Abstract

441,113. Discharge lamps. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London.-(Assignees of Giard, E. A. ; 12th Street, Milwaukee, Wisconsin, U.S.A.) April 5, 1934, No. 10337. Void [Abridged as open to inspection under Sect, 91 of the Acts, Oct. 22, 1934]. [Class 39 (i)] Ignition is facilitated by means of auxiliary elec, trodes 6 which are connected together by a resistance 8 or by means of one auxiliary electrode which is connected to the main electrode more remote therefrom through a resistance. A variable impedance 13 is connected in series with the primary of the supply transformer.
