Abstract

457,244. Fluorescent screens. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. Feb. 25, 1936, No. 5671. Convention date, May 28, 1935. [Class 98 (i)] The fluorescent material is applied to the support from a suspension of the material mixed with a highly-nitrated binding agent, and the binding agent is removed by burning, as by heating to 300‹ C. in air or oxygen. In examples, (1) calcium tungstate is applied from a suspension in amyl acetate containing nitrocellulose as binder, and (2) zinc silicate is applied from a suspension in alcohol containing collodion as binder. Cadmium tungstate, zinc sulphide and mixtures of zinc sulphide and cadmium sulphide may be used.
