Segmented Lasing Tube For High Temperature Laser Assembly

US Patent:
5497392, Mar 5, 1996
Filed:
Jan 26, 1995
Appl. No.:
8/381479
Inventors:
Richard H. Sawicki - Danville CA
Terry W. Alger - Tracy CA
Raymond G. Finucane - Pleasanton CA
Jerome P. Hall - Livermore CA
Assignee:
The United States of America as represented by the United States
Department of Energy - Washington DC
International Classification:
H01S 303
US Classification:
372 62
Abstract:
A high temperature laser assembly capable of withstanding operating temperatures in excess of 1500. degree. C. is described comprising a segmented cylindrical ceramic lasing tube having a plurality of cylindrical ceramic lasing tube segments of the same inner and outer diameters non-rigidly joined together in axial alignment; insulation of uniform thickness surround the walls of the ceramic lasing tube; a ceramic casing, preferably of quartz, surrounding the insulation; and a fluid cooled metal jacket surrounds the ceramic casing. In a preferred embodiment, the inner surface of each of the ceramic lasing tube segments are provided with a pair of oppositely spaced grooves in the wall thereof parallel to the center axis of the segmented cylindrical ceramic lasing tube, and both of the grooves and the center axis of the segmented cylindrical ceramic lasing tube lie in a common plane, with the grooves in each ceramic lasing tube segment in circumferential alignment with the grooves in the adjoining ceramic lasing tube segments; and one or more ceramic plates, all lying in a common plane to one another and with the central axis of the segmented ceramic lasing tube, are received in the grooves to provide additional wall area in the segmented ceramic lasing tube for collision and return to ground state of metastable metal atoms within the segmented ceramic lasing tube.

Ice Barrier Construction

US Patent:
4523879, Jun 18, 1985
Filed:
Apr 16, 1982
Appl. No.:
6/369042
Inventors:
Raymond G. Finucane - Houston TX
Hans O. Jahns - Houston TX
Assignee:
Exxon Production Research Co. - Houston TX
International Classification:
E02D 2100
E02B 1700
US Classification:
405217
Abstract:
A method is provided for constructing spray ice barriers to protect offshore structures in a frigid body of water from mobile ice, waves and currents. Water is withdrawn from the body of water and is sprayed through ambient air which is below the freezing temperature of the water so that a substantial amount of the water freezes as it passes through the air. The sprayed water is directed to build up a mass of ice having a size and shape adapted to protect the offshore structure. Spray ice barriers can also be constructed for the containment of pollutant spills.
