Abstract: A system that secures an upper door of a UTV or other vehicle to the vehicle and enables the ready removal and storage of the upper door from the vehicle employs magnets. A first set of magnets is carried by the upper door. A second set of magnets, which is attracted to the first set of magnets, is carried directly or indirectly by the vehicle, such as by a filler panel secured to the vehicle. Methods of deploying and securing an upper door in place and at least partially removing the upper door are also disclosed.

Abstract: The present invention provides a method of producing high-strength and high-conductance copper and silver materials comprising the steps of combining a predetermined ratio of the copper with the silver to produce a composite material, and melt spinning the composite material to produce a ribbon of copper and silver. The ribbon of copper and silver is heated in a hydrogen atmosphere, and thereafter die pressed into a slug. The slug then is placed into a high-purity copper vessel and the vessel is sealed with an electron beam. The vessel and slug then are extruded into wire form using a cold hydrostatic extrusion process.
