Magnetic drum separator and tank therefor

Claim 1

A MAGNETC DRUM SEPARATOR COMPRISING, IN COMBINATION, A DRUM, MEANS SUPPORTING SAID DRUM FOR ROTATION, A MAGNETIC CIRCUIT SUPPORTED ADJACENT TO AND LIMITED GENERALLY TO AN ARCUATE PORTION OF SAID DRUM, TANK WALL MEANS ARRANGED IN OPPOSED RELATION WITH A PORTION OF SAID ARCUATE PORTION OF SAID DRUM AND EXTENDING AT AN ANGLE TO THE HORIZONTAL TO AND BEYOND THE VERTICAL CENTERLINE OF SAID DRUM, SAID WALL MEANS SPACED FROM SAID DRUM BUT DISPOSED IN THE MAGNETIC FIELD OF SAID MAGNETIC CIRCUIT TO DEFINE, WITH SAID DRUM, A PASSAGE FOR CONFINING A LIQUID MEDIA WITHIN THE MAGNETIC FIELD SAID TANK WALL INCLUDING A PORTION EXTENDING FROM SAID CENTERLINE GENERALLY DOWNWARDLY AND AWAY FROM SAID DRUM WITH SAID PORTION BEING CURVED ON A RADIUS LOCATED BELOW SAID PORTION TO FORM A GRADUALLY DOWNWARDLY CURVED LIP, SAID PORTION AND AT LEAST 10 DEGREES OF THE SURFACE OF SAID DRUM FORMING A DIVERGENT NOZZLE TYPE CONTOUR TO EFFECT A PHYSICAL SEPARATION OF THE MAGNETIC AND NON-MAGNETIC PORTIONS OF SAID LIQUID MEDIA WHILE CONTROLLING THE FLOW OF SAID LIQUID MEDIA AND THROUGH SAID POINT OF PHYSICAL SEPARATION TO INCREASE ITS EXPOSURE TO SAID MAGNETIC FIELD AND REDUCE THE AMOUNT OF TUBULENCE AT THE POINT OF PHYSICAL SEPARATION, AND MEANS SPACED VERTICALLY ABOVE SAID TANK WALL ADJACENT THE TERMINATION OF SAID MAGNETIC CIRCUIT AND SAID DRUM TO RECEIVE SAID MAGNETIC PORTIONS AS THEY LEAVE THE INFLUENCE OF THE MAGNETIC FIELD OF SAID MAGNETIC CIRCUIT AND SEPARATE FROM SAID DRUM.
