  • Patent number: 6946434
    Abstract: A non-toxic, non-hazardous, environmentally safe composition provides an effective, fast acting cleaning solution for removal of tar, oils, asphalt and other bituminous materials from industrial equipment surfaces. The composition is a mixture of a carrier monocyclic monoterpene and a nonionic surfactant such as an alkylphenol ethoxylate. The mixture is applied directly to surfaces to be cleaned, and rinsed with water in the absence of mechanical intervention.

  • Patent number: 4029101
    Abstract: An absorbent article for the perineum comprising, an elongated absorbent pad assembly having a front surface for facing the perineum, a back surface, and separable side portions adjacent the front surface of the pad assembly. The side portions define a longitudinally extending channel adjacent the lateral mid-point of the pad assembly, such that the side portions separate during use to expose an increased area of the pad assembly.
