Abstract

367,351. Discharge lamps. LEDERER, A., Hermesvilla, Vienna. Nov. 15, 1930, No. 34454. Convention date, Dec. 4, 1929. Addition to 364,088. [Class 39 (i).] The glow discharge lamps described in the parent Specification for use on alternating current are modified by arranging the electrodes sufficiently close together that their respective aureoles combine to form a single apparent aureole.
