Van Vlissingen En Dudok Van Heel
Van Vlissingen en Dudok van Heel was a famous nineteenth-century Dutch machine factory. It built steam engines and machinery for the sugar industry and for maritime purposes, as well ships, rolling stock and large metal structures like the Moerdijk bridge and a floating dock. In 1871 it was reorganized to become the public company Koninklijke Fabriek van Stoom- en andere Werktuigen. In a second reorganization in 1890, parts of it were saved and continued under the name Koninklijke Nederlandsche Fabriek van Werktuigen en Spoorwegmaterieel, renamed to Werkspoor in 1927. Van Vlissingen en Dudok van Heel Early years The company was founded as the 'Van Vlissingen' company in 1826. The founder was Paul van Vlissingen (1797–1876), who was also one of the founders of the Amsterdamsche Stoomboot Maatschappij (ASM). In 1828 Abraham Dudok van Heel (1802–1873), Abraham Dudok van Heel (1802–1873) became a partner, and the name was changed to Fabriek van Stoom- en Andere Werktuigen, ...

Casting (metalworking)
In metalworking and jewelry making, casting is a process in which a liquid metal is delivered into a mold (usually by a crucible) that contains a negative impression (i.e., a three-dimensional negative image) of the intended shape. The metal is poured into the mold through a hollow channel called a sprue. The metal and mold are then cooled, and the metal part (the ''casting'') is extracted. Casting is most often used for making complex shapes that would be difficult or uneconomical to make by other methods. Casting processes have been known for thousands of years, and have been widely used for sculpture (especially in bronze), jewelry in precious metals, and weapons and tools. Highly engineered castings are found in 90 percent of durable goods, including cars, trucks, aerospace, trains, mining and construction equipment, oil wells, appliances, pipes, hydrants, wind turbines, nuclear plants, medical devices, defense products, toys, and more. Traditional techniques include lost ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quintal
The quintal or centner is a historical unit of mass in many countries which is usually defined as 100 base units, such as pounds or kilograms. It is a traditional unit of weight in France, Portugal, and Spain and their former colonies. It is commonly used for grain prices in wholesale markets in Ethiopia and India, where 1 quintal = 100 kg. In British English, it referred to the hundredweight; in American English, it formerly referred to an uncommon measure of 100 kilograms. Languages drawing its cognate name for the weight from Romance languages include French, Portuguese, Romanian and Spanish , Italian , Esperanto , Polish . Languages taking their cognates from Germanicized ''centner'' include the German , Lithuanian , Swedish , Polish , Russian and Ukrainian (), Estonian and Spanish . Many European languages have come to translate both the imperial and American hundredweight as their cognate form of ''quintal'' or ''centner''. Name The concept has resulted in two ...

Lighter (barge)
A lighter is a type of flat-bottomed barge used to transfer goods and passengers to and from moored ships. Lighters were traditionally unpowered and were moved and steered using long oars called "sweeps" and the motive power of water currents. They were operated by skilled workers called lightermen and were a characteristic sight in London's docks until about the 1960s, when technological changes made this form of lightering largely redundant. Unpowered lighters continue to be moved by powered tugs, however, and lighters may also now themselves be powered. The term is also used in the Lighter Aboard Ship (LASH) system. The name itself is of uncertain origin, but is believed to possibly derive from an old Dutch or German word, ''lichten'' (to lighten or unload). In Dutch, the word ''lichter'' is still used for smaller ships that take over goods from larger ships. Lighters, albeit powered ones, were proposed to be used in 2007 at Port Lincoln and Whyalla in South Australia to load ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

's-Hertogenbosch
s-Hertogenbosch (), colloquially known as Den Bosch (), is a city and municipality in the Netherlands with a population of 157,486. It is the capital of the province of North Brabant and its fourth largest by population. The city is south of the Maas river and near the Waal; it is to the north east of the city of Tilburg, north west of Eindhoven, south west of Nijmegen, and a longer distance south of Utrecht and south east of Dordrecht. History The city's official name is a contraction of the (archaic) Dutch ''des Hertogen bosch'' — "the forest of the duke". The duke in question was Henry I of Brabant, whose family had owned a large estate at nearby Orthen for at least four centuries. He founded a new town located on some forested dunes in the middle of a marsh. At age 26, he granted 's-Hertogenbosch city rights and the corresponding trade privileges in 1185. This is, however, the traditional date given by later chroniclers; the first mention in contemporaneous sou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watergeus-class Sloop
The ''Watergeus'' class was a class of screw sloop-of-war of the Royal Netherlands Navy. The class comprised the 'Watergeus' and the Marnix. A third ship that had been planned was cancelled. Dutch Naval Plans in the 1860s The Secretary for the navy inherits a construction plan The career officer Willem Huyssen van Kattendijke Willem Johan Cornelis, Ridder Huijssen van Kattendijke (22 January 1816 – 6 February 1866) was a career officer of the Royal Dutch Navy and a politician. As an officer, he reached the rank of Commander. He was Dutch Naval Minister from 186 ... became Secretary for the navy on 14 March 1861. He of course inherited the ship-building program of his predecessor Mr. J.S. Lotsy, secretary for the navy from 1 August 1856 till 14 March 1861. This severely limited the new secretary's options for the East Indies. He first had to finish all 6 of the Djambi's laid down by his predecessor, before he could start to execute his own plans.

