Tri-Ergon
The Tri-Ergon sound-on-film system was developed from around 1919 by three German inventors, Josef Engl (1893–1942), Joseph Massolle (1889–1957), and Hans Vogt (1890–1979). The system used a photoelectric recording method and a non-standard film size (42mm) which incorporated the sound track with stock 35mm film. With a Swiss backer, the inventors formed Tri-Ergon AG in Zurich, and tried to interest the market with their invention. Ufa acquired the German sound film rights for the Tri-Ergon process in 1925, but dropped the system when the public showing of their first sound film suffered technical failures. The Tri-Ergon system appeared at a time when a number of other sound film processes were arriving on the market, and the company soon merged with a number of competitors to form the Tobis syndicate in 1928, joined by the Klangfilm AG syndicate in 1929 and renamed as Tobis-Klangfilm by 1930. While Tri-Ergon became the dominant sound film process in Germany and much of E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phonofilm
Phonofilm is an optical sound-on-film system developed by inventors Lee de Forest and Theodore Case in the early 1920s. Introduction In 1919 and 1920, Lee De Forest, inventor of the audion tube, filed his first patents on a sound-on-film process, DeForest Phonofilm, which recorded sound directly onto film as parallel lines. These parallel lines photographically recorded electrical waveforms from a microphone, which were translated back into sound waves when the movie was projected. Some sources say that DeForest improved on the work of Finnish inventor Eric Tigerstedt — who was granted German patent 309.536 on 28 July 1914 for his sound-on-film work — and on the Tri-Ergon Exchange, patented in 1919 by German inventors Josef Engl, Hans Vogt, and Joseph Massole. The Phonofilm system, which recorded synchronized sound directly onto film, was used to record vaudeville acts, musical numbers, political speeches, and opera singers. The quality of Phonofilm was poor at first, improved ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sound-on-film
Sound-on-film is a class of sound film processes where the sound accompanying a picture is recorded on photographic film, usually, but not always, the same strip of film carrying the picture. Sound-on-film processes can either record an analog sound track or digital sound track, and may record the signal either optically or magnetically. Earlier technologies were sound-on-disc, meaning the film's soundtrack would be on a separate phonograph record. History Sound on film can be dated back to the early 1880s, when Charles E. Fritts filed a patent claiming the idea. In 1923 a patent was filed by E. E. Ries, for a variable density soundtrack recording, which was submitted to the SMPE (now SMPTE), which used the mercury vapor lamp as a modulating device to create a variable-density soundtrack. Later, Case Laboratories and Lee De Forest attempted to commercialize this process, when they developed an Aeolite glow lamp, which was deployed at Movietone Newsreel at the Roxy Theatre ...

UFA GmbH
UFA GmbH, shortened to UFA (), is a film and television production company that unites all production activities of the media conglomerate Bertelsmann in Germany. Its name derives from Universum-Film Aktiengesellschaft (normally abbreviated as ''UFA''), a major German film company headquartered in Babelsberg, producing and distributing motion pictures from 1917 until the end of the Nazi era. The name UFA was revived by Bertelsmann for an otherwise unrelated film and television outfit, UFA GmbH. The original UFA was established as Universum-Film Aktiengesellschaft on December 18, 1917, as a direct response to foreign competition in film and propaganda. UFA was founded by a consortium headed by Emil Georg von Stauß, a former Deutsche Bank board member. In March 1927, Alfred Hugenberg, an influential German media entrepreneur and later Minister of the Economy, Agriculture and Nutrition in Hitler's cabinet, purchased UFA and transferred ownership of it to the Nazi Party in 1933. ...

