Abstract: A method and apparatus for installing an elastomeric handgrip on an article. The handgrip is initially stretched over a hollow core consisting of one or more sections that can be removed from within the handgrip using slight tension. The proximal end of the assembly is placed over the article with the distal end of the handgrip aligned with the desired position, in some cases a positioning member being used to ensure proper alignment. The core is removed by tensioning the distal end, permitting the tubular handgrip to contract progressively starting from the distal end. In one embodiment, the core is a thin flat strip wound spirally and connected along abutting edges to form a helical tear line. The free end of the strip passes longitudinally through the bore from the distal to proximal end. Tension on the free end breaks the leading edge of the tear line, causing the strip to unwind and sequentially collapse each looped segment due to the force exerted by the handgrip.

Abstract: A method of forming thin metal sections of reactive metals which prevents high-temperature accelerated corrosion during hot working. The reactive metal section is placed in a non-reactive metal frame. Two non-reactive metal sections are machined to form depressions in which a release agent is deposited. The framed reactive metal section is interleaved between the two non-reactive metal sections such that the release agent is interposed between the principal surfaces of the reactive metal section and the non-reactive metal sections. The assembly is then clampled and welded together along the perimeter. The laminate structure is hot worked as by hot rolling to the desired gauge.
