Claim 1
Independent Claim
178 words
A METHOD FOR THE INTRODUCTION INTO A FLUID CONTACTING ZONE OF FLUENT SOLID PARTICLES VARYING IN SIZE OVER A RANGE SUCH THAT FLOWING A MASS OF SAID PARTICLES DOWN AN INCLINED PATH RESULTS IN A NON-UNIFORM DISTRIBUTION OF PARTICLES OF THE SAME SIZE OVER THE CROSS SECTION OF SAID MASS NORMAL TO THE DIRECTION OF FLOW, WHICH METHOD COMPRISES SUPPLYING SAID PARTICLES TO A BODY OF SAID PARTICLES LOCATED ABOVE SAID CONTACTING ZONE, DISCHARGING SAID PARTICLES FROM THE BOTTOM OF SAID BODY AT A MULTIPLICITY OF POINTS, MOVING THE PARTICLES SO DISCHARGED DOWNWARDLY IN COMPACT NONTURBULENT FLOW TO THE SURFACE OF A NON- TURBULENT BED OF SAID PARTICLES IN SAID CONTACTING ZONE AND, IN THE COURSE OF THE MOVEMENT, EXPANDING THE TOTAL HORIZONTAL AREA THROUGH WHICH SAID SOLID PARTICLES FLOW WHILE CONFINING THE OUTEMOST ANGLE OF FLOWOF SAID PARTICLES TO LESS THAN THE COMPLEMENT OF THE ANGLE OF REPOSE OF SAI PARTICLES UNTIL THE TOTAL EXPANDED AREA IS A SUBSTANTIAL PORTION OF THE HORIZONTAL AREA OF THE SURFACE OF SAID BED AND PASSING FLUID THROUGH SAID NON-TURBULENT BED.
