Resume: The invention relates to an electrolyte-separating membrane comprising a carrier (21) made of a porous and permeable synthetic thermoplastic material that is larger than 0.8 mm in thickness and an active layer (22) made of a material able to induce insertion and deinsertion reactions for selective transfer of cations through the membrane (2), the active layer (22) being deposited on the carrier (21) and being hermetic. The material of the active layer may in particular be a molybdenum cluster chalcogenide. The invention aims to provide an electrolyte-separating membrane that is able to transfer cations selectively and that may be manufactured with large dimensions. The invention also relates to a cation transfer method employing this membrane and to a process for manufacturing said membrane, in particular by selective laser sintering of a powdered polymer.

Resume: Une paroi de séparation d'électrolytes comporte un support (21) constitué d'un matériau en matière synthétique thermoplastique poreux et perméable d'une épaisseur supérieure à 0,8 mm et une couche active (22) d'un matériau apte à développer des réactions d'intercalation et de désintercalation pour le transfert sélectif de cations à travers la paroi (2), la couche active (22) étant déposée sur le support (21) et étant étanche. Le matériau de la couche active peut être en particulier un chalcogénure à cluster de molybdène. L'invention vise à fournir une paroi de séparation d'électrolytes apte au transfert sélectif de cations et qui puisse être fabriquée avec de larges dimensions. L'invention concerne également un procédé de transfert de cations utilisant cette paroi et un procédé de fabrication de ladite paroi, en particulier par frittage laser sélectif d'un polymère en poudre.

Resume: The invention provides a dispenser device (10) for dispensing a liquid cosmetic, said device comprising: a first bottle (12) that is defined, in part, by a bottom wall, and that contains a first initial volume of liquid cosmetic that is under a volume of gas that presents a first initial pressure, the first bottle (12) including, in its top portion, a spray valve (18); a second bottle (14) that includes, in its top portion, a spray valve (22), and that contains a second initial volume of liquid that is under a second volume of gas that presents a second initial pressure; and first transfer means (24) for transferring the liquid from the first bottle (12) towards the second bottle (14);; said device being characterized in that the first transfer means (24) comprise a first portion that is secured to the first bottle (12) and that is disposed in the proximity of the bottom wall, and a second portion that is secured to the second bottle (14), the first and second portions sealing their respective bottles (12, 14) when they are uncoupled, and in that the coupling of the first portion with the second portion enables the liquid to flow between the first bottle (12) and the second bottle (14), in such a manner that, after coupling the two portions together, the first and second bottles (12, 14) present first and second pressures that tend towards equilibrium by the liquid flowing from the first bottle (12) towards the second bottle (14).
