Harry Grindell Matthews
Harry Grindell Matthews (17 March 1880 – 11 September 1941) was an English inventor who claimed to have invented a death ray in the 1920s. Earlier life and inventions Harry Grindell Matthews was born on 17 March 1880 in Winterbourne, Gloucestershire. He studied at the Merchant Venturers' School in Bristol and became an electronic engineer. During the Second Boer War he served in the South African Constabulary and was twice wounded. In 1911 Matthews said he had invented an Aerophone device, a radiotelephone, and transmitted messages between a ground station and an aeroplane from a distance of two miles. His experiments attracted government attention and on 4 July 1912 he visited Buckingham Palace. However, when the British Admiralty requested a demonstration of the Aerophone, Matthews demanded that no experts be present at the scene. When four of the observers dismantled part of the apparatus before the demonstration began and took notes, Matthews cancelled the demonstra ...

The modern village is largely built on top of a hill, with woodlands and fields encompassing it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Remote Control
In electronics, a remote control (also known as a remote or clicker) is an electronic device used to operate another device from a distance, usually wirelessly. In consumer electronics, a remote control can be used to operate devices such as a television set, DVD player or other home appliance. A remote control can allow operation of devices that are out of convenient reach for direct operation of controls. They function best when used from a short distance. This is primarily a convenience feature for the user. In some cases, remote controls allow a person to operate a device that they otherwise would not be able to reach, as when a garage door opener is triggered from outside. Early television remote controls (1956–1977) used ultrasonic tones. Present-day remote controls are commonly consumer infrared devices which send digitally-coded pulses of infrared radiation. They control functions such as power, volume, channels, playback, track change, heat, fan speed, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gunpowder
Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, carbon (in the form of charcoal) and potassium nitrate (saltpeter). The sulfur and carbon act as fuels while the saltpeter is an oxidizer. Gunpowder has been widely used as a propellant in firearms, artillery, rocketry, and pyrotechnics, including use as a blasting agent for explosives in quarrying, mining, building pipelines and road building. Gunpowder is classified as a low explosive because of its relatively slow decomposition rate and consequently low brisance. Low explosives deflagrate (i.e., burn at subsonic speeds), whereas high explosives detonate, producing a supersonic shockwave. Ignition of gunpowder packed behind a projectile generates enough pressure to force the shot from the muzzle at high speed, but usually not enough force to rupture the gun barrel. It thus makes a good propellant but is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The New York Times
''The New York Times'' (''the Times'', ''NYT'', or the Gray Lady) is a daily newspaper based in New York City with a worldwide readership reported in 2020 to comprise a declining 840,000 paid print subscribers, and a growing 6 million paid digital subscribers. It also is a producer of popular podcasts such as '' The Daily''. Founded in 1851 by Henry Jarvis Raymond and George Jones, it was initially published by Raymond, Jones & Company.

Ignition Magneto
An ignition magneto, or high-tension magneto, is a magneto that provides current for the ignition system of a spark-ignition engine, such as a petrol engine. It produces pulses of high voltage for the spark plugs. The older term ''tension'' means ''voltage''. The use of ignition magnetos is now confined mainly to engines where there is no other available electrical supply, for example in lawnmowers and chainsaws. It is also widely used in aviation piston engines even though an electrical supply is usually available. In this case, the magneto's self-powered operation is considered to offer increased reliability; in theory, the magneto should continue operation as long as the engine is turning. History Firing the gap of a spark plug, particularly in the combustion chamber of a high-compression engine, requires a greater voltage (or ''higher tension'') than can be achieved by a simple magneto. The ''high-tension magneto'' combines an alternating current magneto generat ... [...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 Theatr ...

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, impr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photokinema
''Photo-Kinema'' (some sources say ''Phono-Kinema'') was a sound-on-disc system for motion pictures invented by Orlando Kellum. 1921 introduction The system was first used for a small number of short films, mostly made in 1921. These films presented subjects such as actor Frederick Warde reading an original poem "A Sunset Reverie", labor leader Samuel Gompers speaking on labor issues, Judge Ben Lindsey on the need for a separate juvenile court system, Irvin S. Cobb reading from his works, and a lecture by James J. Davis, Secretary of Labor in the Harding administration. Kellum also filmed musical numbers, including a performance of the song "De Ducks" by African American musicians F. E. Miller and Aubrey Lyles who wrote the book for the musical '' Shuffle Along'' (1921), and ''The Famous Van Eps Trio in a Bit of Jazz'' (1921), featuring Fred Van Eps, father of musician George Van Eps. A filmed performance by Sir Harry Lauder made in Phono-Kinema is preserved at the UCLA Fil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
