Linke-Hofmann-Busch
Alstom Transport Deutschland, formerly Linke-Hofmann-Busch, is a German manufacturing company originally established in Breslau (now Wrocław, Poland) to produce locomotives and rolling stock. Its origins lay in the wheelwright business of Gottfried Linke, begun in 1834. After World War II, the company was reestablished in Salzgitter in West Germany. In 1994, GEC Alsthom acquired a 51% shareholding.World Update ''Railway Age'', August 1994, p. 88. It is now part of Alstom; the name Linke-Hofmann-Busch ceased to be used in 2009 when it became Alstom Transport Deutschland GmbH. Aircraft industry During World War I, it became one of many companies in Germany drawn into the aircraft industry even though they had no prior experience in aircraft design. Linke-Hofmann-Busch first entered the aircraft industry by repairing and constructing aircraft designed by other established companies under licence, such as the Roland C.IIa, Albatros B.IIa, C.III and C.X. In 1916 Linke-Hofmann-B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyester
Polyester is a category of polymers that contain the ester functional group in every repeat unit of their main chain. As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET). Polyesters include naturally occurring chemicals, such as in plants and insects, as well as synthetics such as polybutyrate. Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not. Synthetic polyesters are used extensively in clothing. Polyester fibers are sometimes spun together with natural fibers to produce a cloth with blended properties. Cotton-polyester blends can be strong, wrinkle- and tear-resistant, and reduce shrinking. Synthetic fibers using polyester have high water, wind and environmental resistance compared to plant-derived fibers. They are less fire-resistant and can melt when ignited. Liquid crystalline polyesters are among the first industrially used liquid crystal polymers. They are used for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rust
Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture. Rust consists of hydrous iron(III) oxides (Fe2O3·nH2O) and iron(III) oxide-hydroxide (FeO(OH), Fe(OH)3), and is typically associated with the corrosion of refined iron. Given sufficient time, any iron mass, in the presence of water and oxygen, could eventually convert entirely to rust. Surface rust is commonly flaky and friable, and provides no passivational protection to the underlying iron, unlike the formation of patina on copper surfaces. ''Rusting'' is the common term for corrosion of elemental iron and its alloys such as steel. Many other metals undergo similar corrosion, but the resulting oxides are not commonly called "rust". Several forms of rust are distinguishable both visually and by spectroscopy, and form under different circumstances. Other forms of rust include the result of reactions between iron and chlo ...

Großhansdorf (Hamburg U-Bahn Station)
Großhansdorf is a municipality in the district of Stormarn, in Schleswig-Holstein, Germany. It is situated approximately 3 km east of Ahrensburg, and 25 km northeast of Hamburg. History Großhansdorf was first mentioned in 1274 in a deed of Hamburg's St. Catherine's Church congregation, to which Großhansdorf was affiliated at that time. In 1435 the city of Hamburg acquired Großhansdorf and administered it as part of its forest villages domain (Walddörfer), consisting of a series of Hamburgian exclaves surrounded by then else Holstein territories. In 1642 the erection of a water mill is recorded, which operated until the 19th century. Since 1701 Großhansdorf was the seat of a ''forest rider'' (german: Waldreiter), an official of Hamburg's police administration, which is recalled in today's coat-of-arms of Großhansdorf. Hamburg then formed a free imperial city within the Holy Roman Empire. By 1806 the rotation of arable fields among the resident farming families ...

Hamburg Hauptbahnhof
Hamburg Hauptbahnhof (abbrev. ''Hamburg Hbf'') is the main railway station of the city of Hamburg, Germany. Opened in 1906 to replace four separate terminal stations, today Hamburg Hauptbahnhof is operated by DB Station&Service AG. With an average of 550,000 passengers a day, it is Germany's busiest railway station and the second-busiest in Europe after the Gare du Nord in Paris. It is classed by Deutsche Bahn as a category 1 railway station. The station is a through station with island platforms and is one of Germany's major transportation hubs, connecting long-distance Intercity Express routes to the city's U-Bahn and S-Bahn rapid transit networks. It is centrally located in Hamburg in the Hamburg-Mitte borough. The ''Wandelhalle'' shopping centre occupies the north side of the station building. History Before today's central station was opened, Hamburg had several smaller stations located around the city centre. The first railway line ( between Hamburg and Bergedorf) wa ...

