| abstract | 341,716. Discharge apparatus. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London.-(Assignees of Patent-Treuhand-Ges. f³r Elektrische Gl³hlampen, 11, Ehrenbergstrasse, Berlin.) Jan. 20, 1930, No. 1980. Convention date, Feb. 11, 1929. [Class 39 (i).] A luminous electric discharge tube of the kind having a filling of a common gas such as carbon dioxide, or a mixture of a common gas and a rare gas, is provided with a gas replenishing means comprising a porous container 9, Fig. 1, within which is a powdered, gas-emitting, decomposable substance enclosing a heating-coil 11. The porous container may be made of carbon or a sintered oxide, or of thin aluminium, and the powdered gas-emitting substance contained therein may consist of magnesium carbonate, sodium azide, or lithium hydride, according to the gas used for filling the tube. The heating-coil 11 may be connected to the secondary 18 of a small transformer connected in one of the supply leads 4 of the discharge tube, or it may be connected to the middle turns of the secondary winding 6 of the supply transformer. The electrodes may be cupshaped, and in a modification, Fig. 4, the porous container 9 is mounted within a hollow sheet electrode 3 and connected to the same supply lead 5. Specification 313,292, [Class 39 (i), Electric lamps, Arc &c.], is referred to. |
