  • Patent number: 9199209
    Abstract: A mixing assembly includes an inlet, an outlet and a mixing chamber, the inlet is fluidly connected to the outlet through a plurality of micro fluid flow paths in a direction perpendicular from the inlet. The micro fluid flow paths fluidly connect to the perpendicular inlet via a curved transition portion. The curved transition portion provides a more efficient flow path for the fluid to travel from the inlet to the micro fluid flow paths to the mixing chamber. By transitioning the direction change, flow resistance is decreased, and the fluid flow rate and shear rate is increased. Increased fluid flow rate and shear rate helps to increase consistency and quality of mixing, and to reduce particle size of the fluid in the mixing chamber.

    Abstract: The present invention provides a system for enriching a flowing liquid with a dissolved gas inside a conduit. The system comprises two or more capillaries, each capillary delivering a stream of a gas-enriched liquid to the flowing liquid. The first ends of the capillaries are positioned to form an intersecting angle with respect to the effluent streams such that these streams of gas-enriched liquid collide with each other upon exit from the first ends of the capillaries, effecting localized convective mixing within the larger liquid conduit before these gas-enriched streams are able to come into close contact with the boundary surfaces of the conduit, whereby the gas-enriched liquid mixes with the flowing liquid to form a gas-enriched flowing liquid. In the preferred embodiment, no observable bubbles are formed in the gas-enriched flowing liquid. Methods of making and using such system are also provided.

    Abstract: A system and a method of providing PUR/PIR foam using flammable blowing agent. The flammable blowing agent is introduced to PUR/PIR manufacturing equipment via an independent feed-line. This enables a flammable blowing agent storage vessel to be located off site from the foam manufacturing equipment. The independent flammable blowing agent feed-line couples the off-site flammable blowing agent storage vessel with the foam production system. The preferred flammable blowing agent is pentane.

  • Patent number: 7686604
    Abstract: A screw for injection molding provides a coaxial piston that allows the effective cross-sectional area of the screw to be varied during the injection cycle permitting small shot metering with relatively large diameter injection molding screws. The screw is positioned within the injector barrel of a injection molding assembly and includes a number of threads disposed around its outer surface configured to advance molten plastic to the front of the barrel. The screw further includes a central bore having a piston slidably received within the central bore. The plastic shot to be forced out through the nozzle of the injection molding assembly is controlled by movement of the piston within the screw.

  • Publication number: 20090123385
    Abstract: A method of making a suspension of particles in a first fluid of a size suitable for responding to ultrasound, by forcing a second fluid (2) through an array of pores (30) into the first fluid (1), the pores being of substantially uniform diameter, and the pressure of the second fluid and a flow rate of the first fluid across the pores being arranged so that shear forces at the pores cause the second fluid to be suspended as substantially monodisperse particles in the first fluid. This can enable a more monodisperse suspension. The array of pores can be an etched silicon array. The suspension can be used as a contrast agent, or can be an emulsion to make droplets of a precursor material, which can be formed into capsules with a core and a shell. A liquid core can be converted to a gas to provide hollow shells.

  • Publication number: 20090052275
    Abstract: The invention concerns an arrangement to counteract problems associated with mixing in steam into a pipe that is transferring a flow of pulp of medium consistency. The arrangement comprises a chamber (101) with a cross-sectional area (A3), and a pre-determined length (x). The chamber (101) is in connection, upstream to the flow of pulp, with a first throttle section (107) that has a cross-sectional area (A1). The addition of steam through supply means (105) takes place in the first throttle section (107). The chamber (101) is in connection, downstream to the flow of pulp, with a second throttle section (122) that has a cross-sectional area (A2). The cross-sectional area (A3) of the chamber is greater than the cross-sectional area (A1) of the first throttle section and the cross-sectional area (A2) of the second throttle section.

  • Publication number: 20080159065
    Abstract: A hole-jetting type mixer-reactor, comprises the following parts: a first feeding port, a second feeding port, an outer casing, an inner casing, jet holes and a mixing reaction zone. The inner casing is inside the outer casing, and the lower portion of the outer casing forms a buffer chamber with the inner casing. The first feeding port connects with the inner casing to constitute one flow channel, and the second feeding port connects with the buffer chamber to form the other flow channel. The jet holes are on the wall of the inner casing situated at lower portion of the buffer chamber. The mixing reaction zone is inside the inner casing below the jet holes. The cross section of the inner casing is rectangular or rectangle-like. The mixer-reactor can achieve a fast mixing of two reactant streams which reacts with instantaneous, complicated parallel or consecutive competing reactions. The time scale of the mixing process is several milliseconds.

  • Publication number: 20080144430
    Abstract: The disclosure is directed to a high pressure fluid processing device for mixing, reacting, or otherwise combining fluids. The fluid processing device includes opposing, annular flow channels of different annular path areas. A first fluid enters the fluid processing device and flows through the first annular flow channel while the second fluid enters the fluid processing device and flows through the second annular flow channel. The opposing flows of fluids collide with one another within the flow channels, and exit through an outlet. The different annular path areas of the two annular flow channels may allow the two fluids to have different densities, viscosities, or both.

  • Patent number: 7281841
    Abstract: The invention relates to a mechanical device with no moving parts that homogeneously mixes two or more liquids or liquids and gases. It is possible with the device to totally saturate liquids with gas droplets of less than one micron. The device comprises an inlet for partially mixed components leading to a plurality of passageways converging axially into a chamber which has radial openings into another chamber defined by a conical member converging in the axial direction and having an opening at its apex to exit the mixed components, the components exiting the radial openings collide with the walls of the conical member producing shear and turbulence and subsequently spinning within the conical member and are then subjected to increased pressure in the axial direction by the converging wall of the conical member.
