Abstract: The present invention discloses a plastic processing roll, comprising a rigid inner cylinder covered at least partially by at least one flexible liner. Said flexible liner comprises a plurality of fluid ducts, each of which being connected to an inflow duct and being connected to an outflow duct. An elastic metal sleeve encases said flexible liner and is designed to be friction-locked by means of pressurizing the fluid ducts. Said flexible liner is formed by a plurality of longitudinal elements being arranged in parallel to each other, wherein each of said longitudinal elements houses at least one of said fluid ducts. Furthermore a plastic processing device and a method for producing double-sided structured plastic films is disclosed.

Abstract: Process for manufacturing a plastic fuel tank provided with at least one accessory (14) connected to the internal space of the tank via at least one orifice (12) in the wall (10) of the tank, the accessory including a projecting element (24) extending to the outside of the tank, the processing comprising the steps consisting in providing a film (22) that includes a peripheral region (28) and a border region (30) around an opening in the film, in placing the film on the wall of the tank and on the outer surface of the accessory in such a way that the projecting element passes through the film via the opening, in welding the film over its entire peripheral region to the wall of the tank, and in welding the film, over its entire border region, to the outer surface of the accessory.

Abstract: The present invention relates to a cosmetic process for caring for human skin, intended to moisturize it and/or to protect it against drying out, comprising the topical application to the skin of a composition containing at least one active agent that stimulates the expression of the matriptase MT/SP1. It also relates to the cosmetic use of such an active agent for moisturizing human skin and/or protecting it against drying out. It further relates to the use of such an active agent to manufacture a pharmaceutical composition intended to prevent and/or alleviate skin tautness, stinging and/or itching and/or lip chapping. The active agents are extracts of Ceratonia siliqua, Cananga odorata hook, Cedrelopsis grevei and Cistus ladaniferus L.

Abstract: The invention relates to a cosmetic skin care method, intended to prevent and/or treat at least one cutaneous sign of ageing, including topical application to the skin of a composition containing at least one botanical active ingredient which increases the production by keratinocytes of at least one growth factor chosen from bFGF and PDGF.

Abstract: The present invention relates to a cosmetic skin care method to prevent and/or treat at least one sign of skin ageing, comprising the topical application to the skin of a composition comprising at least one active ingredient selected from cassumunarin and/or an arylbutenoid and/or a botanical extract containing them, such as an extract from Zingiber cassumunar Roxb. It also pertains to an extract from Zingiber cassumunar Roxb, which is obtainable by extracting rhizomes thereof with at least one apolar solvent having a polarity index of less than 1, optionally mixed with at least one polar solvent having a polarity index of more than 3.5.

Abstract: In a fuel tank and a process for manufacturing the fuel tank, accessories emerging through the wall of the tank are covered by a flexible film of multilayer structure that includes a fuel barrier layer. The perimeter of the film is welded to the wall of the tank.

Abstract: System for closing off an opening in a plastic tank, formed from a sheet of multilayer plastic that includes a barrier layer, the said sheet being welded around the perimeter of the opening and provided with a peripheral region that is slimmed down so as to effectively restrict the permeation of gases and liquids into the layer located between the tank and the barrier layer. Method of closing of a tank by welding such a plate, comprising the welding of the slimmed-down peripheral part by the technique of laser or infrared radiation welding. Use of the method to close off a fuel tank for a motor vehicle.

Abstract: A system for fastening, by welding, a component having a portion with a conical surface profile to a motor vehicle fuel tank that includes an opening whose perimeter has a conical surface profile. The welding is carried out between at least one portion of the conical surface of the perimeter of the opening in the tank and at least one portion of the conical surface of the component.

Abstract: Process for manufacturing hollow plastic bodies, especially motor-vehicle fuel tanks, from an extruded parison of closed cross section, in which at least one cut is made in the parison which is then formed by moulding.

Abstract: Process for manufacturing a plastic fuel tank from two shells formed by molding, which are joined together, at least one shell being produced by compression-molding a portion of a plastic sheet between a mold and a punch and by the remaining portion of the sheet being blow-molded in the region not compression-molded.

Abstract: Fuel tank comprising a canister containing a composition capable of retaining fuel vapours and which is associated with an overfill prevention device also located inside the tank.

Abstract: Fuel system for a vehicle with a heat enigine, comprising a hollow body made of plastic, designed to contain or to transport fuel, and means of covering this hollow body by means of a rigid jacket surrounding the hollow body. The covering means form, with the surface of the hollow body, a confined space fitted with a device for flushing by means of air. The air which entrains any emitted vapours is purified before being discharged into the atmosphere or is mixed with the air blown out by the engine. The invention is applicable to a double jacket for a fuel tank made of plastic or to a fuel pipe fitted with a concentric channel.
