  • Reducing thermal effects during leak testing
    Patent number: 10107711
    Abstract: Embodiments of the inventive subject matter include a method and apparatus for performing a leak test. A fluid flows through a first aperture of a product and at least a portion of the fluid is allowed to exit the product through a second aperture while the fluid is flowing through the first aperture. The second aperture is closed in response to determining that a first threshold parameter is reached. The first aperture is closed in response to determining that a second threshold parameter is met. Then, a leak test can be performed.
    Type: Grant

    Date of Patent: October 23, 2018
    Assignee: InterTech Development Company

  • Extending clamp
    Patent number: 6422550
    Abstract: A hydraulically driven extending clamp is disclosed having a pivoting main body which includes an extendable clamping rod disposed therein. The clamping rod extends above the pivot and is extended by air pressure and retracted by a spring internal to the clamping rod. A retaining member extends through a slot in the clamping rod and forms a travel limit stop as well as a retraction spring contact point. A hydraulic cylinder pivots the main body in seesaw-like fashion to apply clamping forces.
