Abstract : A pressure sensitive submarine mine firing apparatus comprising an electrolytic cell including an orifice electrode communicating said chambers, means for maintaining an ion concentration gradient between said chambers, pressure sensitive means for causing the electrolyte to flow from one chamber to the other chamber through said passage means variably in accordance with the magnitude of the pressure signals applied to the apparatus, means for varying the ion concentration of the electrolyte flowing through said passage means inversely in accordance with the average magnitude of the applied pressure signals, means including said electrode for producing a signal correlative with the quantity and the ion concentration of the electrolyte flowing through said passage means, an electrolytic integrator cell in fluid communication with one of said chambers, a pair of electrodes in said integrator cell, circuit means including a source of potential connecting said orifice electrode and one of the electrodes in said integrator cell whereby the ion concentration of said integrator cell is increased in accordance with the rate of ion flow through said orifice electrode, a second circuit means including a source of potential and a firing relay connecting said pair of electrodes in said integrator cell and means for selectively shunting said relay to thereby vary the magnitude of the pressure signal necessary to actuate the relay.
