Krupp
The Krupp family (see pronunciation), a prominent 400-year-old German dynasty from Essen, is notable for its production of steel, artillery, ammunition and other armaments. The family business, known as Friedrich Krupp AG (Friedrich Krupp AG Hoesch-Krupp after acquiring Hoesch AG in 1991 and lasting until 1999), was the largest company in Europe at the beginning of the 20th century, and was the premier weapons manufacturer for Germany in both world wars. Starting from the Thirty Years' War until the end of the Second World War, it produced battleships, U-boats, tanks, howitzers, guns, utilities, and hundreds of other commodities. The dynasty began in 1587 when trader Arndt Krupp moved to Essen and joined the merchants' guild. He bought and sold real estate, and became one of the city's richest men. His descendants produced small guns during the Thirty Years' War and eventually acquired fulling mills, coal mines and an iron forge. During the Napoleonic Wars, Friedrich Kr ...

Revolutions Per Minute
Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or with the notation min−1) is a unit of rotational speed or rotational frequency for rotating machines. Standards ISO 80000-3:2019 defines a unit of rotation as the dimensionless unit equal to 1, which it refers to as a revolution, but does not define the revolution as a unit. It defines a unit of rotational frequency equal to s−1. The superseded standard ISO 80000-3:2006 did however state with reference to the unit name 'one', symbol '1', that "The special name revolution, symbol r, for this unit is widely used in specifications on rotating machines." The International System of Units (SI) does not recognize rpm as a unit, and defines the unit of frequency, Hz, as equal to s−1. :\begin 1~&\text &&=& 60~&\text \\ \frac~&\text &&=& 1~&\text \end A corresponding but distinct quantity for describing rotation is angular velocity, for which the SI unit is the ra ...

Société Anonyme Des Ateliers De Sécheron
The (SAAS, in English translated as ''"Anonymous Society of Sécheron Workshops"'') was a joint-stock company based in Geneva, Switzerland. It specialized in electrical engineering, including the manufacture of electrical equipment and locomotives. In 1989, the company was split into four successor companies, ABB Sécheron SA, ABB Power Generation (closed in 1995), ABB Systèmes de Transport and Sécheron SA. History In 1879, Alfred de Meuron set up a small workshop in Geneva to manufacture electrical appliances. This workshop ultimately formed the basis for the establishment of SAAS on 9 July 1918. The following year, 1919, Brown Boveri & Cie (BBC) became SAAS's main shareholder. Five years later, SAAS resumed its independence. The company remained independent until 1969, when competitive pressures forced it to seek new partners. In 1970, BBC took over as sole shareholder. However, the company's name was changed only in 1982, when it became BBC Sécheron SA. In 1988, B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Sulzer Diesel Engines
This article covers the History of Sulzer diesel engines from 1898 to 1997. Sulzer Brothers foundry was established in Winterthur, Switzerland, in 1834 by Johann Jakob Sulzer-Neuffert and his two sons, Johann Jakob and Salomon. Products included cast iron, firefighting pumps and textile machinery. Rudolf Diesel was educated in Augsburg and Munich and his works training was with Sulzer, and his later co-operation with Sulzer led to the construction of the first Sulzer diesel engine in 1898. In 2015, the Sulzer company lives on but it no longer manufactures diesel engines, having sold the diesel engine business to Wärtsilä in 1997. Overview Sulzer built diesel engines for stationary, road, rail and marine use. The engine types usually comprise a number, then some letters, then another number. For example, 6LDA28 indicates a six-cylinder engine in the "LDA" series with a 28 cm cylinder bore. Road In 1937, Sulzer introduced an opposed piston two-stroke diesel engine for road ...

Cyrillic Script
The Cyrillic script ( ), Slavonic script or the Slavic script, is a writing system used for various languages across Eurasia. It is the designated national script in various Slavic languages, Slavic, Turkic languages, Turkic, Mongolic languages, Mongolic, Uralic languages, Uralic, Caucasian languages, Caucasian and Iranian languages, Iranic-speaking countries in Southeastern Europe, Eastern Europe, the Caucasus, Central Asia, North Asia, and East Asia. , around 250 million people in Eurasia use Cyrillic as the official script for their national languages, with Russia accounting for about half of them. With the accession of Bulgaria to the European Union on 1 January 2007, Cyrillic became the third official script of the European Union, following the Latin script, Latin and Greek alphabet, Greek alphabets. The Early Cyrillic alphabet was developed during the 9th century AD at the Preslav Literary School in the First Bulgarian Empire during the reign of tsar Simeon I of Bulgar ...

Diesel-electric Locomotive
A diesel locomotive is a type of railway locomotive in which the prime mover (locomotive), prime mover is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. Early internal combustion engine, internal combustion locomotives and railcars used kerosene and gasoline as their fuel. Rudolf Diesel patented his first compression-ignition engine in 1898, and steady improvements to the design of diesel engines reduced their physical size and improved their power-to-weight ratios to a point where one could be mounted in a locomotive. Internal combustion engines only operate efficiently within a limited power band, and while low power gasoline engines could be coupled to mechanical transmission (mechanics), transmissions, the more powerful diesel engines required the development of new forms of transmission. This is because clutches would need to be very large at these power le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Straight-eight Engine
The straight-eight engine (also referred to as an inline-eight engine; abbreviated I8 or L8) is a piston engine with eight cylinders arranged in a straight line along the crankshaft. The number of cylinders and perfect primary and secondary engine balance resulted in smooth running, however there are several downsides relating to the significant length of the engine. Straight-eight engines were popular in luxury cars and racing cars in the 1920s to 1940s. During the 1950s, straight-eight engines were largely replaced by the more compact V8 engine design. Design A straight-eight can achieve perfect primary balance and secondary balance if an appropriate firing order is used. Like most other engines, torsional vibration of the crankshaft requires that a harmonic damper is installed on the crankshaft. at the accessory end of the crankshaft. As per other engines with 8 cylinders, the power delivery is smoother than engines with fewer cylinders. In the early 20th century, these sm ...

Railway Locomotives Introduced In 1933
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer faciliti ...
