Mixing apparatus

Claim 1

MECHANISM FOR AUTOMATICALLY MIXING CONTROLLED AMOUNTS OF A FIRST FLUID WITH A SECOND FLUID COMPRISING SUPPLY MEANS THROUGH WHICH THE SECOND FLUID IS ADAPTED TO FLOW TOWARD A UTILIZATION REGION, A RESERVOIR, MEANS TO FEED THE FIRST FLUID INTO THE RESERVOIR AND TO PRECLUDE ANY REVERSE FLOW THEREOF, MEANS TO CONTROL AND MODIFY THE RESERVOIR VOLUME INSTANTANEOUSLY AVAILABLE TO THE FIRST FLUID, A PROBE MEANS INCLUDED IN THE FLOW PATH OF THE SECOND FLUID FOR DIVERTING MINUTE PORTIONS OF THE SAID SECOND FLUID, SAID PROBE MEANS HAVING A PAIR OF TUBULAR FLUID PASSAGES THEREIN WITH AN OPENING TO ONE PASSAGE BEING FACED TOWARD THE DIRECTION OF FLOW OF THE SECOND FLUID AND WITH AN OPENING INTO THE OTHER PASSAGE FACED FROM THE DIRECTION OF FLOW OF THE SAID SECOND FLUID AND SHIELDED FROM THE FLOW PATH BY THE PROBE, TUBULAR MEANS HAVING TWO INDEPENDENT FLUID-DIRECTING PASSAGES THERETHROUGH, MEANS TO ESTABLISH A COMMUNICATING RELATIONSHIP BETWEEN THE TUBULAR PASSAGE OF THE PROBE MEANS FACING THE FLOW PATH OF THE SECOND FLUID AND A FIRST END OF ONE OF THE FLUID-DIRECTING PASSAGES, MEANS TO ESTABLISH A COMMUNICATING RELATIONSHIP BETWEEN THE SECOND END OF THE SAID ONE OF THE FLUID-DIRECTING PASSAGES AND THE RESERVOIR VOLUME CONTROL MEANS TO SUPPLY THE DIVERTED SECOND FLUID INTO THE SAID RESERVOIR VOLUME CONTROL MEANS, THEREBY TO REDUCE THE VOLUME OF THE FIRST FLUID WITHIN THE RESERVOIR AT A RATE SUBSTANTIALLY PROPORTIONAL TO THE INSTANTANEOUS VELOCITY AND PRESSURE CONDITION OF THE SECOND FLUID, MEANS TO ESTABLISH A CONNECTION BETWEEN ONE END OF THE OTHER ONE OF THE INDEPENDENT FLUID-DIRECTING PASSAGES AND THE RESERVOIR FOR SUPPLYING THERETO FROM THE RESERVOIR A VOLUME OF THE FIRST FLUID WHICH IS PROPORTIONAL TO THE RESERVOIR VOLUME CHANGE, MEANS TO ESTABLISH A COMMUNICATING RELATIONSHIP BETWEEN THE SECOND END OF THE SECOND FLUID-DIRECTING PASSAGE WITHIN THE TUBULAR MEANS AND THE TUBULAR PASSAGE WITHIN THE PROBE FACING AWAY FROM THE DIRECTION OF FLOW OF THE SECOND FLUID FOR FEEDING THE CONTROLLED VOLUME OF THE FIRST FLUID OUTWARDLY FROM THE SAID TUBULAR MEANS FOR MIXING WITH THE SECOND FLUID IN A REGION OF REDUCED PRESSURE RELATIVE TO THE PRESSURE DEVELOPED IN THE FIRST PASSAGE WITHIN THE PROBE, AND MEANS TO PRECLUDE FLOW OF THE SECOND FLUID THROUGH THE SECOND PASSAGE WITHIN THE TUBULAR MEMBER TOWARD THE RESERVOIR.
