  • Patent number: 8795523
    Abstract: An embodiment of the invention relates to a device for detecting an analyte in a sample. The device comprises a fluidic network and an integrated circuitry component. The fluidic network comprises a sample zone, a cleaning zone and a detection zone. The fluidic network contains a magnetic particle and/or a signal particle. A sample containing an analyte is introduced, and the analyte interacts with the magnetic particle and/or the signal particle through affinity agents. A microcoil array or a mechanically movable permanent magnet is functionally coupled to the fluidic network, which are activatable to generate a magnetic field within a portion of the fluidic network, and move the magnetic particle from the sample zone to the detection zone. A detection element is present which detects optical or electrical signals from the signal particle, thus indicating the presence of the analyte.

    Abstract: A power steering fluid filter includes a housing that defines an interior chamber, an inlet port communicating with the upstream end of the interior chamber, and an outlet port communicating with the downstream end of the interior chamber. A movable thimble filter is disposed within the housing and an annular magnet is located at the mouth of the thimble filter. A spring biases the thimble filter and magnet toward the inlet port of the housing. In use, power steering fluid passes through the housing and debris is captured by the thimble filter. Ferrous particles entrained in the fluid flow are attracted to and captured by the magnet. When the thimble filter becomes clogged, it is displaced by the pressure of the fluid against the clogged filter so that fluid can flow around and bypass the thimble filter while still being exposed to the magnet for removing ferrous particles.

  • Patent number: 8636907
    Abstract: A two-stage sealed magnetic filter continuously removes magnetic and non-magnetic contaminants from liquid process streams. Elongated non-magnetic holder sleeves encasing magnet bars attract magnetic contaminants while a screen cylinder captures non-magnetic contaminants. The magnet bars are accessible without having to open the interior of the housing to the environment. Thus, during maintenance, removing the magnet bars from the holder sleeves releases the magnetic contaminants that have adhered to the holder sleeves into the screen cylinder which partially encloses the holder sleeves. Contaminants are flushed out of the magnetic filter without exposing workers to potentially hazardous substances. Polymeric sludge occluded with iron compounds can be effectively removed from streams in refineries and chemical plants. The iron compounds are formed from carbon steel which is prevalent in plant machinery and that corrodes in the presence of acidic contaminants.

  • Publication number: 20130240455
    Abstract: A magnetic filter employs a magnetic core assembly that incorporates a plurality of exchangeable holder sleeves, each enclosing permanent magnets. Neither the sleeves nor magnetic bars are mechanically fixed to the filter housing. The magnet bars and holder sleeves are individually accessible. The number of holder sleeves in the magnetic core assembly is flexible. The magnetic filter in equipped with a screen that partially encloses the elongated holder sleeves to treat streams that contain degradation sludge, iron containing particles or flakes, and non-magnetic polymeric materials. In operation, a feed stream initially contacts the magnetic core assembly where paramagnetic contaminants become deposited onto the exterior surface of the holder sleeves under direct influence of strong magnetic field generated by the magnet bars. The mesh screen cylinder subsequently captures non-magnetic and weakly magnetic contaminants of a certain size before the cleaned stream exits the magnetic filter.

  • Publication number: 20130240456
    Abstract: Devices and methods for label-free separation of material. A fluid-filled settling chamber is used for settling material by gravity. A fluid mixture comprising a target material and at least one non-target material is introduced into the settling chamber, where the target material has a paramagnetic property. A magnetic field is applied to the settling chamber sufficient to impede gravitational settling of the target material and not affect gravitational settling of the non-target material, in order to separate the target material from the non-target material.

  • Patent number: 8512559
    Abstract: Embodiments of the invention relate to device, method, and system for separation and/or detection of biological cells and biomolecules using micro-channels, magnetic interactions, and magnetic tunnel junctions. The micro-channels can be integrated into a microfluidic device that may be part of an integrated circuit. Magnetic interactions used for the separation are created, in part, by magnetic stripes associated with the micro-channels. Detection of biological cells and biomolecules is effectuated by a magnetic tunnel junction sensor that comprises two ferromagnetic layers separated by a thin insulating layer. The magnetic tunnel junction sensor can be integrated into a silicon based device, such a microfluidic device, an integrated circuit, or a microarray to achieve rapid and specific separation and/or detection of biomolecules and cells.

  • Patent number: 8512570
    Abstract: A wastewater treatment method in an embodiment includes: mixing primary aggregates made of magnetic substances and a dispersion medium to make a suspension; and passing the suspension through a filter to allow the primary aggregates to remain on the filter and to form a secondary aggregate made of an aggregate of the primary aggregates. Further, the wastewater treatment method in the embodiment includes; passing wastewater through the secondary aggregate to remove suspended solids and oil in the wastewater; dispersing the secondary aggregate in a dispersion medium to decompose the secondary aggregate into the primary aggregates and to wash the primary aggregates; and collecting the primary aggregates with magnetic separation.

  • Patent number: 8506820
    Abstract: A continuous online process for rejuvenating whole stream of contaminated lean sulfolane in an extraction system is provided. A rejuvenator is installed in the solvent circulation loop to remove the contaminants continuously to keep the solvent clean, effective and less corrosive. The rejuvenator includes a high pressure vessel with a removable cover and a round rack with vertical stainless steel tubes fitted in the high pressure vessel. A magnetic bar is placed in each stainless steel tube. A screen cylinder is installed outside the ring of stainless steel tubes. As the contaminated sulfolane is passed through the rejuvenator, the rejuvenator picks up contaminants. The rejuvenator can be dissembled to remove the contaminants periodically. The rejuvenator is simple in construction, reliable in operation, and low in operation and maintenance costs. With this rejuvenator, the extraction system operates at high efficiency and high capacity without the dreaded corrosion.
