Patent number: 12208495Abstract: 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.Type: GrantFiled: July 10, 2023Date of Patent: January 28, 2025Assignee: Caterpillar Paving Products Inc.Inventor: Daniel Jonathan Heim

Patent number: 7895985Abstract: 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.Type: GrantFiled: December 30, 2008Date of Patent: March 1, 2011Assignee: SRI InternationalInventors: Ronald E. Pelrine, Scott E. Stanford, Harsha Prahlad, Seajin Oh, Jonathan Heim, Roy D. Kornbluh

Patent number: 7705521Abstract: 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.Type: GrantFiled: April 23, 2008Date of Patent: April 27, 2010Assignee: SRI InternationalInventors: Ronald E. Pelrine, Roy D. Kornbluh, Jonathan Heim

Publication number: 20010008093Abstract: 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.Type: ApplicationFiled: March 7, 2001Publication date: July 19, 2001Inventor: Jonathan Heim
