    Abstract: A power steering fluid filter has 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. The housing is for spicing inline with a power steering fluid hose via its inlet and outlet ports. A 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: 8025801
    Abstract: Simultaneous source-sink flow, or radial counterflow, is driven by a centrifugal pump disposed within a casing. Radially outward source flow of brine goes into a shrouding tank and concentrates while a radially inward sink flow of fresh water flows back over the pump to axial extraction. An axial pump drives sink flow and axial extraction. Convergent sink flow passes under an inductor to an axial exhaust port. Induced viscosity and inductive repulsion hinder the passage of brine in sink flow, so only fresh water can reach the axial exhaust port. Crystallization of scale-forming salts is aided by Joule heating from the inductor. Solvent and gases are continuously axially extracted in sink flow, favoring crystallization. Sodium chloride is cooled and crystallized in the shrouding tank. Brine comprising other salts flows out of the tank to treatment by suitable means. Thus brine is separated into fresh water, crystallized salt, and concentrated brine.

    Abstract: The present invention discloses a method and apparatus for separating particles and dissolved matter from a produced water fluid stream. Specifically, the present invention includes a first pressure source which transports untreated produced water or contaminated aqueous fluid into a separator annulus with a filter element disposed therein. The untreated fluid is placed under appropriate pressure sufficient to produce turbulent flow, increased particle kinetics and/or cavitation allowing the desired fluid to penetrate and pass into and through the, filter media. The treated fluid is then transported to a collection tank. The contaminant matter retained by the filter media may be removed by the nearly instantaneous reverse pressurization of the separator annulus by a second pressure source thereby removing the contaminant particles away from contact with the filter media, and which may then be transported to a waste collection tank or separator for further treatment.

The invention also contains inlet hardware allowing the mixed mineral suspension to enter the first separation chamber, and hardware allowing the three outlet (separated) streams to exit the device. One of the three outlet streams carries the minerals that have a density greater than the user selectable density set point, while the second carries the minerals that have a density less than the density set point, and the third carries clean drilling fluid.

  • Patent number: 7867388
    Abstract: A contaminated fluid recovery apparatus includes a sludge removal mechanism having a dirty tank, a conveyor, and a magnetic drum which is arranged in the fluid circulating section. The contaminated fluid recovery apparatus is provided with an overflow tank. The overflow tank has a function to keep a fluid surface of the dirty tank in a position higher than the fluid circulating section and the magnetic drum. The magnetic drum is located horizontally between a lower portion and an upper portion of the conveyor. The conveyor scrapes out chips deposited on a bottom portion of the dirty tank toward an exit section. A scraping member, which is in contact with the magnetic drum, drops sludge attracted to the magnetic drum toward the lower portion of the conveyor.

  • Patent number: 7862780
    Abstract: The present invention provides an apparatus and method of producing transformed water without contact between the original transformed water and the water to be transformed. This is accomplished by organizing the original transformed water into a geometric contained arrangement such that a central cavity is created that substantially surrounds the water that is to be transformed. The water to be transformed is placed into a confined vessel such as a cylindrical container or a pipe inside the central cavity for about sixty seconds. This water then becomes transformed in the same likeness of the molecular clustering of the original transformed water.

  • Patent number: 7796001
    Abstract: In forming magnetic blocks, a first permanent magnet may be lowered to the bottom of an upwardly open vessel, the vessel may be already filled or may be then filled with liquid and, while forcefully maintaining the first permanent magnet in that position, further permanent magnets are gradually inserted into the vessel in a direction perpendicular to their resulting joint contact surfaces, where the adjacent surfaces of the superimposed permanent magnets have an opposite polarity, while during insertion of a further permanent magnet, the liquid is drained from the space in the vessel under that inserted magnet, whereby the motion speed of the inserted magnet is controlled as it bears down on the permanent magnet lying beneath it.

  • Publication number: 20100228056
    Abstract: The present invention relates to a magnetic separation apparatus for continuous separating and recovering magnetic solid particles from a solid-liquid mixture. The apparatus includes at least one magnetic separation unit and each unit includes: an outer cylindrical vessel having a material inlet, a first outlet, and a second outlet; an inner cylindrical vessel, at least part of which extends along the axis inside the first cylindrical vessel without contacting with the inner surface of the outer cylindrical vessel; and a magnet, rendering the bottom of the inner cylindrical vessel magnetism during the first period and making the part of the surface lose its magnetism during a second period. When the solid-liquid mixture flows through the magnetic surface of the inner cylindrical vessel in the passage, the magnetic solids are absorbed and separated from the mixture.