Djambi-class Corvette
The ''Djambi'' class was a class of steam corvettes of the Royal Netherlands Navy. The class comprised ''Djambi'', ''Zoutman'', ''Willem'', ''Leeuwarden'', ''Metalen Kruis'' and ''Curaçao''. Later two ships of a supposedly 'slightly revised' type were built, the Zilveren Kruis-class corvettes. Dutch Naval Plans in the 1850s Plan 1855 The Dutch naval plan 1855 called for a screw corvette of 250 hp as standard fighting warship for the East Indies. The steam corvettes of the ''Groningen'' class were the first of this type. They were designated as 'Steamships second class'. The ''Djambis were meant to supplement the number of these 'Steamships second class'. Corvettes and armored ships Even before the first of the Djambi class was launched, the whole class became technically obsolete when the French ironclad Gloire entered service in August 1860. The ''Djambis could not damage armored ships, and were slower than most of them. For service in the colonies however, many nations ...

HNLMS Adolf Van Nassau (1861)
HNLMS ''Adolf van Nassau'' was a unique ship built for the Royal Netherlands Navy. Context The ''Adolf van Nassau'' was part of the 1855 program that aimed to provide the Netherlands with a balanced fleet of screw propelled warships. The 1855 program called for three types of ships: frigates with auxiliary power of 400 hp; steam corvettes with 250 hp and steam sloops with 100 hp. The reason to create the program were the worries in the house of representatives about the state of the navy. There was a feeling that the navy was creating an enormous variety of ships, that would turn out to be inefficient and ineffective. The first frigate with auxiliary power was the ''Wassenaar'', a sail frigate converted during construction. The ships of the ''Evertsen'' class were laid down in 1854 and 1856 and were designed for auxiliary steam power. Meanwhile, the years between 1845 (acceptance of screw propulsion) and 1862 (Battle of Hampton Roads) were the most revolutionary ye ...

Rotational Speed
Rotational frequency (also known as rotational speed or rate of rotation) of an object Rotation around a fixed axis, rotating around an axis is the frequency of rotation of the object. Its unit is revolution per minute (rpm), cycle per second (cps), etc. The symbol for rotational frequency is \nu (the Greek alphabet, Greek lowercase letter Nu (letter), nu). Speed#Tangential speed, Tangential speed ''v'', rotational frequency \nu, and radial distance ''r'', are related by the following equation: :v = 2\pi r\nu :v = r\omega An algebraic rearrangement of this equation allows us to solve for rotational frequency: :\nu = v/2\pi r :\omega = v/r Thus, the tangential speed will be directly proportional to ''r'' when all parts of a system simultaneously have the same ''ω'', as for a wheel, disk, or rigid wand. The direct proportionality of ''v'' to ''r'' is not valid for the planets, because the planets have different rotational frequencies. Rotational frequency can measure, for e ...

Fan (machine)
A fan is a powered machine used to create a flow of air. A fan consists of a rotating arrangement of vanes or blades, generally made of wood, plastic, or metal, which act on the air. The rotating assembly of blades and hub is known as an ''impeller'', ''rotor'', or ''runner''. Usually, it is contained within some form of housing, or case. This may direct the airflow, or increase safety by preventing objects from contacting the fan blades. Most fans are powered by electric motors, but other sources of power may be used, including hydraulic motors, handcranks, and internal combustion engines. Mechanically, a fan can be any revolving wikt:vane#English, vane, or vanes used for producing air current, currents of air. Fans produce air flows with high volume and low pressure (although higher than ambient pressure), as opposed to gas compressor, compressors which produce high pressures at a comparatively low volume. A fan blade will often rotate when exposed to an air-fluid stream, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
