This, combined with a primary concentrator of 1000:1 would result in a very high 10,000:1 ratio which permits a reasonable pointing accuracy requirement of 0.1°.

Because the ore contained relatively little copper, an ore concentrate was produced before shipment to an ore processing plant. This necessitated the construction of a concentrator, and both an inclined and aerial tramway system to transport crushed ore from the mine to the concentrator. In 1904, a gravity concentrator was installed at the site, capable of processing 200 tons of ore daily. The output was a concentrate of about 10% copper, which was sent to Crofton for smelting.

A flow schematic of process gas in the Fluidized Bed Concentrator system. Industrial Processes requiring ventilation, including paint booths, printing, and chemical production, exhaust the ventilated air to the fluidized bed concentrator (FBC) at room temperature. The air first passes into the Adsorption tower, where it moves through six perforated trays of clean carbon beads. The 0.7mm Bead activated carbon (BAC) fluidizes in the trays and captures the VOCs as they intermix.

Acceptance angle is the maximum angle at which incoming sunlight can be captured by a solar concentrator. Its value depends on the concentration of the optic and the refractive index in which the receiver is immersed. Maximizing the acceptance angle of a concentrator is desirable in practical systems and it may be achieved by using nonimaging optics. For concentrators that concentrate light in two dimensions, the acceptance angle may be different in the two directions.

Concentrator systems also often require reliable control systems to accurately track the sun and to protect the PV cells from damaging over-temperature conditions. However, there are also stationery PVT collector types that use nonimaging reflectors, such as the Compound Parabolic Concentrator (CPC), and do not have to track the sun. Under ideal conditions, about 75% of the sun's power directly incident upon such systems can be gathered as electricity and heat at temperatures up to 160°C. For more details, see the discussion of CPVT within the article for concentrated photovoltaics.

Depending on hardware used, concentrators support the following line types: analogue lines (either single or multiple line groups), ISDN2 (basic rate ISDN) & ISDN30 (primary rate ISDN). ISDN can run either UK-specific DASS2 or ETSI(euro) protocols. Subject to certain restrictions a concentrator can run any mix of line types, this allows operators to balance business ISDN users with residential users to give a better service to both and efficiency for the operator. Concentrator units can either stand alone as remote concentrators or be co-located with the exchange core (switch & processors).

Fortunately, fire crews managed to save the pelton wheel powered, hydro electric plant--a small one story structure that sat right beside No.2 Concentrator. (The mine generated half of its power needs, and the other half came from BC Electric which strung a power line to the mine up the Capilano Valley,) A temporary decline in copper prices provided the company with an incentive to upgrade the concentrator, and it hired San Francisco metallurgical engineering firm Bradley, Bruff, and Labarthe to design a new structure to house it.

The Data Concentrator, a special-purpose peripheral device for the attachment of interactive terminals to the System/360 Model 67, overview and photos from Dave Mills, the project leader and chief designer during its development The DC was developed as part of the CONCOMP project by Dave Mills and others and was the first non-IBM device developed for attachment to an IBM I/O Channel.The Data Concentrator, David L. Mills, CONCOMP Project, University of Michigan, 1968 Initially a PDP-8 based system, the DC was upgraded to use PDP-11 hardware and a Remote Data Concentrator (RDC) was developed that used LSI-11 hardware that connected back to a DC over a synchronous data circuit. The University of British Columbia (UBC) developed two PDP-11 based systems: the Host Interface Machine (HIM) and the Network Interface Machine (NIM). The University of Alberta used a PDP-11 based Front- end processor.

The success of a solvent extraction and electrowinning plant commissioned in 1979 ended vat leaching by the mid-1980s, and the concentrator closed in 1986 as well. The copper rod mill was commissioned in 1966.Miami mine at Freeport- McMoRan.

In 2016, Energa-Operator (based in Poland) installed 6.6k Data Concentrator Units with balancing meter functionality in its network, based on the Phoenix-RTOS. License agreements to use the system in the mass production of smart meters have been signed.

Similarly, the energy return on investment (EROI) is to be considered.C. Reich-Weiser, D. Dornfeld, and S. Horne. Environmental assessment and metrics for solar: Case study of solfocus solar concentrator systems. UC Berkeley: Laboratory for Manufacturing and Sustainability, 8 May 2008.

During the 20th century, production was 50,000 tonnes, but a strike in 1927 stopped operations entirely. Only in 1935 was it resumed. 1955 a new facility, with sorting plant and concentrator was finished and the annual production reached 600,000 tons.

The argument for concentrated Multi-junction cells has been that the high cost of the cells themselves would be more than offset by the reduction in total number of cells. However, the downside of the concentrator approach is that efficiency drops off very quickly under lower lighting conditions. In order to maximize its advantage over traditional cells and thus be cost competitive, the concentrator system has to track the sun as it moves to keep the light focused on the cell and maintain maximum efficiency as long as possible. This requires a solar tracker system, which increases yield, but also cost.

The concentrator is then said to have a (half) acceptance angle θ, or a total acceptance angle 2θ (since it accepts light within an angle ±θ to the optical axis). Transmission curves Ideally, a solar concentrator has a transmission curve cI as shown in the "transmission curves" figure. Transmission (efficiency) is τ = 1 for all incidence angles α < θI and τ = 0 for all incidence angles α > θI. In practice, real transmission curves are not perfect and they typically have a shape similar to that of curve cR, which is normalized so that τ = 1 for α = 0\.

The first sale outside the MIM Holdings group also occurred in 1995, with the sale of three smaller "M1000" IsaMills to Kemira for grinding calcium sulfate at one of its Finnish operations. A fifth M3000 IsaMill was installed in the McArthur River concentrator in 1998 and six more in the Mount Isa lead–zinc concentrator in 1999. The installation of the IsaMills at Mount Isa, together with some other modifications to the lead–zinc concentrator, allowed MIM to stop producing the low-value bulk concentrate in 1996. The IsaMills made possible the development of the McArthur River mine. The first sales to external organisations of the M3000 mills were to Kalgoorlie Consolidated Gold Mines Pty Ltd ("KCGM"), Australia’s largest gold producer and a joint venture of Newmont Australia Pty Ltd and Barrick Australia Pacific that operates the Kalgoorlie "super pit" gold mine in Western Australia and the Gidji Roaster, north of Kalgoorlie.

The first trainload of iron concentrate left Lac Jeannine on December 16, 1960. Concentrate was stockpiled at Port Cartier while the mine and concentrator were gearing up for full production and the first shipload of concentrate departed the port on July 5, 1961.

An oxygen concentrator is a device that concentrates the oxygen from a gas supply (typically ambient air) by selectively removing nitrogen to supply an oxygen-enriched product gas stream. Two methods in common use are pressure swing adsorption and membrane gas separation.

The Pacific Business News and Green Tech Media reported that the VC-funded micro-concentrator solar power firm was shutting down operations based on statements from its President David Fernandez, however Hitachi Power Systems acquired Sopogy in a private transaction in 2014.

Protected by a couple of aluminum braces and brackets, the concentrator had survived almost completely intact with only one small crack in one of its quadrants. UTTR will also be used as the landing site for the OSIRIS-REx asteroid sample return mission.

Faria changed the terminology of mesmerism. Previously, the focus was on the "concentration" of the subject. In Faria's terminology the operator became "the concentrator" and somnambulism was viewed as a lucid sleep. The method of hypnosis used by Faria is command, following expectancy.

This is the angle (as seen from the PV system's lens or mirror) between the sun's actual location and the spot in the sky that the concentrator is actually pointing at. Skyline's acceptance angle is 1.3° of azimuth and ± 60° of elevation.

Copper is produced from chalcopyrite and molybdenum from molybdenite. Copper oxides include chrysocolla, malachite and azurite. The mine's concentrator has a capacity of 75,000 metric tons per day using stockpile leaching, with pressure leaching for molybdenum. Copper was first mined at the site in 1882.

As of December 2014, the best lab cell efficiency for concentrator MJ-cells reached 46% (four or more junctions). Under outdoor, operating conditions, CPV module efficiencies have exceeded 33% ("one third of a sun"). System-level AC efficiencies are in the range of 25-28%.

In November 2008, Katanga Mining said they had temporarily suspended mining at Tilwezembe and ore processing at the Kolwezi concentrator due to the depressed price of cobalt. Katanga Mining was purchased by Glencore in 2020 and it was de-listed from the Toronto Stock Exchange.

Solar Systems home page This project will use innovative concentrator dish technology to power 45,000 homes, providing 270,000 MWh/year for A$420 million. Solar Systems has already completed construction of three concentrator dish power stations in the Northern Territory, at Hermannsburg, Yuendumu, and Lajamanu, which together generate 1,555 MWh/year (260 homes, going by the energy/home ratio above). This represents a saving of 420,000 litres of diesel fuel and 1550 tonnes of greenhouse gas emissions per year. The total cost of the solar power station was "A$7M, offset by a grant from the Australian and Northern Territory Governments under their Renewable Remote Power Generation Program".

Primary power for the mission was produced by a new solar array technology, the Solar Concentrator Array with Refractive Linear Element Technology (SCARLET), which uses linear Fresnel lenses made of silicone to concentrate sunlight onto solar cells. ABLE Engineering developed the concentrator technology and built the solar array for DS1, with Entech Inc, who supplied the Fresnel optics, and the NASA Glenn Research Center. The activity was sponsored by the Ballistic Missile Defense Organization. The concentrating lens technology was combined with dual-junction solar cells, which had considerably better performance than the GaAs solar cells that were the state of the art at the time of the mission launch.

The semiconductor material gallium arsenide (GaAs) is also used for single- crystalline thin film solar cells. Although GaAs cells are very expensive, they hold the world record for the highest-efficiency, single-junction solar cell at 28.8%. GaAs is more commonly used in multi-junction solar cells for solar panels on spacecrafts, as the larger power to weight ratio lowers the launch costs in space-based solar power (InGaP/(In)GaAs/Ge cells). They are also used in concentrator photovoltaics, an emerging technology best suited for locations that receive much sunlight, using lenses to focus sunlight on a much smaller, thus less expensive GaAs concentrator solar cell.

As such, the town and mill sit on the western shore of the Britannia Range and defined by the large fjord of Howe Sound. The mining claims were discovered in the 1880s and the Britannia Beach Mining and Smelting Company established in the Edwardian years. Copper was first mined in the area in 1903 and the distance from smelters necessitated the construction of an ore concentrator, a system to deliver ore, and a system to ship the ore concentrate. A primitive concentrator, No. 1, was built in 1904, which was upgraded with two more units, collective known as No.2, built in 1914 and 1915.

They were first to successfully transmit messages from Santa Clara College to San Francisco."Local scientists invent a new system of wireless telegraphy," San Francisco Call, March 6, 1904. Montgomery also patented two gold concentrator devices to assist miners in extracting gold from beach sands (see patent list).

In 1932, the Saint Joseph Lead Company improved the recovery process by introducing an amalgamation-flotation concentrator, ushering in an era of modern production. The Middle Fork road connected Boise with Atlanta in 1938. Talache Mines, Inc., acquired all of the mining operations along the Atlanta Lode in 1939.

He began work on an Australian Mineral Industries Research Association (AMIRA) project on grinding in 1962. This was conducted at Mount Isa Mines (MIM) using circuits in its old concentrator to conduct their experiments. James Foots, the General Manager of Mount Isa Mines supported the project during this time.

The Tintic Standard Reduction Mill--also known as the Tintic Mill or Harold Mill--built in 1920, and only operating from 1921 to 1925, is an abandoned refinery or concentrator located on the west slope of Warm Springs Mountain on the southern edge of Genola, Utah, United States.

The RDA is located in an area of several square miles just South of the city of Lamar, Colorado, in the United States, part of the area proposed for Auger North. It consists of surface detectors (water tanks instrumented with photomultiplier tubes and readout electronics), communication towers, and a building housing the data concentrator and computing. The ten water tanks are instrumented with one photomultiplier tube each to detect the Cherenkov radiation generated by particles in cosmic ray air showers. (The water tanks currently used in the southern Pierre Auger observatory use three photomultiplier tubes each.) The communication towers will test a new way to transport data from the water tanks to the data concentrator.

Research into concentrator photovoltaics has taken place since the mid 1970s, initially spurred on by the energy shock from a mideast oil embargo. Sandia National Laboratories in Albuquerque, New Mexico was the site for most of the early work, with the first modern-like photovoltaic concentrating system produced there late in the decade. Their first system was a linear-trough concentrator system that used a point focus acrylic Fresnel lens focusing on water-cooled silicon cells and two axis tracking. Cell cooling with a passive heat sink and use of silicone-on-glass Fresnel lenses was demonstrated in 1979 by the Ramón Areces Project at the Institute of Solar Energy of the Technical University of Madrid.

The cost of home oxygen is about US$150 a month in Brazil and US$400 a month in the United States. Home oxygen can be provided either by oxygen tanks or an oxygen concentrator. Oxygen is believed to be the most common treatment given in hospitals in the developed world.

The blue fluorescence of Tm-doped calcium sulfate has been used in personal dosimeters for visual monitoring of radiation. Tm-doped halides in which Tm is in its 2+ valence state, are promising luminescent materials that can make efficient electricity generating windows based on the principle of a luminescent solar concentrator, possible.

The miners were rounded up and once again herded into a bullpen. Some of the miners were released after denying that they belonged to any subversive organization. Boyce was charged with conspiring to blow up the concentrator. Boyce had been in Wardner conferring with local union officers only a week before the explosion.

The first concentrator was built and a "baby" gauge railroad connected the DCC mines with the transport system of the neighboring Arizona Copper Company, which connected to the transcontinental Southern Pacific Railroad. Church had made his DCC into one of the early, respectable copper operations in the territory. In 1897, he sold his 55% interests in the DCC to Phelps Dodge for a reported $800,000, retired to his stone mansion in Denver's capitol hill neighborhood, and earned a reputation as philanthropist and real estate baron. James Douglas became president and general manager of the operation for Phelps Dodge, which increased the DCC capital stock from $500,000 to one million dollars, and over the next four years greatly expanded DCC operations with a new rail connection, concentrator, and improved, rebuilt smelter. Metallurgist and Douglas protege, Dr. L.D. Ricketts designed the 600 ton Yankee concentrator, one of the most innovative of the time, and the first of many modern, ever enlarging plants built in the district (steel beams with iron sheeting, Wilfley tables, vanners and jigs for gravity concentration, which could work ores under 3% copper).

Interactive use of VS/9 was done through terminals connected to a terminal concentrator unit, which passed control signals to and from the terminals, in a manner similar to the way IBM would provide with its IBM 3270-style terminals. This provided, in general, for input to the terminal to be sent in response to an enter key, as opposed to the practice on PCs of taking input one character at a time. The concentrator unit was originally known as the Communications Control Module, or CCM. However, RCA had sold the patents and designs for its CCM terminal controller to Singer Corporation, so Univac developed an emulator device for the CCM which was known as the Multiterminal Connection Controller model 16, or MCC-16.

