Eddy Current Separator
US Patent:
5080234, Jan 14, 1992
Filed:
Aug 15, 1990
Appl. No.:
7/568271
Inventors:
William H. Benson - Erie PA
Assignee:
Walker Magnetics Group, Inc. - Worcester MA
International Classification:
B03C 124
US Classification:
209212
Abstract:
The eddy current separator apparatus disclosed herein employs first and second cylinders, each of which is provided with means for generating a circumferential series of radially directed magnetic poles of alternating polarity. The cylinders are mounted for rotation around parallel axes with an essentially vertical gap between them. A mixture of electrically conductive and non-conductive particles can be fed into the gap from one side. The cylinders are rotated synchronously in opposite directions with poles of opposite polarity facing across the gap, at a speed substantially higher than the speed of mixture feed. Electrically conductive non-magnetic particles are impelled by eddy currents generated by the magnetic flux projected across the gap by the faacing moving poles and can be received or collected separately from free falling non-conductive particles.
Folded Springs For Vibratory Feeders And Conveyors
US Patent:
4121708, Oct 24, 1978
Filed:
May 20, 1977
Appl. No.:
5/798752
Inventors:
William H. Benson - Erie PA
Thomas H. Falconer - Erie PA
Thomas H. Falconer - Erie PA
International Classification:
B65G 2700
US Classification:
198766
Abstract:
The specification discloses a spring for powering a vibratory feeder or conveyor made up of a first leaf spring and a second leaf spring in closely spaced relation to each other. The ends of each of the two leaf springs are rigidly clamped to corresponding ends of one another and a spacer is rigidly clamped between the springs at said ends. The center of one spring leaf is fixed to the conveyor, while the center of the other spring leaf is fixed to a vibratory motor.
Resin-Empotted Dry-Type Electromagnet For Dusty And Gassey Locations
US Patent:
4009459, Feb 22, 1977
Filed:
May 5, 1975
Appl. No.:
5/574803
Inventors:
William H. Benson - Erie PA
Gerald D. Rose - Erie PA
Gerald D. Rose - Erie PA
International Classification:
H01F 500, H01F 2708
US Classification:
335300
Abstract:
An electromagnet is disclosed. The electromagnet has a winding that is wet wound with an epoxy material filled with grains of a material having a high coefficient of thermal-conductivity. The entire winding is empotted dry in a similar epoxy having grains of the said material. Fins are connected to the outside of the dry empotment for carrying away heat transferred to the fins from the coil.
Electromagnetic Vibratory Feeder
US Patent:
4880106, Nov 14, 1989
Filed:
May 19, 1988
Appl. No.:
7/195862
Inventors:
Thomas H. Falconer - Erie PA
William H. Benson - Erie PA
William H. Benson - Erie PA
Assignee:
Eriez Manufacturing Company - Erie PA
International Classification:
B65G 2708
US Classification:
198763
Abstract:
A vibratory feeder having a tray with a conveying surface and springs. The springs are each made up of flat plate like first leaves and flat plate like second leaves rigidly attached together. One part of each spring is connected to the tray and the other part is connected to the base. The longitudinal axis of the leaves extend perpendicular to the longitudinal axis of the tray. The springs are spaced from each other whereby the tray is vibrated in an arcuate path relative to the base to vibrate the tray for moving material on the tray.
