Abstract
501,624. Luminescent screens. GENERAL ELECTRIC CO., Ltd., JENKINS, H. G., and McKEAG, A. H. Nov. 26, 1937, No. 32694, [Class 39 (i)] Before application to the screen surface, luminescent material is mixed intimately with a small amount, e.g. ¢-1 per cent, of phosphoric acid and enough liquid to form a paste and after drying and grinding, the resulting powder is treated to eliminate the coarser particles. The liquid may be water, e.g. by employing a 5 per cent solution of the phosphoric acid of the kind sold under the Registered Trade Mark " Analar." The drying is conducted for one hour at 200‹ C. and the sieve is of 240 mesh. Phosphoric acid may also be used as the binder.