Before placing a new concentrator on the market, all oxygen concentrator manufacturers need to make a 510(k) premarket submission to the US Food and Drug Administration (FDA). If the manufacturer chose to apply ISO 80601-2-69:2014 to demonstrate the safety of the new device, the fire safety elements of the standard, including ‘a means to extinguish a tubing fire and isolate the oxygen flow’ are a requirement. Approval to market the product would then be based upon compliance to the standard. In March, 2018, the US Veterans Health Administration issued a Patient Safety Alert mandating the use of thermal fuses in all its patients' home oxygen installations, unless there is a clinical reason for not doing so.

Another economic measure, closely related to the energy payback time, is the energy returned on energy invested (EROEI) or energy return on investment (EROI),C. Reich-Weiser, D. Dornfeld, and S.

In low concentration systems, tracking accuracy must be in the ± 2.0° range to deliver 90% of the rated power output. As a result, high accuracy tracking systems are typical. ;Technologies supported Concentrated photovoltaic trackers are used with refractive and reflective based concentrator systems. There are a range of emerging photovoltaic cell technologies used in these systems.

The BHP Nevada Railroad was a shortline railroad that operated in Nevada from 1996 to 1999. BHP acquired the line from the Northern Nevada Railway. The railroad hauled copper ore concentrate from BHP's concentrator at Riepetown to Shafter, Nevada. At Shafter the railroad interchanged with the Union Pacific and the ore continued to BHP's smelter at San Manuel, Arizona.

KMC made relatively low investment in these properties, continuing to operate the already-functioning Kamoya Mine but not opening the others. In March 2002 the DRC authorities took back control of the Kambove concentrator from Tremalt following a complaint by the manager of KMC against Gecamines at the International Centre for the Settlement of Investment Disputes.

L2TP does not provide confidentiality or strong authentication by itself. IPsec is often used to secure L2TP packets by providing confidentiality, authentication and integrity. The combination of these two protocols is generally known as L2TP/IPsec (discussed below). The two endpoints of an L2TP tunnel are called the LAC (L2TP Access Concentrator) and the LNS (L2TP Network Server).

1,269 drillholes have been sunk on the Ruashi property over the years, and further drilling was conducted in 2003 and in 2005 to confirm asset size estimates. The project was developed in two phases. In the $31 million first phase, a concentrator was built at Ruashi using idle plant from O'okiep. This was to initially process existing oxide stockpiles.

Mining of the original Bethlehem Copper pits ceased in 1982. The Bethlehem concentrator continued to operate on ore from the Valley Copper deposit until June 1989. Production on the Valley Copper mine, now the largest mine and most noticeable feature, began in January 1983. For fifty years the ore was dug using shovels and open pit methods.

To feed the large new works, dozens of miles of tunnels were cut to ore bodies. The adits stretch high into the mountains and down in the mountain below sea level. Large fans for ventilation, electric lights, pumps and air drills assisted the work. At No. 3 Concentrator, ore was crushed and pulverised in ball mills.

The concentrator unit consists of four main sub-systems: line modules, digital concentrator switch, digital line termination (DLT) units and control unit. Its purpose is to convert speech from analogue signals to digital format, and concentrate the traffic for onward transmission to the digital local exchange (DLE). It also receives dialled information from the subscriber and passes this to the exchange processors so that the call can be routed to its destination. In normal circumstances, it does not switch signals between subscriber lines but has limited capacity to do this if the connection to the exchange switch is lost. Each analogue line module unit converts analogue signals from a maximum of 64 subscriber lines in the access network to the 64 kilobit/s digital binary signals used in the core network.

The main industrial and export activity takes place at CODELCO's El Teniente mine, which contributes 7.7% of Chile's copper production. The ore is processed at the Sewell and Colón concentrator plants, smelted and refined at Caletones, and shipped from the port of San Antonio, in the Valparaíso Region. Byproducts include molybdenum and silver. Agriculture contributes 30.1% of the region's GDP.

Having a concentrator near a subscriber's telephone results in very low signal degradation before the analog signal is digitized. This provides reliably good voice quality. Concentrators are often placed alongside a digital subscriber line access multiplexer (DSLAM). This can provide access to asymmetric digital subscriber line (ADSL) Internet service for subscribers who are beyond the normal signaling limit on a copper wire loop.

On 1 April 2000, Mopani purchased the ZCCM assets at Mufulira and Nkana, consisting of the underground mine, concentrator, smelter, refinery and cobalt plant, from the government.

A concentrator system has the advantage to reduce the amount of PV cells needed. Therefore it is possible to use more expensive and efficient PV cells, e.g. multi-junction photovoltaic cell. The concentration of sunlight also reduces the amount of hot PV-absorber area and therefore reduces heat losses to the ambient, which improves significantly the efficiency for higher application temperatures.

A Japanese consortium operated the mine from 1968 to 1983. They developed a vertical mine shaft as well as underground workings and ground- level infrastructure. A surface-level concentrator had a capacity of 1.5 million tonnes per year. At its peak, in 1976 the mine produced 1.67 million tonnes of ore graded at 2.5% copper, equivalent to 38,000 tonnes of finished copper.

The Met Site was built away from the mine because of the muskeg-like terrain surrounding the mine. The Met Site processes material from the Kidd Mine and outside sources, and employs 875 people. Of the 875 employees 125 work at the concentrator, 205 in the copper operations and 275 in the zinc facilities. The remainder of the employees are support staff.

In the European Union the fitting of firebreaks is a legal requirement for all home oxygen installations. All economic operators in the EU, including home oxygen service providers, must comply with the Medical Device Directive (93/42/EEC) or the Medical Device Regulation (2017/745). The instructions for use for an oxygen concentrator placed on the EU single market must include an instruction to the effect that a firebreak shall be fitted close to the patient to stop the flow of oxygen in the event of a fire. By including this statement the oxygen concentrator manufacturer is complying with the harmonised EN ISO type standard for oxygen concentrators EN ISO 8359:2009+A1:2012, which provides the manufacturer with an immediate presumption of conformity to the Essential Requirements of the Medical Devices Directive and allows them to properly apply the CE mark.

This can also be a "hub" which, as a concentrator, enables the connection of classic switching sensors and actuators. An IO-Link device can be an intelligent sensor, actuator, hub or, due to bidirectional communication, also a mechatronic component, e.g. a gripper or a power supply unit with IO-Link connection. Intelligent with regard to IO-Link means that a device has identification data e.g.

The modules performing best under lab conditions in 2014 were made of monocrystalline silicon. They were 7 percentage points above the efficiency of commercially produced modules (23% vs 16%) which indicated that the conventional silicon technology still had potential to improve and therefore maintain its leading position. The best lab module efficiencies for multi- junction modules with concentrator technology in 2014 reached 36.7 percent efficiency.

While Wilson was an English concentrator at Harvard University, he met John Munson and Elaine Harris and formed the band Trip Shakespeare. After the breakup he was a drummer for a Minneapolis band called Polara. He also produced albums for Steel Shank, Magnet, The Wonsers, and Velma. In 1998, he released an album called Burnt, White and Blue on his own label, Planet Maker Records.

The target was to produce 100,000 tonnes per year of copper cathode. By the end of March, 2008, CAMEC had invested $200 million in Luita, and had three SX/EW copper cathode trains in operation, and a small cobalt concentrator. Eventually there were plans for nine copper cathode trains and one cobalt train, each wide and in length. The under-roof plant will be in size.

In some countries, telemetry is used to measure the amount of electrical energy consumed. The electricity meter communicates with a concentrator, and the latter sends the information through GPRS or GSM to the energy provider's server. Telemetry is also used for the remote monitoring of substations and their equipment. For data transmission, phase line carrier systems operating on frequencies between 30 and 400 kHz are sometimes used.

Conventional mining referred to the original part of operations of the Sullivan Mine, where miners drilled and moved ore by hand and with small equipment. The ore was then shipped via an extensive narrow gauge underground rail system which led to the surface and then on to the Marysville concentrator. At one time there were more than of rail underground. Conventional tunnels were standard square.

Aktogay Mine is a copper mine under production in the Karaganda Region (, Қарағанды облысы) of Kazakhstan. It is an "open-pit" type quarry currently under development.

Triple- junction GaAs solar cells were used as the power source of the Dutch four-time World Solar Challenge winners Nuna in 2003, 2005 and 2007 and by the Dutch solar cars Solutra (2005), Twente One (2007) and 21Revolution (2009).

2015 Roughly 85% of the apatite concentrate is processed on-site in Siilinjärvi to produce phosphoric acid and fertilisers, the rest of the concentrate is used in the company's other factories. The by-products are mica and calcite concentrates.Salo 2016 Apatite concentrate is produced by flotation in the concentrator near the Särkijärvi pit. The concentrate can be then processed into phosphoric acid using sulphuric acid.

The site at Fire Lake does not have a crusher or concentrator. Instead, the raw ore in shipped by train to Mont-Wright for processing, typically four times a day in convoys of about 60 wagons. After being crushed and concentrated, the ore is taken by train to Port-Cartier. Fire Lake North, which adjoins the ArcelorMittal property to the north, is operated by Champion Iron.

The use of steel grinding media can cause problems in the subsequent flotation processes that are used to separate the various minerals in an ore, because the iron from the grinding medium can affect the surface properties of the minerals and reduce the effectiveness of the separation.N W Johnson, M Gao, M F Young and B Cronin, "Application of the ISAMILL (a horizontal stirred mill) to the lead–zinc concentrator (Mount Isa Mines Limited) and the mining cycle," in: AusIMM ’98 – The Mining Cycle, Mount Isa, 19–23 April 1998 (The Australasian Institute of Mining and Metallurgy: Melbourne, 1998), 291–297. The IsaMill avoids these contamination-related performance issues through the use of an inert grinding medium. First used in the Mount Isa lead–zinc concentrator in 1994, by May 2013 there were 121 IsaMill installations listed in 20 countries, where they were used by 40 different companies.

The liberation of sphalerite (zinc sulfide) grains dropped from over 70% to just over 50% between 1984 and 1991. As a result, the Mount Isa lead–zinc concentrator was forced to produce a bulk concentrate from the beginning of 1986 until late 1996. Bulk concentrates cannot be treated in electrolytic zinc smelters, due to their lead content, and are typically treated in blast furnaces using the Imperial Smelting Process.

A large intake captures wind and funnels it to a concentrator that ends in a Venturi section and finally wind exits from a diffuser. Turbine(s) are placed inside the Venturi section of the INVELOX. Inside the Venturi the dynamic pressure is high while the static pressure is low. The Turbine converts dynamic pressure or kinetic energy to mechanical rotation and thereby to electrical power using a generator.

Cadia East underground materials handling system is fully automated by Yokogawa Stardom system. Yokogawa Centum VP graphics is used as the main operator interface.

Oxygen sensors are used in oxygen analyzers, which find extensive use in medical applications such as anesthesia monitors, respirators and oxygen concentrator so. Oxygen sensors are also used in hypoxic air fire prevention systems to continuously monitor the oxygen concentration inside the protected volumes. There are many different ways of measuring oxygen. These include technologies such as zirconia, electrochemical (also known as galvanic), infrared, ultrasonic, paramagnetic, and very recently, laser methods.

Unfortunately, the film was neither a critical nor financial success, losing over $300,000 for RKO. In addition, reviews for the film were mixed, with most being not kind to the film. Some modern sources also consider the film to be one of the worst produced by RKO that year. Although the film was not a success, it did introduce two technological advancements to film: the concentrator microphone and the Dunning process.

Reflectors are placed behind the converter and anywhere else in the system that photons might not be efficiently directed to the collector. These photons are directed back to the concentrator where they can be converted, or back to the emitter, where they can be reabsorbed to generate heat and additional photons. An optimal TPV system would use photon recycling and selective emission to convert all photons into electricity.

These figures fell to 0.75–3.5 years in 2013, with an average of about 2 years for crystalline silicon PV and CIS systems.

The residential areas and the mining operation were physically interrelated, resulting in coincidental mining and community disasters through its history. Today, the town is host to the Britannia Mine Museum, formerly known as the British Columbia Museum of Mining, on the grounds of the old Britannia Mines. The mine's old Concentrator facilities, used to separate copper ore from its containing rock, are a National Historic Site of Canada.

The Kidd Metallurgical Site (or Met Site) is a metallurgical facility in Timmins, Ontario, Canada. It was built in 1980 and owned and operated by Xstrata Copper, following their 2006 takeover of Falconbridge Ltd. The site employs approximately 675 hourly employees. The plant is southeast of the Kidd Mine, and houses a concentrator, copper smelter and refinery, zinc plant, cadmium plant, indium plant and a sulphuric acid plant.

The Eubank Landfill Solar Array is a photovoltaic power station in Albuquerque, New Mexico that consists of 1.0 MWAC of concentrator photovoltaics (CPV) and 1.0 MWAC of flat-panel silicon photovoltaics (PV). It is the only utility-scale CPV system utilizing Suncore third-generation technology that is operational and grid-connected in the US. A portion of the output is being sold to PNM under a Power Purchase Agreement.

A fire in 1921 destroyed these, and a concrete and steel structure to house a new concentrator was completed (immediately to the right of the 1914 plant) in early 1923. In the late 1920s, Britannia Mines was the most productive copper mine in the British Empire, and it also produced silver and gold. Now owned by the Britannia Beach Historical Society, it is part of the Britannia Mine Museum.

The joint venture was to extract cobalt from Mukondo, reopen the Kakanda concentrator and control the Luita copper cobalt SX/EW facility. In February 2008 the two companies announced that the Mukondo Mountain operations had restarted. In July 2008 CAMEC said the Luita facility, due to be completed later that year, would be the largest of its kind in the world. The target was to produce 100,000 tonnes per year of copper cathode.

The extracted ore is treated at the Kennecott smelter at nearby Magna, Utah. The ore is run through a concentrator, where huge grinding mills reduce it to the consistency of face powder. Flotation then separates the gangue from the metalliferous particles, which float off as a 28-percent concentrate of copper along with lesser amounts of silver, gold, lead, molybdenum, platinum and palladium. A selective flotation step separates the molybdenite (molybdenum disulfide) from the chalcopyrite.

PADI stands for PPPoE Active Discovery Initiation. If a user wants to "dial up" to the Internet using DSL, then their computer first must find the DSL access concentrator (DSL-AC) at the user's Internet service provider's point of presence (POP). Communication over Ethernet is only possible via MAC addresses. As the computer does not know the MAC address of the DSL-AC, it sends out a PADI packet via an Ethernet broadcast (MAC: ff:ff:ff:ff:ff:ff).

Golmud CPV Solar Park is a 138 MWp (~110 MWAC) concentrator photovoltaics power station located near Golmud City in Haixi Prefecture, Qinghai Province, China. It is the largest operating CPV facility in the world, and was constructed in two phases by Suncore Photovoltaics starting in 2012. It is situated at an elevation of about 2,800 meters (9,200 ft) on the Tibetan plateau near the Gobi Desert with several other conventional photovoltaic power stations.

Lea (Fries) has been suffering from cystic fibrosis since her childhood. She is 22 years old now and has to live in constant fear of suffocation despite using an oxygen concentrator. Although taking pills to diminish her symptoms, Lea can barely fulfill everyday tasks like climbing stairs without having to catch her breath after a short while. Her older brother who suffered from the same disease died several years ago after a lung transplant.

