  • Patent number: 5405685
    Abstract: Papermachine clothing for use in the forming, pressing or drying sections of a papermachine including fibres of polyethylene naphthalate polymer which provides excellent hydrolysis and heat resistance as well as good mechanical properties such as tensile strength, tenacity, elongation and flexibility.
    Type: Grant
    Filed: May 18, 1994
    Date of Patent: April 11, 1995
    Assignee: Scapa Group PLC
    Inventor: Sanjay R. Patel
  • Patent number: 5151462
    Abstract: This invention relates to flame retardant blends of polysulfone, with polyalkylene phthalate. The present blends are flame retardant, even at thin part thickness.
    Type: Grant
    Filed: September 30, 1991
    Date of Patent: September 29, 1992
    Assignee: Amoco Corporation
    Inventors: Mohammad J. El-Hibri, Gregory S. Jack, William E. Kelly, Sanjay R. Patel
  • Patent number: 4937269
    Abstract: Quadrol and homologs and analogs thereof have been found to stimulate macrophage activity in warm blooded animals. As a consequence, these compounds may be used to combat bacterial infection, remove degenerated tissue, and promote new tissue growth. Quadrol or a homolog or analog thereof may be applied topically, e.g., as the active agent in a wound dressing. The active compounds may be represented by the formula (I) ##STR1## wherein R.sub.1 and R.sub.2 are substituted alkyl (C.sub.2 -C.sub.6) in which the substituents include one or more hydroxyl groups attached to carbon atoms other than the alpha carbon atom, R.sub.3 and R.sub.4 are alkyl or substituted alkyl (C.sub.1 -C.sub.6), and n=2 to about 6. Preferably R.sub.1 through R.sub.4 are the same and are 2-hydroxyalkyl.
    Type: Grant
    Filed: October 14, 1988
    Date of Patent: June 26, 1990
    Assignee: University of Akron
    Inventors: Daniel J. Smith, Sanjay R. Patel, Edwin C. Rowland
  • Patent number: 4889530
    Abstract: Acrylate and methacrylate monoesters and diesters having the following formula (I) ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 are as defined in the specification, are disclosed. These monomers are polymerizable into hydrogen polymers which are extremely hydrophilic. These hydrogel polymers are useful in the preparation of wound dressings. These polymers form complexes with polyvalent metal ions such as Ca, Mg, Mn and Cu, and possess macrophage stimulating activity in addition to the useful properties possessed by other acrylate and methacrylate hydrogel polymers.
