Abstract
636,932. Glass. SOC. ANON. DES MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE ST.-GOBAIN, CHAUNY, & CIREY. Dec. 8, 1947, No. 32382. Convention date, Dec. 7, 1946. [Class 56] Multi-cellulose glass is made from a glass having a coefficient of linear expansion not greater than 65 X 10<SP>-7</SP>. The cooling, after the swelling step, is carried out rapidly and, owing to its low expansion, the final contraction of the internal portion of the glass is insufficient to cause any damage or strain in the outer portion. Two examples of glasses are SiO 2 (i) 80.5 per cent, (ii) 59.0 per cent; B 2 O 3 12.5, 5.0; Na 2 O 4À5, 1.0 ; Al 2 O 3 2.5, 18.0; CaO nil, 7.0; MgO nil, 10.0. Powdered carbon is used as the gasefying agent:
