Philco
Philco (an acronym for Philadelphia Battery Company) is an American electronics industry, electronics manufacturer headquartered in Philadelphia. Philco was a pioneer in battery, radio, and television production. In 1961, the company was purchased by Ford Motor Company, Ford and, from 1966, renamed "Philco-Ford". Ford sold the company to GTE in 1974, and it was purchased by North American Philips, Philips in 1981, which became a subsidiary of the Dutch company Philips in 1987. In North America, the Philco brand is owned by Philips. In other markets, the Philco International brand is owned by Electrolux. In the early 1920s, Philco made storage batteries, "socket power" battery eliminator units (plug-in transformers), and battery chargers. With the invention of the rectifier tube, which made it practical to power radios by electrical outlets, in 1928, Philco entered the radio business. They followed other radio makers such as RCA, Atwater-Kent, Zenith Electronics, Freshman Masterpie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Predicta
The Philco Predicta is a black and white television chassis style, which was made in several cabinet models with 17” or 21” screens by the American company Philco from 1958 to 1960. The Predicta was marketed as the world’s first swivel-screen television. Designed by Catherine Winkler, Severin Jonassen and Richard Whipple, it featured a picture tube (CRT) that separated from the rest of the cabinet. The safety mask on the front of the picture tube was made with a new organic plastic product by Eastman Plastics called “tenite”, which protected the glass and provided implosion protection for the user and produced a greenish tint. The Predicta also had a thinner picture tube than many other televisions at the time, which led it to be marketed as a more futuristic television set. Predicta television sets were constructed with a variety of cabinet configurations, some detachable but all separate from the tube itself and connected by wires. As its manufacturer explained ...

Philo Farnsworth
Philo Taylor Farnsworth (August 19, 1906 – March 11, 1971), "The father of television", was the American inventor and pioneer who was granted the first patent for the television by the United States Government. Burns, R. W. (1998), ''Television: An international history of the formative years''. IET History of Technology Series, 22. LondonThe Institution of Engineering and Technology (IET) p. 370. . He also invented a video camera tube, and the image dissector. He commercially produced and sold a fully functioning television system, complete with receiver and camera—which he produced commercially through the Farnsworth Television and Radio Corporation from 1938 to 1951, in Fort Wayne, Indiana. In later life, Farnsworth invented a small nuclear fusion device, the Farnsworth Fusor, employing inertial electrostatic confinement (IEC). Like many fusion devices, it was not a practical device for generating nuclear power, although it provides a viable source of neutrons. The desi ...

Vacuum Tube Batteries
A generic vacuum_tube.html" ;"title="triode vacuum tube">triode vacuum tube circuit showing "A", "B" and "C" batteries In the early days of electronics, devices that used vacuum tubes (called ''valves'' in British contexts), such as radios, were powered by battery (electricity), batteries. Each battery had a different designation depending on which tube element it was associated with. Initially, the only such device was a diode with only a filament (cathode) and a plate (anode). Following the direction of electron flow, these electrodes are identified as "A" and "B", respectively and thus the associated batteries are referred to as the "A" and "B" batteries respectively. Later, when the control grid element was added to create the triode tube, it was logically assigned the letter "C" and supplied from a "C" battery. Subsequent addition of further internal elements to improve the performance of the triode did not require an extension to this series of batteries – these e ...

Battery Eliminator
An AC adapter or AC/DC adapter (also called a wall charger, power adapter, power brick, or wall wart) is a type of external power supply, often enclosed in a case similar to an AC power plugs and sockets, AC plug. AC adapters deliver electric Electric power, power to devices that lack internal Electronic component, components to draw Alternating current, voltage and power from Mains electricity, mains power themselves. The internal Electrical network, circuitry of an external power supply is often very similar to the design that would be used for a built-in or internal supply. When used with battery (electricity), battery-powered equipment, adapters typically battery charger, charge the battery as well as powering the equipment. Aside from obviating the need for internal power supplies, adapters offer flexibility: a device can draw power from 120 VAC or 230 VAC mains, vehicle battery, or aircraft battery, just by using different adapters. Safety can be another adva ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wife Approval Factor
Wife acceptance factor, wife approval factor, or wife appeal factor (WAF) is an assessment of design elements that either increase or diminish the likelihood a wife will approve the purchase of expensive consumer electronics products such as high fidelity loudspeakers and home theater systems. WAF is a tongue-in-cheek play on electronics jargon such as " form factor" and "power factor" and derives from the stereotype that men are predisposed to appreciate gadgetry and performance criteria whereas women must be wooed by visual and aesthetic factors. The term is considered a sexist term by some people, for example women in the high fidelity hobbyist community, who have stated the sexism in the community is reflected by use of the phrase WAF. Some people have used the non-gender-specific term significant other acceptance parameters (SOAP). History Radio At the start of the golden age of radio in the early 1920s, most radio broadcasters and listeners were men with technical skills ...

Batteryless Radio
A batteryless radio is a type of radio receiver that does not require the use of a battery (electricity), battery to provide it with electrical power. Originally this referred to units which could be used directly by AC mains supply (mains radio); it can also refer to units which do not require a power source at all, except for the power that they receive from an ambient radio source, such as radio waves. History The earliest amplifying radios, vacuum tube radios, used Electric battery, batteries until the mid to late 1920s. The line-operated vacuum tube receiver was invented in 1925 by Edward S. Rogers, Sr. The unit operated with five Rogers vacuum tube#AC power, AC vacuum tubes and the Rogers battery eliminator, Battery-Eliminator Power Unit (power supply). This unit was later marketed for $120 as "Type 120". He established the Toronto station CFRB (an abbreviation of ''Canada's First Rogers Batteryless'') to promote sales of the product. Batteryless radios were not introdu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Philips
Koninklijke Philips N.V. (), simply branded Philips, is a Dutch multinational health technology company that was founded in Eindhoven in 1891. Since 1997, its world headquarters have been situated in Amsterdam, though the Benelux headquarters is still in Eindhoven. The company gained its royal honorary title in 1998. Philips was founded by Gerard Philips and his father Frederik, with their first products being light bulbs. Through the 20th century, it grew into one of the world's largest electronics conglomerates, with global market dominance in products ranging from kitchen appliances and electric shavers to light bulbs, televisions, cassettes, and compact discs (both of which were invented by Philips). At one point, it played a dominant role in the entertainment industry (through PolyGram). However, intense competition from primarily East Asian competitors throughout the 1990s and 2000s led to a period of downsizing, including the divestment of its lighting and c ...
