    Abstract: A flow washer assembly includes a housing with a channel for fluid flow, a seat positioned in the channel and including an upstream surface, and a washer press fit in the channel and engaging the upstream surface of the seat. The washer may be provided with a central opening that is sized according to predefined flow characteristics. An outside diameter of the washer at least adjacent an upstream end may be greater than an inside diameter of the channel such that the washer assumes a flexed orientation when press fit into the channel. Since the washer is pre-deflected, it will deflect further as inlet fluid pressure increases, effectively keeping the fluid flow rate relatively constant. The “pre-flexing” of the washer eliminates a spike in flow rate that occurs with conventional flow washer assemblies.

    Abstract: A liquid treatment apparatus includes a supply chamber for receiving a fluid, a discharge chamber for discharging the fluid, and a cavitation generating chamber extending from the supply chamber to the discharge chamber. The cavitation generating chamber is operable to generate cavitation bubbles. A method of treating a liquid comprises directing a fluid from a supply chamber into a cavitation generating chamber by constricting the fluid through an orifice, wherein the orifice has a cross dimension that is substantially less than a cross dimension of the supply chamber, such that a fluid jet is formed. The method further includes allowing the fluid jet to expand downstream of the orifice such that the velocity of the fluid is reduced so that the jet axial velocity head at the chamber outlet is less than the difference between the static pressure within the discharge chamber and the vapor pressure of the fluid. The method also includes discharging the fluid into a discharge chamber via a chamber outlet.

  • Patent number: 9902630
    Abstract: It is to be understood that embodiments of the present invention provide apparatus and a method for pumping a liquid, for example to recirculate liquid in a liquid storage tank by means of a gas lift pump. A perforated extension at the top of a gas lift allows the apparatus to be used in circumstances where the depth of liquid in the tank may vary over a wide range. Gases other than air may be used in the gas lift, so as to change the acidity and the concentrations of dissolved gases, particularly oxygen, in the liquid. The gas may be introduced into the gas lift through a whistle that generates intense sound waves and couples them into the liquid. These features when used in combination have particular application against invasive species in the ballast water of ocean-going tankers.

Even in the case of horizontal wells where the flow and pressure variations are not apparent, the present invention can still attain a good kick information identification effect.

  • Patent number: 9592963
    Abstract: An outlet tube for a material transfer system. The outlet tube comprises a body and at least one restrictor. The body is adapted to be connected to a feed system. The body has an inner wall that defines an opening adapted to receive material from the feed system such that the body is adapted to allow a flow of the material through the opening and out of the tube. At least one restrictor extends inwardly from the inner wall of the body into the opening. The restrictor(s) is adapted to extend into the flow of the material to impede the flow. In addition, the restrictor(s) is configured to enable the material to flow around it to exit out of the tube.

  • Patent number: 9551294
    Abstract: Tracks (35), fastened to static structure of an aircraft engine nozzle, guide sliders (32) journaled in struts (27, 28) fastened to a flap (23) of the nozzle. Each slider and attached journal axle or bolt (33) is formed of cobalt, and each track slider surface (61) and journal bushings (43, 44) are formed of a nickel alloy to reduce wear from rubbing. Track slides (40, 41) are mounted to the static structure of the nozzle by blind bolts (68) having a tool recess (70) at its threaded tip to prevent the bolt (68) from turning as a nut is secured. Each slider has limited rotation due to a pin (102), thereon engaging a slot in a tab (100) of the bushing (43) to assist in inserting the slider (32) into the beveled ends of the tracks (35, 36), when mounting or replacing a flap.

  • Patent number: 9521813
    Abstract: A subsurface emitter includes a piston valve both preventing water from draining from the system, and blocking the entry of roots and soil into the emitter body. A nozzle is present at one or both ends of a vertical tube. A piston is held in a normally closed position by a spring in the absence of water pressure, covering ports in the nozzle. When sufficient water pressure in provided, the spring is compressed and the nozzle uncovers the port providing a subsurface spray of water. The spray of water is sufficient to clear mineral deposits which otherwise may accumulate and block the port.
