Frederick A. Kolster
Frederick A. Kolster (January 13, 1883 – 1950) was a Swiss-born United States electrical engineer and inventor. He set up the Kolster Radio Corporation. Career Kolster worked at the National Bureau of Standards from 1911 to 1921. While at the NBS, he pioneered a number of developments in radio signal detection and radio compass work, including the Kolster Decremeter. In 1913, he convinced the Bureau of Lighthouses to install radio beacons at all important lighthouses and light ships. Kolster also patented in 1915 a radio direction finder, used in the subsequent World War I by U.S. destroyers at sea to locate German submarines. In 1921, he left the National Bureau of Standards to join the Federal Telegraph Company as chief research engineer, as part of the company's bid to commercialize the radio compass technology to ships. Products manufactured under his research name came under the Federal-Brandes name (after November 1926). The commercial efforts failed, however, and the ...

Kolster Radio Corporation
The Kolster Radio Corporation was an electronics manufacturer and distributor based in Newark, New Jersey, which went bankrupt in January 1930. It bore the name of its chief research engineer, Frederick A. Kolster. In June 1928, the Columbia Phonograph Company announced plans to market a radio receiving set built by Kolster Radio. The product was sold in the United States, Europe, and Japan. Insolvency Three receivers were appointed on January 21, 1930, to handle the failure of the company, which was located at 200 Mount Prospect Avenue in Newark. The business possessed considerably more assets than liabilities. However, because of overproduction, it suffered an inability to raise cash to fulfill its immediate obligations.''Receivers Are Named For Kolster Radio'', New York Times, January 22, 1930, pg. 31. Under a plan approved by receivers, the Kolster plant in Newark reopened after March 1930. The production facility fulfilled the completion of 15,000 partly built radio sets ...

National Bureau Of Standards
The National Institute of Standards and Technology (NIST) is an agency of the United States Department of Commerce whose mission is to promote American innovation and industrial competitiveness. NIST's activities are organized into physical science laboratory programs that include nanoscale science and technology, engineering, information technology, neutron research, material measurement, and physical measurement. From 1901 to 1988, the agency was named the National Bureau of Standards. History Background The Articles of Confederation, ratified by the colonies in 1781, provided: The United States in Congress assembled shall also have the sole and exclusive right and power of regulating the alloy and value of coin struck by their own authority, or by that of the respective states—fixing the standards of weights and measures throughout the United States.

Federal Telegraph Company
The Federal Telegraph Company was a United States manufacturing and communications company that played a pivotal role in the 20th century in the development of radio communications. Founded in Palo Alto, California in 1909 by Cyril Frank Elwell, the company would eventually merge in August 1927 with the Mackay Companies. In 1911-13, Lee De Forest and two assistants worked at FTC on the first vacuum tube amplifier and oscillator, which De Forest called the "Oscillaton" after his earlier Audion. The company remained a separate entity within the Mackay Companies, however, and when International Telephone and Telegraph (ITT) purchased the Mackay Companies in 1928 Federal remained a component of the Mackay structure as a manufacturing entity. In 1931, Dr. Ernest O. Lawrence, inventor of the cyclotron, convinced Federal Telegraph to donate an 80-ton magnet they had developed for a canceled project in China to his first cyclotron project on the campus of the University of Californi ...

Radio Pioneers
Radio is the technology of signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver. Radio is very widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like aircraft, ships, spacecraft an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Radio In The United States
Radio broadcasting in the United States has been used since the early 1920s to distribute news and entertainment to a national audience. In 1923, 1 percent of U.S. households owned at least one radio receiver, while a majority did by 1931 and 75 percent did by 1937. It was the first electronic "mass medium" technology, and its introduction, along with the subsequent development of sound films, ended the print monopoly of mass media. During the Golden Age of Radio it had a major cultural and financial impact on the country. However, the rise of television broadcasting in the 1950s relegated radio to a secondary status, as much of its programming and audience shifted to the new "sight joined with sound" service. Originally the term "radio" only included transmissions freely received over-the-air, such as the AM and FM bands, now commonly called "terrestrial radio". However, the term has evolved to more broadly refer to streaming audio services in general, including subscription satel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
