Abstract

151,277. M:eine, B. Sept. 19, 1919, [Convention date]. Locating sounds.-The bearing of an audible signal sent out from a ship is determined by means of microphones m1 - - m9 arranged along the shore of a channel and connected in groups to a number of oscillographs, having a common recording-strip. The bearing as determined by the times of arrival of the sound, or by the differences in times of arrival through water and through air, may be communicated to the ship by wireless. A switching-device, Fig. 2, is arranged to allow any particular set of five microphones to be connected to the five oscillographs of the recording-instrument. This switch has five sets k1 - - k5 of five contacts, each set communicating with five of the microphone circuits I - - IX.
