Patent number: 10214972Abstract: 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: GrantFiled: May 29, 2015Date of Patent: February 26, 2019Assignee: Memorial University of NewfoundlandInventors: Stephen Butt, Brock Gillis, Pushpinder Singh Rana

Patent number: 8831413Abstract: 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.Type: GrantFiled: January 20, 2011Date of Patent: September 9, 2014Assignee: Envicor, LLCInventors: Gary Steven Arnold, Stephen Butts
