of 25:1, 40:1 or 50:1, and burned in use along with the gasoline.

Test results indicate satisfactory performance from the oils tested.Canola-based Motor OilsPurdue University A review on the status of bio-based motor oils and base oils globally, as well as in the U.S, shows how bio-based lubricants show promise in augmenting the current petroleum-based supply of lubricating materials, as well as replacing it in many cases. The USDA National Center for Agricultural Utilization Research developed an Estolide lubricant technology made from vegetable and animal oils. Estolides have shown great promise in a wide range of applications, including engine lubricants. Working with the USDA, a California-based company Biosynthetic Technologies has developed a high-performance “drop-in” biosynthetic oil using Estolide technology for use in motor oils and industrial lubricants.

Rotax can provide a purpose-designed air intake, exhaust system and engine mount. The 914 oil system differs from most dry-sump designs in that lubricating oil is forced into the storage tank by crankcase pressure rather than by a separate scavenge pump. This requires a novel preflight inspection procedure: before checking the oil level with the dipstick, the engine is "burped" by removing the oil filler cap and turning the propeller until a gurgling sound is heard, which indicates that all oil has been forced into the tank and the oil level can now be checked accurately. The 914 is more fuel efficient and lighter than similarly sized traditional engines, but originally had a shorter time between overhaul (TBO), restricting its market potential.

Sulfur is not a lubricant in and of itself, but it can combine with the nickel content in many metal alloys to form a low melting point eutectic alloy that can increase lubricity. The process used to reduce the sulfur also reduces the fuel's lubricating properties. Lubricity is a measure of the fuel's ability to lubricate and protect the various parts of the engine's fuel injection system from wear. The processing required to reduce sulfur to 15 ppm also removes naturally occurring lubricity agents in diesel fuel. To manage this change ASTM International (formerly the American Society for Testing and Materials) adopted the lubricity specification defined in ASTM D975 for all diesel fuels and this standard went into effect January 1, 2005.

For use in the locomotive the engine was rated at 1600 hp at 750rpm; the engine was water-cooled. Water, lubricating oil and fuel pumps were driven from one end of the engine's crankshaft. Two Serck radiators were used for cooling, each with water and oil cooling elements.Britain's First Main-Line Diesel-Electric Locomotives, (English Electric). pp.2-3; Fig.5 pp.6-7 The main generator was a 1080 kW 650 V 1660 A continuous rated self-ventilated machine directly connected to the engine's crankshaft and supported by an extension of the diesel engine's bedplate. The generator used two separately excited field windings whilst generating, using a series winding for battery-powered (60 cell, 236 Ahr, D.P. Kathanode) motor starting.

After the closure of Deptford's Royal Dockyard in 1869 the Victualling Yard expanded southwards into the old Dockyard precincts; by the end of the century it covered a total area of some 35 acres. Brewing had ceased in the yard after the beer ration was discontinued in the 1830s; and live animals were not brought into the yard after the 1870s (though fresh meat continued to be salted on site). The old brewhouse instead became a clothing store, and in the 20th century a whole variety of stores were kept on site, including medical supplies, lubricating oil and acid as well as milk, jam and lime juice. The cooperage, however, remained in use as produce continued to be stored in barrels.

Yakutat tended the PBM Mariners of Patrol Bomber Squadron 27 (VPB-27) for the rest of World War II. She established seadrome operations at Kerama Retto on 28 March 1945 and spent the rest of the important Okinawa campaign in seaplane tending duties. The presence of Japanese aircraft in the vicinity on numerous occasions meant many hours spent at general quarters stations, lookouts' eyes and radar alert for any sign of approaching enemy planes. Yakutat provided quarters and subsistence for the crews of the Mariners and furnished the planes with gasoline, lubricating oil, and jet-assisted take-off (JATO) units. The Mariners conducted antisubmarine and air-sea rescue ("Dumbo") duties locally, as well as offensive patrols that ranged as far as the coast of Korea.

