Gustav Adolph Hagemann
Gustav Adolph Hagemann (16 May 1842 – 26 April 1916) was a Danish engineer and businessman. He was chief technical officer of the Danish Sugar Factories from 1872 to 1897 and then served as chairman of the board until 1916. He owned several sugar plantations on Saint Croix in the Danish West Indies. Early life and education Hagemann was born on the Rodsteenseje estate at Odder in 1842, the son of Otto Waldemar Hagemann (1809–1890) and Sophie Marie Poulsen (1815–1901). His father owned the estate until 1857 when he returned to Holstein. Hagemann went to school in Aarhus before studying Applied Sciences at the College of Advanced Technology in Copenhagen from 1860 to 1865. Career Hagemann was employed by the Øresund cryolite factory () in 1864. In 1865, when he had completed his exams, sent him to the US to oversee the deliveries of cryolite to the Pennsylvania Salt Manufacturing Company. In early 1856, he travelled to the US to provide technical support in connection ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Technical University Of Denmark
The Technical University of Denmark ( da, Danmarks Tekniske Universitet), often simply referred to as DTU, is a polytechnic university and school of engineering. It was founded in 1829 at the initiative of Hans Christian Ørsted as Denmark's first polytechnic, and it is today ranked among Europe's leading engineering institutions. It is located in the town Kongens Lyngby, north of central Copenhagen, Denmark. Along with École Polytechnique in Paris, École Polytechnique Fédérale de Lausanne, Eindhoven University of Technology, Technical University of Munich and Technion – Israel Institute of Technology, DTU is a member of EuroTech Universities Alliance. History DTU was founded in 1829 as the "College of Advanced Technology" (Danish: Den Polytekniske Læreanstalt). The Physicist Hans Christian Ørsted, at that time a professor at the University of Copenhagen, was one of the driving forces behind this initiative. He was inspired by the École Polytechnique in Paris, Fran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salt Well
A salt well (or brine well) is used to mine salt from caverns or deposits. Water is used as a solution to dissolve the salt or halite deposits so that they can be extracted by pipe to an evaporation process, which results in a brine or dry product for sale or use. In the United States during the 19th century, salt wells were a significant source of income for operators and the government. Locating underground salt deposits was usually based on locations of existing salt springs. In mountainous areas, a similar technique called sink works (from German ''sinkwerk'') is used. History The Chinese have been using brine wells and a form of salt solution mining as part of their civilization for more than 2000 years. The first recorded salt well in China was dug in the Sichuan province around 2,250 years ago. This was the first time that ancient water well technology was applied successfully for the exploitation of salt, and marked the beginning of Sichuan’s salt drilling industry. S ...

Wheel Of Fortune, U
A wheel is a circular component that is intended to rotate on an axle bearing. The wheel is one of the key components of the wheel and axle which is one of the six simple machines. Wheels, in conjunction with axles, allow heavy objects to be moved easily facilitating movement or transportation while supporting a load, or performing labor in machines. Wheels are also used for other purposes, such as a ship's wheel, steering wheel, potter's wheel, and flywheel. Common examples are found in transport applications. A wheel reduces friction by facilitating motion by rolling together with the use of axles. In order for wheels to rotate, a moment needs to be applied to the wheel about its axis, either by way of gravity or by the application of another external force or torque. Using the wheel, Sumerians invented a device that spins clay as a potter shapes it into the desired object. Terminology The English word ''wheel'' comes from the Old English word , from Proto-German ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
