Title: Improvements in gas-tight seals wherein electric conductors pass through quartz and like vitreous material
IPC: H01J5/32
Filed: 1938-03-23
Abstract: 512,257. Sealing lead-in conductors into vitreous material. GENERAL ELECTRIC CO., Ltd., and SCHNETZLER, K. G. March 23, 1938, No. 8903. [Class 36] In a strip seal for passing current through the wall of a quartz or like vitreous vessel, of the type wherein a thin molybdenum or other metal strip having relatively stout conductors projecting from each end is embedded in vitreous material by collapsing a tube of the material on the strip, the current-carrying capacity of the strip is increased by so attaching the stout conductors to the strip that current passes from one conductor to another through the strip in a direction approximately perpendicular to the axis of the tube that is collapsed on it. Fig. 1 shows a seal wherein conductors 2, 3 are attached along opposite edges of opposite sides of a strip 1 which is embedded in a collapsed quartz tube 4. In a modified construction, Fig. 2, the conductor 2 is forked and the two limbs of the fork are attached to opposite edges of the same side of the strip ; the conductor 3 is welded along the middle of the opposite side. As shown in Fig. 5 the strip is bent into cylindrical form and sealed between a vitreous core 5 and a vitreous tube 4 which is collapsed on the core and strip. A plurality of parallel-connected conductors 2 entering the strip from one end and attached to it along a considerable part of its length are intercalated with a plurality of similar conductors 3 entering from the other end of the strip. In all constructions each conductor may be in the form of a strip whose width is parallel to the surface of the strip 1. When the conductors and the strip are of molybdenum the conductors may be nickel-plated to prevent the vitreous material sticking thereto and to ensure good electrical union between the strip and conductors when they are welded together. Specification 489,630 is referred to. The Provisional Specification describes also a construction wherein conductors 2, 3, Fig. 3, are arranged on opposite sides of a strip 1 with their ends overlapping one another, the overlapping portions being welded to the strip.
