Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
130 words
A METHOD FOR MAKING A POLAROGRAPHIC DETERMINATION, WHICH COMPRISES CONTINUOUSLY DRAWING AN ELECTRICALLY CONDUCING WIRE AT A CONSTANT RATE THROUGH A PREPOLARIZING ZONE AND THEREAFTER THROUGH A MEASURING CELL CONTAINING AN ELECTROLYTIC TEST SOLUTION, APPLYING A GRADUALLY INCREASING VOLTAGE TO SAID WIRE AS IT PASSES THROUGH SAID PREPOLARIZING ZONE, APPLYING A SUBSTANTIALLY EQUAL GRADUALLY INCREASING VOLTAGE TO SAID WIRE AS IT PASSES THROUGH SAID MEASURING CELL SO THAT CURRENT CONDUCTED THROUGH THE WIRE IN THE MEASURING CELL DUE TO CAUSES OTHER THAN ELECTROREACTION OF MATERIAL UNDERGOING INVESTIGATION IN SAID TEST SOLUTION IS PRACTIALLY NEGLIGIBLE, CONTINUOUSLY FLOWING SAID TEST SOLUTION THROUGH SAID MEASURING CELL OVER A CONSTANT EXPOSED SURFACE OF WIRE PASSING THERETHROUGH AND RECORDING THE CHANGE IN CURRENT OF THE WIRE IN SAID MEASURING CELL WITH CHANGE IN APPLIED VOLTAGE.
Claim 2
Independent Claim
130 words
A METHOD FOR MAKING A POLAROGRAPHIC DETERMINATION, WHICH COMPRISES CONTINUOUSLY DRAWING AN ELECTRICALLY CONDUCING WIRE AT A CONSTANT RATE THROUGH A PREPOLARIZING ZONE AND THEREAFTER THROUGH A MEASURING CELL CONTAINING AN ELECTROLYTIC TEST SOLUTION, APPLYING A GRADUALLY INCREASING VOLTAGE TO SAID WIRE AS IT PASSES THROUGH SAID PREPOLARIZING ZONE, APPLYING A SUBSTANTIALLY EQUAL GRADUALLY INCREASING VOLTAGE TO SAID WIRE AS IT PASSES THROUGH SAID MEASURING CELL SO THAT CURRENT CONDUCTED THROUGH THE WIRE IN THE MEASURING CELL DUE TO CAUSES OTHER THAN ELECTROREACTION OF MATERIAL UNDERGOING INVESTIGATION IN SAID TEST SOLUTION IS PRACTIALLY NEGLIGIBLE, CONTINUOUSLY FLOWING SAID TEST SOLUTION THROUGH SAID MEASURING CELL OVER A CONSTANT EXPOSED SURFACE OF WIRE PASSING THERETHROUGH AND RECORDING THE CHANGE IN CURRENT OF THE WIRE IN SAID MEASURING CELL WITH CHANGE IN APPLIED VOLTAGE.
Claim 3
Dependent Claim
103 words
AN ELECTRODE SYSTEM ADAPTED FOR POLAROGRAPHIC ANALYSIS COMPRISING AN ELECTRICALLY CONDUCTING WIRE, A PREPOLARIZING CELL, A MEASURING CELL, MEANS FOR CONTINUOUSLY DRAWING SAID WIRE AT A CONSTANT RATE SUCCESSIVELY THROUGH SAID PREPOLARIZING CELL AND SAID MEASURING CELL, MEANS FOR APPLYING VOLTAGE TO SAID WIRE DURING PASSAGE THEREOF THROUGH SAID PREPOLARIZING CELL, MEANS FOR CONTINUOUSLY AGE TO SAID MEASURING CELL AND MEANS FOR CONTINUOUSLY FLOWING AN ELECTROLYTIC TEST SOLUTION THROUGH SAID MEASURING CELL OVER A CONSTANT EXPOSED SURFACE AREA OF SAID WIRE PASSING THERETHROUGH WHEREBY CURRENT FLOWING THROUGH SAID WIRE IN SAID MEASURING CELL IS ATTRIBUTABLE SOLELY TO ELECTROREACTION OCCURING IN SAID TEST SOLUTION.
Claim 4
Dependent Claim
