Abstract

223,681. Pearce, G., and Watson & Sons (Electro-Medical), Ltd. Aug. 3, 1923. Actuating and controlling.-Direct current from a source f is rhythmically interrupted by a neon or like lamp a connected in known manner in series with a resistance d shunted by a condenser b. The invention consists in connecting a relay c of the electromagnetic or moving-coil type in the circuit, so as to control stronger currents in a second circuit e. The invention is applicable for operating a flash sign and for other purposes.
