  • Patent number: 6638881
    Abstract: An improved dental adhesive device to hold prosthetic devices in the human mouth is made as a laminate of webs which are bonded together by deforming a film of thermoplastic ethylene oxide polymer and having an external adhesive coating on the laminate. The dental adhesive is produced by continuously applying thermoplastic ethylene oxide polymer between moving webs of cellulose acetate fibers, applying additional thermoplastic ethylene oxide polymer to the external surface of the webs, and then passing said webs in superimposed relationship between a pair of dry heated calender rolls for thermoplastically bonding said webs into a unitary structure. A dry water-activated adhesive material, such as sodium alginate, may be employed with the thermoplastic ethylene oxide polymer by being dissolved or dispersed in the polymer. Synthetic fibers are applied to the webs so as to extend transversely through the webs.

  • Patent number: 5197208
    Abstract: An improved foot odor adsorbent is described having about 2.5% by weight of zinc oxide impregnated onto finely divided activated charcoal. Data is presented comparing the odor-reducing ability of the improved charcoal to conventional activated charcoal, zinc oxide powder, and standard latex foam that has been vulcanized with zinc oxide. Data is also presented showing the comparative odor-reducing ability of latex foam which incorporates various amounts of the improved activated charcoal and standard foam incorporating conventional activated charcoal.

  • Patent number: 4960077
    Abstract: An animal collar for controlling fleas and ticks which is formed as an elongated strip with fasteners at the ends thereof. The strip is a plastic material with an effective amount of pesticide dispersed therethrough and has a substantial cross section with a breaking strength such that the strip cannot be broken should the animal hang by the collar. The strip has at least one break point of greatly reduced cross section to provide for a fracture of the plastic strip. The fracture strength at the break point is determined by a dropped weight of about 60 percent of the weight that would cause fracture in straight gently applied tension. The collar is described as having two break points, each positioned opposite each other when the collar is fastened around the neck of the animal.

  • Patent number: 4632880
    Abstract: A new dental adhesive device to hold and cushion prosthetic devices in the human mouth is made as a laminate of webs which are bonded together by thermoplastic ethylene oxide polymer. The dental adhesive exemplified is produced by continuously applying thermoplastic ethylene oxide polymer between moving webs of cellulose acetate fibers, and thence passing said webs in superimposed relationship between a pair of dry heated calendar rolls for thermoplastically bonding said web into a unitary structure. A dry water-activated adhesive material such as sodium alginate may be admixed with the thermoplastic ethylene oxide polymer and applied to the moving webs before passing between the calendar rolls. It is also contemplated that the synthetic fibers be applied to the webs so as to extend transversely through the webs with the free ends of the fibers from each web being entangled so as to be mechanically interlocked.
