  • Patent number: 8905681
    Abstract: A pneumatic conveying process transports plastic pellets from a manufacturing source to a bulk silo for storage before being delivered to the ultimate production utilization of the plastic pellets. Multiple types or multiple sources of plastic pellets can be fed through a common pneumatic conveying conduit to respective bulk silos for temporary storage with diverter valves being utilized to direct product into and out of the common conveying conduit. Expanded elbow fittings are deployed at each directional change in the conveying lines to eliminate the creation of streamers at conduit bends. The plastic pellets are conveyed at a medium velocity between dense and dilute phases to provide a gentle conveying operation. A closed loop air supply system is used for dedusting devices providing a final removal of dust and debris from the stored product before being delivered to the ultimate utilization facility.

  • Patent number: 8893923
    Abstract: Provided are methods and systems for dispensing different chemicals used for high productivity combinatorial processing. A dispense panel may include multiple inlet lines for supplying different chemicals. Each inlet line is connected to its own three-way valve that either allows the supplied chemical to flow from the inlet line towards a dispense valve connected to a dispense manifold (during dispensing of the supplied chemical) or allows another chemical to flow from the dispense valve to a waste manifold (during priming of the dispense manifold with this other chemical). Specifically, during priming a chemical supplied from its inlet line and is passed through a corresponding three-way valve and is directed to its dispense valve and then into the dispense manifold. Other dispense valves and three-way valves of the dispense panel allow this chemical to flow out of the dispense manifold, thereby priming remaining parts of the panel.

  • Patent number: 8881956
    Abstract: A device for dispensing a liquid product as an atomized spray includes a container, a depressible dispensing head for initiating emission of the spray from the device and for terminating emission of the spray from the device, and a sequential delivery valve attached to the dispensing head. The dispensing device is configured to initiate flow of gas only into the dispensing head first when the dispensing head is depressed from a first axial position to a second axial position. When the dispensing head is depressed further toward the container to a third axial position, the dispensing device allows both liquid and gas to travel from the container into the dispensing head. When the dispensing head is released from the third axial position back to the first axial position, the dispensing device first stops flow of liquid into the dispensing head before stopping flow of gas into the dispensing head.

    Abstract: A sequential delivery valve provides sequential delivery of gas propellant and liquid product from a container to a dispensing head for ejecting an atomized spray from the dispensing head. When the dispensing head is depressed, a pusher in the valve passes from a closed position wherein no liquid and no gas is allowed to travel through the valve to a partially open position where only gas is allowed to travel through the valve and eventually to a fully open position wherein both gas and liquid are allowed to travel through the valve into the dispensing head. When the dispensing head is released, the pusher passes from the fully open position back to a partially open position allowing only gas to travel through the valve and eventually to the closed position wherein no gas and no liquid are allowed to travel through the valve into the dispensing head.

  • Patent number: 6926695
    Abstract: A sealant applicator suitable for dispensing a coagulable sealant, for example a two-component fibrin sealant mixed in the applicator, employs impulse clearing to remove residual coagulated or coagulating material from the dispensing pathway and mixing chamber, if present. Impulses may be generated by manual application of a clearing member such as a plunger which can enter into the dispensing pathway to engage, dislodge and discharge residuals or can generate a gas impulse to impact the residuals to similar effect. A clearing valve having a clearing port can be operated by movement of the clearing member to provide access to the dispensing pathway.

  • Patent number: 6520377
    Abstract: A dispenser for separately packing at least two components and allowing the selective dispensing of either component or both components together via a propellant gas is provided. The dispenser includes a rigid outer vessel and an inner container arranged inside the outer vessel. The outer vessel contains one component, the inner container contains the other component and the propellant gas is arranged in at least the outer vessel. A dispensing valve is configured to be placed in selective communication with the outer vessel, the inner container, or both the outer vessel and inner container, for example, via first and/or second feed orifices, and communicates with a dispensing path. A valve actuator is provided, the dispenser being capable, when the dispensing valve is in communication with the rigid outer vessel, of dispensing substantially only propellant gas so as to clean out the dispensing path.

  • Patent number: 6461361
    Abstract: A gas-driven spray applicator particularly suitable for spray delivery of mixed fibrin sealants for surgical use has a spray nozzle wherein droplets or a stream of mixed sealant agents are entrained in a stream of gas such as sterile compressed air. Gas entrainment of the mixed sealant overcomes problems of ineffective mixing which may occur when the sealant agents are separately discharged into overlapping spray patterns. A spray tip assembly is disclosed which is suitable for attachment to an applicator body having manually dischargeable reservoirs for the sealant agents. Clogs may be cleared by suction.

  • Patent number: 6315161
    Abstract: A method and apparatus for dispensing multi-component foamable fluid plastic materials such as polyurethane foams. The apparatus includes a mixing chamber defined by an axial passage in a support body structure. The mixing chamber receives reactant fluids for mixing then allows the fluids to exit through an opening at one end of the axial passage. Two fluid inlet openings in a wall of the axial passage admit reactant fluid into the mixing chamber. Two mixing chamber fluid inlets formed in the support body structure communicate reactant fluid sources with the mixing chamber through the inlet openings. When retracted, a valve needle in the axial passage exposes the inlet openings to admit reactant fluids into the mixing chamber. When advanced, the needle closes off the inlet openings and pushes the mixed fluids from the mixing chamber. The valve needle includes three parallel helical grooves that help purge the mixing chamber of unreacted and reacted fluids.

  • Patent number: 6283329
    Abstract: An apparatus for applying a foamable fluid plastic material including reactant fluids that form a foam when heated and mixed. A reactant fluid dispenser supplies the reactant fluids to a heated applicator gun mixing chamber at a constant flow rate despite any differences in viscosity. A valve needle extends into the mixing chamber and exposes fluid inlet openings when retracted, permitting the reactant fluids to flow into the mixing chamber. When advanced, the needle closes off the fluid inlet openings and dispenses the mixed fluids. A heater prevents the gun from drawing heat energy from initial quantities of the pre-heated reactant fluids which would prevent initial quantities of the fluids from reacting properly. The valve needle is disposed in a sleeve that defines the mixing chamber and is disposed in a sleeve receptacle of the gun.
