  • Patent number: 6719995
    Abstract: Systems for delivering cosmetic and therapeutic actives to the oral cavity employ a strip comprising a first layer of material, a second layer comprising polybutene with a molecular weight of about 300 to about 3000, and a cosmetic or therapeutic active included within the second layer. Therapeutic and cosmetic actives in compositions comprising polybutene inhibit or prevent gingivitis, caries, staining, fungi, bacteria and plaque build-up in the oral cavity by means of the delivery system.

  • Patent number: 6706781
    Abstract: The present invention relates to methods and compositions for reducing, inhibiting, and/or preventing, calculus, tartar, plaque, and/or microbes, in the oral cavity, comprising from about 15% to about 70% of an alkyl vinyl ether maleic copolymer or terpolymer denture adhesive component, an effective amount of a quaternary ammonium antimicrobial agent selected from the group consisting of cetylpyridinium chloride, domiphen bromide, and mixtures thereof, and a non-aqueous vehicle. A denture wearer in need thereof applies the composition to the oral cavity and/or the denture prosthesis and thereafter secures the denture to the oral cavity.

  • Patent number: 6523409
    Abstract: The advisory speed meter is used to determine the advisory speed for a highway curve or to provide data for use in determining the advisory speed for a highway curve. The meter determines and records the maximum lateral horizontal acceleration experienced by a vehicle and occupants while traversing a highway curve. The meter has been extensively tested on rural curves and on entrance and exit and connecting ramps between all types of highways. The process for determining an advisory speed for a curve is described. The advisory speed meter provides accurate, reproducible data for use in determining advisory speeds for highway curves.
