Inert voltaic batteries

Claim 1

AN INERT DRY BATTERY FOR ACTIVATION BY IMMERSION IN SaLT WATER IN A SUBSTANTIALLY UPRIGHT POSITION COMPRISING A GENERALLY CLOSED BATTERY CONTAINER INCLUDING A TOP HAVING A VENT THEREIN AND A BOTTOM, A PLURALITY OF CELL CONTAINERS WITHIN SAID BATTERY CONTAINER EACH HAVING A WIDE OPEINING AT ITS UPPER END SPACED BELOW THE TOP OF SAID BATTERY CONTAINER AND HAVING AN OVERFLOW OPENING A LITTLE BELOW ITS UPPER END A DUCT EXTENDING FROM ABOVE THE TOP OF THE BATTERY CONTAINER DOWN TO A POINYT WITHIN THE BATTERY CONTAINER OUTSIDE SAID CELL CONTAINERS AND BELOW THE LEVEL OF THE OVERFLOW OPENINGS IN SAID CELL CONTAINERS, SAID DCUT SERVING AS AN INLET FOR WATER WHEN THE BATTERY IS FIRST IMMERSED AND SUBSEQUENTLY AS AN OUTLET FOR EXCESS GAS AND LIQUID, A PLURALITY OF ELEMENTS WITHIN EACH CELL CONTAINER WHICH WHEN SaLT WATER IS ADDED TO THE CONTAINER, CONSTITUE THEREIN A VOLTAIC CELL AND ALSO GENERATE GAS, A POROUS MEMBRANE ACROSS SAID VENT WHICH WHEN DRY PERMITS THE PASSAGE OF GAS BUT WHEN WET PREVENTS THE PASSAGE OF GAS, A WATER REPELLENT BARRIER TO PERMIT THE PASSAGE OF GAS LOCATED OUTSIDE SAID MEMBRANE TO PREVENT ACCESS OF WATER TO THE MEMBRANE FROM OUTSIDE THE BATTERY CONTAINER WHEN THE BATTERY IS IMMERSED, SAID MEMBRANE THUS BECOMING WET AFTER THE BATTERY IS IMMERSED ONLY WHEN THE BATTERY CONTAINER FILLS SUFFICIENTLY FOR WATER TO REACH THE MEMBRANE FROM THE INSIDE OF THE BATTERY CONTAINER AND THEREAFTER PREVENTING THE ESCAPE OF GAS THROUGH THE VENT AND THE PRESSURE OF THE GAS GENERATED BY THE ACCESS OF THE WATER