Two new technological improvements were inaugurated in this film. The "Dunning Process" was used to adapt the film for foreign-language versions. The concentrator microphone was developed by RKO to be used in productions to filter noise in exterior shots, was first used during this film's production. In addition to Brenon directing and Schofield writing both films, J. Roy Hunt was the cinematographer on both the 1926 Beau Geste and this film.

To accommodate the TB cases, there is a 24-bed TB ward that serves these patients exclusively. In their lab, doctors and staff research and conduct 27,000 tests each year. The EMMS has focused on purchasing necessary equipment, constructing new space, and providing funds for the hospital staff and training. The equipment that the EMMS has purchased includes a baby resuscitation equipment, a defibrillator, ECG machine, an anaesthetic machine, and an oxygen concentrator.

It is on the World Health Organization's List of Essential Medicines, the safest and most effective medicines needed in a health system. The cost of home oxygen is about US$150 a month in Brazil and US$400 a month in the United States. Home oxygen can be provided either by oxygen tanks or an oxygen concentrator. Oxygen is believed to be the most common treatment given in hospitals in the developed world.

It was widely believed that the area would become the greatest lead-silver district in the Western Hemisphere. Elaborate cable-bucket aerial tramways were built over Mystery Ridge for hauling ore to the town site, carrying as much as 230 tons every day. A five- level concentrator was completed in 1894 at the Monte Cristo townsite. Ore was shipped out via the newly completed railway, 42 miles long from Monte Cristo to Hartford.

From this wealth, came a complete town, with schools, churches, post office, houses, recreation halls and hunting lodges. The mines themselves needed support buildings; power houses, boiler houses, blacksmith shops, machine shops, concentrator buildings and so on. Over one hundred miles of tunnels were dug in the forty or so years of operation. As Bralorne sits on a volcanic fault, the shafts were quite warm inside: 40 degrees C was not unknown.

In most areas, one carrier held a monopoly on local service. The landline telephone system was originally constructed in an era before transistorisation, remote concentrators or cabinetisation. Individual lines from subscribers ran not to a remote concentrator but directly to the nearest village community dial office, to be terminated at an automated mechanical switch or manual exchange. To keep subscriber loop wiring requirements manageable, local exchanges were built in each tiny hamlet.

Actual efficiency is influenced by temperature, irradiance and spectrum. The most efficient type of solar cell to date is a multi-junction concentrator solar cell with an efficiency of 46.0% produced by Fraunhofer ISE in December 2014. The highest efficiencies achieved without concentration include a material by Sharp Corporation at 35.8% using a proprietary triple-junction manufacturing technology in 2009,Sharp Develops Solar Cell with World's Highest Conversion Efficiency of 35.8%.

"Improving fine particle gravity recovery through equipment behaviour modification." Proceedings of the 38th Annual Meeting of the Canadian Mineral Processors, Paper 31, 501-517 All models of Falcon Concentrator rely on the creation of centrifugal forces by way of a rapidly rotating, vertical bowl in order to stratify and separate particles based on weight. The amount of gravitational force generated and the method of collecting these heavier particles differs for each model.

Several attempts were made to revive the Holden plant as a concentrator, where the lower-grade ore could be stripped out. After the last one failed, in 1904 the property was abandoned, like so many others in the once-prosperous city. By 1930 less than a thousand people lived in Aspen. Buildings from the boom years such as the plant stood vacant and deteriorating, many long since foreclosed by the county for nonpayment of taxes.

Nickel West is a division of BHP Billiton. In Western Australia, BHP Billiton's nickel operations are combined under the Nickel West Operation which includes Mount Keith Nickel Mine, Leinster Nickel Mine, Kambalda Nickel Concentrator, Kalgoorlie Nickel Smelter and Kwinana Nickel Refinery. Production figures published by the company at the end of 2008 are for the whole Nickel West Operations and not broken down to individual mines. In the calendar year 2008 Nickel West produced 85,800 tonnes of nickel.

Unlike ARPANET, X.25 was commonly available for business use. Telenet offered its Telemail electronic mail service, which was also targeted to enterprise use rather than the general email system of the ARPANET. The first public dial-in networks used asynchronous TTY terminal protocols to reach a concentrator operated in the public network. Some networks, such as CompuServe, used X.25 to multiplex the terminal sessions into their packet-switched backbones, while others, such as Tymnet, used proprietary protocols.

Simeon Reed bought the Bunker Hill Mine and Mill, and incorporated the Bunker Hill and Sullivan Mining and Concentrating Company on 29 July 1887. John Hays Hammond was hired to manage the mine, and a new concentrator, The Old South Mill, became operational in 1891, capable of 150 tons per day. Hammond became president on 2 July 1891, followed by Gen. Nathaniel H. Harris on 15 June 1893, when company headquarters were located in San Francisco.

To speed up the weathering process while still using natural weather conditions, accelerated natural testing can be applied. One method uses mirrors to amplify available UV radiation. A device known as a Fresnel-reflecting concentrator uses photo- receptor cells to maintain alignment with the sun and 10 mirrors to reflect sunlight onto the test specimens. With the latest technology for ultra- accelerated exposure testing it is possible to simulate 63 years of UV radiation exposure in a single year.

Overall layout of the project Touwsrivier CPV Solar Project is a 44 MWp (36 MWAC) concentrator photovoltaics (CPV) power station located 13 km outside the town of Touwsrivier in the Western Cape of South Africa. The installation reached full capacity in December 2014 and is the second largest operating CPV facility in the world. Electricity produced by the plant is fed into the national grid operated by Eskom under a 20-year power purchase agreement (PPA).

The Marula Mine is a platinum mine located in the Limpopo province of South Africa. It is in the eastern limb of the Bushveld Igneous Complex, approximately 35km north-west of Burgersfort. The operation comprises two decline shaft systems which are used to access the UG2 reef. In the 2018 financial year the concentrator plant at Marula mine produced 85 100 oz of platinum, which was processed at Impala Platinum's Mineral Processes in the town Rustenburg.

A terminal concentrator was also developed that year, since time-sharing was still a prevalent mode of computer use. In 1975, the network shrank slightly due to budgetary constraints, but the setback was only temporary. At that point, the network provided remote login, remote batch and file transfer user application services. By 1976 the network was in full deployment, eventually numbering 20 nodes with connections to NPL in London, ESA in Rome, and to the European Informatics Network (EIN).

Concentrator photovoltaics (CPV) (also known as concentration photovoltaics) is a photovoltaic technology that generates electricity from sunlight. Unlike conventional photovoltaic systems, it uses lenses or curved mirrors to focus sunlight onto small, highly efficient, multi-junction (MJ) solar cells. In addition, CPV systems often use solar trackers and sometimes a cooling system to further increase their efficiency. Ongoing research and development is rapidly improving their competitiveness in the utility-scale segment and in areas of high insolation.

Although traditional PPP is a peer-to-peer protocol, PPPoE is inherently a client-server relationship since multiple hosts can connect to a service provider over a single physical connection. The discovery process consists of four steps between the host computer which acts as the client and the access concentrator at the Internet service provider's end acts as the server. They are outlined below. The fifth and last step is the way to close an existing session.

For the analysis of volatile compounds, a purge and trap (P&T;) concentrator system may be used to introduce samples. The target analytes are extracted by mixing the sample with water and purge with inert gas (e.g. Nitrogen gas) into an airtight chamber, this is known as purging or sparging. The volatile compounds move into the headspace above the water and are drawn along a pressure gradient (caused by the introduction of the purge gas) out of the chamber.

These comparisons can be used to assess system conditions-such as; frequency changes, MW, MVARs, kVolts, etc. The monitored points are preselected through various studies to make extremely accurate phase angle measurements to indicate shifts in system (grid) stability. The phasor data is collected either on-site or at centralized locations using Phasor Data Concentrator technologies. The data is then transmitted to a regional monitoring system which is maintained by the local Independent System Operator (ISO).

The Sepro Leach Reactor is a high concentration leach reactor developed to treat the gold concentrate produced by the Falcon Concentrator. The unit consists of a concentrate holding tank and a leach tank and impeller which are linked by a Sepro vertical bowl pump. The SLR uses either peroxide or oxygen gas to achieve elevated levels of dissolved oxygen required to accelerate the leaching process with no reagents required. The pregnant leach solution produced can be directly electrowon.

The Questa Solar Facility is a 1.17 MWp (1.0 MWAC) concentrator photovoltaics (CPV) power station in Questa, New Mexico. Upon its completion in late 2010, it was one of the largest CPV facilities in the world, and the first utility- scale installation of Concentrix Solar technology in the United States. Annual electricity production is expected to average about 2.1 GW·h, and is being sold to the Kit Carson Electric Cooperative under a 20-year power purchase agreement (PPA).

The Britannia Mines Concentrator is a National Historic Site of Canada. The large, inclined gravity mill was built on the northwest side of Mount Sheer to assist the transfer of copper ore through the chemical and mechanical processes of the plant. It is a landmark in Britannia Beach, British Columbia some forty-five kilometers north of Vancouver. The nearby volcanic peak of Mount Garibaldi indicates the presence of magmatic inclusions and volcanic cores, in which copper is usually found.

In high-altitude conditions, oxygen enrichment can counteract the hypoxia related effects of altitude sickness. A small amount of supplemental oxygen reduces the equivalent altitude in climate-controlled rooms. At (), raising the oxygen concentration level by 5% via an oxygen concentrator and an existing ventilation system provides an effective altitude of (), which is more tolerable for those unaccustomed to high altitudes. Oxygen from gas bottles or liquid containers can be applied directly via a nasal cannula or mask.

The development of the IsaMill was driven by MIM Holdings’ desire to develop its McArthur River lead–zinc deposit in Australia’s Northern Territory, and by the need for finer grinding at its Mount Isa lead–zinc concentrator. The mineral grains in the McArthur River deposit were much finer than those of operating mines. Test work had shown that it would be necessary to grind part of the ore so that 80% of the ground particles were less than 7 µm (0.007 mm) if a saleable concentrate of mixed lead and zinc minerals (referred to as a "bulk concentrate") were to be produced. At the same time, the mineral grain size of the lead–zinc ore mined and processed at Mount Isa was decreasing, making it harder to separate the lead and zinc minerals.M F Young, J D Pease, N W Johnson and PD Munro, "Developments in milling practice at the lead–zinc concentrator of Mount Isa Mines Limited from 1990," in: 6th Mill Operators’ Conference, Madang, 6–8 October 1997 (The Australasian Institute of Mining and Metallurgy: Melbourne, 1997), 3–12.

The sensitivity of graphene chemical gas sensors can be dramatically enhanced by functionalization, for example, coating the film with a thin layer of certain polymers. The thin polymer layer acts like a concentrator that absorbs gaseous molecules. The molecule absorption introduces a local change in electrical resistance of graphene sensors. While this effect occurs in other materials, graphene is superior due to its high electrical conductivity (even when few carriers are present) and low noise, which makes this change in resistance detectable.

From here the ore was conveyed to the three No.1 Concentrator mills. The Urquhart shaft's Uskside Winding Engine, which was housed in a shed immediately to the north of the headframe, has been removed from the site and installed at the "Outback@Isa Explorers Park" tourist facility in the town. The original corrugated iron winding shed which had been replaced by more recent ribbed steel sheets on the former frame and concrete surface, has also been removed from the site.

The Astronomical Roentgen Telescope X-ray Concentrator (ART-XC) is an X-ray telescope with a grazing incidence mirror that is capable of capturing high energy X-ray photons within the 5-30 keV energy range. This telescope is one of the two X-ray telescopes on the Spektr-RG (SRG) mission. The other telescope that SRG carries is eROSITA. The observatory was launched on 13 July 2019 via a Proton rocket from the Russian launch site Baikonur in Kazakhstan.

However, this efficiency is gained at the cost of increased complexity and manufacturing price. To date, their higher price and higher price-to-performance ratio have limited their use to special roles, notably in aerospace where their high power-to-weight ratio is desirable. In terrestrial applications, these solar cells are emerging in concentrator photovoltaics (CPV), with a growing number of installations around the world."Concentrating Photovoltaic Technology" , NREL Tandem fabrication techniques have been used to improve the performance of existing designs.

Because of the high costs associated with processing, the businessmen approached Oliver Iron Mining Company with an investment opportunity. In 1904, Oliver invested $10 million in a concentration plant that would serve this area, which the corporation referred to as the "Canisteo District". The plant, called the Trout Lake Concentrator, transformed the region, helping existing towns like Bovey and Calumet grow. In addition, the towns of Coleraine, Marble, and Taconite were directly built by Oliver to house workers in the newly developing region.

The Aktogay mine (, Aqtoǵaı mys ken orny) is a large open-pit mine located in south eastern Kazakhstan in East Kazakhstan Province approximately 250 km from Kazakhstan - China border. Aktogay is KAZ Minerals's second major growth project. The Aktogay ore body consists of an oxide deposit on top of a larger sulphide deposit, the latter containing some valuable molybdenum as a by- product. The project will include an open-pit mine and concentrator and has a production life of over 50 years.

At its prime, Winfield included three saloons, three stores, a post office, two hotels, a boarding house, mill, smelter, concentrator, church and a school, which is now a museum containing school furnishings and displays. This museum is restored and operated by the Clear Creek Historical Society of Chaffee County. The Ball cabin across the street from the school house is also a museum of the mining era. The Silver market crash in 1893 halted the mining activity in Clear Creek Canyon.

Instead of functioning as a light concentrator, this performs the function of conventional lens imaging with a 1 to 1 correspondence, albeit with a point source. However, resolution of more complicated structures can be achieved as constructions of multiple point sources. The fine details, and brighter image, that are normally associated with the high numerical apertures of conventional lenses can be reliably produced. Notable applications for this technology arise when conventional optics is not suitable for the task at hand.

In 1887, she married Levi "Al" Hutton, one of her customers. They moved to Wallace, Idaho where she oversaw the dining hall of the Wallace Hotel and her husband worked for the Northern Pacific Railroad. May and Al were part of a group of miners that struck it rich when discovering a vast silver mine. When miners dynamited the Bunker Hill and Sullivan's mine concentrator in Wardner, Idaho, Al was the engineer of the train used to deliver the dynamite.

Reflective mirror concentrator units This device uses multiple mirrors in a horizontal plane to reflect sunlight upward to a high temperature photovoltaic or other system requiring concentrated solar power. Structural problems and expense are greatly reduced since the mirrors are not significantly exposed to wind loads. Through the employment of a patented mechanism, only two drive systems are required for each device. Because of the configuration of the device it is especially suited for use on flat roofs and at lower latitudes.

The year 1896 was prosperous but in November major flooding damaged or destroyed railroad tunnels and track. Mining output reached record levels in 1897 but again intense autumn floods devastated the region's infrastructure, the repair of which cut deeply into mining profits. Other problems such as metallic impurities at the Monte Cristo concentrator and the Everett smelter led to the boom collapsing. By 1900 most of the Monte Cristo miners had left for the new mining booms of the Klondike.

