Abstract

533,636. Discharge apparatus. FODOR, J. July 17, 1939, No. 20783. [Class 39 (i)] In a glow discharge lamp having no internal electrodes gettering can be effected from time to time during the life of the lamp. This can be done by having spaced getter materials which can be separately heated or different getters responsive to differing temperatures.
