Abstract: A base is attachable to a first object and a bar is attachable to a second object. A pivot lever having a lip is engaged with the bar. The base is configured to engage said pivot lever to define a fulcrum. A retainer engaged with said pivot lever. A keeper secures the retainer to the base so that the retainer restricts pivoting of the pivot lever about the fulcrum thereby securing the bar to the base. The keeper is operable to release the retainer to permit rotation of the pivot lever about the fulcrum to release the bar from the base, thereby releasing the objects from being connected together.

Abstract: An expansible chamber device includes a braking system with a set of cam surfaces on the piston assemblies and a set of movable members adapted to alternately engage first and second sets of cam surfaces to stop the rotation of first piston assembly while permitting second piston assembly to rotate freely. A pair of elongate pivotable members engage the piston assemblies on one end and engage a slidable member having an adjustable length on the other end. The slidable member and the pivotable members alternate between first and second positions in response to engagement with ramp and stop surfaces provided on the piston assemblies. The rotating piston synchronizing system includes a set of biasing springs to urge the pivotable members into a suitable position to permit the device to be started from an at rest condition. The adjustable length slidable member enables a variable compression ratio.

Abstract: An expansible chamber device includes a rotating piston braking system and a rotating piston synchronizing system. The rotating piston braking system controls the motion of the expansible chamber device piston assemblies to cause intermittent rotation of the piston assemblies in the same direction during recurrent periods of rotation, with each of the piston assemblies being stopped between the periods of rotation. The braking system includes a set of cam surfaces on the piston assemblies and a set of movable members adapted to alternately engage the first and second set of cam surfaces to stop the rotation of first piston assembly while permitting second piston assembly to rotate freely. A pair of elongate pivotable members engage the piston assemblies on one end and engage a slidable member having an adjustable length on the other end.

Abstract: An axial flow turbine having one or more turbine wheels functioning both as the compressor and the turbine sections. Fluid flow is redirected over the compressor section to effect multiple stages of compression.
