Abstract
489,965. Thermionic distributers. FERNSEH AKT.-GES. Feb. 8, 1937, No. 3686. Convention date, Feb. 7, 1936. [Classes 39 (i) and 40 (v)] A surface 6 emits radiation under the influence of an incident electronic beam, and the radiation is incident on a plurality of elements 8, the charge on which is varied by the incident radiation. The fluorescent screen 6 may be made of discrete areas corresponding to the photo-electric elements 8 or the fluorescent material scanned by the cathode-ray may be continuous. The light emitted is focused by a lens 7 on the photo-electric elements in a separate evacuated envelope 9. According to modifications : the photo-electrons are incident on secondary-emitting electrodes to increase the number of electrons collected on the respective anodes, which are connected to an equal number of elements disposed in a beam of light to control its intensity, Fig. 2 (not shown); the cathode-ray tube 1 is made of quartz, and the screen 6 emits ultra-violet light, which is incident on electrometer leaves in air.
