Galvanic primary and secondary element or cell with three electrodes

Claim 2

A PROCESS FOR THE MANUFACTURE OF THIRD ELECTRODES FOR CELLS OF THE CHARACTER DESCRIBED WHICH ARE INTENDED TO DISSOLVE IN THE ELECTROLYTE OF THE CELL, COMPRISIG COATING A PLURALITY OF NON-CONDUCTIVE FIBER FABRIC LAYER SUPPORTS WITH A PROGRESSION OF THICKNESSES RANGING FROM ABOUT ONE MICRON TO ABOUT 0.3 MM. OF CONDUCTIVE METAL, STACKING SAID FIBER FABRIC LAYER SUPPORTS IN LAYERS UPON A CORE FOIL CONSISTING OF THE SAME METAL AS THE COATING SUCH THAT SUCCESSIVELY THICKER COATED LAYERS ARE PROGRESSIVELY ARRANGED TOWARD THE CENTER CORE FOIL, CONDUCTIVELY UNITING THE STACKED LAYERS AND FOIL AND THEREAFTER SHAPING THE UNITED ASSEMBLY TO THE DESIRED ELECTRODE DIMENSIONS.

Claim 3

A GALVANIC PRIMARY AND SECONDARY CELL HAVING A HOUSING, AN ALKALINE ELECTROLYTE, A NEGATIVE ELECTRODE AND A POSITIVE ELECTRODE TOGETHER ADAPTED TO FORM A RECHARGEABLE ACCUMULATOR, THE ACTIVE MATERIAL OF SAID NEGATIVE ELECTRODE BEING COMPOSED OF A METAL SELECTED FROM THE GROUP CONSISTING OF CADMIUM OR IRON AND THE ACTIVE MATERIAL OF SAID POSITIVE ELECTRODE BEING COMPOSED OF NICKEL HYDROXIDE, A THIRD ELECTRODE OF METAL SOLUBLE IN SAID ALKALINE ELECTROLYTE AND INTERPOSED BETWEEN SAID NEGATIVE AND POSITIVE ELECTRODES, THE ACTIVE MATERIAL OF SAID THIRD ELECTRODE BEING COMPOSED OF A METAL SELECTED FROM THE GROUP CONSISTING OF ALUMINUM AND ZINC, ELECTRICALLY NONCONDUCTIVE SEPARATORS BETWEEN THE ELECTRODES AND WITHIN THE CASING TO PREVENT DIRECT ELECTRICAL CONTACT OF ANY TWO OF THE THREE SAID ELECTRODES WITH EACH OTHER, SAID THIRD ELECTRODE FORMING A GALVANIC PRIMARY ELEMENT WITH ONE OF SAID POSITIVE AND NEGATIVE ELECTRODES WHICH DISCHARGES ELECTRICAL ENERGY DURING DISSOLUTION OF SAID THIRD ELECTRODE IN SAID ELECTROLYTE, THE SAID POSITIVE AND NEGATIVE ELECTRODES THEREAFTER IN THE SAME ELECTROLYTE BEING DISCHARGEABLE ADDITIONALLY AS A SECONDARY CELL, A SEPARATE TERMINAL FOR EACH OF SAID POSITIVE, NEGATIVE AND THIRD ELECTRODES EXTERNAL OF THE HOUSING TO WHICH EACH OF THE ELECTRODES IS RESPECTIVELY CONNECTED, SO THAT PRIMARY CELL POWER MAY BE DERIVED FROM THE CELL FIRST BY CONNECTION TO THE TERMINAL OF THE THIRD ELECTRODE AND THE TERMINAL OF ONE OF THE OTHER TWO ELECTORDES AND SECONDARY CELL POWER MAY BE DERIVED FROM THE CELL THEREAFTER UPON COMPLETION OF DISSOLUTION OF THE THIRD ELECTRODE BY CONNECTION TO THE TERMIANLS OF THE POSITIVE AND NEGATIVE ELECTRODES.

Claim 4

A GALVANIC PRIMARY AND SECONDARY CELL HAVING A HOUSING, AN ALKALINE ELECTROLYTE, A NEGATIVE ELECTRODE AND A POSITIVE ELECTRODE TOGETHER ADAPTED TO FORM A RECHARGEABLE ACCUMULATOR, THE ACTIVE MATERIAL OF SAID NEGATIVE ELECTRODE BEING COMPOSED OF A METAL SELECTED FROM THE GROUP CONSISTING OF CADMIUM OR IRON AND THE ACTIVE MATERIAL OF SAID POSITIVE ELECTRODE BEING COMPOSED OF NICKEL HYDROXIDE, A THIRD ELECTRODE OF METAL SOLUBLE IN SAID ALKALINE ELECTROLYTE AND INTERPOSED BETWEEN SAID NEGATIVE AND POSITIVE ELECTRODES, THE ACTIVE MATERIAL OF SAID THIRD ELECTRODE BEING COMPOSED OF A METAL SELECTED FROM THE GROUP CONSISTING OF ALUMINUM AND ZINC, ELECTRICALLY NONCONDUCTIVE SEPARATORS BETWEEN THE ELECTRODES AND WITHIN THE CASING TO PREVENT DIRECT ELECTRICAL CONTACT OF ANY TWO OF THE THREE SAID ELECTRODES WITH EACH OTHER, SAID THIRD ELECTRODE FORMING A GALVANIC PRIMARY ELEMENT WITH ONE OF SAID POSITIVE AND NEGATIVE ELECTRODES WHICH DISCHARGES ELECTRICAL ENERGY DURING DISSOLUTION OF SAID THIRD ELECTRODE IN SAID ELECTROLYTE, THE SAID POSITIVE AND NEGATIVE ELECTRODES THEREAFTER IN THE SAME ELECTROLYTE BEING DISCHARGEABLE ADDITIONALLY AS A SECONDARY CELL, A SEPARATE TERMINAL FOR EACH OF SAID POSITIVE, NEGATIVE AND THIRD ELECTRODES EXTERNAL OF THE HOUSING TO WHICH EACH OF THE ELECTRODES IS RESPECTIVELY CONNECTED, SO THAT PRIMARY CELL POWER MAY BE DERIVED FROM THE CELL FIRST BY CONNECTION TO THE TERMINAL OF THE THIRD ELECTRODE AND THE TERMINAL OF ONE OF THE OTHER TWO ELECTORDES AND SECONDARY CELL POWER MAY BE DERIVED FROM THE CELL THEREAFTER UPON COMPLETION OF DISSOLUTION OF THE THIRD ELECTRODE BY CONNECTION TO THE TERMIANLS OF THE POSITIVE AND NEGATIVE ELECTRODES.
