摘要:
A rotorcraft rotor with hinged blades, includes: a hub; a plurality of blades hinged to flap relative to the hub; bottom abutments of the hub, and bottom abutments of the blades suitable for co-operating with the bottom abutments of the hub; and top abutments of the hub, and top abutments of the blades suitable for co-operating with the top abutments of the hub; the top abutments of the hub being movable between a deployed position in which they extend facing the top abutments of the blades, and a retracted position in which they are offset angularly away from the top abutments of the blades. The rotor also includes elements for locking the top abutments of the hub in the deployed position, and inertial means for releasing the top abutments of the hub and for deactivating the locking means.

The invention relates to novel cosmetic or dermatological compositions, characterized in that they comprise, in a cosmetically acceptable support, at least one solution or one emulsion of at least one multiblock polycondensate whose chain consists of the repetition of at least one polysiloxane block and of at least one polyurethane and/or polyurea block; the said polyurethane and/or polyurea block also including ionizable groups and the said polycondensate being dissolved in an aqueous, organic or aqueous-organic solvent system.These compositions may be used in particular in the cosmetic field of hair care, make-up or skincare.
摘要:
The present invention relates to an electromechanical motor (M) provided with an actuator (A) having an outer casing (30-30′-30″) surrounding a stator (20-20′) possessing a coil (24). The rotor (10) is also disposed inside the stator (20-20′). The invention is remarkable in that the actuator has two distinct and independent outlets (S1, S2) capable respectively of actuating, one after the other, first and second transmissions (C1, C2).
摘要:
Use of a composition containing at least one hydrophobic film-forming polymer and at least one thermal transition agent, in a physiologically acceptable medium, to obtain a film, wherein the composition is applied to a keratinous material, and the film may be removable with hot water. The at least one thermal transition agent being capable of undergoing a transition at a transition temperature Tt chosen within a temperature range of from 25° C. to 80° C., and being not water soluble in water maintained at a temperature below the transition temperature Tt, wherein the at least one hydrophobic film-forming polymer and at least one thermal transition agent are the same or different. The invention also relates to a composition containing, in a physiologically acceptable medium, at least 5% by weight, relative to the total weight of the composition, of at least one first hydrophobic film-forming polymer, and at least one thermal transition agent which is capable of undergoing a change of state within a transition temperature range of from 25° C. to 80° C., and being not water soluble in water maintained at a temperature below the transition temperature. The composition makes it possible to obtain a film which may be resistant to cold water and removable with hot water.
摘要:
The invention features a composition for treating keratin materials in particular human hair, containing in a cosmetically and dermatologically acceptable aqueous medium at least: a) a polyampholyte polymer comprising in the chain or in a lateral position relative to the chain, equimolar or practically equimolar amounts of negative charges and positive charges; the said polymer being water-insoluble at a concentration of 0.1% by weight or above and at 20° C.; b) a non-volatile, water-insoluble organopolysiloxyne of a viscosity higher than 3.10−5 m2/s (300 centistokes).
摘要:
The present application relates to hair-care compositions comprising aqueous polymer dispersions as film-forming agent. These polymers are obtained by free-radical polymerization of a radical monomer in the interior and/or partially at the surface of already existing polymer particles of polyester type.
摘要:
A cosmetic composition for application to the nail, comprising an aqueous dispersion of polymers and a plasticizer. The composition may be used as a varnish or a base layer for a traditional varnish, and/or as a treatment base for the nail.
摘要:
An aqueous cosmetic composition for fixing hair is an aqueous particulate dispersion. The dispersion includes particles of a film-forming polymer containing carboxylic acid functions neutralized to a degree of neutralization from between 10 and 80 percent using a non-volatile monobasic agent. The particles have an average diameter of between 10 and 300 nm. The aqueous dispersion also includes at least one plasticizing agent. The composition may be used as an aerosol lacquer, a fixing or setting lotion or a styling mousse.
摘要:
A copolymer produced by the copolymerization of a monomer mixture comprising at least 30 weight percent of at least one organic ethylenically unsaturated carboxylic acid, at least 30 weight percent of at least one N-alkyl acrylamide the alkyl group of which contains 8 to 30 carbon atoms in the alkyl chain and 0 to 40 weight percent of at least one hydrophilic unsaturated monomer as well as a corresponding copolymer the carboxylic groups of which are completely or partially salified. The preparation and the use of the copolymer as a thickening agent in compositions having a high amount of a surfactant such as a shampoo are also disclosed.
摘要:
