Abstract: A method and apparatus for transferring a weight of chain link mesh fence and holding the fence in position while a single installer secures the fence. The apparatus includes a lever arm, at least one tip for engaging an intersection of chain link mesh, a pivot point between the lever arm and tip, a hook attached to the lever arm by a flexible tether or connector which allows the chain link mesh to remain in place once engaged. The installer first places the pivot point on the fence post and pivots the chain link mesh upward to the desired height. Then the installer attaches the hook to an intersection of fence so that the flexible tether is taut. Once done, the forces are balanced on each side of the pivot point of the apparatus and the installer can release the tool and work with both hands to install the fence.

Abstract: A fluid sealing mechanism suitable for use in valves. This mechanism is capable of self aligning to ensure precise and repeatable sealing of the valve inlet to outlet. Sealing is accomplished by a plurality of standoffs on one surface which engage a plurality of corresponding grooves on another surface. Each standoff is independently adjustable in its height dimension in order to allow precise field adjustability of the sealing surfaces. This mechanism is suitable for use in pressure relief operations.