"Setting up" a violin is generally considered to be a separate activity, and may be done many times over the lengthy service life of the instrument. Setup includes fitting and trimming tuning pegs, surfacing the fingerboard, carving the soundpost and bridge, adjusting the string spacing and action height, and other tasks related to putting the finished instrument into playing condition and optimizing its "voice" (its sound, tone, and timbre) and responsiveness to playing. Violin maintenance goes on as long as the instrument is to be kept in playing condition, and includes tasks such as replacing strings, positioning the soundpost and bridge, lubricating pegs and fine tuners, resurfacing the fingerboard, attending to the instrument's finish, and restoring, repairing, or replacing parts of the violin or its accessories which have suffered wear or damage.

Another issue affecting the compatibility between HFO-1234yf and R-134a-based systems is the choice of lubricating oil. Shortly after confirmation from automakers that HFO-1234yf would be adopted as a replacement of R-134a automotive air-conditioning refrigerant, in 2010, Honeywell and DuPont announced that they would jointly build a manufacturing facility in Changshu, Jiangsu Province, China to produce HFO-1234yf."Automakers Go HFO", Chemical & Engineering News, July 26, 2010 In 2017, Honeywell opened a new plant in Geismar, Louisiana, USA to produce the new refrigerant as well. Although others claim to be able to make and sell HFO-1234yf, Honeywell and DuPont hold most or all of the patents issued for HFO-1234yf and are considered the leading players in this area as of 2018.

In 1887, founder Hiram Bond Everest and son Charles M. Everest were charged with conspiracy to destroy competitor Buffalo Lubricating Oil Co. It was alleged that, having sold a three-quarter interest in their company to Standard Oil, they were attempting to destroy their rival's refinery, preventing it from manufacturing petroleum products, and from acquiring Vacuum's skilled employees. One employee who had left Vacuum to work for Buffalo was Albert A. Miller, who was bribed to sabotage the new company's plant, causing an explosion. Hiram and Charles Everest were both found guilty, but there was insufficient evidence to prove the allegation that the Everests had acted under instructions from Standard Oil. In 1907, Vacuum Oil, Standard Oil, New York Central Railroad, and Pennsylvania Railroad were all indicted for violations in Inter-State Commerce laws.

If it is not operated frequently enough, the lubricant on the seals slowly evaporates, and then the seals begin to leak until the system is no longer functional and must be recharged. By comparison, a hermetic or semi-hermetic system can sit unused for years, and can usually be started up again at any time without requiring maintenance or experiencing any loss of system pressure. Even well lubricated seals will leak a small amount of gas over time, particularly if the refrigeration gasses are soluble in the lubricating oil, but if the seals are well manufactured and maintained this loss is very low. The disadvantage of hermetic compressors is that the motor drive cannot be repaired or maintained, and the entire compressor must be replaced if a motor fails.

In February 1942, partisans set ablaze a German fuel depot in Bender railway station, destroying hundreds of oil barrels and 17 full and 13 partially full gasoline tank cars. Days later, a carriage with lubricating oil belonging to Romanian Army suffered the same fate. Rail infrastructure was a primary target during the summer: two train collisions occurred in early August in Etulia and Ungheni, a railway bridge linking Etulia to Vulcănești was destroyed on 26 August and two cars carrying fodder and military equipment were set on fire on 28 August between Chircăiești and Hagimus. Other attacks resulted in the destruction of an oil factory in Otaci, the meat processing plant in Chișinău, the electrical substations in Bălți and Soroca, and damage to depots in Tiraspol and Bulboaca.

During World War II the refinery was identified as an asset to be "protected at all cost" as a major supplier of aircraft fuel for the Allied forces. By 1940, the refinery went through another expansion, a top secret project known as Project 1234 and by May 1942, the first Catalytic Cracking Unit came on stream where refining capacity in Trinidad and Tobago was recorded at 28.5 million barrels per year. At the end of World War II, the refinery was recognized as the largest in the British empire. In 1956, Trinidad Leaseholds Ltd was acquired by Texaco where by April 1960, the No 8 Topping Unit came on stream along with a lubricating oil plant, canning plant and a paraffins plant with production increasing and peaking to 360,000 barrels per day by 1970.

