Abstract
467,362. Glass manufacture. GENERAL ELECTRIC CO., Ltd. (Patent-Treuhand-Ges. f³r Elektrische Gl³hlampen) April 6, 1936, No. 10095. [Class 56] A refractory glass, which is free from boric acid, and alkalies, contains 80-98 per cent of silica, 2-12 per cent of alumina, and 0-8 per cent of an alkaline earth, and its softening temperature is not below 1000‹ C. The glass is intended particularly for forming the envelopes of high-pressure metal vapour electric discharge lamps. Specifications 18053/11 and 2176/13, [both in Class 56], and 463,889, are referred to.
