The sprockets in a cassette are usually held together by three small bolts or rivets for ease of installation. These keep the sprockets and spacers in the correct order and position when they are removed from the freehub body. When the sprockets need to be replaced due to wear or the user wishes to change gear ratios available, only the sprockets are replaced, not the ratchet mechanism. Cassettes also allow the use of sprockets with fewer teeth, as in micro drive systems.
|
|
Early automobiles were also largely driven by sprocket and chain mechanism, a practice largely copied from bicycles. Sprockets are of various designs, a maximum of efficiency being claimed for each by its originator. Sprockets typically do not have a flange. Some sprockets used with timing belts have flanges to keep the timing belt centered.
|
|
The system used two chain-lifters to lift the chain from the sprockets. The cyclist would then back-pedal to disengage the chain and then shift the sprocket cluster laterally to the desired position. It would then engage when the cyclist started pedalling again. To allow for the smaller sprockets to slide into the hub, the larger gears were away from the wheel (unlike modern sprockets).

The individual sprockets on a Hyperglide cassette or freewheel are designed specifically to work with their neighbours. For example, the 18-tooth sprocket on a wide-range cassette (such as one for a mountain bike) will have a different ramp pattern than the 18-tooth sprocket on a narrow-range cassette, because the number of teeth on the neighbouring sprocket requires a different ramp pattern for an optimal shift. As a result, cassettes are sold as a cohesive unit—rather than as individual sprockets—with all the sprockets on a given cassette designed to work with each other. However, some mixing and matching is possible for a custom gear range, as long as all the sprockets' ramps are compatible.

These perfs are commonly referred to as CinemaScope (CS) or "Fox hole" perfs. Their dimensions are in width by in height. Due to the size difference, CS perfed film cannot be run through a projector with standard KS sprocket teeth, but KS prints can be run on sprockets with CS teeth. Shrunken film with KS prints that would normally be damaged in a projector with KS sprockets may sometimes be run far more gently through a projector with CS sprockets because of the smaller size of the teeth.

To achieve such consistent relative differences the absolute gear ratios should be in logarithmic progression; most off-the-shelf cogsets do this with small absolute differences between the smaller sprockets and increasingly larger absolute differences as the sprockets get larger. Because sprockets must have a (relatively small) whole number of teeth it is impossible to achieve a perfect progression; for example the seven derailleur sprockets 14-16-18-21-24-28-32 have an average step size of around 15% but with actual steps varying between 12.5% and 16.7%. The epicyclic gears used within hub gears have more scope for varying the number of teeth than do derailleur sprockets, so it may be possible to get much closer to the ideal of consistent relative differences, e.g. the Rohloff Speedhub offers 14 speeds with an average relative difference of 13.6% and individual variations of around 0.1%. Racing cyclists often have gears with a small relative difference of around 7% to 10%; this allows fine adjustment of gear ratios to suit the conditions and maintain a consistent pedalling speed.

This problem was partially solved by the development of bushed chains, with the pins holding the outer plates passing through bushings or sleeves connecting the inner plates. This distributed the wear over a greater area; however the teeth of the sprockets still wore more rapidly than is desirable, from the sliding friction against the bushings. The addition of rollers surrounding the bushing sleeves of the chain and provided rolling contact with the teeth of the sprockets resulting in excellent resistance to wear of both sprockets and chain as well. There is even very low friction, as long as the chain is sufficiently lubricated.

Made at the Woolwich Arsenal, intended to tow the QF 18-pounder gun. The chassis and running gear came from the Vickers Light Tank Mk II, which first appeared in 1929. There were four large spoked road wheels in pairs, using Horstmann suspension with horizontal coil springs, and three return rollers. The front sprockets were solid, the rear sprockets spoked.

Lead weights on some links of the upper or return sections of the chains counterbalanced most of the car's weight. The car was pushed up from below, not pulled up from above: to prevent the chain buckling, it was enclosed in a conduit. At the bottom of the run, the chains passed around diameter sprockets. Smaller sprockets at the top guided the chains.

Soon after the introduction of the SHO V8 engine, widespread problems with the cam sprockets began to surface. Yamaha had used a relatively unusual method, called "swaging", of affixing the cam sprockets to the camshafts. The cam sprockets were fastened to the hollow camshafts by forcing a metal ball which was slightly larger than the interior diameter of the camshaft through the center of the camshaft, thus expanding the metal slightly and creating a mechanical bond between the cam sprocket and the camshaft. This method proved to be inadequate, and the cam sprocket could break loose from the camshaft and spin independently from the camshaft (or "walk").

|
In the case of bicycle chains, it is possible to modify the overall gear ratio of the chain drive by varying the diameter (and therefore, the tooth count) of the sprockets on each side of the chain. This is the basis of derailleur gears. A multi-speed bicycle, by providing two or three different-sized driving sprockets and up to 12 (as of 2018) different-sized driven sprockets, allows up to 36 different gear ratios. The resulting lower gear ratios make the bike easier to pedal up hills while the higher gear ratios make the bike more powerful to pedal on flats and downhills.

Throat Sprockets is an erotic horror novel by Tim Lucas, published in 1994. It concerns an unnamed protagonist's obsessive quest to learn all he can about a mysterious film called Throat Sprockets. As fixation on the film consumes his personal life, he develops a sexual fetish for women's throats, an affinity which begins spreading to global and apocalyptic proportions, as the film's cult status and legend grows. Since its publication, Throat Sprockets has been singled out as one of the outstanding works of contemporary horror fiction by two important reference books, Dark Thoughts by Stanley Wiater and Horror: Another 100 Best Books edited by Stephen Jones and Kim Newman.

The 501st Heavy Panzer Battalion (sPzAbt 501) reported in May 1943: The engine drove the front sprockets through a drivetrain connecting to a transmission in the front portion of the lower hull; the front sprockets had to be mounted relatively low as a result. The Krupp-designed 11-tonne turret had a hydraulic motor whose pump was powered by mechanical drive from the engine. A full rotation took about a minute.

300px The Stringbike is a bicycle that uses a rope and pulley drive system instead of a traditional bicycle chain and sprockets. It uses two Dyneema ropes attached to pulleys attached to swinging lever and cam mechanisms, one on each side of the bike. These mechanisms replace the round sprockets found on chain-driven bikes. Unlike some traditional 10-speed gears using a derailleur, there is no slippage when changing gear ratios.

158 Porsche had experience of this form of petrol-electric transmission extending back to 1901, when he designed a car that used it. Suspension for the "slack track" equipped Ferdinand consisted of six twin bogies (three per side) with longitudinal torsion bars, without any overlapping wheels or return rollers. There are sprockets at both ends of the vehicle. The drive sprockets are at the rear, while the front pair contain a drum brake system.

Lucien Charles Hippolyte Juy was a French industrialist who made derailleur gears. He is credited with making the first derailleur with a collapsible parallelogram. A hinged frame swung in and out from the frame and fed the chain to one of a number of sprockets attached to the hub. Juy's derailleurs, sold as Simplex derailleurs, were novel in having a jockey wheel to correct the tension of the chain as it moved across differently sized sprockets.

The cage is positioned under the desired sprocket by an arm that can swing back and forth under the sprockets. The arm is usually implemented with a parallelogram mechanism to keep the cage properly aligned with the chain as it swings back and forth. The other end of the arm mounts to a pivot point attached to the bicycle frame. The arm pivots about this point to maintain the cage at a nearly constant distance from the different sized sprockets.

Shimano 600 front derailleur (1980) Derailleur gears are a variable-ratio transmission system commonly used on bicycles, consisting of a chain, multiple sprockets of different sizes, and a mechanism to move the chain from one sprocket to another. Although referred to as gears in the bike world, these bicycle gears are technically sprockets since they drive or are driven by a chain, and are not driven by one another. Modern front and rear derailleurs typically consist of a moveable chain-guide that is operated remotely by a Bowden cable attached to a shifter mounted on the down tube, handlebar stem, or handlebar. When a rider operates the lever while pedalling, the change in cable tension moves the chain-guide from side to side, "derailing" the chain onto different sprockets.
|
|
The derailleur is used in the bicycle's gear system. The change in cable tension to switch gears moves a chain from side to side, "derailing" the chain onto different sprockets and, therefore, different gears.
|
|
For example, many participants place the handlebars in the upper position for better control, change the front and/or rear sprockets to improve acceleration, change the exhaust system, and eliminate fairings to reduce weight.

A shaft final drive is housed within a rear swingarm of a BMW R1200GS Power transfer from the gearbox to the rear wheel is accomplished by different methods. Chain drive uses sprockets and a roller chain, which requires both lubrication and adjustment for elongation (stretch) that occurs through wear. The lubricant is subject to being thrown off the fast-moving chain and results in grime and dirt build up. Chains do deteriorate, and excessive wear on the front and rear sprockets can be dangerous.

A Shimano Dura-Ace freehub A freehub is a type of bicycle hub that incorporates a ratcheting mechanism. A set of sprockets (called a "cassette") are mounted onto a splined shaft of the freehub to engage the chain. The ratcheting mechanism is a part of the hub, in contrast to a freewheel, an older technology, which contains both the sprockets and a ratcheting mechanism in a single unit separate from the hub. In many high-end and midrange bicycles, freehubs have replaced freewheel systems.

George is now an employee at Spacely's Space Sprockets, a manufacturer of "sprockets" and other high tech equipment. His job title is "digital index operator." His boss is Cosmo G. Spacely, noted for being short in both height and temper; Spacely usually treats his employees (particularly George) in a rather tyrannical fashion. George's job primarily requires him to repeatedly push a single button (or on occasion a series of buttons) on a computer (named RUDI {Short for: Referential Universal Digital Indexer} in the 1980s series of Jetsons episodes).

The concept of a freehub was devised and manufactured by British company Bayliss-Wiley in 1938 and won the Cyclists Touring Club (CTC) award for that year. On the Bayliss-Wiley design the freewheel unit was threaded to accept the sprockets. A different four speed design was manufactured by BSA Cycles Ltd in 1949 to accompany their BSA 4 Star derailleur gear. The BSA design had a splined freewheel unit (BSA part No.8-1913) which attached to the hub shell (BSA part No.8-701) and carried four sprockets.

In other words, conventional roller chain drives suffer the potential for vibration, as the effective radius of action in a chain and sprocket combination constantly changes during revolution ("Chordal action"2.2.1 Chordal Action: You will find that the position in which the chain and the sprockets engage fluctuates, and the chain vibrates along with this fluctuation. ). If the chain moves at constant speed, then the shafts must accelerate and decelerate constantly. If one sprocket rotates at a constant speed, then the chain (and probably all other sprockets that it drives) must accelerate and decelerate constantly.

The interactive glide gear system is an extension of hyperglide, in which both sides of the bicycle gear sprockets are physically contoured to improve upshifting. Interactive glide sprockets are slightly thicker than hyperglide variants, and due to this difference, some Shimano Hyperglide chains may hang up if used on an interactive glide cassette. The slightly wider interactive glide chains work on either type, as do SRAM chains. The IG chains are wider internally but narrower externally than the standard HG chains that Shimano made at the same time; the plates of the chains are thinner.

Double Super 8 film (commonly abbreviated as DS8) is a 16 mm wide film but has Super 8 size sprockets. It is used in the same way as standard 8 mm film in that the film is run through the camera twice, exposing one side on each pass. During processing, the film is split down the middle and the two pieces spliced together to produce a single strip for projection in a Super 8 projector. Because it has sprockets on both sides of the film, the pin-registration is superior to Super 8 film and so picture stability is better.
|
|
Suntour — Maeda Industries (Japan) introduced a compact 6 speed freewheel which reduced the spacing between the sprockets and was the same width as a standard 5 speed freewheel but required a narrower chain than the standard. The concept was copied by European freewheel manufacturers Regina (Italy) and Maillard (France). As the number of sprockets on a multiple freewheel increased, clusters became physically wider, and the freehub design overcame the axle/bearing problem with threaded hubs and began to supersede the freewheel design. Today it is rare to find a freewheel on a new bicycle with more than seven speeds.
|
|
Shimano cassette and freehub Cassettes are distinguished from freewheels in that a cassette has a series of straight splines that form the mechanical connection between the sprockets and the cassette compatible hub, called a freehub, which contains the ratcheting mechanism. The entire cassette is held on the hub by means of a threaded lockring. Some cassette systems from the late 1980s and early 1990s use a threaded small sprocket to hold on the larger splined sprockets. Cassettes resemble freewheels when installed, but are clearly different when removed as they do not contain a freewheel's internal ratcheting mechanism.

In a standard film projector, each frame of film is positioned, or registered by being held motionless against a rectangular opening, known as the gate, for a fraction of a second. While in the gate, light passes through the image in the frame, to be projected onto the screen. As soon as the shutter cuts off the light, either sprockets or a device called a claw is used to move the film rapidly so that the next frame can be registered in the gate before the shutter opens again. However, the pins on the sprockets (or the claw) do not fit the sprocket holes in the film perfectly.

