Filed:

Jul 14, 2000

Appl. No.:

09/616856

Inventors:

John M. Barnett - Covina CA

Assignee:

Vacco Industries, Inc. - South El Monte CA

International Classification:

B01D 2500

US Classification:

210446, 210488, 210498

Abstract:

The present invention relates to etched disc stack filters and particularly to such filters in which the etched discs include multiple arms in which are etched flow channels for the passage of a medium to be filtered and the removal or separation of a contaminant. In a particular embodiment of the invention, the etched discs may have an overall shape that is circular and may have filtering arms which radially extend from the center of each disc to the exterior border of the disc. The filtering arms may separate inlet and outlet openings. End caps may be attached at the ends of the disc stack and these end caps may have openings corresponding to the inlet and outlet openings in the discs in the disc stack.

International Classification:

B64D 1/12

US Classification:

2441373

Abstract:

A system including an extraction force transfer coupling link assembly is provided that extracts a cargo from an airborne aircraft with an extraction parachute and then deploys the cargo with a descent parachute. During a normal extraction the link assembly transfers a force from an extraction line to a deployment lanyard that deploys a descent parachute. In the event of a failed extraction, the assembly severs the deployment lanyard and jettisons the extraction parachute. The extraction force transfer coupling link assembly includes an ultra high molecular weight polyethylene rope that has one end of the deployment lanyard braided with the extraction line. The rope acts as both the extraction line for the cargo and the deployment lanyard for the descent parachute. By virtue of the ability to use a single rope, the link assembly is of simple construction and employs pyrotechnic cutters to effect the release of the extraction line and deployment lanyard rather than conventional mechanical interlocks.

Abstract:

An anode for an electron beam laser is formed by a thin metallic foil which functions both as a laser cavity wall having an airtight seal, and as a window which permits the passage of electrons therethrough into the laser cavity. This foil anode is supported on a frame structure in a manner such that the foil presents a smooth surface for the laser gas flow and the frame structure provides cooling for the anode to dissipate the heat generated by the electron flow. This frame structure includes a plurality of similar side-by-side, longitudinal, substantially flat, web elements which are separated from each other by gaps through which the electrons can pass. The web elements have cooling tubes welded to each of the opposite edges thereof, one of the tubes being capped with a flat strip which provides a flat surface against which the foil anode can be supported. The web elements are supported at their opposite ends by support blocks which are used to mount these elements in position between the electron gun and the laser cavity, with manifolds being provided in each of the support blocks for feeding cooling fluid to the tubes. The web elements are structurally supported and separated from each other by comb members which extend thereacross between the end blocks.
