  • Patent number: 10392123
    Abstract: A method of recovering performance of an air separation module (ASM) is described. A recovery system includes an air source providing inlet air, a filter to output clean air and a heater heating the air. The ASM is coupled to the system and comprises a hollow fiber membrane to output nitrogen enriched air (NEA) exhaust. The method comprises operating the system with the air source and heater in a default condition; measuring an initial purity of NEA exhaust; adjusting the air source and/or heater based on the initial purity; operating the system after adjusting the air source and/or heater; returning the air source and heater to the default condition; measuring a recovered purity of NEA exhaust; and determining whether the recovered purity is within tolerance. If the recovered purity is within tolerance, system operation is terminated. If the recovered purity is not within tolerance, the steps are repeated.

  • Patent number: 10337463
    Abstract: A method is presented wherein during a first condition that includes a fuel tank pressure above a threshold, a fuel tank is fluidically coupled to a fuel vapor canister while a fuel vapor canister vent path is restricted, and a degree of restriction of the fuel vapor canister vent path is modulated. Modulating the degree of restriction of the fuel vapor canister vent path allows a fuel tank to be depressurized at a controlled rate. In this way, excess fuel tank pressure can be relieved, even if a vehicle engine is not operating in a combustion mode.

  • Patent number: 10253594
    Abstract: A zone to be treated comprises a plurality of sliding sleeve valves. The sleeve defined opposed chambers charged with pressurized fluid on opposed sides of the sleeve. Valves responsive to a remote signal with no borehole intervention change the pressure balance on the sleeve to get it to open from a closed position and then close and then to reopen for production. One way this is done is by sequential pressure bleeding off from the opposed chambers. A zone having multiple such valves can be treated without need for dropping balls and subsequent milling out, which allows production to commence sooner with reduced restrictions to flow from the ball seats and without the debris associated from a milling operation.

The controller includes a clock (22) and the relationship between the required output pressure and the measured flow rate is time dependent. Parameters which define the relationship are supplied to the controller (8) from a remote data processing system (13) which analyses flow rate and output pressure data transmitted from the controller, and also pressure data from a remote sensor (10) at the critical point. At intervals, the controller (8) establishes a wireless connection with the remote system (13), to transmit logged data, and to receive parameters covering a period of time which is greater than the interval between communication sessions.

  • Patent number: 9625918
    Abstract: A fluid-pressure regulator for regulating the pressure of a fluid. The regulator includes a variable-resistance fluid element and a variable-volume fluid element located downstream of the variable-resistance element. Pressure in the fluid at the outlet of the regulator is controlled by substantially simultaneously changing the resistance of the variable-resistance element and the volume of the variable-volume element. In one example, a decrease in pressure is effected at the outlet by simultaneously increasing the resistance of the variable-resistance element and increasing the volume of the variable-volume element. Some embodiments of the regulator are particularly useful to effect long-term and high-speed pressure changes in high-resistance fluidic channel networks.

The seat separates the cavity into first and second cavity portions. The seat defines an aperture to provide fluid communication between the first and second cavity portions. The assembly includes a cover device disposed between the seat and the outlet. The cover device defines at least one hole therethrough. The cover device is movable between a rest position engaging the seat to minimize fluid communication between the aperture and the hole and an actuated position spaced from the seat to increase fluid communication between the aperture and the hole when a vacuum is created in the first cavity portion.

  • Publication number: 20150087098
    Abstract: A method for reducing an internal pressure of a vacuum chamber while preventing impurity contamination within the vacuum chamber as much as possible. The method includes: rough pumping reducing an internal pressure of a vacuum chamber (1) by using a roughing pump (2), the roughing pump (2) being a mechanical pump that is capable of reducing the internal pressure of the vacuum chamber (1) to be less than 15 Pa; main pumping reducing the internal pressure of the vacuum chamber (1) by using a main pump (3) after the rough pumping, the main pump (3) being a non-mechanical pump. Transition from the rough pumping to the main pumping is performed when the internal pressure of the vacuum chamber (1) is no less than 15 Pa.

  • Patent number: 8978692
    Abstract: A pilot valve (2) for controlling operation of a hydraulically-actuated pressure reducing valve, the pilot valve including a housing (4), and a first valve member (15) mounted in the housing for longitudinal movement along an axis relative to the housing and to a second valve member (22) in response to the outlet pressure of the pressure reducing valve. The first valve member is provided with an aperture (20) and the second valve member comprises a closure portion which varies the effective flow cross section of the aperture in accordance with relative longitudinal movement between the first and second valve members. An adjuster (26) controls the relative rotational position of the first and second valve members, the closure portion having a profile such that relative rotation between the first and second valve members causes the closure portion to vary the effective flow cross section of the aperture (20).

  • Patent number: 8973597
    Abstract: A water supply system that supplies water to a plumbing system from either a mains supply, or an auxiliary supply. In a default state, a shuttle valve is pressure balanced and couples water from the mains supply to the plumbing system via mains inlet port and outlet port, and in another state the shuttle valve is pressure unbalanced and moved so that auxiliary water is coupled to the plumbing system via an auxiliary inlet port and the outlet port of the shuttle valve. Water is drawn from an auxiliary tank and coupled to the plumbing system when two conditions exist, namely when water is demanded, as sensed by flow sensor, and when water is available from the auxiliary supply, as sensed by float system. Water pressure at the auxiliary inlet port causes the shuttle to move from the default state and couple water from the auxiliary inlet port to the outlet port and thus to the plumbing system.
