Abstract

1309493 Cathode ray tubes RCA CORPORATION 30 April 1971 [30 April 1970] 12403/71 Heading H1D An electron discharge tube such as a colour television display tube is unsealed for repair or for salvage of usable parts by perforating a metallic portion of the envelope and the envelope wall is separated at a position spaced from this portion, for example at a glass neck portion. The metallic portion may be a high voltage connection terminal and is pierced with a pointed tool driven manually or mechanically, and if the terminal is of ductile material no chips or the like are introduced into the tube; after piercing, the tool may be left in place to allow gas to pass slowly into the tube, or it may be removed. Before re-evacuation the opening may be sealed with a frit material or with a pin which is sealed by a frit material or by welding.