February 19, 2017 :A patient died and an apartment was destroyed after medical oxygen cylinders exploded, leading to a fire. Fifteen other residents had to be relocated after the incident. Winchester, Kentucky, US. March 11, 2016 :Patient Jackie Hisle Jr. was sentenced to ten years’ imprisonment on three counts of manslaughter after an incident in which his son, Donald Hisle, and two other residents were killed and six others were injured. Mr Hisle Jr. was smoking while using an oxygen concentrator, despite warnings.

The region's altitude averages about 2600m, the highest spot of which approximates 3000m. Sarcheshmeh ore bodies, situated in the central part of Zagros ranges, consist of folded and faulted early tertiary volcano-sedimentary rocks. Sar Cheshmeh mine was managed by the Anaconda Group until the 1979 revolution in Iran. Design and construction of the processing plant was done by Parsons- Jurden of the US. Production units of Sarcheshmeh Copper Complex involve the mine itself, concentrator, smelter, refinery, foundries and leaching.

Slip in the material is localized at these PSBs, and the exaggerated slip can now serve as a stress concentrator for a crack to form. Nucleation and growth of a crack to a detectable size accounts for most of the cracking process. It is for this reason that cyclic fatigue failures seem to occur so suddenly where the bulk of the changes in the material are not visible without destructive testing. Even in normally ductile materials, fatigue failures will resemble sudden brittle failures.

The Newberry Springs CPV Power Plant is a 1.68 MWp (1.5 MWAC) concentrator photovoltaics (CPV) power station in Newberry Springs, California. It was built by Blattner Energy using 60 dual-axis CX-S530 systems, each of which contains 12 CX-M500 modules. Each module contains 2,400 fresnel lenses to concentrate sunlight 500 times onto multi-junction solar cells, allowing a greater efficiency than other photovoltaic power plants. The output is being sold to Southern California Edison under a 20-year Power Purchase Agreement.

An edge device is a device which provides an entry point into enterprise or service provider core networks. Examples include routers, routing switches, integrated access devices (IADs), multiplexers, and a variety of metropolitan area network (MAN) and wide area network (WAN) access devices. Edge devices also provide connections into carrier and service provider networks. An edge device that connects a local area network to a high speed switch or backbone (such as an ATM switch) may be called an edge concentrator.

The Victor Valley College Solar Farm is a 1.26 MWp (1.02 MWAC) concentrator photovoltaics (CPV) power station in Victorville, California. Upon completion in May 2010 it was the largest CPV project installed in North America. It was built by Sachs Electric using 122 dual-axis SF-1100S systems, each of which contains 28 SF-1100 modules. Each module contains reflective optics to concentrate sunlight 650 times onto multi-junction solar cells, allowing a greater efficiency than other photovoltaic power plants.

The Pronto Mine is an historical uranium mine located approximately 20 km south of Elliot Lake, Ontario near Spragge. The site is owned and operated by Rio Algom Ltd, has been rehabilitated and is currently undergoing environmental monitoring. The mine was in operation from 1956 to 1960, during which time it produced 2.3 million tons of ore. Upon closure of the mine, the mill was converted to a copper concentrator to process ore from the nearby Pater Mine and operated until 1970.

These front-end systems support their own command language of "device commands", usually lines prefixed with a special character such as a percent-sign (%), to allow the user to configure and control the connections. Data Concentrator User's Guide, David L. Mills, Jack L. Di Giuseppe, and W. Scott Gerstenberger, CONCOMP Project, University of Michigan, April 1970 The $CONTROL command and programs running on MTS can use the CONTROL subroutine to issue device commands to front-end and network control units.

The Desert Green Solar Farm is a 8.8 MWp (6.3 MWAC) concentrator photovoltaics (CPV) power station in Borrego Springs, California. It was built by Blattner Energy using 299 dual-axis CX-S530 systems, each of which contains 12 CX-M500 modules. Each module contains 2,400 fresnel lenses to concentrate sunlight 500 times onto multi-junction solar cells, allowing a greater efficiency than other photovoltaic power plants. The output is being sold to San Diego Gas & Electric under a 25-year Power Purchase Agreement.

Prospectors from Silver City, New Mexico discovered copper mineralization at Morenci, also known as the Greenlee district in 1872. Mining began the following year, and miners extracted and smelted high-grade copper ore until a railroad reached the district in 1884 and a concentrator made mining and processing of low-grade ore economical. The Morenci mine, owned jointly by Freeport-McMoran and Sumitomo, is the largest copper producer in the state, and regularly contributes about half of Arizona's copper production.

These secondary sulfides arise from the leaching of the overlying ore and its re-deposition on and replacement of the deeper primary (hypogene) sulfides. In 1957 the Exotica deposit (South Mine) was discovered beneath tailings, which turned out to be the largest known deposit of exotic copper. This led Anaconda to build an oxide plant, concentrator, smelter, refinery, and town, all next to the mine, plus a power plant in Tocopilla. However, in 1971, the mine was nationalized and operations were then assumed by CODELCO.

The Los Colorados concentrator started up at 35,000 tonnes per day in November 1990, and the first concentrate shipment was made at the end of the year. Expansion has been steady since then. In 1994, an ammonia leach plant to produce copper cathode from a portion of the concentrates was started up in Coloso, but was not economic and closed down four years later. In 1998, the oxide ore leaching plant was started up, which now has a capacity of 150,000 tonnes of copper cathode annually.

In November 2007 CAMEC and Prairie International announced plans to form a joint venture to extract cobalt from Mukondo, to reopen Kakanda concentrator and to control the copper cobalt SX/EW facility at Luita. In February 2008 the two companies announced that the Mukondo Mountain operations had restarted. In July 2008 CAMEC said the Luita facility, due to be completed later that year, would be the largest of its kind in the world. The target was to produce 100,000 tonnes per year of copper cathode.

This is due to long and complex CAD flows for synthesis and place and route that can require from 8 to 18 hours to complete. Improved approaches include tools like Certus from Tektronix or EXOSTIV from Exostiv Labs. Certus brings enhanced RTL-level visibility to FPGA-based debugging. It uses a highly efficient multi-stage concentrator as the basis for its observation network to reduce the number of LUTs required per signal to increase the number of signals that can be probed in a given space.

The flow-line (or Winston-Welford) design method typically leads to optics which guide the light confining it between two reflective surfaces. The best known of these devices is the CPC (Compound Parabolic Concentrator). These types of optics may be obtained, for example, by applying the edge ray of nonimaging optics to the design of mirrored optics, as shown in figure "CEC" on the right. It is composed of two elliptical mirrors e1 with foci S1 and R1 and its symmetrical e2 with foci S2 and R2.

Monaco was born in Wilmington, Delaware and graduated from the Salesianum School in 1977. He earned an undergraduate degree as an independent concentrator in neuroscience and behavior at Princeton University in 1981 and played goalie on their men's water polo team. Monaco earned his Ph.D. in Neurobiology in 1987 and his M.D. in 1988 in a joint program from Harvard University. His doctoral research, supervised by Louis M. Kunkel, led to his landmark discovery of the gene responsible for X-linked Duchenne and Becker muscular dystrophy.

Concentrix Solar GmbH was a German solar power company based in Freiburg, Germany that specialized in developing and commercializing concentrator photovoltaics (CPV) technology. In December 2009, Concentrix Solar was acquired by the French Soitec Group. In January 2015, Soitec announced its intention to exit from the CPV business, citing a lack of sales due to competition from lower-cost conventional photovoltaics. An agreed sale of the business to Chinese firm ConcenSolar (an entity having ties with Suncore Photovoltaics) in May 2015 was not completed.

According to data from WoodMackenzie/GTM Research, global solar tracker shipments hit a record 14.5 gigawatts in 2017. This represents growth of 32 percent year-over-year, with similar or greater growth projected as large-scale solar deployment accelerates. In concentrator photovoltaics (CPV) and concentrated solar power (CSP) applications, trackers are used to enable the optical components in the CPV and CSP systems. The optics in concentrated solar applications accept the direct component of sunlight light and therefore must be oriented appropriately to collect energy.

Some other buildings have fallen down, have been burned, or stripped of lumber and fittings. The rusting and derelict ball and concentrator mill, has been cleaned up under the Mine Reclamation Act. Since 2002 rising gold prices have led to new exploration in the area and plans for re-opening the Bralorne Mine, and nearby Pioneer Mine.. In 2014, a realtor put the Bralorne's "third townsite", Bradian, on sale for $1 million. Recently, the entire town was sold for just over one million dollars.

In the solar energy market, Soitec manufactured and supplied Concentrator Photovoltaic (CPV) systems from 2009 to 2015. Research conducted in order to create a new generation of four-junction solar cells led Soitec to set a world record in December 2014 with a cell capable of converting 46% of solar rays into electricity. Soitec announced in January 2015 that it would be leaving the solar market after several important solar plant projects ended. In the lighting industry, Soitec operates upstream and downstream of the LED value chain.

The state-owned Gécamines started operating a mineral concentrator at Kolwezi in 1952, taking ores from the western Katanga open pit mines and producing copper concentrates. The tailings still contain significant amounts of metal. The project entails construction of a plant to process the copper and cobalt tailings in the Kingamyambo tailings dam and the Musunoi river tailings, which have an estimated total metal content of 1,676,000 tonnes of copper and 363,000 tonnes of cobalt. A Durban company, Metso ND Engineering, was selected to build the equipment.

In telephony, a customer's telephone line now typically ends at the remote concentrator box, where it is multiplexed along with other telephone lines for that neighborhood or other similar area. The multiplexed signal is then carried to the central switching office on significantly fewer wires and for much further distances than a customer's line can practically go. This is likewise also true for digital subscriber lines (DSL). Fiber in the loop (FITL) is a common method of multiplexing, which uses optical fiber as the backbone.

Three years after his death, in 1932, Hull's son Carroll M. Hull was named to the Board. Carroll Hull remained on the Board of Sunshine until February 1965. Following the death of Sawbridge in 1931, Larson became President and served the company in that capacity until his own death in 1934. At that time Robert M. Hardy (a Yakima native and President of the Yakima National Bank) became President. He would remain President until his resignation in 1956, at which time his son succeeded him as President of the Company In 1921 a 25-ton per day mill was constructed. The mill was later expanded piecemeal and eventually reached a daily capacity of 500 tons. Soon after the concentrator was commissioned, the Sunshine tunnel was driven from the surface in an exploration effort which discovered higher quality ore historically identified as "Chinatown" In 1935 the concentrator at the mine was upgraded with new ball mill grinding units and flotation cells increasing the capacity to 1,000 tons per day while attaining a recovery of 98%. The sinking of the new four-compartment vertical Jewell shaft was started, reaching the 2300 level in 1936.

The majority of the installations are in mainstream inert-grinding applications, producing relatively coarse product particles sizes (for example, 80% of the particles smaller than 53 µm). Anglo Platinum attributed an increase in recovery at its Rustenburg concentrator of over three percentage points to the installation of the IsaMills there. The M10000 IsaMill has proven very popular and sales of the technology have been strong since it launched onto the global stage. IsaMills are now used in lead–zinc, copper, platinum group metal, gold, nickel, molybdenum and magnetite iron ore applications.

An IBM-compatible tape drive was used to move data to and from the drive as needed, an operation that was also independent of the CPU. Two DECtape units were also available and worked in the same fashion as the IBM drive. Terminals were handled through a custom "concentrator" that consisted of a mechanical Strowger switch that could connect any of the 300 to 400 possible terminal plugs to any of 40 outputs. A further eight lines were dedicated to Teletype Model 33 inputs, as opposed to the JOSS-style Selectrics.

The SG4 dish in 2014 The Big Dish is a parabolic dish concentrator developed by the Australian National University's Solar Thermal Group. The initial prototype, SG3 , was constructed on the Canberra campus of the Australian National University in 1994. A modified version of SG3 was exported to Ben- Gurion National Solar Energy Center at the Ben Gurion University in Israel. In 2006, a joint project led by the Solar Thermal Group with commercial partner Wizard Power, and funding from Australian's Government's Renewable Energy Development Initiative, began the design and construction of SG4 .

Thomas H. Cormen was born in New York City in 1956. He grew up in Oceanside, New York. He received his bachelor's degree summa cum laude in Electrical Engineering and Computer Science from Princeton University in June 1978. He then went to the Massachusetts Institute of Technology, where he earned his master's degree in Electrical Engineering and Computer Science in May 1986 with a thesis on "Concentrator Switches for Routing Messages in Parallel Computers" and his PhD with a thesis on "Virtual Memory for Data-Parallel Computing" in February 1993.

Applied Optics and functional Surfaces Solar energy systems convert solar radiation incident on the earth into thermal, electrical or chemical energy. In order to better transmit, reflect, absorb, filter, redirect or concentrate the incoming radiation, Fraunhofer ISE develops optical components and systems. This business area serves as an interdisciplinary field and serves many areas of solar technology: windows and facades, solar thermal collectors, concentrator systems for photovoltaics and solar power plants as well as photovoltaic module technology. Solar Thermal Systems This business area covers the markets of low and high temperature applications.

Feasibility Study for a Mine and Concentrator Complex at Hemerdon Nr Plymouth, England. Produced for AMAX/HMSL Joint Venture, February 1982 The venture was joined by Billiton Minerals Ltd, providing further finance and expertise, and forming a consortium that planned to commence production in 1986.US Bureau of Mines, Minerals yearbook area reports: international 1983 The initial planning application was made in 1981, but a public enquiry and 'calling in' of the application by the Secretary of State resulted in an initial refusal of the application in 1984.

However, up to now all other options yield lower material qualities and hence lower conversion efficiencies. Further research focusses on the re-use of the InP substrate as template for the production of further solar cells. Also today’s state-of-the-art high- efficiency solar cells for concentrator photovoltaics (CPV) and for space applications use (Ga)InP and other III-V compounds to achieve the required bandgap combinations. Other technologies, such as Si solar cells, provide only half the power than III-V cells and furthermore show much stronger degradation in the harsh space environment.

The Miami mine is owned and operated by Freeport-McMoRan. Mining began in 1911 as the Inspiration mine, and the nation's first froth flotation copper concentrator to process sulfide minerals was built and began production in 1915. Inspiration was among the first to employ vat leaching in 1926 and precipitation plants to recover oxide minerals. Copper was mined underground until after World War II, when the first open-pit mining began. The plant's smelter was modernized in 1974 to meet Clean Air Act standards and further modernized and expanded in 1992.

Solar array mass could be reduced with thin-film photovoltaic cells, flexible blanket substrates, and composite support structures. Solar array efficiency could be improved by using new photovoltaic cell materials and solar concentrators that intensify the incident sunlight. Photovoltaic concentrator solar arrays for primary spacecraft power are devices which intensify the sunlight on the photovoltaics. This design uses a flat lens, called a Fresnel lens, which takes a large area of sunlight and concentrates it onto a smaller spot, allowing a smaller area of solar cell to be used.

President Obama speaking at the funeral service for Inouye A joint military honor guard folds a US flag over Inouye's casket at the National Memorial Cemetery. President Barack Obama, center, looks toward the sky as U.S. Air Force F-22 Raptor aircraft with the 199th Fighter Squadron, Hawaii Air National Guard and the 19th Fighter Squadron perform the missing man formation in honor of U.S. Sen. Daniel K. Inouye during a service. In 2012, Inouye began using a wheelchair in the Senate to preserve his knees, and received an oxygen concentrator to aid his breathing.

