Microwave Treatment Of Vulcanized Rubber

US Patent:
6420457, Jul 16, 2002
Filed:
Apr 4, 2000
Appl. No.:
09/542201
Inventors:
George G. Wicks - Aiken SC
Rebecca L. Schulz - Aiken SC
David E. Clark - Gainesville FL
Diane C. Folz - Gainesville FL
Assignee:
Westinghouse Savannah River Company, LLC - Aiken SC
International Classification:
C02K 304
US Classification:
523300, 521 41, 524492, 524495
Abstract:
A process and resulting product is provided in which a vulcanized solid particulate, such as vulcanized crumb rubber, has select chemical bonds broken by microwave radiation. The direct application of microwaves in combination with uniform heating of the crumb rubber renders the treated crumb rubber more suitable for use in new rubber formulations. As a result, larger particle sizes and/or loading levels of the treated crumb rubber can be used in new rubber mixtures to produce recycled composite products with good properties.

Method For Recovering Metals From Waste

US Patent:
5843287, Dec 1, 1998
Filed:
Jan 19, 1996
Appl. No.:
8/605293
Inventors:
George G. Wicks - North Augusta SC
David E. Clark - Gainesville FL
Rebecca L. Schulz - Gainesville FL
Assignee:
The United States of America as represented by the United States
Department of Energy - Washington DC
International Classification:
C07B 6300
US Classification:
20415715
Abstract:
A method for recovering metals from metals-containing wastes, and vitrifying the remainder of the wastes for disposal. Metals-containing wastes such as circuit boards, cathode ray tubes, vacuum tubes, transistors and so forth, are broken up and placed in a suitable container. The container is heated by microwaves to a first temperature in the range of approximately 300. degree. -800. degree. C. to combust organic materials in the waste, then heated further to a second temperature in the range of approximately 1,000. degree. -1,550. degree. C. at which temperature glass formers present in the waste will cause it to melt and vitrify. Low-melting-point metals such as tin and aluminum can be recovered after organics combustion is substantially complete. Metals with higher melting points, such as gold, silver and copper, can be recovered from the solidified product or separated from the waste at their respective melting points. Network former-containing materials can be added at the start of the process to assist vitrification.

Bipolar Electrosurgical Knife

US Patent:
4202337, May 13, 1980
Filed:
Jun 14, 1977
Appl. No.:
5/806529
Inventors:
John J. Hren - Gainesville FL
David E. Clark - Gainesville FL
David A. Jenkins - Gainesville FL
Paul F. Johnson - Gainesville FL
Assignee:
Concept, Inc. - Clearwater FL
International Classification:
A61B 1736, A61N 302
US Classification:
12830314
Abstract:
An electrosurgical instrument for cutting, spot coagulation and point coagulation comprising a nonconductive handle which holds a blade assembly comprising a plurality of electrodes and an insulation member separating the electrodes. The blade assembly comprises an active center electrode of specified thickness with a recessed tip and is mounted to an extruded insulation member so that it extends outwardly from the insulation member to form a cutting edge. Split side return electrodes are symmetrically mounted to the insulation member and separated from the center electrode by the insulation member. The electrode area ratio of the return electrode area to the active electrode area falls between 0. 70 and 2. 0 allowing consistent bipolar operation. The electrodes are connected inside the nonconductive handle to a circuit whose output consists of a high frequency electrical current which forms a circuit through tissue intervening between and in contact with the electrodes when the instrument is used.

Inorganic Salts As Peptizing Agents In The Preparation Of Metal Oxide Sol-Gel Compositions

US Patent:
4801399, Jan 31, 1989
Filed:
Feb 25, 1986
Appl. No.:
6/841087
Inventors:
David E. Clark - Gainesville FL
William J. Dalzell - Gainesville FL
Brenda L. Adams - Gainesville FL
Assignee:
University of Florida - Gainesville FL
International Classification:
B01J 1300
US Classification:
25231501
Abstract:
A novel method for preparing sols from metal oxide precursors by using inorganic salts as the peptizing agent is disclosed herein. Sol-gels prepared from the sols are also disclosed. Ceramic coatings, monoliths, bodies and are formed. These structures have a particle size of down to 0. 0001 micron and are endowed with excellent packing characteristics as well as smoothness.

Deposition Of Ceramic Coatings Using Sol-Gel Processing With Application Of A Thermal Gradient

US Patent:
4921731, May 1, 1990
Filed:
Apr 28, 1987
Appl. No.:
7/045786
Inventors:
David E. Clark - Gainesville FL
William J. Dalzell - Gainesville FL
Brenda L. Adams - Gainesville FL
Assignee:
University of Florida - Gainesville FL
International Classification:
B05D 302
US Classification:
427314
Abstract:
A method of ceramic coating a substrate by thermodeposition from a sol made by hydrolyzing and peptizing organometallic compounds in water. The sol contains colloidal particles having a size between about 0. 0005 micron and about 10 microns and the deposited coatings have good packing characteristics as well as smoothness. Composite coatings are also deposited which contain reinforcing materials such as SiC embedded in the coated matrix. These coatings afford the substrate onto which they are coated excellent wear, anti-corrosion and insulating characteristics.
