Edward G. Acheson
Edward Goodrich Acheson (March 9, 1856 – July 6, 1931) was an American chemist. Born in Washington, Pennsylvania, he was the inventor of the Acheson process, which is still used to make Silicon carbide (carborundum) and later a manufacturer of carborundum and graphite. Biography Acheson (1856–1931) was raised in the coal fields of southwestern Pennsylvania. Acheson attended the Bellefonte Academy for three years, 1870–72; this being the totality of his formal education. He left school at the age of 16 to help support his family after his father died, and worked as a surveying assistant for the Pittsburgh Southern Railroad. He devoted his evenings to scientific pursuits—primarily electrical experiments. In 1880 he had the temerity to attempt to sell a battery of his own invention to Thomas Edison and wound up being hired. Edison put him to work on September 12, 1880 at his Menlo Park, New Jersey laboratory under John Kruesi. Acheson experimented on making a con ...

Menlo Park, New Jersey
Menlo Park is an unincorporated community located within Edison Township in Middlesex County, New Jersey, United States. In 1876, Thomas Edison set up his home and research laboratory in Menlo Park, which at the time was the site of an unsuccessful real estate development named after the town of Menlo Park, California. While there, he earned the nickname "the Wizard of Menlo Park".Walsh, Bryan"The Electrifying Edison" Web: ''Time'' 5 Jul 2010. The Menlo Park lab was significant in that it was one of the first laboratories to pursue practical, commercial applications of research. It was in his Menlo Park laboratory that Thomas Edison invented the phonograph and developed a commercially viable incandescent light bulb filament. Christie Street in Menlo Park was one of the first streets in the world to use electric lights for illumination. Edison left Menlo Park and moved his home and laboratory to West Orange, New Jersey in 1887. After his death, the Thomas Alva Edison Memorial To ...

Electric Smelting And Aluminum Company
The Electric Smelting and Aluminum Company, founded as Cowles Electric Smelting and Aluminum Company, and Cowles Syndicate Company, Limited, formed in the United States and England during the mid-1880s to extract and supply valuable metals. Founded by two brothers from Ohio, the Cowles companies are remembered for producing alloys in quantity sufficient for commerce. Their furnaces were electric arc smelters, one of the first viable methods for extracting metals. The businesses of the era dramatically increased the supply of aluminium, a plentiful resource not found in nature in pure form, and reduced its price. The Cowles process was the immediate predecessor to the Hall-Héroult process—today in nearly universal use more than a century after it was discovered by Charles Martin Hall and Paul Héroult and adapted by others including Carl Josef Bayer. Because of the patent landscape, the Cowles companies found themselves in court. Judges eventually acknowledged their innovations m ...

Synthetic Diamond
Lab-grown diamond (LGD; also called laboratory-grown, laboratory-created, man-made, artisan-created, artificial, synthetic, or cultured diamond) is diamond that is produced in a controlled technological process (in contrast to naturally formed diamond, which is created through geological processes and obtained by mining). Unlike diamond simulants (imitations of diamond made of superficially-similar non-diamond materials), synthetic diamonds are composed of the same material as naturally formed diamonds – pure carbon crystallized in an isotropic 3D form – and share identical chemical and physical properties. Numerous claims of diamond synthesis were reported between 1879 and 1928; most of these attempts were carefully analyzed but none was confirmed. In the 1940s, systematic research of diamond creation began in the United States, Sweden and the Soviet Union, which culminated in the first reproducible synthesis in 1953. Further research activity yielded the discoveries of HP ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Antwerp City Hall
The City Hall (Dutch: ) of Antwerp, Belgium, stands on the western side of Antwerp's Grote Markt ("Great Market Square"). Erected between 1561 and 1565 after designs made by Cornelis Floris de Vriendt and several other architects and artists, this Renaissance building incorporates both Flemish and Italian influences. The Stadhuis is listed as one of the Belfries of Belgium and France, a UNESCO World Heritage Site. History In the 16th century Antwerp became one of the busiest trading ports and most prosperous cities in Northern Europe. The municipal authorities wished to replace Antwerp's small medieval town hall with a more imposing structure befitting the prosperity of the great port city. Antwerp architect Domien de Waghemakere drafted a plan (c. 1540) for a new building in a style typical of the monumental Gothic town halls of Flanders and Brabant. But the threat of war prevented any progress on the project. The building materials intended for the Stadhuis were instead use ...

Charles Batchelor
Charles W. Batchelor (December 25, 1845 – January 1, 1910) was an inventor and close associate of American inventor Thomas Alva Edison during much of Edison's career. He was involved in some of the greatest inventions and technological developments in history. Biographical Information Charles Batchelor was born on Christmas Day, 1845, and raised in Manchester, England. He was a draftsman and machinist, and later on in his life he was Thomas Alva Edison's friend and right-hand man. In 1870, while working for a textile equipment manufacturer, he was sent to the United States to install some equipment in a Newark, New Jersey textile factory. At this time Thomas Edison's main laboratory and shop were also located in Newark where the two met. By the end of October 1871 Batchelor was working at Edison's American Telegraph Works, and by the summer of 1873 was assisting Edison in inventing.

Encyclopaedia Britannica
An encyclopedia (American English) or encyclopædia (British English) is a reference work or compendium providing summaries of knowledge either general or special to a particular field or discipline. Encyclopedias are divided into articles or entries that are arranged alphabetically by article name or by thematic categories, or else are hyperlinked and searchable. Encyclopedia entries are longer and more detailed than those in most dictionaries. Generally speaking, encyclopedia articles focus on '' factual information'' concerning the subject named in the article's title; this is unlike dictionary entries, which focus on linguistic information about words, such as their etymology, meaning, pronunciation, use, and grammatical forms.Béjoint, Henri (2000)''Modern Lexicography'', pp. 30–31. Oxford University Press. Encyclopedias have existed for around 2,000 years and have evolved considerably during that time as regards language (written in a major international or a verna ...