The furnace was first opened in May 1981, and it is located 1100 meters above sea level. The furnace covers a huge area in the mountains, and consists of 4 complex subdivisions, which are: the main building of “Solar furnace of Uzbekistan”, heliostatic field, concentrator and manufacturing tower. The solar furnace of Uzbekistan was ready for use in 6 years, which means it was built between the years of 1981 and 1987. The place for the solar furnace of Uzbekistan was chosen carefully, because the sun shines there for 270 days a year.

WINFIELD & VICKSBURG, COLORADO: Two Colorado Ghost Towns In Chaffee County (Photos - July 2006)Vicksburg & Winfield Ghost Towns In Chaffee County, Colorado (Photos on September 29, 2007) Winfield mining camp Winfield was the largest settlement. In 1890 the estimated population is listed as fifteen hundred, but it can be assumed that hundreds more lived in the surrounding area. Winfield included three saloons, three stores, a post office, two hotels, a boarding house, mill, smelter, ore concentrator, church, and a school. The last ore was hauled out by stage in 1918.

In Chile, this incident is known locally as the Smoke Tragedy ().Emol, June 20, 2005, "La Tragedia del Humo": A 60 años del peor accidente minero en Chile (in Spanish) In 1967 the Chilean government bought a 51% stake in the mine and founded Sociedad Minería El Teniente. Under this agreement Kennecott built a new concentrator, and the mine expanded production to per day. On July 11, 1971, President Salvador Allende ordered the Chilean nationalization of copper, in an effort for the country to gain more benefit from the mines.

To celebrate the new railway, a ball was held inside the Northern building, which was still under construction at the time. Additional Ely-area trackage was constructed in 1907-1908 to serve the local mining industry. This trackage, known as the "Ore Line," included a route bypassing Ely to the north and continuing west up Robinson Canyon to the copper mines at Ruth. East of Ely, the Ore Line project saw the construction of the "Hiline," a branch leading to Nevada Consolidated's new copper smelter and concentrator at McGill.

The Aktogay project has a measured and indicated oxide ore resource of 121 MT with a copper grade of 0.37%, and a sulphide ore resource of 1,597 MT at a copper grade of 0.33%. The project will initially develop the deposit’s oxide resource which is located above the sulphide ore body at the SX/WE plant currently under construction. The sulphide resource extracted from the Aktogay mine will be processed at the concentrator on site, currently under construction. Aktogay will employ around 3,000 people at peak construction activity and around 1,500 people when operational.

In conjunction with the oxygen concentrator, she had used a BiPAP machine. On May 29 a contractor for VirCom EMS was sent by Mercury Energy to the Muliaga's house to disconnect the electricity supply. There was an outstanding balance of NZ$168.40. The family had made two payments totaling $106.90 in the last month on their balance, but according to statements later made by Mercury, the outstanding balance was accruing faster than the family were paying it off. The $168 did not include the current month's charges of $136.

In that case, the real acceptance angle θR is typically defined as the angle for which transmission τ drops to 90% of its maximum. For line-focus systems, such as a trough concentrator or a linear Fresnel lens, the acceptance angle is one dimensional, and the concentration has only weak dependence on off-pointing perpendicular to the focus direction. Point focus systems, on the other hand, are sensitive to off-pointing in both directions. In the general case, the acceptance angle in one direction may be different from the other.

Work in 2007 demonstrated that a quasi-periodic array of nanoholes, in a metal screen, were able to focus the optical energy of a plane wave to form subwavelength spots (hot spots). The distances for the spots was a few tens of wavelengths on the other side of the array, or, in other words, opposite the side of the incident plane wave. The quasi-periodic array of nanoholes functioned as a light concentrator. In June 2008, this was followed by the demonstrated capability of an array of quasi-crystal nanoholes in a metal screen.

Mount Keith is part of BHP's Nickel West operations, which includes, apart from Mount Keith, the Leinster Nickel Mine, the Kambalda Nickel Concentrator, the Kalgoorlie Nickel Smelter and the Kwinana Nickel Refinery.Nickel West BHP Billiton website, accessed: 11 December 2009 Production figures published by the company at the end of 2008 are for the whole Nickel West Operations and not broken down to individual mines. In the calendar year 2008 Nickel West produced 85,800 tonnes of nickel. At the time, Nickel West also included the Ravensthorpe Nickel Mine.

UV ozone generators, or vacuum-ultraviolet (VUV) ozone generators, employ a light source that generates a narrow-band ultraviolet light, a subset of that produced by the Sun. The Sun's UV sustains the ozone layer in the stratosphere of Earth. UV ozone generators use ambient air for ozone production, no air prep systems are used (air dryer or oxygen concentrator), therefore these generators tend to be less expensive. However, UV ozone generators usually produce ozone with a concentration of about 0.5% or lower which limits the potential ozone production rate.

A POC system is functionally a nitrogen scrubber capable of consistently producing medical-grade oxygen of up to 90%. A Zen-O portable oxygen concentrator; it is capable of pulse and continuous flow operation The most important consideration for a POC is its ability to supply adequate supplementary oxygen to relieve hypoxia (oxygen deficiency) during normal activities and based on the patients breathing cycles. Other variables include maximum oxygen purity, the number and increment of settings for adjusting oxygen flow, and battery capacity (or number of add-on batteries) and power cord options for recharging.

Since 2015 FRENELL GmbH, a management buy-out of Novatec Solar took over the commercial development of the direct molten salt technology. Solar Fire, an appropriate technology NGO in India, has developed an open source design for a small, manually operated, 12 kW peak Fresnel concentrator that generates temperatures up to and can be used for various thermal applications including steam powered electricity generation. The largest CSP systems using Compact linear Fresnel reflector technology is the 125 MW Reliance Areva CSP plant in India.Purohit, I. Purohit, P. 2017.

A limitation of high-concentrator (i.e. HCPV and HCPVT) systems is that they maintain their long-term advantages over conventional c-Si/mc-Si collectors only in regions that remain consistently free of atmospheric aerosol contaminants (e.g. light clouds, smog, etc.). Power production is rapidly degraded because 1) radiation is reflected and scattered outside of the small (often less than 1°-2°) acceptance angle of the collection optics, and 2) absorption of specific components of the solar spectrum causes one or more series junctions within the multi-junction cells to under-perform.

Home oxygen patient Raymond Joseph Bachmeier (82) was also killed in the incident. Authorities said that the fire was caused by "a cigarette being smoked in bed while on oxygen." Fayetteville, Arkansas, US. July 14, 2018 :An explosion at a house left a 69 year old man dead. The man's daughter reported that he had been smoking near his oxygen concentrator. Marion County, Indianapolis, US. May 19, 2018 :A man died in a fire which is believed to have started after he was smoking near an oxygen cylinder.

Flabeg AG - solar power mirror installations In contrast to the power tower concentrator concept that California's original Solar One project uses. The specially coated tubes, made of glass and steel, were designed and produced by Solel Solar Systems as well as by Schott Glass in Germany.Schott AG - special glass tubing Motion control was supplied by Parker Hannifin, from components by Ansco Machine Company. Solar thermal power plants designed for solar-only generation are well matched to summer noon peak loads in areas with significant cooling demands, such as the southwestern United States.

The Sable processing plant in Zambia was then used to extract copper metal and cobalt salt from the concentrate. Annual production capacity was estimated as 10,000 tonnes of copper cathode and 1,000 tonnes of cobalt carbonate. Phase two involved expanding the concentrator and building a new acid-leaching and SX-EW plant to produce copper and cobalt metal on site. In this phase, which used higher-grade copper ore from the Ruashi mine, capacity increased to 45,000 tonnes of copper cathode and about 3,500 tonnes of cobalt carbonate or metal.

The Crafton Hills College Solar Farm is a 1.61 MWp (1.30 MWAC) concentrator photovoltaics (CPV) power station in Yucaipa, California. It was built by Rosendin Electric using 140 dual-axis SF-1100S systems, each of which contains 28 SF-1100 modules. Each module contains reflective optics to concentrate sunlight 650 times onto multi-junction solar cells, allowing a greater efficiency than other photovoltaic power plants. The farm was constructed under California Solar Initiative (CSI) incentives and the projected annual output of 2.7 GW·h partially satisfies electricity consumption at the college.

The Falcon semi batch centrifugal concentrator is primarily used for the recovery of free (liberated) precious metals such as gold, silver and platinum. The machine generates forces up to 200 times the force of gravity (200 G's) and makes use of a two-stage rotating bowl for mineral separation. The smooth-walled lower portion is for particle stratification and then a fluidized upper portion is used for the collection of the heavier particles. The machine is stopped periodically to rinse and collect the valuable concentrate from the bowl.

The Falcon Ultra-Fine (UF) centrifugal concentrator is primarily used for the separation of heavy minerals which occur in ore concentrations above 0.1% by weight, such as cassiterite, tantalum and scheelite when the majority of the particles are smaller than 75 µm. The machine generates forces up to 600 times the force of gravity (600 G's) and uses a smooth-walled bowl for particle stratification with a pneumatically controlled rubber lip for heavy material collection. The machine is stopped periodically to rinse and collect the valuable concentrate from the bowl.Deveau, C (2006).

The University of Arizona CPV Array is a 2.38 MWp (2.0 MWAC) concentrator photovoltaics (CPV) power station in Tucson, Arizona. It consists of 34 Amonix 7700 systems constructed in the Solar Zone of the University of Arizona's Science and Technology Park (UASTP). It uses all three of the methods available to increase efficiency: dual-axis tracking, fresnel lens sunlight concentrators, and multi-junction cells. The annual electricity production is expected to be about 3.5 GW·h, and is being sold to Tucson Electric Power (TEP) under a 20-year power purchase agreement (PPA).

The Digital Local Exchange (DLE) hosts a number of concentrators and routes calls to different DLEs or DMSUs depending on the destination of the call. The heart of the DLE is the Digital Switching Subsystem (DSS) which consists of Time Switches and a Space Switch. Incoming traffic on the 30 channel PCM highways from the Concentrator Units is connected to Time Switches. The purpose of these is to take any incoming individual Time Slot and connect it to an outgoing Time Slot and so perform a switching and routing function.

Typhoon Dot over Hainan Island on June 10 Tropical Storm Dot produced widespread rainfall in the Philippines, leading to several landslides. In Toledo City, the Carmen copper Concentrator had to temporarily shut down after a landslide disrupted the facility's water supply. As a result, the Atlas Consolidated Mining and Development Corporation lost approximately 272,000 kg (600,000 lb) of copper. Across Hainan Island, the storm produced heavy rains and damaging winds that left eight cities without power or telephone service. Throughout Hainan, about 1,400 homes were destroyed and 60,000 more were damaged.

In the fixed telephone network, a node may be a public or private telephone exchange, a remote concentrator or a computer providing some intelligent network service. In cellular communication, switching points and databases such as the Base station controller, Home Location Register, Gateway GPRS Support Node (GGSN) and Serving GPRS Support Node (SGSN) are examples of nodes. Cellular network base stations are not considered to be nodes in this context. In cable television systems (CATV), this term has assumed a broader context and is generally associated with a fiber optic node.

A concentrator usually provides communication capability between many low-speed, usually asynchronous channels and one or more high-speed, usually synchronous channels. Usually different speeds, codes, and protocols can be accommodated on the low-speed side. The low-speed channels usually operate in contention and require buffering. # A device that connects a number of links with only one destination, the main function of this device is to make a kind of load balancing between two or more servers connected together, data distribution is done according to the server processing rate.

With the development of the product separator and changes to reduce the wear rate of the mill, the first two full-scale IsaMills were put into production in the Mount Isa lead–zinc concentrator in 1994. With 3000 liter ("L") volumes, they were six times larger than the largest standard mill previously produced by Netzsch. They had a motor size of 1120 kW and allowed the new design and grinding medium to be proven at a commercial scale.G Harbort, M Hourn and A Murphy, "IsaMill ultrafine grinding for a sulfide leach process," Australian Journal of Mining, 1998.

Magnetite mining operations would require the construction of a concentrator plant and either a rail link or magnetite slurry pipeline from Morawa to the port of Geraldton or to a new port to be built at Oakajee (north of Geraldton). Red River Resources hold tenements just 20 km south of Koolanooka at its Feral Prospect. They have currently identified 5 zones of iron enrichment in BIF ranging in strike length from 100m-500m. The Karara Mining joint venture between Gindalbie Metals and Chinese steel producer, Ansteel, has substantial holdings 85 kilometres (53 mi) east of Morawa.

However, this differs from, and should not be confused with concentrated solar power, the other large-scale solar generation technology, which uses heat to drive a variety of conventional generator systems. Both approaches have their own advantages and disadvantages, but to date, for a variety of reasons, photovoltaic technology has seen much wider use in the field. , concentrator systems represented about 3% of utility-scale solar power capacity. In some countries, the nameplate capacity of a photovoltaic power stations is rated in megawatt-peak (MWp), which refers to the solar array's theoretical maximum DC power output.

Checkweighers can be built with metal detectors, x-ray machines, open-flap detection, bar-code scanners, holographic scanners, temperature sensors, vision inspectors, timing screws to set the timing and spacing between product, indexing gates and concentrator ducts to line up the product into a designated area on the conveyor. An industrial motion checkweigher can sort products from a fraction of a gram to many, many kilograms. In English units, is this from less than 100th of an ounce to as much as 500 lbs or more. Specialized checkweighers can weigh commercial aircraft, and even find their center-of-gravity.

Solar Systems is a winner in the 2005 Engineering Excellence Awards. The Mildura Solar Concentrator Power Station project to build a solar plant was announced in 2006 and expected to be completed in 2013.Lawrence Bartlett: "World’s biggest solar plant for Australia" in Cosmons, 26 October 2006Chee Chee Leung: "Brumby planning to plug Victoria into the sun", in The Age, 17 June 2008 However, Solar Systems was placed under voluntary administration on 7 September 2009 placing the Mildura Solar Power Station project and the jobs of two-thirds of the workforce at risk. In 2011, Silex Systems purchased Solar Systems for $2 million.

Annual production capacity is estimated at 20,000 tonnes of copper metal and 8,000 tonnes of cobalt in cobalt hydroxide, with expansion to 110,000 tonnes of copper metal and 23,000 tonnes of cobalt in cobalt hydroxide by the first quarter of 2012. Facilities include a dense media separation concentrator and a hydrometallurgical plant for crushing, screening, milling, pre-leaching, leaching, clarification and SX/EW. In November 2011 Glencore confirmed that it should compete its expansion in December, bring up annual capacity to 110,000 metric tons of copper metal as planned. Glencore made an investment of $650 million to develop this capacity.

The 100 MW PV Mildura Solar Concentrator Power Station, formerly expected to be completed in 2017, is now cancelled.Tom Arup: "Sunraysia's huge solar farm up and running", in The Age, 17 July 2013 It was expected to be the biggest and most efficient solar photovoltaic power station in the world. The power station was expected to concentrate the sun by 500 times onto the solar cells for ultra high power output. The Victorian power station would have generated electricity directly from the sun to meet the annual needs of over 45,000 homes with on-going zero greenhouse gas emissions.

