Method Of Preparation Of Dispersion Strengthened Silver Electrical Contacts

US Patent:
4018630, Apr 19, 1977
Filed:
Sep 5, 1975
Appl. No.:
5/610525
Inventors:
James S. Hill - Cranford NJ
Emil L. Carbone - Paramus NJ
Victor G. Mooradian - Summit NJ
Walter G. Keyes - Spotswood NJ
Assignee:
Engelhard Minerals & Chemicals Corporation - Murray Hill NJ
International Classification:
H01B 102, C22C 105, C22C 510
US Classification:
148 115P
Abstract:
Preparation of compositions of silver and CeO. sub. 2 by powder metallurgy techniques overcomes problems inherent in melting silver and pure cerium and subsequently internally oxidizing the cerium in the mixture. Small concentrations of CeO. sub. 2 substantially improve the electrical contact properties of silver. Silver with dispersed CeO. sub. 2 is superior to silver alone for use as an electrical contact because of much greater resistance to arc erosion and welding and only slightly higher contact resistance.

Thick Film Thermocouples

US Patent:
4110124, Aug 29, 1978
Filed:
Sep 22, 1975
Appl. No.:
5/615583
Inventors:
Allen R. Robertson - Edison NJ
James S. Hill - Cranford NJ
Assignee:
Engelhard Minerals & Chemicals Corporation - Iselin NJ
International Classification:
H01V 114, H01B 102
US Classification:
136236R
Abstract:
A thick film thermocouple matching the performance of solid wire thermocouples and capable of operating at high temperatures with minimal drift is produced by (1) forming two powdered metal pastes of differing compositions, each including a frit which is substantially neutral with respect to the metal components of the respective paste and has essentially no effect upon the thermoelectric EMF, (2) applying the pastes to a surface to form a pair of thick film elements overlapping at one point which form a thermocouple upon firing, (3) firing the applied pastes, and (4) attaching leads to the fired elements and assembling the finished thermocouple. Optionally, the thermocouple elements or legs may be overglazed to protect them against damage to the metal films and to improve stability during continuous use at high temperatures.

Electrical Contacts Of Dispersion Strengthened Gold

US Patent:
4018599, Apr 19, 1977
Filed:
Sep 5, 1975
Appl. No.:
5/610526
Inventors:
James S. Hill - Cranford NJ
Emil L. Carbone - Paramus NJ
Victor G. Mooradian - Summit NJ
Walter G. Keyes - Spotswood NJ
Assignee:
Engelhard Minerals & Chemicals Corporation - Murray Hill NJ
International Classification:
C22C 502
US Classification:
75165
Abstract:
Small concentrations of certain dispersed oxides such as CeO. sub. 2 substantially improve the electrical contact properties of gold. Gold with dispersed CeO. sub. 2 is superior to gold for use as an electrical contact because of much greater resistance to arc erosion and welding and only slightly higher contact resistance.
