Abstract: A system is proposed for transmitting energy and/or data between a vehicle body and a removable part, a first core half having a pin and a pin ring which extend into a second core half to thus improve an inductive coupling.

So that the pin does not protrude when a movable part is removed from a vehicle, in a further development, a ring is provided with bore holes and an annular spring which ensure that all primary-side transformer parts terminate flush with the vehicle floor. The improved inductive coupling makes it possible for the core halves to be made predominantly of an iron material.

Abstract: A door system for a cold storage locker has increased resistance to damage when by including resilient door panels that flex when hit by a forklift. A high degree of insulation is achieved by the choice and thickness of the resilient foams therein. Also, the resilient door panels are magnetically attracted to a gasket seal on a doorframe to provide an affirmative seal.

Abstract: A resilient, insulated door panel for a sliding door includes a resilient core protected by a compliant outer covering with a seal disposed about the perimeter of the panel. The panel has sufficient resilience to recover from an impact that temporarily deforms it, yet has sufficient rigidity to transmit a compressive force needed for effectively setting the seals. Much of the core is filled with air to not only provide effective insulation and resilience, but to also provide an extremely lightweight door panel that can be operated to travel rapidly along an overhead track. Some embodiments include relatively rigid backup plates that provide a solid foundation to which the perimeter seals can be attached. The backup plates are segmented so as not to completely restrict the flexibility of the door panel.

Abstract: A weatherproof sliding closure such as a window, door or hatch, especially suitable for closing openings in a marine environment, is disclosed. The closure is mounted top and bottom on bearing assemblies via camshafts extending through the closure and rotatably mounted in the assemblies. The bearing assemblies travel along fixed top and bottom guideways to move the closure between open and closed positions with respect to the closure opening. Cam portions of the shafts act against internal portions of the closure itself, serving as cam followers, when the camshafts are rotated in unison in the same direction through operation of a closure handle and drive train interconnecting the camshafts internally of the closure. This causes the closure to shift laterally on its bearing assemblies into sealing engagement with a closure frame defining the closure opening.
