Humphrey Pump
The Humphrey pump is a large internal combustion gas-fuelled liquid-piston pump. They were used for large-scale water supply projects. They were only popular for a short time, from around 1910 to the outbreak of World War I, but they continued in service for a long period afterwards, some lasting into the 1970s. The pump was invented by H. A. Humphrey, MIMechE. It was described in a paper presented by him to the Institution of Mechanical Engineers on 19 November 1909. A pump capable of pumping 250,000 gallons per hour to a head of 35 feet was exhibited at the 1910 Brussels Exhibition, where it was awarded two ''Grands Prix'', for both engines and pumps. Operation The pumps are an internal-combustion fluidyne engine. Although fluidynes are now considered to be a form of the external combustion Stirling engine, the Humphrey pump was an early example of one using internal combustion. A fluidyne has few moving parts: although they may include various valves, their key feature is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Four-stroke
A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed: #Intake: Also known as induction or suction. This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). In this stroke the intake valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing vacuum pressure into the cylinder through its downward motion. The piston is moving down as air is being sucked in by the downward motion against the piston. #Compression: This stroke begins at B.D.C, or just at the end of the suction stroke, and ends at T.D.C. In this stroke the piston compresses the air-fuel mixture in preparation for ignition during the power stroke (below). Both the intake and exhaust valves are close ...

Brown Boveri
Brown, Boveri & Cie. (Brown, Boveri & Company; BBC) was a Swiss group of electrical engineering companies. It was founded in Zürich, in 1891 by Charles Eugene Lancelot Brown and Walter Boveri who worked at the Maschinenfabrik Oerlikon. In 1970 BBC took over the Maschinenfabrik Oerlikon. In 1988 it merged with ASEA to form ABB. Early History of BBC Brown Boveri BBC Brown Boveri was established in 1891. The company was one of only a few multinational corporations to operate subsidiaries that were larger than the parent company. Because of the limitations of the Swiss domestic market, Brown Boveri established subsidiaries throughout Europe relatively early in its history, and at times had difficulty maintaining managerial control over some of its larger operating units. The merger with ASEA, a company which was praised for its strong management, was expected to help Brown Boveri reorganize and reassert control over its vast international network. Activity in Britain Brown Boveri' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''The Engineer'' is a London-based monthly magazine and website covering the latest developments and business news in engineering and technology in the UK and internationally. History and description ''The Engineer'' was founded in January 1856. It was established by Edward Charles Healey, an entrepreneur and engineering enthusiast with financial interests in the railways whose friends included Robert Stephenson and Isambard Kingdom Brunel. The journal was created as a technical magazine for engineers. ''The Engineer'' began covering engineering including inventions and patents during a high point of British economic manufacturing power. In the 19th century it also published stock prices of raw materials. Together with the contemporary ''Engineering'' journal the work is considered a valuable historical resource for the study of British economic history.

King George V Reservoir Pumping Station1
King is the title given to a male monarch in a variety of contexts. The female equivalent is queen, which title is also given to the consort of a king. *In the context of prehistory, antiquity and contemporary indigenous peoples, the title may refer to tribal kingship. Germanic kingship is cognate with Indo-European traditions of tribal rulership (c.f. Indic ''rājan'', Gothic ''reiks'', and Old Irish ''rí'', etc.). *In the context of classical antiquity, king may translate in Latin as '' rex'' and in Greek as '' archon'' or '' basileus''. *In classical European feudalism, the title of ''king'' as the ruler of a ''kingdom'' is understood to be the highest rank in the feudal order, potentially subject, at least nominally, only to an emperor (harking back to the client kings of the Roman Republic and Roman Empire). *In a modern context, the title may refer to the ruler of one of a number of modern monarchies (either absolute or constitutional). The title of ''king'' is us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon Monoxide
Carbon monoxide (chemical formula CO) is a colorless, poisonous, odorless, tasteless, flammable gas that is slightly less dense than air. Carbon monoxide consists of one carbon atom and one oxygen atom connected by a triple bond. It is the simplest molecule of the oxocarbon family. In coordination complexes the carbon monoxide ligand is called carbonyl. It is a key ingredient in many processes in industrial chemistry. The most common source of carbon monoxide is the partial combustion of carbon-containing compounds, when insufficient oxygen or heat is present to produce carbon dioxide. There are also numerous environmental and biological sources that generate and emit a significant amount of carbon monoxide. It is important in the production of many compounds, including drugs, fragrances, and fuels. Upon emission into the atmosphere, carbon monoxide affects several processes that contribute to climate change. Carbon monoxide has important biological roles across phylogenetic ...
