Abstract: Motifs and patterns are generated by computer and printed on fabric, paper or plastic materials in continuous non-repeating patterns. The data is produced automatically by a random math algorithm, so that each of the printed patterns is similar, but not identical. The layout is arranged in a random manner, so that every part of the print is unique and exclusive. The size, color, motifs as well as the level of similarity or variety of the motifs and any other parameter essential to the design are all managed by the software.

Abstract: An ionomer and a process for forming the ionomer such that the ionomer has (1) low equivalent weight (below 950, preferably between 625 and 850, and most preferably between 675 and 800) and (2) high conductivity (greater than 0.13 S/cm). In another embodiment, the invention is an ionomer having (1) low equivalent weight (below 950, preferably between 625 and 850, and most preferably between 675 and 800) and (2) acceptably low hydration (less than about 120 weight percent). These ionomers are capable of being processed into thin film and are extremely well-suited for low humidity or high temperature fuel cell applications.

Abstract: An improved elastomeric material is described comprising an essentially noncross-linkable amorphous copolymer of tetrafluoroethylene (TFE) and perfluoromethyl vinyl ether (PMVE) which is both a thermoplastic and exhibits exceptional mechanical properties. This material is particularly suitable for use in ultra-clean environments, and particularly for use in an implantable device, since it does not contain contaminants that previous thermoset TFE/PMVE copolymers have required. Among the improved properties of the present invention are excellent biocompatibility, high matrix tensile strength, high clarity, high abrasion resistance, high purity, adequate elasticity, and ease of processing due to the thermoplastic, and noncross-linkable structure of the copolymer. The material of the present invention is also a high strength bonding agent particularly suited for bonding porous PTFE to itself or to other porous substances at room or elevated temperatures.

Abstract: An ionomer and a process for forming the ionomer such that the ionomer has (1) low equivalent weight; below 950, preferably between 625 and 850, and most preferably between about 700 and about 800; and (2) high conductivity, (greater than 0.15 S/cm). In an alternative embodiment, the ionomer has (1) low equivalent weight; below 950, preferably between 625 and 850, and most preferably between about 700 and about 800; and (2) acceptably low hydration, (less than about 75 weight percent). These ionomers are adapted to be processed into thin films that have acceptable physical stability. They are thus extremely well-suited for low humidity or high temperature fuel cell applications.
