Abstract
804,911. Photo-:ric devices. CATHODEON Ltd. March 14, 1955 [March 15, 1954], No. 7443/54. Class 37. The photo-conductive layer on the target of a photo-conductive pick-up tube comprises a solid organic compound which is stable in vacuum, has a vapour pressure of less than 10<SP>-5</SP> mm. at normal tube operating temperatures, and is sufficiently opaque or coloured to absorb light in some part of the visible spectrum and/or the near ultra-violet or infra-red. Suitable compounds quoted are picene, chrysene and coronene, a copper phthalocyanine compound or a chlorinated derivative thereof, pinacryptol yellow, or the pigment sold as " Monolite Blue " (" Monolite " is a Registered Trade Mark). Combinations of layers or a layer of more than one compound may be used. Specifications 713,858 and 749,058, [Group XL (a)], are referred to.
