Abstract: A fluid purifying module including a monolithic container, a pretreatment filter, and a selectively permeable membrane treatment cartridge, respectively housed in an external cylindrical space and an internal cylindrical space of the container, communicating with each other via one or more passages in the vicinity of one axial end of the container. The external space communicates at the same end as the opposite axial end with a first connector orifice for feeding fluid to be purified to the pretreatment filter, and the internal space communicates separately, at the same end as the aforementioned axial end, with a second connector orifice for evacuating from the module a flow of permeate (purified fluid) and with a third connector orifice for evacuating from the module a flow of retentate (residual fluid).

Abstract: A system comprising a fluid treatment assembly, means for feeding the assembly with fluid to be treated and receiving treated fluid, and a structure (12) on which the assembly is adapted to be removably mounted, to interengage complementary connectors thereof with each other, is characterized in that it includes cooperating functional surfaces (25) formed on the assembly and the structure (12) so that they can enter into mutual contact to immobilize the assembly against movement in translation and keep the connectors interengaged with each other when the assembly is mounted on the structure (12) and to allow the assembly to be released in order to remove it from the structure (12) by exerting on the assembly an action limited to tilting it relative to the structure (12) and guided by the connectors interengaged with each other.

Abstract: The module includes a monolithic container (30), pretreatment means (49) known in the art, and a selectively permeable membrane treatment cartridge known in the art, respectively housed in an external cylindrical space (36) and an internal cylindrical space (35) of the container, communicating with each other via one or more passages (37) in the vicinity of one axial end of the container (30), the external space (36) communicating at the same end as the opposite axial end with a first connector orifice (321) for feeding fluid to be purified to said means (49), and the internal space (35) communicating separately, at the same end as the aforementioned axial end, with a second connector orifice (322) for evacuating from the module (15) a flow of permeate (purified fluid) and with a third connector orifice (323) for evacuating from the module (15) a flow of retentate (residual fluid).

Abstract: Household appliance, in contact with an aqueous medium, having a water circuit at least partially traversing a compartment containing a disincrustant agent. The disincrustant agent is obtained by cross-linking or hardening of an organosilicic system having a disincrustant action.

Abstract: A steam iron soleplate divided into at least one steaming area having a plurality of steam outlets and at least one drying area having one or more grooves but free of steam outlets. The grooves are arranged in a network of furrows defining a pattern of raised lands.

Abstract: A steam generator with automatic supply having a level sensor arranged in a zone of a vessel located at a set threshold level, the sensor measuring the temperature and comparing it with a reference temperature, in order to establish whether a liquid reaches the threshold level, and an adjustment means acting in relation to the steam tapping operations so that the sensor temperature varies in relation to the level of liquid over a variation range, wherein the reference temperature remains within the variation range.

Abstract: A method and device for preventing the formation of scale in an electric appliance for producing steam, which appliance includes a reservoir for holding a quantity of water and a steam generation member for effecting a substantially instantaneous generation of steam; and a scale preventing device. Scale formation is prevented by heating water upstream of the reservoir to a temperature and for a time sufficient to precipitate minerals present in the water into a form which allows the precipitated minerals to be expelled from the appliance with steam generated by said steam generation member.

Abstract: A steam iron has a reservoir from which water is supplied to a vaporization chamber. A plurality of cartridges are placed within a housing of the iron and at least one cartridge contains a product other than a demineralizing product for the purpose of treating water or cloth to be ironed. A ramp is provided for bringing the water of the reservoir into contact with the treatment product. A duct beneath the cartridge conveys the water charged with the treatment product to a vaporization chamber. A plurality of steam discharge orifices in communication with the vaporization chamber distributes the treated water on the cloth to be ironed. The plurality of cartridges are arranged such that at least one is arranged in parallel or in series, or a combination of these, along a path in which water flows as it travels from the reservoir to the vaporization chamber.

Abstract: A steam iron including a vaporization chamber (2) connected by a water/steam supply device (8,11) to a flexible hose (9) extending from an external large-capacity reservoir(13). A device (5) regulates the water discharge that is also connected to the vaporization chamber (2), this discharge regulating device (5) being connected to an internal reservoir (4) incorporated in the iron (1).