Engine timing was controlled by the all-steel, silent Morse timing chain (some early production engines had double-row roller timing sets), which was located beneath the aluminum timing cover at the front of the engine block. The timing chain sprockets, one each for the camshaft and crankshaft, were all-steel; for the last few years the LA engine came with nylon teeth on the sprockets. At the rear of the camshaft was cut a set of helical gear teeth, these being used to spin the distributor. Mounted to the front of the timing cover was a new- design counter-clockwise-rotation water pump, with much improved flow.

Micro drive is a type of bicycle drivetrain, mostly BMX and MTB, that uses smaller than standard-sized sprockets. The smallest rear sprocket that fits on a freehub body is an 11-tooth, but with the use of a cassette hub, sometimes called a micro drive rear hub, sprockets as small as 8 teeth may be used. The advantage of micro drive is that it means a smaller front sprocket, or chainring, can be used without affecting the gear ratio, providing better ground clearance. For example, a bike using a 32-tooth chainring with a 16-tooth rear sprocket can switch to using an 18-tooth chainring and a 9-tooth sprocket, and still have a 2:1 ratio.

A higher gear allows a cyclist to make fewer pedal turns to maintain a given speed, but with more effort per turn of the pedals. With a chain drive transmission, a chainring attached to a crank drives the chain, which in turn rotates the rear wheel via the rear sprocket(s) (cassette or freewheel). There are four gearing options: two-speed hub gear integrated with chain ring, up to 3 chain rings, up to 11 sprockets, hub gear built into rear wheel (3-speed to 14-speed). The most common options are either a rear hub or multiple chain rings combined with multiple sprockets (other combinations of options are possible but less common).

|
This progression has provided more fine adjustment of gear ratio, however the use of thinner metal parts has had the effect of shortening the life-span of the chain and sprockets due to so called "stretching" of the chain. This is caused by frictional abrasion of the load-bearing surfaces of the chain causing elongation. As such, the chain and sprockets of a nine-speed system require more frequent replacement than an eight. The narrowing of the hub flanges has created more dish in the wheel, which weakens the wheel if all other factors are the same, but improvements in the strength and reliability of spokes and rims has more than balanced this out, and wheel strength is generally higher despite the increased dish.

Since cyclists' legs are most efficient over a narrow range of pedaling speeds, or cadence, a variable gear ratio helps a cyclist to maintain an optimum pedalling speed while covering varied terrain. Some, mainly utility, bicycles use hub gears with between 3 and 14 ratios, but most use the generally more efficient dérailleur system, by which the chain is moved between different cogs called chainrings and sprockets in order to select a ratio. A dérailleur system normally has two dérailleurs, or mechs, one at the front to select the chainring and another at the back to select the sprocket. Most bikes have two or three chainrings, and from 5 to 11 sprockets on the back, with the number of theoretical gears calculated by multiplying front by back.

Bicycle chain of the bar-link or block chain type on safety bicycle in a vintage (c1900) photograph However, they have advantages in specific applications, especially where no sprockets are needed, where strength is a greater concern than efficiency (high loads), and where the chain has special fixtures for holding or engaging a load.
|
|
However, they are not as durable when subjected to high horsepower as a chain. You can not alter the length and change final drive ratios as easily as chains. They also can not wrap as closely around as chains. And require larger pulleys compared to chain sprockets to get an effective final drive ratio.

Having carried out necessary modifications, this vehicle was designated Object 305. It's powered by 12-cylinder "V"-layout W-54 engine. The tracked suspensions consists of a pair of drive sprockets located at the front of the vehicle, idler wheels at the rear, six pairs of road wheels and four pairs of return rollers.
|
|
The drive chain powers the rear swiveling two axle truck assembly mounted under the rear frame and platform bed. The drive shaft turns only the forward axle. The rearmost axle is driven by roller chains and sprockets mounted outside of the wheels on each side. The rear truck has twenty four-inch diameter cast wheels.
|
|
This allows the tire to lose some of its grip and slide or lift off the ground completely. Power is transmitted from the engine to the rear axle by a chain. Both engine and axle sprockets are removable. Their ratio must be adapted to the track configuration to obtain the most performance from the engine.

The WZ-111 featured a 750 hp supercharged diesel engine and torsion bar suspension system. The idler wheels were in front with drive sprockets in the rear. Many of the suspension components were the same type used in Soviet heavy tank designs such as the IS-2. The first prototype began testing in 1964.

The Mac version was released in parallel with the PC version. It supported RAVE hardware acceleration as well as 3DFX's Voodoo, built-in software rendering and, later on, OpenGL rendering. RAVE acceleration support allowed the game to support hardware 3D acceleration with just about every Mac that included it. It also supported Apple's Game Sprockets.

The design of the M11/39 was influenced by the British Vickers 6-Ton. This influence is reflected particularly in the track and suspension design. One innovative aspect of the design was the placement of the final reduction gears inside the front-mounted drive sprockets, eliminating the need for enlarged final drive housings in the bow armor.

Noogeez was dreamed up by Ken Starratt as a way to use Bob's older Squalls material in a kid-friendly format. 2 videos have been made so far using this material. Members of this band include Ken and Jorma Starratt, Ken's son. Their first video, "Kathy", won the audience choice award during the 2007 Athfest Sprockets competition.

A fully developed drawing with the Krupp turret was completed, dated 5 March 1941. The Krupp turret would be used on both the Porsche and the Henschel Tiger. Uncommon for tanks at the time, Porsche selected a gasoline-electric drive. The front drive sprockets for the tracks were driven by two electric motors mounted forward in the hull.
|
|
The engine compartment also has an automatic fire-extinguishing system. The running gear consists of 14 (2×7) rubber-rimmed double dished road wheels, two idler wheels (at the front of the hull), two drive sprockets (rear hull) and ten (2×5) return rollers supporting two tracks. The tracks have a service life of approx. 2,500 km.
|
|
The tracks were driven through the front sprockets. There were two return wheels. The suspension had troubles early on, with a tendency to pitch on rough ground, and so it was modified with a brace to connect the pairs of bogies. Despite this, the tank continued to give its users a rough ride across any uneven ground.

Supercharger drive belt in a dragster A toothed belt; timing belt; cogged belt; cog belt; or synchronous belt is a flexible belt with teeth moulded onto its inner surface. It is sometimes designed to run over matching toothed pulleys or sprockets. Toothed belts are used in a wide array of in mechanical devices, where high-power transmission is desired.
|
|
The two motors were mounted in half height in the locomotive frame. Those two motors drove big cogwheels over sprockets spring- loaded on both sides. Each of those big cogwheels drove a jackshaft. The two jackshafts drove a shared slit coupling rod which drove – over a vertical crosshead – the crank pin of the center drive-axle.
|
|
These powered the rear swiveling two-axle truck assembly mounted under the rear frame and compartment. The drive shaft powers only the forward axle, which was made from a modified Ford truck rear axle. The rearmost axle is driven by roller chains and sprockets mounted outside of the wheels. The rear truck has twenty-four inch diameter cast wheels.
|
|
Two motors were mounted in each bogie frame. They were located between the second and third drive-axle. The motors drove big cogwheels in the jackshaft over spring-loaded sprockets. The crank pin of the jackshaft drove over inclined connecting rod a pin mounted on the triangle-shaped coupling rod which connected the first and the second drive- axle.
|
|
Sprockets and chains are also used for power transmission from one shaft to another where slippage is not admissible, sprocket chains being used instead of belts or ropes and sprocket-wheels instead of pulleys. They can be run at high speed and some forms of chain are so constructed as to be noiseless even at high speed.
|
|
These gears were connected with a ladder-type chain connected to their sprockets. The rubber tires, obtained at a hobby shop, were one and a half inches in diameter. The rear axle was one- eighth inch in diameter. The wiring for the solar cells to the electric motor was by standard No. 20 insulated stranded copper wire.
|
|
In the worst case there could be only 10 distinct gear ratios, if the percentage step between chainrings is the same as the percentage step between sprockets. However, if the most popular ratio is duplicated then it may be feasible to extend the life of the gear set by using different versions of this popular ratio.
|
|
The drive sprockets were at the back. Each track was made up of 90 stamped links, each link of 608 mm width. The normal distance between two connected links was 160 mm. There were three internal fuel tanks, two in the crew area and one in the engine compartment, for a total capacity of 600–615 litres.

Efforts have only recently been made to preserve early examples of optical sound. While none of GE's original Pallophotophones are known to exist, a few reels of Pallophotophone recordings of radio broadcasts have been found. Unlike movie film, these 35mm reels do not contain sprockets. New players have been built using modern components to recover audio from old reels.

Shimano 8-speed cassette showing the Hyperglide teeth profiles Hyperglide is the name given by cycling component manufacturer Shimano to a sprocket design in their bicycle derailleur tooth cassette systems. It varies gear tooth profiles, and/or pins along the faces of freewheel or cassette sprockets, or between the chainrings in a crankset, to ease shifting between them.

All models are intended for off-road trail use. Although the target audience for the motorcycle is the youth and small adult market, it is also available in "L" version which feature larger front and back wheels and sprockets, designed to accommodate larger adult riders. The "L" version is also equipped with hydraulic disc brakes in the front.

A film synchronizer is a device used in the editing phase of filmmaking. Film synchronizers generally have 1 to 8 "gang(s)", or slots through which film can be threaded. Each gang consists of a group of large diameter sprockets on a common shaft. A rotating knob on the front, which moves the threaded film through the gangs, operates the synchronizer’s movement.
|
|
A less common type of breech is the split-breech design known as the "nutcracker". This type of breech consists of two counter-rotating sprockets, with a temporary breech being formed where they touch. Relatively few guns have used this design. The prototype Fokker-Leimberger multiple-barreled machine gun used this design, but it had numerous problems with ruptured cases.

Timing belts, toothed belts, cogged or cog belts,in Contact !, Experimental Aircraft and Powerplant Newsforum for Designers and Builders, n°55, Dieselis Aircraft, A Prototype Aircraft with a Diesel Engine and synchronous belts are non-slipping mechanical drive belts. They are made as flexible belts with teeth moulded onto their inner surface. The belts run over matching toothed pulleys or sprockets.

These vehicles served until the end of the war. A significant amount of the original French- made parts, from both the original and converted R-35 tanks, was replaced by Romanian-produced spares in 1941-1942. Romanian factories produced drive sprockets, drive shafts, tracks, new metal-rimmed road wheels and cylinder heads. The wheels were designed locally to be ten times more durable.

The Roux, Combaluzier & Lepape lifts during construction. Note the drive sprockets and chain in the foreground. Equipping the tower with adequate and safe passenger lifts was a major concern of the government commission overseeing the Exposition. Although some visitors could be expected to climb to the first level, or even the second, lifts clearly had to be the main means of ascent.

This was an exceedingly expensive piece of electronic and was more than their £500 budget. However, Brown managed to scrounge a damaged component and repair it. The machine was built on top an old hospital bed and made extensive use of Meccano chains and sprockets. By late 1957 the first contact B-mode scanner was constructed and in clinical use by that year.

After high school in Poitiers, Gérard Patris joined an art school in Paris. Early into his career, Patris founded a workshop in Paris in lithography. The job allowed him to meet many of the major artists of the post-war period for the attainment of prints as Dubuffet, Sprockets, Manessier, Sonderborg, Arman, Hayter, Hartung or Matta. Gérard Patris had two daughters from different partners.

However, the machine only had two carburetors, each of which had to feed two cylinders via Y-shaped manifolds. They used shaft drive, eliminating the possibility of chain lube getting on the rear tyre, but torque reactions on the opening and closing of the throttle. In addition, the adjustment of the gearing was very difficult. With a chain drive it was easy to replace the sprockets.

Bicycle rear derailleur pulley wheels Although variations exist, most dérailleurs used for changing between the cassette of sprockets - or Cogset - on the rear of a road (race) bicycle or MTB (mountain bike) (collectively known as the gears) have several components in common. These include the jockey wheels which are held in situ inside a precision-machined vertical cage via steel or ceramic bearings. This cage holds two guide pulleys that locate the chain, almost always in a vertically positioned S-shaped pattern (an 'S' in reverse when viewed from the bike's drive-side). The pulleys are known collectively as the jockey wheels or jockey pulleys - the guide pulley is at the top of the pairing (closest to the sprockets) and the tension pulley is at the bottom, taking any slack up from the bike chain as it is fed from one of the chainset's chainring.

The rake is 25°, trail is , wheelbase is , and seat height is . It has a tested dry weight (minus fuel only) of and a tested wet weight of . The chain drive is a 530 chain with stock gearing of 16 tooth front and 43 tooth rear sprockets. A carburetted version exists in the form of the CB600F, known as the Hornet 600 in Europe and the 599 in North America.

|
The track now had to be supported by five top rollers. The overlapping system as such was maintained in all prototypes; with smaller wheels it allowed for nine instead of the originally planned eight wheels, five forming the outer, four the inner row. The engine and transmission system was in the rear of the vehicle with rear drive sprockets. The transmission was derived from the ZF of the Panther.

