ABSTRACT:
1. A pressure responsive electrolytic detector of the character disclosed mprising a hermetically sealed casing having an electrolyte composed of a solution of iodine and potassium iodide in a solvent disposed therein, a baffle member within said casing arranged to form two fluid filled chambers on opposite sides thereof, said casing and baffle member being composed of insulating material, a pair of electrically connected inert electro-conductive anodes, each of said anodes being disposed within one of said chambers, an electro-conductive cathode having an aperture therein and arranged transversely within said baffle member, a pair of conic surfaces on said baffle member on opposite sides of said cathode and forming an aperture in contiguous abutting relation with the aperture in said cathode, said conic surfaces increasing the rate of flow of the electrolyte from one to the other of said chambers, and means on said casing responsive to acoustic signals for providing a signal detection characterized by a unidirectional electrical current flow in correlation to flow of electrolyte alternating between said chambers as an acoustic signal is received thereby.
