Abstract
527,854. Luminescent materials. GENERAL ELECTRIC CO., Ltd. (Patent-Treuhand-Ges. fur Elektrische Gluhlampen). April 21, 1939, No. 12047. [Class 39 (i)] Luminescent cadmium borate is mixed with luminescent magnesium and/or zinc tungstate and used in a low pressure mercury vapour lamp ; 50-65 per cent. of the first to 30-35 per cent. of the second material are proportions used.
