Patent number: 6706781Abstract: 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.Type: GrantFiled: August 14, 2002Date of Patent: March 16, 2004Assignee: The Procter & Gamble CompanyInventors: Jayanth Rajaiah, Kimberly Ann Gilday-Weber, Lisa Catron Ernst, Thinh Nguyen Ha, John E.

Patent number: 6523409Abstract: 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.Type: GrantFiled: June 8, 2001Date of Patent: February 25, 2003Assignee: Brudis & Associates, Inc.Inventors: Tony Brudis, Seward Cross, Robert Milstead, Nguyen Ha
