Körting Hannover
Körting Hannover AG (previously Körting Brothers AG) is a long-standing industrial engineering company in Hanover. At the end of the 19th and beginning of the 20th century, the company played a leading role in the development of steam injectors in Germany and Europe. Körting still produces pump and pump-based vacuum technology, but also industrial burners and machinery related to thermal and chemical purification/transformation processes. History The Körting Brothers company was founded in Hanover on 1 November 1871 by the brothers Berthold and Ernst Körting. The brothers rented a small office and small space in the backyard of the present day 13 Joachimstrasse near Hanover Central Station. Berthold took charge of the commercial side, while Ernst specialized in the technical side. The brothers started successfully with the development and patenting of one of the first functioning injectors. In the beginning, only two workmen were employed. Due to the ever-increasing ord ...

Aktiengesellschaft
(; abbreviated AG, ) is a German word for a corporation limited by Share (finance), share ownership (i.e. one which is owned by its shareholders) whose shares may be traded on a stock market. The term is used in Germany, Austria, Switzerland (where it is equivalent to a ''S.A. (corporation), société anonyme'' or a ''società per azioni''), and South Tyrol for companies incorporated there. It is also used in Luxembourg (as lb, Aktiëgesellschaft, label=none, ), although the equivalent French language term ''S.A. (corporation), société anonyme'' is more common. In the United Kingdom, the equivalent term is public limited company, "PLC" and in the United States while the terms Incorporation (business), "incorporated" or "corporation" are typically used, technically the more precise equivalent term is "joint-stock company" (though note for the British term only a minority of public limited companies have their shares listed on stock exchanges).

Gas Engine
A gas engine is an internal combustion engine that runs on a gaseous fuel, such as coal gas, producer gas, biogas, landfill gas or natural gas. In the United Kingdom, the term is unambiguous. In the United States, due to the widespread use of "gas" as an abbreviation for gasoline (petrol), such an engine might also be called a gaseous-fueled engine or natural gas engine or spark ignited. Generally in modern usage, the term ''gas engine'' refers to a heavy-duty industrial engine capable of running continuously at full load for periods approaching a high fraction of 8,760 hours per year, unlike a gasoline automobile engine, which is lightweight, high-revving and typically runs for no more than 4,000 hours in its entire life. Typical power ranges from to . History Lenoir There were many experiments with gas engines in the 19th century, but the first practical gas-fuelled internal combustion engine was built by the Belgian engineer Étienne Lenoir in 1860. However, the L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engineering Companies Of Germany
Engineering is the use of scientific principles to design and build machines, structures, and other items, including bridges, tunnels, roads, vehicles, and buildings. The discipline of engineering encompasses a broad range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied mathematics, applied science, and types of application. See glossary of engineering. The term ''engineering'' is derived from the Latin ''ingenium'', meaning "cleverness" and ''ingeniare'', meaning "to contrive, devise". Definition The American Engineers' Council for Professional Development (ECPD, the predecessor of ABET) has defined "engineering" as: The creative application of scientific principles to design or develop structures, machines, apparatus, or manufacturing processes, or works utilizing them singly or in combination; or to construct or operate the same with full cognizance of their design; or to forecast their behavior under specific ...

Manufacturing Companies Based In Hanover
Manufacturing is the creation or production of goods with the help of equipment, labor, machines, tools, and chemical or biological processing or formulation. It is the essence of secondary sector of the economy. The term may refer to a range of human activity, from handicraft to high-tech, but it is most commonly applied to industrial design, in which raw materials from the primary sector are transformed into finished goods on a large scale. Such goods may be sold to other manufacturers for the production of other more complex products (such as aircraft, household appliances, furniture, sports equipment or automobiles), or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers). Manufacturing engineering is the field of engineering that designs and optimizes the manufacturing process, or the steps through which raw materials are transformed into a final product. T ...

