Abstract: A method for repairing a discrete damaged part of a strip bonded to an article surface includes applying a first removable masking member along and adjacent the damaged part of the strip and separated from the strip by a gap of at least 0.005″, and applying a second removable masking member to the outer surface of the strip. A repair adhesive, which can be cured at a curing temperature less than a higher temperature which can result in damage to properties of the article or a surface coating, is applied at and beneath an edge of the damaged part of the strip. Then the repair adhesive is cured at the curing temperature. Apparatus for bonding a strip to an end portion of the article includes a body having a channel there through defined, in part, by spaced apart support surfaces for article surfaces and positioned relative one to the other at a relative spatial position substantially coinciding with the relative spatial position of the article surfaces.

Abstract: The tape is free from any slack and separation even when it is applied and bonded to a metal joint portion while being bent. The tape, made of an unvulcanized material containing an unvulcanized rubber-base material, a vulcanization accelerator, an anti-oxidizing agent, a pigment and a bulk filler, is formed into an elongated shape having an upper and a lower surface and a predetermined thickness measured in a direction perpendicular to the lower surface or flat bottom surface 1. The upper surface forms a circularly-curved surface 2 in cross section. Since the tape is in an unvulcanized state, it is capable of being free bent when applied to the metal joint portion. After application of the tape to the metal joint portion, a paint is applied to the tape, which is followed by a heating process in which the tape is heated, and, therefore vulcanized.

Abstract: A method of repairing metal surfaces, in particular hydraulic cylinder interior walls and pistons, which are damaged by scoring, denting, grooving, etc. A catalytically hardened synthetic resin, preferably an epoxy, is mixed with a selected metal powder to form a mixture which, when hardened has a coefficient of thermal expansion substantially equal to that of the metal surface. A hardener is mixed with the filled resin and the damaged areas are filled with the mixture. The resin is cured, then dressed so that the damaged areas conform to adjacent undamaged surfaces. The repair area (and other surface areas, if desired) is then electroplated with a hoard, tough, wear-resistant metal, preferably by brush plating. The plated areas are then polished and the repaired article is ready for use.

Abstract: We control the cure temperature within ±15° F. (8° C.) for organic resin matrix composites with a thermal diffusion apparatus which contains a liquid fluid transfer medium to convey heat from an immersed resistance heater to the repair site. Uniform heating of the repair site occurs despite differences in the underlying structure of the repair site, such as the location of underlying spars or other structural features or variations in the skin thickness, because of natural convection within the heat transfer fluid. The fluid transfer medium preferably is a solid, at ambient temperature, but melts at a relatively low, elevated temperature below the cure temperature. We achieve uniform heating that is necessary for suitable repairs to temperatures of at least about 350° F. (177° C.) and simplify monitoring of the repair site temperatures because of the uniform heating we naturally achieve.

Abstract: The subject invention pertains to compositions comprising a rubber-like polymer and low boiling point alkanes which can be used to provide a flexible, durable, permanent repair for snags, holes, runs or ladders in hosiery such as pantyhose and nylon stockings. In a preferred embodiment, the rubber-like polymer is a gum-like residue obtained from drying commercial rubber cement adhesive. A composition comprising 2% weight to volume of this residue in an equal volume solvent system of pentane and hexane is applied to the snag and allowed to dry. When the repair is made while the stocking is being worn, a thin, transparent shield can be inserted between the stocking and the skin of the person wearing the stocking. The shield protects the skin from the composition yet does not adhere to the skin or stocking. The shield therefore can be easily removed after the composition is dry or can be left in place between the skin and the hosiery.

Abstract: Increasingly stringent environmental restrictions make it challenging to apply coatings (i.e., paint) by conventional processes like spray painting because of the volatile solvents and hazardous pigments. The environmental scrutiny is particularly focused upon conventional corrosion protection surface treatments, especially chromated primers and conversion coatings. We apply appliqu{acute over (e)}s to provide a vapor barrier over the substrate to provide corrosion protection. We can make curved appliqu{acute over (e)}s on a family of molds of different Gaussian curvature and thereby avoid making a “splash” mold of the surface of interest to create the appliqu{acute over (e)}s. Using curved appliqu{acute over (e)}s reduces ridges, creases, or gaps that sometimes otherwise occur with attempts to a cover a surface with complex curvature with flat (planar) appliqu{acute over (e)}s.