Whilst they steamed well and were capable of hauling the 50 wagon trains they were designed for, the locomotives were extremely slow on the uphill sections of the line, had high coal and lubricating oil consumption, and were prone to overheating bearings. The marine pattern big ends were particularly prone to failure. Their performance and reliability was so poor that the company agreed to pay drivers and firemen a bonus of sixpence per single trip with a 279, provided they managed to complete at least three-quarters of the distance between Glasgow and Carlisle without it suffering a failure. For the G&SWR;'s next batch of goods engines Drummond designed the 403 class, which was a superheated development of the 279 class with a leading pony truck.

Manual transmissions use a mechanical clutch to transmit torque, rather than a torque converter, thus avoiding the primary source of loss in an automatic transmission. Manual transmissions also avoid the power requirement of the hydraulic control system, by relying on the human muscle power of the vehicle operator to disengage the clutch and actuate the gear levers, and the mental power of the operator to make appropriate gear ratio selections. Thus the manual transmission requires very little engine power to function, with the main power consumption due to drag from the gear train being immersed in the lubricating oil of the gearbox. The on-road acceleration of an automatic transmission can occasionally exceed that of an otherwise identical vehicle equipped with a manual transmission in turbocharged diesel applications.

Siemens blamed the problem on the Voltol-based oil that was used to replace scarce castor oil for lubricating the engine but the type was withdrawn from service and replaced by Fokker D.VIIs. When they were removed, Rudolf Berthold, commander of JG.II, noted that he felt "the Siemens fighter be made available again for front-line use as quickly as possible for, after elimination of the present faults, it is likely to be become one of our most useful fighter aircraft". A version of the Sh.III passed a 40-hour endurance test in June and the aircraft were cleared to return to service in July. In the meantime they had been upgraded with the addition of a new rudder, balanced ailerons and had the cowling cut-away for improved cooling.

Watering a steam locomotive South African Class 25 condensing locomotive Steam locomotives consume vast quantities of water because they operate on an open cycle, expelling their steam immediately after a single use rather than recycling it in a closed loop as stationary and marine steam engines do. Water was a constant logistical problem, and condensing engines were devised for use in desert areas. These engines had huge radiators in their tenders and instead of exhausting steam out of the funnel it was captured, passed back to the tender and condensed. The cylinder lubricating oil was removed from the exhausted steam to avoid a phenomenon known as priming, a condition caused by foaming in the boiler which would allow water to be carried into the cylinders causing damage because of its incompressibility.

In 1847 Young had his attention called to a natural petroleum seepage in the Riddings colliery at Alfreton, Derbyshire from which he distilled a light thin oil suitable for use as lamp oil, at the same time obtaining a thicker oil suitable for lubricating machinery. In 1848 Young left Tennants', and in partnership with his friend and assistant Edward Meldrum, set up a small business refining the crude oil. The new oils were successful, but the supply of oil from the coal mine soon began to fail (eventually being exhausted in 1851). Young, noticing that the oil was dripping from the sandstone roof of the coal mine, theorised that it somehow originated from the action of heat on the coal seam and from this thought that it might be produced artificially.

Vitaly is a muscular Siberian tiger with a Russian accent who leads a traveling circus in Madagascar 3: Europe's Most Wanted. The tough Vitaly once jumped through flaming rings of fire to excite crowds, constantly pushing himself to the limit by jumping through smaller and smaller rings that seemed impossible for his size while lubricating himself with olive oil. But after losing his confidence and more than a few of his hairs on one fateful attempt which involved a flaming ring that would only fit on the smallest finger (due to the olive oil being flammable), he also lost his passion and his act partially. When Alex and his friends plead with the circus to let them escape on their train, Vitaly is the most resistant, only to be overruled by Gia.

