  • Energy-conserving regenerative-flow valves for hydraulic servomotors
    Patent number: 4840111
    Abstract: An improved energy-conserving servoactuator has at least one valve operatively associated with a double-acting fluid-powered actuator. When a load is applied to the actuator, the pressure in one actuator chamber will be greater than in the other. If the load is "opposing" with respect to the desired direction of actuator movement, fluid is supplied to the higher pressure chamber and is permitted to flow from the lower pressure chamber. However, if the load is "aiding" with respect to the desired direction of actuator movement, fluid in the higher pressure chamber is permitted to flow into the lower pressure chamber without drawing fresh fluid from the source.

  • Slide mount for a ski binding component
    Patent number: 4264088
    Abstract: A slide mount is adapted to selectively move a plunger assembly of a ski binding relative to a detent recess component. The slide mount includes a rail mounted on the ski and having a channel aligned with the recess, a slide carrying the plunger assembly and mounted on the rail for sliding movement along the channel both toward and away from the recess, and an actuator arranged to act between the rail and slide to cause the slide to move between a first position closer to the detent recess and a second position farther from the detent recess. The actuator includes a lever pivotally mounted on the rail, and a link pivotally connected to the lever and the slide, so that pivotal movement of the lever will produce corresponding linear motion of the slide.

  • Optical fibre sensor array with temperature compensation
    Patent number: 8336389
    Abstract: An optical fiber strain sensor array comprises several sensor support panels spaced in its longitudinal direction and at least one connecting member extending in the longitudinal direction, which mechanically interconnects the sensor support panels. An optical fiber is supported by the sensor support panels and the connecting member. The optical fiber extends with the connecting member between the sensor support panels and forms a curve on the sensor support panel, the curve including at least one portion of the optical fiber that extends in the transverse direction. The width of the connecting member is substantially less than the width of the sensor support panels, such that the connecting member is capable of flexure in the transverse direction. This has the advantage that the connecting member can be flexed to take up any slack during installation of the optical fiber strain sensor array in a wind turbine blade and can be fitted to the turbine blade even if the blade has a conical shape.

  • Hydraulic amplifiers with reduced leakage at null
    Patent number: 5443089
    Abstract: An improved fluid amplifier (39) is operatively arranged in a flow path extending between a source (28, 31) of pressurized fluid (P.sub.s) and a fluid return (38) at a return pressure (R). The amplifier has at least one fluid connection (34 or 35) to a load. The amplifier has a movable mechanical member (24) operatively arranged to control the pressure at, and flow with respect to, the load. The mechanical member has a displacement range encompassing a null position and an off-null position. The improvement broadly includes a variable-impedance orifice (42 and/or 43) arranged in series with the amplifier in the low path. The impedance of the orifice is varied such that the impedance is a maximum when the mechanical member is in the null position and is a minimum when the mechanical member is in off-null position, such that flow from the supply to the return when the mechanical member is in the null position will be less than the maximum flow between the amplifier and the load.

  • Seal assemblies
    Patent number: 4597322
    Abstract: A seal assembly is arranged to contain leakage of hydraulic fluid passing between a wall opening and a penetrant rod portion passing through the opening. The seal assembly includes a sliding-seal member mounted on a portion of the rod for sliding movement toward and away from an abutment surface and a non-sliding flexible-seal member arranged between the body and the sliding-seal member. The body, flexible-seal member, sliding-seal member and rod define a sealed chamber into which such fluid will leak. The chamber communicates with a fluid reservoir through a oneway check valve. The sliding-seal and flexible-seal members are arranged in parallel with one another. In one embodiment, a spring urges the sliding-seal member to move toward an abutment surface provided on the rod. In another embodiment, movement of the sliding-seal member relative to the body is limited by facing abutment steps.

  • Failsafe valve for geared rotary actuator
    Patent number: 11926408
    Abstract: A failsafe vale provides “Hole-In-The-Wall” failsafe functionality for thin-wing aircraft control surface actuation systems having a geared rotary actuator powered by a hydraulic rotary motor. The failsafe valve is associated with the hydraulic rotary motor and mechanically connected to the control surface, and enables the flight control surface to return to an aerodynamically neutral failsafe position if electrical control and/or hydraulic pressure is lost. When the failsafe valve receives a normal command pressure from the hydraulic system, the valve is inactive and the actuation system operates normally. However, if there is a loss of electrical command capacity to control hydraulic valves and/or a loss of hydraulic pressure, the failsafe valve is activated and connects one of the motor hydraulic control lines to the case return line for the motor if the control surface is away from its failsafe position.
