Abstract

1,105,893. Signalling by visible signals. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. 21 Dec., 1966 [10 Jan., 1966], No. 1020/66. Heading G4F. An intermittent electric current supply circuit includes a controllable rectifier device 3 in series with a current source 1 and a flasher bulb 6 which is so designed that it intermittently interrupts the current and causes the 'device 3 to be in a non-conductive condition. A photo-cell 5 is provided to apply a triggering signal to device 3 when the resistance of photocell 5 is increased by darkness. The circuit may be arranged on a printed circuit card enclosed in a marker buoy. An attitude sensing mercury switch 2 is included in the circuit to interrupt the current supply or to interrupt the supply of triggering signals to device 3 when the circuit is held in other than a predetermined attitude.
