Electrode measuring device

Claim 1

A DEVICE FOR DETERMINING THE CONTENT OF DISSOLVED REDUCIBLE GAS IN A SOLUTION COMPOSED OF AT LEAST ONE REDUCIBLE GAS IN A LIQUID, COMPRISING, ELECTROLYTIC CELL MEANS INCLUDING A PAIR OF SPACED ELECTRODES, ONE OF SAID SPACED ELECTRODES BEING A REFERENCE ELECTRODE AND THE OTHER A MEASURING ELECTRODES, AN ALKALINE ELECTROLYTE BRIDGING SAID SPACED ELECTRODES, SAID ELECTROLYTE HAVING A CONSTITUENT IDENTICAL WITH THE SUBSTANCE FORMED AT THE MEASURING ELECTRODE AND CONSUMED IN CHEMICALLY EQUIVALENT QUANTITY AT THE REFERENCE ELECTRODE OF SAID SPACED ELECTRODES, A MEMBRANE FOR ENCASING SAID SPACED ELECTRODES AND SAID ELECTROLYTE AND FOR SEPARATING FROM SOLUTION SAID DISSOLVED REDUCIBLE GAS IN SAID SOLUTION FROM SAID DISSOLVED SALTS IN THE SAME SOLUTION, SAID MEMBRANE BEING GAS PERMEABLE TO SAID DISSOLVED REDUCIBLE GAS IN SAID SOLUTION BUT NON-PERMEABLE TO SAID DISSOLVED SALTS IN SAID SOLUTION, AND AN ELECTRIC CIRCUIT INCLUDING A SOURCE OF POTENTIAL FOR SAID SPACED ELECTRODES AND A TEMPERATURE COMPENSATING DEVICE ELECTRICALLY ASSOCIATED WITH SAID ELECTROLYTIC CELL MEANS FOR ABETTING AND DETECTING AN ELECTRICAL CHANGE IN SAID ELECTROLYTIC CELL MEANS RESULTING FROM THE REDUCTION OF THE DISSOLVED REDUCIBLE GAS WHICH PASSES THROUGH SAID MEMBRANE INTO SAID ELECTROLYTIC CELL MEANS, WITH SAID TEMPERATURE COMPENSATING DEVICE COMPENSATING FOR CHANGES IN TEMPERATURE IN THE ENVIRONMENT OF SAID MEMBRANE.

Claim 2

A DEVICE FOR DETERMINING THE CONTENT OF DISSOLVED REDUCIBLE GAS IN A SOLUTION COMPOSED OF AT LEAST ONE REDUCIBLE GAS IN A LIQUID, COMPRISING, ELECTROLYTIC CELL MEANS INCLUDING A PAIR OF SPACED ELECTRODES, ONE OF SAID SPACED ELECTRODES BEING A REFERENCE ELECTRODE AND THE OTHER A MEASURING ELECTRODES, AN ALKALINE ELECTROLYTE BRIDGING SAID SPACED ELECTRODES, SAID ELECTROLYTE HAVING A CONSTITUENT IDENTICAL WITH THE SUBSTANCE FORMED AT THE MEASURING ELECTRODE AND CONSUMED IN CHEMICALLY EQUIVALENT QUANTITY AT THE REFERENCE ELECTRODE OF SAID SPACED ELECTRODES, A MEMBRANE FOR ENCASING SAID SPACED ELECTRODES AND SAID ELECTROLYTE AND FOR SEPARATING FROM SOLUTION SAID DISSOLVED REDUCIBLE GAS IN SAID SOLUTION FROM SAID DISSOLVED SALTS IN THE SAME SOLUTION, SAID MEMBRANE BEING GAS PERMEABLE TO SAID DISSOLVED REDUCIBLE GAS IN SAID SOLUTION BUT NON-PERMEABLE TO SAID DISSOLVED SALTS IN SAID SOLUTION, AND AN ELECTRIC CIRCUIT INCLUDING A SOURCE OF POTENTIAL FOR SAID SPACED ELECTRODES AND A TEMPERATURE COMPENSATING DEVICE ELECTRICALLY ASSOCIATED WITH SAID ELECTROLYTIC CELL MEANS FOR ABETTING AND DETECTING AN ELECTRICAL CHANGE IN SAID ELECTROLYTIC CELL MEANS RESULTING FROM THE REDUCTION OF THE DISSOLVED REDUCIBLE GAS WHICH PASSES THROUGH SAID MEMBRANE INTO SAID ELECTROLYTIC CELL MEANS, WITH SAID TEMPERATURE COMPENSATING DEVICE COMPENSATING FOR CHANGES IN TEMPERATURE IN THE ENVIRONMENT OF SAID MEMBRANE.
