Abstract: An internal combustion engine utilizing a disk-shaped crankshaft operatively connected with respect to at least one pair of opposed pistons. Each piston of each pair is fixedly secured with respect to a shaft extending therebetween. With two pairs of pistons they are arranged at right angles with respect to one another such that each piston fires controlled by a timing device to maintain the rotary crankshaft. The crankshaft can include a gear device or a friction surface device about the external periphery thereof to facilitate distribution of power therefrom. The crankshaft defines an aperture therein within which a crank pin is positioned with an offset connecting arm extending in each opposite direction. The offset connecting arm extends into a bore within which is positioned the rod extending to each pair of pistons. The path of movement of the crank pin is circular to receive driving force from the pistons at selectively timed intervals.

Abstract: A flow control apparatus for regulating fluid flow through a plurality of tubular conduits which includes a housing and a pivotable control wheel capable of pivotal movement about the central axis thereof through a plurality of discrete positions defined peripherally therearound. The control wheel includes a cam profile edge circumferentially therearound adapted to abut a rocker member. The rocker member is movable between an initial flow position allowing flow through one tubular conduit while preventing flow through another and a final flow position preventing flow through the former tubular conduit and allowing flow through the latter tubular conduit. The rocker includes a first arm carrying a cam follower adapted to follow the cam profile edge to hold the rocker in the initial flow position and being responsive to movement into the cam slot means of the cam profile edge to facilitate movement of the rocker to the final flow position.

Abstract: A support for a grinding wheel or other rotary element used for conditioning workpieces, has the wheel arbor supported upon vertically shiftable support members, so that the distance between the lowermost, work engaging area of the wheel can be adjusted in respect to an underlying platen. In one form, slide blocks carry rotary idlers in tangential contact with diametrically opposite areas of the wheel, to sense wear of the wheel's periphery. As the wheel wears, the slide blocks gravitate to lower positions, to cause the wheel to be vertically adjusted downwardly to an extent that will maintain the distance between the bottom of the grinding wheel and the platen at a constant value. In a second form, an idler actuates an assemblage of links and levers that include the support members, to effect the downward vertical adjustment of the wheel.
