Abstract

829,025. Cathode-ray tubes. SYLVANIATHORN COLOUR TELEVISION LABORATORIES Ltd. Nov. 12, 1957 [Dec. 10, 1956], No. 37686 /56. Class 39(1). The electron gun of a cathode-ray tube has a cathode C, Fig. 3, and an apertured grid G, Fig. 4, only one of whose apertures is aligned with the aperture in the first anode A, so that the beam current is smaller than the current to the first anode. Specification 822,552 is referred to.
