Emmen, Netherlands
Emmen () is a municipality and town of the province of Drenthe in the northeastern Netherlands. History A planned city, Emmen arose from several small farming and peat-harvesting communities which have dotted the province of Drenthe since the Middle Ages. Traces of these communities can still be seen in the form of the villages of Westenesch, Noordbarge and Zuidbarge: they have a separate history and layout but are surrounded by the suburbs and the center of Emmen. The expansion of the town did not happen until after the Second World War. Suburbs were built around the old center of Emmen, starting with Emmermeer directly to the north, and followed to the south-east by Angelslo (for which an old village of the same name was demolished), Emmerhout (famed at the time for being separated from the town by an existing forest) to the east, Bargeres, the Rietlanden and Parc Sandur to the south and south-west. Construction of the last suburb, called Delftlanden, is well underw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centrifugal Switch
A centrifugal switch is an electric switch that operates using the centrifugal force created from a rotating shaft, most commonly that of an electric motor or gasoline engine. The switch is designed to activate or de-activate as a function of the rotational speed of the shaft. History A 1927 patent for a centrifugal switch (US Patent #1,630,394) was granted to Royal Lee on May 31, 1927. It was the basis for the formation of the Lee Engineering Company. Applications Electric motors Perhaps the most common use of centrifugal switches is within single-phase, split-phase induction motors. Here, the switch is used to disconnect the starting winding of the motor once the motor approaches its normal operating speed. In this case, the centrifugal switch consists of weights mounted to the shaft of the motor and held near the shaft by spring force. At rest, levers attached to the weights press a low-friction, non-conductive plate against a set of electrical contacts mounted to the ...

Roundup (history)
A roundup is a police operation of interpellation and arrest of people taken at random from a public place, or targeting a particular population by ethnicity, appearance, or other perceived membership in a targeted group. To ensure operational success, organizers rely on the element of surprise in order to reduce the risk of evasion as much as possible. When the operation involves large numbers of individuals not targeted for any perceived group membership, it may be called a mass arrest.

The "Alfred Teves Maschinen- und Armaturenfabrik" company became one of the largest suppliers of components and sub-assemblies to the German auto-industry. It was rebranded during the early 1920s, more succinctly, as "ATE". Life Provenance and early years Alfred Teves was born in Trittau, a small town in Schleswig-Holstein, located some 30 km (20 miles) east of Hamburg.

Rotterdam Blitz
Rotterdam was subjected to heavy aerial bombardment by the ''Luftwaffe'' during the German invasion of the Netherlands in World War II. The objective was to support the German troops fighting in the city, break Dutch resistance and force the Dutch army to surrender. Bombing began at the outset of hostilities on 10 May and culminated with the destruction of the entire historic city centre on 14 May, an event sometimes referred to as the Rotterdam Blitz. According to an official list published in 2022 at least 1,150 people were killed (with 711 deaths in the 14 May bombing alone) and 85,000 more were left homeless. The psychological and physical success of the raid, from the German perspective, led the ''Oberkommando der Luftwaffe'' (OKL) to threaten to destroy the city of Utrecht if the Dutch command did not surrender. The Dutch surrendered in the late afternoon of 14 May, signing the capitulation early the next morning. Prelude The strategic location of the Netherlands between ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overschie
Overschie is a neighborhood of Rotterdam, Netherlands, formerly a separate village with its own municipality. The village of Overschie was located on the intersection of four rivers called "Schie": the Delftsche Schie, Schiedamsche Schie, Delfshavensche Schie, and Rotterdamsche Schie. It was a separate municipality between 1817 and 1941, when it merged with Rotterdam. Immediately after the Second World War, the construction of a large suburb was begun southeast of the village.

Casting
Casting is a manufacturing process in which a liquid material is usually poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solidified part is also known as a ''casting'', which is ejected or broken out of the mold to complete the process. Casting materials are usually metals or various ''time setting'' materials that cure after mixing two or more components together; examples are epoxy, concrete, plaster and clay. Casting is most often used for making complex shapes that would be otherwise difficult or uneconomical to make by other methods. Heavy equipment like machine tool beds, ships' propellers, etc. can be cast easily in the required size, rather than fabricating by joining several small pieces. Casting is a 7,000-year-old process. The oldest surviving casting is a copper frog from 3200 BC. History Throughout history, metal casting has been used to make tools, weapons, and religious objects. Metal casting history and de ...

Musselkanaal
Musselkanaal (also: ''Stads-Musselkanaal''; Gronings: ''Muzzelknoal'') is a town in the Netherlands, Dutch province of Groningen (province), Groningen. It is located in the municipality of Stadskanaal. It was established by the Groningen, city of Groningen in the 1840s to exploit the peat. It used to be part of the municipality of Onstwedde, but was merged into Stadskanaal in 1968. History The Bourtange moor was located in the south-east of Groningen. It was a raised bog with few inhabitants. Around 1600, corporations started to exploit the peat. In 1635, the Groningen, city of Groningen took control, and established the , as a colony. The colony had advanced to Stadskanaal where it ended due to a border conflict with the province of Drenthe. In 1615, the border had been defined by the Semslinie, and the village and monastery of Ter Apel was assigned to Drenthe. In 1817, the line was modified with the so-called ''Koningsraai'' which assigned Ter Apel to Groningen. In 1819, Groning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blacksmith
A blacksmith is a metalsmith who creates objects primarily from wrought iron or steel, but sometimes from #Other metals, other metals, by forging the metal, using tools to hammer, bend, and cut (cf. tinsmith). Blacksmiths produce objects such as gates, grilles, railings, light fixtures, furniture, sculpture, tools, agricultural implements, decorative and religious items, cooking utensils, and weapons. There was an historical distinction between the heavy work of the blacksmith and the more delicate operation of a whitesmith, who usually worked in Goldsmith, gold, Silversmith, silver, pewter, or the finishing steps of fine steel. The place where a blacksmith works is called variously a smithy, a forge or a blacksmith's shop. While there are many people who work with metal such as farriers, wheelwrights, and Armourer, armorers, in former times the blacksmith had a general knowledge of how to make and repair many things, from the most complex of weapons and armor to simple things ...
