  • Patent number: 12208495
    Abstract: A tooling for removing a bit holder from a base block of a milling drum. The tooling includes a bracket, a pry tool, and an actuation member. The bracket is configured to be engaged with the bit holder and defines an impact surface to receive one or more impacts. The pry tool has a portion configured to be positioned between the bit holder and the base block. The actuation member is movably engaged with the bracket and is actuatable to contact and exert a pushing action on the pry tool to move and advance the portion of the pry tool into an interface defined between the bit holder and the base block. When the impact surface receives the impacts, impact components are correspondingly transferred to the pry tool to supplement the pushing action for a removal of the bit holder from the base block.

  • Patent number: 7895985
    Abstract: Combustion devices described herein comprise a compliant combustion chamber wall or segment. The compliant segment deforms during combustion in the combustion chamber. Some devices may include a compliant wall configured to stretch responsive to pressure generated by combustion of a fuel in the combustion chamber. A coupling portion translates deformation of the compliant segment or wall into mechanical output. One or more ports are configured to inlet an oxygen source and fuel into the combustion chamber and to outlet exhaust gases from the combustion chamber.

  • Patent number: 7705521
    Abstract: The present invention relates to mechanical-electrical power conversion systems. The systems comprise one or more electroactive polymers that convert between electrical and mechanical energy. When a voltage is applied to electrodes contacting an electroactive polymer, the polymer deflects. This deflection may be converted into rotation of a power shaft included in a motor. Repeated deflection of the polymer may then produce continuous rotation of the power shaft.

  • Publication number: 20070164641
    Abstract: The invention describes devices for performing thermodynamic work on a fluid, such as pumps, compressors and fans. The thermodynamic work may be used to provide a driving force for moving the fluid. Work performed on the fluid may be transmitted to other devices, such as a piston in a hydraulic actuation device. The devices may include one or more electroactive polymer transducers with an electroactive polymer that deflects in response to an application of an electric field. The electroactive polymer may be in contact with a fluid where the deflection of the electroactive polymer may be used to perform thermodynamic work on the fluid. The devices may be designed to efficiently operate at a plurality of operating conditions, such as operating conditions that produce an acoustic signal above or below the human hearing range. The devices may be used in thermal control systems, such as refrigeration system, cooling systems and heating systems.

  • Publication number: 20010008093
    Abstract: The present invention is a clipless pedal system for bicycles. Structurally, the present invention includes a pedal platform and two cleat retainers. The cleat retainers have hooked ends and are held against opposite sides of the pedal platform. A resilient loop encircles the pedal platform, holding the cleat retainers against the pedal platform. The ends of the cleat retainers may pivot away form the pedal platform by elastic deformation of the loop, allowing insertion of a cleat attached to a cycling shoe.
