Microwave Induced Plasma Process For Producing Tungsten Carbide
US Patent:
5131992, Jul 21, 1992
Filed:
May 20, 1991
Appl. No.:
7/704832
Inventors:
Ronald H. Church - Birmingham AL
Johanna B. Salsman - Tuscaloosa AL
Bobby J. Hamner - Northport AL
Johanna B. Salsman - Tuscaloosa AL
Bobby J. Hamner - Northport AL
Assignee:
The United States of America, as represented by the Secretary of the
Interior - Washington DC
Interior - Washington DC
International Classification:
H05H 146
B22F 914
B22F 914
US Classification:
204164
Abstract:
A method of heating reactant materials in a plasma chamber to achieve a reaction temperature by enveloping the materials in a microwave induced electric plasma. The plasma chamber positioned in the microwave waveguide is filled with a gas and predetermined quantities of the reactant materials are placed in the chamber or reactor. A microwave produced electric field is passed through the gas to ionize it and produce an electric plasma that envelopes the reactant materials. The process may be used in a variety of high temperature chemical processes such as the production of tungsten carbide.
Short Range Trapped Miner Locator
US Patent:
4491971, Jan 1, 1985
Filed:
Mar 8, 1983
Appl. No.:
6/473298
Inventors:
William E. Webb - Tuscaloosa AL
Ronald H. Church - Birmingham AL
Ronald H. Church - Birmingham AL
Assignee:
The United States of America as represented by the Secretary of the
Interior - Washington DC
Interior - Washington DC
International Classification:
H04B 1034
US Classification:
455100
Abstract:
A short range, low power, radio wave transmitter which acts as a miner locator. The transmitter is incorporated with the cap lamp circuitry for the miner. It utilizes the same self-contained power source and its wire connection thereto acts as the transmitter's antenna. No action on the miner's part is necessary in order to begin the transmission which may be on a specific identifying frequency for each miner. An electronic crowbar circuit may be used to conserve power for the transmitter by cutting off power to the cap lamp should the voltage across the self-contained power source fall below a preset level. This enables the transmitter to function for several days by reducing the load on the power source.
