Heinrich Koppers
Heinrich Koppers (November 23, 1872 – September 5, 1941) was a German engineer. Koppers developed a new type of coke oven that economically recovered the byproduct chemicals of the coking process. The design of these ovens was superior to other ovens. Having previously worked at other German companies, he founded his own company ''Heinrich Koppers AG'' in 1901 to successfully exploit the patents he had been granted in the area of coke oven design. The headquarters of ''Heinrich Koppers AG'' were in Essen - Moltkeviertel, adjacent to the mansion of the ''Koppers'' family (both buildings built in 1911). After meeting with US Steel in 1907, Koppers agreed to build a coke plant in the United States and formed the H. Koppers Company. In 1912, the H. Koppers Company was incorporated to be Koppers Inc. in Chicago, Illinois, an industrial organization which moved to Pittsburgh, Pennsylvania, United States in 1914. In 1914, Koppers sold his controlling stake in Koppers Inc. to in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kobuta, Pennsylvania
Kobuta is an unincorporated community in Potter Township, Beaver County, Pennsylvania, United States. It is located along the Ohio River, due west of Monaca, southwest of Industry, and southwest of Beaver. The area was the site of a butadiene, and later a foamed polystyrene, chemical plant during World War II and in the 1950s, owned by the Koppers United Company, predecessor to Koppers Company, Inc.

Wood Preservation
Wood easily degrades without sufficient preservation. Apart from structural wood preservation measures, there are a number of different chemical preservatives and processes (also known as "timber treatment", "lumber treatment" or "pressure treatment") that can extend the life of wood, timber, and their associated products, including engineered wood. These generally increase the durability and resistance from being destroyed by insects or fungi. History As proposed by Richardson, treatment of wood has been practiced for almost as long as the use of wood itself. There are records of wood preservation reaching back to ancient Greece during Alexander the Great's rule, where bridge wood was soaked in olive oil. The Romans protected their ship hulls by brushing the wood with tar. During the Industrial Revolution, wood preservation became a cornerstone of the wood processing industry. Inventors and scientists such as Bethell, Boucherie, Burnett and Kyan made historic developments in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andrew Mellon
Andrew William Mellon (; March 24, 1855 – August 26, 1937), sometimes A. W. Mellon, was an American banker, businessman, industrialist, philanthropist, art collector, and politician. From the wealthy Mellon family of Pittsburgh, Pennsylvania, he established a vast business empire before moving into politics. He served as United States Secretary of the Treasury from March 9, 1921 to February 12, 1932, presiding over the boom years of the 1920s and the Wall Street crash of 1929. A conservative Republican, Mellon favored policies that reduced taxation and the national debt in the aftermath of World War I. Mellon's father, Thomas Mellon, rose to prominence in Pittsburgh as a banker and attorney. Andrew began working at his father's bank, T. Mellon & Sons, in the early 1870s, eventually becoming the leading figure in the institution. He later renamed T.

Sound Trap
A sound attenuator, or duct silencer, sound trap, or muffler, is a noise control acoustical treatment of Heating Ventilating and Air-Conditioning (HVAC) ductwork designed to reduce transmission of noise through the ductwork, either from equipment into occupied spaces in a building, or between occupied spaces. In its simplest form, a sound attenuator consists of a baffle within the ductwork. These baffles often contain sound-absorbing materials. The physical dimensions and baffle configuration of sound attenuators are selected to attenuate a specific range of frequencies. Unlike conventional internally-lined ductwork, which is only effective at attenuating mid- and high-frequency noise, sound attenuators can achieve broader band attenuation in relatively short lengths. Certain types of sound attenuators are essentially a Helmholtz resonator used as a passive noise-control device. Configuration Generally, sound attenuators consist of the following elements: * An inner perfora ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethylene
Ethylene (IUPAC name: ethene) is a hydrocarbon which has the formula or . It is a colourless, flammable gas with a faint "sweet and musky" odour when pure. It is the simplest alkene (a hydrocarbon with carbon-carbon double bonds). Ethylene is widely used in the chemical industry, and its worldwide production (over 150 million tonnes in 2016) exceeds that of any other organic compound. Much of this production goes toward polyethylene, a widely used plastic containing polymer chains of ethylene units in various chain lengths. Ethylene is also an important natural plant hormone and is used in agriculture to force the ripening of fruits. The hydrate of ethylene is ethanol. Structure and properties This hydrocarbon has four hydrogen atoms bound to a pair of carbon atoms that are connected by a double bond. All six atoms that comprise ethylene are coplanar. The H-C-H angle is 117.4°, close to the 120° for ideal sp² hybridized carbon. The molecule is also relatively weak: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
