Continuous electrometric titration

Claim 1

IN A SYSTEM OF CONTINUOUS ELECTROMETRIC TITRATION, A TITRATION VESSEL, FIRST PUMP MEANS CONNECTED FOR SUPPLYING THERETO A LIQUID TO BE TITRATED, A SYNCHRONOUS MOTOR CONNECTED TO DRIVE SAID PUMP MEANS AT A CONSTANT SPEED, SECOND PUMP MEANS CONNECTED FOR SUPPLYING TO SAID VESSEL A TITRATING LIQUID, A TWO-PHASE MOTOR CONNECTED TO DRIVE SAID SECOND PUMP MEANS AT A VARIABLE SPEED, ELECTRODES IN SAID VESSEL CAPABLE OF PRODUCING A VARIABLE POTENTIAL UPON IMMERSION IN A LIQUID OF VARIBLE COMPOSITION, VOLTAGE SOURCE MEANS IN CIRCUIT WITH SAID ELECTRODES FOR BIASING SAID VARIABLE POTENTIAL, AMPLIFIER MEANS IN CIRCUIT WITH SAID ELECTRODES AND SAID BIASING VOLTAGE SOURCE FOR AMPLIFYING AND APPLYING SAID BIASED POTENTIAL TO ONE OF THE PHASE WINDINGS OF SAID TWO-PHASE MOTOR TO DRIVE SAID MOTOR, A DIRECT CURRENT GENERATOR DRIVEN BY SAID MOTOR, A RECORDER CONNECTED TO THE OUTPUT OF SAID GENERATOR, AND FEED-BACK MEANS IN CIRCUIT BETWEEN THE OUTPUT OF SAID GENERATOR AND SAID AMPLIFIER MEANS TO REGULATE THE SPEED OF SAID MOTOR AS A LINEAR FUNCTION OF THE VARIATIONS OF THE POTENTIAL BETWEEN SAID ELECTRODES.
