Stephen Butts has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10214972
    Abstract: Vibration assisted rotary drilling (VARD) tools that provide axial compliance and low amplitude axial displacements at the drill bit while transmitting the full rotary speed and torque of the drill string to increase drilling penetration rate. The VARD tools consist essentially of: i) an axially compliant section which transfers axial load across the tool; ii) a mechanism for opposing ends of the tool to displace axially relative to each other; iii) an energy absorbing section which dampens axial bit displacements; iv) a rotation transfer section which allows any rotation and torque applied to the drill string above the tool to be applied to the bit; and v) an optional axial force generating section.
    Type: Grant
    Filed: May 29, 2015
    Date of Patent: February 26, 2019
    Assignee: Memorial University of Newfoundland

  • Patent number: 8975315
    Abstract: The present invention relates to a stabilizer composition for halogen-containing polymers and polymer mixtures, comprising at least one metal salt of isocyanuric acid, isothiocyanuric acid or a derivative thereof, to a process for the preparation thereof, the thus produced stabilizer compositions, polymer compositions comprising the stabilizer compositions, and to methods of using the stabilizer compositions.

  • Patent number: 8831413
    Abstract: A storage tank and method for monitoring thereof is provided. The tank includes a first panel that defines a mounting surface for carrying a heating element. The heating element extends into the tank for heating liquids stowed therein. A sidewall interconnects the first panel and a spaced-apart second panel. A support extends from a bottom-facing surface of the second panel for supporting the tank in a spaced-apart relation from a nearby surface. The support further defines an upward-facing pocket for receiving a portion of the heating element. A control system may monitor the storage tank and alert a service provider of operative conditions thereof.
