Abstract: A method for the restoration of radial cord vehicular tires having damaged cords. A portion of the inner surface of the tire casing is removed over a region including at least the damaged area to a depth sufficient to remove all damaged radial cords. This removal region includes up to, and across, both bead portions of the casing. A patch unit having a conforming outline to that of the trough created by the removal is inserted into the trough and is bonded therein. This patch unit extends in the trough across the bead portions. The patch unit contains reinforcing cords to replace those that are removed. Preferably, the body of the patch unit is formed of uncured rubber which is cured in place in the casing so as to become permanently bonded to the casing. Cosmetic repair of the external surface can be accomplished by removing damaged material and thereafter filling the region, preferably with uncured rubber that is cured in place.

Abstract: Apparatus and method for applying a surgical staple which experiences some spring back following deformation. The invention enables the surgical staple to assume a rectangular shape with the tips thereof positioned together after the staple is closed. Specifically, the staple is deformed to overlap the tips so that release of deforming pressure results in tip-to-tip contact upon spring back. The invention addresses problems relating to skin being interposed between the spaced tips when a staple is closed. Also, as a result of the square-cornered rectangular shape of the closed staple, the problem of rotation of the staple after it is applied to the tissue is impeded. Preferably, the staple is heat recoverable having an open-shape memory configuration.
