US Patent:

43100066, Jan 12, 1982

Filed:

Jul 20, 1979

Appl. No.:

6/059315

Inventors:

Charles H. Hibbitts - Chester VA
Byron F. Price - Chester VA
Everett C. Cogbill - Richmond VA
James G. Kelly - Richmond VA
James E. Glass - Sutherland VA

Assignee:

American Brands, Inc. - New York NY

International Classification:

A24B 318

US Classification:

131290

Abstract:

The invention disclosed is a method and apparatus for expanding particles of cured tobacco by means of liquid and gaseous carbon dioxide which is sprayed into a mass of the tobacco in a closed pressure vessel. The thus treated tobacco is removed from the vessel and heated such that rapid release of the carbon dioxide effects expansion of the tobacco.

B23K 1005

US Classification:

2281245

Abstract:

The laser brazing of the present invention offers the unique advantage of producing a high temperature hermetic bond while limiting the heat affected zone to the region of the joint. Laser brazing joins infrared (IR) and radio frequency (RF) ceramic materials to metals for radome applications. Using AG--Cu--Ti brazing alloys, zinc sulfide (ZnS) infrared windows were laser brazed to cylindrical titanium housings with no thermal degradation observed in crystalline properties of ZnS. Innovative glass-ceramic materials were also used as braze filler to produce over 30 ceramic-to-metal couples, including titanium Zns, Pyroceram/Kovar and niobium/sapphire. Benefits are in the production of strong, high temperature, hermetically sealed joints in aircraft and high velocity missile systems. An optimized laser brazing system is provided.
