Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
168 words
IN AN AUTOMATIC TITRATING MECHANISM FOR THE QUANTITATIVE DETERMINATION OF A FIRST REACTANT IN A FLUID, THE COMBINATION WHICH COMPRISES A CELL INTO WHICH THE FLUID IS INTRODUCED, ELECTROLYTIC MEANS FOR GENERATING A SECOND REACTANT FOR REACTION TO AN END POINT IN THE CELL WITH THE FIRST REACTANT, END POINT SENSING MEANS IN OPERATIVE ASSOCIATION WITH THE CELL FOR PRODUCING A POTENTIAL DIFFERENCE WHICH CHANGES AS THE EXCESS OF ONE OF THE REACTANTS IN THE CELL CHANGES FROM THE END POINT, AN ELECTRONIC POWER AMPLIFIER OF HIGH TRANSCONDUCTANCE HAVING ITS INPUT CONNECTED TO THE END POINT SENSING MEANS AND ITS OUTPUT CONNECTED TO THE ELECTROLYTIC MEANS TO SUPPLY POWER THERETO FOR GENERATING THE SECOND REACTANT AND SO ARRANGED THAT ITS OUTPUT CURRENT VARIES IN RESPONSE TO THE CHANGE IN THE POTENTIAL DIFFERENCE, AND MEANS INCLUDING A REACTIVE CIRCUIT CONNECTED BETWEEN THE END POINT SENSING MEANS AND THE ELECTROLYTIC MEANS FOR MORE STRONGLY ATTENUATING HIGH FREQUENCY COMPONENTS OF THE AMPLIFIER INPUT THAN LOW FREQUENCY COMPONENTS OF THE AMPLIFIER INPUT.
