  • Patent number: 10989175
    Abstract: The present invention utilizes operation of a valve actuator to generate electrical power. A portion of the mechanical energy generated by operation of a valve actuator is converted to electrical energy. The mechanical energy may be converted to electrical energy at the same time as the valve actuator is operating or the mechanical energy may be stored for later conversion. A valve actuator may be operated manually, electrically, pneumatically, or hydraulically. Generated electrical energy may also be stored.
    Type: Grant
    Filed: February 27, 2018
    Date of Patent: April 27, 2021
    Assignee: Flowserve Management Company

  • Patent number: 4705343
    Abstract: A protective dome (14) is provided for a zoom telescope (12) which is located therein. Telescope (12) can be used as an attachment to a prime imaging system (22) such as a FLIR (forward looking infrared). The dome (14) is mounted so that its center of curvature (16) is inboard of the outer skin (18) of the aircraft in order to reduce aerodynamic drag. The objective lens (24) of the telescope (12) is decentered with respect to a common axis (29) and the lenses of the zoom lens group (26) are tilted with respect to the common axis (29) to compensate for aberrations introduced by the decentered dome (14).