Wheel Slide Protection
Wheel slide protection and wheel slip protection are railway terms used to describe automatic systems used to detect and prevent wheel-slide during braking or wheel-slip during acceleration. This is analogous to ABS and traction control systems used on motor vehicles. It is particularly important in slippery rail conditions. Sanding Sanding is one method of reducing wheel slip or slide. Locomotives and Multiple units have sandboxes which can deliver dry sand to the rails in front of the wheels. This may be initiated automatically when the Wheel Slide Protection system senses loss of adhesion, or the driver can operate it manually. Sanding may be connected to a computer system that determines the train's direction and where the sand should be applied: either forward or aft of the trucks. In older locomotives there was a manual lever attached to a valve that had three positions: Off, Forward, and Aft. Automatic control systems Wheel Slide Protection (WSP) equipment is generall ...

Quill Drive
A quill is a writing tool made from a moulted flight feather (preferably a primary wing-feather) of a large bird. Quills were used for writing with ink before the invention of the dip pen, the metal- nibbed pen, the fountain pen, and, eventually, the ballpoint pen. As with the earlier reed pen (and later dip pen), a quill has no internal ink reservoir and therefore needs to periodically be dipped into an inkwell during writing. The hand-cut goose quill is rarely used as a calligraphy tool anymore because many papers are now derived from wood pulp and would quickly wear a quill down. However, it is still the tool of choice for a few scribes who have noted that quills provide an unmatched sharp stroke as well as greater flexibility than a steel pen. Description The shaft of a flight feather is long and hollow, making it an obvious candidate for being crafted into a pen. The process of making a quill from a feather involves curing the shaft to harden it, then fashioning its tip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hamburg U-Bahn Type DT2
The Type DT2 is a two-car electric multiple unit (EMU) train type operated by the Hamburger Hochbahn AG on the Hamburg U-Bahn until 2015. They replaced the Type T and Type TU. Technical specifications The first trains had a ''Bo'1+1 Bo axle layout, with later trains built to an articulated design, formed as two-car sets. Up to four sets can be coupled together to form a long train. The car body was constructed using lightweight steel, based on a design licensed from the American Budd Company. They are equipped with Kiepe-build quill drives. Interior Seating arrangement consists of seating bays in a 2+2 layout. File:DT2-E Hamburg Innenraum.JPG, Interior of a refurbished "DT2E" unit History A total of 186 sets were delivered in five batches between 1962 and 1966. They were withdrawn after farewell runs through the entire network on November 28, 2015. Refurbishment Some sets underwent refurbishment from 1985 to 1987, which included replacement of the old cab ends and additi ...

Articulated Car
Articulated cars are rail vehicles which consist of a number of cars which are semi-permanently attached to each other and share common Jacobs bogies or axles and/or have car elements without axles suspended by the neighbouring car elements. They are much longer than single passenger cars. Because of the difficulty and cost of separating each car from the next, they are operated as a single unit, often called a ''trainset''. Passenger cars Articulated passenger cars are becoming increasingly common in Europe and the US. The passageways between the car elements are permanently attached. There is a safety benefit claimed that if the train derails, it is less likely to jackknife and modern construction techniques prevent telescoping. Articulated cars are not, however, a new idea. Many railways in Britain during the first half of the 20th century frequently rebuilt older, shorter cars into articulated sets, and the Great Northern Railway in Britain built suburban car sets ne ...

Linienzugbeeinflussung
Linienzugbeeinflussung (or LZB) is a cab signalling and train protection system used on selected German and Austrian railway lines as well as on the AVE and some commuter rail lines in Spain. The system was mandatory where trains were allowed to exceed speeds of in Germany and in Spain. It is also used on some slower railway and urban rapid transit lines to increase capacity. The German Linienzugbeeinflussung translates to ''continuous train control'', literally: ''linear train influencing''. It is also called ''linienförmige Zugbeeinflussung''. LZB is deprecated and will be replaced with European Train Control System (ETCS) between 2023 and 2030. It is referenced by European Union Agency for Railways (ERA) as a Class B ''train protection system'' in ''National Train Control'' (NTC). Driving cars mostly have to replace classical control logic to ETCS ''Onboard Units'' (OBU) with common '' Driver Machine Interface'' (DMI). Because high performance trains are often not scrap ...

Brown Boveri & Cie
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.
