Abstract

536,751. Discharge lamp envelopes. GENERAL ELECTRIC CO., Ltd., and KETTLEWELL, E. March 20, 1940, No. 5211. [Class 39 (i)] [Also in Group XXXVII] In a H.P.M.V. electric discharge device with a quartz envelope the junction between the main envelope part 1 and the piece 4 carrying at least one lead 5 is made between extensions 3, 7 much thinner than the envelope wall, so that they can be fused by external heating only. The joint is thickened by applying additional quartz 8. Specification 518,331 is referred to.
