  • Patent number: 9795938
    Abstract: There is provided a method and apparatus for indirect magnetic treatment of fluids/gases, where a magnetic or electromagnetic field having a certain dimension, geometry and flux density is, in a first step, applied to a working fluid/gas to obtain the directly magnetized fluid/gas. Then the directly magnetized fluid/gas is used in a second step as a magnetizer or a magnetic treating agent for magnetizing indirectly the normal non-magnetized fluid/gas by mixing the directly magnetized fluid/gas and normal non-magnetized fluid/gas in accordance with a predetermined mixing ratio and mixing method between the directly magnetized fluid/gas and normal non-magnetized working fluid/gas. Afterwards, the resultant mixed or indirectly-magnetized fluid/gas is used in the proper application directly or stored in a storage tank for later use.

    Abstract: A high shear mixer in a holding tank is used in a continuous flow process. Flow rate of material into and out of the holding tank establishes residence time in contact with shearing elements. A batch shear mixer is used in a tank that has continuous flow into the bottom and out of the top. A level controller controls a valve or a positive displacement pump at the inlet. The mixing chamber is sized for the maximum needed residence time, slowing the flow increases the residence time. In an open tank lower inlet pump and upper outlet pump are coordinated.

    Abstract: The automatic analyzer for the assay of liquid samples comprises an exchangeable mixing chamber whose mixing chamber is tapered toward the bottom and is provided with an outlet which is followed by a bore which connects the mixing chamber to an outlet opening. An abrupt transition is formed between said bore and the outlet opening for the analyzed liquid. The abrupt transition is a restriction which serves as a collecting trap for disturbing particles, e.g. coaguli, which might lead to undesirable obstructions elsewhere. Those particles which cannot be flushed away laterally by another outlet opening are eliminated by removing the mixing chamber from the base and blowing it through. A sealing ring serves for a tight seal between the plane bottom of the mixing chamber and the connection. A fluid sensor is provided in order to detect the sample liquid flowing through this connection.

    Abstract: In a process for separating impurities from a raw gallium material containing impurities, a process for refining gallium comprising progressively solidifying a raw gallium material provided in a liquid state inside a vessel while applying stirring, such that the diameter of the tubular solidification boundary gradually advances from the inner wall plane of the vessel towards the center of the vessel to reduce the diameter of the tubular solidification boundary, and separating the liquid phase remaining in the central portion of the vessel from the solidified phase before the entire raw material inside the vessel is solidified. The process above is repeated as required by using, as the raw gallium material, the solidified phase from which the liquid phase is separated. A metallic gallium favorably used for the preparation of a compound semiconductor can be obtained by analyzing the impurity concentration of the impurity-concentrated Ga separated from the solidified layer.

Power units are attached to the device in order to make it self-contained. A rotatable outlet allows slurry to be discharged to a tanker truck or other carrier. A vertical placement device is used for placing the frame, tank body, and power unit in a working position once at a jobsite and a raised position when pulling the apparatus on a highway.

  • Patent number: 6290385
    Abstract: A device for the homogenization of a liquid contained in a container comprises a pipe device possible to stick down in the container, said pipe device including an inner pipe (5′) and an outer pipe (6′). A cup-like collar (15) with a bottom plate (16) and a circumfering flange (17) is mounted on the inner pipe. There are openings (18, 18′) in the flange (17) which co-operate with analogous holes (19, 19′) in the outer pipe (6′). When a hole (19′) is adjusted in flush with an opening (18), the return liquid is ejected from a ring-shaped gap (9) in a radial jet. When a hole (19) is adjusted in a position distanced from an opening (18), the return liquid which passes the hole will meet the inside of the flange (17) and be deflected in a upwardly directed flow in the container. By setting the collar (15) in a suitable position, optimum homogenization of the liquid may be attained.

  • Patent number: 6186657
    Abstract: An apparatus and method for mixing or dissolving a particulate solid or gel in a liquid to form a solution of substantially homogeneous concentration. The apparatus includes a vessel which has a cylindrical portion integral with a large diameter end of a frustoconical portion. The vessel has a series of liquid inlets, located in a wall of the cylindrical portion and frustoconical portion, and a solution outlet formed at a small diameter end of the frustoconical portion. An elbow-shaped nozzle is connected to each of the liquid inlets, the nozzles directing liquid flow parallel to the inside surface of the vessel. The apparatus also includes a venturi adjacent the outlet in order to create a low pressure zone downstream of the venturi to suck or draw liquid or solution from the vessel.

  • Patent number: 5975751
    Abstract: A motorized mixer for mixing bone cement for use in attachment of prosthetics and method for using the mixer. The mixer comprises a mixing chamber, a liner in the mixing chamber, an impeller within the liner, a motor for driving the impeller and programmable memory mechanics for regulating the operations of the motor. The liner comprises a basket for receiving vials of bone cement catalyst and a mixing bowl for receiving the bone cement powder. Preferably the two are permanently attached to one another. The mixing bowl is also used for mixing the two components together to produce the bone cement. During mixing the mixing bowl is maintained under a vacuum to withdraw fumes from the bone cement and to prevent gases from being mixed into the bone cement. Once mixing is complete, a U-shaped trap door releases the mixed bone cement from the mixing bowl, through a discharge tube and into a bone cement cartridge.

  • Patent number: 5899561
    Abstract: A system for applying accurately metered, minute quantities of concentrated additives from bulk sources of supply to successive masses of material presented for treatment includes a pass-through chamber within which separate streams of a liquid carrier and the additive substance are merged together. As the liquid carrier passes through the chamber, the additive, in either dry or liquid form, is likewise directed into the chamber in a metered flow to incrementally combine with the liquid stream and form the combined product. A suction pump at the downstream end of the chamber draws the prepared product out of the chamber and advances it toward an ultimate delivery site. The carrier liquid is prevented from accumulating into a pool within the chamber by the suction pump that cooperates with the upright orientation of the chamber to cause the carrier liquid to swirl smoothly through the chamber.
