Tung-Sol
[11] In 1935, Clyde C. Bohner was vice-president in Charge of Engineering and discussed information on radio tubes with a company magazine sold to the public, such as an article, titled, "How to Get the Best That's on the Air at Home and Abroad.
[14] Circa 1948, there was a picture of the Tung-Sol Factory at the corner of High Street and Eighth Avenue by Thomas Pallante located in the Newark Public Library.
[18] In time they established themselves as leaders in the development and production of vacuum tubes, with their main competition including RCA and Sylvania.
[24] An unclassified letter from MIT Lincoln Laboratory of the Office of Naval Research was sent to C. F. (typographical error) Coon on April 21, 1949, by E. S. Rich with subject matter about Life Tests on 5687 Tubes.
[30] The Bloomfield plant hired engineers to study circuitry problems involving the use of electron tubes and semiconductor devices; in the applications laboratory.
[32] In 1953, Tung-Sol Lamp Works, Inc. was listed as a participating member of the Armed Forces Communications Association, an organization needed for national security with employees or officials in electronics to advise and assist with various aspects such as manufacturing or procurement.
[36] The Chatham Electronics, Newark, New Jersey subsidiary was listed in the May 11, 1951 Federal Register as contractor for Department of the Army products with contracts: DA-28-043-SC—5422, DA-36-039-SC-6665, DA-36-039—SC-7309, DA-36-039-SC-8411, DA-49-170-SC-21, and NObr 52059.
Tung-Sol started transistor research in 1953 with engineering samples and delayed introduction as vacuum tube production were large and popular business.
[40] This year also marks Tung-Sols interest to increase TV tube output production with new shares of stock being issued for capital.
[44] Tung-Sol began in 1958, to make transistors in transitioning its operations from vacuum tube manufacturing to solid-state components with lacking in mastery process.
The master list directory indicated the manufacturers addresses for technicians to service or search component parts, replacement products, equipment, material and instruments, or technical publications.
[50] The sales department had designer agency: E.M. Freystadt Associates, Inc. in New York to produce advertisements in Tele-Tech issue of August 1954 with vacuum tube drawings and information.
[53] About June 1959, Neil Uptegrove was appointed manager of advertising and sales promotion for Tung-Sol Electric Inc., according to the July 1959 publication, Electronics World Radio and TV news.
[65] In 1962, The New York Times published on August 30, 1962, that Tung-Sol Electric, Inc. planned to close a Washington tube plant and transfer operations to Weatherly.
[66] About 1962 or 1963, the East Orange transistor plant and cathrode ray operations had closed and caused excess costs towards half-year profits.
[70] In 1964, there was a labor arbitration case brought into the court over improper seniority dates between United Electrical Workers, Local 512, and Tung-Sol of Canada Ltd. during a strike.
Thursday, August 28, 1980, reported in the Daily Times, that Wagner would cease October 1, 1980 the Bramalea plant production of sealed beams.
On January 22, plans to merge with Wagner cause both stocks to rise in price and the directors of both companies agreed on March 4 to the merger.
[81] In May 1985, a worldwide manufacturing company called Cooper Industries, performed a friendly takeover of the former Wagner plants for $1.1 billion, including debt of $300 million.
[82] His past responsibilities in the Chatham/Tung-Sol lead him to Board of Directors for several companies such as Varian Associations (early vacuum tubes, analytical equipment and semiconductor manufacturing equipment), Control Data Corporation, Dresser Industries (a manufacturer of actuators, valves, meters, instruments, regulators, switches), Sybron Corporation, Indresco, and Berg Electronics (board-to-board, wire-to-board, and cable-to-board connectors, sockets, fiber optic interconnects, internal and external cable assemblies.
[84] In 2003, Federal-Mogul planned to shutdown a plant at Copeland Industrial Park in Hampton, Virginia and lay off 260 workers, some were "lamp makers," technicians, and quality-control staff.
[86] There was a Federal-Mogul mailing address for a location in Weatherly as 75 West Main Street and Google maps dated August 2009 revealed vacant land.
[88] On March 10, 2016, the Weatherly Borough Council was selling some part of the Tung-Sol land for a grocery store development after no historical details on the status of plant closure by Federal-Mogul ownership.
In November, Chatham Electronics common stock was acquired for $1.5 million in notes and $500,000 in cash to be owned by Gera Corporation.
[117] Tung Sol Electric, Inc., of Newark was one supplier that produced electron tubes for the IBM 701 Data Processing System, a military scientific computer introduced in 1952.
[121] The 28VS200BL transformer-rectifier weighed less than 16 pounds and had dimensions of 5" x 7" x 11" for the dc power conversion equipment needed for the North American A3J Vigilante military aircraft.
[134] In a Tung-Sol price guide of 1959, there was a 6394A as a non-military specification brand X with a description, "6336A with 26 volt heater" manufactured at the Livingston plant for $22.70.
Filament Vf 1.15 Volts / If: 4.5 Ampere / Description "Door-knob" type shape UHF transmitting triode, usable as oscillator, amplifier or mixer up to 1500 MHz.
: Chatham Electronics, Model SC-102, incorporated a thallium-activated sodium iodide crystal for changing radiation into scintillations of viewable light.
Designed specially with circuits that discriminate against spurious noise signals and count the scintillations, radiation is measured by minute variations in levels to be detected with output pointer needle readings on the instrument.