Any standard 35mm still-film (135 format) may be used with a few caveats: Polaroid 35mm instant film shouldn't be used because "winding problems may occur"; infrared film is not recommended because the frame counter shines infrared light at the sprockets (this is a very common feature with motorised film-advance cameras); the camera can't advance beyond the 40th frame in rolls of film with more than 40 frames.
|
|
The FZ750 uses a six-speed sequential close ratio gearbox; the gear shafts are only removable by splitting the crankcase halves. The clutch is of the wet, multi-plate type and is hydraulically operated. Final drive is by O-ring chain and sprockets. A safety feature of the FZ750 is that the engine ignition is cut if first gear is selected with the sidestand down; this is commonplace on modern motorcycles.

Gashing is a machining process used to rough out coarse pitched gears and sprockets. It is commonly used on worm wheels before hobbing, but also used on internal and external spur gears, bevel gears, helical gears, and gear racks. The process is performed on gashers or universal milling machines, especially in the case of worm wheels. After gashing the gear or sprocket is finished via hobbing, shaping, or shaving..
|
|
The four wheels shared drive and idler sprockets with the track, and the move from wheels to track, and vice versa, could be made from within the hull. In 1943 the improved design prototype was shipped to Britain, where it was evaluated by the Department of Tank Design. Although not completely critical, the project was advised to be stopped. The tank was stored for a while and scrapped after the war.

As an interlude, or at the start of the broadcast day, there were showings of a film magazine programme called Sprockets (not to be confused with the SNL sketches with Mike Myers). In under a year, the channel and EPG slot was sold to Dolphin Television who rebranded it as a 24-hour channel called Movies4Men on 1 February 2006. Sit-Up have no involvement with this channel.

Field tests showed various drawbacks of the entire design (the recoil was too strong for many components: it damaged drive sprockets, ripped the gear-box away from its mountings, etc.) and the sheer length rendered it incredibly difficult to transport. Its development continued until 1960, when the idea of such overpowered guns (along with the 2A3), was abandoned in favor of tactical ballistic missiles, such as the 2K6 Luna.

In 1914 it introduced the Rex brand-name, which was first used on a chain-driven concrete mixer. It soon became a widely recognized trademark. In 1941 it won the combined Army and Navy Award for Excellence in War Production. By 1943 it was manufacturing: Rex Chain, Rex Concrete Mixers, Rex Sprockets, Rex Traveling Water Screens, Rex Elevators, and Rex Conveyors and was working on conveyor for chemicals.

In 1956, the Renak brand was protected for the VEB Renak works (Reichenbacher hubs and coupling plants). The mid-1960s, the production of bicycle parts reached a peak with exports to 40 countries, but it was throttled and stopped the export. On July 1, 1990, the transformation to RENAK-Werke GmbH took place. Products such as steering bearings, bottom bracket, idler sprockets and unbraked steel hubs have been discontinued.

Before the 1990s many manufacturers made derailleurs, including Simplex, Huret, Galli, Mavic, Gipiemme, Zeus, Suntour, and Shimano. However, the successful introduction and promotion of indexed shifting by Shimano in 1985 required a compatible system of shift levers, derailleur, sprockets, chainrings, chain, shift cable, and shift housing. Today the three main manufacturers of derailleurs are Shimano (Japan), SRAM (USA), and Campagnolo (Italy), although Campagnolo only makes equipment for road and cyclocross.

The final 16mm spool loading Ciné-Kodak, the K100, arrived in 1956 with both turret and non-turret versions. The mid-1930s saw the beginning of a line of magazine-loading cameras, the Magazine Ciné-Kodaks, made initially in Kodak's Nagel Works in Germany. The 16mm Ciné-Kodaks were well-made, long-lived cameras. Most have double claws and double sprockets and hence require double perf (2R) film in unmodified form.

The American T69 resembled the AMX 50 The hull was equipped with a torsion bar suspension designed to ensure a vehicle with good cross-country mobility. The hull and suspension recalled both the German Tiger and the Panther tanks which, having entered French service after the war,Jeudy (1997), p. 207 were well known and deliberately imitated. Especially the engine deck, the sprockets and the tracks are strongly reminiscent of the German design style.
|
|
Another advantage is the reduction in weight with the reduction in size of all the parts. The disadvantage is increased stresses on the drive train, leading to increased wear and even premature failure. As the front and rear sprockets become smaller, the tension in the Chain increases, and stretching and breaking can occur more easily. Designers can overcome these issues by choosing materials with higher yield strengths, however usually at higher costs.

The rider started the engine by pedaling bicycle style pedals with a chain drive and sprockets to the rear wheels. The 1905 model had a high-tension Bosch magneto ignition, a spray carburetor, and a rear coaster brake operated by the pedals. It had a 5:1 reduction ratio to 26-inch wheels. By 1908, it had a two speed transmission with a plate clutch, overcoming the speed limitations of the earlier model.

The chassis of the SU-152G was based on that of the SU-100P self-propelled anti- tank gun, and consisted of 6 pairs of rubberized support and three pairs of supporting rollers. On the rear part of the vehicle the guide wheels were installed, while the driving sprockets were mounted on the front. The tracks consisted of small links with rubber-metal forged hinges. Each track measured 412 by 133 millimeters.

Exhaust gases were handled either by a cast-iron manifold or a fabricated tubular header, depending on application. The original in-block camshaft was retained and, as in the original 116E, drove the side-mounted distributor and nearby external oil pump/filter assembly, minimizing modifications to the mass-produced iron block. The original cam along with the DOHC cam sprockets were driven by a long front- mounted, single-row ⅜-inch Reynolds roller timing chain.

Two motors were mounted in each bogie frame. The motors drove large cogwheels via spring-loaded sprockets on each side, and the cogwheels drove a jackshaft. The crank pins of the jackshafts drove – via a coupling rod – the crank pins of the two outer drive axles of the bogie. The inner side of this coupling rod contained a pin, which drove the crank pins of the two inner drive axles via a second coupling rod.

This was measured in place by a sine/cosine potentiometer that was used to calculate the position of the transducer from the angle of its rotations. This was an exceedingly expensive piece of electronic kit and cost more than their £500 budget. However, Brown managed to scrounge a damaged component and repaired it. The machine was built on top an old hospital bed and made extensive use of Meccano chains and sprockets.

The song "The Telephone Call" (German version: "Der Telefon-Anruf") is notable for being the first and only Kraftwerk song to feature Karl Bartos on lead vocals. The album closes with the title track "Electric Café", which features French-language lyrics. The track gained some exposure in the United States when it was used slightly sped up as the theme song for "Sprockets", the German television spoof by Mike Myers on Saturday Night Live.

In reality, many gears overlap or require the chain to run diagonally, so the number of usable gears is fewer. An alternative to chaindrive is to use a synchronous belt. These are toothed and work much the same as a chain—popular with commuters and long distance cyclists they require little maintenance. They can't be shifted across a cassette of sprockets, and are used either as single speed or with a hub gear.

One fuel tank was located on each side of the engine. The transmission had four forward gears and one reverse gear to drive the front- mounted drive sprockets. The suspension was an enlarged and modified version of that used in the Carden-Loyd tankettes. It consisted of two small road wheels fastened together on a frame, two frames paired and sprung by leaf springs that made a wheel carrier, two wheel carriers per side.

It was constructed in 1969 and designated Ob'yekt 219 SP1. It was renamed the T-64T, and was powered by a GTD-1000T multi-fuel gas turbine engine producing up to 1,000 hp (746 kW). During the trials it became clear that the increased weight and dynamic characteristics required a complete redesign of the vehicle's caterpillar track system. The second prototype, designated Ob'yekt 219 SP2, received bigger drive sprockets and return rollers.

The Wayne Campbell character was featured extensively in the 1986 summer series It's Only Rock & Roll, produced by Toronto's Insight Production Company for CBC Television. Wayne appeared both in-studio and in a series of location sketches directed and edited by Allan Novak. Myers wrote another sketch, "Kurt and Dieter", co-starring with Second City's Dana Andersen and also directed by Novak, which later became the popular "Sprockets" sketch on Saturday Night Live.

There are two chainrings whose relative difference (say 10%) is about half the relative step on the cogset (say 20%). This was used in the mid-20th century when front derailleurs could only handle a small step between chainrings and when rear cogsets only had a small number of sprockets, e.g. chainrings 44-48 and cogset 14-17-20-24-28. The effect is to provide two interlaced gear ranges without any duplication.

The IBM 1627 was a rebranded Calcomp plotter sold by IBM for use with the IBM 1620, and, later, the IBM 1130 computers. It became perhaps the first non-IBM peripheral that IBM allowed to be attached to one of its computers. The plotter fed a roll of paper with perforated edges over a drum with matching sprockets at the sides. The drum could move the paper forward and backward (the X-axis).

It is more about preparing one's supply chain to be flexible for any kind of problem that the market throws at you. Simply having an abundance of suppliers does not mean that one has supply chain diversity. Each supplier must provide similar and/or equal products and be distinguishiably competitive in such a way that each supplier is mutually exclusive under certain conditions. That is to say, supplier Alpha and supplier Beta both sell identical sprockets.

Long used for home movies before the video camera, this uses double sprocketed 16 mm film, which is run through the camera, exposing one side, then removed from the camera, the takeup and feed reels are switched, and the film run through a second time, exposing the other side. The 16 mm film is then split lengthwise into two 8 mm pieces that are spliced to make a single projectable film with sprockets holes on one side.

The film lost to The Girl with the Dragon Tattoo. Siwe, however, won the Guldbagge Award for "Best Director", and Anki Lidén (Jenna's grandmother) was awarded with "Best Actress in a Supporting Role". The film also won awards at international festivals, including the Canadian "Students Choice Award" at Sprockets Toronto International Film Festival for Children and the Norwegian "Don Quijote Award" at Kristiansand International Children's Film Festival. Glowing Stars debuted in second place on the Swedish box office chart.

In university, Doron was awarded two Norman Jewison Filmmaker Awards for her class assignments. One of the projects was her thesis film Simulacrum, which she wrote and directed. This short film also won Best Student Film at the International Festival of Cinema and Technology in 2002 and was part of the Official Selection at Sprockets Toronto International Film Festival For Children, Cleveland International Film Festival, and Leeds Underground Film Festival. Doron has one son, who was born in 2011.

This would later become the Sherman. The Sherman's reliability resulted from many features developed for U.S. light tanks during the 1930s, including vertical volute spring suspension, rubber-bushed tracks, and a rear-mounted radial engine with drive sprockets in front. The goals were to produce a fast, dependable medium tank able to support infantry, provide breakthrough striking capacity, and defeat any tank then in use by the Axis nations. The T6 prototype was completed on 2 September 1941.

A used Shimano chainring, detached from right crank Chainrings (also called "chain rings", "chainwheels" or "sprockets", although sprocket is used this way mostly in the BMX community) engage the chain to transfer power to the (usually rear) wheel. They usually have teeth spaced to engage every link of the chain as it passes over; however, in the past, some designs (called skip-tooth or inch-pitch) have had one tooth for every other link of the chain.

Films included Tomboy starring Betsy Russell, Glen and Randa, Plan 9 from Outer Space and Revenge of the Cheerleaders starring David Hasselhoff. The channel also featured introductions by Paul Ross and episodes of Sprockets. As per Matinee Movies, the channel and EPG slot was also sold to Dolphin Television who rebranded it as a 24-hour channel called ACTIONMAX (later rebranded as Movies4Men 2) on 1 February 2006. Sit-Up have no involvement with this channel.

Below is a list of the three largest manufacturer's groupsets for Road and MTB applications. Each manufacturer's offering is arranged in descending price/quality. The number of sprockets of the cassette in each groupset is shown in brackets. The total number of gears is determined by this number multiplied by the number of chainrings, for example a bike that has a double chainring and a 10-speed cassette has 20 gears, although some of them overlap.

66–67 The Škoda T-11/0 four-cylinder, water-cooled engine produced at 1,800 rpm. Two fuel tanks were fitted, the main tank with a capacity of was on the left side of the engine and the auxiliary tank was on the other side. The engine could run on gasoline, an alcohol-gasoline mixture, and "Dynalkohol" (an alcohol-benzole mixture). It was mounted in the rear along with the six-speed transmission which drove rear-mounted drive sprockets.

The steering system was set up so that shallow turns used only the wheels, but brakes would be applied to the tracks the farther the steering wheel was turned. The drive sprockets had rollers rather than the more common teeth. The rear suspension consisted of six double roadwheels, overlapping and interleaved in the Schachtellaufwerk system, mounted on swing arms sprung by torsion bars. An idler wheel, mounted at the rear of the vehicle, was used to control track tension.

