  • Method and apparatus for measuring electrochemical corrosion potential inside small shallow cracks
    Patent number: 7060177
    Abstract: A method of measuring an electrochemical corrosion potential (ECP) of a material specimen using a detecting device including an ECP detecting array is provided. The method includes locating an offset spacer in close contact to a face of the ECP detecting array, locating the material specimen within the detecting device with a measurement face in close contact to the offset spacer, establishing a flow through the detecting device, and measuring an electrical potential between the detecting device ground and an electrode wire.
    Type: Grant
    Filed: March 28, 2003
    Date of Patent: June 13, 2006
    Assignee: General Electric Company
    Inventors: Robert James Law, David Phillip Siegwarth
  • Particle build-up prevention in flowing systems
    Patent number: 7028701
    Abstract: A system serves to prevent or remove particle build-up in flowing systems, wherein a fluid flows in a conduit to a valve body. A mechanical shock is periodically generated in the valve body that is of a sufficient magnitude to disturb any particle attachment in the conduit or the valve body. The shock may be generated via direct impact with the valve body or passively using the fluid flowing in the conduit.
