1,135,428. Metal to glass seals. WESTERN ELECTRIC CO. Inc. 21 April, 1966 [21 April, 1965], No. 17469/66. Heading C1M. [Also in Division B3] In applying radiant energy through a heatsensitive material to perform a manufacturing operation, the material being damaged by heat at a temperature below that necessary for the operation, the energy is passed through a heat sink which is transparent to the radiant energy and is in contact with the heat-sensitive material. The manufacturing operation may be the formation of a metal-to-glass seal in close proximity to a heat-sensitive material. Suitable materials for the heat sink are given. |
