Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
109 words
A PROCESS OF SEPARATING, IN THE FORM OF AGGLOMERATES, ONE OR MORE SUBSTANTIALLY SOLID MATERIALS FROM A LIQUID SUSPENSION THEREOF, SAID PROCESS COMPRISING: (A) INTRODUCING SAID LIQUID SUSPENSION INTO A PRE(B) FORMING AGGLOMERATION NUCLEI OF SAID SOLID MATERIALS BY PRODUCING IN SAID PRELIMINARY ZONE A TURBULENCE STRONG ENOUGH TO FINELY DIVIDE SAID MATERIALS CONTAINED IN THE SUSPENSION; (C) SUBSEQUENTLY PASSING THE SESULTING SUSPENSION OF SAID NUCLEI IN THE LIQUID INTO AN AGGLOMERATION ZONE; (D) PRODUCING AGGLMERATES FROM SAID NUCLEI WHICH HAVE BEEN PASSED INTO SAID AGGLOMERATION ZONE BY SUBJECTING SAID NUCLEI TO A UNIFORM GENTLE AGITATION OF SUBSTANTIALLY LESS MAGNITUDE THAN THE STRONG TURTULENCE PRODUCED IN SAID PRELIMINARY ZONE.
Claim 2
Dependent Claim
109 words
A PROCESS OF SEPARATING, IN THE FORM OF AGGLOMERATES, ONE OR MORE SUBSTANTIALLY SOLID MATERIALS FROM A LIQUID SUSPENSION THEREOF, SAID PROCESS COMPRISING: (A) INTRODUCING SAID LIQUID SUSPENSION INTO A PRE(B) FORMING AGGLOMERATION NUCLEI OF SAID SOLID MATERIALS BY PRODUCING IN SAID PRELIMINARY ZONE A TURBULENCE STRONG ENOUGH TO FINELY DIVIDE SAID MATERIALS CONTAINED IN THE SUSPENSION; (C) SUBSEQUENTLY PASSING THE SESULTING SUSPENSION OF SAID NUCLEI IN THE LIQUID INTO AN AGGLOMERATION ZONE; (D) PRODUCING AGGLMERATES FROM SAID NUCLEI WHICH HAVE BEEN PASSED INTO SAID AGGLOMERATION ZONE BY SUBJECTING SAID NUCLEI TO A UNIFORM GENTLE AGITATION OF SUBSTANTIALLY LESS MAGNITUDE THAN THE STRONG TURTULENCE PRODUCED IN SAID PRELIMINARY ZONE.
Claim 3
Dependent Claim
207 words
APPARATUS FOR SEPARATING, IN THE FORM OF AGGLOMERATES, ONE OR MORE SUBSTANTIALLY SOLID MATERIALS FROM A LIQUID SUSPENSION THEREOF, SAID APPARATUS COMPRISING: (A) A VERTICAL, OPEN-TOPPED, CLOSED BOTTOM, GENERALLY CYLINDRICAL CASING MEANS FOR CONTAINING SAID LIQUID SUSPENSION; (B) INLET MEANS LOCATED NEAR THE BOTTOM OF SAID CASING FOR INTRODUCING SAID LIQUID SUSPENSION THERETO; (C) OUTLET MEANS LOCATED NEAR THE TOP OF SAID CASING FOR DISCHARGING LIQUID AND AGGLOMERATES SEPARATED FROM SAID SUSPENSION; (D) ROTATABLE SHAFT MEANS CENTRALLY MOUNTED ON THE BOTTOM OF SAID CASING AND EXTENDING VERTICALLY THROUGHOUT THE LENGTH OF SAID CASING TO POINT ABOVE THE TOP OF SAID CASING; (E) SCRAPER MEANS MOUNTED ON THE LOWER END OF SAID SHAFT FOR PREVENTING SUSPENDED MATERIAL FROM SETTLING ON THE BOTTOM OF SAID CASING; (F) AGITATOR MEANS MOUNTED ON THE LOWER END OF SAID SHAFT AND AT A LOCATION ABOVE SAID SCRAPER MEANS; SAID AGITATOR MEANS BEING CAPABLE, UPON ROTATION OF SAID SHAFT, OF PRODUCING A FIRST ZONE OF STRONG TURBULENCE FOR FINELY DIVIDING THE SOLID MATERIALS OF SAID SUSPENSION INTO AGGLOMERATE NUCLEI; AND (G) ROTOR MEANS MOUNTED ON SAID SHAFT AT A LOCATION ABOVE SAID AGITATOR MEANS FOR PRODUCING AN ELONGATED SECOND ZONE OF UNIFORMLY GENTLE AGITATION THROUGHOUT THE LENGTH OF SAID SECOND ZONE UPON R
