  • Patent number: 8757390
    Abstract: Since Thomas Edison invented the magnetic roller separator for concentrating nickel mineral, drum and roller type separators have become the most common magnetic separators. These devices can be constructed with permanent magnets or with electromagnets, and the drum separator can operate with a dry or wet supply. However, still today, strongly magnetic material detaching from the roller is a problem that has been tried to be resolved by introducing the magnets inside the cylinders, in only one area thereof, in such a way that when the material is rotated on the cylinder and moves away from the magnetised area, it falls as a result of gravity. This system has a highly complex structure. The invention uses novel and powerful, very small neodymium magnets to cover the entire surface of the roller. In this way, a small device with a larger yield is produced in a very simple and economic manner.

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.

  • Patent number: 8056730
    Abstract: A magnetic separator conventionally includes a conveyor belt (1) that forms a closed loop around a magnetic roller (2) and an idler roller (3) to convey a mix of materials (4), the novel aspect being that the belt (1) is not driven by the roller (2) but by the idler roller (3) that is motorized, and in that the belt (1) is not wound directly on the roller (2) but on an idle tube (3?) of non-magnetic material inside which the roller (2) is arranged with a minimum gap. It is therefore possible to obtain two surfaces with a relative slip and therefore two different speeds whereby the attracted material, during the path defined by the 180° of tangency to the magnetic area, due to the backing or advancing of the magnetic polarities tends to rotate backward or forward with respect to the travel direction of the belt.

  • Publication number: 20030196935
    Abstract: A magnetic separator system comprises a feed chute having an adjustable feed chute floor portion for controlling the release of discharge slurry from the feed chute onto a rotating magnetic drum separator. Adjusting the adjustable chute floor portion controls where discharge slurry released from the feed chute contacts the outer surface of the drum, allowing the contact point to be maintained for optimal separation simply through such adjustments. Precise control over flow of discharge slurry onto the drum notwithstanding variations in flow of discharge slurry permits the system to use an open construction, which is more compact and which reduces wear and abrasion and makes the system more accessible for repair. The field of attraction from magnets within the drum extends not only around the circumference of the drum, but also into the feed chute over the adjustable feed chute floor portion.

  • Patent number: 6608834
    Abstract: An apparatus for and method of encapsulating Ethernet frame data in Very high speed Digital Subscriber Line (VDSL) frames. The VDSL frames are transmitted over a point to point VDSL link where they are subsequently extracted and forwarded as standard Ethernet frames. The VDSL facility transport system comprises an Ethernet to VDSL Consumer Premises Equipment (CPE) coupled to a DSL Access Multiplexer (DSLAM) over a VDSL transport facility. The Ethernet to VDSL CPE functions to receive a 10BaseT Ethernet signal and encapsulate the Ethernet frame into a VDSL frame for transmission over the VDSL facility. The DSLAM is adapted to receive VDSL frames, extract Ethernet frames therefrom and output a standard Ethernet signal. Ethernet frames are encapsulated within VDSL frames and transmitted on the wire pair without regard to the state of the SOC signals thus overcoming the problems associated with syncing the transmission of the Ethernet data with the SOC signals.

  • Publication number: 20030010681
    Abstract: A method and apparatus of separating integrated circuit (IC) devices according to magnetic properties of the devices. A plurality of IC devices are subjected to a magnetic field. The IC devices containing only nonferrous material are not responsive to the magnetic field and are thus gathered to a first collection site. The IC devices containing ferrous material adhere to a moving surface proximate the magnetic field and are transported to a second collection site. The sorted devices are then transported to separate locations for further processing. The apparatus used for separating the IC devices may include a conveyor having a magnetic drum and an antistatic belt which travels about the magnetic drum. The conveyor allows nonferrous IC devices to fall off the edge of the magnetic drum into the first collection site while transporting the ferrous IC devices to another location for collection.