The first reef located was the Victoria and in 1884 it also provided the first stone for crushing which yielded of gold from of ore, which was carted some distance to the Soldier's Cap (Mount Freda) battery near Cloncurry for crushing. The Bower Bird Battery of five stamps, four berdans, and concentrator was probably erected in 1895, after being relocated from other places. The stamper was already over 20 years old, having been manufactured in 1873. Between 1895 and 1897 the field's main producer the Victoria reef officially produced of ore yielding of gold before being abandoned, possibly due to drought.

In the United States, Medicare switched from fee-for-service payment to a flat monthly rate for home oxygen therapy in the mid-1980s, causing the durable medical equipment (DME) industry to rapidly embrace concentrators as a way to control costs. This reimbursement change dramatically decreased the number of primary high pressure and liquid oxygen delivery systems in use in homes in the United States at that time. Oxygen concentrators became the preferred and most common means of delivering home oxygen. The number of manufacturers entering the oxygen concentrator market increased exponentially as a result of this change.

Theoretically, an infinite number of junctions would have a limiting efficiency of 86.8% under highly concentrated sunlight. Currently, the best lab examples of traditional crystalline silicon (c-Si) solar cells have efficiencies between 20% and 25%, while lab examples of multi-junction cells have demonstrated performance over 46% under concentrated sunlight."Solar Junction Breaks Concentrated Solar World Record with 43.5% Efficiency". Cnet.com."Sharp Hits Concentrator Solar Cell Efficiency Record, 43.5%" Commercial examples of tandem cells are widely available at 30% under one-sun illumination,"ZTJ Space Solar Cell" , emcore and improve to around 40% under concentrated sunlight.

The Snyder column is a wide glass tube divided into sections (usually 3 to 6) by horizontal glass partitions or constrictions. Each partition has a hole, into which seats a hollow glass bead with an inverted "teardrop" shape. Vigreux- like glass "fingers" limit the vertical motion of each bead.. These floating glass stoppers act as check valves, closing and opening with vapor flow, and enhancing vapor-condensate mixing. A Snyder colum can be used with a Kuderna- Danish concentrator to efficiently separate a low boiling extraction solvent such as methylene chloride from volatile but higher boiling extract components (e.g.

Concentrator photovoltaics technology established its presence in the solar industry during the period 2006 to 2015. The first HCPV power plant that exceeded 1 MW-level was commissioned in Spain in 2006. By the end of 2015, the number of CPV power plants (including both LCPV and HCPV) around the world accounted for a total installed capacity of 350 MW. Field data collected over six years is also starting to benchmark the prospects for long-term system reliability. The emerging CPV segment has comprised ~0.1% of the fast-growing utility market for PV installations over the decade up to 2017.

Currently, Borax Argentina's operations produce a variety of boron chemical products, including boric acid, borax decahydrate, borax pentahydrate, anhydrous borax and boroglas from concentrates and ulexite minerals carted from the mines and concentrators. In addition, the mine and concentrator at Sijes produce mineral concentrates for direct sale. On 1 July 2013 Orocobre announced the relocation of the borax chemical plant from its location in Campo Quijano (close to the city of Salta) to the Tincalayu mine site. The relocation of the borax chemical plant is said to have significant financial benefits for the company through a reduction of both operating and logistics cost.

Bay Networks was acquired by Northern Telecom in June 1998 for US$ 9.1 billion, broadening Nortel's reach from its traditional carrier customer base into enterprise data networking. Reflective of this expanded product set and market, Nortel renamed itself Nortel Networks after the merger. In December 2009, as part of its bankruptcy proceedings, Nortel sold its Enterprise Networking equipment and software business to Avaya. The sale included a few remaining Bay Networks products that were still active in Nortel's portfolio at the time of the sale, such as the Ethernet Switch 450 and Backbone Concentrator Node (BCN) router.

Approximately 6,300 tonnes of ore-grade material were transported daily via a conveyor system from the mine to surface where it was stored in a covered stockpile of approximately 12,000 tonnes live capacity prior to processing in the Concentrator plant. Following various process the concentrate was then trucked south to Cork for onward shipment to various customers. Until its closure, the mine was owned and operated by Vedanta Resources Zinc International, being acquired from Anglo American in 2011. In total, 22.4 million tonnes of ore were produced, at an average grade of 11.63% zinc, 1.96% lead and 26 ppm silver.

When the capsule hit the desert floor, these wafers shattered into over 10,000 pieces of material. The Genesis team, along with the efforts of the Air Force's Photographic and Engineering Technician team, set up a clean room at Dugway Proving Ground. NASA scientists spent months filtering through bent metal and shards of razor sharp material, each of the salvageable pieces of material going into its own small container where they were stored for a short time. Some weeks later, one of the lead scientists and the supervisor of the engineering technicians came upon what turned out to be the solar wind concentrator.

POCs operate on the same principle as a home concentrator, pressure swing adsorption. The basic set up of a POC is a miniaturized air compressor, a cylinder filled containing the sieve, a pressure equalizing reservoir and valves and tubes. During the first half of the first cycle the internal compressor forces this air through a system of chemical filters known as a molecular sieve. This filter is made up of silicate granules called zeolite which attract (via adsorption) nitrogen molecules onto their surfaces more strongly than they attract oxygen molecules – this takes the nitrogen out of the air and concentrates the oxygen.

With the advent of sophisticated electronics in the early part of the 1990s, telephone service providers developed methods to share a single copper line to transmit multiple telephone calls simultaneously. Various pair gain methods using time-division multiplexing and frequency-division multiplexing prevented interference between simultaneous calls. A distant suburb may have a subscriber loop carrier or digital loop carrier system in which a remote concentrator is located near the subscribers to connect multiple local subscriber loops to one common line to a central office exchange. A single optical fibre can also be shared between multiple subscribers in fibre to the cabinet systems.

A hybrid system combines (C)PV and CSP with one another or with other forms of generation such as diesel, wind and biogas. The combined form of generation may enable the system to modulate power output as a function of demand or at least reduce the fluctuating nature of solar power and the consumption of non-renewable fuel. Hybrid systems are most often found on islands. ; CPV/CSP system : A novel solar CPV/CSP hybrid system has been proposed, combining concentrator photovoltaics with the non-PV technology of concentrated solar power, or also known as concentrated solar thermal.Phys.

Afrimines Resources SPRL, based in Democratic Republic of the Congo, owns various mining resources. In May 2008 Tiger Resources announced that it had secured the rights to explore several new and highly prospective tenements in Katanga in partnership with Afrimines Resources and Katanga Minerals Holdings. Katanga Mining produces copper and cobalt at the Kamoto Mine, which also includes the Kamoto concentrator, the Luilu metallurgical plant, the Kamoto underground mine and two oxide open pit resources in the Kolwezi district. A joint venture of Katanga Mining (75%) and Gécamines (25%) began mining Tilwezembe, an open-pit copper and cobalt mine, in 2007.

The facility was constructed by Suncore and Bixby Electric starting in 2012 on a former landfill near EMCORE's corporate headquarters in the Sandia Science and Technology Park. Suncore Photovoltaics Technology Co, Ltd, was founded in 2010 as a joint-venture company by Chinese LED optoelectronics manufacturer San'an Optoelectronics Co, Ltd (60%) and U.S. semiconductor manufacturer EMCORE Corporation (40%). EMCORE was also purchasing part of the facility's output for its local administrative and manufacturing operations. The 1.21 MWp (1.0 MWAC) concentrator photovoltaics (CPV) portion of the facility consists of 48 dual-axis Suncore CPV-Gen3.5 solar tracking systems divided into 2 sections.

Situated some 80 km northeast of the capital, Santiago, the Andina mine was discovered in 1920 but production did not start until 1970. It consists of the Rio Blanco underground (block cave) mine and the Sur Sur open pit and an underground concentrator. Unlike other Codelco mines, it does not have its own smelter. Geologically it consists of about half the Los Bronces-Rio Blanco complex of mineralised breccias, the other half being owned and mined by the Los Bronces mine of Compania Minera Disputada de la Condes which is in turn owned by Anglo American.

Now the Sur Sur and Don Luis breccias above and to the south of the underground mine are being worked as open pits. Production in 2007 was 218,322 tonnes of extractable copper and 2,525 tonnes molybdenum in concentrate from the 72,000 tonnes per day concentrator. Work is now under way on the Andina Phase I Development Project which aims to raise mill capacity to 92,000 tonnes per day and is expected to be complete by November 2009. Pre feasibility studies on raising mill capacity to over 200,000 tonnes per day by 2014 should be complete this year.

Oxygen concentrators based upon pressure swing adsorption (PSA), VSA, or vacuum- pressure swing adsorption (VPSA) can be used to generate the oxygen if electricity is available. Stationary oxygen concentrators typically use PSA technology, which has performance degradations at the lower barometric pressures at high altitudes. One way to compensate for the performance degradation is to utilize a concentrator with more flow capacity. There are also portable oxygen concentrators that can be used on vehicular DC power or on internal batteries, and at least one system commercially available measures and compensates for the altitude effect on its performance up to .

A solution of 4% holmium oxide in 10% perchloric acid, permanently fused into a quartz cuvette as an optical calibration standard Holmium has the highest magnetic strength of any element, and therefore is used to create the strongest artificially generated magnetic fields, when placed within high-strength magnets as a magnetic pole piece (also called a magnetic flux concentrator). Since it can absorb nuclear fission-bred neutrons, it is also used as a burnable poison to regulate nuclear reactors. Holmium-doped yttrium iron garnet (YIG) and yttrium lithium fluoride (YLF) have applications in solid-state lasers, and Ho-YIG has applications in optical isolators and in microwave equipment (e.g., YIG spheres).

The Bingham Canyon Mine, more commonly known as Kennecott Copper Mine among locals, is an open-pit mining operation extracting a large porphyry copper deposit southwest of Salt Lake City, Utah, in the Oquirrh Mountains. The mine is the largest man-made excavation, and deepest open-pit mine in the world, which is considered to have produced more copper than any other mine in history – more than 19 million tons. The mine is owned by Rio Tinto Group, a British-Australian multinational corporation. The copper operations at Bingham Canyon Mine are managed through Kennecott Utah Copper Corporation which operates the mine, a concentrator plant, a smelter, and a refinery.

Roland Winston is a leading figure in the field of nonimaging optics and its applications to solar energy, and is sometimes termed the "father of non- imaging optics". He is the inventor of the compound parabolic concentrator(CPC), a breakthrough technology in solar energy. He is also a former Guggenheim Fellow, past head of the University of Chicago Department of Physics, a member of the founding faculty of University of California Merced, and as of 2013, head of the California Advanced Solar Technologies Institute. He holds more than 25 patents, chiefly related to solar energy, and has been figuratively said to have a "patent on the sun".

Gas cylinders containing oxygen to be used at home. When in use a pipe is attached to the cylinder's regulator and then to a mask that fits over the person's nose and mouth. A home oxygen concentrator for a person with emphysema Oxygen can be separated by a number of methods, including chemical reaction and fractional distillation, and then either used immediately or stored for future use. The main types of sources for oxygen therapy are: #Liquid storage – Liquid oxygen is stored in chilled tanks until required, and then allowed to boil (at a temperature of 90.188 K (−182.96 °C)) to release oxygen as a gas.

The Hemerdon Tungsten and Tin Project is Wolf Minerals core asset. It is located near the Plymouth in the County of Devon, in the southwest of the UK. Wolf has identified the Hemerdon project as a potential major new source of global tungsten supply. It acquired the project in December 2007 and has conducted extensive exploration programs and established a large JORC Resource inventory and completed a successful Definitive Feasibility Study, in 2011. The DFS identified Hemerdon as a highly economic potential producer of low cost tungsten, and was based on a two-stage open pit with an initial 10 year life, and a 3Mtpa concentrator with associated infrastructure.

3 seats, 4 masks), in case someone has an infant in their lap, or someone in the aisle needs to grab one. An oxygen mask consists of a yellow, soft, silicone facial cup with white elastic bands for securing the mask to the passenger's face. This band is adjustable by pulling two ends looped through the facial cup. The mask may also have a concentrator or re-breather bag that may or may not inflate depending on the cabin altitude, which has (in some instances) made passengers nervous the mask was not providing adequate oxygen, causing some to remove them, who thereby suffered hypoxia.

Toquepala is expanding its concentrator capacity in order to increase annual production by 100,000 tonnes of copper and 3,100 tonnes of molybdenum at a total capital cost of approximately $US1.2 billion. Environmental Impact Assessment (EIA) studies for plant concentration and tailings deposit expansion were recently approved by Peruvian Ministry of Energy and Mining according to directorial resolution Nº611-2014-MEM/DGAAM given on 17 December 2014. This year, Geoservice Ingeniería and Walsh received mandates from Southern Copper Corporation, while the former is executing studies on surface, underground water resources and hydraulic infrastructure, the latest was in charge of executing the Environmental Impact Assessment studies for plant concentration and tailings deposit expansions.

After the town became a hub of gold and silver mining, Basin's population peaked at about 1,500 in the first decade of the 20th century but gradually declined as the mines were depleted. Abandoned mining equipment, closed or barricaded mine portals, and the ruins of a smelter and ore concentrator remain in Basin in the 21st century. Historic buildings from Basin's heyday form much of the core of the CDP's small business district, which includes a fire station, a post office, two restaurants, a bar, a commercial gallery, and small specialty shops. Basin has a small elementary school, its own water system, and a low-power radio station.

The Hatch Solar Energy Center is a 5.88 MWp (5.0 MWAC) concentrator photovoltaics power station, the largest in North America when it was completed in 2011. It was built by Blattner Energy using 84 dual-axis Amonix 7700 panels each of which contains 7,560 fresnel lens to concentrate sunlight 500 times onto multijunction photovoltaic cells, allowing a greater efficiency than other photovoltaic power plants. It uses all three of the methods available to increase efficiency - dual-axis tracking, concentrating photovoltaics, and multijunction cells. The systems are certified for operation for 50 years, but the multijunction cells may need to be replaced in 25 years.

In the US, these "mild personal hyperbaric chambers" are categorized by the FDA as CLASS II medical devices and requires a prescription in order to purchase one or take treatments. The most common option (but not approved by FDA) some patients choose is to acquire an oxygen concentrator which typically delivers 85–96% oxygen as the breathing gas. Oxygen is never fed directly into soft chambers but is rather introduced via a line and mask directly to the patient. FDA approved oxygen concentrators for human consumption in confined areas used for HBOT are regularly monitored for purity (+/- 1%) and flow (10 to 15 liters per minute outflow pressure).

The outer extremities of the concentrate bowl house a series of ribs and between each pair of ribs is a groove. During operation the lighter material flows upward over the grooves and heavy mineral particles (usually of economic value) become trapped within them. Pressurized water is injected through a series of tangential water inlets along the perimeter of each groove to maintain a fluidized bed of particles in which heavy mineral particles can be efficiently concentrated. The Knelson concentrator typically operates as a batch process, with lighter gangue material being continuously discharged via overflow and a heavy mineral concentrate periodically removed by flushing the bowl with water.

