  • Patent number: 9044719
    Abstract: An apparatus and method for mixing a liquid having particulate includes a vessel for containing the liquid and an axial impeller rotating about a substantially vertical axis. The impeller is adapted for submerging below the liquid surface by a distance approximately one-quarter to one-half of the height of the liquid. The impeller is oriented upwardly to produce (a) an inner, upward flow region located along the vertical axis of the vessel, (b) a transition flow region above the impeller in which liquid moves radially outwardly toward the vessel sidewall, and (c) an outer, downward flow region located along the sidewall. The impeller spins at a variable speed, such that the flow is capable of entraining solid particles having a settling velocity of up to approximately 1 foot per minute in the liquid, and the speed of the impeller is chosen to enable particles having a desired settling velocity to settle to the vessel bottom.

  • Patent number: 6722778
    Abstract: A method and an apparatus for extruding material, the material being extruded with an apparatus comprising at least one rotatable rotor and at least one stator, the rotor and the stator comprising grooves, whereby the grooves make the material move through the apparatus when the rotor is rotated. The rotor and stator surfaces facing each other have a wavelike cross-section, and the grooves are so arranged that at the ridge of a wave the depth of a groove reaches its maximum, and at the bottom of a wave the depth reaches its minimum. The bottom of the wave in the rotor is at the ridge of the wave in the stator and vice versa. This makes the material move alternately from a rotor groove to a stator groove, and back.

  • Publication number: 20040052156
    Abstract: A dynamic mixer in which two elements are rotatable relative to each other about a predetermined axis and between which is defined a flow path extending between an inlet for materials to be mixed and an outlet. The flow path is defined between surfaces of the elements each of which surfaces defines a series of annular projections (8, 12) centred on the predetermined axis (10). The surfaces are positioned such that projections defined by one element extend into spaces between projections (12) defined by the other element. At least one cavity is formed in each projection (8, 12) to define a flow passage bridging the projection in which the cavity is formed. Each of the elements may be generally conical althrough each of the elements could be generally cylindrical or planar, providing projections in the two elements overlap.

  • Patent number: 6641993
    Abstract: Apparatus and a method for mixing a liquid within a disposable aspirating probe tip so that most of the liquid is forced to move past a transition zone between two different inside diameters to cause rotational mixing. The apparatus and method can be used to provide agglutination of blood, which in turn can be used for blood typing. The probe tip can comprise a single integral piece, or two separate portions. The transition zone can comprise a sharp demarcation between inside diameters, or a smooth one.

  • Publication number: 20030072212
    Abstract: A diffuser provides the ability to diffuse one or more infusion materials into a host material. A rotor and stator rotate relative to one another. The infusion materials are drawn through openings in the rotor and stator. These openings are also causing turbulence within the host material, which is flowing through an area between the rotor and stator. As aligned openings pass one another, succussion occurs, which provides energy to diffuse the infusion materials into the host material to an extremely high degree. The opening patterns in the rotor and stator can be designed to operate at a single frequency or at multiple frequencies. The frequencies of operation may affect bonding between the infusion materials and the host material and may also be effective in break down of complex molecular structures.

  • Patent number: 6547850
    Abstract: A method for mixing particles in a liquid or semi-liquid medium, such as ceramic reinforcing particles in a molten metal or metal alloy matrix for the production of stir-cast metal matrix composite (MMC) materials. The particles can be introduced under the surface of the matrix by feeding the particles through the inner passage of a rotatable hollow impeller tube. The impeller tube is terminated at its lower end by an impeller head that includes teeth positioned proximate to an impeller base. The particles enter the matrix through a shear region in and around the volume between the impeller base and the impeller head. The rotating impeller and the high shear force thereby created wet the particles in the composite matrix and effect homogenization of the composite matrix. The present invention may be practiced either under vacuum or atmospheric pressure.

  • Patent number: 6412714
    Abstract: An apparatus for mixing, grinding, dispersing or emulsifying including a rotatable drive, a rotor body connected for rotation with the drive and having at least one aperture for fluid flow through the rotor body and a flow divider plate structure extending within the rotor body for preventing conglomeration of particulates contained within the fluid in the rotor body. Preferably, a stator body is secured outside of the rotor body and each of the rotor and stator bodies include respective apertures for allowing fluid flow therethrough. The flow divider plate structure prevents the usual swirling action of liquid and solid particulates within the rotor body such that the mixture has a more desirable flow pattern and so that particulates do not conglomerate to form a mass that clogs the rotor body. Further aspects and embodiments of the invention provide advantageous seal structure and structure for increasing productivity.

The surface of each distributor cone comprises guiding surfaces extending with differing steepness from a bottom sided base situated within one wedge area to a tip positioned at least close to the wall. Each distributor cone is inclined obliquely towards one of the vertical augers the sense of rotation of which is directed towards this distributor cone.

    Abstract: A diffuser for incorporating one or more infusion materials into a host material. The diffuser includes a rotor 12 and stator 30 rotating relative to one another. The infusion materials are drawn through openings in the rotor and stator. During movement of the rotor, the openings cause cavitation of the host material in the channel 32 resulting in diffusion of the infusion materials through the openings and into the host material. The opening patterns in the rotor and stator can be designed to operate at a single frequency or a multiple frequencies. The frequencies of operation may affect bonding between the infusion materials and the host material and may also be effective in breakdown of complex molecular structures.
