  • Publication number: 20110291461
    Abstract: In one aspect of the invention, a degradation element includes a substrate bonded to a sintered polycrystalline ceramic. The sintered polycrystalline ceramic has a tapering shape and a rounded apex. The rounded apex has a curvature with a 0.050 to 0.150 inch radius when viewed from a direction normal to a central axis of the degradation element that intersects the curvature. The rounded apex includes the characteristic of when the rounded apex is loaded against a rock formation, the rounded apex fails the rock formation forming a crushed barrier ahead of the rounded apex that shields the rounded apex from a virgin portion of the rock formation while still allowing the rounded apex to penetrate below a surface of the rock formation.

  • Patent number: 7891453
    Abstract: In one aspect of the present invention, an energy storage system has an elastic hydraulic fluid vessel with an internal variable volume and being coupled to a hydraulic rotary mechanism. The elastic hydraulic fluid vessel has an elastic material adapted to store a potential energy within its fibers when the internal volume is increased by a hydraulic fluid. The hydraulic rotary mechanism is adapted to be accelerated by the release of the potential energy of the fibers of the elastic vessel by ejecting the hydraulic fluid from the internal variable volume into the rotary mechanism.
