Abstract

822,558. Cathode ray tubes. GENERAL ELECTRIC CO. March 16, 1956 [March 16, 1955], No. 8326/56. Drawings to Specification. Class 39(1). The scale or grid of a cathode ray oscilloscope is deposited directly, preferably by photoetching, on the internal surface of the transparent tube end and the luminescent screen is deposited on top of the grid. The grid may also be luminescent and provided with means for exciting it without exciting the main screen. Specification 695,335 is referred to.
