    摘要: A mattress of plastic foam material for medical purposes. The foam material is polyvinylchloride foam which has been coated with polyvinylchloride to create a completely seamless surface. Thus, the material is made impenetrable to potentially infectious body fluids which might be deposited thereon. In addition, the method of forming the entirely seamless surface prevents the accumulation of pathogenic fluids in various crevices which would otherwise be present in other types of seamless structures.

    摘要: An outdoor floor covering comprised of two laminated sheets of flexible water-resistant materials. A top one of the sheets has a low-profile ribbed outer surface and is comprised of a material capable of retaining flexible properties at low temperatures well below freezing. The other sheet is a backing sheet formed of a closed cell material having a density which is much weaker than that of the top sheet so that the backing sheet is impermeable and deforms under the force of a small load exerted on the top sheet whereby any ice formed on the top sheet can be easily broken by the deformation of the top sheet caused by a person standing on the floor covering. The backing sheet also has a thickness which is at least three times that of the top sheet.
