  • Patent number: 6129028
    Abstract: A mechanism for steering a beam guided vehicle having four steerable wheels linked to a centrally located steering trolley guided by an electrified T-shape beam mounted on a structural roadbed. A trolley flexibly propelled by the vehicle follows the guide beam to actuate the steering of the wheels. The trolley is quickly detachable by drop-pit access for rapid change-out to periodic off vehicle servicing. Two steering arm sensor posts engaging two sockets in the repositioned trolley guarantee interchangeability of standardized repaired units.

  • Patent number: 6109040
    Abstract: A non-reciprocating Stirling-cycle machine which overcomes problems associated with high drive mechanism forces and vibration that seriously hamper reciprocating Stirling-cycle machines. The design employs Wankel rotors instead of the reciprocating pistons used in prior Stirling machines for effecting the compression and expansion cycles. Key innovations are the use of thermodynamic symmetry to allow coupling of the rotating compression and expansion spaces through simple stationary regenerators, and the coordination of thermodynamic and inertial phasing to allow complete balancing with one simple passive counterweight, which is not possible in reciprocating machines. The design can be scaled over a wide range of temperatures and capacities for use as a cryogenic or utilitarian refrigerator or to function as an external heat powered engine.
