  • Patent number: 8135245
    Abstract: A fiber optic sensing system comprises a housing disposed in a flow path, and a fiber optic sensor. The fiber optic sensor comprises an optical fiber secured in the housing, a Bragg grating, a light source for transmitting light to the optical fiber, and a detector for detecting light filtered by the Bragg grating of the optical fiber and monitoring wavelength changes of the detected light. The fiber is substantially perpendicular to the flow path. The housing defines an opening at an upstream side to allow flow through the flow path to exert a pressure on the optical fiber and cause a deformation of the Bragg grating.

  • Publication number: 20110210513
    Abstract: A rotary machine comprises a housing, a rotor that is rotatably disposed within the housing and having an axis about which the rotor may spin, and a seal disposed upon the housing. The seal comprises a support disposed on the housing and a plurality of flexible non-metallic bristles that extend from the housing and engage the rotor, such that the seal provides a barrier to fluid flow between a first region located in a first axial direction from the seal and a second region located in an opposite axial direction from the first region. The first region is filled with a bearing liquid and the second region is filled with a process fluid.
