Means for separating particles of high density from fluid of low density

Claim 1

AN APPARATUS FOR SEPARATING PARTICLES OF A RELATIVELY HIGH DENSITY FROM A FLUID OF LOW DENSITY IN WHICH THE PARTICLES ARE ENTRAINED COMPRISING IN COMBINATION: FIRST NOZZLE CHAMBER MEANS HAVING A CONSTANT DIAMETER TUBULAR SECTION AND A FIRST SUBSTANTIALLY FRUSTO-CONICAL NOZZLE SECTION WITH A PROGRESSIVELY DECREASING DIAMETER ENDING AT A CIRCULAR DISCHARGE OPENING AT THE SMALLER DIAMETER END THEREOF; SECOND NOZZLE CHAMBER MEANS DISPOSED DOWNSTREAM FROM SAID FIRST NOZZLE MEANS, SAID SECOND NOZZLE MEANS HAVING A SECOND SUBSTANTIALLY FRUSTO-CONICAL NOZZLE SECTION IDENTICAL TO SAID FIRST NOZZLE SECTION, REVERSED SO AS TO FACE SAID FIRST NOZZLE SECTION, AND WHEREIN SAID SECOND NOZZLE SECTION INLET OPENING HAS A DIAMETER SUBSTANTIALLY IDENTICAL TO SAID DISCHARGE OPENING, SAID SECTIONS SUBSTANTIALLY CO-AXIALLY ALIGNED AND SPACED APART A DISTANCE LESS THAN THEIR LENGTHS, AND A SEMI-CIRCULARLY FORMED REAR END MEMBER ATTACHED TO AND NORMALLY CLOSING THE LARGER DIAMETER END OF SAID SECOND NOZZLE MEANS FOR THE ATMOSPHERE; MEANS FLUIDALLY CONNECTED TO SAID SECOND NOZZLE CHAMBER MEANS REAR END MEMBER AND CAPABLE OF WITHDRAWING PARTICLES OF LOW DENSITY FROM SAID SECOND NOZZLE CHAMBER MEANS; AND DIFFUSER MEANS INCLUDING A HOLLOW FRUSTO-CONICAL SECTION A SMALLER CIRCULAR END OF WHICH MATES WITH AND IS CONNECTED TO SAID DISCHARGE END OF SAID FIRST NOZZLE SECTION, AND WHICH FRUSTO-CONICAL SECTION COMPLETELY SURROUNDS SAID SECOND NOZZLE SECTION SO AS TO FORM A CHAMBER THEREABOUT AND EXTENDS DOWNSTREAM FROM SAID CONNECTION WITH A PROGRESSIVELY INCREASING DIAMETER CONCENTRIC WITH SAID SECOND NOZZLE SECTION TO A LARGER DIAMETER TERMINAL END PAST SAID SECOND NOZZLE SECTION, A SECOND FRUSTO-CONICAL SECTION HAVING ITS LARGER DIAMETER END CONNECTED TO SAID FIRST SECTION LARGER DIAMETER TERMINAL END, AND ITS SMALLER DIAMETER END CONNECTED TO A TUBULAR SECTION HAVING AN INTERNAL DIAMETER OF SAID FIRST NOZZLE TUBULAR SECINTERNAL DIAMETER OF SAID FIRST NOZZLE TUBULAR SECTION WHEREBY THE PRESSURE OF THE DIVERTED FLUID IS RECOVERED TO A VALUE SUBSTANTIALLY EQUAL TO THE PRESSURE IN SAID CONSTANT DIAMETER SECTION OF SAID FIRST NOZZLE MEANS.

Claim 2

AN APPARATUS FOR SEPARATING PARTICLES OF A RELATIVELY HIGH DENSITY FROM A FLUID OF LOW DENSITY IN WHICH THE PARTICLES ARE ENTRAINED COMPRISING IN COMBINATION: FIRST NOZZLE CHAMBER MEANS HAVING A CONSTANT DIAMETER TUBULAR SECTION AND A FIRST SUBSTANTIALLY FRUSTO-CONICAL NOZZLE SECTION WITH A PROGRESSIVELY DECREASING DIAMETER ENDING AT A CIRCULAR DISCHARGE OPENING AT THE SMALLER DIAMETER END THEREOF; SECOND NOZZLE CHAMBER MEANS DISPOSED DOWNSTREAM FROM SAID FIRST NOZZLE MEANS, SAID SECOND NOZZLE MEANS HAVING A SECOND SUBSTANTIALLY FRUSTO-CONICAL NOZZLE SECTION IDENTICAL TO SAID FIRST NOZZLE SECTION, REVERSED SO AS TO FACE SAID FIRST NOZZLE SECTION, AND WHEREIN SAID SECOND NOZZLE SECTION INLET OPENING HAS A DIAMETER SUBSTANTIALLY IDENTICAL TO SAID DISCHARGE OPENING, SAID SECTIONS SUBSTANTIALLY CO-AXIALLY ALIGNED AND SPACED APART A DISTANCE LESS THAN THEIR LENGTHS, AND A SEMI-CIRCULARLY FORMED REAR END MEMBER ATTACHED TO AND NORMALLY CLOSING THE LARGER DIAMETER END OF SAID SECOND NOZZLE MEANS FOR THE ATMOSPHERE; MEANS FLUIDALLY CONNECTED TO SAID SECOND NOZZLE CHAMBER MEANS REAR END MEMBER AND CAPABLE OF WITHDRAWING PARTICLES OF LOW DENSITY FROM SAID SECOND NOZZLE CHAMBER MEANS; AND DIFFUSER MEANS INCLUDING A HOLLOW FRUSTO-CONICAL SECTION A SMALLER CIRCULAR END OF WHICH MATES WITH AND IS CONNECTED TO SAID DISCHARGE END OF SAID FIRST NOZZLE SECTION, AND WHICH FRUSTO-CONICAL SECTION COMPLETELY SURROUNDS SAID SECOND NOZZLE SECTION SO AS TO FORM A CHAMBER THEREABOUT AND EXTENDS DOWNSTREAM FROM SAID CONNECTION WITH A PROGRESSIVELY INCREASING DIAMETER CONCENTRIC WITH SAID SECOND NOZZLE SECTION TO A LARGER DIAMETER TERMINAL END PAST SAID SECOND NOZZLE SECTION, A SECOND FRUSTO-CONICAL SECTION HAVING ITS LARGER DIAMETER END CONNECTED TO SAID FIRST SECTION LARGER DIAMETER TERMINAL END, AND ITS SMALLER DIAMETER END CONNECTED TO A TUBULAR SECTION HAVING AN INTERNAL DIAMETER OF SAID FIRST NOZZLE TUBULAR SECINTERNAL DIAMETER OF SAID FIRST NOZZLE TUBULAR SECTION WHEREBY THE PRESSURE OF THE DIVERTED FLUID IS RECOVERED TO A VALUE SUBSTANTIALLY EQUAL TO THE PRESSURE IN SAID CONSTANT DIAMETER SECTION OF SAID FIRST NOZZLE MEANS.