When encoded utilizing Dolby Laboratories' technology (itself originally being in part licensed from Sansui), the discrete L and R channels of Westrex's stereo variable-area system were renamed "Left Total" and "Right Total", and when decoded utilizing Dolby's Cinema Processor these produced the L, C, R and S sound image first commonly used by Fox's CinemaScope magnetic stereo system in 1953. Stereo optical sound prints are compatible with films with any aspect ratio and with normal print film stocks with KS-type film perforations, whereas stereo magnetic sound prints require film stocks with the narrower CS-type film perforations. Film with CS-type perforations can only be run on a projector fitted with special narrow-toothed sprockets or permanent damage will be done to the film. An alternative is LaVezzi's VKF ("Very Kind to Film") sprockets, which perform optimally on KS- as well as CS-perforated prints. Stereo variable-area, therefore, provided for the first time stereo film prints of any aspect ratio (1.37:1/Academy through 2.35:1/CinemaScope, inclusive) which could be run without damage on any normal 35mm cinema projector.

Small budget motorcycles may have a totally enclosed drive chain, but this is rare on larger motorcycles, an exception being the Norton rotary bikes. To prevent rapid wear of the chain and sprockets, it is customary to apply a greasy chain-lube via an aerosol. Many riders also fit aftermarket chain-oilers to feed a regular supply of oil to the chain at the rear sprocket. These chain oilers vary in sophistication, but all add significantly to the life of the chain.

The drum shell (or pulley face) can be produced in aluminium, steel or stainless steel and is normally crowned to facilitate central belt tracking. However, cylindrical shells can be produced and fitted with external sprockets or rotary brushes for special applications. Rubber NBR, PU and other coatings can be applied to the shell to increase friction between the shell and conveyor belt and hot vulcanised or moulded profiled lagging can also be applied to drive plastic or steel modular belts.

Renault called on Amédée Gordini to produce a supertuned version of the Renault Dauphine: The Dauphine 1093 (type R1093), a sporty derivative of the Dauphine which appeared at the end of 1961. The modifications mainly concerned the engine. It used pistons with convex heads (compression ratio increased to 9.2:1), a reversed Solex twin-choke carburetor type 32 PAIA 3, a special camshaft, double valve springs and Autobleu intake manifolds and exhaust. The sprockets were reinforced as well as the clutch.
|
|
A few more sprockets are usually added to the front assembly as well. Multiplying the number of sprocket gears in front by the number to the rear gives the number of gear ratios, often called "speeds". Hub gears use epicyclic gearing and are enclosed within the axle of the rear wheel. Because of the small space, they typically offer fewer different speeds, although at least one has reached 14 gear ratios and Fallbrook Technologies manufactures a transmission with technically infinite ratios.

The timing chain was hydraulic tensioned and had a ratchet mechanism to keep the chain tight. The timing chain rode on one pivoting chain guide resting on the ratchet tensioner and one fixed guide attached to the engine block and cylinder head. The 1991 to 1998 DOHC engine had an upper timing chain guide in between the camshaft sprockets. The timing chain was lubricated via cast-off from the top of the cylinder head and one 'squirter' on the oil pump housing.

769 In 1899 the company offered an interesting but complicated steam car. It featured runabout coachwork and was powered by three small single-cylinder steam engines built into each of its rear wheel hubs in a way that they worked as a radial engine. It was tried to avoid the use of sprockets, chains and a differential gear as each wheel worked completely independent from the other.The Horseless Age, December 1899 issue The vehicle could reach a maximum speed of .

The Omni-Phase balance system consumed some engine power to operate. In early production models sold in Japan, Yamaha used a spring-loaded chain- tensioner to control lash on the chain driving the Omni-Phase balancer, but this was later changed to drive sprockets with a 1 mm offset which controlled chain lash while offering longer chain life and reduced noise. Both kick-start and electric-start were standard. The electric start added a third chain to the engine's internals.

10-speed bicycle cassette On a bicycle, the cogset or cluster is the set of multiple sprockets that attaches to the hub on the rear wheel. A cogset works with a rear derailleur to provide multiple gear ratios to the rider. Cogsets come in two varieties, freewheels or cassettes, of which cassettes are a newer development. Although cassettes and freewheels perform the same function and look almost the same when installed, they have important mechanical differences and are not interchangeable.
|
|
This allows different brands of freewheels to be mounted on different brands of hubs. The major disadvantage of the multiple sprocket freewheel design is that the drive-side bearing is located inboard of the freewheel, and as sprockets were added over time, moved the bearing farther from the drive-side axle support. This resulted in more flexing stress being placed on the axle, which can bend or even break. Multiple speed freewheels were common on quality high end bikes until the late 1980s.

1986-2004 Models: A1-A13/B1-B12 The A and B model denotes whether or not the bike has been restricted down to a power output deemed necessary for a learner with a provisional drivers license in some countries or an A1 motorcycle license in the United Kingdom, The "A" models, running from 1986 to 2001 came from the factory in a unrestricted form, producing 20 bhp at the rear wheel easily reaching 85 mph with some modifications to the gearing ratio (sprockets).

The Sd.Kfz. 250 also inherited the track- sparing but more complicated rollers in place of the more commonplace toothed sprockets. The track ran on four double roadwheels overlapping and interleaved in the so-called Schachtellaufwerk design used by nearly all German half- tracked vehicles, mounted on swing arms sprung by torsion bars, track tension being maintained by an idler wheel, mounted at the rear. The front wheels had transversely mounted leaf springs and shock absorbers (the only ones fitted) to dampen impacts.

The drive sprockets are in the front and driven by a transmission in the nose of the vehicle. The two crew members, the driver on the left, sat in the forward compartment, the drive shaft between them. Entrance to the compartment is by two wide horizontal hatches, the upper hinging upwards, allowing the driver an unobstructed view if opened, the lower hinging downwards. The centrally positioned engine compartment is separated by a bulkhead from the driver compartment in front of it.

A three-day weekend pass was awarded to the designer of the winning entry. Linthwaite won the contest: he designed a circular patch, four inches in diameters, with a solid yellow- gold background to symbolize the Cavalry heritage. On the face of the patch, he drew a stylized black tank track with a drive and idler sprockets to symbolize mobility. In the center of the track at a slight diagonal, he placed a single cannon barrel, also in black, to symbolize firepower.

Enthira Kaalai Enthira Kaalai is a sculpture created by students of the Society Of Mechanical Engineers (SOME) and Department of Mechanical Engineering, Nandha Engineering College. It was inspired by the Tamil Nadu culture and festival, namely Jallikattu. The sculpture was assembled from scrap materials; bike sprockets, gears, spark plug, chain, sheet metal, wire spring, bearing, nut-bolts, pistons, connecting rods, and mild steel pipe. The skeleton of the structure was built with mild steel square rods and mild steel flat sheet metal.

Close up of the MK 38 naval variant Unlike most automatic firearms, the M242 does not depend on gas or recoil to actuate its firing system. Instead, it uses a DC motor, positioned in the receiver to drive the chain and dual-feed system. This system uses sprockets and extractor grooves to feed, load, fire, extract, and eject rounds. A system of clutches provides for an alternate sprocket to engage and thus allows the gunner to switch between armor-piercing and high- explosive rounds.

They are connected to the torsion bars on swing arms, whose deflection is limited by volute springs. Drive is through the drive sprockets located at the rear. The Rubber-mounted shocks were modified to achieve better stability during firing. The track is manufactured by the company Diehl, rubber track pads fitted, and is "live" track with rubber bushings between the track links and pins (type: D 640 A). Grouser/icecleats can replace the rubber pads on some track links to increase traction on slippery surfaces.

The title was won by Peterborough Pumas the junior side belonging to Peterborough Panthers. The majority of the clubs were the junior sides belonging to their respective senior side or a collaboration ran by their senior sides. The Raven Sprockets were a combination of the Reading Racers and Swindon Robins, the Western Warriors were a combination of the Exeter Falcons and Newport Wasps, the Shuttle Cubs were Wolverhampton Wolves and Long Eaton Speedway and finally the Anglian Angels were the Ipswich Witches and Rye House Rockets.

Some new single-speed — especially BMX and utility bikes — and lower-end multi-geared bicycles continue to be manufactured and sold with freewheels. Pedaling forces tighten a freewheel onto the hub, so no tool is required to install one. The ratcheting mechanism prevents the freewheel being loosened when the sprockets are turned counter-clockwise. A freewheel can be removed from the hub with one of the many specific freewheel removal tools that engages a spline or set of notches on the outboard end of the freewheel.

Shift ramps are complex tooth profiles, in the rear sprockets and front chainrings, designed to pick up and drop the chain during shifting. They allow for shifting under greater load than was previously possible, and for smoother and cleaner shifting. The different systems are branded Hyperglide by Shimano, UltraDrive by Campagnolo, and OpenGlide by SRAM. The chain itself is specifically manufactured for ease of shifting, and to interface with a particular manufacturer's shift ramps; using a different type of chain may result in sub-optimal shifting.

However, many details have been improved, especially since the advent of modern materials and computer-aided design. These have allowed for a proliferation of specialized designs for many types of cycling. The bicycle's invention has had an enormous effect on society, both in terms of culture and of advancing modern industrial methods. Several components that eventually played a key role in the development of the automobile were initially invented for use in the bicycle, including ball bearings, pneumatic tires, chain-driven sprockets and tension-spoked wheels.

The 10TP tank had a wide hull that made it possible to put two members of the crew inside side by side, a front machine gun and a two-man turret. A solution to the problem of driving the vehicle both on wheels and tracks followed the American design, however Polish designers developed new, wider tracks, drive sprockets and a way of link hooking and moving. The tank steering system using hydraulic servomechanisms was their own advanced solution significantly affecting combat performance of the whole vehicle.

Magnetic soundtracks are essentially the same as used in conventional analog tape recording. Magnetic soundtracks can be joined with the moving image but it creates an abrupt discontinuity because of the offset of the audio track relative to the picture. Whether optical or magnetic, the audio pickup must be located several inches ahead of the projection lamp, shutter and drive sprockets. There is usually a flywheel as well to smooth out the film moves to eliminate the flutter that would otherwise result from the negative pulldown mechanism.

When a rider operates the shifter while pedalling, the change in cable tension moves the chain-guide from side to side, "derailing" the chain onto different sprockets. The rear derailleur also has spring- mounted jockey wheels which take up any slack in the chain. Most hybrid, touring, mountain, and racing bicycles are equipped with both front and rear derailleurs. There are a few gear ratios which have a straight chain path, but most of the gear ratios will have the chain running at an angle.

Stereo Realist Red Button viewer with slides The Realist uses standard 135 film. The unusual proportions of the slides (the image was 5 sprockets wideStereo Realist Manual, p. 43.) became the standard for 3-D slides, and is known as "5P" or "Realist Format". It marked a significant milestone in stereoscopy. The arrangement of images on the film (on cameras where film advances left to right 1R-blank-2R-1L-3R-2L-4R...) seemed arbitrary but allowed for a simple film advance mechanism with little film wastage.

He taught mathematics in Pisa from 1635 to 1655, after Vincenzo Renieri; in 1635 Michelini also taught astronomy to Leopoldo de' Medici. He was then vicar of the Bishop of Patti, Sicily and he became the mathematician of Cardinal Leopoldo de' Medici, who financed his research. Famiano Michelini was the first scientist to hypothesize a theory on active defense against corrosion of the river banks through the use of sprockets and he was never invited to the Cimento Academy. He died in Florence in 1665.

Over time, the number of sprockets in a cogset has increased, from three or four before World War II, to five used from the 1950s to the 1970s, up to the eight, nine, ten, eleven, or twelve now found on modern bikes. As more rear sprockets were added, the combination became wider, and the sprocket spacing narrower. One of the ways to make space for this was the axle length (measured as the Over Locknut Distance — O.L.D.) was increased, necessitating more dish on the rear wheel drive side with a threaded hub to centre the wheel in the frame. The hub flanges spacing was not shortened on threaded hubs, rather the axle length increased from 120 mm O.L.D. (five-speed/compact six) to 126 mm O.L.D. (six-speed/compact seven) through to 130 mm O.L.D. (threaded seven-speed) for a road bike. MTB rear spacing is normally 135 mm O.L.D. Another advantage of the Shimano cassette hubs introduced from 1978 was that the rear hub flanges were wider apart than those of a threaded hub, so built a stronger wheel with less dish and without the problem of increased bearing stress or axle failure.

As with motion picture cameras, the intermittent motion of the gate requires that there be loops above and below the gate in order to serve as a buffer between the constant speed enforced by the sprockets above and below the gate and the intermittent motion enforced at the gate. Some projectors also have a sensitive trip pin above the gate to guard against the upper loop becoming too big. If the loop hits the pin, it will close the dousers and stop the motor to prevent an excessively large loop from jamming the projector.

