An electromagnetic valve for a hydraulic system for an automatic transmission of a vehicle. An armature chamber is filled with hydraulic medium and fluidically connected to hydraulic lines of the hydraulic system. An armature is mounted in the armature chamber such that its stroke is adjustable. The armature includes a shut-off body and divides the armature chamber into an opening-side chamber facing the flow opening and into an inner chamber facing away from the flow opening. During a stroke of the armature, an oil exchange occurs, and a displacement volume of the hydraulic medium overflows from the opening-side chamber into the inner chamber. A hydraulic line leading to the opening-side chamber or to the inner chamber of the armature chamber includes a dirt collecting element that is designed as a permanent magnet and that retains contaminations in the hydraulic medium that flows through the hydraulic line during an oil exchange.

The application provides an apparatus for removing ferrous particles from an oil or gas process liquid or slurry and a method of use. The apparatus has a first inner cylindrical sheath and a second outer cylindrical sheath arranged concentrically on a longitudinal axis to create an annular volume. A helical screw flight on the first or second cylindrical sheaths extends across the annular volume, and a magnet assembly extends along the longitudinal axis, such that ferrous particles are attracted to a surface of the annular volume. The apparatus has an inlet a discharge outlet, and a ferrous particle collection location. The screw flight and the cylindrical sheath operable to rotate with respect to the magnet assembly to convey particles to the collection location. The apparatus includes a retaining surface to retain collected particles.

An inclined magnetic holder is disclosed, comprising a magnetic base and a centrifuge tube support plate. The centrifuge tube support plate is provided with centrifuge tube support holes. The magnetic base comprises a first bottom plate, a fixing plate provided on the first bottom plate, and two first-side support plates respectively provided at two sides of the fixing plate. Respective top portions of the two first-side support plates are provided with a position-locating slot. A bottom surface of the position-locating slot is configured with an inclined angle. Two ends of the centrifuge tube support plate are respectively provided with a position-locating protruding block for fitting and assembling into the position-locating slot. The centrifuge tube support holes are evenly and linearly distributed on the centrifuge tube support plate. An elastic circular engagement component for holding a centrifuge tube is provided inside the centrifuge tube support holes. A block magnet is fixed to the fixing plate at a location below and corresponding to each of the centrifuge tube support holes. The block magnets below each of the centrifuge tube support holes correspond to each of the centrifuge tubes. A north pole or south pole surface of the block magnet faces the centrifuge tube and is parallel to an axis of the centrifuge tube.

The objective of the present disclosure is to provide a technique for reducing a quantity of magnetic particles remaining on a reaction vessel wall surface in a cleaning step for reducing, in a stepwise manner, an amount of a magnetic particle solution in the reaction vessel. The automated analysis device according to the present disclosure causes an agitating mechanism to operate in such a way that a magnetic substance remaining on the wall surface of the vessel in the previous cleaning step is captured by a cleaning solution in the next cleaning step (see FIG. 10).

A magnetic drum including a plurality of magnets mounted along a circumferential direction on a holder. The magnets are disposed such that magnetic pole surfaces face each other along the circumferential direction on the holder, and the magnets are engaged with the holder so as not to move in a radial direction.

In at least one illustrative embodiment, an electromagnetic filter may include a pipe and a magnetic field generator such as an array of permanent magnets. The magnetic field generator generates a magnetic field through a filter section of the pipe. Multiple filter elements are positioned within the filter section of the pipe. The filter elements include a magnetic material and a biorecognition element to bind with a microorganism. The biorecognition element may be a bacteriophage that is genetically engineered to bind with the microorganism. The magnetic field forces the filter elements to positions within the filter section of the pipe. A fluid media may be flowed from an inlet of the pipe to an outlet of the pipe, through the filter section. The fluid media may be a liquid food such as fruit juice. Other embodiments are described and claimed.

A collection kit for the removal of unwanted material from a surface, said kit comprising: iv) ferromagnetic material to absorb and/or adsorb the unwanted material when spread across the unwanted material creating an area of operation; v) an apparatus having a magnetic source operable to attract the ferromagnetic material together with absorbed and/or adsorbed unwanted material when the magnetic source is touching or in the vicinity of the area of operation; and vi) means to dislodge the ferromagnetic material and absorbed and/or adsorbed unwanted material from the apparatus once the ferromagnetic material has been removed from the area of operation.

There is provided a magnet apparatus for generating a high gradient and/or high strength magnetic field. The magnet apparatus comprises: a first plurality of magnets (110) disposed in a first layer (101) and generating a first magnetic field. Each magnet (110) of the first plurality is adjacent at least one other magnet (110) of the first plurality, and each magnet of the first plurality has a magnetic field polarity (120) that is rotated with respect to that of the adjacent magnet (110) of the first plurality. The magnet apparatus also comprises a second plurality of magnets (140) disposed in a second layer (102) and generating a second magnetic field. Each magnet (140) of the second plurality is adjacent a magnet (110) of the first plurality, and each magnet (140) of the second plurality has a magnetic field polarity (120) that is rotated with respect to that of the closest magnet (140) of the second plurality. The second magnetic field combines with the first magnetic field to create a magnetic field peak having a larger gradient than that of the first magnetic field. There is also provided a method of separating particles using the magnet device.

Disclosed herein is an improved method for magnetic capture of target molecules (e.g., microbes) in a fluid. Kits and solid substrates for carrying the method described herein are also provided. In some embodiments, the methods, kits, and solid substrates described herein are optimized for separation and/or detection of microbes and microbe-associated molecular pattern (MAMP) (including, e.g., but not limited to, a cell component of microbes, lipopolysaccharides (LPS), and/or endotoxin).

A ferro-magnetic material recovery system includes a drum rotating within a magnet housing. An array of magnets mounted within the magnet housing have corresponding magnetic fields which decrease in strength in the direction of rotation of the drum to extract the material from a slurry flowing through the drum. Flow deflectors may be mounted in the drum. The array of magnets may form a magnetic core having magnetic fields that are radially aligned.
