Abstract: A splice joint is for joining first and second synchronous drive belt ends, of the belt type comprising a reinforcement material layer covering a base layer formed from a first thermoplastic material. The joint comprises a fused portion of the base layer of the first and second belt ends that define a splice region. At least one coating layer of thermoplastic material overlaps the reinforcement layer of the end portions in the splice region. The coating layer is comprised of a second elastomeric material intended to melt and penetrate into interstices of the reinforcement material layer while within the mold press. Migration of the base layer material through the reinforcement material layer to the pulley-engaging outer surface is thereby inhibited. The second elastomeric material composing the coating layer may be selected to provide desired frictional and wear characteristics.

Title: Wound dressings comprising hydrated hydrogels and enzymes
Inventor: DAVIS PAUL JAMES
IPC: A61F13/00
Filed: 2003-04-23
Granted: 2012-05-29
Abstract: A skin dressing, particularly a wound dressing, comprises oxidoreductase enzyme and, optionally, peroxidase enzyme, wherein the enzyme(s) are present in hydrated condition, e.g. being present in one or more hydrated hydrogels. The dressing is used by being located on the skin of a human or animal e.g. over a wound. The oxidoreductase enzyme catalyses a reaction that produces hydrogen peroxide from an appropriate substrate, the substrate either being naturally present in body fluids and/or being supplied separately and/or being incorporated into the dressing. The currently preferred oxidoreductase enzyme is glucose oxidase. The catalyses reaction of .beta.-D-glucose substrate to give hydrogen peroxide and gluconic acid. A mixture of oxidoreductase enzyme can undergo reaction (optionally catalysed by the peroxidase enzyme) to produce a variety of species including reactive oxygen intermediates that have antimicrobial properties and that can therefore assist in promoting wound healing.
