Abstract: The present invention discloses a unique self-aligning, quick-release coupling system capable of releasably joining any two or more of a great variety of cooperative male/female mating items to be temporarily or permanently joined, at the option of the user. Spring-biased positive ejecting forces within the female sub-assembly otherwise tending to separate these items are used to reliably capture the male component until positive separation is desired. Relatively small adjustable threshold triggering forces are required to initiate separation.In preferred embodiments, the mating members include round or polygonal cross-sections, tailored to the user's needs to facilitate keyed alignment; integrally moulded spring members, choices of dielectric materials for safe use in corrosive environments; and remote control of disengagement.

Abstract: The present invention teaches a novel internal combustion engine wherein a unique structural means of transmitting combustion-generated forces and motion is incorporated. A journalled rotor assembly having combustion cavities in each of opposing faces thereof receives a combustible fluid. A main cam carried by an output shaft which is integral with the rotor assembly drives intermittent-motion cams carried on transfer shafts. Transfer plates integral with the transfer shafts and captively movable within housings rotate into and out of the combustion cavities so as to define the variable working volumes of each cavity. With each of the firings, the rotor is caused to spin in a direction opposite with respect to the relative rotational direction of the respective transfer plates.
