  • Patent number: 6766831
    Abstract: An eductor (1) for mixing liquids, e.g. a concentrated solution into water, has a flow passage (16) for a first liquid into which a dispensing passage (18) for a second liquid opens so that in use the second liquid is drawn into the flow of the first liquid. The dispensing passage (18) including a flow restrictor portion provided by a groove (22) extending on the periphery of a restrictor plug (19) removably received in a socket (21) of the eductor body. The groove (22) and the wall of the socket (21) define the flow rate in the dispensing passage. The plug (19) has a plurality of the grooves (22) and is selectively insertable into the socket in a plurality of positions, the grooves providing respectively different flow rates of the second liquid.

  • Publication number: 20040065373
    Abstract: A mixing and dispensing apparatus wherein a liquid concentrate is metered into a diluent stream of an eductor in a precise manner. A needle valve is employed in conjunction with a cam member and the cam member includes slopes of varying degrees. In this manner, a wide range of dilution rates can be accomplished with only a single revolution of the needle valve. The apparatus is particularly useful in mixing and dispensing chemical concentrates such as cleaning and sanitizing materials.

  • Publication number: 20030106598
    Abstract: A liquid dilution device is provided to prevent choking at a jet for adjusting the flow amount of a special liquid. In the liquid dilution device in which the special liquid from a liquid supply passage 33 of a liquid intake device 29, is introduced to a diluent passage 12 formed in a main body 10 through a jet 22, an air intake opening 37 and a plug 38 to open and close the air intake opening 37 are provided at the liquid intake device 29 to connect the liquid supply passage 33 and atmospheric air. At the state that air from the air intake opening can be introduced to the diluent passage 12 through the jet 22 with the plug 38 opened, high velocity air passes through the jet 22 due to negative pressure generated at the diluent passage 12, by making water pass through the diluent passage 12. Due to the high velocity air, the special liquid stuck to the jet 22 is removed and the jet 22 is cleaned.

  • Patent number: 6471141
    Abstract: A hose sprayer assembly in accordance with the present invention includes a trigger body which is rotatably mounted within a housing. The housing is formed with an inlet orifice, an outlet aperture and an aspiration orifice, and further includes a deflector plate which is fixed to the outer surface of the housing proximate the outlet aperture. The trigger body includes a inlet port, an outlet port in fluid communication with the inlet port, and an aspiration port in fluid communication with the outlet port. Selective alignment of the trigger body places the inlet port and outlet port in fluid communication with the respective inlet orifice and outlet aperture of the housing. This yields a water only stream out the housing outlet aperture when water is forced through the assembly. Similarly, the body can be aligned to place the aspiration port in fluid communication with the aspiration orifice of the housing.

    Abstract: An apparatus for mixing fluids includes a housing which is mounted in line with a conduit carrying a primary fluid. A deformable member is mounted in the housing and an inlet conduit carrying a secondary fluid communicates with the deformable member. An adjustment knob adjusts the width of the deformable member, thereby adjusting the venturi effect created by the deformable member in the flow of primary fluid and adjusting the flow of secondary fluid which flows into the deformable member and is induced out of the deformable member through a plurality of holes to mix with the primary fluid. A system is provided with the fluid inductor apparatus and includes a sensor at the fluid outlet to generate a signal to control the geometric profile of the deformable member to adjust mixing of the fluids.

  • Patent number: 6418957
    Abstract: The EVRU is essentially an eductor, configured and designed, to capture and recover hydrocarbon fluids (gases and/or liquids) and/or other vapors and recombine and reinject into the system so that all the fluids are combined into a closed system to reduce or eliminate emissions (Greenhouse gases, VOC's, HAP's, CO, NOX and any other air pollutants). A measured, known volume of higher pressure fluid is fed into the eductor which draws measured, known volumes of lower pressure, hydrocarbon fluids and/or other vapors from emission (Greenhouse gas, VOC, HAP, CO, NOX and any other air pollutant) sources, combining the higher pressured fluids with the lower pressured fluids to an intermediate pressured combination fluid that is injected back into existing process equipment to close the system and prevent or minimize harmful emissions (greenhouse gases, VOC's, HAP's, CO and any other air pollutants).

  • Patent number: 6405759
    Abstract: An in-line mixing apparatus for the substantially continuous production of size to be supplied to a glass fiber forming process. The in-line mixing apparatus comprises a plurality of stages wherein the first stage is a static mixing device in which sizing components are carefully metered into a flow of water or other carrier fluid, and blended together. A second stage, hydrolyzer, connected to the first stage, provides a chamber in which the blended water and size materials are allowed to chemically react as they move therethrough. A second static mixing device may be connected to the output of the hydrolyzer if additional components need to be added, or if additional mixing of the materials blended in the first stage and reacted in the second stage is necessary. The output of the in-line mixing device may be piped directly to the size applicators of the respective fiber producing operations.
