Abstract

474,797. Cathode-ray tubes. ZEITLINE, V., ZEITLINE, A., and KLIATCHKO, V. Dec. 5, 1936, No. 33436. Convention date, June 26. [Class 39 (i)] In means for producing metallic coatings on the inner surface of cathode-ray tubes and making contact therewith comprising a spring arm C carrying metal to be volatilized to form the coating and held in position parallel to the axis of the tube by a wire F which is afterwards fused to allow the arm to make contact with the coating, the fusible wire F is secured to one of the deflector plates and the metal G to be volatilized in the neighbourhood of this plate, so that the metallic coating is thickest in the portion of the tube opposite the deflector plates.
