Abstract

434,561. Discharge devices. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London.-(Patent - Treuhand - Ges. fur Elektrische Gl³hlampen; 11, Ehrenbergstrasse, Berlin) Aug. 8, 1934, No. 22951. [Class 39 (i)] In a vapour-filled discharge tube one or more heating resistances are arranged inside a channel which is formed, in part at least, of the material of the envelope and extends the whole, or the greater part, of the length of the envelope. A luminous discharge tube, provided with a filling of rare gases and mercury or sodium, has its envelope formed with a channel 9 which houses resistances 10, 11 connected to terminals 15 and-the electrodes 7. The tube is supported through caps 18 of porcelain or the material known under the Registered Trade Mark "Bakelite." In another form, the channel is formed by a depression which extends the length of envelope and is closed by insulating material. Specifications 309,608 and 321,915, [both in Class 39 (i)], are referred to.
