Abstract

427,765. Cathode-ray tubes. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, and SCHLESINGER, K., 39, Friedrichstrasse, Friedrichshagen, both in Berlin. Sept. 29, 1933, No. 22182/34. Divided out of and addition to 426,138, under which a Specification was laid open to inspection under Sect. 91 of the Acts, April 3, 1934. Drawings to Specification. [Class 39 (i)] In the tube described in the parent Specification, the paths of the separate cathode rays between the cathodes and the preliminary anodes are surrounded by cylinders screening the rays from each other and from the high tension leads.