The layout enabled the engine and gearbox to be located side by side without sharing lubricating fluid while orienting the cooling fan toward fresh air flow. By using the Primula as a test-bed, Fiat was able to sufficiently resolve the layout's disadvantages, including uneven side-to-side power transmission, uneven tire wear and potential torque steer, the tendency for the power of the engine alone to steer the car under heavy acceleration. Fiat quickly demonstrated the layout's flexibility, re-configuring the 128 drive- train as a mid-engined layout for the Fiat X1/9, and the compact, efficient layout -- a transversely-mounted engine with transmission mounted beside the engine driving the front wheels through an offset final-drive and unequal- length driveshafts -- subsequently became common with competitors and arguably an industry standard.

Around this time, Goble also developed a networking protocol for Unix, referred to as pnet, which was used at Purdue at the time before being displaced by TCP/IP. Pnet allowed remote logins, and remote execution of commands, among other capabilities. In the late 1980s, Goble started experimenting with refrigerants, due to increased danger and lower thermodynamic efficiency of the recently introduced R-134a compared to the older R-12 which was being phased out due to concerns about damage to the ozone layer, and the incompatibility of R-134a with the lubricating oil and other materials used in systems built for R-12. In 1987, he converted the beverage refrigerators in the Eta Kappa Nu lounge in the basement of the Purdue Electrical Engineering building to using a refrigerant of his own devising.

The Soviet Union had prohibited the aircraft from landing on its soil, necessitating stops in the Territory of Alaska and Bering Sea area as the aircraft bypassed Soviet territory. Eider transported the advance personnel, supplies, gasoline, and lubricating oil needed to support the early stages of the trip to several locations in Alaska and the Bering Sea and provided the pilots with accommodations, meals, meteorological information, and moorings for the planes. Ultimately, two of the original airplanes completed the trip successfully by arriving at Seattle on 28 September 1924, 175 days after departing Naval Air Station Sand Point. By the mid-1920s, Eider′s patrol duties had expanded to include the protection of salmon in Southwest Alaska. In 1925, a 12-horsepower (10.1-megawatt) Cummins auxiliary diesel engine was installed aboard her.

The AP automatic transmission is a 4-speed automatic transmission unit developed by Automotive Products and the British Motor Corporation specifically for use in the Mini. It was unique in that not only was it one of the first transverse mounted automatic transmission units tailored for front wheel drive, it was one of the smallest in order to be used in the transmission-in-sump installation beneath the A-series engine used in the Mini, and later the 1100/1300 ranges. Another novel feature was that the transmission was designed to use the engine's lubricating oil, rather than conventional automatic transmission fluid (ATF). The units were manufactured in a BMC plant in Kings Norton, Birmingham which supplied complete powertrain packages (the unit required a unique engine variant) to the Longbridge and Cowley assembly plants.

The membrane layers can be printed by very-high volume, low-cost "reel-to-reel" printing machines, with each keyboard membrane cut and punched out afterwards. Plastic materials played a very important part in the development and progress of electronic keyboards. Until "monoblocks" came along, GE's "self-lubricating" Delrin was the only plastic material for keyboard switch plungers that could withstand the beating over tens of millions of cycles of lifetime use. Greasing or oiling switch plungers was undesirable because it would attract dirt over time which would eventually affect the feel and even bind the key switches (although keyboard manufacturers would sometimes sneak this into their keyboards, especially if they could not control the tolerances of the key plungers and housings well enough to have a smooth key depression feel or prevent binding).

In addition to this nanotechnology is being researched for introduction into production lines in order to improve the quality standards and customer satisfaction by offering anti-bacterial seats, anti-scratch paint, hydrophobic glass panes, maintenance-free air filters, anti-stain dashboards, nano- catalytic converters and nano-diamond containing lubricating oils. In 2011, the Nanotechnology Initiative Council announced plans to export to Lebanon a series of ‘home-made’ nano-based engine oils manufactured by the Pishgaman–Nano-Aria Company (PNACO); these nano-based oils reduce engine erosion, fuel consumption and engine temperature. In 2009, researchers at Isfahan University of Technology developed a strong but light nanosteel as resistant to corrosion as stainless steel for use in road vehicles but also potentially in aircraft, solar panels and other products. As of 2016, Iran had no known R&D; project in the field of autonomous cars.

