Voltage control system

Claim 1

IN A VOLTAGE CONTROL SYSTEM FOR A RANDOMLY VARYING LOAD IN THE FORM OF AN ELECTRIC EMULSION TREATER, THE COMBINATION OF: A.C. POWER SOURCE TERMINALS; HIGH VOLTAGE STEPUP TRANSFORMER MEANS HAVING A PRIMARY AND A SECONDARY; SATURABLE CORE REACTOR MEANS CONNECTED BETWEEN SAID SOURCE TERMINALS AND SAID PRIMARY FOR CONTROLLING POWER TRANMISSION TO SAID PRIMARY, SAID REACTOR MEANS HAVING A CONTROL WINDING AND FIRST AND SECOND VOLTAGE-CURRENT CHARACTERISTICS WITH SUBSTANTIALLY IDENTICAL AND CONSTANT VOLTAGE PORTIONS UP TO KNEES DETERMINED BY THE CONTROL WINDING CURRENT; A D.C. CURRENT SOURCE PROVIDING FIRST AND SECOND D.C. OUTPUT CURRENTS FOR OPERATING SAID REACTOR MEANS ON SAID FIRST AND SECOND CHARACTERISTICS RESPECTIVELY; CIRCUIT MEANS FOR CONNECTING SAID D.C. SOURCE TO THE CONTROL WINDING OF SAID REACTOR MEANS; A CONTAINER FOR FLUID TO BE TREATED AND INCLUDING AN INLET AND UPPER AND LOWER OUTLETS FOR FLUID FLOW THERETHROUGH; A PAIR OF ELECTRODES MOUNTED WITHIN SAID CONTAINER IN SPACED RELATION FOR FLUID FLOW THERBETWEEN; CIRCUIT MEANS FOR CONNECTING SAID SECONDARY TO SAID
