Abstract
5 9 9 , 2 6 8 . Electrode materials and processing. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., BANKS, G. B., and FAGAN, C. P. May 2, 1945, No. 11154. Drawings to Specification. [Class 39 (i)] [Also in Group XXXVI] Re-radiation of heat from the anode to the cathode of a thermonic valve is prevented by coating the inside of the anode with a black layer, comprising nickel which has been electrodeposited in a state of fine division. An example is described, [see Group XXXVI].