This is the reason snorers are advised to lose weight (to stop fat from pressing on the throat), stop smoking (smoking weakens and clogs the throat), avoid alcohol and sedative medications before bedtime (they relax the throat and tongue muscles, which in turn narrow the airways) and sleep on their side (to prevent the tongue from blocking the throat). A number of other treatment options are also used to stop snoring. These range from over-the- counter aids such as nasal sprays, nasal strips or nose clips, lubricating sprays, oral appliances and "anti-snore" clothing and pillows, to unusual activities such as playing the didgeridoo. However, one needs to be wary of over-the-counter snore treatments that have no scientific evidence to support their claims, such as stop-snore rings or wrist worn electrical stimulation bands.

Toti was lubricating the engine of the locomotive and, when the locomotives moved, he slipped causing left leg being trapped and crushed by the gears. The development of the town began as early as 1912 with the conversion of a long disused sugar factory (the Valsacco factory) to an explosive factory. Initially, the town developed away from where the center is today; the first few buildings (including the Church of St. Joachim) were built within the territory of the nearby town of Valmontone, near the train station that was then called "Segni-Paliano", and was renamed "Segni-Station Colleferro" after the birth of the town. The engineer Leopoldo Parodi Delfino (former senator and son of the founder of the National Bank, then Bank of Italy) and Senator Giovanni Bombrini founded the 'Bombrini Parodi Delfino explosives factory.

The bulk of these ships came under the Ministry of War Transport and carried oil to the storage tanks at Port-en-Bessin, others under control of the Royal Navy carried diesel, petrol and water, all destined for the advancing armies. This particular class of ship was not renowned for its stability and when loaded had to carry much ballast, as well as cargo in their tanks they also carried up to ten tons of lubricating oil on deck and were well armed considering their vulnerability. On D-Day plus three Chant 60 turned turtle when manoeuvring under full helm, fortunately her entire crew were rescued later, carrying a full load of petrol she was towed away from the beach and sunk by a British destroyer. Chant 69, this time carrying water performed a similar evolution a short while later.

The purpose of the Dufour’s gland is to secrete chemicals, but the nature of the secretions and their function differs in various hymenopteran groups. The secretion is often used in communication to mark members of the colony, to mark hosts (parasitic wasps), during slave raids (ants), for territory marking (ants), to signal fertility, to attract a member of the opposite sex, to give an alarm warning (ants) or to mark a trail (ants). This use of scent marking pheromones secreted by Dufour's gland is observed in the carpenter bee Xylocopa pubescens to mark flowers and nests. Other functions include lubricating the valves of the ovipositor during egg- laying, serving as a component of material used to build the nest, serving as a food for the developing larvae and being mixed with pollen and nectar to provision the brood cell before egg-laying.

The company was making a major effort to dominate the lubricating oil business, and Squire became the company's agent in negotiating the purchase of two key distribution companies based in New York City: Libby, Bartlett & Kimball and Thompson & Bedford. The following year, Squire was made vice president of the Chesebrough Manufacturing Company, which manufactured and sold petroleum jelly under the brand name Vaseline and which had been acquired by Standard Oil in 1880. Squire was made secretary of Standard Oil in early 1885. In March, just after he had taken up his duties, oil refiner George Rice accused Squire, Standard Oil vice president Frank Rockefeller, and Oklahoma businessman Charles N. Haskell (later the first Governor of Oklahoma) of attempting to bribe a clerk in the firm of Scofield, Shurmer & Teagle (Squire's old petroleum company) in order to learn that company's financial secrets.

Mad magazine announced the "Trac 76", arranged as a chain of cartridges with a handle on each end. In the early 1990s, the (Australian) Late Show skitted a "Gillette 3000" with 16 blades and 75 lubricating strips as arrived at by working in conjunction with the help of NASA scientists - "The first blade distracts the hair...". The 16 January 1999 episode of Mad TV ran a parody commercial advertising the "Spishak Mach 20" with blades that variously "cut(s) away that pesky second layer of skin" and "gently smooth(s) out the jawbone" culminating in a blade that "destroys the part of the brain responsible for hair growth." In 2004, a satirical article in The Onion entitled "Fuck Everything, We're Doing Five Blades" predicted the release of five-blade cartridges, two years before their commercial introduction.

