Herräng
Herräng () is the northernmost locality in Norrtälje Municipality, Stockholm County, Sweden, with 422 inhabitants in 2010. It is located 40 kilometres north of the municipal seat Norrtälje along the coast of Singöfjärden, a bay on Roslagen. The town has a history of industry and mining. Today it is known mainly for being the site of one of the largest lindy hop dance camps in the world, the Herräng Dance Camp. Industrial history Herräng and the area with ore findings that the town is situated close to, ''Herrängsfältet'' is the biggest mining area within Stockholm County. Iron ore has been mined in Herräng since the late 16th century. The place was then known as ''Kuggvass'', and one interpretation of the name is that cogs from the Hanseatic League used to land at the place. The mines were situated by the coast, without any source of water power to pump water from the mine, which kept the mining activities at a low level. In 1753, a stream further away south of the bay ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Norrtälje Municipality
Norrtälje Municipality (''Norrtälje kommun'') is a municipality in Stockholm County in east central Sweden. Its seat is located in the city of Norrtälje. It is the largest and northernmost municipality of Stockholm County and was created in 1971 through the amalgamation of several former municipalities. There are 25 original local government units (as of 1863) combined in the present municipality. Many of the houses in Norrtälje municipality are summer cottages, only inhabited during summertime. This is due to its geographical location by the Stockholm archipelago, which makes it popular among Stockholmers and tourists.

Stockholm County
Stockholm County ( sv, Stockholms län, link=no ) is a county or '' län'' (in Swedish) on the Baltic Sea coast of Sweden. It borders Uppsala County and Södermanland County. It also borders Mälaren and the Baltic Sea. The city of Stockholm is the capital of Sweden. Stockholm County is divided by the historic provinces of Uppland (Roslagen) and Södermanland (Södertörn). More than one fifth of the Swedish population lives in the county. Stockholm County is also one of the statistical '' riksområden'' (national areas) according to NUTS:SE, Nomenclature of Territorial Units for Statistics within the EU. With more than two million inhabitants, Stockholm is the most densely populated county of Sweden. History Stockholm County was established in 1714. The City of Stockholm then constituted its own administrative entity under the Governor of Stockholm and was not part of Stockholm County. Though outside Stockholm County, the City of Stockholm was its seat. On 1 January 196 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Country
A country is a distinct part of the world, such as a state, nation, or other political entity. It may be a sovereign state or make up one part of a larger state. For example, the country of Japan is an independent, sovereign state, while the country of Wales is a component of a multi-part sovereign state, the United Kingdom. A country may be a historically sovereign area (such as Korea), a currently sovereign territory with a unified government (such as Senegal), or a non-sovereign geographic region associated with certain distinct political, ethnic, or cultural characteristics (such as the Basque Country). The definition and usage of the word "country" is flexible and has changed over time. ''The Economist'' wrote in 2010 that "any attempt to find a clear definition of a country soon runs into a thicket of exceptions and anomalies." Most sovereign states, but not all countries, are members of the United Nations. The largest country by area is Russia, while the smallest is ...

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] |
Headframe
A headframe (also known as a gallows frame, winding tower, hoist frame,Ernst, Dr.-Ing. Richard (1989). ''Wörterbuch der Industriellen Technik'' (5th ed.). Wiesbaden: Oscar Brandstetter, 1989. pit frame, shafthead frame, headgear, headstock or poppethead) is the structural frame above an underground mine shaft so as to enable the hoisting of machinery, personnel, or materials. Design Modern headframes are built out of steel, concrete or a combination of both. Timber headframes are no longer used in industrialized countries, but are still used in developing nations. Conventionally steel headframes are used when a drum hoist is employed, and concrete headframes are built for friction hoists; however a steel headframe can be used with a friction hoist for shafts with a smaller capacity and depth. Steel headframes A steel headframe is less expensive than a concrete headframe; the tallest steel headframe measures 87 m. Steel headframes are more adaptable to modifications (mak ...

