| 20090159511 | ELECTROMAGNETIC SEPARATOR AND SEPARATION METHOD OF FERROMAGNETIC MATERIALS - Electromagnetic separator comprising two or more solenoids ( | 06-25-2009 |
| 20090314693 | SELF-PROPELLED CRUSHING MACHINE - A self-propelled crushing machine is provided which ensures that, even when crushed pieces of an object include a concrete reinforcing steel bar or other like material piece, it is prevented that the concrete reinforcing steel bar will pierce into a conveyor belt. To this end, the crushing machine has a memory for storing a relationship in belt velocity between a conveyor belt and a magnetic separator belt which relationship allows a concrete reinforcing steel bar attracted and adhered to the magnetic separator belt to be taken off from the conveyor belt before the trailing end of the concrete reinforcing steel bar travels past a leading end attraction/adhesion position at which the leading end of the concrete reinforcing steel bar is to be attracted and adhered to the magnetic separator belt. In addition, the crushing machine also includes a controller configured to provide respective control currents to a conveyor belt drive means and a magnetic separator belt drive means, based on the belt velocity relationship stored in the memory. | 12-24-2009 |

| 20110147279 | Eddy Current Separator - An eddy current separator (“ECS”) separates electroconductive and non-electroconductive materials. The materials can include “fines” having diameters less than about 10 millimeters. The ECS includes first and second hubs coupled to opposite ends of a magnet support tube. Magnets are coupled to the magnet support tube, substantially between the hubs. A motor coupled to one or both of the hubs rotates the magnet support tube and magnets to generate an eddy current in electroconductive material conveyed proximate the separator. The material in which the eddy current is created is repelled and projected away from the ECS along a predictable trajectory. An eddy current is not generated in nonconductive material conveyed proximate the separator. Therefore, that material is not projected away. A jacket tube may house the magnets and contain centrifugal forces of the magnets during rotation thereof. That tube may comprise a Ti60 titanium alloy or other material. | 06-23-2011 |
| 20150101965 | MAGNETIC SEPARATOR - A weak magnetic force magnetic separator, including: a belt conveyor conveying separation target particles; and a suspended magnet unit provided at a distance above the belt conveyor and configured to magnetically attract, with a uniform, weak magnetic force, the separation target particles conveyed over a belt. With a length of the magnet unit in its longer direction being greater than a belt width of the belt, and with the magnet unit placed such that its longer direction is aligned with the belt width direction and its both ends overhang the belt width, and such that a distance from the surface of the belt is constant across its longer direction, magnetic flux density variations in the belt width direction over the belt surface facing the magnet unit are 10% or less within a weak magnetic force range of from over 0 to 700 gauss. | 04-16-2015 |
| 20150122708 | PIN SORTER - A system for sorting merchandise tags. The system includes a housing configured to receive a first portion of the merchandise tag and a second portion of the merchandise tag, the first portion and the second portion configured to attach to one another. The system also includes a separator configured to separate the first portion and the second portion based on one or more physical characteristics of the first portion and the second portion. The system further includes a rotating mechanism, where the rotating mechanism allows the user to control the separator. The system additionally includes a container for receiving the smaller portion which falls through the separator. | 05-07-2015 |
