Abstract

463,642. Luminescent screens. FERRANTI, Ltd., and TAYLOR, M. K. Oct. 3, 1935, No. 27285. [Class 98 (i)] [Also in Group XV] Fluorescent or phosphorescent material is caused to adhere to' a vitreous surface of sodaglass, such as a sheet or the wall of a cathoderay tube, by spreading the material thereon after treating the surface with caustic soda, e.g. in 5-10 per cent solution. The product may then be baked. Parts of the surface which are not to be coated may be protected with a removable resist such as wax. Specification 453,507 is referred to.
