  • Patent number: 6840404
    Abstract: A metering system for controlling the flow of a fluid is disclosed. The metering system comprises a metering device, two input valves that actively control flow of fluid into the metering device, and two output valves that actively control flow of fluid from the metering device. The input and output valves are selectively opened and closed to cause metered amounts of fluid to be dispensed from the metering device through the output valves.

  • Patent number: 6705537
    Abstract: An apparatus imparts movement to a fluid dispersing nozzle with a mechanism for converting rotational movement about an axis of rotation into orbital movement about the axis of rotation, and an elongate member is connectable to the mechanism at one end and is connectable to a fluid nozzle at an opposite end from the mechanism. The orbital member provides orbiting movement of the opposite end in response to rotation of the mechanism about the rotational axis, and provides stationary centered positioning of the opposite end in response to a non-rotating mechanism. A speed multiplier transmission or gearbox can be provided between the motor shaft and drive spindle if desired. A separate mixer is positionable within the member and is moveable longitudinally with respect to the member during use. The mixer includes a valve member connected to one end for movement relative to a valve seat defined by an inner surface of the cone.

  • Patent number: 6695923
    Abstract: A multiple orifice applicator system for dispensing a plurality of rows of fluid material onto a work piece is disclosed. A source of fluid material is in fluid communication with the multiple orifice applicator. The multiple orifice applicator is mounted to a robotic arm, which positions the multiple orifice applicator relative to the work piece to enable the multiple orifice applicator to dispense fluid material onto the work piece. Fluid material is caused to flow from the source of fluid material into the multiple orifice applicator. The fluid material enters the multiple orifice applicator through an inlet port and is dispersed and spread out in a dispersing chamber. The fluid material is dispensed onto the work piece through a plurality of outlet orifices in the multiple orifice applicator.

  • Patent number: 6691932
    Abstract: An applicator dispenses a pressurized fluid to a workpiece to be processed with an elongate housing having a first end and a second end. An enlarged annular flange extends radially from adjacent the first end of the housing and is connectable to a source of pressurized fluid. A tapered cone is formed on the second end to define a reduced diameter relative to the housing to enable streaming of the pressurized fluid to be applied. A separate mixer is positionable within the housing. Preferably, the mixer is moveable longitudinally with respect to the housing during use. The mixer includes a valve member connected to one end for movement relative to a valve seat defined by an inner surface of the cone. The valve member moveable between an opened position and a closed position. A piston is connected to an opposite end of the mixer from the cone to move the mixer longitudinally within the housing. The piston is moveable within a chamber between first and second end limits of movement.

  • Publication number: 20010046181
    Abstract: An apparatus for mixing a plurality of fluids to form a mixture of predetermined mixture ratios. The fluids are mixed from a plurality of sources, wherein the ratios are controlled by metering cylinders, and each cylinder is in fluid communication with a single fluid source. Each metering cylinder is operated by a corresponding lever, wherein each lever provides individual control over the stroke of each corresponding metering cylinder. The levers are connected to a single actuator for movement in unison, and for greater control in delivering and maintaining the desired mixture ratios of fluids to a receiving chamber.

  • Patent number: 4756625
    Abstract: A mixer for mixing fluid materials such as an adhesive resin and a catalyst as the materials flow from separate supply sources to a dispensing nozzle includes a disc like rotor having a plurality of balls of uniform diameter fixedly mounted in the rotor to project symmetrically from opposite sides of the rotor. The rotor is driven in rotation within a cylindrical chamber having walls providing small clearances for the rotor, the chamber having a fluid inlet and a fluid outlet in the opposed chamber end walls coaxial with the rotor. The balls are arranged in a pattern which thoroughly mixes the fluid while imposing a minimum restriction to the flow of fluid through the mixer.
