An automated parking system includes a multi-story tower having a central elevator shaft. The building is substantially circular in cross section and contains a plurality of parking stalls that radiate from the elevator shaft on each of the stories. An elevator mechanism elevates a turntable, rotatably mounted on the elevator mechanism for rotation about a substantially vertical axis, between the several floors of the building. A shuttle travels from the turntable to an entrance ramp on the ground level of the building, moves a vehicle to be parked from the entrance ramp to the turntable, whereupon the elevator and turntable cooperate to deposit the vehicle in a parking stall on one of the several floors. The elevator and turntable mechanism operate in reverse to carry the vehicle from a parking stall to an exit ramp on the ground floor of the building.

An athletic shoe sole has a heel section and a toe section bearing flange-shaped, turf-gripping members. The first gripping member is a generally downwardly and outwardly extending flange that runs around the entire periphery of the sole. The second gripping member is an ovoid-shaped, generally downwardly and outwardly extending toe flange positioned in the toe section of the sole and spaced inwardly from the portion of the peripheral flange on the toe section. The third gripping member is a heel flange extending downwardly and outwardly from the heel section of the shoe and spaced inwardly from the portion of the peripheral flange on the heel section. The rearward portion of the heel flange is arcuate and merges into two generally forwardly extending flange portions that flare outwardly and join with the peripheral flange adjacent the forward end of the heel section. All of the flanges are downwardly convergent and have a bottom edge. The bottom edge of the heel and toe section flanges extends downwardly from the sole a greater distance than does the bottom edge of the peripheral flange. Depending upon the playing surface on which the sole is to be used, additional ovoid-shaped toe section flanges can be positioned intermediate the first or inner toe section flange and the peripheral flange. Additional heel flanges positioned intermediate the first heel flange and the peripheral flange on the heel section of the sole can also be employed. The additional heel and toe section flanges are especially advantageous for use on synthetic playing surfaces.

A fluid actuated nail extractor includes a pair of jaws pivotally mounted on a reciprocable rod. An impact piston impacting a second rod coupled to the jaws closes the jaws about a nail embedded in a workpiece when the extractor is positioned adjacent the nail. Thereafter, a second piston actuates the reciprocable rod to extract the nail from the workpiece. Pressurized fluid, controlled by a plurality of poppet valves, drives the pistons through a predetermined sequence of operations. The entire sequence of operations is dependent upon the position of a safety valve that is actuated by a push rod having an end located adjacent the jaws. The push rod is actuated only when the nail extractor is positioned adjacent the workpiece, and hence actuating the safety trigger valve so that the operational sequence of the pistons can be initiated.

An expansible drive shaft tool mechanism is disclosed in which mutually cooperating parallel drive shafts carry tool elements that can be shifted into and locked by shaft expansion in any of selected positions along such drive shafts. Applied hydraulic pressure in a sealed chamber causes outward expansion of a flexible outer sleeve member on each such shaft to grip the tool elements. An inner sleeve member closely encircled by the outer sleeve member and joined in sealed relationship therewith at opposite end portions forms the radially thin elongated annular sealed chamber into which the pressurized hydraulic fluid is forced by the action of a plunger type hydraulic pressure source housed inside the inner sleeve member cavity. Actuation of the hydraulic pressure source plunger passing through a cylindrical fluid take-up chamber by longitudinal displacement is effected by means of a pneumatic piston energizable through a connecting line including a low pressure rotary seal or union. Hydraulic fluid that may leak past a primary seal along the plunger is taken up in the seal chamber which, of cylindrical form, incorporates a sliding piston or seal element contacting the plunger and cavity wall and urged by a return spring to exert pressure on such accumulating hydraulic fluid tending to return it to the hydraulic cylinder. Such seal chamber including the spring-returned seal element is thus available to take up leakage of hydraulic fluid seeping past the primary seal, whether caused by operating pressure or by thermal expansion of fluid in the system, and to urge the fluid back through a check valve when the pressure drops again.
