Filed:

Jul 22, 2005

Appl. No.:

11/186941

Inventors:

Derek J. Angier - Simpsonville SC, US
James F. Rhodes - Greer SC, US
William M. Rogers - Taylors SC, US

Assignee:

Advanced Composite Materials Corp. - Greer SC

International Classification:

C01B 31/36

US Classification:

423345, 423346, 501 88, 501 951, 428221, 442362

Abstract:

Silicon carbide fibers are produced by mixing discontinuous isotropic carbon fibers with a silica source and exposing the mixture to a temperature of from about 1450 C. to about 1800 C. The silicon carbide fibers are essentially devoid of whiskers have excellent resistance to oxidation and excellent response to microwave energy, and can readily be formed into a ceramic medium employing conventional ceramic technology. The fibers also may be used for plastic and metal reinforcement.

Filed:

Oct 26, 1989

Appl. No.:

7/426540

Inventors:

James F. Rhodes - Greer SC
Chester J. Dziedzic - Greenville SC
Ronald L. Beatty - Greer SC

Assignee:

Advanced Composite Materials Corporation - Greer SC

International Classification:

B24D 334

US Classification:

51309

Abstract:

Cutting tools are disclosed which are comprised of composite bodies comprising a ceramic matrix reinforced by ceramic whiskers. The ceramic matrix may be alumina or silicon nitride, and may contain toughening components. The whiskers are preferably silicon carbide, but may be other known ceramic whiskers. Whisker content in the composite is 2-40%, with higher contents generally used for tools when the expected service involves interrupted cutting and lower contents generally used for continuous cutting tools.

Inventors:

William M. Rogers - Taylors SC
James F. Rhodes - Greer SC

Assignee:

Advanced Composite Materials Corporation - Greer SC

International Classification:

C04B 3332

US Classification:

264640

Abstract:

A composite and pressureless sintering process for making whisker-reinforced alumina composites using a nitride modifier. The whiskers are milled to an aspect ratio of less than 10. Green preform bodies are surrounded by a carbonaceous material during the sintering process to prevent direct exposure of the body surface to the atmosphere within the sintering furnace during the sintering step.

International Classification:

G06K 1500

US Classification:

235383

Abstract:

A system and method for tracking semiconductor wafers through processing operations performed at a plurality of stations. A reader reads information relating to and identifying the wafers from a tag mounted on a wafer carrier. The tag has a memory which includes a plurality of pages storing the information. A plurality of antennas are connected to the reader. The antennas each have a transmission range which defines a reader position and the reader and tag communicate by radio frequency signals via one of the antennas when the carrier is at the respective reader position. A host computer and reader communicate in accordance with an interface protocol by which the host computer commands the reader to read the stored information from one or more selected tag pages and the reader provides the stored information read from the selected tag pages to the host computer.

US Classification:

501 87

Abstract:

A composite and pressureless sintering process for making whisker-reinforced alumina composites using about 2 to about 7. 5 wt. % of a nitride modifier consisting essentially of silicon nitride, aluminum nitride, or mixtures thereof produces a sintered body having a density of greater than about 95% theoretical.
