Mechanical orientation of magnetically anisotropic particles

Claim 1

A METHOD OF IMPROVING THE SHEETING CHARACTERISTICS OF MIXTURE OF UNCURED RUBBER AND ULTRAFINE PARTICLES OF SUBSTANTIALLY DOMAIN SIZE BARIUM FERRITE WHEREIN THE FERRITE PARTICLES COMPRISE ABOUT 55-70% OF THE TOTAL VOLUME OF THE MIXTURE, SAID METHOD COMPRISING SUBDIVIDING SAID MIXTURE INTO GRANULES SMALL ENOUGH TO PASS A 20 MESH SCREEN, AND THEREAFTER FORMING A PLURALITY OF SAID GRANULES IN THE SOLID STATE INTO A SHEET BY ROLLING SAID GRANULES UNDER PRESSURE BETWEEN ROLLS, SAID GRANULES THEREBY BEING FORMED INTO A COHERENT UNIFORM CONTINUOUS SHEET MORE READILY THAN SAID MIXTURE CAN BE IN THE ABSENCE OF SUCH SUBDIVISION.
