Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
189 words
APPARATUS FOR EFFECTING CONTACT BETWEEN A FLUID AND GRANULAR SOLIDS WHICH COMPRISES: A TANK; A STATIONARY BED OF GRANULAR CONTACTING SOLIDS SITUATED WITHIN A PORTION OF SAID TANK, SAID PORTION CONSTITUTING A SOLIDS CHAMBER AND AN ADJOINING PORTION OF SAID TANK CONSTITUTING AN ANTECHAMBER, SAID BED HAVING A SURFACE DIRECTED TOWARD SAID ANTECHAMBER AND BEING FORMED WITH A PLURALITY OF DEEP COLUMNAR DEPRESSIONS WHICH PROJECT FROM SAID SURFACE INTO SAID BED AND PROVIDE ADDITIONAL EXTENDED BED AREAS FOR THE FLOW OF FLUID BETWEEN THE BED INTERIOR AND SAID ANTECHAMBER; A MASS OF DISCRETE BODIES OF INERT MATERIAL HAVING DIAMETERS GREATER THAN THE DIAMETERS OF SAID CONTACTING SOLIDS SITUATED WITHIN EACH OF SAID DEPRESSIONS SO AS TO MAINTAN SAID DEPRESSIONS IN BEING AND THEREBY TO MAINTAIN THE SAID ADDITIONAL AREAS EXTENDED, SAID DISCRETE BODIES PROVIDING A MULTITUDE OF FLOW PASSAGES WHICH ARE IN COMMUNICATION WITH SAD ANTECHAMBER AND WITH THE LATERAL BOUNDARIES OF SAID DEPRESSIONS; AND INLET AND OUTLET MEANS FOR SAID TANK, ONE OF WHICH COMMUNICATES WITH SAID ANTECHAMBER AND THE OTHER WITH SAID SOLIDS CHAMBER FOR THE FLOW OF SAID FLUID SUCCESSIVELY THROUGH SAID CHAMBER AND THE BED.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
128 words
METHOD OF INTRODUCING A FLUID INTO A STATIONARY BED OF GRANULAR CONTACTING MATERIAL WHICH COMPRISES THE STEPS OF FLOWING SAID FLUID FIRST THROUGH PASSAGES FORMED BETWEEN DISCRETE SOLID BODIES OF DIAMETERS LARGER THAN THE GRANULES OF SAID CONTACTING MATERIAL, SAID BODIES FORMING A LAYER OF THE SURFACE OF SAID STATIONARY BED, THENCE THROUGH PASSAGES BETWEEN ADDITIONAL DISCRETE BODIES ALSO OF DIAMETERS LARGER THAN SAID GRANULES AND ARRANGED AS SUBSTANTIALLY COLUMNAR PROJECTIONS WHICH EXTEND FROM SAID SURFACE LAYER INTO THE INTERIOR OF SAID STATIONARY BED IN LATERAL CONTACT THEREWITH, AND THENCE LATERALLY FROM SAID PROJECTIONS INTO THE SAID BED, THE TOTAL ENTRY SURFACE OF SAID BED ADJOINING SAID PROJECTIONS BEING GREATER THAN THE CROSS SECTIONAL AREA OF SAID BED, WHEREBY SAID FLUID ENTERS THE BED OVER AND EXTENDED SURFACE.
