    Abstract: A method of compressing gas includes maintaining a volume of gas at a first pressure within a first chamber. Pressurized liquid is forced into the first chamber through a nozzle having a curved profile. Based on the Coanda effect, the liquid compresses the volume of gas to a second pressure greater than the first pressure. The liquid is separated from the gas in a second chamber while maintaining the gas at the second pressure to provide compressed, dry gas.

    Abstract: The compressor compresses gas in capillaries leading to a radially distant annular container space. Centrifugal force acts on gas bubbles entrained between liquid slugs moving radially outward through the capillaries which may be radial, tangential or continuously curved. Compressed gas is collected in the annular space. A gas-liquid emulsion is fed to the capillaries by an inboard emulsification device. The emulsification may include a vortex generator, an ejector or a venturi injector, all feeding the gas-liquid mixture into the inboard ends of the capillaries. The capillaries are formed in a series of discs, coaxially stacked with outer disc ends open to the annular space. Capillary inlets may be perpendicular, tangential or may define a venturi jet.

  • Publication number: 20140377084
    Abstract: A method for operating a liquid ring vacuum pump employs taking vibration measurements of the pump and comparing the measurements with a prescribed cavitation threshold. In addition, a measurement representing the liquid content in the gas to be conveyed is taken. This measurement is compared with a prescribed threshold. The rotational speed of the liquid ring vacuum pump is reduced if the prescribed cavitation threshold has been exceeded and the liquid content is less than the prescribed threshold. The rotational speed is increased if the prescribed cavitation threshold has been exceeded and the liquid content is greater than the prescribed threshold. A liquid ring vacuum pump is designed for implementing the method. Due to the regulation depending on the oscillations of the pump, the pump can be operated near the cavitation boundary without any risk of damage.

    Abstract: Fluid pumping system and method provide a pumping chamber with inlet and outlet ports. The pumping chamber is in thermal communication with a thermal system for alternating the gas temperature inside the pumping chamber between heated and cooled states. A first valve controls a first fluid communication between the pumping chamber and the external environment, and a second valve controls a second fluid communication between the pumping chamber and the fluid container. The pumping chamber and the valves cooperate to generate a vacuum and a negative potential pressure of the gas inside the pumping chamber by the effect of the gas temperature alternation when the gas passes from a heated state to a cooled state and by controlling the first and second fluid communications. The generated vacuum and negative potential pressure inside the pumping chamber enable pumping of the fluid from the fluid container inside the pumping chamber.

    Abstract: A fluid mover includes a hollow body with a straight-through passage of substantially constant cross-section with an inlet end an outlet end for the entry and discharge respectively of a working fluid. A nozzle substantially circumscribes and opens into the passage intermediate the inlet and outlet ends. An inlet communicates with the nozzle for the introduction of a transport fluid, and a mixing chamber is formed within the passage downstream of the nozzle. The nozzle internal geometry and the bore profile upstream of the nozzle exit optimise the energy transfer between the transport fluid and working fluid. Working fluids are atomised to form a dispersed vapour/droplet flow with locally supersonic conditions within a pseudo-vena contracta, resulting in the creation of a supersonic condensation shock wave within the downstream mixing chamber by the condensation of the transport fluid. Methods of moving and processing fluids using the fluid mover are also disclosed.

  • Patent number: 8282772
    Abstract: A method for processing wastewater includes the steps of introducing air and a liquid into a pump, and subjecting the air and liquid to high heat and pressure; delivering the heated and pressurized air and liquid from the pump to a gas and liquid separator to separate the air from the liquid; expanding the air from the gas and liquid separator through a nozzle to accelerate the air as it expands; injecting at least some portion of the wastewater to be processed into the air from the nozzle in an entrainment section downstream from the nozzle to entrain the wastewater into the air; passing the liquid portion from the gas and liquid separator through a valve to lower the pressure of the liquid to achieve flash evaporation of the liquid to produce water and steam; introducing the water and steam produced from the valve into the air and entrained wastewater in the entrainment section, to enhance entrainment of water into the air; and delivering the air and entrained wastewater from the entrainment section to an i

  • Publication number: 20120237366
    Abstract: A vacuum prioritization system for a vehicle is disclosed. In one example, use and availability of vacuum provided via vacuum sources is allocated to higher priority vacuum operated actuators when a pressure in the vacuum system exceeds a threshold pressure. The lower priority vacuum operated actuators have access to vacuum supplied via the vacuum sources when pressure in the vacuum system is less than a threshold pressure. The approach may allow higher priority actuators to operate for an extended amount of time.

  • Patent number: 8246315
    Abstract: A system and method for pumping an underground drip includes a pump barrel housing with a plunger and an elongated stroke actuator cylinder sealed to the pump barrel that vertically reciprocates the plunger. The pump barrel and plunger are preferably vented to avoid vacuum lock during pumping. The plunger pumps the fluid located in the drip upwardly to a low pressure tank or a pressurized surface vessel. A ball valve may be screwed onto the siphon line to allow for insertion and removal of the pump barrel and seals the siphon line if the pump is removed. A stuffing box seals the pump barrel to the upper end of the siphon line to prevent air from entering the system. The stuffing box also allows the pump depth to be easily adjustable by sliding the pump in until the pump tags bottom and then tightening at any point needed.

  • Publication number: 20120205293
    Abstract: This disclosure features a system for processing microspheres. A vessel contains a suspension of solidified microspheres comprising polymer and an active agent. A hydrocyclone has a fluid inlet, a first fluid outlet and a second fluid outlet. The fluid inlet is in fluid communication with the vessel and receives the suspension. The second fluid outlet contains a flow of the suspension having concentrated microspheres. The first fluid outlet contains a flow of a relatively large amount of liquid compared to the flow from the second fluid outlet. Also featured is a method of processing the microspheres using the hydrocyclone.

    Abstract: An inflation device for inflating containers having a body with an air channel therein being in the form of a venturi tube. A first inlet is provided in the body, being in communication with the air channel, to allow compressed air to flow into the air channel. An outlet is provided in the body, being in communication with the air channel, to allow the air to exit the air channel for inflating a container joined to the outlet. A second inlet is provided in the body, being in communication with the first inlet, to allow ambient air to be sucked into the air channel as a result of the compressed air flowing in the air channel and passing through the venturi tube. A self-closing valve and sensor means are also provided.

  • Publication number: 20120057992
    Abstract: A method and apparatus for providing a Boiling Water Reactor (BWR) jet pump slip joint internal seal in the interface between an inlet mixer and a diffuser of a jet pump assembly. The internal seal provides an effective means of mitigating leakage and slip joint flow induced vibration (FIV) between the inlet mixer and diffuser to reduce damage to many of the jet pump assembly components that may otherwise be damaged by FIV. A metallic seal of the slip joint internal seal flares out to conform the internal seal to a range of gap sizes, and may be compressed or spring back to nominal dimensions as thermal expansion and contraction occurs. The internal seal is also self-expanding/self-tightening, as the internal seal flares further outward as a result of the internal pressure caused by flowing fluids in an operating jet pump assembly.
