Abstract: Infectious wastes from hospitals or other sources are sterilized in a chamber which is pivotable between a waste loading orientation, a sterilizing orientation and a waste dumping orientation. The chamber is attached to a framework by first and second pairs of pivot arms which are coupled to the sides of the chamber at spaced apart locations.

Abstract: This invention discloses weatherable elastomeric and thermoplastic composite polymer films incorporating organometallic complexes for protection of exterior surfaces against the growth of dark colored algae. The process involves the surface reaction of water soluble polyvalent metallic salts with surfactants at reduced surface tension in the presence of film forming emulsion polymers. The lipophilic organometallic reaction products thus formed are encapsulated by polymer films with demonstrated exterior weathering durability in roof mastics and architectural coatings. By virtue of their vapor transmission, adhesion and elastic properties, the composite polymer films incorporating compatible algicidal organometallics extend both the life and appearance of exterior substrates.
