Device for capturing and removing magnetic material from a flow of material, wherein the device includes magnet assemblies including magnet rods for capturing magnetic material in a flow of material passing the magnet assemblies and where the magnet assemblies are removably arranged to a frame assembly of the device, wherein each magnet assembly includes a set of at least two magnet rods.

Disclosed is an apparatus for removing air and particles, such as dirt, from a fluid which includes, inter alia, an elongated pressure vessel that has a vessel wall that defines an interior chamber and a vertical axis for the apparatus. Inlet and outlet ports are formed in the vessel wall, the inlet port allowing fluid to enter the interior chamber and the outlet port allowing conditioned fluid to exit the interior chamber of the pressure vessel. A plurality of concentrically arranged cylindrical mesh screen elements are positioned within the interior chamber that release entrained air from the fluid entering the interior chamber. Additionally, a cylindrical tube is positioned within the concentrically arranged mesh screen elements for removing particles from the fluid entering the interior chamber. In certain embodiments the apparatus includes a magnetic particle collector.

A magnetic rod guide for a filter comprises a base for attachment to part of a filter, a through aperture through which a magnetic rod can move, and resilient engagement means including at least one resilient latch for holding the magnetic rod in one or more fixed positions relative to the guide, the or each resilient latch further being adapted to allow movement of a magnetic rod through the through aperture in either direction, for insertion into the filter or withdrawal from the filter into one of the fixed positions.

A pipeline strainer having a body with a straining element therein. One or more magnets are removably inserted into the straining element and configured to be removed from the body without causing liquid within the cavity to drain from the pipeline strainer. A drywell is used to house the magnets. The movement of withdrawing the magnets pulls metal particles along the outer surface of the drywell toward a debris drain. A baffle is disposed at the end of the drywell that is adjacent or near the debris drain to reduce turbulence from the fluid flow within the pipeline strainer.

A rotatable magnet cradle assembly that can be used to separate swarf from a flow of fluid is provided. The cradle of magnets can be rotated a certain amount about a rotational axis from an operational position to a cleaning position. The magnet cradle may include a tube extending between two brackets, a shaft to which the two brackets are attached, and a magnet bar extending through the tube. In the operational position, the magnet provides a magnetic field that attracts swarf to an outer surface of the tube. Once it is desired to clean the assembly, the shaft is rotated to move the two brackets and tube out of the fluid flow and to a position proximate a discharge location, where the magnet bar can be removed from the tube to release the swarf.

The present invention relates to novel modules for transferring magnetic beads, an automated system comprising the same and a method for extracting nucleic acids using the same. The specifically designed magnet module and cover module of the present invention can be employed in the automated liquid handling apparatus by means of pre-existing moving modules (e.g., pipettor module) of the apparatus. The present invention enables a bead transfer-type method for extracting nucleic acids to be performed in an automated manner on the automated liquid handling apparatus. The present invention provides advantages of higher level of automation, more reduced cost and no need for another separate liquid handling apparatus compared to the conventional bead transfer-type method usually performed in the small apparatus designed to be used only for this bead transfer-type method. Also, the present method has the merits of more shortened reaction time compared to the conventional liquid transfer-type method.

An epicyclic geartrain includes a debris collection arrangement. The epicyclic geartrain comprises a sun gear, a plurality of planet gears, with the plurality of planet gears being supported by a planet torque ring, and a ring gear. The planet gears meshingly surround the sun gear, and the ring gear meshingly surrounds the planet gears. At least one of the sun gear, the plurality of planet gears, and the ring gear, is provided with a plurality of permanent magnet portions, and a debris collection element. The plurality of magnet portions is arranged as a circumferential array across a side of the corresponding gear. The debris collection element extends along the side face of the gear. The debris collection element is slidably positioned against the side face, such that rotation of the gear causes the debris collection element to remove any ferromagnetic debris particles that are magnetically attached to the side face.

A magnetic isolating apparatus (10) for isolating magnetic particles (66) from a suspension has an immersion section (30) which is designed to be temporarily immersed in the suspension, a guide apparatus (16) which extends along a guide path (F), a magnet arrangement (18) which is guided by the guide apparatus (16) such that it can be moved between an active position which is situated close to the immersion section (30) and an inactive position which is positioned further away from the immersion section (30) along the guide path (F), so that a magnetic field in the region of the immersion section (30) can be changed by moving the magnet arrangement (18) between the active position and the inactive position, and a drive apparatus (22, 50) by which the magnet arrangement (18) can be driven to move at least in a direction between the active position and the inactive position, wherein the drive apparatus (22, 50) is coupled in a non-physical manner to the magnet arrangement (18) by a force field and/or a fluid so as to transmit drive force.

An automatic cell isolation and collection system for sorting out target cells from a sample includes a crush module, a centrifuge module, a transport module, and a control unit. The centrifuge module includes centrifuge tubes and a magnetic mechanism providing a magnetically attractive force to at least one of the centrifuge tubes. The control unit electrically communicates with the crush module, the centrifuge module, and the transport module, and controls operation of the crush module, transport of the sample via the transport module after the sample is crushed by the crush module, centrifugation of the centrifuge module, and operation of the magnetic mechanism for providing the magnetically attractive force.

The invention provides an apparatus for removing ferrous particles from metal contaminated oil and gas process liquids or slurries and method of use. The magnetic separator apparatus comprises a vessel with an inlet and an outlet configured to allow the flow through of a liquid or slurry, or to hold a liquid or slurry inside. A plurality of magnetic rod devices is mounted upon at least one frame member secured to the vessel such that they extend into the interior of the vessel. Each magnetic rod device has a first condition in which it is operable to attract ferrous particles, and a second condition in which it is operable to dispose of ferrous particles. Embodiments of the invention provide a magnetic separator apparatus for removing ferrous particles from contaminated liquids and slurries which are stored in a storage facility.
