Magnetic-restrictive separator

Claim 1

A MAGNETIC-RESTRICTIVE SEPARATOR ADAPTED TO SEPARATE FERROUS AND NON-FERROUS PARTICLES FROM A FLUID, COMPRISING AN EXTERNAL CASING HAVING PORTS THEREIN FOR THE RECEPTION AND DISCHARGE OF SAID FLUID, A STACK OF COAXIAL, GENERALLY FRUSTO-CONICAL OPPOSING ANNULAR MAGNETIZABLE GRIDS DISPOSED IN SAID CASING IN PAIRED RELATIONSHIP SO AS TO DEFINE AN ANNULAR CHAMBER BETWEEN SAID PAIRED GRIDS AND THE WALLS OF SAID CASING AND A SPACE IN THE INTERIOR OF SAID STACK, SAID CHAMBER AND SAID SPACE COMMUNICATING RESPECTIVELY WITH SAID PORTS, SAID STACK INCLUDING FLUID PERMEABLE, INTERNAL GRID SUPPORT MEANS EXTENDING BEYOND THE ENDS OF SAID STACK WITH MEANS THEREON TO LOOSELY RETAIN SAID GRIDS WHEN SAID SEPARATOR IS DISASSEMBLED, SAID GRIDS BEING FREELY SEPARABLE FROM EACH OTHER WHEN SAID STACK IS REMOVED WHEREBY BOTH SIDES OF SAID GRID ARE ACCESSIBLE FOR CLEANING WHILE AT THE SAME THE GRIDS ARE MAINTAINED IN THEIR PREDETERMINED ORDER, SAID STACK BEING DISPOSED IN SAID CASING SO AS TO PERMIT SAID FLUID TO FLOW IN A GENERALLY RADIAL DIRECTION BETWEEN SAID CHAMBER AND SAID SPACE AND IN PARALLEL PATHS THROUGH SAID GRIDS, AND MAGNETIC MEANS IN SAID CASING AT OPPOSITE ENDS OF SAID STACK FOR MAGNETIZING SAID GRIDS, SAID MAGNETIC MEANS BEING IN RELEASABLE ARRANGEMENT WITH SAID STACK AND SUPPORT MEANS WHEREBY SAID STACK AND SUPPORT MEANS CAN BE REMOVED FROM THE INFLUENCE OF SAID MAGNETIC MEANS WITHOUT THE NEED FOR DISASSEMBLING SAID GRIDS, SAID GRIDS BEING COMPRESSED BETWEN SAID MAGNETS AND HAVING SUFFICIENT RIGIDITY TO GENERALLY PRESERVE SAID FRUSTO-CONICAL SHAPE; SAID MAGNETIZATION OF SAID GRIDS AND THE INTERSTITIAL CHARACTER THEREOF BEING ADAPTED TO SEPARATE SAID FERROUS AND NON-FERROUS PARTICLES FROM SAID FLUID.
