The holder has an open end and resilient side walls for closely receiving the upper portion of a key cap. The closed end of the holder is at an angle to the direction of movement of the holder and is adapted to engage the upper surface of the key cap to more nearly align the cap with the key switch when the cap is pressed on the switch by the holder.

Abstract: The cover for the otherwise open cargo bed of a pickup truck includes a plurality of rectangular panels hinged together laterally of the cargo bed so as to fold forwardly in accordion fashion for storage as a compact stack at the forward end of the bed. The panels are thin whereby the stack has a low silhouette and does not obstruct the rear window of the cab. At least the sides of the cover are enclosed by an upstanding gasket which shields the cover from the vehicle's slip stream and crosswinds which would otherwise make it necessary to provide a tie-down for the cover when in cargo bay closure position.

Abstract: A track for a tracked vehicle has a pair of belts bridged by bars along the uter surfaces of the belts while along the inner surfaces thereof, along two mutually juxtaposed edges, the belts are unitarily formed with cleats cooperating with a roller of the vehicle to provide lateral guidance. Preferably the cleats along the two edges of the belts are disposed symmetrically with respect to a longitudinal median plane of the track.

Abstract: A closure control assembly for tensioning a flexible curtain over an opening in a truck trailer including a shaft with a vertical axis of rotation, bearing members rotatably connecting the shaft to the truck trailer, a driver connected to the shaft and a driven member connected to the curtain for engagement with the driver. The driver includes stepped projections for engagement with stepped surfaces on the driven member for sequential engagement of the driver and driven member upon rotation of the shaft by an operating member. A locking mechanism secured to the curtain engages the operating member to secure the curtain in the tensioned position.

Abstract: A multipurpose ball collector, ball storage and ball dispenser uses a wheel driven rotating shaft and fixed projections to positively collect balls, a wire cage to store balls and a folding handle with a folding cage door to conveniently allow withdrawing of the balls during practice. The folding handles are pivoted and attach to each other during collection to provide structural integrity. For dispensing, the handles and attached to the cage to form a structure which lifts the cage to within easy reach for the practicing player. Collection arms can also be provided to assist in ball collection or carrying the cage to a storage location.

Abstract: A chain link of a chain track is penetrated at its joints to adjacent chain links by bolts, for example connector bolts or hinge bolts. The chain links are connected in a positive and frictional manner. The chain link may be made of elastomeric material in which flexible, high tensile filaments are embedded. The filaments may be wound back and forth between the two joining locations and loop around the cross-sectional surfaces of the bolts (connector bolts or hinge bolts) located at the joining locations, in alternating directions. A chain track assembled from individual chain link elements may have individual chain link elements including a shear field support of one or more layers of readily bending steel foil, surrounded on both sides by elastomeric material. The layer or layers of steel foils are clamped at the two joint locations of adjacent chain link elements between a transverse web and a clamping bar, with the chain links connected to one another by threaded fasteners.

In a preferred embodiment, the gripping members are triangular and are arranged in spaced parallel row adjacent the first and second edges.

Abstract: A movable yoke-type lifting magnet device including a main core wound with a coil and at least one yoke magnetically coupled to the core. The movable mechanism of the yoke enables the yoke to freely follow the contour of a workpiece to be lifted. An auxiliary core may be provided between each said at least one yoke to provide a yoke-type lifting magnet device. The auxiliary core greatly increases the magnetic forces induced between the cores and the yoke. Combination of the magnetic coupling between the yokes and the core and the provision of the auxiliary core provides a movable yoke-type lifitng magnet device wherein the yoke can freely follow the contour of a workpiece and the magnetic forces between the cores and the yoke are greatly increased. Such a combination prevents the yoke from slipping relative to the cores and stable lifting is possible.

In a second embodiment the equalizer bar is connected to the housing by another coupling device including a trunnion member having a pair of similarly oriented pivot pins. In each instance the transversely oriented equalizer bar is arranged along the transversely oriented central axis of the drive wheel, which provides a very stable 3-point frame suspension that is also rugged and economical and has a minimal tendency to collect mud or debris on the upper surfaces thereof in use.

Abstract: The invention relates to a process for the separation of granulate materials, in extruded form of different lengths and of the same or different diameter. It is characterized by the use of a helicoidal vibrating elevator subjected to vibrations whose amplitude is chosen so as to cause on the threads of the spiral on the one hand the ascending flow of all the particles and on the other hand the recovery of the finest particles on the outer edge of the upper thread of the spiral and the largest particles on the inner edge of the upper thread of this spiral.
