An adjustment tool for adjusting a height of an upper bar of a gymnastics uneven bars apparatus. The adjustment tool is comprised of a shaft having a handle at one end and a horizontally-facing hook at an opposed end. In another embodiment, the hook faces upwards. The hook is sized and shaped to receive the upper bar, and is formed with a pair of outwardly flaring lips to allow the hook to be guided onto the bar without causing damage thereto. The handle is typically formed into a hook resembling that of a cane. A shaft length in an adjustable embodiment is comprised of two or more telescoping members mating with one another to establish and maintain desired shaft length.

Disclosed in some embodiments is a chamber component (such as an end effector body) coated with an ultrathin electrically-dissipative material to provide a dissipative path from the coating to the ground. The coating may be deposited via a chemical precursor deposition to provide a uniform, conformal, and porosity free coating in a cost effective manner. In an embodiment wherein the chamber component comprises an end effector body, the end effector body may further comprise replaceable contact pads for supporting a substrate and the contact surface of the contact pads head may also be coated with an electrically-dissipative material.

The invention relates to a device for holding and releasing an object, comprising a main body comprising a housing to at least partially accommodate said object and an opening to enable at least a portion of the object to be removed, a lid that can be moved from a closed position preventing access to said opening and an open position enabling access to said opening, and a stop mechanism designed such that it can be moved to different positions relative to the main body towards the opening of said main body, but blocked in the other direction, to enable the stop mechanism to be brought into contact with or close to the object while preventing any recoil of the stop mechanism. The invention also relates to a corresponding production method and release methods.

A system and method for hitching, using a swivel pin, a tractor with a drawbar and a towable implement comprise a handheld tool for inserting the swivel pin through a pin-receiving portion of the drawbar and a hitch tongue of the implement when arranged in an aligned coupling configuration. The handheld tool has an upper end configured for gripping by a user and a lower end configured to removably receive the swivel pin. Furthermore, the handheld tool is configured to extend from the operator cab of the tractor to the pin-receiving portion of the drawbar of the tractor so that the handheld tool is usable by the operator to hitch the tractor and the implement with the swivel pin without leaving the operator cab. A novel swivel pin with arms for mating engagement with a receptacle in the lower end of the tool enables the pin to be rotationally releasably secured therein.

A pickup bed tool assembly includes a handle which has a first portion that slidably engages a second portion such that the handle has a telescopically adjustable length. A push bar is pivotally coupled to the handle for pushing cargo into a pickup bed. The push bar is positionable in a deployed position or a stored position. A locking unit is movably coupled to the handle. The locking unit releasably engages the push bar to retain the push bar in either the stored position or the deployed position. The locking unit is actuatable to disengage the push bar thereby facilitating the push bar to freely pivot on the handle. A hook is coupled to the handle to grapple cargo in the pickup bed for pulling the cargo out of the pickup bed.

A vacuum gripper for gripping an object surface using vacuum suction is configured to be portable or operated by a hoist. Battery conservation measures are included to provide a long term vacuum generation capability, together with manually rechargeable mechanism. A manually-operated vacuum pump is also integrated to the vacuum gripper as a safeguard for the battery-operated vacuum pump failure. The vacuum gripper includes an elastic deformable vacuum seal for gripping objects with irregular surfaces, together with press rods or pin array configured to assist the vacuum seal in filling any gaps between the vacuum seal and the object surface.
