Abstract

157,215. Sarnmark, A. U. Dec. 1, 1919, [Convention date]. Wave energy, utilizing. -A signalling-transmitter, applicable to buoys, lighthouse, and ships, is provided with means for using the energy of the waves to generate light signals, wireless signals, or submarine sound signals. The transmitter as applied to a light-buoy consists of a tank 1 for compressed air connected to a casing 3 for a compressor and to a casing 4 in which is a differential gear on which blades 5 and 6 are mounted. The device is arranged to sound a signal bell 8, and the striking-mechanism also drives a generator to supply current for an audinn lamp 9, which may emit the light signals, and to generate oscillations in aerial 10.
