  • Absorbent foam materials for aqueous fluids made from high internal phase emulsions having very high water-to-oil ratios
    Patent number: 5741581
    Abstract: Low density collapsed absorbent foams materials that, upon contact with aqueous fluids, in particular urine, can expand and absorb these fluids. These low density foams typically have an expanded thickness from about 6 to about 10 times the thickness of the foams in their collapsed state. These low density foams are made by polymerizing high internal phase emulsions (HIPEs) where the volume to weight ratio of the water phase to the oil phase is in the range of from about 55:1 to about 100:1.
    Type: Grant
    Filed: May 28, 1996
    Date of Patent: April 21, 1998
    Assignee: The Procter & Gamble Company
    Inventors: Thomas Allen DesMarais, Keith Joseph Stone, John Collins Dyer, Bryn Hird, Stephen Allen Goldman, Paul Seiden
  • Process for making thin-wet absorbent foam materials for aqueous body fluids
    Patent number: 5652194
    Abstract: Relatively thin, collapsed, i.e. unexpanded, polymeric foam materials that, upon contact with aqueous body fluids, expand and absorb such fluids, are disclosed. A process for consistently obtaining such relatively thin, collapsed polymeric foam materials by polymerizing a specific type of water-in-oil emulsion, commonly known as High Internal Phase Emulsions or "HIPE", is also disclosed.
    Type: Grant

  • Toilet flushing assembly
    Patent number: 4115881
    Abstract: An improved toilet flushing assembly is provided of the type which includes a water tank, a water discharge pipe disposed at least partially within the tank, and which has an opening at the upper end thereof, defining a primary flush valve seat, a flush valve ball communicative with the flush valve seat, means for moving the flush valve ball between an open and closed position relative to the primary flush valve seat, and a generally upstanding overflow pipe disposed within the tank and having a lower open end which communicates with the discharge pipe. The improved assembly provides an overflow pipe having an opening therein disposed at a level above the primary valve seat, which opening defines a secondary flush valve seat.
