Abstract

465,060. Cathode-ray tubes. MILLER, H. Oct. 29, 1935, No. 29892. Drawings to Specification. [Class 39 (i)] A television-transmitting tube comprises a screen composed of a conductive signal plate covered with a photo-conductive material, which material is coated with a substance which is a better secondary-electron emitter than the material itself. The photo-conductive material may be a sulphide or oxide of lead, thallium, mercury, cadmium, silver, zinc, copper, or antimony, or a halogen compound of lead, thallium, mercury, cadmium, or silver, or a crystalline form of selenium, sulphur, phosphorus, or iodine. The coating-material may be the borate of an alkali metal such as lithium, applied by spraying. on the screen a 3 per cent aqueous solution, or metallic caesium, distilled on to the screen. The thickness of the coating should be of the order of 10<-6> cm. The invention is applicable to tubes of the kind described in Specification 463,297.
