Abstract: The invention concerns a method of treating the pipes of the drinking water network of an aircraft for cleaning purposes, said network comprising at least one storage tank and a plurality of pipes providing a plurality of water inlet and outlet points, notable in that it involves the following operations: —injecting water at a high temperature of between fifty and one hundred degrees Celsius into the network, for treatment purposes, —draining, —injecting cold water at a temperature no higher than thirty degrees Celsius combined with chemical treatment products comprising a chlorinated product or hydrogen peroxide, —draining, —injecting water at a high temperature of between fifty and one hundred degrees Celsius for rinsing purposes, eliminating the chemical treatment products comprising a chlorinated product or hydrogen peroxide, —draining. Applications: cleaning the drinking water network of an aircraft.

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 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.
