Humphrey Pump
The Humphrey pump is a large internal combustion gas-fueled liquid piston pump. The pump was invented by H. A. Humphrey and first presented in paper 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. A small number of pumps were built between 1906 and 1925 for use in large-scale water supply projects. Although only a few pumps were built, some continued in service into the 1960s. Operation Humphrey's pump consists of a large U-shaped tube, filled with water. One end is sealed by a heavy cast iron, or steel, 'combustion head'. The combustion head contains the inlet and exhaust valves, the ignition source and withstands the pressure of the combustion chamber. Water enters the pump through sprung inlet valves below the combustion chamber. A distinctive feature of the Humphrey pump, ...

Coal Gas
Coal gas is a flammable gaseous fuel made from coal and supplied to the user via a piped distribution system. It is produced when coal is heated strongly in the absence of air. Town gas is a more general term referring to manufactured gaseous fuels produced for sale to consumers and municipalities. The original coal gas was produced by the coal gasification reaction, and the burnable component consisted of a mixture of carbon monoxide and hydrogen in roughly equal quantities by volume. Thus, coal gas is highly toxicity, toxic. Other compositions contain additional Calorific Value, calorific gases such as methane, produced by the Fischer–Tropsch process, and volatile hydrocarbons together with small quantities of non-calorific gases such as carbon dioxide and nitrogen. Prior to the development of natural gas supply and transmission—during the 1940s and 1950s in the United States and during the late 1960s and 1970s in the United Kingdom and Australia—almost all gas for fu ...

Del Rio, Texas
Del Rio (in Spanish language, Spanish, ''Del Río'', "from the river") is a city in and the county seat of Val Verde County, Texas, Val Verde County in southwestern Texas, United States. As of 2020 United States census, 2020, Del Rio had a population of 34,673. History The Spanish established a small settlement south of the Rio Grande in present-day Mexico, and some Spanish colonists settled on the north side of the Rio Grande as early as the 18th century. The United States acquired the territory following the Mexican War and, after the American Civil War, Paula Losoya Taylor in 1862 was the first Anglo-American to build a ''hacienda '' in the area. San Felipe Springs, about east of the Rio Grande on the U.S. side of the border, has historically produced of water a day. This was critical to the arid region. Developers acquired several thousand acres of land adjacent to the springs, and to San Felipe Creek formed by the springs, from the state of Texas in exchange for build ...

Engineering Heritage Award
The Engineering Heritage Awards, formally known as the ''Engineering Heritage Hallmark Scheme'', were established by the Institution of Mechanical Engineers (IMechE) in 1984 to identify and promote artefacts, locations, collections and landmarks of significant engineering importance. Development of the Awards Engineering Heritage Hallmark Scheme (EHHS) In 1984, IMechE launched its Engineering Heritage Hallmark Scheme. For an object or artefact etc. to be considered for an award, an IMechE member would be required to complete a nomination form and submit it to the Institution. Upon submission, two referees would be appointed, one nominated by the Regional Committee where the object is located and a second independent referee. The submissions from both referees would then be reviewed by the Institution's Technical Support department before a decision was taken on the application. Engineering Heritage Awards (EHA) In 2007, the Institution established the Heritage Committee to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Boveri
Brown, Boveri & Cie. (Brown, Boveri & Company; BBC) was a Swiss group of electrical engineering companies. It was founded in Baden bei Zürich, in 1891 by Charles Eugene Lancelot Brown and Walter Boveri who worked at the Maschinenfabrik Oerlikon. In 1988 BBC 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's early activities included manufacturin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dry Dock
A dry dock (sometimes drydock or dry-dock) is a narrow basin or vessel that can be flooded to allow a load to be floated in, then drained to allow that load to come to rest on a dry platform. Dry docks are used for the construction, maintenance, and repair of ships, boats, and other watercraft. History China The use of dry docks in China goes at least as far back as the 10th century A.D. In 1088, Song dynasty scientist and statesman Shen Kuo (1031–1095) wrote in his '' Dream Pool Essays'': Europe Greco-Roman world The Greek author Athenaeus of Naucratis (V 204c-d) reports something that may have been a dry dock in Ptolemaic Egypt in the reign of Ptolemy IV Philopator (221-204 BC) on the occasion of the launch of the enormous '' Tessarakonteres'' rowing ship. However a more recent survey by Goodchild and Forbes does not substantiate its existence. It has been calculated that a dock for a vessel of such a size might have had a volume of 750,000 gallons of water. Renaiss ...

Renmark, SA
Renmark is a town in South Australia's rural Riverland area, and is located northeast of Adelaide, on the banks of the River Murray. The Sturt Highway between Adelaide and Sydney runs through the town; Renmark is the last major town encountered in South Australia when driving this route. It is a few kilometers west of the SA–Victoria and SA–NSW borders. It is above sea level. History It has been suggested that the name Renmark refers to a local Aboriginal word meaning "red mud" (the original inhabitants of the area were the Erawirung people). However, the mud at Renmark is not red. Alternatively, it could be derived from the name Bookmark, later Calperum, the station founded by the Chambers brothers, from which was excised for the town and irrigation project. Another possibility is the name of an early settler in the district, William Renny. Wool was shipped from "Renmark" in 1878, The first unambiguous use of the name (as "Renmark Flat") in newspapers was in Novem ...
