Amsterdamsche Droogdok Maatschappij
Amsterdamsche Droogdok Maatschappij (ADM) was a Dutch company that repaired ships using dry docks in Amsterdam, Netherlands. After World War II it also built some ships. Context Port of Amsterdam By the early 19th century the once famous commercial center Amsterdam had a very poor connection to the sea. The situation improved by the construction of the Noordhollandsch Kanaal, completed in 1824. It soon turned out that by itself, the canal did not create a suitable port for Amsterdam. This was done by creating the wet docks Oosterdok and Westerdok. Outside of these docks, docking was hindered by tides and other inconveniences. Inside these docks, the 'Rederij der Drijvende Droogdokken' (floating dry docks shipping line) built three wooden floating dry docks in the 1840s. The first of these, Amsterdam Wooden Drydock I can be considered to have been the first modern floating dry dock in Europe. The North Sea Canal By the 1850s it was clear that Amsterdam needed a more dir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nederlandsche Dok En Scheepsbouw Maatschappij
The Nederlandsche Dok en Scheepsbouw Maatschappij (NDSM) (Dutch: ''Netherlands dock and shipbuilding company''), was a shipbuilding and repair company based in Amsterdam in the Netherlands, existing from 1946 to 1979. The area of about 80 hectares has since 2013 been transformed into a modern city district as a distinct part of Amsterdam-Noord and is still under development. The industrial wharfs and structures have been replaced by apartment buildings and hospitality industry, still called NDSM. Foundation Partnership turned into Public Company The company came into existence as a general partnership named Nederlandsche Dok en Scheepsbouw Maatschappij (NDSM), founded by Nederlandsche Scheepsbouw Maatschappij (NSM) and Nederlandsche Dok Maatschappij (NDM) both from Amsterdam. On 27 February 1946 this partnership was confirmed by the shareholders of both companies. The partnership would soon be turned into the public company NDSM NV. All assets would be handed to NDSM, and sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Koninklijke Nederlandse Stoomboot-Maatschappij
The Koninklijke Nederlandse Stoomboot-Maatschappij (KNSM) (Royal Netherlands Steamship Company) was an Amsterdam-based shipping company that existed from 1856 to 1981. It was once the largest company in Amsterdam and one of the top five shipping lines in the Netherlands. The company operated mid-sized freighters that had limited passenger accommodations. At its peak in 1939, the company had 79 vessels. Of these, 48 were lost during World War II. Context (1827-1856) Economical and technical developments In 1827 the Amsterdamsche Stoomboot Maatschappij (ASM) had tried to establish a steamship line from Amsterdam to London, but the line proved economically unviable. A few decades later, the general economic circumstances had changed: In 1846, the Corn Laws had been cancelled. It was also known that the Navigation Acts would be cancelled in 1849. Furthermore, the railroad from Amsterdam had finally reached the Rhine. Also in the 1840s, some technological innovations changed th ...

Amsterdam Wooden Drydock II
Amsterdam Wooden Drydock II was the second floating dry dock of Amsterdam, and was moored in the Westerdok. Context A floating Dry dock in the Amsterdam Wet Docks In November 1842 Amsterdam Wooden Drydock I, the first dry dock of Amsterdam had opened. It was a wooden floating dry dock, and was an immediate success, servicing 64 ships in just under a year. At the time Amsterdam had two large wet docks: Westerdok and Oosterdok. Drydock I was situated in the more important Oosterdok. Rederij der Drijvende Droogdokken The Rederij der Drijvende Droogdokken held a license to the patent to operate dry docks in Amsterdam for 5 years, i.e. till December 1846. In order to protect its investments, it would be logical to want to try to prolong this right, and to keep out the competition. Both required the Rederij der Drijvende Droogdokken to realize a second dry dock before the extinction of the patent. Primarily because an attempt to prolong the patent was not likely to be succes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amsterdam Kaart Meyers Großes Konversations-Lexikon 1905
Amsterdam ( , , , lit. ''The Dam on the River Amstel'') is the capital and most populous city of the Netherlands, with The Hague being the seat of government. It has a population of 907,976 within the city proper, 1,558,755 in the urban area and 2,480,394 in the metropolitan area. Located in the Dutch province of North Holland, Amsterdam is colloquially referred to as the " Venice of the North", for its large number of canals, now designated a UNESCO World Heritage Site. Amsterdam was founded at the mouth of the Amstel River that was dammed to control flooding; the city's name derives from the Amstel dam. Originally a small fishing village in the late 12th century, Amsterdam became a major world port during the Dutch Golden Age of the 17th century, when the Netherlands was an economic powerhouse. Amsterdam is the leading center for finance and trade, as well as a hub of production of secular art. In the 19th and 20th centuries, the city expanded and many new neighborhoods ...

