  • Blade vibration test apparatus and method
    Patent number: 6679121
    Abstract: An apparatus and method for testing vibration in a bladed disk includes a motor-driven rotor upon which the bladed disk can be attached. At least one nozzle coupled with a liquid source is positioned to direct liquid from the liquid source to a position where it would impact at least one blade of the rotating bladed disk. The stress state and/or position of a rotating blade, so impacted, can be monitored to test its vibration characteristics.
    Type: Grant
    Filed: November 6, 2001
    Date of Patent: January 20, 2004
    Assignee: Test Devices, Inc.
    Inventors: H. Eric Sonnichsen, Paul H. Wawrzonek, Richard B. Connell, Borislav D. Milatovic

  • Breaker system for hydraulic fracturing fluids
    Patent number: 4382003
    Abstract: Aqueous compositions having properties making them suitable for use as a hydraulic fracturing fluids are disclosed. These compositions comprise (a) an uncrosslinked aqueous polysaccharide solution, and (b) a 4,4'-thiodiphenol. Ingredient (b) acts as a "breaker" and causes the composition to lose viscosity at a controlled rate.
