Sometimes however, especially in the manufacture of ceramic vacuum vessels having leads sealing melts, so-called the leads is impaired even if no getter material has been deposited between them.
will be understood from the folescription, reference being had to the n which:
drawn to 1 and 2, is a fragmenaterial from which the ular hoods leads, as shown in 1. Such hoods are ads, that is to say, of vessel I while the Alternatively, coating 6 metal, preferably a precious metal.
The arrangement represented in Figs. 2 and 3 has a lead 8 composed of two conductors b, 0. Conductor b, fast seal 1, is of another material having a vapreferably extends beyond the weld d.
The arrangement shown in Figs. 2 and 3 thus makes use of the fact that materials having a vaporizable oxide surface, as is the case with on lead 8, before this is sealed i nto the base 4. The invention is applicable,
for instance, to
What is claimed is:
1. A leading-in wire structure for a vacuum vessel comprising a member of insulating material having leading-in conductors passing therethrough each of said conductors being composed of a first part having a vaporizable oxide surface and a second part free from such surface, serial- 1y connected, said first part being fixed to said member by a vacuum tight seal at a point intermediate its ends, and a protective means free from vaporizable oxide surface extending from said seal to a point intermediate the ends of said second part.
2. A device according to claim 1, wherein the two parts are united with each other end to end.
EDMUND LoPP.
