Claim 1

APPARATUS EMPOLYING SEMI-PERMEABLE MEANS FOR SEPARATING THE CONSTITUTENTS OF A FLUID FEEDMATERIAL, WHICH COMPRISES IN BOMBINATION, A. A PLURALITY OF STACKED LAMINATE MEMBERS, B. EACH LAMINTE MEMBER HAVING SEMI-PERMEABLE MEMBRANES EACH SIDE OF A CENTRAL POROUS FILLER MATERIAL WHICH PERMITS FLUID FLOW THERETHROUGH, C. SPACING MEANS IN ASSOCIATION WITH EDGE PORTIONS OF EACH LAMINATE MEMBER THEREBY FORMING INTERNAL FLUID CHANNELS BETWEEN SAID PLURALITY OF STACKED LAMINATE MEMBERS FOR THE FEED MATERIAL FLOW BETWEEN SUCH SPACED MEMBERS, D. AN IMPREGNATING FLUID SEAL MATERIAL EMBODIED INTO AND IMPREGNATED THROUGH THE ENTIRE THICKNESS OF THE END PORTIONS OF THE POROUS FILLER MATERIAL FOR EACH OF SAID LAMINATE MEMBERS TO PEVENT FLUID FLOW FROM SUCH END PORTIONS, E. A PASSAGEWAY THROUGH AT LEAST ONE ENTIRELY IMPREGNATED AND SELED END PORTION OF EACH MEMBER AND SUCH PASSAGE, WAYS IN THE PLURALITY OF MEMBERS BEING POSITIONED TO EFFECT MULTIPLE FLOW PATHS AND A RESULTING SERPENTINE EXTENDED LENGTH FLUID FLOW PATH PROVIDED THROUGH SAID INTERNAL FLUID CHANNELS BETWEEN SAID MEMBERS, F. FLUID FEED INLET MEANS TO ONE END OF SAID EXTENDED LENGTH FLOW PATH AND FLUID OUTLET MEANS FROM THE OPPOSING END THEREOF, AND G. A SEPARATED FLUID COLLECTION MEANS IN COMMUNICATION WITH THE UNSEALED POROUS AND LONGITUDINAL EDGE PORTIONS OF EACH LAMINATE MEMBER TO OBTAIN A FLUID CONSTITUENT WHICH PASSES THROUGH THE SEMI-PERMEABLE MEMBRANES OF THE LAMINATE MEMBERS TO THE POROUS FILLER MATERIAL.
