Peter W. Williams has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: Gloves, especially those of the type worn by surgeons, and fabricated from elastomeric materials have a hand conducting surface comprising an ionic polyurethane to render the glove hypoallergenic. The surface modifying composition may comprise a blend of an ionic polyurethane and a second polymer, e.g. another polyurethane or an acrylic polymer wherein the particle size of the second polymer are greater than that of the base ionic polyurethane. The use of blends enables donning of the glove to be effected without the aid of donning powder such as starch or talc.
