  • Device for superficially heating an adjacent body
    Patent number: 4028518
    Abstract: Device for superficially heating an adjacent body comprising a high frequency resonator means for producing an electromagnetic field inside said resonator at the resonant frequency of said resonator when said device is adjacent a surface to be heated, and means for conducting energy from said field to radiating means outside said resonator.
    Type: Grant
    Filed: June 13, 1975
    Date of Patent: June 7, 1977
    Assignee: L'Oreal
    Inventors: Georges Boudouris, Gregoire Kalopissis, Jean-Luc Leveque, Paul Roussopoulos
  • Cosmetic composition containing essentially homogeneous vinyl acetate/crotonic acid copolymer
    Patent number: 3984536
    Abstract: A cosmetic composition for use as a hair lacquer or hair-setting lotion contains an essentially homogeneous vinyl acetate/crotonic acid copolymer, the macromolecular chains of which contain essentially the same content of each of vinyl acetate and crotonic acid along the entire length thereof. The content of each of vinyl acetate and crotonic acid does not vary more than 2.5% by weight relative to the average content of each in essentially all of the macromolecular chains, along essentially the entire length of each of said chains.
    Type: Grant

    Date of Patent: October 5, 1976
    Assignee: L'Oreal
    Inventors: Andre Viout, Paul Roussopoulos, Christos Papantoniou
  • Method and apparatus for dissipating high frequency energy inside a material to be treated
    Patent number: 3980855
    Abstract: Method and apparatus for dissipating high frequency electromagnetic energy inside a material. The apparatus comprises a conductive jacket defining a resonant chamber, a coil inside said chamber connected to a coaxial cable supplied by a high frequency generator, the frequency of which is equal to the resonant frequency of the chamber. The impedance of the resonator and its contents is matched to that of the coaxial cable. Automatic means may be provided for altering the resonator impedance to compensate for changes in load impedance.
