Westinghouse Electric (1886)
The Westinghouse Electric Corporation was an American manufacturing company founded in 1886 by George Westinghouse.

Propeller (marine)
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the blade to the water at t ...

Turbo Generator
A turbo generator is an electric generator connected to the shaft of a steam turbine or gas turbine for the generation of electric power. Large steam-powered turbo generators provide the majority of the world's electricity and are also used by steam-powered turbo-electric ships. Small turbo-generators driven by gas turbines are often used as auxiliary power units (APU, mainly for aircraft). History The first turbo-generators were electric generators powered by water turbines. The first Hungarian water turbine was designed by the engineers of the Ganz Works in 1866; industrial-scale production with dynamo generators started only in 1883. Engineer Charles Algernon Parsons demonstrated a DC steam-powered turbo generator using a dynamo in 1887, and by 1901 had supplied the first large industrial AC turbo generator of megawatt power to a plant in Eberfeld, Germany. Turbo generators were also used on steam locomotives as a power source for coach lighting and water pumps for heat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herbert Hoover Presidential Library And Museum
The Herbert Hoover Presidential Library and Museum is the presidential library and burial place of Herbert Clark Hoover, the 31st president of the United States (1929–1933), located on the grounds of the Herbert Hoover National Historic Site in West Branch, Iowa. The library is one of thirteen presidential libraries run by the National Archives and Records Administration. In 1954, a group of Hoover's friends incorporated the Herbert Hoover Birthplace Foundation to raise money for the preservation of his birthplace and the area around it, and to plan for improvements to the site. One of their ideas was to build a small museum, and with Hoover's approval work began in the late 1950s. The architectural firm of Eggers and Higgins of New York drew the plans for the original building, a modest limestone structure of just over 4,000 square feet. While the museum at West Branch was still under construction, Hoover decided to expand it and to make it his Presidential Library. Th ...

Typhoon
A typhoon is a mature tropical cyclone that develops between 180° and 100°E in the Northern Hemisphere. This region is referred to as the Northwestern Pacific Basin, and is the most active tropical cyclone basin on Earth, accounting for almost one-third of the world's annual tropical cyclones. For organizational purposes, the northern Pacific Ocean is divided into three regions: the eastern (North America to 140°W), central (140°W to 180°), and western (180° to 100°E). The Regional Specialized Meteorological Center (RSMC) for tropical cyclone forecasts is in Japan, with other tropical cyclone warning centers for the northwest Pacific in Hawaii (the Joint Typhoon Warning Center), the Philippines, and Hong Kong. Although the RSMC names each system, the main name list itself is coordinated among 18 countries that have territories threatened by typhoons each year. Within most of the northwestern Pacific, there are no official typhoon seasons as tropical cyclones form thr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vanuatu
Vanuatu ( or ; ), officially the Republic of Vanuatu (french: link=no, République de Vanuatu; bi, Ripablik blong Vanuatu), is an island country located in the South Pacific Ocean. The archipelago, which is of volcanic origin, is east of northern Australia, northeast of New Caledonia, east of New Guinea, southeast of the Solomon Islands, and west of Fiji. Vanuatu was first inhabited by Melanesian people. The first Europeans to visit the islands were a Spanish expedition led by Portuguese navigator Fernandes de Queirós, who arrived on the largest island, Espíritu Santo, in 1606. Queirós claimed the archipelago for Spain, as part of the colonial Spanish East Indies, and named it . In the 1880s, France and the United Kingdom claimed parts of the archipelago, and in 1906, they agreed on a framework for jointly managing the archipelago as the New Hebrides through an Anglo-French condominium. An independence movement arose in the 1970s, and the Republic of Vanuatu was fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Espiritu Santo Naval Base
Naval Advance Base Espiritu Santo or Naval Base Espiritu Santo, most often just called ''Espiritu Santo'', was a major advance Naval base that the U.S. Navy Seabees built during World War II to support the Allied effort in the Pacific. The base was located on the island of Espiritu Santo in the New Hebrides, now Vanuatu, in the South Pacific. The base also supported the U.S. Army and Army Air Corps, U.S. Coast Guard, and US Marine Corps. It was the first large advance base built in the Pacific. By the end of the war it had become the second-largest base in the theater. To keep ships tactically available there was a demand for bases that could repair and resupply the fleet at advance locations, rather than return them to the United States. Prior to December 7th, Pearl Harbor was the U.S. fleet's largest advance base in the Pacific. Espiritu became capable of all aspects necessary to support the Fleet's operations from fleet logistics in fuel, food, and ammunition, to transport ...

New Hebrides
New Hebrides, officially the New Hebrides Condominium (french: link=no, Condominium des Nouvelles-Hébrides, "Condominium of the New Hebrides") and named after the Hebrides Scottish archipelago, was the colonial name for the island group in the South Pacific Ocean that is now Vanuatu. Native people had inhabited the islands for three thousand years before the first Europeans arrived in 1606 from a Spanish expedition led by Portuguese navigator Pedro Fernandes de Queirós. The islands were colonised by both the British and French in the 18th century, shortly after Captain James Cook visited. The two countries eventually signed an agreement making the islands an Anglo-French condominium that divided New Hebrides into two separate communities: one Anglophone and one Francophone. That divide continued even after independence, with schools teaching in either one language or the other, and with different political parties. The condominium lasted from 1906 until 1980, when New He ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
