  • Patent number: 8881766
    Abstract: A damper assembly for use in an industrial duct used for venting contaminated gasses having particulate matter suspended therein. The damper assembly removes precipitate from the duct that was deposited by the contaminated gas and particulate matter. The damper assembly includes an articulating member which is movable between an open position and a closed position along a first axial direction. Opposing blades are disposed on opposite sides of the articulating member. Each of the opposing blades define a distal edge and are pivotable about axes that are substantially parallel to one another. A link couples each blade to the articulating member such that the motion from the articulating member is transfer to the blades. Each link is coupled to the blade between the distal edge and the respective parallel axis.

  • Patent number: 8881761
    Abstract: A steam supply passage incorporates a pressure reducing valve and the passage further incorporates a steam ejector downstream of the pressure reducing valve. A suction portion of the steam ejector is connected to a re-evaporation tank for re-evaporating steam condensate via a suction passage. Passage steam of the pressure reducing valve is used as a driving steam for the steam ejector. In operation, re-evaporated steam within the re-evaporation tank is suctioned by the steam ejector to be mixed with the passage steam. The suction passage incorporates a check valve for preventing reverse flow of steam to the re-evaporation tank.

  • Patent number: 8875739
    Abstract: A movable valve for a valve assembly is described. The present valve comprises a plug attached to an immovable mounting flange by at least two non-resilient spider-like legs comprising first and second rigid leg segments that meet at hinging apexes positioned higher than the plug. The plug resists vertical displacement by virtue of the stiff leg segments having appropriately configured curvature and length. Actuation of the valve is through vertical displacement of the plug against the biasing forces, wherein displacement of the plug causes bowing of the legs without any stretching or change in the length of the leg segments.

  • Patent number: 8869818
    Abstract: A noiseproof vent valve for a fuel tank is provided. A damping member installed in the vent valve has at least two elastic pieces, preferably the four elastic pieces. The movement of the float is absorbed by elastic deformation of the elastic pieces, and thus the float is prevented from coming into contact with a lower end forming the bottom of a valve body. However excessively the float fluctuates, no “clicking” contact noise occurs at the vent valve. As a result, the merchantability of a hybrid vehicle sensitive to low noise can be greatly increased.

  • Patent number: 8857461
    Abstract: A process and device enabling accurate mass flow control is described. A mass flow controller can be re-specified corresponding to multiple types of actual process gases and multiple flow rate ranges, even after the mass flow controller has been shipped. Calibration gas data is derived using actual flow rate versus a flow rate setting signal to generate calibration gas data. Actual gas data is derived by measuring actual flow rate versus a flow rate setting signal for each actual gas and saving. Subsequently, prior to operating the mass flow rate control device, the characteristic data for an actual and the calibration gas characteristic data is recalled. The calibration gas characteristic data is then converted to controlled flow rate correction data based on the actual gas characteristic data that is saved to the control unit and the actual gas flow rate is corrected based on this controlled flow rate correction data.

  • Patent number: 8857467
    Abstract: The 4-way valve used to control the operation of a pneumatic motor can be pneumatically operated such as by a pilot valve. The pilot valve (20) works by creating a restriction at the high-pressure air/signal port (22) regardless of the pressure drop up-stream of the pilot valve (20) while still allowing for adequate flow once the valve (20) is actuated. An additional slide valve (24) is added to the pilot valve (20) that restricts the inlet 30 of the pilot valve (20) above the poppet valve (28) that creates a pressure drop, see FIG. 3. The extra pressure drop forces the valve (20) to snap open once the actuator pin (32) contacts the poppet valve (20) to create the hysteresis. Once the valve (20) snaps open, the slide valve (24) moves to uncover the high-pressure ports (22), removing the restriction to ensure that the main 4-way (10) fully actuates.

  • Patent number: 8851110
    Abstract: A multi-phase fluid is split in a flow splitting device that includes a feed pipe in which a flow redistribution element induces tangential motion in the phases such that the denser phase is forced to redistribute around the periphery of the feed pipe. The so redistributed flow is then split into two or more distribution conduits that are typically perpendicular to the flow direction of the feed flow. Most typically, the feed pipe is in a vertical position.

  • Patent number: 8850880
    Abstract: A valve that can be actuated by a position controller via a drive, wherein the position controller has a housing and is fastened to the valve by the housing. A first temperature sensor and a second temperature sensor are attached on or in the housing. As a result of the position of both sensors, the temperature measured using the first temperature sensor is more readily influenced by the valve and the temperature registered by the second temperature sensor is more readily influenced by the environment. If a gas leak occurs in the valve, a temperature difference occurs that is evaluated for diagnosis of a leak. The diagnostic system is particularly easy to minor implement with minimal effort.

  • Patent number: 8851115
    Abstract: Coupling holding means 50 comprising retainers 53 and retainer engaging portions 52 for holding a coupled state is provided between a socket S10 and a plug P10 of a coupler. Engaging pawl portions 54 are formed on the inner sides of a pair of retainers 53 provided on both sides of a nozzle portion 32. By causing the retainers 53 to move outwardly in a coupling operation, a gap between the retainers 53 and the nozzle portion 32 can be made small. By forming interference preventing portions 58 in the engaging pawl portions 54, the retainers 53 can be provided at a smaller interval than the outer diameter of the nozzle portion 32 whereby the coupler can be made even more compact. Further, by forming the retainers 53 higher than the foremost end portion of the nozzle portion 32, the nozzle portion 32 can be protected by the retainers 53 even in an unexpected event such as falling and damage will not extend directly to the nozzle portion 32.

  • Patent number: 8844554
    Abstract: A valve mechanism which opens in response to a high temperature includes a stopper positionable at a closed position that blocks the flow of water in a cylindrical body attached to a water supply pipe. A stopper support permits the stopper to be movable from the closed position to an open position, wherein pressure of the water in the supply pipe tends to move the stopper from the closed position to the open position. A locking unit is positionable to lock the support in a position wherein the stopper blocks the channel, and has an inclined surface inclined obliquely to the water flow direction. A heat sensitive section blocks movement of the locking unit from the locking position and includes a heat sensitive portion responsive to the temperature of an environment of the valve mechanism.