The base station controller (BSC) provides, classically, the intelligence behind the BTSs. Typically a BSC has tens or even hundreds of BTSs under its control. The BSC handles allocation of radio channels, receives measurements from the mobile phones, and controls handovers from BTS to BTS (except in the case of an inter-BSC handover in which case control is in part the responsibility of the anchor MSC). A key function of the BSC is to act as a concentrator where many different low capacity connections to BTSs (with relatively low utilisation) become reduced to a smaller number of connections towards the mobile switching center (MSC) (with a high level of utilisation).

Hendy stamp mill, mid 1800s By the 1890s, the Joshua Hendy Iron Works was a leader in the mining industry, supplying equipment to mining companies globally, including ore carts, ore crushers, stamp and ball mills and other equipment. Many of the engineering innovations developed by Hendy became mining industry standards, employed as late as the 1970s, such as the hydraulic giant monitor, the tangential water wheel, the Hendy ore concentrator, the Challenge ore feeder, and the Hendy hydraulic gravel elevator. Hendy giant hydraulic crushers were used to excavate the Panama Canal. After Joshua Hendy died in 1891, management of the company was taken over by his nephews Samuel and John.

Oil-based products are typically avoided at this stage as they add weight and greasiness and can burn on the hair. Next, hair is blow dried straight in small sections at high heat, using a round brush to create tension and volume. A concentrator nozzle is attached to the end of the blow dryer to allow heat to be directed on the section being straightened. After blow drying, a small amount of serum is applied and hair is wrapped in a dubi or doobie, a method which wraps and pins the hair around the head, using it as a giant roller, to create additional straightening and movement.

The project covers near the intersection of highways IH 37 and U.S. 181.Texas' Largest Solar Project Breaks Ground In San Antonio (April 15, 2010), CPS Energy. It has 214,500 solar photovoltaic modules manufactured by US firm First Solar that are mounted onto fixed-tilt (20deg) racks. The plant is expected to produce more than 26 GWh of electricity per year.The Blue Wing Solar Project: “Truly Utility-Scale” The installation also includes a 500-kilowatt demonstration facility where a variety of other thin film and crystalline silicon PV modules, as well as a concentrator photovoltaic (CPV) unit, have been installed for evaluation and comparison purposes.

These devices were initially called remote concentrators or simply remotes. In fibre-optic distribution systems which offer triple-play services (voice, television, internet) the digitization has arrived at the customer premises and signals are digitized at the source and combined using customer edge routers. This traffic enters the distribution network at an Optical Network Termination and is carried to the central office using Wavelength division multiplexing and Passive optical networking. In telecommunication, the term concentrator has the following meanings: # In data transmission, a functional unit that permits a common path to handle more data sources than there are channels currently available within the path.

A mediated VPN is a virtual private network topology where two or more participants connect to a central switchboard server managed typically by a third party in order to create a virtual private network between them, as distinct from a typical VPN arrangement whereby clients of an organisation connect to a VPN concentrator managed by the same organization. Typically a switchboard server (referred to as a mediator) will manage several VPNs, identifying each individually by authentication credentials (such as username, network name and passwords). The mediator's role is to assign IP addresses to each participant in a VPN, and to encrypt data through the switchboard server in order to keep it secure from other participants in other VPNs.

By increasing the concentration of oxygen in the air, the effects of lower barometric pressure are countered and the level of arterial p is restored toward normal capacity. A small amount of supplemental oxygen reduces the equivalent altitude in climate-controlled rooms. At 4000 m, raising the oxygen concentration level by 5 percent via an oxygen concentrator and an existing ventilation system provides an altitude equivalent of 3000 m, which is much more tolerable for the increasing number of low-landers who work in high altitude. In a study of astronomers working in Chile at 5050 m, oxygen concentrators increased the level of oxygen concentration by almost 30 percent (that is, from 21 percent to 27 percent).

Optical path length (OPL) is constant between wavefronts. When applied to nonimaging optics, this result extends the string method to optics with both refractive and reflective surfaces. Figure "DTIRC" (Dielectric Total Internal Reflection Concentrator) on the left shows one such example. DTIRC The shape of the top surface s is prescribed, for example, as a circle. Then the lateral wall m1 is calculated by the condition of constant optical path length S=d1+n d2+n d3 where d1 is the distance between incoming wavefront w1 and point P on the top surface s, d2 is the distance between P and Q and d3 the distance between Q and outgoing wavefront w2, which is circular and centered at R1.

The tracker and module support structure for a modern HCPV system must each remain accurate within 0.1°-0.3° in order to keep the solar resource adequately centered within the acceptance angle of the receiver collection optics, and thus concentrated onto the PV cells. This is a challenging requirement for any mechanical system that is subjected to the stresses of varying movements and loads. Ignacio Luque‐Heredia, Pedro Magalhães, and Matthew Muller, Chapter 6: CPV Tracking and Trackers. In: Handbook of Concentrator Photovoltaic Technology, C. Algora and I. Rey-Stolle editors, 2016, Pages 293-333, , Economical procedures for periodic realignment and maintenance of the tracker may thus be required to preserve system performance over its expected lifetime.

This standard and command system provides not only for smart meters and related data but also for general purpose extension to other smart grid devices. A project of EDF, France includes demand management, street lighting control, remote metering and billing, customer specific tariff optimisation, contract management, expense estimation and gas applications safety. There are also many specialised niche applications which use the mains supply within the home as a convenient data link for telemetry. For example, in the UK and Europe a TV audience monitoring system uses powerline communications as a convenient data path between devices that monitor TV viewing activity in different rooms in a home and a data concentrator which is connected to a telephone modem.

The plant occupies 82 acres of a 160 acre parcel of land adjacent to Highway 17 and existing transmission infrastructure near the community of Mosca. It was originally constructed as three units to evaluate and demonstrate three types of photovoltaic (PV) technology at utility-scale, including: 1) fixed-tilt, seasonally-adjustable, flat-panel PV; 2) single-axis-tracking, flat-panel PV; and 3) dual-axis- tracking, concentrator photovoltaics (CPV). The first two units account for about 6.8 MW of the plant capacity and use 2,224 and 24,384 Suntech polycrystalline silicon panels, respectively. The third unit accounts for the remaining ~1.2 MW and consists of 72 SOLON Mover tracker systems with concentrating solar panels.

Satellite image of the 550-megawatt Topaz Solar Farm in California, US Global map of global horizontal irradiation. At the end of 2019, global installed solar capacity was 586 GW. Solar energy, radiant light and heat from the sun, is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, concentrated solar power (CSP), concentrator photovoltaics (CPV), solar architecture and artificial photosynthesis. Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert, and distribute solar energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.

CPV modules on dual axis solar trackers in Golmud, China Concentrator photovoltaics (CPV) systems employ sunlight concentrated onto photovoltaic surfaces for the purpose of electrical power production. Contrary to conventional photovoltaic systems, it uses lenses and curved mirrors to focus sunlight onto small, but highly efficient, multi- junction solar cells. Solar concentrators of all varieties may be used, and these are often mounted on a solar tracker in order to keep the focal point upon the cell as the sun moves across the sky.MSU-CSET Participation Archive with notation in the Murray Ledger & Times Luminescent solar concentrators (when combined with a PV-solar cell) can also be regarded as a CPV system.

Univac Buffer Processor Maintenance Panel The Univac Buffer Processor (BP) was used in several real-time computer system installations in the 1960s as a network concentrator and front end system to the UNIVAC 418 and UNIVAC 490/494 real-time systems. A notable set of installations was at British European Airways in London (the BEACON Online Reservations system). The initial reservations system at B.E.A. comprised over 200 agent sets in London, connected to the Univac 490 via a network of eight Univac Buffer Processors. Subsequently, in 1966, the B.E.A. reservations network was expanded to include agents in offices in Manchester, Birmingham, Glasgow, Bristol and Edinburgh and later to B.E.A. offices in selected cities on the European continent.

Large scale mining began in 1903 with the completion of a concentrator that had a 200 ton capacity which was funded by Grant B. Schley. The Britannia Mining and Smelting Company, a branch of the Howe Sound Company, finally commenced mining in the early 1900s, and owned the site for the next sixty years. The first ore was shipped to the Crofton Smelter on Vancouver Island in 1904, and the mine achieved full production in 1905. A town had grown up around the mine and a post office opened on January 1, 1907 where it was named after the nearby mine. In 1912 John Wedderburn Dunbar Moodie was authorized to upgrade the operation and increase production from the mine.

Strictly speaking, in Unices a terminal device comprises the underlying tty device driver, responsible for the physical control of the device hardware via I/O instructions and handling device interrupt requests for character input and output, and the line discipline. A line discipline is independent of the actual device hardware, and the same line discipline can be used for a terminal concentrator device responsible for multiple controlling terminals as for a pseudoterminal. In fact, the line discipline (or, in the case of BSD, AIX, and other systems, line disciplines) are the same across all terminal devices. It is the line discipline that is responsible for local echo, line editing, processing of input modes, processing of output modes, and character mapping.

At the Dell Interop 2012 in Las Vegas Dell announced the first FTOS based blade- switch: the Force10 MXL 10/40Gpbs blade switch, and later a 10/40Gbit/s concentrator. The FTOS MXL 40 Gb was introduced on 19 July 2012.Dell community website: Dell announces F10 MXL switch, 24 April 2012. Visited 18 May 2012 The MXL provides 32 internal 10Gbit/s links (2 ports per blade in the chassis), two QSFP+ 40Gbit/s ports and two empty expansion slots allowing a maximum of 4 additional QSFP+ 40Gbit/s ports or 8 10Gbit/s ports. Each QSFP+ port can be used for a 40Gbit/s switch to switch (stack) uplink or, with a break-out cable, 4 x 10Gbit/s links.

In October 2010, through the Terrane acquisition, Thompson Creek Metals obtained the Mount Milligan development project and initiated construction soon after. On August 15, 2013, the initial feed to the concentrator started the operation of the mine. By September 2013, the mine had its first production, a copper-gold concentrate. Mount Milligan Mine reached commercial production as of February 18, 2014, which means that the mill operated at 60% planned capacity throughput for 30 days. Industrious activities were sustained through 2014 and are consistent today. The Company predicts that it will reach 60,000 tpd on a steady basis once it installs a secondary crushing circuit. Thompson Creek Metals expects to reach approximately 60,000 tpd by the end of 2015 by utilizing temporary crushing.

The narrator, Arthur Wright, and his friend Hugh Dutton visit their former classmate, Dr. John Pollard at his combination house/laboratory. Pollard, a classic mad scientist, has been conducting research into the question of what causes the mutations that drive evolution. Pollard informs them that he has determined that cosmic rays are the source of the mutations, and that he has decided that bombarding himself with heavy concentrations of cosmic rays will cause him to evolve into a future version of humanity. Pollard has built himself a cosmic-ray-concentrator that will allow him to evolve at the rate of 50 million years every 15 minutes exposure, but he needs someone else to operate it, which is why he has invited Wright and Dutton to his laboratory.

Dawn's 10 kW triple-junction gallium arsenide solar array at full extension Multi-junction cells consist of multiple thin films, each essentially a solar cell grown on top of another, typically using metalorganic vapour phase epitaxy. Each layer has a different band gap energy to allow it to absorb electromagnetic radiation over a different portion of the spectrum. Multi-junction cells were originally developed for special applications such as satellites and space exploration, but are now used increasingly in terrestrial concentrator photovoltaics (CPV), an emerging technology that uses lenses and curved mirrors to concentrate sunlight onto small, highly efficient multi-junction solar cells. By concentrating sunlight up to a thousand times, High concentrated photovoltaics (HCPV) has the potential to outcompete conventional solar PV in the future.

A 32-port serial console server A console server (console access server, console management server, serial concentrator, or serial console server) is a device or service that provides access to the system console of a computing device via networking technologies. Most commonly, a console server provides a number of serial ports, which are then connected to the serial ports of other equipment, such as servers, routers or switches. The consoles of the connected devices can then be accessed by connecting to the console server over a serial link such as a modem, or over a network with terminal emulator software such as telnet or ssh, maintaining survivable connectivity that allows remote users to log in the various consoles without being physically nearby.

As a result, it may be possible that this technology could be readily scaled up to megawatt range by multiplying the available reactor units and by connecting the plant to heliostat fields (fields of sun-tracking mirrors) of a suitable size. Material constraints due to the required high temperatures are reduced by the design of a membrane reactor with simultaneous extraction of hydrogen and oxygen that exploits a defined thermal gradient and the fast diffusion of hydrogen. With concentrated sunlight as heat source and only water in the reaction chamber, the produced gases are very clean with the only possible contaminant being water. A "Solar Water Cracker" with a concentrator of about 100 m² can produce almost one kilogram of hydrogen per sunshine hour.

Originally owned by the American Cerro De Pasco Corporation, who brought the mine to production, it has been gradually built up by Codelco and is now the subject of a major expansion scheme. At the end of 2007, reserves and resources in the mining plan totalled 5,698 million tonnes grading 0.78% copper containing 44.3 million tonnes of metal and additional identified resources of 11,342 tonnes grading 0.52% copper containing 59.6 million tonnes of metal. The orebodies are at considerable heights, between 3,000 and 4,200 metres and operations can be severely affected by the weather. Originally the mine was only the underground block cave and an underground concentrator with an "hotel" (bunkhouse) where the workers live when the Rio Blanco valley is impassable in the winter.

In 2017, Norilsk Nickel announced that it had invested $14 billion in a major development program aimed at reducing sulfur dioxide emissions in Norilsk by 75% by 2023, compared to 2015 as a base year. One of the bigger steps taken to combat pollution was the closure of Nornickel's old smelter in Norilsk, the main source of SO2 emissions within the city boundaries since 1942. Norilsk Nickel has stated that the total emissions of its Russian operations was 6% lower in 2016 than in 2015, primarily due to the shutdown of the smelter. The company's environmental program also includes an upgrade of the Talnakh Concentrator, to increase sulfur disposal to tailings, and the construction of recycling units to extract sulfur dioxide from waste gases at Nadezhda Metallurgical Plant and Copper Plant.

AXE10 covers two main types of digital telephony switching equipment: the remote subscriber switch (RSS) and the AXE10 local switch. RSS acts as a remote concentrator and deals with the conversion of analogue telephony signals used in the access network, which is the copper pairs between exchange buildings and customer premises, also called local loop, and the multiplexing of customer lines over cabling to the AXE10 local switching unit. The AXE10 local switch uses a processor-controlled switch to route calls and data depending on the destination of the telephony transmission. BT's AXE10 network, which has been in service since 1986,"Digital Switching", Connected Earth, accessed 2009-05-17 is maintained in house by its own engineers although Ericsson still provide high-level support, software upgrades and repairs at component level.

According to the Tasnim news agency, Southwest Asia’s largest factory producing face masks in Iran was opened by Mohammad Mokhber, director of the Headquarters for Execution of Imam Khomeini’s Order in April 2020. The factory is able to "produce 4 million masks per month". According to the report of EIKO's officials, the EIKO has provided several medical facilities to fight with the coronavirus pandemic in Iran, including " 25 million three-layered and N95 masks, launching a production line of medical masks, production of Iranian test kit for coronavirus infection, research on the medicine of the disease, launching the 4030 phone line with the help of 2,200 doctors and paramedics for answering people’s questions about coronavirus, making oxygen concentrator (with producing 50 machines every day), production of 400,000 liters of disinfectant gel".

