Abstract

478,733. Fluorescent screens. GERMER, E. April 9, 1936, No. 13859 /37. Void. Convention date, April 11, 1935. Divided out of 468,531. Drawings to Specification. [Class 98 (i)] In forming a thin layer of luminescent material on the surface of a vitreous support, a gas pressure considerably exceeding atmospheric is applied at a temperature at which the support is soft. The subject-matter is the same as that described in Specification 468,531. Specification 421,955 also is referred to.
