Abstract

526,612. Gas - filled electric incandescent lamps. BRITISH THOMSON-HOUSTON CO., Ltd., SCOTT, W. J., DAVIES, L. J., and COWHIG, W. T. March 22, 1939, No. 9070. Drawings to Specification. [Class 39 (ii)] [Also in Group XL] The envelope of an incandescent lamp or electric discharge lamp or valve is filled with a gas at super atmospheric pressure by (i) exhausting the envelope (ii) filling a compression pump with the gas etc. to be used in the envelope (iii) delivering the gas by the pump to the envelope and (iv) sealing off the envelope. A single three-way valve controls the piping to the envelope and pump. A liquid piston pump may be used.
