Abstract
119,589. British Thomson - Houston Co., (General Electric Co.). Jan. 4, 1918. Perforating.-Glass whilst in a plastic condition is perforated by pressing through it one or more pins made of a metal which is not wetted by the glass, such as tungsten or molybdenum. In the arrangement shown, a series of pins are placed in apertures in a refractory block 3, and a bead of glass 7 carried by a stem 8 is pressed on to the bent upper ends of the pins in a mould 5 sup ported on a refractory plate 6 heated by a burner 9. Fig. 6 shows the device thus formed used for forming perforations in a side 11. If the perforation is effected when the glass is at the right temperature, coned perforations are produced as shown in Fig. 8.
