Abstract
694,849. Welding glass. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 28, 1952 [April 2, 1951], No. 7993/52. Class 56. A method of sealing two large glass objects together, e.g. the cone and window of a cathoderay tube, whereby the parts to be sealed are preheated, placed in a rotary machine wherein the edges to be sealed are gradually melted e.g. by gas flames, and then placed in a cooling oven is characterised in that, after the preheating operation the sealing edges are rapidly fused together in the sealing machine, the article then being placed in a strain release oven having a temperature of 20-60‹ C. above the upper strain release temperature of the glass used. The article is subsequently cooled in an oven in the usual manner.
