Abstract
511,879. Sealing lead-in conductors. VEREINIGTE GLUHLAMPEN UND ELEKTRIZITATS AKT.-GES. April 11, 1938, No. 11045. Convention date, April 9, 1937. [Class 36] A molybdenum or other refractory metal lead-in conductor in the form of a strip having a thickness exceeding 20Á, and preferably amounting to not less than 30Á, is sealed into quartz glass or other hard glass by heating the quartz or glass to its softening temperature and then mechanically pinching it on the strip, e.g. by tongs. When sealing a strip into a vessel having a quartz or other hard glass wall the interior of the vessel is preferably maintained during the sealing operation at a pressure lower than the pressure existing outside the vessel. Specification 474,867 is referred to.