Foundry
A foundry is a factory that produces metal castings. Metals are cast into shapes by melting them into a liquid, pouring the metal into a mold, and removing the mold material after the metal has solidified as it cools. The most common metals processed are aluminum and cast iron. However, other metals, such as bronze, brass, steel, magnesium, and zinc, are also used to produce castings in foundries. In this process, parts of desired shapes and sizes can be formed. Foundries are one of the largest contributors to the manufacturing recycling movement, melting and recasting millions of tons of scrap metal every year to create new durable goods. Moreover, many foundries use sand in their molding process. These foundries often use, recondition, and reuse sand, which is another form of recycling. Process In metalworking, casting involves pouring liquid metal into a mold, which contains a hollow cavity of the desired shape, and then allowing it to cool and solidify. The solidified pa ...

Blast Furnace
A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. ''Blast'' refers to the combustion air being "forced" or supplied above atmospheric pressure. In a blast furnace, fuel ( coke), ores, and flux (limestone) are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with oxygen enrichment) is blown into the lower section of the furnace through a series of pipes called tuyeres, so that the chemical reactions take place throughout the furnace as the material falls downward. The end products are usually molten metal and slag phases tapped from the bottom, and waste gases (flue gas) exiting from the top of the furnace. The downward flow of the ore along with the flux in contact with an upflow of hot, carbon monoxide-rich combustion gases is a countercurrent exchange and chemical reaction process. In contrast, air furnaces (such as reverbera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ironworks
An ironworks or iron works is an industrial plant where iron is smelted and where heavy iron and steel products are made. The term is both singular and plural, i.e. the singular of ''ironworks'' is ''ironworks''. Ironworks succeeded bloomeries when blast furnaces replaced former methods. An integrated ironworks in the 19th century usually included one or more blast furnaces and a number of puddling furnaces or a foundry with or without other kinds of ironworks. After the invention of the Bessemer process, converters became widespread, and the appellation steelworks replaced ironworks. The processes carried at ironworks are usually described as ferrous metallurgy, but the term siderurgy is also occasionally used. This is derived from the Greek words ''sideros'' - iron and ''ergon'' or ''ergos'' - work. This is an unusual term in English, and it is best regarded as an anglicisation of a term used in French, Spanish, and other Romance languages. Historically, it is common ...

Dannemora, Sweden
Dannemora is an old mining town and a locality situated in Östhammar Municipality, Uppsala County, Sweden. It had 213 inhabitants in 2010. Dannemora mine Dannemora is the location of an important iron ore mine, the Dannemora mine, which formed the basis of the iron industry in Uppland. It provided the raw material for about 20 finery forges that produced bar iron for export. In the early mid-19th century, numerous workers from this town emigrated to the United States, with some settling in upstate New York at the site of other iron mines. They named the community Dannemora, after their former home. In England, iron produced from Dannemora ore was known as ''oregrounds iron'', after the port town of Öregrund, from which it was shipped. Bar iron from these forges was considered the best raw material for producing blister steel by the cementation process, owing mainly to the extremely low levels of sulphur and phosphorus in the ores, and their relatively high manganese content.

The Times
''The Times'' is a British daily national newspaper based in London. It began in 1785 under the title ''The Daily Universal Register'', adopting its current name on 1 January 1788. ''The Times'' and its sister paper ''The Sunday Times'' (founded in 1821) are published by Times Newspapers, since 1981 a subsidiary of News UK, in turn wholly owned by News Corp. ''The Times'' and ''The Sunday Times'', which do not share editorial staff, were founded independently and have only had common ownership since 1966. In general, the political position of ''The Times'' is considered to be centre-right. ''The Times'' is the first newspaper to have borne that name, lending it to numerous other papers around the world, such as ''The Times of India'', ''The New York Times'', and more recently, digital-first publications such as TheTimesBlog.com (Since 2017). In countries where these other titles are popular, the newspaper is often referred to as , or as , although the newspaper is of nationa ...

Steam Engine
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine. Steam engines are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including boilers etc.), such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, as in the beam engine and stationary steam engine. Although steam-driven devices were known as early as the aeolipile in the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
