Abstract: Orthopaedic wires, cables, and methods of making them are based on the discovery that, in clinical orthopaedic applications, material toughness and fatigue strength are as important or more important than ultimate tensile strength. The wires and cables of the invention have a tensile strength lower than 280 ksi, but higher than 175 ksi. The presently preferred wires and cables have a tensile strength of 210-240 ksi. The fatigue strength of the wires and cables of the invention is between six and ten times that of other high strength cables used in orthopaedic applications. One method of making the wires and cables includes annealing high tensile strength wire or cable to reduce its tensile strength and thereby increase its fatigue strength. Another method is to cold work fully annealed wire or cable to the extent of decreasing its cross section by approximately 18%.

Therefore, a repair cost, which must be paid by a vehicle owner, is reduced and an increase in the number of parts of the front end structure and an increase in the cost of assembling are suppressed even though gap &dgr; between the panel body 450 and the heat exchanger 21 is tightly closed so that a decrease in the heat radiating capacity (heat exchange capacity) of the heat exchanger 21 can be prevented.

Abstract: A process which allows elastomeric materials of different colors, durometers and/or other material characteristics to chemically bond to one another so as to eliminate any possibility of delamination. Latex-based liquid elastomer solutions having different material characteristics are applied sequentially to a heated mold to form a series of layers making up the article, with rapid partial curing taking place between each application; the partial curing forms a skin coat over each layer which prevents intermixing of the different solutions, but which still permits a chemical bond to form during full curing of the materials. The process applies equally to dip (immersion) molded and flat molded goods. An example of the invention as it relates to flat-molded goods is an athletic shoe sole, and an example as it relates to dip-molded goods is a resilient, one piece watersports boot which can be fitted over a human foot without a zipper.

Abstract: A method for laser marking one or more colors on a plastic substrate is disclosed. A polymeric blend or mixture comprising two or more polymeric systems is utilized to produce a molded component. The various polymeric systems are heated to form a polymeric blend or mixture that is in a molten flowable state.

While molding, the polymeric mixture separates according to the different densities of the polymers; with the lightest density polymers migrating toward the inner surface of the mold and the heavier density polymers centralizing within the interior of the mold. The lightest density polymer forms the outer surface of the molded product, which may essentially constitute an outer layer coating disposed around the other polymeric systems. Upon removal of the cured layered product, the skin layer is then preferably ablated using a laser to expose the polymers of desired color beneath the outer layer.
