Abstract

275,152. Westinghouse Brake & Saxby Signal Co., Ltd., (Assignees of Ackerly, D. G.). July 29, 1926, [Convention date]. Coating. - In manufacturing a rectifying element, a copper blank is oxidized to produce cuprous oxide.. and is then heated in an atmosphere containing little or no oxygen to improve the crystal structure of the oxide layer. Both steps may be accomplished in the same furnace, a temperature in the neighbourhood of 1,000' C. being maintained. Specification 257,305 is referred to.
