Title: Pressure die moulding of hollow glass shapes with close dimension - interiors
IPC: C03C27/02
Filed: 1971-02-02
Abstract: The glass housings with sharp edged melted in metal components are produced by the placing of a lump of glass into a split die with a core insert projecting into the die cavity into which also project the metal inserts.

On heating in a reducing atmos. the glass softens and flows filling up the die cavity and surrounding the metal inserts, following which the assembly is cooled slowly. In the prefd. technique the glass lump inserted into the die has a slightly smaller dia. than the die bore. The method is used in the mfr. of electronic valves yielding repetitively accurate shaped components.

Patent DE-2153063-A1 (DE)
Title: Preventing crystallisation of quartz glass - by thermal treatment with metal oxide or salt
IPC: C03C17/23
Filed: 1971-10-25
Abstract: Cristobalite crystallisation of quartz glass is hindered by applying onto the glass article the oxide of a gp. III metal or a salt yielding the same upon heating (pref.
