THE PROCESS OF SEPARATING FRAGMENTS OF MATERIALS OF DIFFERENT THERMAL CONDUCTIVITIES COMPRISING THE STEPS OF HEATING A MIXTURE OF SAID FRAGMENTS TO A SUBSTANTIALLY UNIFORM DEGREE, THEN COOLING SAID FRAGMENTS TO A SUBSTANTIALLY UNIFORM DEGREE, THEN COOLING SAID FRAGMENTS FOR A RELATIVELY SHORT PERIOD OF TIME WHEREUPON THE BETTER HEATCONDUCTIVE FRAGMENTS DISSIPATE THEIR HEAT FASTER THAN THE POORER HEAT-CONDUCTIVE MATERIALS, THEREBY PRODUCING A DIFFERENTIALLY HEATED MIXTURE OF FRAGMENTS, THEN PLACING THE MIXTURE IN CONTACT WITH A THERMOPLASTIC SURFACE, WHEREUPON THE FRAGMENTS OF THE MIXTURE TENT OT ADHERE THERETO TO DIFFERENT DEGREES, AND THEREUPON SEPARATELY REMOVING FROM SAID SURFACE THE FRAGMENTS ACCORDING TO THEIR TENDENCIES TO ADHERE THERETO.
