Abstract

123,937. Gill, J. H. W. Oct. 14, 1918. Locating subaqueous sounds.-Relates to hydrophones having a diaphragm exposed on both sides to the water but with a screen on one side to reduce the intensity of the sound received on that side to enable the direction of the source of the sound to be determined, the screen comprising a double walled water-tight plate containing loose metallic balls such as lead shot. According to the invention, the lead shot D is arranged loosely in cells B' the sides of which support the walls A, C against the water pressure, thereby preventing the walls from pressing on the shot.
