Abstract

445,344. Glass manufacture. JEROME & BONNEFOY & CIE, 37, Rue Raspail, Courbevoie, Seine, France, and LAMPE YVEL, AUTO LAMPE & CIE, ANCIENS ETABLISSEMENTS L. LEVY ET A. MONNIER, 12, Rue Torricelli, Paris. Sept. 7, 1934, No. 25817. Convention date, Oct. 27, 1933. [Class 56] The bulb of an incandescent electric lamp, particularly for motor-car headlamps, consists of a glass which is made by melting a batch containing cadmium sulphide and sulphur together with selenium and tin oxide. Preferably, the selenium and tin oxide are added to the batch in the proportion of 0À005 parts by weight and 0À04 parts, respectively, to 10 parts of sand.
