Apparatus for automatic dilution of measured concentrates

Claim 1

APPARATUS FOR AUTOMATIC DILUTION OF MEASURED CONCENTRATES COMPRISING, IN COMBINATION, AN INJECTOR MEMBER HAVING AN INTERIOR CAVITY, AN INPUT CHANNEL IN SAID INJECTOR MEMBER AND HAVING AT ONE END AN INJECTOR NOZZLE OPENING COMMUNICATING WITH ONE SIDE OF SAID INTERIOR CAVITY, AN OUTPUT CHANNEL IN SAID INJECTOR MEMBER AND HAVING AN OPENING AT ONE END COMMUNICATING WITH THE OTHER SIDE OF SAID INTERIOR CAVITY, A CONCENTRATE INPUT CHANNEL IN SAID INJECTOR MEMBER HAVING AN OPENING AT ONE END COMMUNICATING WITH THE INTERIOR OF SAID INTERIOR CAVITY, A CONTAINER FOR HOLDING A QUANTITY OF LIQUID CONCENTRATE, CONDUIT MEANS COMMUNICATING BETWEEN SAID CONCENTRATE INPUT CHANNEL AND THE INTERIOR OF SAID CONTAINER, INPUT CONDUIT MEANS LEADING FROM A SOURCE OF WATER UNDER PRESSURE AND COMMUNICATING WITH THE OTHER END OF SAID INPUT CHANNEL, A NORMALLY CLOSED VALVE IN SAID IMPUT CONDUIT MEANS, AND MEANS FOR AUTOMATICALLY OPENING SAID VALVE PERIODICALLY FOR AN INTERVAL OF TIME, WHEREBY WATER UNDER PRESSURE WILL BE PERIODICALLY INJECTED INTO SAID CAVITY TO PRODUCE A PARTIAL VACUUM THEREIN SERVING TO DRAW LIQUID CONCENTRATE FROM SAID CONTAINER INTO SAID CAVITY TO BE DILUTED WITH THE WATER AND DISCHARGED THROUGH SAID DISCHARGE CHANNEL, SAID CONTAINER CONTAINING A SUPPLY OF CONCENTRATE ONLY SUFFICIENT TO SUPPLY A PREDETERMINED VOLUME FOR ONE OF SAID PERIODIC TIME INTERVALS, AND MEANS FOR AUTOMATICALLY REFILLING SAID CONTAINER WITH CONCENTRATE AT EVEN RATE INTERVALS BETWEEN SAID PERIODIC TIME INTERVALS.
