Publication number: 20070279413Abstract: The invention relates to a method of generating a synthesized image of a hair, comprising the following steps: calculating the shape of the hair by applying a behavioral relationship determining the shape of the hair as a function of a physical parameter linked to a mechanical property of the hair, in particular the linear density; producing an image of the hair of shape that has been calculated in this way. The behavioral relationship may be given by the minimization of the following function: E = K L ? ? 0 1 ? [ 1 2 ? ( k ~ ? ( s ~ ) - ? ) 2 + 1 ? ? z ~ ? ( s ~ ) ] ? ? s ~ , where ?=Lk0 and ?=K/g?L3, and where L designates the length of the hair, k0 its spontaneous curvature, K its bending moment, ? its linear density and g the acceleration due to gravity, {tilde over (s)} the curvilinear abscissa relative to the length of the hair, {tilde over (k)} its local curvature relative to its length and {tilde over (z)} its height relative to its length.Type: ApplicationFiled: March 19, 2007Publication date: December 6, 2007Applicant: L'OREALInventors: Jean-Luc Leveque, Basile Audoly, Frederic Leroy, Bernard Querleux

Patent number: 6923953Abstract: The invention concerns a method for treating hair keratin fibers to provide them with new appropriate properties, comprising the following steps: reducing the sulphur bonds of hair keratin to generate only at the surface of the fibers at a depth less than 10 ?m. reactive sites and in fixing covalently on said reactive sites at least one active compound for providing the hair keratin fibers with new appropriate properties, said active compound containing at least a reactive function capable of reacting with said reactive sites formed at the keratin fiber surface. This method is applicable to the treatment of fibrous or non-fibrous keratin substances of human or animal origin.Type: GrantFiled: January 25, 2002Date of Patent: August 2, 2005Assignee: L'OrealInventors: Gérard Malle, Frédéric Leroy, Yolanda Duvault

Patent number: 5280795Abstract: According to the process for applying reshaping to hair by use of a hair-curler, the hair-curler (1) is arranged in such a way that the perimeter along which the lock of hair (M) is rolled increases by approx. 2 to 3% when its temperature rises to pass from a starting temperature to a higher temperature which nevertheless remains lower than a relatively low limit thus avoiding the burning of the hair and/or of the scalp; the longitudinal section of the curler is sufficient to withstand the stresses imposed by elongation of the lock of hair; the lock of hair is rolled around the curler at the starting temperature so that the hair is retained against the hair-curler; the curler is raised to the said higher temperature; the hair is thus subjected to elongation ensuring an increase in the life of the reshaping applied to the hair.Type: GrantFiled: April 27, 1992Date of Patent: January 25, 1994Assignee: L'OrealInventors: Jean-Luc Leveque, Frederic Leroy

Patent number: 5151015Abstract: The device for the compression of a gas comprises a motor (1), a piston (2) adapted to be displaced linearly in a pump body, transmission means (T) between the motor (1) and the piston (2) adapted to convert the rotary motion generated by the motor (1) into a reciprocating translatory motion by the piston (2). Speed varying means comprising a cam (12) are provided to impart a different speed to the piston (2) of the compressor according to the resistance opposing the motor (1) during one complete admission/compression cycle, so that the resisting torque is substantially constant and so that the motor (1) operates at its maximum torque and therefore at maximum efficiency. The section of the cam (12) is determined so as to ensure substantially isothermal compression of the gas.Type: GrantFiled: May 13, 1991Date of Patent: September 29, 1992Assignee: L'OrealInventors: Daniel Bauer, Frederic Leroy, Gerard Braque, Andre Charon
