  • Patent number: 11118580
    Abstract: An absolute proportioning pumping system includes an electric motor assembly powering a first pump at a first flow rate and powering a second pump at a second flow rate. A proportioned fluid output includes a first fluid pumped by the first pump and a second fluid pumped by the second pump. The pumping system provides a desired ratio of the first fluid to the second fluid at the proportioned fluid output, relatively independently of pressure and flow rate at the output. In accord with further embodiments, a pump and motor assembly is mounted to and generally surrounded by a liquid tank. The pump and motor assembly may include a pair of fixed ratio outputs driven from a common motor, or may include a single variable output pump either slaved to a master pump or controlled through a timed bypass valve to control output flow rate.

  • Patent number: 8974111
    Abstract: A method and apparatus for combining and mixing together a plurality of liquids to form a blend. The invention discloses reservoir supplied intermittently operated servo driven pumps, and optionally discrete liquid flow meters, and precise, encoded, fast-acting flow shut-off devices to create and define repeated time synchronized ratio defined doses of the liquids. One or more liquids, designated secondary streams, are synchronously dosed into a secondary streams injection assembly which is located generally at the suction port of the primary liquid stream dosing pump. The primary stream pump, during its synchronized intermittent operation, withdraws ratio defined primary stream and secondary stream liquids from the injection assembly. The primary stream pump serves also to propel the combined liquids ratio dosed streams into and through mixing structure on the discharge of the primary stream pump.

  • Patent number: 8367004
    Abstract: Apparatus, systems and methods are provided that utilize microreactor technology to achieve desired mixing and interaction at a micro and/or molecular level between and among feed stream constituents. Feed streams are fed to an intensifier pump at individually controlled rates, e.g., based on operation of individually controlled feed pumps. The time during which first and second feed streams are combined/mixed prior to introduction to the microreactor is generally minimized, thereby avoiding potential reactions and other constituent interactions prior to micro- and/or nano-scale interactions within the microreactor. Various microreactor designs/geometries may be employed, e.g., “Z” type single or multi-slot geometries and “Y” type single or multi-slot geometries. Various applications benefit from the disclosure, including emulsion, crystallization, encapsulation and reaction processes.

  • Patent number: 6543490
    Abstract: A method and apparatus (10) for custom blending spray paints. A customer provides a sample (S) of a color to be matched. The sample is tested on a spectrophotometer to determine the colors needed to match the sample; or if the paint formula is known, it is entered into the apparatus. A computer control (16) causes metered quantities of each colorant to be pumped from a reservoir (50) to a manifold (68). From the manifold, paint is injected through a filling head (46) into a discharge valve (V) and dip tube (P) of a precharged aerosol container (C) to be filled. Solvent from a tank (74) is used between a final injection of colorant to flush out the manifold and a dip tube (P) of the container. After the colors have been injected into the container, the container is shaken so that the colors intermix with each other to produce a paint of the desired custom color which is readily sprayed from the container.
