Patent number: 8757390Abstract: 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.Type: GrantFiled: September 6, 2010Date of Patent: June 24, 2014Assignee: Superazufre S.A.Inventor: David Alejandro Masferrer Salas

Publication number: 20030196935Abstract: 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.Type: ApplicationFiled: April 19, 2002Publication date: October 23, 2003Inventors: David Roger Miles, Peter T. Watson, A. Bruce Paige

Patent number: 6608834Abstract: 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.Type: GrantFiled: May 26, 1999Date of Patent: August 19, 2003Assignee: 3 Com CorporationInventors: Amit Lewin, Opher Yaron, Alon Hurwitz, Yuri Poddobny

Publication number: 20030010681Abstract: 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.Type: ApplicationFiled: July 12, 2001Publication date: January 16, 2003Inventors: Keith E.