This provides nearly the same lower gear ratios as a triple but without the need for a third chainring, a triple front derailleur and a long cage rear derailleur. Both Shimano and Campagnolo recommend and sell front derailleurs specifically designed for compact cranksets, claiming better shifting. Compact gearing is not necessarily lower than standard gearing if cassettes with smaller sprockets (such as 11–23) are used. A high gear of 50×11 on a compact drivechain is actually slightly higher than the 53×12 of a standard set.

The Tagash AVLB has supported the IDF in the Yom Kippur War, 1982 Lebanon War, 2006 Lebanon War and the 2014 Israel-Gaza Conflict. The IDF continues to use the M60A1-based bridge layers except with modifications. Vehicle modifications included new all-steel Merkava tracks and drive sprockets, although some vehicles continue to use the original T142 track. Due to the growing use of a number of trenches in fortifications and the greater number of natural narrower obstacles rather than larger ones, a tandem assembly bridge called the Tzmed or tandem was engineered.

For the strike, the installation consisted of a RPH50AC motor and Mark II winder weighing approximately 40 pounds with overload protection and regulator. A 16-tooth split chain and 35 feet of one-half-inch pitch roller chain with idler and chain adjuster. The clock was also cleaned and repainted with the internal dial re-lacquered. The work was carried out by the inventor of the system, David Gamble of Eaton Socon and consists of a small electric motor clamped to weights and geared with sprockets onto a continuous chain.

The candy stick is first bent to a right angle as it is moved past and put into contact with an inclined face. The patent application describes two potential versions of the mechanism which complete the bending process. The first version of the mechanism has a chain around two sprockets on which are mounted bending rollers. Each bending roller is attached to a cam which rides along another inclined face to move the roller along the protruding surface of the cane to complete bending it around the die.

When the high wheeler or penny-farthing was the "ordinary" bicycle form, the comparative diameter in inches of the driven wheel was an indication of relative speed and effort. A 60-inch wheel propelled a bicycle faster than a 50-inch wheel when both were cranked at the same cadence. The technology of the high wheeler imposed a natural limit—a 60-inch wheel was about the maximum size that could be straddled by ordinary sized legs. When "safeties" replaced "ordinaries," chains and sprockets allowed small wheels to be turned faster than the pedal cranks.

The vehicle was powered by one of Fuhrmann's earlier projects, the Type 547 engine. This 1.5 litre air-cooled four-cylinder boxer engine had four camshafts; two per cylinder head. The exhaust camshafts were driven by layshafts that took power from a countershaft in the central crankcase below the crankshaft, while the intake camshafts were driven by vertical shafts from the exhaust camshafts, all of which was tied together by an assortment of sprockets and bevel gears. The engine also had two sparkplugs per cylinder, powered by a dual ignition with two ignition coils.

Bissette is best known for his multiple award-winning collaboration with writer Alan Moore and inker John Totleben on DC Comics' Saga of the Swamp Thing (1983–1987). Under the company name of Spiderbaby Grafix, he later published the horror anthology Taboo, the original home of Moore and Eddie Campbell's From Hell and Tim Lucas' Throat Sprockets illustrated by Mike Hoffman and David Lloyd. He created Tyrant, a comic book biography of a Tyrannosaurus rex, which lasted four issues. During this period, he edited the horror anthology Gore Shriek, published by FantaCo Enterprises.

Some systems combine internally geared hubs with external derailleurs. A freewheeling hub with a sprocket suitable for narrow chain can be combined with a double or triple crankset and front derailleur, in order to provide a wider range and closer gear ratio spacing. A chain tensioner or a rear derailleur is needed to take up chain slack, and care is needed not to over- torque the hub by using too small a chainring/sprocket ratio. Alternatively, some hubs can accept two dished drive sprockets, between which the rider can switch with a rear derailleur.

Due to their unique nature, beach races tend to be very popular with riders and spectators, with some of the larger races attracting several hundred riders. However beach racing is known to be very tough on motorcycles, small sand particles can damage wheel bearings, chains and sprockets, and the soft, sandy surface increases the demand on engines and clutches. Experienced beach racers typically follow meticulous bike maintenance prior to the event in order to ensure their bike will not fail. Beach races are generally held in early spring or late autumn.

He started his long career in film processing at the industry's infancy in 1907, a time before cameras and projectors had sprockets and film had holes to match in order to assure a constant film flow, and steady exposed and projected image. Safety film, sound, and color reversal film stocks had not been conceived. And it was a time before continuous processing; when movie film was loaded on racks, batch processed in dip tanks and dried in drums. His first industry job was with the Wendel film processing laboratory in Manhattan.

RD500LC rear view The RD500LC uses a six-speed sequential close ratio gearbox with the usual road-going 'one down and five up' sequence, the gear shafts are removable from the right side of the engine without the need to split the crankcases. The clutch is of the wet, multiple-disc coil spring type and is cable operated. Unusually for a two-stroke engine the gears and outer crankshaft bearings are lubricated by a separate crankshaft driven troichoid oil pump. Final drive is by conventional for the time O-ring chain and sprockets.

The M11/39 was developed as a "breakthrough tank" (). The design of the M11/39 was influenced by the British Vickers 6-Ton. This influence is reflected particularly in the track and suspension design. A novelty of the design was the placement of the final reduction gears inside the front-mounted drive sprockets, eliminating the need for enlarged final drive housings in the bow armour. Service use of the M11/39 was short due to several deficiencies in its design, particularly the placement of the main 37 mm gun in the hull.

The short "movies" presented on the early Kinetoscopes had little variety, and they rapidly wore out. As Joly became aware of these shortcomings, he offered to make a camera for Pathé that could be used to reproduce the Kinetoscope films. Pathé agreed to fund the development, and on 26 August 1895, Joly filed a patent application for a camera that could provide films both for a projector and for the Kinetoscope. The camera used a mechanical movement similar to that in the Demenÿ system, and utilized perforated film which could be advanced on mechanical sprockets.

High normal or top normal rear derailleurs return the chain to the smallest sprocket on the cassette when no cable tension is applied. This is the regular pattern used on most Shimano mountain, all Shimano road, and all SRAM and Campagnolo derailleurs. In this condition, spring pressure takes care of the easier change to smaller sprockets. In road racing the swiftest gear changes are required on the sprints to the finish line, hence high-normal types, which allow a quick change to a higher gear, remain the preference.

The standard Edwards Rail Car was designed and recommended for branch line service where traffic requirements are within its capacity, for high speed operation, on roadbeds where the grades are not too severe. Three types of propulsion systems, mechanical, Diesel-electric or hydrostatic driven were available. The mechanically driven car employs the use of engine, transmission, final drive gear box with sprockets and chains to deliver power to the driving wheels. Cars equipped with electric propulsion have an engine which turns a generator for providing electricity for the traction motors.

Roller chain and sprockets is a very efficient method of power transmission compared to (friction-drive) belts, with far less frictional loss. Although chains can be made stronger than belts, their greater mass increases drive train inertia. Drive chains are most often made of metal, while belts are often rubber, plastic, urethane, or other substances. Drive belts can slip unless they have teeth, which means that the output side may not rotate at a precise speed, and some work gets lost to the friction of the belt as it bends around the pulleys.

Lambert automobile from 1906 with the friction drive revealed. A friction drive or friction engine is a type of transmission that utilises two wheels in the transmission to transfer power to the driving wheels rather than a chain and sprockets system. This kind of transmission is often used on scooters, mainly go-peds, in place of a chain. The problem with this type of drive system is they are not very efficient, since the output wheel (leather covered wheel) has width, the area of contact is spread across various radii on the primary disc.

A 50-horsepower steam engine provided power for the drop hammers and other equipment. The fathers of the founders were both managers at the Crompton Loom Works and helped their sons' business win contracts for the crankshafts and for pistol and micrometer components. The company won contracts from railroads for automatic couplers and from bicycle manufacturers for sprockets, spindles, and pedals, having gained a reputation for the high quality of its early work. From around 1902, it also began filling orders for crankshafts from manufacturers of the recently invented automobile.

Replacement parts (roadwheels, armor skirt panels, drive sprockets, etc.) are painted olive green, which can sometimes lead to vehicles with a patchwork of green and desert tan parts. Australian M1A1s were desert tan when delivered but have undergone a transition to the Australian Army vehicle standard 'Disruptive Pattern Camouflage'; a scheme that consists of black, olive drab, and brown. The U.S. Army can equip its Abrams tanks with the Saab Barracuda camouflage system, which provides concealment against visual, infrared, thermal infrared, and broad-band radar detection.U.S. Army Orders Saab Barracuda Camouflage Solutions – Armyrecognition.

Top view of a segment from a "bar-link" bicycle chain. A bar-link chain, also called a block-and-bar chain or a block chain, is a mechanical drive chain. It is composed of side plates, where each plate straddles one end of a block and is connected to the block with a pin going through a hole at one end of the block. Bar-link chains are simple, and often heavier and less efficient when compared with modern roller chains due to the lack of rolling motion as the chain engages and disengages the sprockets.

Jordan Frampton, also known as Jordan 'The Fury' Frampton started his speedway career in 2003, completing his first full season in 2004 with the Swindon Sprockets in the Conference League. In 2005, Frampton signed for the Sittingbourne Crusaders, also in the Conference League, where he established himself as a heat leader. At the start of 2006, Swindon and Sittingbourne dropped out of the Conference League and Frampton was left without a club until Premier League club Mildenhall Fen Tigers signed him later that year. He also ended the season riding for Weymouth Wildcats in their Conference Trophy team.

The Fokker-Leimberger used a rotary split-breech design known as the "nutcracker". In this design a temporary chamber is formed by joining the two cavities of touching, counter-rotating sprockets. The simplicity of the design was appealing, particularly because it contained no major parts using a reciprocating motion, like the breechblock used in many other automatic weapons. Ignoring the various material stresses, the maximum rate of fire was thus theoretically limited only by the time needed to complete the burning of the propellant from each cartridge (although, practically, barrel heating is a far more serious constraint).

While this is convenient for the user and does prevent torn film sprockets at the end of a roll, setting the counter up properly at the beginning of a roll is complex, awkward, and time-consuming. This is a typical example of much of Retina engineering - complex and ingenious, but perhaps over-engineered. The non-coupled selenium cell exposure meter reads out in exposure values (EVs) only. The camera is then set to the proper EV setting via an easily reached aperture release tab, though the EV scale itself is rather inconveniently located on the underside of the lens assembly.

Cyclists In Thames, New Zealand, around 1895 By the late 1880s, the safety bicycle was being produced: with a lower frame and pneumatic tyres, it was a popular model for women to ride, and consequently brought about a new form of freedom for them. Kate Sheppard was involved with the first cycle club in Christchurch in 1892: the Atalanta Cycle Club. The bicycle has therefore been credited as significant in bringing women's enfranchisement to New Zealand. It was the 'safety bicycle', with its chain, sprockets and similar sized wheels that catapulted the bicycle into the public arena.

Other changes included increased maximum pressurization to differential and changes to the cockpit layout. The Model 200C gave way to the Model B200C the same year, with the first Model B200T and Model B200CT being modified from a B200 and B200C respectively, the following year. Commencing in 1984 the B200, B200C and their derivatives were fitted with a revised landing gear retraction mechanism, actuated by hydraulic rams powered by an electric pump installed in the LH wing. This replaced the earlier electro-mechanical retraction system of gearboxes, driveshafts and chains and sprockets that was a throwback to the Twin Bonanza.

Power came from a large 5.0 L (5027 cc/306 in³) straight-4 engine with 3 valves per cylinder and a single overhead camshaft. This large engine had a 100 mm bore and very long 160 mm stroke, so it could only rev to about 2400 rpm. Power was transferred through a multi-plate metal-on-metal clutch to a 4-speed with reverse manual transmission. Two chains - one exposed each side outside of the main chassis rails - drove the rear wheels, with the factory providing three sets of rear wheel chain sprockets, which meant the maximum speed was close to 100mph.

A cube and its greebled version Greeble effects on a Lego spaceship model A greeble () or nurnie is a prominent detailing added to the surface of a larger object that makes it appear more complex, and therefore more visually interesting. It usually gives the audience an impression of increased scale. The detail can be made from simple geometric primitives (such as cylinders, cubes, and rectangles), or more complex shapes, such as pieces of machinery (cables, tanks, sprockets). Greebles are often present on models or drawings of fictional spacecraft or architectural constructs in science fiction and are used in the movie industry (special effects).

The definition was clearly written with gasoline-powered pedalcycles in mind. The requirement of an automatic transmission is troublesome for those who just want to add an electric-assist motor to a bicycle, for almost all bicycles have transmissions consisting of chains and manually shifted sprockets. The registration form asks for a VIN, making it difficult to register some foreign-made ebikes. The fine for riding an unregistered electric bike is approximately $160.00 per event as of 2007. On February 4, 2014, SB997 was introduced by Senator Matt Smith, which seeks to amend PA Vehicle Code to include "Pedalcycle with Electric Assist".

