Abstract: A wheel-equipped carrying case can be carried by hand or rolled along the ground Using an extensible U-shaped handle conveniently stored when not in Use. The extensible handle slides through holes in substantially rigid end walls into a pair of storage tubes in the interior of the case.          Wheels are rotatively attached to ends of the storage tubes extending beyond one end wall.  For added stiffness each end wall includes a flange around the periphery of the  wall  with a groove therein. The grooves accommodate the free ends of the side and bottom walls of the case during assembly.  In an alternative embodiment, the extensible handle telescopes into tubes mounted on the bottom of the case and wheels are attached to the end wall opposite the end wall through which the extensible handle projects.  One or more pivotally mounted support frames on the bottom of the case wheels allow the case to rest in a level position when it is not being carried or rolled. In another alternative embodiment the extensible handle is stored within a larger-diameter tube mounted on the bottom of the case with four metal or two plastic brackets, and is capable of being locked in extended position by spring-loaded buttons which pop up through holes in the handle tubing and storage tubing when the handle is fully extended.

Filed: 1991-05-10
Abstract: The present invention teaches an engine system apparatus and method that converts pulsed electromagnetic energy into mechanical force and motion, The engine apparatus (100) combines the reciprocating action of an internal combustion engine and utilizes electrical energy to produce a magnetic field that initiates a repelling power stroke that is maintained in a reciprocating state by a movable magnet (500) that is attracted to a stationary electromagnet member (402) of the system. An electrical power source (301) is pulsed ON to repeatedly produce the repelling power stroke and pulsed OFF to repeatedly allow the movable magnet (500) to attract to the stationary electromagnet (402). The underlying principles of the electromagnet engine allow engine configurations to be built having one stationary electromagnet and one movable permanent magnet.

Filed: 1992-11-27
Abstract: A hook for gripping chain is asymmetrical so that the effective chain length can be adjusted to a part link tightness. The attachment end of the hook is offset from the plane of the hook end, which includes the slot for receiving a link of a chain. If the chain enters from one side of the hook, the chain and hook nave a different angle than when the chain enters from the other side of the hook. The resulting change in angle and hence the way the hook interferes with the chain changes the length of chain required for the chain to reach the slot.
