Motala Verkstad
AB Motala Verkstad is one of the oldest engineering companies in Sweden. The company was founded in 1822 during the construction of Göta Canal. Motala Verkstad has also built about 400 ships, 800 bridges (e.g. Västerbron, Skeppsholmsbron, Bergsnäsbron and the Ahvaz Bridge in Iran), railway equipment, 1300 locomotives. The 118-meter-tall towers of Uppsala Cathedral were also built by Motala Verkstad. During the 1970s the company was the world's largest exporter of kitchen sinks and during the 1980s they built landing gear for Swedish-built aircraft. Today the company employs about 180 people. History Motala Verkstad was started in 1822 on Baltzar von Platen's initiative. Von Platen realized the importance of having local technical knowledge during the construction of the channel.

Public Company
A public company is a company whose ownership is organized via shares of stock which are intended to be freely traded on a stock exchange or in over-the-counter markets. A public (publicly traded) company can be listed on a stock exchange (listed company), which facilitates the trade of shares, or not (unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are ''private'' enterprises in the ''private'' sector, and "public" emphasizes their reporting and trading on the public markets. Public companies are formed within the legal systems of particular states, and therefore have associations and formal designations which are distinct and separate in the polity in which they reside. In the United States, for example, a public company is usually a type of corporation (though a corporation need not be a public company), in the United Kingdom it is usually a public limited company (plc), i ...

Hildur-class Monitor
The ''Hildur-class'' monitors consisted of seven monitors built for the Swedish Navy in the 1870s. They were sold in 1919 and most were converted into fuel oil barges. One such ship, , has been converted into a museum ship. Design and description The ''Hildur''-class monitors were designed by Lieutenant John Christian d'Ailly, from a proposal by John Ericsson, for the defense of Lake Mälaren and the Stockholm archipelago. The ships were long overall and had a beam of . They had a draft of and displaced . The crew of the first two monitors, ''Hildur'' and ''Gerda'', numbered 42 officers and men, the others had 48-man crews. ''Hildur'' and ''Gerda'' only had a stern rudder, the other had rudders at bow and stern. Bow rudders were fitted to the older ships when they were reconstructed.Harris, pp. 30–32 The ''Hildur''s had a pair of two-cylinder horizontal-return connecting-rod steam engines, each driving a single propeller using steam from two cylindrical boilers.

Engineering Companies Of Sweden
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 ...

Nationalencyklopedin
''Nationalencyklopedin'' (; "The National Encyclopedia" in English), abbreviated NE, is a comprehensive contemporary Swedish-language encyclopedia, initiated by a favourable loan from the Government of Sweden of 17 million Swedish kronor in 1980, which was repaid by December 1990. The printed version consists of 20 volumes with 172,000 articles; the Internet version comprises 260,000 articles (as of June 2005). History The project was born in 1980, when a government committee suggested that negotiations be initiated with various publishers. This stage was finished in August 1985, when in Höganäs became the publisher responsible for the project. The project specifications were for a modern reference work based on a scientific paradigm incorporating gender and environmental issues. Pre-orders for the work were unprecedented; before the first volume was published in December 1989, 54,000 customers had ordered the encyclopedia. The last volume came out in 1996, with three suppl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nautilus (Verne)
''Nautilus'' is the fictional submarine belonging to Captain Nemo featured in Jules Verne's novels ''Twenty Thousand Leagues Under the Sea'' (1870) and ''The Mysterious Island'' (1874). Verne named the ''Nautilus'' after Robert Fulton's real-life submarine ''Nautilus'' (1800). For the design of the ''Nautilus'' Verne was inspired by the French Navy submarine ''Plongeur'', a model of which he had seen at the 1867 Exposition Universelle, three years before writing his novel. Description ''Nautilus'' is described by Verne as "a masterpiece containing masterpieces". It is designed and commanded by Captain Nemo. Electricity provided by sodium/mercury batteries (with the sodium provided by extraction from seawater) is the craft's primary power source for propulsion and other services. The energy needed to extract the sodium is provided by coal mined from the sea floor. ''Nautilus'' is double-hulled, and is further separated into water-tight compartments. Its top speed is . I ...

Submarine
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and Autonomous underwater vehicle, robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navy, navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, Blockade runner, blockade running, Ballistic missile submarine, nuclear deterrence, reconnaissance, conventio ...

