Toroidal core pressure forming method

Claim 1

METHOD FOR PRODUCING A TOROIDAL CORE FROM MAGNETIC PARTICLES COMPRISING THE STEPS OF CONFINING A MEASURED QUANTITY OF MAGNETIC PARTICLES IN A TOROIDAL SHAPE HAVING A CENTRAL AXIS, INNER AND OUTER SIDEWALLS, ROUNDED EDGE BOTTOM CONFIGURATION, AND TOP SURFACE, THE INNER AND OUTER SIDEWALLS OF THE TOROIDAL SHAPE BEING IN CONCENTRIC RELATIONSHIP AND TAPERING SLIGHTLY TOWARD EACH OTHER IN APPROACHING THE BOTTOM CONFIGURATION WITH A CURVED ANNULAR SURFACE AT EACH SIDEWALL FORMING AT LEAST PART OF THE BOTTOM CONFIGURATION OF THE TOROIDAL SHAPE, APPLYING PRESSURE UNIFORMLY TO THE TOP SURFACE OF THE TOROIDAL SHAPE WITH THE PRESSURE BEING APPLIED IN A DIRECTION PARALLEL TO THE CENTRAL AXIS OF THE TOROIDAL SHAPE TO REDUCE THE SIZE OF THE TOROIDAL SHAPE AND FORM AN INTEGRAL MAGNETIC CORE, MAINTAINING THE INNER AND OUTER SIDEWALLS AND THE ROUNDED EDGE BOTTOM CONFIGURATION OF THE TOROIDAL SHAPE IN FIXED POSITIONAL RELATIONSHIP WHILE APPLYING THE PRESSURE TO THE MAGNETIC PARTICLES TO REDUCE THE SIZE OF THE TOROIDAL SHAPE, RELIEVING THE PRESSURE FROM THE TOP SURFACE OF THE TOROIDAL SHAPE WHILE MAINTAINING THE INNER AND OUTER SIDEWALLS AND ROUNDED EDGE CONFIGURATION IN FIXED POSITIONAL RELATIONSHIP, AND APPLYING FORCE TO THE INNER SIDEWALL OF THE TOROIDAL SHAPE AND ITS ASSOCIATED CURVED ANNULAR SHAPE AT THE BOTTOM CONFIGURATION OF THE TOROIDAL SHAPE IN A DIRECTION OPPOSITE TO THE PRESSURE APPLIED TO REDUCE THE SIZE OF THE TOROIDAL SHAPE CAUSING THE INNER SIDEWALL AND ITS ASSOCIATED ANNULAR CURVED SURFACE TO MOVE ALONG THE CENTRAL AXIS OF THE TOROIDAL SHAPE WITH RESPECT TO THE OUTER SIDEWALL AND RELEASE THE INTEGRAL MAGNETIC CORE.