V8 Engine
A V8 engine is an eight-cylinder piston engine in which two banks of four cylinders share a common crankshaft and are arranged in a V configuration. The first V8 engine was produced by the French Antoinette company in 1904, developed and used in cars and speedboats but primarily aircraft; while the American 1914–1935 ''Cadillac L-Head'' engine is considered the first road going V8 engine to be mass produced in significant quantities. The popularity of V8 engines in cars was greatly increased following the 1932 introduction of the ''Ford Flathead V8''. In the early 21st century, use of V8 engines in passenger vehicles declined as automobile manufacturers opted for more fuel efficient, lower capacity engines, or hybrid and electric drivetrains. Design V-angle The majority of V8 engines use a V-angle (the angle between the two banks of cylinders) of 90 degrees. This angle results in good engine balance, which results in low vibrations; however, the downside is a larg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gross-Basenach
Gross-Basenach or Groß-Basenach is the designation for a series of five so-called M-class German military semi-rigid airships constructed by balloonist Nikolaus Basenach and Major Hans Georg Friedrich Groß (1860–1924) of the Royal Prussian Airship Battalion Nr 2#Lui, Luisenstadt 2008 between 1907 and 1914. They produced one experimental and four military Groß-Basenach types, rebuilding each one several times. In all they were not as successful as Major Groß wished. He was one of the sharpest critics of the Zeppelin airships, but the overall superiority and popularity of the Zeppelins doomed his own airships. Even his more successful competitors, Parseval airships, Parseval and Schütte-Lanz, could not compete with Zeppelin after the war's end. Versuchsluftschiff The ''Versuchluftschiff'' (experimental airship) had a volume of 1,800 cubic metres and had a keel directly under the balloon envelope. It was mostly constructed by the firm Siemens-Schuckert GmbH.#pilot, Pilot und ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Approximation
An approximation is anything that is intentionally similar but not exactly equality (mathematics), equal to something else. Etymology and usage The word ''approximation'' is derived from Latin ''approximatus'', from ''proximus'' meaning ''very near'' and the prefix ''ad-'' (''ad-'' before ''p'' becomes ap- by assimilation (phonology), assimilation) meaning ''to''. Words like ''approximate'', ''approximately'' and ''approximation'' are used especially in technical or scientific contexts. In everyday English, words such as ''roughly'' or ''around'' are used with a similar meaning. It is often found abbreviated as ''approx.'' The term can be applied to various properties (e.g., value, quantity, image, description) that are nearly, but not exactly correct; similar, but not exactly the same (e.g., the approximate time was 10 o'clock). Although approximation is most often applied to numbers, it is also frequently applied to such things as Function (mathematics), mathematical functio ...

Linden-Limmer
Linden-Limmer ( ) is the tenth borough (''Stadtbezirk'') of Hanover, the state capital of Lower Saxony. It became part of the city in 1920.Klaus Mlynek et al., eds. (2009), ''Stadtlexikon Hannover'' Linden-Limmer is where Hannah Arendt was born. It has 44,941 inhabitants (2020) and consists of the quarters (''Stadtteile'') of Linden-Mitte (12,192 residents), Linden-Nord (16,433 residents), Linden-Süd (10,068 inhabitants) and Limmer (6,248 inhabitants). Linden The village of Linden was built around a count's court around the year 1100 on the northern slope of the Lindener Berg and developed into an industrial city during the 19th century before being incorporated into Hanover in 1920. Linden today consists of the quarters of Linden-Mitte, Linden-Nord and Linden-Süd. It is characterized by a diverse gastronomy scene and a high proportion of students and residents with a migrant background.

Vacuum Brake
The vacuum brake is a braking system employed on trains and introduced in the mid-1860s. A variant, the automatic vacuum brake system, became almost universal in British train equipment and in countries influenced by British practice. Vacuum brakes also enjoyed a brief period of adoption in the United States, primarily on narrow-gauge railroads. Their limitations caused them to be progressively superseded by compressed air systems starting in the United Kingdom from the 1970s onward. The vacuum brake system is now obsolete; it is not in large-scale usage anywhere in the world, other than in South Africa, largely supplanted by air brakes. Introduction In the earliest days of railways, trains were slowed or stopped by the application of manually applied brakes on the locomotive and in brake vehicles through the train, and later by steam power brakes on locomotives. This was clearly unsatisfactory, given the slow and unreliable response times (each brake being separately applied by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petrol Engine
A petrol engine (gasoline engine in American English) is an internal combustion engine designed to run on petrol (gasoline). Petrol engines can often be adapted to also run on fuels such as liquefied petroleum gas and ethanol blends (such as ''E10'' and ''E85''). Most petrol engines use spark ignition, unlike diesel engines which typically use compression ignition. Another key difference to diesel engines is that petrol engines typically have a lower compression ratio. Design Thermodynamic cycle Most petrol engines use either the four-stroke Otto cycle or the two-stroke cycle. Petrol engines have also been produced using the Miller cycle and Atkinson cycle. Layout Most petrol-powered piston engines are straight engines or V engines. However, flat engines, W engines and other layouts are sometimes used. Wankel engines are classified by the number of rotors used. Compression ratio Cooling Petrol engines are either air-cooled or water-cooled. Ignition Petrol e ...

Manchester
Manchester () is a city in Greater Manchester, England. It had a population of 552,000 in 2021. It is bordered by the Cheshire Plain to the south, the Pennines to the north and east, and the neighbouring city of Salford to the west. The two cities and the surrounding towns form one of the United Kingdom's most populous conurbations, the Greater Manchester Built-up Area, which has a population of 2.87 million. The history of Manchester began with the civilian settlement associated with the Roman fort ('' castra'') of ''Mamucium'' or ''Mancunium'', established in about AD 79 on a sandstone bluff near the confluence of the rivers Medlock and Irwell. Historically part of Lancashire, areas of Cheshire south of the River Mersey were incorporated into Manchester in the 20th century, including Wythenshawe in 1931. Throughout the Middle Ages Manchester remained a manorial township, but began to expand "at an astonishing rate" around the turn of the 19th century. Manchest ...