S84/98 III bayonet and scabbard When issued the Karabiner 98k came accompanied with assorted accessory items including a sling, a protective muzzle cover, and for field maintenance a Reinigungsgerät 34 ("Cleaning Kit 34") or RG34 kit. Introduced in 1934, the Reinigungsgerät 34 consisted of a flat wide by long sheet metal container with two hinged lids carried on the person, which held an oiler, a take down tool for removing the floorplate and cleaning the receiver of the rifle, an aluminum barrel pull- through chain, a cleaning and an oiling brush, and short lengths of tow used as cleaning patches. From 1905 until 1945 the German military used Ballistol intended for cleaning, lubricating, and protecting metallic, wooden and leather firearms parts. The Karabiner 98k rifle was designed to be used with an S84/98 III bayonet.

The weight of the Monosoupape was slightly less than the earlier two-valve engines, and it used less lubricating oil. The 100 hp Monosoupape was built with 9 cylinders, and developed its rated power at 1,200 rpm. The later 160 hp nine-cylinder Gnome 9N rotary engine used the Monosoupape valve design while adding the safety factor of a dual ignition system, and was the last known rotary engine design to use such a cylinder head valving format. A German Oberursel U.III engine on museum display Rotary engines produced by the Clerget and Le Rhône companies used conventional pushrod-operated valves in the cylinder head, but used the same principle of drawing the fuel mixture through the crankshaft, with the Le Rhônes having prominent copper intake tubes running from the crankcase to the top of each cylinder to admit the intake charge.

The delivery of the aerosol is directly through the flutes of the tool (it arrives directly through or around the insert itself—an ideal type of cutting fluid delivery that traditionally has been unavailable outside of a few contexts such as gun drilling or expensive, state-of-the-art liquid delivery in production milling). MQL's aerosol is delivered in such a precisely targeted way (with respect to both location and timing) that the net effect seems almost like dry machining from the operators' perspective. The chips generally seem like dry-machined chips, requiring no draining, and the air is so clean that machining cells can be stationed closer to inspection and assembly than before. MQL doesn't provide much cooling in the sense of heat transfer, but its well-targeted lubricating action prevents some of the heat from being generated in the first place, which helps to explain its success.

In 1992, Caltrans released the first feasibility study detailing the possibility of electrifying the railroad between San Francisco and San Jose. The 1992 Feasibility Study proposed replacing the existing diesel-electric locomotives with either a fleet of EMD AEM-7 electric locomotives to move the existing gallery passenger cars or Metro North Budd M-2/M-4 EMUs. The primary benefits of an electrified railway would be improvements in air quality, noise, and acceleration, but would also save on other ancillary costs, such as lubricating oil, cooling water, maintenance, and refueling. Because of the relatively close spacing between stops, the improved acceleration using electric locomotives compared to the existing diesel-electric locomotives would cut transit time between San Francisco and San Jose by up to twelve minutes, and using EMUs would cut the time over the same distance by up to 23 minutes, assuming the use of ten-car trainsets.

A novel, pneumatic device was employed which pumped the liquefied mud through a pipe over East Ferry Rd (close to the George pub), dumping it on the other side. This system was designed by dock engineer Frederic Eliot Duckham (father of Alexander Duckham who later founded his eponymous lubricating oil company in Millwall). The mud stank terribly, and Poplar Borough Council continually complained to the dock company that it was causing disease (including diphtheria) among locals, attempting unsuccessfully to have the mud dumping stopped. (Later Mudchute allotment holders who built wells to provide water to their plants complained at its condition, but it was some decades before the council pumped clean water to the Mudchute allotments.) By 1890, the Millwall Dock Company had not yet dumped mud on the northern edge of its land east of East Ferry Rd, which meant the ground was flat and solid.

