Abstract

148,431. Kayser, O. July 2, 1915, [Convention date]. Subaqueous audible signals.-Diver's armour is provided with any equipment for receiving and transmitting subaqueous sound waves. The transmitter may be in the form of a clapper, hammer, &c., struck against the wall of the armour, or may be a tuning fork or other vibratory body located outside the armour and excited by a hammer driven by clockwork controlled from the exterior or interior of the armour. A microphone or other receiving device may be employed, such as a telephone receiver.
