A system for processing scrap material that includes a variable-power electromagnetic drum separator wherein shredded scrap material is placed in free fall at a position proximate the electromagnetic drum separator. A first fraction of the scrap material is attracted to the electromagnetic drum separator and is carried under the rotational axis of the electromagnetic drum separator thereby separating the first fraction of material from a second fraction of the material which continues to free fall and wherein the first fraction is a low-copper ferrous material with the second fraction having a higher non-ferrous content than the first fraction. A magnetic drum separator may be positioned upstream of the variable-power electromagnetic drum separator and be used to separate non-ferrous materials. The variable-power electromagnetic drum separator may be adjusted so that the second fraction includes some ferrous material. A robotic picker may be used to remove undesirable materials from the second fraction.

A magnetic pole for use in a magnetic separator comprises a body having a central core and two cantilevered pole arms, each pole arm extending at a perpendicular angle relative to the central core and having a faceplate at and end thereof, wherein at least one cantilevered pole arm and corresponding faceplate thereof are adapted for selective removal and re-attachment of the faceplate with the cantilevered pole arm.

A method for performing a magnetic separation procedure that includes transporting a receptacle containing a fluid medium to a first location of a system, where the fluid medium contains both a sample material and a suspension of magnetically-responsive solid supports. At the first location, the fluid medium is exposed to a first magnetic field for a first dwell period, thereby isolating the solid supports within the receptacle, where no portion of the fluid medium is removed from the receptacle at the first location. The receptacle is then transported from the first location to a second location of the system, where the fluid medium is exposed to a second magnetic field for a second dwell period. Following the second dwell period, at least a portion of the fluid medium is removed from the receptacle. A suspension fluid is then dispensed into the receptacle, and the contents of the receptacle are agitated to suspend the solid supports within the suspension fluid.

A manufacturing method of an operation pipe, which use a gel to perform operations such as separation, extraction, purification, elution, recovery, analysis and the like of target components that are biological components such as nucleic acids. More specifically, a manufacturing method of an operation pipe, with which it is possible to perform operations such as separation, extraction, purification, elution, recovery, analysis and the like of target components in a sealable pipe by operating magnetic particles in the pipe under a magnetic field from outside of the pipe.

A heat exchange apparatus for removing magnetic particulates from a gas stream, including a rotating element basket having a regenerative heat exchanger and at least one magnetic element. A method of removing magnetic particulates from a gas stream, including heating the regenerative heat exchanger during a first portion of a cycle as a segment of the rotating element basket passes through a first zone wherein contact is made with a flue gas thereby accumulating any magnetic particulates as they are attached to the magnetic element. Then cleaning a portion of the magnetic element during a second portion of the cycle. And cooling the regenerative heat exchanger and simultaneously heating an inlet air stream during a third portion of the cycle as the segment of the rotating element basket passes through a third zone wherein fluidic contact is made with the air inlet stream.