TMJ arthrocentesis refers to lavage (flushing out) of the upper joint space (where most of the translation movement takes place) with saline via the introduction of cannulae. It is theorized that the hydraulic pressure generated within the joint combined with external manipulation is capable of releasing adhesions or the anchored disc phenomenon and leads to an improvement in the movement ("lysis and lavage"). It is also suggested that undesirable contents within the synovial fluid of the joint can be washed out, such as microscopic debris (from breakdown of the articular surfaces) and pain mediators (enzymes and prostaglandins), and there is also stimulation of the synovial membrane to restore its normal lubricating function. It was initially used to treat acute closed lock, however it has since come to be used chronic closed lock, chronic anterior displaced disc with reduction, and degenerative joint disease (e.g. arthritis).

The plant uses the Connecticut River as its source of cooling water. Unit 3, as a steam unit, has to reject waste heat from its condenser to a water source. A once-through cooling system utilizing water from the river removes waste heat from Unit 3's condenser. The circulating water pumps are located in the plant's pump house across the highway from the facility directly on the Connecticut River. Unit 3 can require up to 6 million gallons per day of water when operating. Units 1, 2, and 10 reject all of their waste heat from combustion to the atmosphere via the exhaust stacks. However, Units 1 and 2 do require a small amount of cooling water to remove heat from the lubricating oil system for the turbines. A small service water system operating at 730 gpm continuously provides cooling water for that purpose.

During her deployment to the South China Sea, Fort Worth encountered several warships of the People's Liberation Army Navy, putting the new rules of the Code for Unplanned Encounters at Sea into practice in a "professional" manner. On 12 January 2016, according to a memo from the service, it was reported that Fort Worth was sidelined in port at Singapore indefinitely because of damage to gears that propel the vessel, which resulted from a failure to use enough lubricating oil. As a result, on 28 March 2016, CDR Michael Atwell, the commander of LCS crew 101 (the LCS is manned by a rotating crew), was relieved of duty and was temporarily replaced by CDR Lex Walker, deputy commodore of Destroyer Squadron 7. The Navy cited the reason for CDR Atwell's removal was "due to a due to loss of confidence in Atwell's ability to command," stemming from initial findings into the incident that sidelined Fort Worth.

The production of these oils and solid paraffin wax from coal formed the subject of his patent dated 17 October 1850. In 1850 Young & Meldrum and Edward William Binney entered into partnership under the title of E.W. Binney & Co. at Bathgate in West Lothian and E. Meldrum & Co. at Glasgow; their works at Bathgate were completed in 1851 and became the first truly commercial oil-works in the world, using oil extracted from locally mined torbanite, lamosite, and bituminous coal to manufacture naphtha and lubricating oils; paraffin for fuel use and solid paraffin were not sold till 1856. In 1852 Young left Manchester to live in Scotland and that same year took out a US patent for the production of paraffin oil by distillation of coal. Both the US and UK patents were subsequently upheld in both countries in a series of lawsuits and other producers were obliged to pay him royalties.

Most rotaries had normal inlet valves, so that the fuel (and lubricating oil) was taken into the cylinders already mixed with air - as in a normal four-stroke engine. Although a conventional carburetor, with the ability to keep the fuel/air ratio constant over a range of throttle openings, was precluded by the spinning crankcase; it was possible to adjust the air supply through a separate flap valve or "bloctube". The pilot needed to set the throttle to the desired setting (usually full open) and then adjust the fuel/air mixture to suit using a separate "fine adjustment" lever that controlled the air supply valve (in the manner of a manual choke control). Due to the rotary engine's large rotational inertia, it was possible to adjust the appropriate fuel/air mixture by trial and error without stalling it, although this varied between different types of engine, and in any case it required a good deal of practice to acquire the necessary knack.

