Mazda (light Bulb)
Mazda was a trademarked name registered by General Electric (GE) in 1909 for incandescent light bulbs. The name was used from 1909 to 1945 in the United States by GE and Westinghouse. Mazda brand light bulbs were made for decades after 1945 outside the US. The company chose the name due to its association with Ahura Mazda, the transcendental and universal God of Zoroastrianism whose name means light of wisdom in the Avestan language. In 1909 the Mazda name was created for the tungsten filament light bulb. GE sold bulbs under this trademark starting in 1909. GE promoted the mark as identifying tungsten filament bulbs with predictable performance and life expectancy. GE also licensed the Mazda name, socket sizes, and tungsten filament technology to other manufacturers to establish a standard for lighting. Bulbs were soon sold by many manufacturers with the Mazda name licensed from GE, including British Thomson-Houston in the United Kingdom, Toshiba in Japan, and GE's chief compe ...

Northeast Minneapolis
Northeast is a defined community in the U.S. city of Minneapolis that is composed of 13 smaller neighborhoods whose street addresses end in "NE". Unofficially it also includes the neighborhoods of the University community which have "NE" addresses, and the entirety of the Old Saint Anthony business district, which sits on the dividing line of "NE" and "SE" addresses. In the wider community, this business district, which is the oldest settlement in the city, is often identified as the heart of Northeast, in part because it lies across the Mississippi River from Downtown Minneapolis. Northeast is sometimes referred to as "Nordeast", reflecting the history of northern and eastern European immigrants and their language influence. The modern community includes commercial districts stretching along the major corridors of University Avenue, Central Avenue, East Hennepin Avenue, Broadway Street, and Stinson and New Brighton Boulevards towards the city limits.

Lighting Brands
Lighting or illumination is the deliberate use of light to achieve practical or aesthetic effects. Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight. Daylighting (using windows, skylights, or light shelves) is sometimes used as the main source of light during daytime in buildings. This can save energy in place of using artificial lighting, which represents a major component of energy consumption in buildings. Proper lighting can enhance task performance, improve the appearance of an area, or have positive psychological effects on occupants. Indoor lighting is usually accomplished using light fixtures, and is a key part of interior design. Lighting can also be an intrinsic component of landscaping, landscape projects. History With the Control of fire by early humans, discovery of fire, the earliest form of artificial lighting used to illuminate an area were campfires or torches. As ...

Maxfield Parrish
Maxfield Parrish (July 25, 1870 – March 30, 1966) was an American painter and illustration, illustrator active in the first half of the 20th century. He is known for his distinctive saturated hues and idealized neo-classical imagery. His career spanned fifty years and was wildly successful: the National Museum of American Illustration deemed his painting ''Daybreak (painting), Daybreak'' (1922) to be the most successful art print of the 20th century. Early life and education Maxfield Parrish was born in Philadelphia, Pennsylvania, to painter and etcher Stephen Parrish and Elizabeth Bancroft. His given name was Frederick Parrish, but he later adopted Maxfield, his paternal grandmother's maiden name, as his middle, then finally as his professional name. He was raised in a Quaker society. As a child he began drawing for his own amusement, showed talent, and his parents encouraged him. Between 1884 and 1886, his parents took Parrish to Europe, where he toured England, Italy, ...

Edison Screw
Edison screw (ES) is a standard lightbulb socket for electric light bulbs. It was developed by Thomas Edison (1847–1931), patented in 1881, and was licensed in 1909 under General Electric's Mazda trademark. The bulbs have right-hand threaded metal bases (caps) which screw into matching threaded sockets (lamp holders). For bulbs powered by AC current, the thread is generally connected to neutral and the contact on the bottom tip of the base is connected to the "live" phase. In North America and continental Europe, Edison screws displaced other socket types for general lighting. In the early days of electrification, Edison screws were the only standard connector, and appliances other than light bulbs were connected to AC power via lamp sockets. Today Edison screw sockets comply with international standards. History In the United States, early manufacturers of incandescent lamps used several different and incompatible bases in the 1880s and 1890s. In designing his screw, Edis ...

Vitold Belevitch
Vitold Belevitch (2 March 1921 – 26 December 1999) was a Belgian mathematician and electrical engineer of Russian origin who produced some important work in the field of electrical network theory. Born to parents fleeing the Bolsheviks, he settled in Belgium where he worked on early computer construction projects. Belevitch is responsible for a number of circuit theorems and introduced the now well-known scattering parameters. Belevitch had an interest in languages and found a mathematical derivation of Zipf's law. He also published on machine languages. Another field of interest was transmission lines, where he published on line coupling. He worked on telephone conferencing and introduced the mathematical construct of the conference matrix. Early life Belevitch was born 2 March 1921 in Terijoki, Karelia, now incorporated into Russia, but at the time part of Finland. Belevitch's parents were Russian and his mother was an ethnic Pole. They were attempting to flee from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compagnie Industrielle Française Des Tubes Electroniques
La Compagnie des Lampes ("The Lamp Company") was a name used by several French companies all in the area of electrical products particularly lighting. La Compagnie des Lampes (1888) The original ''Compagnie des Lampes'' was set up at Ivry-sur-Seine in 1888. The plant was subsequently attached to the CGE (Compagnie Générale d'Electricité) on its acquisition in 1898. The plant is classified as a historical monument. In 1915, the plant was the second to start manufacturing ''TM'' triodes ("Télégraphie Militaire") in France, under their ''Métal'' brand (the first was E.C.&A. Grammont (Lyon) under their ''Radio Fotos'' brand). Later they made tubes for domestic AC transformer heating such as thBW604anBW1010under their ''Métal- Secteur'' brand.

Vacuum Tube
A vacuum tube, electron tube, valve (British usage), or tube (North America), is a device that controls electric current flow in a high vacuum between electrodes to which an electric voltage, potential difference has been applied. The type known as a thermionic tube or thermionic valve utilizes thermionic emission of electrons from a hot cathode for fundamental electronic functions such as signal amplifier, amplification and current rectifier, rectification. Non-thermionic types such as a vacuum phototube, however, achieve electron emission through the photoelectric effect, and are used for such purposes as the detection of light intensities. In both types, the electrons are accelerated from the cathode to the anode by the electric field in the tube. The simplest vacuum tube, the diode (i.e. Fleming valve), invented in 1904 by John Ambrose Fleming, contains only a heated electron-emitting cathode and an anode. Electrons can only flow in one direction through the device—fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
