  • Patent number: 8915453
    Abstract: A self-cleaning nozzle assembly adapted for use in processing pressurized liquids, slurries, etc., which may carry with it particulate matter. A spacing between two nozzle members forms an orifice, and the size of the orifice is adjustable. The nozzle members are spring biased together to reduce the size of the nozzle orifice, but pressurized liquids processed by the nozzle counteract the spring bias force to increase the size of the nozzle orifice. When the force of the spring bias and the force of the pressurized liquid are at equilibrium, the size of the nozzle orifice is maintained. When adjusting the compression force of the spring on the nozzle members, the upstream pressure of the liquid can be adjusted accordingly. In flash evaporation systems, the nozzle can be employed to control the flash point of the liquid by controlling the pressure thereof.

  • Patent number: 8602320
    Abstract: An expansion nozzle adapted for use in processing high pressure, high temperature liquids. A spring biases a nozzle head into contact with a nozzle seat, but the high pressure liquids processed by the nozzle move the nozzle head away from the nozzle seat to form an orifice therebetween. A motor rotates the nozzle head with respect to the nozzle seat during dynamic operation to grind particles lodged in the orifice. A threaded nut and a catch mechanism are effective to adjust the spring tension and thus the force of the upstream pressurized liquid needed to operate the nozzle. The nozzle can process liquids having gasses, slurries and high concentrations of particulate matter.

  • Patent number: 8221016
    Abstract: A device and a method for continuous and adjustable dosage of fluids at low pressure. The invention is self-cleaning and low tech. It consists of a tapering dosage unit in which a filling, which allows fluids to pass in the longitudinal direction of the dosage unit, is inserted. At the outlet end of the dosage unit, a venturi tube is located which clamps the filling and thereby create a nozzle opening that fits the fluids viscosity and the pressure for a given desired dosage. When the dosage unit clogs, a flushing can be obtained by either increasing the pressure of the fluid and thereby forcing a flexible dosage unit to increase the sectional area and allow cleaning or in the same way through a mechanical opening of the dosage unit.

    Abstract: A two-handle cleaning lance includes a pair of switches which must be held closed by an operator to allow high pressure water to be directed to a discharge nozzle. A dump valve is selectively actuated to dump the high pressure water to a dump nozzle at which it will enter the environment at a much reduced pressure. The dump valve is operated by a control which monitors that the two switches are both held closed. If either switch is released, then the dump valve is moved to a dump position. The present invention ensures that an operator does not disable one of the two switches such as by taping it closed. The dump valve will not move back to its actuated position until both switches have been released and have moved to an open position.

  • Patent number: 6634570
    Abstract: A spray gun for spraying of abrasive media includes a valve operable by a nozzle needle. The valve is arranged in a gun head and has a nozzle opening. The spray gun has an operating and return device for the nozzle needle. In order for the spray gun to be self-cleaning and to be able to process several components with abrasive material, the valve includes a nozzle channel, which ends in the nozzle opening. The nozzle needle is movably supported in the nozzle channel. At least one bore laterally enters the nozzle channel to supply the media. The bore can be closed off by the nozzle needle, which has an outer diameter almost equal to an inner diameter of the nozzle channel. The length of the nozzle needle in chosen so that when the nozzle needle is in a resting state, the needle extends at least to the nozzle opening of the spray gun.

  • Patent number: 6607145
    Abstract: In a spray gumming unit, a gumming device is equipped with an ejector that sprays an adhesive substance and that is connected with a shutter element. The shutter element moves towards and away from the ejector between a position where it closes the ejector and in which a pad, fixed to one end of it, is in contact with the ejector, and a position where the ejector is left open. During the movement of the shutter element and of the pad between the ejector open and closed positions, an applicator applies an antiadhesive liquid substance on the pad.

  • Patent number: 6299688
    Abstract: A developer nozzle used to apply developer and other chemicals to a wafer in the processing of semiconductors is kept free of hardened developer or other chemicals by placing a comb-like device in a position that will let the comb be inserted into the spray holes of the nozzle when the nozzle is not in use. The teeth of the comb are tapered for easy insertion by the robot or other programmed device that controls motion of the nozzle. Although hardened developer is the principal concern in such processing, an appropriate comb can be used to maintain the cleanliness of other nozzles used in semiconductor processing.

  • Patent number: 6223997
    Abstract: A quick color change powder coating system has a powder supply, a powder pump that receives powder from the powder supply through a suction pick-up tube, a spray gun and a powder hose that connects the pump to the gun. The apparatus includes a purge air switch assembly and a first air source that provides air at purge pressure to a first inlet of the purge air switch assembly. A second air source provides flow rate air to a first pump inlet and atomizing air to a second inlet of the pump via a purge air switch assembly. Powder is drawn up the tube and into the pump by suction produced by flow rate air into the pump. A purge inlet is associated with the powder inlet to the pump. The purge air switch assembly operates in response to a purge control signal to connect purge air to the atomizing inlet at the pump and to the pump's purge inlet; whereby the pump, hose and gun can be purged at the same time.

  • Patent number: 6073861
    Abstract: A pressurized fluid cleaning system includes a fluid source, a discharge line leading to a spray discharge element, and a motor driven cleaner such as a cleaning brush to clean the spray discharge element. A sensor in the discharge line responds to fluid back pressure above a pre-established level (or to flow rate below a pre-established level) to actuate a cleaner "on" switch. Additionally or alternatively, a fluid sensor in an overflow line from the fluid source responds to fluid in the overflow line to actuate the cleaner "on" switch. The sensors are also connected to a warning device and to a delayed response system "off" switch to shut down the entire system for human intervention.

  • Patent number: 5988523
    Abstract: A pop-up sprinkler unit includes an outer cylindrical fixed housing for subsurface mounting, with a riser reciprocally mounted in a central bore of the housing for extending up through a portion of the soil. A radially retractable and expandable resilient plastic containment ring is mounted at an outlet end of the housing and engages an annular inner shoulder of the housing for retaining a coil spring and the riser in the bore. The containment ring is split to enable expansion and retraction. It has a first height throughout a first portion of its circumference and a second lower height throughout a second portion of its circumference to enable overlap during insertion of the ring into the upper end of the fixed housing. This configuration eliminates a gap at the split when the ring is in its retaining position, thereby preventing debris from entering the bore of the housing and preventing complete extension and/or retraction of the riser.

    Abstract: An extension tube system for a dust particulate dispenser and a method of using the extension tube system are disclosed. The system includes a flexible duster extension tube having a central body portion with a first diameter, a first coupling end with a larger diameter, and a second dispensing end with a smaller diameter. Additionally, the second dispensing end includes a dust particulate collection region which serves to prevent dust particulates from spilling out of the duster extension tube when such action is not desired. The first coupling end is inserted over an outlet region of a dust particulate dispenser. Additional extension tubes can be connected to the second dispensing end of an extension tube to extend the reach to an area where dust particulates must be applied. A flexible duster extension tube cleaner having a cleaning element is used to clean remaining dust particulates from within the extension tubes.
