US Patent:

46620923, May 5, 1987

Filed:

Aug 1, 1985

Appl. No.:

6/761554

Inventors:

Han K. Kim - Elmhurst NY

International Classification:

G09F 112

US Classification:

40155

Abstract:

A metallic picture frame construction including corner frame elements which connect rectilinear segments in an attractive manner in which the interconnecting screws are concealed from view. The corner elements surround the ends of the rectilinear segments, and they are maintained in engagement solely by compressive forces exerted by the screws making unnecessary the drilling of holes in the rectilinear members. The invention has application to wood rectilinear segments as well, using wood screws which penetrate the corner elements and the rectilinear segments.

Appl. No.:

5/697175

Inventors:

Han J. Kim - Chelmsford MA
F. Joseph Reid - Acton MA

Assignee:

GTE Laboratories Incorporated - Waltham MA

International Classification:

B22F 302

US Classification:

75233

Abstract:

This application describes the addition of an alkali metal, generally in the form of a salt thereof, to a mixture of silver and cadmium oxide, prior to the sintering step, to improve the as-sintered densities of the resultant alloy material.

Appl. No.:

5/722855

Inventors:

F. Joseph Reid - Acton MA
Han J. Kim - Chelmsford MA

Assignee:

GTE Laboratories Incorporated - Waltham MA

International Classification:

B22F 300

Appl. No.:

8/206817

Inventors:

Han Kim - Cincinnati OH
Aubrey Bryant - Liberty OH
Steven F. Reed - Oxford OH
Robert I. Whitney - Brookville IN

Assignee:

Square D Company - Palatine IL

International Classification:

H01R 460

US Classification:

439210

Abstract:

An end feed connector for connecting a plurality of feed lines to a pre-bussed rigid conduit which has feed line connectors that fit in slots in an insulating housing. Within the housing, the slots communicate with conductive sleeves that are disposed in the pattern of the pre-bussed rigid conduit with which the end feed connector is intended to mate. Bus bars within the housing connect the feed line connectors to the sleeves.

Appl. No.:

6/751516

Inventors:

Han K. Kim - Elmhurst NY

International Classification:

B25B 2308

US Classification:

81452

Abstract:

A plurality of devices are disclosed for supporting threaded screws in a plane normal to a surface into which the screws are threaded. Each embodiment includes means for supporting the shank of the screw at points intermediate the ends thereof rather than only at the head thereof. The means is resiliently expandable to permit passage of the head of the screw past the supporting means for disengagement of the device after the screw has obtained substantial threaded purchase with an engaged structure.

Assignee:

GTE Laboratories Incorporated - Waltham MA

International Classification:

B22F 326

US Classification:

75200

Abstract:

This application describes a method of preparing cadmium-containing refractory metal-silver alloys by using a liquid phase sintering technique featuring a cadmium vapor over-pressure. The resultant alloys are useful as electric contacts in high electric current applications.
