Abstract: A device for filtering of liquid and filling for a household electrical appliance including a main filtering device which is designed to filter a liquid; a main body including: a main tank having a pressing area that is deformable under the manual pressure by a user; a duct for emptying the main tank, the emptying duct designed to convey the filtered liquid from the main tank to a tank of a household electrical appliance when the deformable pressing area is deformed by the user. The main tank is situated downstream from the main filtering device, such as to receive and store the liquid filtered by said main filtering device.

Abstract: The invention relates to a system and a method for heat storage and recovery comprising a fixed bed (2) of storage particles. Fixed particle bed (2) comprises an obstacle (4), a flange for example, arranged on the periphery of fixed bed (2) of storage particles, and substantially perpendicular to the circulating flow (3) of said fluid. The invention also relates to a system and a method for energy storage and recovery using the system and the method for heat storage and recovery.

Abstract: The invention describes the use of compositions containing at least one thermoplastic polymer and an epoxy resin modified by at least one aromatic polyamine to coat surfaces, especially pipes through which oil is transported. The polymer compositions used contain at least one thermoplastic polymer which is preferably amorphous selected from the group formed by polysulphones, polyetherimides and polyphenylene esters and at least one epoxy resin modified by at least one aromatic polyamine containing at least two primary amine groups in its molecule. Different layers of polymers are deposited on different types of surface, more particularly as internal and external coatings for conduits. The invention also provides a surface coating comprising such compositions. Multi-layer coatings are also produced.
