Claim 3
Dependent Claim
164 words
A PROCESS FOR FRACTIONATING AN IONIC FLUID MIXTURE INTO ITS COMPONENTS WHICH COMPRISES, CONFINING THE MIXTURE BETWEEN SUBSTANTIALLY PARALLEL SPACED SEMI-PERMEABLE FLUID BARRIERS OF ION EXCHANGE MATERIAL PASSAGE RESISTANT IN DIFFERENT DEGREES TO DIFFERENT COMPONENTS OF THE MIXTURE, SAID BARRIERS FORMING LATERAL BOUNDARIES OF FLUID COMPARTMENTS; PASSING AN ELECTRIC CURRENT THROUGH SAID BARRIERS AND THE FLUID THEREBETWEEN IN A DIRECTION SUBSTANTIALLY AT RIGHT ANGLES TO SAID BARRIRS; SUBJECTING SAID FLUID AND SAID BARRIERS TO A MECHANICAL ACCELERATING FORCE, SAID FORCE ACTING SUBSTANTIALLY PARALLEL TO THE BARRIERS; PASSING SAID FLUID MIXTURE BY FLOW IN A GENERAL DIRECTION OF THE PLANES PARALLEL TO THE BARRIERS, AND SUBSTANTIALLY AT RIGHT ANGLES TO THE DIRECTION OF THE ELECTRIC CURRENT, FROM A POINT OF INFLOW AT ONE END OF THE COMPARTMENTS TOWARDS THE OPPOSITE END OF THE COMPARTMENTS; AND WITHDRAWING FLUID AT SPACED POINTS OF THE SAME COMPARTMENTS, SAID POINTS BEING LOCATED ON VERTICALLY FANNED-OUT RADII EXTENDING FROM SAID INFOW, EACH OF SAID RADII HAVING A DIFFERENT ANULAR INCLINATION.