A velomobile's fairing shields the drivetrain from weather, as well as the rider. Drivetrain maintenance is often reduced compared to other cycles, especially unfaired bicycles, where the front wheel kicks up grit- containing dust, mud, and dirty water that lands directly on the chain and increases the rate of abrasive wear on the drivetrain—including chain and sprockets, but sometimes also derailleurs. The fairing of a velomobile tends to limit both the amount and the kinds of grit landing on the drivetrain. Some cycles use tooth-belt drive, which is less affected by grit, is quieter than a chain, and may be lighter.

The gearbox is different, with five forward and one reverse gear, instead of seven forward and one reverse. Suspension reverts from pneumatic to torsion bar, with six forged steel-aluminium rubber-tyred road wheels on each side, with the tracks driven by rear sprockets. The glacis is of laminate armour and the turret is armoured steel, with cavities in the turret cheeks containing either a ceramic filling or non-explosive reactive armor elements. The turret houses the same 125 mm 2A46 smoothbore gun as the T-72, which can fire anti-tank guided missiles as well as regular ordnance.

An encyclopedic overview can be found in Chapter 9 of "Bicycling Science" which covers both theory and experimental results. Some details extracted from these and other experiments are provided in the next subsection, with references to the original reports. Factors which have been shown to affect the drive-train efficiency include the type of transmission system (chain, shaft, belt), the type of gearing system (fixed, derailleur, hub, infinitely variable), the size of the sprockets used, the magnitude of the input power, the pedalling speed, and how rusty the chain is. For a particular gearing system, different gear ratios generally have different efficiencies.

Campagnolo Super Record rear derailleur (1983) Shimano XT rear derailleur on a mountain bike Pulley wheels for a rear derailleur The rear derailleur serves double duty: moving the chain between rear sprockets and taking up chain slack caused by moving to a smaller sprocket at the rear or a smaller chainring by the front derailleur. In order to accomplish this second task, it is positioned in the path of the bottom, slack portion of chain. Sometimes the rear-derailleurs are re-purposed as chain tensioners for single-speed bicycles that cannot adjust chain tension by a different method.

Although a typical plot might easily require a few thousand paper motions, back and forth, the paper doesn't slip. In a tiny roll-fed plotter made by Alps in Japan, teeth on thin sprockets indented the paper near its edges on the first pass and maintained registration on subsequent passes. Some Hewlett- Packard pen plotters had two-axis pen carriers and stationery paper (plot size was limited). However, the moving-paper H-P plotters had grit wheels (akin to machine-shop grinding wheels) which, on the first pass, indented the paper surface, and collectively maintained registration.

Originally called the Pantoptikon (also spelled 'Panoptikon'), it is perhaps the first widescreen film format, with an aspect ratio of 1.85. It had a film gauge of 51 mm and an aperture of 37 mm by 20 mm. It was instrumental in the history of film in that it created what became known as the "Latham loop", which are two loops of film, one on each side of the intermittent movement, which act as a buffer between continuously moving sprockets and the jerky motion of the intermittent movement. This relieved strain on the filmstrip and so enabled the shooting and projection of much longer motion pictures than had previously been possible.

The Loyd Carrier was built upon the mechanicals (engine, gearbox and transmission) of a 15 cwt 4x2 Fordson 7V truck with mild steel bodywork to which armour plate - 'BP Plate' (from "Bullet Proof") - was bolted (to the front and upper sides) depending on application. The engine was at the rear of the Carrier with the radiator behind rather than in front. The transmission then took the drive forward to the axle at the very front where it drove the tracks. Both the front drive sprockets and idlers (which were also sprocketed) at the rear of the tracks were fitted with brakes, actuated by a pair of levers by the driver.

This is similar to the claw mechanism in a motion picture camera. In 35 mm and 70 mm projectors, there usually is a special sprocket immediately underneath the pressure plate, known as the intermittent sprocket. Unlike all the other sprockets in the projector, which run continuously, the intermittent sprocket operates in tandem with the shutter, and only moves while the shutter is blocking the lamp, so that the motion of the film cannot be seen. It also moves in a discrete amount at a time, equal to the number of perforations that make up a frame (4 for 35 mm, 5 for 70 mm).

When driving in a straight line the two engines were locked; turning the steering wheel gradually closed the throttle for the engine of one track and opened the throttle for the engine driving the other. The two engines were joined at their cross-shafts, from which the final drive to the tracks was by chains to sprockets on either side. When steering the clutches joining the cross-shafts were released, one engine sped up while the other slowed down, the turn being on the side opposite to that of the faster running engine. The steering effect could be increased by use of the brakes on one engine or another.

Some line printers had covers that opened automatically when the printer required attention. Standard "green bar" page sizes included portrait-format pages of 8½ × 11 inches, usually printed at 80 columns by 66 lines of characters (at 6 lines per inch) or 88 lines (at 8 LPI), and landscape-format pages of 14 × 11 inches, usually printed at 132 columns by 66 or 88 lines. Also common were landscape-format pages of 14 × 8½ inches, allowing for 132 columns by 66 lines (at 8 LPI) on a more compact page. These continuous forms were advanced through the printer by means of tractors (sprockets or sprocket belts).

A case where numerous idler gears might be used is as described above, where there are a number of output gears that need to be driven simultaneously. Caterpillar track idler wheels A tracked vehicle uses a combination of wheels and rollers, including drive sprockets, idler wheels, track return rollers and road wheels. It is quite similar in concept to a conveyor belt, only instead of a machine carrying objects on top of a powered continuous belt, it's a machine that moves itself over a continuous belt. In a typical application, power is transmitted to a drive sprocket (or drive wheel), which drives the track around its loop.

Most conventional bicycle wheels now use 32 or 36 spokes front and rear, although the asymmetry of the rear wheel (to allow for the cluster of sprockets), and the additional weight it carries, means it benefits from having more spokes than the front. Commonly used models vary from 18 spokes for racing bikes to 36 for cross-country touring bikes to 48 spokes on tandems and heavily abused BMX bikes. The minimum number of spokes allowed for competition is 12.UCI Competition Rules - Some lowrider bicycles use as many as 144 brightly chromed spokes per wheel, although these are not meant for serious riding.

History of the Tour de France: 1920–1939 - Les Forcats de la Route by Mitch Mueller Derailleurs did not become common road racing equipment until 1938 when Simplex introduced a cable-shifted derailleur. In 1949 Campagnolo introduced the Gran Sport, a more refined version of the then already existing, yet less commercially successful, cable-operated parallelogram rear derailleurs. In 1964, Suntour invented the slant-parallelogram rear derailleur, which let the jockey pulley maintain a more constant distance from the different sized sprockets, resulting in easier shifting. Once the patents expired, other manufacturers adopted this design, at least for their better models, and the "slant parallelogram" remains the current rear derailleur pattern.

The Central Utah Project was active in the area for 20 years and provided good jobs from 1967 to 1987. A recent expansion to the water treatment plant northwest of town will start supplying culinary water to the community of Roosevelt some away. Duchesne is home to a number of heavy machine and steel manufacturers. A wide variety of products and parts are manufactured, including underground cranes, shield haulers, rifle barrels, steam locomotive parts, drill collars, turbine parts, gears, sprockets, and splines for the oil fields, steel mills, coal mines, trona mines, power plants, other machine shops, manufacturers and other industries in many capacities.

A hob — the cutter used for hobbing. Hobbing is a machining process for gear cutting, cutting splines, and cutting sprockets on a hobbing machine, which is a special type of milling machine. The teeth or splines of the gear are progressively cut into the material (a flat, cylindrical piece of metal) by a series of cuts made by a cutting tool called a hob. Compared to other gear forming processes it is relatively inexpensive but still quite accurate, thus it is used for a broad range of parts and quantities.. It is the most widely used gear cutting process for creating spur and helical gears.

Formula LGB is a series of single seater, open wheel class race cars manufactured by Super Speeds (A division of L.G.Balakrishnan Brothers, the manufacturers of Rolon Chains and Sprockets) for LG Sports in Coimbatore, India. These cars are similar to the wingless Formula Fords intended as a low cost starter series with power in the range of 90 to 100 bhp (70 to 75 kW). The cars were launched in India in 2003 and up till 2005 only one model was manufactured hence simply known as Formula LGB.In 2006 when another Hyundai engined model was launched the existing Formula LGB became Formula LGB Swift to avoid confusion of model name.

To turn the vehicle to the left, the brakes were applied on that side and the Carrier would slew round the stopped track. The upper hull covered the front and sides but was open to the rear and above; as the Carrier was not expected to function as a fighting vehicle, this was not an issue. To protect the occupants from the weather, a canvas tilt could be put up; this was standard fitment from the factory. PartsBook As part of the rapid development program, the Loyd used parts from other vehicles: From the Universal Carrier, the track, drive sprockets, and Horstmann suspension units; from the Fordson 7V, the chassis, engine, gearbox, torque tube and front axle.

In the second series, billed in some cases as Motormouth II or Motormouth 2, there were changes, including the introduction of new graphics and set elements based on cogs and sprockets. The use of the giant mouth declined following this alteration. The show's third series - which boasted new graphics and remixed theme music, and was for a brief time billed as All New Motormouth - also had a new, predominantly white set; the giant mouth was removed altogether at this point, along with all other remaining inflatables. This series saw the introduction of a diner-style set (sometimes referred to as 'The Motormouth Cafe') which saw guests and audience members sitting at tables.

Initial development efforts were conducted for Sony's Columbia Pictures Sound Department under contract with Semetex Corp. of Torrance, California, U.S.A.. At Semetex, the SDDS Chief Architect was Jaye Waas and the Chief Optical Engineer was Mark Waring. The Semetex prototype design actually had the eight channels of uncompressed data placed into three locations: data bordering both sides of the analog sound track and additional data tracks bordering the opposite edge of the picture frame. These locations were chosen to ensure the data were not placed into the sprocket perforation area of the film to prevent the known wear and degradation that occurs in the perforation area (due to the mechanical film sprockets) from degrading the data.

Clocking and guide tracks were placed on each side of the film near the sprockets. The prototype sound camera imprinted the Digital audio and Analog audio 'at speed'. A companion digital reader was designed to form a complete system. After Sony received the prototype they enlarged the data bits from the original 8 micron (micrometer) size and moved the data locations; the eight digital audio channels are now recorded on (and recovered from) the edges of the film. As Sony engineers became more actively involved in the project, the design of the SDDS format evolved toward a more robust implementation, including the use of 5:1 ATRAC data compression, extensive error detection and correction, and most critically redundancy.

Additionally, the loss of a single segment in a track immobilizes the entire vehicle, which can be a disadvantage in situations where high reliability is important. Tracks can also ride off their guide wheels, idlers or sprockets, which can cause them to jam or to come completely off the guide system (this is called a 'thrown' track). Jammed tracks may become so tight that the track may need to be broken before a repair is possible, which requires either explosives or special tools. Multi- wheeled vehicles, for example, 8 X 8 military vehicles, may often continue driving even after the loss of one or more non-sequential wheels, depending on the base wheel pattern and drive train.

Schachtellaufwerk interleaved wheels on a Panther The suspension consisted of front drive sprockets, rear idlers and eight double-interleaved rubber-rimmed steel road wheels on each side – in the so-called Schachtellaufwerk design, suspended on a dual torsion bar suspension. The dual torsion bar system, designed by Professor Ernst Lehr, allowed for a wide travel stroke and rapid oscillations with high reliability, thus allowing for relatively high speed travel over undulating terrain. The extra space required for the bars running across the length of the bottom of the hull, below the turret basket, increased the overall height of the tank. When damaged by mines, the torsion bars often required a welding torch for removal.Spielberger 1993, pp.

A freewheel and freewheel hub A freehub (above) for use with a cassette and a threaded hub (below) for use with a freewheel A freewheel (also known as a block) consists of either a single sprocket or a set of sprockets mounted on a body which contains an internal ratcheting mechanism and mounts on a threaded hub. Threaded rear hubs were available in different thread patterns depending on the country of manufacture, French and British threads being the most common. British C.E.I. (Cycle Engineers Institute) thread was adopted as the international standard and is now known as B.S.C. (British Standard Cycle). It is a standardized right-hand thread (1.375 x 24 TPI) onto which a standard freewheel is screwed.

An eight-speed cassette is wider at 41.5 mm than a second generation Shimano seven. This results in functionally compatible shifters, but specific freehub bodies, or necessitating the use of a spacer with a seven-speed cassette on an eight-speed hub. Eight- and nine- speed cassettes and freehub bodies have the same width (41.5 mm), yet the sprockets on the nine-speed are closer together; as a result the shifters are not compatible, but they use the same freehub bodies. Ten-speed cassettes are slightly more narrow than eight/nine so they fit on those freehubs but need a spacer, conversely eight/nine-speed cassettes do not fit on ten-speed freehubs.