Tobis Film
Tobis Film was a German film production and film distribution company. Founded in the late 1920s as a merger of several companies involved in the switch from silent to sound films, the organisation emerged as a leading German sound studio. Tobis used the Tri-Ergon sound-on-film system under the Tobis-Klang trade name. The Ufa production company had separate rights to the Tobis system, which it used under the trade name of Ufa-Klang. Some Tobis films were released in Germany by the subsidiary Europa Film. Its principal production studios were the Johannisthal Studios in Berlin. During the Nazi era, Tobis was one of the four major film companies along with Terra Film, Bavaria Film and UFA. In 1942 all these companies were merged into a single state-controlled industry bringing an end to Tobis' independent existence, though films continued to be released under the Tobis banner. International operations From 1933 until 1938, Tobis controlled the dominant Austrian producer Sascha- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lee De Forest
Lee de Forest (August 26, 1873 – June 30, 1961) was an American inventor and a fundamentally important early pioneer in electronics. He invented the first electronic device for controlling current flow; the three-element "Audion" triode vacuum tube in 1906. This started the Electronic Age, and enabled the development of the electronic amplifier and oscillator. These made radio broadcasting and long distance telephone lines possible, and led to the development of talking motion pictures, among countless other applications. He had over 300 patents worldwide, but also a tumultuous career— he boasted that he made, then lost, four fortunes. He was also involved in several major patent lawsuits, spent a substantial part of his income on legal bills, and was even tried (and acquitted) for mail fraud. Despite this, he was recognised for his pioneering work with the 1922 IEEE Medal of Honor, the 1923 Franklin Institute Elliott Cresson Medal and the 1946 American Institute of ...

William Fox (producer)
Wilhelm Fried Fuchs ( hu, Fried Vilmos; January 1, 1879 – May 8, 1952), commonly and better known as William Fox, was a Hungarian-American film industry executive who founded the Fox Film Corporation in 1915 and the Fox West Coast Theatres chain in the 1920s. Although he lost control of his film businesses in 1930, his name was used by 20th Century Fox (now ''20th Century Studios'') and continues to be used in the trademarks of the present-day Fox Corporation, including the Fox Broadcasting Company, Fox News, Fox Sports and Foxtel. Early life Fox was born in Tolcsva, Hungary, and originally named Wilhelm Fried Fuchs. His parents, Michael Fuchs and Anna Fried, were both Hungarian Jews. The family immigrated to the United States when William was nine months old and settled in New York City, where they had twelve more children, of whom only six survived. With his family largely destitute, William found himself as a youth forced to sell candy in Central Park, work as a newsboy, ...

Fox Film Corporation
The Fox Film Corporation (also known as Fox Studios) was an American Independent film production studio formed by William Fox (1879–1952) in 1915, by combining his earlier Greater New York Film Rental Company and Box Office Attractions Film Company (founded 1913). The company's first film studios were set up in Fort Lee, New Jersey, but in 1917, William Fox sent Sol M. Wurtzel to Hollywood, California to oversee the studio's new West Coast production facilities, where the climate was more hospitable for filmmaking. On July 23, 1926, the company bought the patents of the Movietone sound system for recording sound onto film. After the Wall Street crash of 1929, William Fox lost control of the company in 1930, during a hostile takeover. Under new president Sidney Kent, the new owners began conversations of a fusion with Twentieth Century Pictures, under founders Joseph M. Schenck and his friend Darryl Zanuck. Schenck, Zanuck, and Spyros Skouras merged the Fox Studios with T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrostatic Loudspeaker
An electrostatic loudspeaker (ESL) is a loudspeaker design in which sound is generated by the force exerted on a membrane suspended in an electrostatic field. Design and functionality The speakers use a thin flat diaphragm usually consisting of a plastic sheet coated with a conductive material such as graphite sandwiched between two electrically conductive grids, with a small air gap between the diaphragm and grids. For low distortion operation, the diaphragm must operate with a constant charge on its surface, rather than with a constant voltage. This is accomplished by either or both of two techniques: the diaphragm's conductive coating is chosen and applied in a manner to give it a very high surface resistivity, and/or a large value resistor is placed in series between the EHT (Extra High Tension or Voltage) power supply and the diaphragm (resistor not shown in the diagram here). However, the latter technique will still allow distortion as the charge will migrate across the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deutsches Museum
The Deutsches Museum (''German Museum'', officially (English: ''German Museum of Masterpieces of Science and Technology'')) in Munich, Germany, is the world's largest museum of science and technology, with about 28,000 exhibited objects from 50 fields of science and technology. It receives about 1.5 million visitors per year. The museum was founded on 28 June 1903, at a meeting of the Association of German Engineers (VDI) as an initiative of Oskar von Miller. It is the largest museum in Munich. For a period of time the museum was also used to host pop and rock concerts including The Who, Jimi Hendrix and Elton John. Museumsinsel The main site of the Deutsches Museum is a small island in the Isar river, which had been used for rafting wood since the Middle Ages. The island did not have any buildings before 1772 because it was regularly flooded prior to the building of the Sylvensteinspeicher. In 1772 the Isar barracks were built on the island and, after the flooding of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
