Abstract
586,616. Cathode - ray tubes. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and FAGAN, C. P. Oct. 27, 1944, No. 21009. [Class 39 (i)] The production of a mosaic electrode for a television camera tube involves the initial step of printing the mosaic pattern on one side of an insulating sheet 'by means of an etched metal plate, using a silver oxide ink. A coating of colloidal graphite or liquid bright silver on the other side of the insulating sheet forms the signal plate. A silver oxide ink is made by adding 40 grams of the oxide to 100 c.c. of a 1 per cent solution of pyroxylin in amyl acetate and ball-milling the whole to a smooth consistency. The oxide on the printed mosaic is reduced to silver by heating.
