Title: Improvements in or relating to vacuum-tight seals between metals and ceramic materials
IPC: H01J5/42
Filed: 1936-04-30
Abstract: 473,155. Uniting metal to ceramic material by heat. GENERAL ELECTRIC CO., Ltd. (Patent-Treuhand-Ges. f³r Elektrische Gl³hlampen) April 30, 1936, No. 12354. [Class 36] In a multiple vacuum tight seal through which a number of electric conductors, insulated from each other, pass from the interior to the exterior of a sealed vessel, metallic sealing members such as 2, 14, 15, Fig. 6, integral with respective conductors 1, 1<1>, and 1<11>, or connected thereto by soldering, welding, or the like, contact closely with a ceramic body or bodies 11-13 only over a surface or surfaces on which the metallic sealing members exert pressure when they contract, part at least of the ceramic surface or surfaces being coated with a metallic layer 5 to which the respective sealing member 2, 14, or 15 is soldered, at least one of these sealing members being annular and surrounding at least one conductor other than that to which it is connected. The cap 2, which may be made of iron or a nickel-iron alloy, is soldered to a metal layer 5 around a boss 3 on the ceramic body 11, which is in the form of a circular block, the top of the cap being spaced from the top of the boss, so that the only reaction between the cap and boss, when the seal cools, is perpendicular to the coated surface of the boss, tending to force the cap against the boss and compress the solder. between them. The outer rim of the block 11 is coated with metal 5 and soldered to the interior of a metal ring 14 which is similarly soldered to the exterior of a flange on another ceramic block 12, the lead 11 being attached to the interior of the ring 14 and passing through the central hole of the block 12. A metal ring 15 soldered around the block 12 is also soldered to a flange on another ceramic block 13 which may form part of the main envelope into which the three leads 1, 1<1>, 1<1><1> are introduced. All the soldered seals at the metal coatings 5 may be made at the same time, but if made separately, solders of different melting points can be used. Instead of the cap 2 shown in Fig. 6, alternative forms of seal may be used for the inner conductor 1. Fig. 3 shows a metal cylinder 8 which is placed around a layer of metal 5 on a ceramic boss 3 and soldered 'thereto by melting soldering material, for example a silver ring, on the boss, so that it flows over the top of the boss and fills the space between the cylinder 8 and layer 5 without contacting closely with the top of the boss, which has not been coated with the metal layer 5. Fig. 4 shows a further modification wherein a rounded boss 9 has the approximately vertical portions of its sides coated with the sintered metal layer 5, so that when molten solder flows over the boss to form a complete cap, it contacts closely only with the vertical portions. Specifications 294,880, [Class 36], and 456,048, [Group XI], are referred to.