In 1968, the C2SS could be converted into a C2TR trail machine by easily installing the Trail Kit that was supplied by the manufacturer as optional parts. In 1968 the C2SS was renamed the C2TR apparently indicating an off-road capability. It had a new style fuel tank design without rubber knee grips, a contrasting "Kawasaki" decal covering the entire side of the tank, a raised front fender, a rear rack for small amounts of cargo, and 4-speed transmission with high and low gearing via 2 rear sprockets changed manually. In 1969 the C2TR had 8 speeds (4 actual speeds) through a unique high/low range gearing switch rather than a rear sprocket change.

Since the development of the sport of mountain biking in the 1970s, many new subtypes of mountain biking have developed, such as cross-country (XC), enduro/all mountain, freeride, downhill, and a variety of track and slalom types. Each of these place different demands on the bike, requiring different designs for optimal performance. MTB development has led to an increase in suspension travel, now often up to , and gearing up to 27 speeds, to facilitate both climbing and rapid descents. Advances in gearing have also led to a "1x" (pronounced "one-by") trend, simplifying the gearing to one chainring in the front and a cassette at the rear, typically with 9 to 12 sprockets.

This style is commonly found on racing bicycles with two chainrings. The relative step on the chainrings (say 35%) is typically around three or four times the relative step on the cogset (say 8% or 10%), e.g. chainrings 39-53 and close-range cogsets 12-13-14-15-16-17-19-21 or 12-13-15-17-19-21-23-25. This arrangement provides much more scope for adjusting the gear ratio to maintain a constant pedalling speed, but any change of chainring must be accompanied by a simultaneous change of 3 or 4 sprockets on the cogset if the goal is to switch to the next higher or lower gear ratio.

Reliability and controllability are the advantages of chain-driven weapons over their recoil-actuated counterparts. Recoil-actuated firearms depend upon the sometimes unreliable firing of a cartridge to power the cycle of action, whereas a chain gun uses an electric motor to drive a chain which moves in a rectangular circuit via four sprockets that apply tension to it. One link of the chain is connected to the bolt assembly, moving it back and forth to load, fire, extract, and eject cartridges. A misfired round does not stop the functioning of the weapon, as it might with guns that use energy from a fired cartridge to load the next round; it is simply ejected.

|
There are also a small number of hubs with a splined section machined onto the side of the hub where a sprocket can be attached with no freewheel mechanism. 135 mm spaced trials hubs originally were taken from mountain bikes, but modern designs are focused on making room for as many sprockets as possible and often don't have the torque carrying capacity needed to be safe for trials use. Many of them also don't pick up drive quickly enough to give a trials rider the instant pedal response required for precision riding. For comparison some mountain bike hubs have as few as 16 clicks per revolution, or one click every 22.5 degrees rotation.

The chains were replaced as part of a valve and piston examination at around , by which time they were considerably worn. This wear, in the chain pins and sprockets, could result in an elongation of the chains by as much as . Bulleid asserted that a slack of would be absorbed by the chain coming under load, with the remaining valve irregularity corrected by adjusting the cut-off. Chain-stretch is widely considered to be the cause of the gear's inefficiencies, but another cause may have been geometrical due to the sequential proportions of levers, especially the multiplying rockers that transmitted the limited movement of the "miniaturised" valve gear to the union link driving the long travel piston valve.

If a similar system were installed on all rowing ergometers used in indoor rowing competitions, consistency between machines would be guaranteed because the variability factor of elastic cord resistance would be eliminated, and this would therefore ensure that the monitor displayed actual user energy input. In a 1988 US patent (US 4772013A), Elliot Tarlow discloses another non-elastic chain/cable take-up and handle return strategy. Described and depicted is a continuous chain/cable loop that passes around the flywheel sprocket and around and between fixed pulleys and sprockets positioned fore and aft on the device. The handle is secured in the middle of the exposed upper horizontal section of the chain/cable loop.

From June 1, 1925, the cooling system was improved on all models by a fan ( previously fitted only to the Cabriolet ). There was a single Solex carburetor The ignition initially by battery, coil and distributor was replaced around March 1923 by a magneto ignition. The gearbox had three unsynchronized ratios plus a reverse gear; the straight-sized sprocket tended to "sing" especially in 1st and 2nd gear ( not in 3rd, direct drive ), and became noisy when the gears were worn or when the bush between the primary and secondary shaft was loose. This excessive play caused the primary train to become misaligned from the second train, causing the sprockets to operate on the end of the teeth, hence additional noise and premature wear.

Overfilling can lead to leaks, as can laying the hub/cycle on its side in some low-pressure aircraft holds. The sprocket on the hub is made for standard-pitch derailleur-type bicycle chains 1/2″ × 3/32″ (ISO 082) and is offered with different numbers of teeth, like 13/15/16/17. The 15-, 16-, and 17-tooth sprockets are reversible, offering double sprocket life once the sprocket is worn out in one direction. The 13-tooth sprocket is non-reversible and has a 4 mm outward offset, changing the chain-line from 54 to 58 mm, this because the smaller sprocket makes the chain run closer to the axle, and the chain would rub the hub shell if the sprocket were not offset.

A Shimano Deore right crankset, showing crank arm, spider, three chainrings and chainring guard Belt-drive crankset on a Trek District A chainring that incorporates the manufacturer's brand name The crankset (in the US) or chainset (in the UK), is the component of a bicycle drivetrain that converts the reciprocating motion of the rider's legs into rotational motion used to drive the chain or belt, which in turn drives the rear wheel. It consists of one or more sprockets, also called chainrings or chainwheels attached to the cranks, arms, or crankarms to which the pedals attach. It is connected to the rider by the pedals, to the bicycle frame by the bottom bracket, and to the rear sprocket, cassette or freewheel via the chain.

The aircraft selection is limited to the North Korean attack helicopter and a fictional American VTOL (each of which can transport six passengers and two crew). Crytek also included an amphibious armored personnel carrier, its wheeled version that can travel on water and land, although this vehicle was only available for those who pre-ordered the game. Damage modeling, although limited in vehicles, is most noticeable in the ability to burst tires, although wheeled vehicles can still move even if all the tires are gone, slowly rolling along on the rims. Tracked vehicles such as tanks or APCs can lose their tracks as a result of damage, but may continue moving even though there is no way for the drive sprockets to propel the vehicle.

In the earliest models, power from the engine (which was mounted in front, started by rope, and operated with a hand throttle) was transferred by a long drive belt to a simple lever-operated forward/reverse transmission between the rear wheels. This transmission was under the bench seat, and drove power to serrated, cast iron "gears" which drove the wheels through contact friction atop the 2.25x10 semi-pneumatic tire treads. Braking action was accomplished by reversing the transmission. This unsatisfactory system resulted in heavy tire wear and was soon replaced by a drive belt from an engine-mounted centrifugal clutch to a jackshaft under the seat, and from there by forward-only chain drive to sprockets on one or both rear wheels.

In a similar way, manually changing the sprockets on a motorcycle can change the characteristics of acceleration and top speed by modifying the final drive gear ratio. The final drive gear ratio can be calculated by dividing the number of teeth on the rear sprocket by the number of teeth on the counter- shaft sprocket. With respect to the stock gearing on a motorcycle, installing a smaller counter-shaft sprocket (fewer teeth), or a larger rear sprocket (more teeth), produces a lower gear ratio, which increases the acceleration of the motorcycle but decreases its top speed. Installing a larger counter-shaft sprocket, or a smaller rear sprocket, produces a higher gear ratio, which decreases the acceleration of the motorcycle but increases its top speed.

The co- founder of Apple, Steve Jobs, disliked video games, but Apple has at times attempted to market the platform for gaming. In 1996, the company released a series of game-enabling APIs called Game Sprockets. In April 1999, Jobs gave an interview with the UK-based Arcade magazine to promote the PowerPC G3-based computers Apple were selling with then new ATI Rage 128 graphics cards, and describing how Apple was "trying to build the best gaming platform in the world so developers are attracted to write for it" and "trying to leapfrog the PC industry". A 2007 interview with Valve's Gabe Newell included the question of why his company was keeping their games and gaming technology "a strictly Windows project".

When running the printer, it generally prints one line of text at a time. The printer head is attached to a metal bar that ensures correct alignment, but horizontal positioning is controlled by a band that attaches to sprockets on two wheels at each side which is then driven with an electric motor. This band may be made of stainless steel, phosphor bronze or beryllium copper alloys, nylon or various synthetic materials with a twisted nylon core to prevent stretching. Actual position can be found out either by dead count using a stepper motor, rotary encoder attached to one wheel or a transparent plastic band with markings that is read by an optical sensor on the printer head (common on inkjets).

This term has no generally accepted meaning. Originally it referred to a gearing arrangement which had one especially low gear (for climbing Alpine passes); this low gear often had a larger than average jump to the next lowest gear. In the 1960s the term was used by salespeople to refer to then current 10-speed bicycles (2 chainrings, 5-sprocket cogset), without any regard to its original meaning. The nearest current equivalent to the original meaning can be found in the Shimano Megarange cogsets, where most of the sprockets have roughly a 15% relative difference, except for the largest sprocket which has roughly a 30% difference; this provides a much lower gear than normal at the cost of a large gearing jump.

The preserved American-captured Elefant, showing the suspension it shared with the VK 4501 (P) chassis. The two Porsche air-cooled engines in each vehicle were replaced by two 300 PS (296 hp; 221 kW) Maybach HL120 TRM engines. The engines drove a single Siemens-Schuckert 500 kVA generator each, which powered two Siemens 230 kW (312.7 PS) individual-output electric motors, one each connected to each of the rear sprockets. The electric motors also acted as the vehicle's steering unit. This "petrol-electrical" drive delivered 0.11 km/l (909 litres/100 km or 0.26 MPG) off-road and 0.15 km/l (667 litres/100 km or 0.35 MPG) on road at a maximum speed of 10 km/h off-road and 30 km/h on road.

Flat belt on a belt pulley Belt and pulley system Cone pulley driven from above by a line shaft A belt and pulley system is characterized by two or more pulleys in common to a belt. This allows for mechanical power, torque, and speed to be transmitted across axles. If the pulleys are of differing diameters, a mechanical advantage is realized. A belt drive is analogous to that of a chain drive; however, a belt sheave may be smooth (devoid of discrete interlocking members as would be found on a chain sprocket, spur gear, or timing belt) so that the mechanical advantage is approximately given by the ratio of the pitch diameter of the sheaves only, not fixed exactly by the ratio of teeth as with gears and sprockets.

Final drives are mounted in the front and the idler sprockets with track tensioners are mounted at the rear. The running gear has six road wheel stations per side, which guide a lightweight steel or segmented rubber band- type track. The rubber-tyred road wheels are mounted on a suspension system comprising swing arms with conventional torsion bars and a SupaShock damper systems, this set-up is proven to be reliable and cost-efficient. The Lynx is fitted with as many mature sub-systems as possible in order to facilitate maintenance. The KF41 transmission is the same as that used in the Puma and Ajax vehicles, the Liebherr engine is widely used in the construction industry, and the driver’s station is taken from the Kodiak armoured engineering vehicle.

Other parts for this tank were also manufactured by several Romanian factories: drive sprockets were produced at the Reșița Works, the fore-mentioned metal-rimmed road wheels along with new tracks were produced at the Concordia Works in Ploiești, and cylinder heads along with drive shafts were cast at the Basarab Works in Bucharest and finished by IAR at Brașov. For the future rearming of 30 R35s as tank destroyers, new gun mounts containing recoil mechanisms were cast at the Concordia Works and fitted as extension to the R35's turret. Romania's T-60 light tanks, captured from the Soviet Union, were to be rebuilt as tank destroyers. To support the added weight this would entail, new road wheels and stronger torsion bars were cast and finished by the Industria Sirmei at Turda, IAR at Brașov and Concordia at Ploiești.

KH50 Vollmer subsequently moved to Czechoslovakia, to join the Skoda company for whom he designed a wheel/track light tank, the KH-50 (Kolo-Housenka). This design had roadwheels mounted on the drive sprockets and jockey wheels behind them to support the tracks. Despite impressive specifications for the period - 13 mm armour, 37 mm turret- mounted armament, and a 50 hp engine capable of driving the tank at (on tracks) and (on wheels) - it was rejected by the Czech army. The army was, however, impressed by the hybrid wheel/track concept and commissioned further studies, which resulted in the KH-60 (1928–29) and the KH-70 (1930). In these two designs the engine power was increased to 60 hp and 70 hp respectively and a better system was developed for switching between track and wheel use which allowed a change in less than 10 minutes.

