Abstract

517,482. Cathode-ray tubes. BAIHD TELEVISION, Ltd., and JONES, V. A. July 29, 1938, No. 22622. [Class 39 (i)] The light sensitive mosaic 2 is scanned by a beam from a gun 3 and is also flooded with electrons from a secondary emitting electrode 4 which i itself scanned by a bean from a gun 5. The electrode may be a transparent coating on the envelope and i may be of mosaic form it may be made as a grid, the gun 5 being then on the side of the electrode 4 remote from the mosaic 2.