Gear
A gear is a rotating circular machine part having cut teeth or, in the case of a cogwheel or gearwheel, inserted teeth (called ''cogs''), which mesh with another (compatible) toothed part to transmit (convert) torque and speed. The basic principle behind the operation of gears is analogous to the basic principle of levers. A gear may also be known informally as a cog. Geared devices can change the speed, torque, and direction of a power source. Gears of different sizes produce a change in torque, creating a mechanical advantage, through their ''gear ratio'', and thus may be considered a simple machine. The rotational speeds, and the torques, of two meshing gears differ in proportion to their diameters. The teeth on the two meshing gears all have the same shape. Two or more meshing gears, working in a sequence, are called a gear train or a '' transmission''. The gears in a transmission are analogous to the wheels in a crossed, belt pulley system. An advantage of gears is tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jules Verne
Jules Gabriel Verne (;''Longman Pronunciation Dictionary''. ; 8 February 1828 – 24 March 1905) was a French novelist, poet, and playwright. His collaboration with the publisher Pierre-Jules Hetzel led to the creation of the ''Voyages extraordinaires'', a series of bestselling adventure novels including ''Journey to the Center of the Earth'' (1864), ''Twenty Thousand Leagues Under the Seas'' (1870), and '' Around the World in Eighty Days'' (1872). His novels, always well documented, are generally set in the second half of the 19th century, taking into account the technological advances of the time. In addition to his novels, he wrote numerous plays, short stories, autobiographical accounts, poetry, songs and scientific, artistic and literary studies. His work has been adapted for film and television since the beginning of cinema, as well as for comic books, theater, opera, music and video games. Verne is considered to be an important author in France and most of Europe, where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Twenty Thousand Leagues Under The Sea
''Twenty Thousand Leagues Under the Seas'' (french: Vingt mille lieues sous les mers) is a classic science fiction adventure novel by French writer Jules Verne. The novel was originally serialized from March 1869 through June 1870 in Pierre-Jules Hetzel's fortnightly periodical, the . A deluxe octavo edition, published by Hetzel in November 1871, included 111 illustrations by Alphonse de Neuville and Édouard Riou. The book was widely acclaimed on its release and remains so; it is regarded as one of the premier adventure novels and one of Verne's greatest works, along with '' Around the World in Eighty Days'' and ''Journey to the Center of the Earth''. Its depiction of Captain Nemo's underwater ship, the ''Nautilus'', is regarded as ahead of its time, since it accurately describes many features of today's submarines, which in the 1860s were comparatively primitive vessels. A model of the French submarine ''Plongeur'' (launched in 1863) figured at the 1867 Exposition Universe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Science Fiction
Science fiction (sometimes shortened to Sci-Fi or SF) is a genre of speculative fiction which typically deals with imaginative and futuristic concepts such as advanced science and technology, space exploration, time travel, parallel universes, extraterrestrial life, sentient artificial intelligence, cybernetics, certain forms of immortality (like mind uploading), and the singularity. Science fiction predicted several existing inventions, such as the atomic bomb, robots, and borazon, whose names entirely match their fictional predecessors. In addition, science fiction might serve as an outlet to facilitate future scientific and technological innovations. Science fiction can trace its roots to ancient mythology. It is also related to fantasy, horror, and superhero fiction and contains many subgenres. Its exact definition has long been disputed among authors, critics, scholars, and readers. Science fiction, in literature, film, television, and other media, has beco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SS Valkyrian
The ''Drottningholm'' is a Swedish steam ship that was built in 1909 at Motala Verkstads Nya AB as the ''Valkyrian'', and was also briefly known as the ''Nya Strömma Kanal''. Given her current name in 1969, she now operates cruises and charters for the Strömma Kanalbolaget and is a listed historic ship of Sweden. History ''Valkyrian'' was built by the Motala Verkstads Nya AB in Motala and delivered in May 1909 to the ''Stockholms Ångslups AB'' (Stockholm Steam Launch AB) of Stockholm for use on a service between Stockholm and Lidingö. She was a sister ship to ''Angantyr'', built the same year. She was rebuilt in 1914 with an upper deck superstructure. In 1918, ''Valkyrian'' was sold to Waxholms Nya Ångfartygs AB, better known as Waxholmsbolaget. In the 1940s a new boiler was fitted, and the upper deck was remodelled with a large seating area in 1949. In 1964, she was sold back to Stockholms Ångslups AB, who sold her to Järnvägs AB Stockholm - Saltsjön the following ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