The machine gun feeds from the left-hand side through a variety of disintegrating metallic link ammunition belt types: the American M13 linked belt, the German DM6 counterpart to the M13 or the German non-disintegrating metallic link DM1 belt. The ratcheting wheel feed unit was designed as an easily removable module that is inserted into the bottom portion of the feed block (installed in place of the standard magazine well), below the barrel axis. As a result of this configuration (the bolt passes over the belt), the ammunition belt is aligned upside down compared to most other belt-fed weapons (that is, the links face downward). The feed mechanism is actuated by the reciprocating movement of the bolt; a curved cam slot on the bottom of the bolt engages an actuator in the feed mechanism, rotating the double sprockets and positioning a new round in the feed path.

After World War I, the Polish army began designing tankettes, light tanks, and armored vehicles, many by Škoda. The German engineer Joseph Vollmer joined Škoda and designed a wheel/track light tank, the KH-50 (Kolo-Housenka). This design had roadwheels mounted on the drive sprockets and jockey wheels behind them to support the tracks. During World War I, Vollmer was chief designer for the German War Department's motor vehicle section, and he had designed the World War I German tanks A7V, K-Wagen, LK I and LK II. Despite the design for the KH-50 (Kolo-Housenka) having impressive specifications for the period - 13 mm armour, 37 mm turret-mounted armament, and a 50 hp engine capable of driving the tank at 8 miles per hour (13 km/h) (on tracks) and 22 miles per hour (35 km/h) (on wheels) - it was rejected by the Czech army.

Choices of equipment tend more towards the idiosyncratic than in road racing; for example single-speed bicycles also have some popularity due to the advantage of mechanical simplicity in the often very muddy conditions and the fringe nature of the sport. Gearing is typically lower, with most common setups using a 46-36 (110mm BCD) or 48-38 (130mm BCD) chainring combination with a 12-25 to 12-30 cassette. Some riders opt to use a single chainring in the front (typically a 40-42 tooth chainring) while retaining multiple sprockets in the rear cassette. This has some of the advantages of the single-speed: the weight of the front derailleur and the front shift lever are lost, a single chainring allows for a tighter chainline, thus reducing the chance of throwing a chain on a bumpy course, and further, racing is psychologically simpler.

The drive train was also revised, with the road wheels no longer powered so the tank could not be driven on its wheels alone. Better tracks were used, with rear-mounted drive sprockets and in trials, over was attained on them but later the speed was governed to . The armour of the A13E2 was , in line with other pre-war fast tank designs. The A13E3 was the final trials model, which led to the production tank, A13 MkI, Cruiser Tank Mk III, which entered production in 1939 at Nuffield Mechanization & Aero Limited, a munitions subsidiary of Morris Motors. An order for 65 tanks was placed and at least 30 tanks completed when the War Office decided to build a new model with thicker armour. The A13 MkII, Cruiser Tank Mk IV, had a maximum armour thickness of and faceted armour was mounted on the original turret sides and rear.

Side-rear angle view of Type 5 Chi-Ri captured, post-surrender The Type 5 Chi-Ri featured a lengthened version of the Type 4 Chi-To chassis, with eight road wheels per side instead of the seven of the Chi-To. It had the usual Japanese track arrangement with forward mounted drive sprockets and rear mounted idlers. The Type 5 Chi-Ri had sloped welded armor, with a maximum thickness of 75 mm at the front hull; 25–50 mm on the side; 50 mm on the rear and 50 mm on the turret.History of War: Type 5 Chi-Ri Medium Tank The Type 5 Chi-Ri was initially to be powered by a Mitsubishi Diesel engine, but the advancements needed to provide the necessary horsepower fell behind schedule, and an 800 hp V-12 gasoline-fueled aircraft engine designed by BMW in Germany and licensed to Kawasaki Heavy Industries in Japan was selected instead.

The vehicle's transmission was a friction drive, consisting of a flat spinning flywheel mounted on the engine which was set at right angles to a rubber lined steel drive wheel which slid from side to side on a drive shaft mounted in parallel to the rear axle. Sprockets on the end of the drive shaft relayed power to the rear wheels via a pair of chains, one per wheel. The friction drive was prone to slippage due to environmental conditions (water) and if the rubber drive wheel was allowed to rest against the spinning flywheel for a long period of time it would develop a flat spot which would produce an uneven power transfer. The transmission was infinitely variable, however, allowing the user to simply progressively slide the rubber covered wheel from a neutral position at the center of the flywheel to a position closer to the edge of the flywheel to vary the gear ratio.

Bushing, 5. Roller If the chain is not being used for a high wear application (for instance if it is just transmitting motion from a hand- operated lever to a control shaft on a machine, or a sliding door on an oven), then one of the simpler types of chain may still be used. Conversely, where extra strength but the smooth drive of a smaller pitch is required, the chain may be "siamesed"; instead of just two rows of plates on the outer sides of the chain, there may be three ("duplex"), four ("triplex"), or more rows of plates running parallel, with bushings and rollers between each adjacent pair, and the same number of rows of teeth running in parallel on the sprockets to match. Timing chains on automotive engines, for example, typically have multiple rows of plates called strands. Roller chain is made in several sizes, the most common American National Standards Institute (ANSI) standards being 40, 50, 60, and 80.

Columbia Bicycles advertisement from 1886 Bicycle manufacturing proved to be a training ground for other industries and led to the development of advanced metalworking techniques, both for the frames themselves and for special components such as ball bearings, washers, and sprockets. These techniques later enabled skilled metalworkers and mechanics to develop the components used in early automobiles and aircraft. Wilbur and Orville Wright, a pair of businessmen, ran the Wright Cycle Company which designed, manufactured and sold their bicycles during the bike boom of the 1890s. They also served to teach the industrial models later adopted, including mechanization and mass production (later copied and adopted by Ford and General Motors), vertical integration (also later copied and adopted by Ford), aggressive advertising (as much as 10% of all advertising in U.S. periodicals in 1898 was by bicycle makers), lobbying for better roads (which had the side benefit of acting as advertising, and of improving sales by providing more places to ride), all first practiced by Pope.

At 0700 the 37th jumped off from Bercheaux and swiftly took Bauxles-Rosieres, Nives and Remoiville. At dawn on 26 December 1944, the 37th struck again, taking Remichampagne, and then seizing the high ground near Chochiment, only three miles from Bastogne. Announcing the plan to relieve the surrounded 101st Airborne Division, LTC Abrams, commanding the 37th, made the undramatic statement, "We're going in to those people now." The lead vehicle in that attack was a Sherman tank nicknamed "Cobra King""'Cobra King' led 4th Armored Division column during Battle of the Bulge", 25 February 2009 Retrieved 9 October 2014 and commanded by 1st Lt. Charles Boggess Jr., of Greenville, Illinois. Boggess was the commanding officer of Company C, 37th Tank Battalion. There were but eight other tanks in Company C when the "move out" order came, but at 1515 hours all nine sets of sprockets turned, leading the 37th northward to the embattled 101st Airborne Division.

Casler, Dickson, and Marvyn had worked together in 1893 on a detective camera the size of a watch called the Photoret. Dickson, who at the time was working for Thomas Edison, next proposed that they work on a peephole film viewing device superior to Edison's Kinetoscope machine. Casler, following Dickson's proposal, invented the "Mutoscope", which displayed short films through flip- cards rotated by a hand crank that could be slowed at the operator's will, unlike Edison's motorized Kinetoscope, in which films were viewed through actual 35 mm film. The prototype of the "Mutograph" camera was completed in November 1894, first tested with film in June 1895, and the first official Mutoscope films were made in August 1895. To avoire infringement on Edison's motion photo patents, the Mutograph camera used continuous movement friction rollers to move 68 mm film into the camera, instead of intermittent movement by sprockets as Edison's 35 mm camera did.

The front sprockets are spoked, with solid rear idlers - the reverse of the Light Dragon Marks I and II. For identification purposes the Light Dragon Mark III has the rear sprocket set high, and the suspension springs form a triangle shape - in contrast with the Light Tank Mk IV, which has the rear sprocket on the ground and suspension springs both pointing the same way. The sloping front was re-designed with a flat vertical section immediately in front of the driver: the headlights are mounted on boxy extensions at driver level. Distinctive forward-sloping mudguard wings cover the tracks at the front of the vehicle, in common with the Machine Gun Carrier Mk I. The engine, gearbox and transmission were all made by Ford: the centrally-located engine was a commercial V-8, coupled to a 4-speed gearbox with 1 reverse, driving a standard truck rear axle and differential. The steering, probably the invention of Sir John Carden and his assistant Leslie Little, was a great improvement on the earlier Dragons.

In this sense, the scale was revolutionary: it evolved into the more-commonly encountered form consisting of two pans placed on vertical column located above the fulcrum and the parallelogram below them. The advantage of the Roberval design is that no matter where equal weights are placed in the pans, the scale will still balance. A gear balance:A rare document on "gear balance". A = Axle, F = Frame, G = Generator, GL = geared linkage, WL = weighted lever; counter weight added for balance, all the gear linkages free running on the rotating frameFurther developments have included a "gear balance" in which the parallelogram is replaced by any odd number of interlocking gears greater than one, with alternating gears of the same size and with the central gear fixed to a stand and the outside gears fixed to pans, as well as the "sprocket gear balance" consisting of a bicycle-type chain looped around an odd number of sprockets with the central one fixed and the outermost two free to pivot and attached to a pan.

Since the 1980s, mountain bikes have had anywhere from 7 to 27 speeds, with 1 to 3 chain-rings on the crankset and 4 to 12 sprockets in the cogset. 30-speed and 33-speed mountain bikes were found to be unworkable, as the mud-shedding capabilities of a 10-speed or 11-speed cassette, and the intricacies of a 10-speed or 11-speed rear derailleur were originally not found to be suitable combined with front shifters, although 10, 11 and 12 speed cassettes are now commonplace in single front chainring bicycles. However, many pro-level mountain bikers have taken to using a narrower 10-speed road chain with a 9-speed setup in an effort to reduce the weight of their bike. In early 2009, component group SRAM announced their release of their XX groupset, which uses a 2-speed front derailleur, and a 10-speed rear derailleur and cassette, similar to that of a road bike. Mud-shedding capabilities of their 10-speed XX cassette are made suitable for MTB use by extensive CNC machining of the cassette.

Sprockets with Vernier adjusters were fitted to allow for chain wear, and the cam timing was supposed to be checked every . Early cars also suffered from corrosion of the cylinder heads caused by using copper gaskets on aluminium heads; nevertheless, the car was quite lively for its day, considering the cubic capacity. When leaving the factory, Flavias originally fitted either Pirelli Cinturato 165HR14 tyres (CA67) or Pirelli Cinturato 155HR15 tyres (CA67). Flavia Series II sedan (819) Zagato-bodied Flavia sport Later development of the engine included an enlargement to 1.8 L, a mechanical injection version using the Kugelfischer system, and a five-speed manual gearbox. In May 1967 a rebodied version of the Berlina with a new interior went on sale, with model number 819, it is usually referred to as the Series II. The engines were originally the same as earlier (74 mm stroke in 1500, 1800, 1800 fuel injected), but in 1969 these were changed to a new generation with an 80 mm stroke, narrow-bore versions of the new 2-litre 820-series engine.

The gear ring dogs would ratchet around the clutch using the ramps and springs if the hub was trying to engage Normal and High gear at the same time, though allowing this to happen through slow shifting can cause excessive clutch wear and render the hub inoperable. In Low gear, this isn't a problem as the low gear pawls can be overrun by a higher gear, while Normal and High gears use the same pawls, requiring an alternative solution. The K hub spawned a Tricoaster version with back pedal brake, designated KC, in 1921 and both close ratio (KS), and medium ratio (KSW) variants in 1932 and 1933 respectively. With the introduction of 90mm drum brakes LBF/BF/BFC and LBR/BR/BRC in 1931, the first Sturmey-Archer 3-speed drum brake was introduced, the KB. The KB was joined in 1934 by the KT 111mm tandem drum brake, part of a family of 111mm drum brakes alongside the BFT and BRT front and rear drum brakes (BR type drum brakes are not gear hubs and are instead threaded for fixed sprockets or freewheels).

The View-Master Personal stereo camera uses 35mm film to produce 69 stereo pairs from a 36-exposure roll of film.View-Master Three Dimension Photography (camera instruction manual) page 19 This is accomplished by a "lens shift" mechanism which starts out in the "A" position to expose the bottom half of the film while the film is wound out of the canister and then in the "B" position the top half of the film is exposed while it is wound back into the canister. The A/B selector, aside from shifting the images up and down also adjusts the film winding mechanism so that when the selector is on "A" the knob turns counter clockwise and the film counter counts down, and when it is on "B" the knob turns clockwise and the counter counts up.View-Master Three Dimension Photography (camera instruction manual) pages 12–13 The View-Master Personal advances by 8 sprockets with each picture and, as with Realist format cameras, there are two unrelated images between the right and left images of a pair, but there are also two smaller blank spaces.
