Abstract

1299178 Lamps J HARTLEY and E J PILKINGTON 3 Feb 1970 [4 Feb 1969] 6034/69 Heading F4R [Also in Division G4] A portable warning device comprises electric lamps connected in parallel to a battery which is in series with a switch and a flasher device. The warning device may be worn by pedestrians or climbers to indicate their position. The lamp circuit may include a mercury switch which completes the circuit when tipped. In addition, an audible or short wave signalling device may operate when the switch is closed.