Rio Tinto is the majority shareholder in the venture, with 58.7% of the joint stock as of October 2013.FP: "Rio Tinto to complete Iron Ore Company of Canada expansion by mid-2014" 15 Oct 2013 Mitsubishi controlled 26.2% of the investment as of March 2013.G+M: "Dented by aluminum, Rio Tinto aims to unload Iron Ore Co" 1 Mar 2013 Based in Montreal, Quebec, IOC currently has mining and concentrator operations in Labrador City, and operates the Quebec North Shore and Labrador Railway to ship ore concentrate from the mines, such as Wabush, to the port of Sept-Îles, Quebec. Currently, this railway (along with the TSH, CFAQ, and WABL lines) form an isolated railroad network, as it does not interchange with any other rail lines on the North American network.

As the strike continued into late July, Elizabeth Gurley Flynn—a well-known American labor organizer—spoke to strikers and encouraged them to persevere, but many soon returned to work in August, effectively ending the strike. As natural ore reserves diminished due to increased production for the World War I effort, Oliver turned to ore that required more processing than the rich ore that he originally purchased from the Merritt brothers. While the Trout Lake Concentrator was still in operation in the Canisteo District, Oliver built the Pilotac and Extaca plants near the city of Virginia. Pilotac was built to research methods for concentrating taconite ore, and Extaca was built to agglomerate, or combine, taconite concentrate into a high-iron product that could be used in steel mills.

In fall 2006, the gender studies program merged with the concentration in Sexuality and Society to form the Gender and Sexuality Studies Program. Gender and Sexuality Studies is an interdisciplinary concentration that examines the construction of gender and sexuality in social, cultural, political, economic, or scientific contexts. Each concentrator will focus on a well-defined topic or question and work closely with a concentration advisor to develop a program that investigates this focus area rigorously and supplements it with foundational courses in the relevant disciplines. Typical areas of focus might include the acculturation of gender, sexuality and race in American politics or activism; the construction of sexual and gendered identities in educational institutions or in various forms of visual media; a contrast between different cultural understandings of sexual identity, a particular national literature and history.

The British developed System X (telephony), and other smaller systems also emerged in the early 1980s. Some digital switches, notably the 5ESS and very early versions of Ericsson AXE 10, continued to use analog concentrator stages, using SPC-like technologies, rather than direct connections to the digital line cards containing the CODEC. Early in the 21st century the industry began using a 5th generation of telephony switching, as TDM and specialist hardware based digital circuit switching is being replaced by softswitches and voice over IP VoIP technologies. The principle feature of stored program control is one or multiple digital processing units (stored-program computers) that execute a set of computer instructions (program) stored in the memory of the system by which telephone connections are established, maintained, and terminated in associated electronic circuitry.

WCP B at Namalope Kenmare employees at Mineral Separation Plant stockpiles in Mozambique The Company's principal asset is the Moma Titanium Minerals Mine, located in Moma, Nampula Province, Mozambique. It has been in production since late 2007.Proactive Investors, 17 March 2010 In 2019 the Mine produced 892,900 tonnes of ilmenite (plus associated co-products) and this is expected to increase to 1.2 million tonnes per annum once the third of the Company’s three growth projects, the relocation of Wet Concentrator Plant (WCP) B, is complete.Kenmare Resources Annual Report 2019: Published 30th March 2020: Page 8 and 9 The mine produces 7% of the world's titanium feedstocks (ilmenite and rutile), which are predominantly used in the production of titanium dioxide pigment favoured for its whiteness and opacity in paper, paint and plastics.

Reorganized as the Seattle & International Railway in 1896 (incorporated June 30, 1896(), the line leased the portion of the locally-legendary Everett and Monte Cristo Railway that ran from Everett east to Snohomish.Monte Cristo, Washington (gif); Dr. David Cameron, "The Greatest Gold Rush of the Cascades", Monte Cristo Preservation Association; Mt.

The Northern Pacific acquired control February, 1898, succeeded the Seattle & International in 1901. The Northern Pacific operated the SLS&E; from 15 March 1892 to 1 July 1893, when it was purchased by a reorganized SLS&E; as the Seattle & International Railroad and Spokane & Seattle Railroad,Pleasants is ambiguous about the purchase date.

NASA Integrated Symmetrical Concentrator SPS concept Space-based solar power (SBSP) is the concept of collecting solar power in outer space and distributing it to Earth. Potential advantages of collecting solar energy in space include a higher collection rate and a longer collection period due to the lack of a diffusing atmosphere, and the possibility of placing a solar collector in an orbiting location where there is no night. A considerable fraction of incoming solar energy (55–60%) is lost on its way through the Earth's atmosphere by the effects of reflection and absorption. Space-based solar power systems convert sunlight to microwaves outside the atmosphere, avoiding these losses and the downtime due to the Earth's rotation, but at great cost due to the expense of launching material into orbit.

When the cell output was equalized, the baffle and the tube would be pointing at the sun. This was sufficient to enable the array to track the sun’s azimuth and generate considerable heat, as reported in tests published in the ASHRAE Journal, which noted that ". . . the array of collectors . . .follow the sun from just after sunrise to just before sunset and often results in the collection of twice as many usable BTUs of energy at a higher temperature than provided by high quality flat plate collectors.".ASHRAE Journal, November 1976 "Evaluating a Solar Energy Concentrator" Dr. Richard L. Pendleton Popular Science Magazine Illustration, 1976 These arrays proved popular – and were used to drive absorption refrigeration equipment on large commercial installations at Trinity University in San Antonio, Texas, at Frenchman’s Reef Hotel in St Thomas, USVI, residences,Solar Engineering January 1976, pp.

Also, in the case of secondary mirrors use, similar to the ones found in Cassegrain telescopes, would be prone to heat damage by partially concentrated sunlight from primary mirror. In order to remove the above restrictions, V.P. Vasylyev proposed to apply an alternative design of a mirrored collector – the ring-array concentrator. This type of collector has an underside lens-like position of its focal area that avoids shadowing of the collector by the target and minimizes the risk of its coating by ejected debris. Provided the sunlight concentration ~ 5 × 103 times, a surface irradiance of around 4-5 MW/m2 leads to a thrusting effect ~ 103 N. Intensive ablation of the rotating asteroid surface under the focal spot will lead to the appearance of a deep "canyon", which can contribute to the formation of the escaping gas flow into a jet-like one.

Magma Arizona Railroad in Superior, 1967 The origin of Magma Mine began on 22 March 1875, when Charles G. Mason and four companions found native silver, and staked the Silver King claim. On 29 March 1875, the Silver Queen (Magma) vein was staked, and the Silver Queen Mining Company was organized in 1880. However, with the depletion of silver, the Silver Queen King shut down in 1893, and the Silver King in 1896. In 1910, William Boyce Thompson and George Gunn bought the Silver Queen mine, and organized the Magma Copper Company. A 300-ton-per-day concentrator was built in 1914. In 1915, a narrow-gauge railway connected Superior with the Southern Pacific Railroad, which was converted to standard gauge in 1923. A smelter was built in 1924. After 71 years of production, the Magma mine closed in August 1982 due to high operating costs and declining copper prices.

Mount Milligan — Mount Milligan Mine (open-pit copper and gold mine) is located 90 miles northwest of Prince George in Central British Columbia, Canada. Mount Milligan Mine has a concentrator with a 60,000 tpd design capacity copper flotation processing plant. The estimated life of Mount Milligan Mine is approximately 24 years (which is based on spot metal prices copper and gold). Over the life of the mine, it is estimated that it will produce an average annual of 85 million pounds of copper and 186,700 ounces of gold in 155,000 tonnes of concentrate. In 2015 through 2019, the average annual production is projected to increase at approximately 94 million pounds of copper and 285,800 ounces of gold in 165,000 tonnes of concentrate. Thompson Creek Metals Company filed an updated NI 43-101 Technical Report for Mount Milligan Mine on January 21, 2015 that confirms these projections.

W. Evans, 1981, The Days of May, Rigby Publishers Ltd., Adelaide, pp 190,199. For a young business finding it difficult to gain the trust of Australian farmers who preferred importing machinery from larger more established companies in the USA and Britain,M. W. Evans, 1981, The Days of May, Rigby Publishers Ltd., Adelaide, pp 205. the success of the exhibit was a great advertisement. May Brothers Damp Weather Thresher and Reaper, as featured in the "Australasian Implement & Housing Furnishing Co. Catalogue 1916–17" The May Brothers Patent Compound Jigger was another breakthrough invention for the firm, although one that took the mining community – who were hesitant about the new company – some convincing. The jigger, a concentrator that treated ore on the surface, was unveiled shortly after the Jubilee Exhibit in 1887, and an order from the Umberrumberka mine in New South Wales arrived within months.

There is a series of conveyors that take ore to the Copperton concentrator and flotation plant. The longest conveyor is long. As of 2010, Kennecott Utah Copper was the second largest copper producer in the US, and provided about 13-18% percent of the U.S.'s copper needs. It is one of the top producing copper mines in the world with production at more than 18.7 million short tons (16.7 million long tons; 17.0 Mt). Every year, Kennecott produces approximately 300 thousand short tons (272 kt or 268 thousand long tons) of copper, along with 400 thousand troy ounces (13.7 short tons 12.4 tonnes, or 12.2 long tons) of gold, 4 million troy ounces (124 tonnes, 137 short tons or 122 long tons) of silver, about 10 thousand short tons (9,100 tonnes or 8,900 long tons) of molybdenum, and about a million short tons (910 kt or 890 thousand long tons) of sulfuric acid, a by- product of the smelting process.

Concentrating solar power (CSP), also known as solar thermal electricity (STE), uses arrays of mirrors that concentrate the sun’s rays to temperatures between 4000C and 10000C. Electrical power is produced when the concentrated light is converted to heat, which drives a heat engine (usually a steam turbine) connected to an electrical power generator. A CSP system consists of: 1) a concentrator or collector containing mirrors that reflect solar radiation and deliver it to the receiver; 2) a receiver that absorbs concentrated sunlight and transfers heat energy to a working fluid (usually a mineral oil, or more rarely, molten salts, metals, steam or air); 3) a transport and storage system that passes the fluid from the receiver to the power conversion system; and 4) a steam turbine that converts thermal power to electricity on demand. Copper is used in field power cables, grounding networks, and motors for tracking and pumping fluids, as well as in the main generator and high voltage transformers.

Neon lamps have been historically used as microwave and millimeter-wave detectors ("plasma diodes" or glow discharge detectors (GDDs)) up to about 100 GHz or so and in such service were said to exhibit comparable sensitivity (of the order of a few 10s to perhaps 100 microvolts) to the familiar 1N23-type catwhisker- contacted silicon diodes once ubiquitous in microwave equipment. More recently it has been found that these lamps work well as detectors even at sub- millimeter ("terahertz") frequencies and they have been successfully used as pixels in several experimental imaging arrays at these wavelengths. In these applications the lamps are operated either in "starvation" mode (to reduce lamp-current noise) or in normal glow discharge mode; some literature references their use as detectors of radiation up into the optical regime when operated in abnormal glow mode. Coupling of microwaves into the plasma may be in free space, in waveguide, by means of a parabolic concentrator (e.g.

MTS can and does use communication controllers such as the IBM 2703 and the Memorex 1270 to support dial-in terminals and remote batch stations over dial- in and dedicated data circuits, but these controllers proved to be fairly inflexible and unsatisfactory for connecting large numbers of diverse terminals and later personal computers running terminal emulation software at ever higher data rates. Most MTS sites choose to build their own front-end processors or to use a front-end processor developed by one of the other MTS sites to provide terminal support. These front-end processors, usually DEC PDP-8, PDP-11, or LSI-11 based with locally developed custom hardware and software, would act as IBM control units attached to the IBM input/output channels on one side and to modems and phone lines on the other. At the University of Michigan the front-end processor was known as the Data Concentrator (DC).

SunPower's high-efficiency solar cell technology was originally developed to meet the more rigorous demands of LCPV, despite having a much greater success in the flat-panel PV market in the U.S. In late 2011, SunPower announced that its C7 technology could reduce the levelized cost of electricity relative to competing 'utility-scale' PV installations available at the time by 20%. In a strategic effort to achieve cost reductions at manufacturing scale - reductions similar to those rapidly being realized by commoditized PV using less efficient technology - SunPower entered a joint venture (JV) with the Chinese firm Tianjin Zhonghuan Semiconductor (TZS) to ramp-up LCPV production in late 2012. In early 2014, SunPower announced the supply of 70 MW of "concentrator cell assemblies" to the JV's first 50 MW production line in Inner Mongolia for the first of two projects totaling 120 MW to be completed by the end of 2015. During the early 2015 completion of its Fort Churchill facility in the U.S., Apple announced its funding of another 40 MW of the JV's LCPV projects in China to support of its growing operations there with renewable energy.

This program is expected to increase Buenavista's production capacity from 180,000 tons of copper per year to over 450,000 tons. During 2Q11, Buenavista reached its full capacity and produced 45,588 tons of copper: 15,170 tons of copper cathode at its SX/EW Plant and 30,417 tons of copper concentrate at the Concentrator Plant. Cananea is among the world's largest copper mines in terms of reserves. A miners strike at the Buenavista del Cobre mine lasted almost three years, until broken on the night of June 6, 2010, when Mexican police dispersed striking workers. On June 6, 2011, the Confederation of Mexican Workers (“CTM”) was granted the collective bargaining agreement for the Buenavista union, replacing the miner's National Union of Mining and Metallurgical Workers Sindicate, Section No.65 (Labor Union), headed by Napoleón Gómez Urrutia, People celebrate these days of mining copper in a festival in Cananea in the town square called "La Feria De Cobre" (translates to "The Copper Festival" The second and smaller active copper mine is "Minera Maria", owned by Minera Frisco, S.A.B. de C.V. a Mexican company controlled by Carlos Slim Helú and family, including Inmobiliaria Carso, S.A. de C.V. and located west of Cananea.

The 8.5 kg Mini- 11 and 25 kg Mini-12 can produce resolution mass spectra up to m/z 600, a range that makes it useful for studying metabolites, lipids, and other small molecules. The group also developed and incorporated a digital microfluidic platform to the MMS with the application to extract and quantify drugs in urine. Mini 12 can perform MS5 and analyze directly such complex samples as whole blood, untreated food, and environmental samples, without sample preparation or chromatographic separation. Miniature mass spectrometer systems 1st Detect introduced the MMS 1000 which is a cylindrical ion-trap mass spectrometer with MS/MS capability. Some characteristics are advertised as wide mass range (35-450 Da), high resolution (<0.5 Da FWHM), fast analysis time (>=0.5s). The inlet flow rate can be high – up to 600ml/min with no external pumps or carrier gases. The MMS 1000 is incorporated with a non- cryogenic pre-concentrator. This coupling enhances the sensitivity up to 10^5 with a fast speed of 30s. 1st Detect's miniaturized mass spectrometers are used in a range of applications, including homeland security, military, breath analysis, leak detection, environmental and industrial quality control. The MMS 1000 was originally designed for NASA, for the purpose of monitoring air quality on the International Space Station.
