Charles Francis Jenkins
Charles Francis Jenkins (August 22, 1867 – June 6, 1934) was an American engineer who was a pioneer of early cinema and one of the inventors of television, though he used mechanical rather than electronic technologies. His businesses included Charles Jenkins Laboratories and Jenkins Television Corporation (the corporation being founded in 1928, the year the Laboratories were granted the first commercial television license in the United States). Over 400 patents were issued to Jenkins, many for his inventions related to motion pictures and television . Jenkins was born in Dayton, Ohio, grew up near Richmond, Indiana, where he went to school and went to Washington, D.C. in 1890, where he worked as a stenographer. Motion pictures Jenkins started experimenting with motion pictures in 1891, and eventually quit his job and concentrated fully on the development of his own movie projector, the Phantoscope. As the ''Richmond Telegram'' reported on June 6, 1894, about his en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an sufficiency of disclosure, enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private la ...

Cotton States And International Exposition
Cotton (), first recorded in ancient India, is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus '' Gossypium'' in the mallow family Malvaceae. The fiber is almost pure cellulose, and can contain minor percentages of waxes, fats, pectins, and water. Under natural conditions, the cotton bolls will increase the dispersal of the seeds. The plant is a shrub native to tropical and subtropical regions around the world, including the Americas, Africa, Egypt and India. The greatest diversity of wild cotton species is found in Mexico, followed by Australia and Africa. Cotton was independently domesticated in the Old and New Worlds. The fiber is most often spun into yarn or thread and used to make a soft, breathable, and durable textile. The use of cotton for fabric is known to date to prehistoric times; fragments of cotton fabric dated to the fifth millennium BC have been found in the Indus Valley civilizatio ...

Thomas Armat
Thomas J. Armat (October 25, 1866 – September 30, 1948) was an American mechanic and inventor, a pioneer of cinema best known through the co-invention of the Edison Vita Armat studied at the Mechanics Institute in Richmond, Virginia and then in 1894 at the Bliss Electrical School in Washington, D.C., where he met Charles Francis Jenkins. The two classmates teamed up to develop a movie projector using a new kind of intermittent motion mechanism, a "beater mechanism" similar to the one patented 1893 by Georges Demenÿ in France. It was one of the first projectors using what is known as the Latham loop (an extra loop of the film before the transport mechanism to reduce the tension on the film and avoid film breakage, developed independently at the same time by Woodville Latham and his sons). They made their first public projection using their invention, named '' Phantoscope'' after an earlier model designed by Jenkins alone, in September 1895 at the Cotton States and Internati ...

Phonograph
A phonograph, later called a gramophone, and since the 1940s a record player, or more recently a turntable, is a device for the mechanical and analogue reproduction of sound. The sound vibration Waveform, waveforms are recorded as corresponding physical deviations of a helical or spiral groove engraved, etched, incised, or impressed into the surface of a rotating cylinder or disc, called a ''Phonograph record, record''. To recreate the sound, the surface is similarly rotated while a playback #Stylus, stylus traces the groove and is therefore vibrated by it, faintly reproducing the recorded sound. In early acoustic phonographs, the stylus vibrated a Diaphragm (acoustics), diaphragm that produced sound waves coupled to the open air through a flaring Horn loudspeaker, horn, or directly to the listener's ears through stethoscope-type earphones. The phonograph was invented in 1877 by Thomas Edison; its use would rise the following year. Alexander Graham Bell's Volta Laboratory an ...

Shot Put
The shot put is a track-and-field event involving "putting" (throwing) a heavy spherical Ball (sports), ball—the ''shot''—as far as possible. For men, the sport has been a part of the Olympic Games, modern Olympics since their 1896 Summer Olympics, revival (1896), and women's competition began in 1948 Summer Olympics, 1948. The shot put is part of the most common Combined track and field events, combined events, the decathlon, the Women's Heptathlon, women's and men's heptathlon and the women's pentathlon. History Homer mentions competitions of rock throwing by soldiers during the Trojan War, siege of Troy but there is no record of any weights being thrown in Greek competitions. The first evidence for Stone put, stone- or weight-throwing events were in the Scottish Highlands, and date back to approximately the first century. In the 16th century Henry VIII of England, King Henry VIII was noted for his prowess in court competitions of weight and hammer throwing. The first eve ...

Chronophotography
Chronophotography is a photographic technique from the Victorian era which captures a number of phases of movements. The best known chronophotography works were mostly intended for the scientific study of Animal locomotion, locomotion, to discover practical information for animal handlers and/or as reference material for artists. Although many results were not intended to be exhibited as moving pictures, there is much overlap with the more or less simultaneous quest to register and exhibit photographic motion pictures. Definition Chronophotography is defined as "a set of photographs of a moving object, taken for the purpose of recording and exhibiting successive phases of motion". The term ''chronophotography'' was coined by French physiologist Étienne-Jules Marey to describe photographs of movement from which measurements could be taken and motion could be studied. It is derived from the Greek word χρόνος ''chronos, chrónos'' ("time") combined with ''photography''.The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zoopraxiscope
The zoopraxiscope (initially named ''zoographiscope'' and ''zoogyroscope'') is an early device for displaying moving images and is considered an important predecessor of the movie projector. It was conceived by photographic pioneer Eadweard Muybridge in 1879 (and built for him by January 1880 to project his famous chronophotographic pictures in motion and thus prove that these were authentic). Muybridge used the projector in his public lectures from 1880 to 1895. The projector used 16" glass disks onto which Muybridge had an unidentified artist paint the sequences as silhouettes. This technique eliminated the backgrounds and enabled the creation of fanciful combinations and additional imaginary elements. Only one disk used photographic images, of a horse skeleton posed in different positions. A later series of 12″ discs, made in 1892–1894, used outlines drawn by Erwin F. Faber that were printed onto the discs photographically, then colored by hand. These colored discs we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magic Lantern
The magic lantern, also known by its Latin name , is an early type of image projector that uses pictures—paintings, prints, or photographs—on transparent plates (usually made of glass), one or more lens (optics), lenses, and a light source. Because a single lens inverts an image projected through it (as in the phenomenon which inverts the image of a camera obscura), slides are inserted upside down in the magic lantern, rendering the projected image correctly oriented. It was mostly developed in the 17th century and commonly used for entertainment purposes. It was increasingly used for education during the 19th century. Since the late 19th century, smaller versions were also mass-produced as toys. The magic lantern was in wide use from the 18th century until the mid-20th century when it was superseded by a compact version that could hold many 35 mm photographic slides: the slide projector. Technology Apparatus The magic lantern used a concave mirror behind a light so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
