  • Patent number: 4230108
    Abstract: A flexible esophageal tube is provided for insertion through the mouth, downward past the tracheal entrance and into the esophagus to a lower limit opposite the tracheal carina. Inflatable cuffs are respectively fixed, above and below the tracheal entrance, on the esophageal tube for sealing the tracheal entrance against leakage around the tube. A ventilating tube is sealed in the esophageal tube against the anterior wall of the upper part thereof with an open distal end projecting out of the esophageal tube and mouth and a closed distal end extending past the tracheal entrance. Perforations defined in the common anterior surface of both tubes between the cuffs admits anesthetics, introduced at the distal end of the ventilating tube, to pass into the tracheal entrance, trachea and lungs.

  • Patent number: 4196107
    Abstract: This invention relates to coating compositions which are "solid" prior to application, yet, which when applied to a substrate, flow and level in a manner similar to conventional coating compositions. The coating compositions of the invention comprise a gelled coating composition, capable of application and flow on a solid substrate comprising: (a) a water reducible polymer, (b) water, (c) an electrolyte, and (d) a colloidal gelling agent, gelable by interaction with the electrolyte, in an amount sufficient, when interacted with said electrolyte, to gel the composition to form a stable semisolid and to provide a composition reducible to a coating application viscosity upon the application of a relatively small shearing force at a relatively small shearing rate; which gelled coating composition, after being sheared to a coating application viscosity, does not recover substantial colloidal gelling agent contributed gel structure.
