Abstract

698,675. Electrode materials and processing. M-0 VALVE CO., Ltd., and WRIGHT, D. A. May 2, 1951 [May 3, 1950], No. 10944/50. Class 39(i) In a thermionic valve, the anode which forms part of, or is sealed through, the envelope is coated on that part which is likely to be bombarded by electrons with gold. A copper anode may have an intermediate layer of nickel or rhodium or the copper may alloy with the gold during processing. Specification 646,015 is referred to.
