Abstract
517,483. Cathode-ray tubes. BAIRD TELEVISION, Ltd., and JONES, V. A. July 29, 1938, No. 22623. [Class 39(i)] A television receiving device comprises a fluorescent screen flooded with ultraviolet light, the temperature of this screen being varied from point to point in accordance with the picture to be received ; in the arrangements described the variations of temperature is produced by electron impact The figure shows an apparatus with a fluorescent screen 2 illuminated from an ultra-violet source 4. On a photo electric cathode 5 is focused a negative image produced on the screen of a cathode ray tube 6, the electron image thus produced is focused on the screen 2.
