Abstract: A dump body for a dump trailer or a dump truck comprises modular components of tempered aluminum alloy joined together with mechanical fasteners to form modular subassemblies. Welding or other high-temperature joining processes are not required for fabrication of the dump body, and thus the full strength of the tempered aluminum alloy is retained. Methods for assembly of the modular components to form the modular subassemblies and for assembly of the modular subassemblies to form the dump body using mechanical fasteners are provided in addition to designs for modular components and modular subassemblies.

Abstract: An adjustable length device for grasping and manipulation of objects comprising a head region with opposing jaws joined to a handle region via a telescoping tube region. The tube region comprises a toothed rod connected to the jaws and a cable connected at one end to a trigger in the handle region and at the other end via a lever to a toothed rod locking mechanism (TRLM). The lever comprises one or more teeth that can mate with those of the toothed rod. Squeezing the trigger causes the lever in the TRLM to engage with the toothed rod and releasing the trigger causes the lever to disengage.

Abstract: A releasable hook assembly for use on a trapeze-type harness worn in the sport of sailboarding. A cord or line from the boom passes through the hook to reduce strain on the sailor's arms. The hook extends outward from a base plate which is supported over the sailor's chest by the harness, and is pivoted to swing outward to release the boom line. A latching engagement of the base portion of the hook to a hole in the base plate prevents such swinging or rotation until the line tension becomes great enough to overcome the force of a leaf spring to disengage the latch. The tension required is adjustable.

Abstract: An anti-theft tether in the form of a steel cable with a novel clip on one or both ends which fits the edge of a car door or window, and cannot be readily removed when the door or window is closed. The outer part of the tether is run through or around an object to be carried on the top of the car, such as a sailboard, a surfboard, or skis. One form of clip is made of thin, hard sheet metal, such as steel, and fits over the edge of the window glass. Another form of clip is flexible, preferably in the form of a short length of flat steel wire braid with an enlargement on one end. This is inserted between the car door and the door jamb, and the door closed and locked.
