Patent number: 6817474Abstract: A magnetic metal removing device for color sorting apparatus includes a hollow feeding roll. Within a hollow portion of the feeding roll, a magnet is arranged such that it closely opposes to a part of an inner surface of the hollow feeding roll to form a magnetic force active surface on the corresponding outer surface of the feeding roll. Magnetic metal mixed in raw granular objects is attracted on the magnetic force active surface. The magnetic forced active surface changes to a magnetic force inactive surface as the feeding roll rotates. The magnetic metal caught on the feeding roll is released from the magnetic forced inactive surface and colleted by a collecting device.Type: GrantFiled: December 3, 2002Date of Patent: November 16, 2004Assignee: Satake CorporationInventors: Norimasa Ikeda, Hiroshi Tanimoto

Patent number: 6659283Abstract: The present invention is directed to a method of purifying capacitor grade powders. The capacitor grade powder is initially placed into a purifying machine that disperses at least one contaminate into the capacitor grade powder. The powder is then placed into a magnetic separation device that separates at least one contaminate from the capacitor grade powder. The capacitor grade powder is then processed into an electrical energy storage device, wherein the capacitor grade powder has minimal contaminates therein.Type: GrantFiled: May 17, 2001Date of Patent: December 9, 2003Assignee: Wilson Greatbatch Ltd.Inventors: Barry C.

Patent number: 6386374Abstract: A multi-mass filter for separating particles of a multi-species plasma includes a chamber, which defines an axis. A radial electric field is crossed with a magnetic field (E×B) to move the particles of different mass (M1, M2 and M3) on respective trajectories into respective first, second and third regions. Specifically, particles M1 are confined in the first region, while both particles M3 and M2 are ejected from the first region into the second region and only the particles M3 are ejected from the second region into the third region.Type: GrantFiled: May 17, 2001Date of Patent: May 14, 2002Assignee: Archimedes Technology Group, Inc.Inventors: Robert L.

Patent number: 6293406Abstract: A multi-mass filter for separating particles according to their mass-charge ratio includes a chamber for receiving a multi-species plasma that includes particles therein having different mass-charge ratios (with M1<M2<M3). Inside the chamber, which defines an axis, a radial electric field is crossed with a magnetic field (E≦B) to move the particles (M1, M2 and M3) on respective trajectories into respective first, second and third regions. For one embodiment, the filter is configured so that az2Bz is held constant in the expression for cut-off mass, Mcz=eaz2Bz2/(8Vctr). For this embodiment, only the heavier particles M3 are ejected into the third region (M3>Mc3) and only the intermediate particles M2 are ejected into the second region (M2>Mc2). In another embodiment, the radial electrical field is increased outwardly from the axis to a radial distance a2 (r2) at a first rate.Type: GrantFiled: August 21, 2000Date of Patent: September 25, 2001Assignee: Archimedes Technology Group, Inc.Inventors: Robert L.
