Abstract: The invention concerns a network creation process for the provision of internet and/or television type data signals across the complete land surface, Linking through a digital wireless link at least one aircraft (300) with the earth station (200) on one hand, and on the other hand, with at least one means of emission and receipt, whether fixed or borne by at least one user (400), moving to an altitude lower than or equal to ten kilometers above the global land surface, and being equipped with one or several payloads powered by the energy of the aircraft (300) in such a way as to use emission and receipt relays for the provision of at least one type of signal on the global land surface. The said process is remarkable in that the power of signals (radiation) emitted by the payload is modulated to vary according to the altitude of the aircraft (300) and can thus vary from 0% on earth to 100% during cruising. The invention also concerns the payload and the aircraft that enable implementing the said process.

Abstract: The invention relates to a cleaning device, in which said device is supplied with liquid. The device is characterised in that it comprises a mobile chassis supporting a plurality of functional subassemblies necessary for the production of a hot liquid in a condensing gas boiler with sealed combustion chamber. The invention can be used to clean the pipes in an aircraft.

Abstract: A device for communicating and monitoring railway tracks includes a plurality of communicating and monitoring terminals arranged along the tracks. Each of the terminals includes an image-capturing module, a wireless communicating module that allows for communication between the terminals and with a train, and a module for storing electrical power continuously supplying the image-capturing module and the communicating module. Each terminal also includes a power-generating module for supplying the module for storing electrical power. The power generating module recovers energy from the air displaced by the train running over the railway track. The device permits permanent monitoring by capturing images and makes permanent wireless connections available to the trains.

Abstract: The invention relates to a metering device (D) for metering a reagent by dissolution in a liquid flow, characterized in that it comprises a plurality of parts: —a fixed base (200) grouping together said enclosure and a liquid inlet, means for bringing the liquid into contact with the reagent roller (G) and liquid outlet means, —one or more cartridges (300) forming a separate detachable volume grouping together said reagent magazine, means for forming at least one liquid jet directed substantially radially towards the roller (G) to be dissolved, and means for supporting the roller (G), said cartridge (300) coming to be associated with said base (200) which is preformed with at least one area for receiving said cartridge (300) for the purpose of dissolving the reagent.

Abstract: The invention relates to a device for cleaning the pipes of the drinking water circuit of an aircraft, in which the device is independent of the aircraft and is connected to the circuit intermittently and supplied with liquid. The device is characterized in that it comprises a mobile chassis supporting a plurality of functional sub-assemblies required to produce a hot liquid, including a closed-furnace gas condensing boiler. The invention can be used to clean the pipes of aircraft.

Abstract: The invention relates to a method of remi-neralization and correction of pH for water produced by a fuel cell (P) on board an aircraft, noteworthy in that it consists in diverting part of the water (E1) produced by the cell to at least one treatment tank (200) containing a saturation reagent and in mixing the flow of treated water (E2) issuing from the treatment tank (200) with the undiverted flow of water (E3) so as to obtain water (E5) with the desired mineralization and/or pH. The invention also relates to devices making it possible to implement said method.

Abstract: The invention relates to a method for the dynamic cleaning of supply ducts for drinking water in a vehicle (A), said method being noteworthy in that it consists in creating a shockwave (0) in the duct (210) to be cleaned.
