Electronically controlled flow diverting apparatus for maintaining a predetermined solution concentration

Claim 1

ELECTRICALLY CONTROLLED APPARATUS FOR MAINTAINING A PREDETERMINED CONCENTRATION IN AN ELECTRICALLY CONDUCTIVE SOLUTION, SAID APPARATUS COMPRISING A CONCENTRATE TANK ADAPTED TO CONTAIN A CONCENTRATED LIQUID SOLUTION, A LIQUID SUPPLY LINE DIRECTED TO DISCHARGE A STREAM OF LIQUID UNDER PRESSURE DIRECTLY INTO SAID TANK WITH THE DISCHARGE END THEREOF SPACED FROM SAID TANK AND DISPOSED ABOVE THE LIQUID LEVEL THEREIN, A SHIFTABLE DEFLECTOR ELEMENT NORMALLY OPPOSED TO THE DISCHARGE END OF SAID SUPPLY LINE, YIELDABLE MEANS NORMALLY HOLDING SAID DEFLECTOR ELEMENT IN DEFLECTING POSITION TO NORMALLY PREVENT THE DISCHARGE THEREFROM FROM FLOWING INTO SAID TANK, A CONTROL SYSTEM INCLUDING A DETECTOR RESPONSIVE TO THE CONCENTRATION OF A LIQUID SOLUTION AND ADAPTED TO BE ACTURATED ONLY WHEN THE SOLUTION VARIES FROM A PREDETERMINED CONCENTRATION, AN ELECTRORESPONSIVE ACTUATING MEMBER ELECTRICALLY CONNECTED WITH SAID CONTROL SYSTEM FOR ACTUATION THEREBY AND MECHANICALLY CONNECTED WITH SAID DEFLECTOR ELEMENT TO SHIFT THE SAME OUT OF DEFLECTING POSITION WHEN ACTUATED BY THE CONTROL SYSTEM TO PERMIT THE STREAM OF LIQUID UNDER PRESSURE TO BE DISCHARGED DIRECTLY INTO THE TANK TO OVERFLOW THE SAME, AND MEANS AFFORDING OVERFLOW COMMUNICATION BETWEEN THE TANK AND THE SOLUTION BEING CONTROLLED.
