  • Publication number: 20200132044
    Abstract: A variable-pitch vertical axis wind turbine comprises a hub supported for rotation about a central axis and a blade pivotally mounted to the hub so as to permit relative rotation between the blade and the hub. The blade and the hub define a pitch angle therebetween. The wind turbine comprises a mechanism configured to produce reciprocating motion during rotation of the hub about the central axis. The wind turbine comprises a linkage configured to transfer the reciprocating motion produced by the mechanism to the blade so as to vary the pitch angle.

  • Patent number: 9127685
    Abstract: A vacuum pump rotor suitable for use in a vacuum pump is described for a vacuum pump that comprises a regenerative pumping mechanism. The rotor has a generally disc-shaped configuration and is mounted on an axial shaft for rotation relative to a stator of a vacuum pump. The rotor has a first and second opposing surface on which a rotor formations are disposed, each rotor formation defining a portion of a pump stage formed between the pump rotor and a stator for pumping gas from an inlet to an outlet in the same radial direction along the first and second opposing surface. A conduit is provided to interconnect the portions of the pump stage and assist with pressure imbalance that might occur on opposing sides of the rotor.

  • Patent number: 9097252
    Abstract: A scroll pump includes a pump housing, a drive shaft having a concentric shaft portion and an eccentric shaft portion connected to an orbiting scroll. The shaft is driven by a motor so that rotation of the shaft imparts an orbiting motion to the orbiting scroll relative to a fixed scroll for pumping fluid between a pump inlet and a pump outlet of the compressor. The fixed scroll has an opening through which the shaft extends and is connected to the orbiting scroll on an opposing side of the fixed scroll to the motor. An anti-rotation device is located in the high vacuum region for resisting rotation of the orbiting scroll and allowing said orbiting motion, and a bearing arrangement for supporting rotation of the concentric shaft portion and eccentric shaft portion is located in tile low vacuum region.

  • Publication number: 20140353530
    Abstract: A dual usage HCG VCSEL detector is provided with a high contrast grating (HCG) reflector first reflector that has a two dimensional periodic structure. The two dimensional structure is a periodic structure that is a symmetric structure with periodic repeating. The symmetrical structure provides that polarization modes of light are undistinguishable. A second reflector is in an opposing relationship to the first reflector. A tunable optical cavity is between the first and second reflectors. An active region is positioned in the cavity between the first and second reflectors. The photodetector is polarization independent. An MQW light absorber is included converts light to electrons. A dual usage HCG VCSEL-detector includes a high contrast grating (HCG) reflector first reflector, and a second reflector in an opposing relationship to the first reflector. A tunable optical cavity is between the first and second reflectors. An active region is positioned in the cavity between the first and second reflectors.
