Abstract

454,071. Fusing and working silica. HERAEUS GES., W. C., Hanau-on-Main, Germany. Feb. 18, 1936, No. 4930. Convention date, Feb. 18, 1935. [Class 56] In the manufacture of fused quartz tubes provided with side tubes, flanges, &c., the latter are secured in a centrifugal mould a packed with sand and the main tube is then formed by drawing an are l along the tube, the inner portions of the side tubes &c. being fused at the same time so as to be firmly welded to the main tube. Specification 330,943, [Class 56], is referred to.
