Teldec
Teldec (Telefunken-Decca Schallplatten GmbH) is a German record label in Hamburg, Germany. Today the label is a property of Warner Music Group. History Teldec was a producer of (first) shellac and (later) vinyl records. The Teldec manufacturing facility was located in Nortorf near Kiel in Germany. The company was founded in 1950 as a co-operation between Telefunken and Decca Records. The name Teldec is the result of taking the first three letters of both labels: Telefunken and Decca. Records manufactured by Teldec mostly were released under the Telefunken or Decca label, but normally these records contained no hint that they were made by Teldec. In 1983, Telefunken and Decca pulled out of Teldec and in 1987 Teldec was sold to Time Warner. In 1997, the remaining compact-disc production facility in Nortorf was to be closed by Time Warner, but after a management buyout, the new company OK Media, continued CD production. In 2001, after the merger of AOL & Time Warner, Teldec closed. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Georg Von Arco
Georg Wilhelm Alexander Hans Graf von Arco (30 August 1869 in Großgorschütz – 5 May 1940 in Berlin) was a German physicist, radio pioneer, and one of the joint founders of the "''Society for Wireless Telegraphy''" which became the Telefunken company. He was an engineer and the technical director of Telefunken. He was crucial in the development of wireless technology in Europe. Arco served for a time as an assistant to Adolf Slaby, who was close to William II, German Emperor. Until 1930, Arco was one of the two managing directors of the company. He participated in the development of high performance tube transmitters. Together with his teacher, Slaby, he was considerably involved in the study and development of high-frequency engineering in Germany. He was a Monist and a pacifist. Between 1921-22, he was a chairman of the German Monist Federation. Early years Arco was born on the estate of his father, Count Alexander Karl von Arco, in Großgorschütz, Upper Silesia, Pr ...

Adolf Slaby
Adolf Karl Heinrich Slaby (18 April 1849 – 6 April 1913) was a German electronics pioneer and the first Professor of electro-technology at the Technical University of Berlin (1886). Education Slaby was born in Berlin, the son of a bookbinder. He studied at the Berlin Trade Academy, the predecessor of Berlin-Charlottenburg Technical Academy to study mechanical engineering and mathematics under Franz Reuleaux. He was employed as a housekeeper with the machine manufacturer Louis Schwartzkopff, leading to an interest in mechanical engineering. Slaby continued his studies at the University of Jena, and received his doctorate in mathematics. Early research Slaby taught mathematics and mechanics at a vocational school at Potsdam, where he conducted experiments on steam engines and petrol engines. He wrote his book ''Theorie der Gasmaschinen'' (Theory of Gas Engines), which had an important part in the development of Internal combustion engines. Slaby also studied with Heinrich ...

Karl Ferdinand Braun
Karl Ferdinand Braun (; 6 June 1850 – 20 April 1918) was a German electrical engineer, inventor, physicist and Nobel laureate in physics. Braun contributed significantly to the development of radio and television technology: he shared the 1909 Nobel Prize in Physics with Guglielmo Marconi "for their contributions to the development of wireless telegraphy", was a founder of Telefunken, one of the pioneering communications and television companies, and has been both called the "father of television" (shared with inventors like Paul Gottlieb Nipkow) and the co-father of the radio telegraphy, together with Marconi. Biography Braun was born in Fulda, Germany, and educated at the University of Marburg and received a PhD from the University of Berlin in 1872. In 1874, he discovered that a point-contact metal–semiconductor junction rectifies alternating current. He became director of the Physical Institute and professor of physics at the University of Strassburg in 1895. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telefunken Kompass Sender
The Telefunken Kompass Sender was one of the earliest radio navigation systems to be deployed. It was developed in 1908 by the German electronics firm Telefunken. It was used primarily for long-distance navigation by Zeppelins, and was taken out of service around 1918. The system consisted of a series of 32 individual 60 m long cables supported in the center by a single mast and reaching the ground at their ends, forming a sort of umbrella-shaped device. Pairs of cables were wired to each other to form a series of sixteen 120 m long dipole antennas, now known as inverted-V antennas. The transmitter was first connected to all sixteen antennas and sent the morse code identifier for the station. After the identifier was sent and a specific time interval had passed, the system started switching on individual dipoles in order around the station. An aircraft located at some distance from the station would first listen for the identifier, and then when the time delay expired, s ...

Radio Navigation
Radio navigation or radionavigation is the application of radio frequencies to determine a position of an object on the Earth, either the vessel or an obstruction. Like radiolocation, it is a type of radiodetermination. The basic principles are measurements from/to electric beacons, especially * Angular directions, e.g. by bearing, radio phases or interferometry, * Distances, e.g. ranging by measurement of time of flight between one transmitter and multiple receivers or vice versa, * Distance ''differences'' by measurement of times of arrival of signals from one transmitter to multiple receivers or vice versa * Partly also velocity, e.g. by means of radio Doppler shift. Combinations of these measurement principles also are important—e.g., many radars measure range and azimuth of a target. Bearing-measurement systems These systems used some form of directional radio antenna to determine the location of a broadcast station on the ground. Conventional navigation techni ...

Zeppelin
A Zeppelin is a type of rigid airship named after the German inventor Count Ferdinand von Zeppelin () who pioneered rigid airship development at the beginning of the 20th century. Zeppelin's notions were first formulated in 1874Eckener 1938, pp. 155–157. and developed in detail in 1893.Dooley 2004, p. A.187. They were patented in Germany in 1895 and in the United States in 1899. After the outstanding success of the Zeppelin design, the word ''zeppelin'' came to be commonly used to refer to all rigid airships. Zeppelins were first flown commercially in 1910 by Deutsche Luftschiffahrts-AG (DELAG), the world's first airline in revenue service. By mid-1914, DELAG had carried over 10,000 fare-paying passengers on over 1,500 flights. During World War I, the German military made extensive use of Zeppelins as bombers and as scouts, resulting in over 500 deaths in bombing raids in Britain. The defeat of Germany in 1918 temporarily slowed the airship business. Although DELAG establi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