Pauly started working as a carriage builder and mechanic in his father's workshop; he was constantly looking for technical improvements (such as a self-lubricating axle) and also ways to increase the comfort of passengers. He later moved away to settle in nearby Bern in order to sell his inventions to the rich patricians there; a written testimony advertising his own carriages and promoting his technical successes may be seen in the city's trade handbook of 1796.Alex Capus, Himmelststurmer - Zwolf Portraits (btb, Munich, Germany, July 2010)Hans Rudolf Degen, Schweitzer Flugtechniker und Ballonpioniere - vol. 63 of the series 'Schweizer Pioniere der Wirtschaft und Technik (Verein fur wirtschaftshistorische Studien, Meilen, 1996) However, all this ended when, in March 1798, more than 30,000 French soldiers marched on the Zähringerstadt in the medieval area of the city to secure free access to the Alpine passes for Napoleon Bonaparte, and also to rob the legendary Bernese treasury to finance the campaign in Egypt.

When Fiat began marketing the Fiat 128 in 1969 -- with its engine and gearbox situated in an in-line, transverse front-drive layout, combined unequal drive shafts, MacPherson strut suspension and an electrically controlled radiator fan -- it became the layout adopted by virtually every other manufacturer in the world for front-wheel drive. The approach of unequal drive shafts was crafted by Dante Giacosa. Transverse engine and gearbox front-wheel drive had been introduced to small inexpensive cars with the German DKW F1 in 1931, and made more widely popular with the British Mini. As engineered by Alec Issigonis in the Mini cars, the compact arrangement located the transmission and engine sharing a single oil sump -- despite disparate lubricating requirements -- and had the engine's radiator mounted to the side of the engine, but with fan blades shaped to expel heated air into the left wheel arch, and thus drawing cool rather than heated air over the engine.

More than 20 federal lawsuits naming KBR and seeking class-action status were filed in late 2008 and 2009 over the practice of operating "burn pits" at U.S. bases in both Iraq and Afghanistan and thus exposing soldiers to smoke containing dioxin, asbestos, and other harmful substances. The pits are said to include "every type of waste imaginable", with items such as "tires, lithium batteries, Styrofoam, paper, wood, rubber, petroleum-oil-lubricating products, metals, hydraulic fluids, munitions boxes, medical waste, biohazard materials (including human corpses), medical supplies (including those used during smallpox inoculations), paints, solvents, asbestos insulation, items containing pesticides, polyvinyl chloride pipes, animal carcasses, dangerous chemicals, and hundreds of thousands of plastic water bottles". A company statement responding to the allegations said that "at the sites where KBR provides burn pit services, the company does so ... in accordance with the relevant provisions" of its contracts as well as "operational guidelines approved by the Army".

An assortment of cleaning rods used for firearm maintenance: A short cleaning rod with a brass brush attached, a foldable cleaning rod with a nylon brush attached, a cleaning kit for a shotgun (note the thicker rod), and some different brushes. Firearm maintenance (or gun care for short) is a series of periodic preventive maintenance procedures aiming to ensure the proper function of a firearm, often with the use of a variety of specialized tools and chemical solutions. Typically such maintenance is performed by the owner of the firearm using either simple methods such as cleaning the firearm with oil or other cleaning solutions, or more sophisticated practices such as lubricating moving parts with oil/grease and recoating exposed surfaces with protective finishes such as varnishing or bluing. When a firearm presents with physical damage related to the ordinary use of the firearm, or when a firearm malfunctions in a life-threatening manner, a professional gunsmith should perform advanced maintenance to determine if the firearm is repairable and/or safe to shoot anymore.

According to a narrative report contained in project files, there was no evidence of the lease ever having been executed, so it was believed that Douglas occupied and used the premises without any written agreement. On 12 November 1942, the Secretary of War and Standard Oil Co. (San Francisco) entered into an agreement (unnumbered lease to run with lease W-868-ENG-4504), whereby Standard Oil agreed to install, operate, and maintain lubricating oil storage and distribution facilities at the site. In addition, on 20 December 1943, the CAA was granted a permit (to run with Lease No. W-868-ENG-4505) to use and occupy two parcels of land totaling 11.2 acres at the Modification Center for a radio range and communication building site, together with a right of way between the two parcels for establishing and maintaining subsurface cable lines. The original permit period ended 30 June 1944, however, the lease contained a provision for annual renewal, at the option of the government, through 30 June 1967.
