Abstract

465,135. Glass manufacture. WARREN, T. W. Nov. 1, 1935, No. 30247. [Class 56] [Also in Groups XL and XVIII] To form a glass container for an electric discharge lamp, a glass sheet 2 with parallel ridges 20 and grooves 21 below the ridges is fused to a glass cover plate 1 to form discharge channels 3 between the ridges. The moulded sheets 1, 2 are fused together by gas jets applied on opposite sides, one in a groove 21 and one above the sheet 1, to fuse the tops of the ridges 20 to the sheet 1.
