Abstract
Abstract An apparatus and method for electromagnetically crushing, mixing and stirring substances is disclosed. The apparatus has a container for containing ferromagnetic or non-magnetic conductive working pieces together with substances to be processed, shifting magnetic field generators which act on and generate a random motion of the work pieces, and a mechanical driver which imparts a relative motion to said container on a plane generally parallel with the shifting direction of the shifting magnetic field generated by said shifting magnetic field generators. Similarly, the method comprises moving the container relative to shifting magnetic field generators on a plane generally parallel with the shifting directions of the generated magnetic fields.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
171 words
An apparatus for electromagnetically processing substances comprising: an elongated container having two opposed generally parallel sides for receiving working pieces responsive to a magnetic field and substances to be processed, a first shifting magnetic field generator adjacent to one side of the container producing a magnetic field which shifts in one direction within the container and a second shifting magnetic field generator adjacent to the opposite side of the container producing a magnetic field which shfits in the opposite direction within the container, the first and second shifting magnetic field generators being effective to impart a violent random motion to the working pieces due to electromagnetic force applied by said shifting magnetic field generators to thereby crush, mix and stir the substances to be processed; and a mechanical driving means for imparting a relative motion to said container between said first and second shifting magnetic field generators in a direction generally parallel to the shifting directions of said shifting magnetic fields, to thereby substantially maintain random motion of said working pieces.
Claim 2
Independent Claim
171 words
An apparatus for electromagnetically processing substances comprising: an elongated container having two opposed generally parallel sides for receiving working pieces responsive to a magnetic field and substances to be processed, a first shifting magnetic field generator adjacent to one side of the container producing a magnetic field which shifts in one direction within the container and a second shifting magnetic field generator adjacent to the opposite side of the container producing a magnetic field which shfits in the opposite direction within the container, the first and second shifting magnetic field generators being effective to impart a violent random motion to the working pieces due to electromagnetic force applied by said shifting magnetic field generators to thereby crush, mix and stir the substances to be processed; and a mechanical driving means for imparting a relative motion to said container between said first and second shifting magnetic field generators in a direction generally parallel to the shifting directions of said shifting magnetic fields, to thereby substantially maintain random motion of said working pieces.
Claim 3
Dependent Claim
86 words
An apparatus for electromagnetically processing substances as claimed in claim 1, wherein said container has a generally ring shape and is partitioned into a plurality of chambers along its peripheral direction, and wherein the first and second shifting magnetic field generators have a generally circular shaped arc portion and are positioned on opposite sides of said container, and wherein said mechanical driving means comprises means for turning said container on its axis to rotate said container adjacent said arc positions of said shifting magnetic field generators.
Claim 4
Dependent Claim
60 words
An apparatus for electromagnetically processing substances as claimed in claim 1, wherein said first and second shifting magnetic field generators are generally flat in shape, and wherein said container has a generally flat shape, and wherein said driving means comprises means for reciprocally moving said container in a direction generally parallel with the shifting directions of said shifting magnetic fields.
Claim 5
Dependent Claim
73 words
An apparatus for electromagnetically processing substances as claimed in claim 1, wherein said container has a generally flat shape, and wherein said first and second shifting mgnetic field generators are generally flat in shape and wherein said driving means comprises means for turning said container on an axis at a generally right angle to the shifting directions of said magnetic fields and in parallel with said first and second shifting magnetic field generators.
Claim 6
Independent Claim
105 words
A method of electromagnetically processing substances in a container having two opposed generally parallel sides using working pieces responsive to a magnetic field to crush, mix and stir the substances, comprising: imparting random motion to the working pieces in the container using two shifting magnetic field generators producing magnetic fields which shift in opposite directions and act on the working pieces from the opposite sides of the container; and imparting motion to said container relative to the shifting magnetic field generators in a direction generally parallel with the shifting directions of said shifting magnetic fields, to thereby substantially maintain random motion of said working pieces.
Claim 7
Independent Claim
105 words