Belt (mechanical)
A belt is a loop of flexible material used to link two or more rotating shafts mechanically, most often parallel. Belts may be used as a source of motion, to transmit power efficiently or to track relative movement. Belts are looped over pulleys and may have a twist between the pulleys, and the shafts need not be parallel. In a two pulley system, the belt can either drive the pulleys normally in one direction (the same if on parallel shafts), or the belt may be crossed, so that the direction of the driven shaft is reversed (the opposite direction to the driver if on parallel shafts). The belt drive can also be used to change the speed of rotation, either up or down, by using different sized pulleys. As a source of motion, a conveyor belt is one application where the belt is adapted to carry a load continuously between two points. History The mechanical belt drive, using a pulley machine, was first mentioned in the text the ''Dictionary of Local Expressions'' by the Han Dynas ...

Line Shaft
A line shaft is a power-driven rotating shaft for power transmission that was used extensively from the Industrial Revolution until the early 20th century. Prior to the widespread use of electric motors small enough to be connected directly to each piece of machinery, line shafting was used to distribute power from a large central power source to machinery throughout a workshop or an industrial complex. The central power source could be a water wheel, turbine, windmill, animal power or a steam engine. Power was distributed from the shaft to the machinery by a system of belts, pulleys and gears known as ''millwork''. Operation A typical line shaft would be suspended from the ceiling of one area and would run the length of that area. One pulley on the shaft would receive the power from a parent line shaft elsewhere in the building. The other pulleys would supply power to pulleys on each individual machine or to subsequent line shafts. In manufacturing where there were ...

Planer (metalworking)
A planer is a type of metalworking machine tool that uses linear relative motion between the workpiece and a single-point cutting tool to cut the work piece.Parker, Dana T. ''Building Victory: Aircraft Manufacturing in the Los Angeles Area in World War II,'' p. 73, Cypress, CA, 2013. . A planer is similar to a shaper, but larger, and with workpiece moving, whereas in a shaper the cutting tool moves. Applications Linear planing The most common applications of planers and shapers are linear-toolpath ones, such as: * Generating accurate flat surfaces. (While not as precise as grinding, a planer can remove a tremendous amount of material in one pass with high accuracy.) * Cutting slots (such as keyways). * It is even possible to do work that might now be done by wire EDM in some cases. Starting from a drilled or cored hole, a planer with a boring-bar type tool can cut internal features that don't lend themselves to milling or boring (such as irregularly shaped holes with tight c ...

Steam Hammer
A steam hammer, also called a drop hammer, is an industrial power hammer driven by steam that is used for tasks such as shaping forgings and driving piles. Typically the hammer is attached to a piston that slides within a fixed cylinder, but in some designs the hammer is attached to a cylinder that slides along a fixed piston. The concept of the steam hammer was described by James Watt in 1784, but it was not until 1840 that the first working steam hammer was built to meet the needs of forging increasingly large iron or steel components. In 1843 there was an acrimonious dispute between François Bourdon of France and James Nasmyth of Britain over who had invented the machine. Bourdon had built the first working machine, but Nasmyth claimed it was built from a copy of his design. Steam hammers proved to be invaluable in many industrial processes. Technical improvements gave greater control over the force delivered, greater longevity, greater efficiency and greater power. A ...
