Abstract: A supply system for an aircraft arranged between two dihydrogen tanks and an engine. The supply system includes a supply module that assures the flow of dihydrogen between the tanks and an outlet pipe and two heaters mounted in series on a main pipe connected to the engine. The supply system also includes a network of pipes and solenoid valves that, in the event of a problem in one of the components of the supply system, enable dihydrogen to be redirected so as to reach the engine. Also an aircraft with such a supply system.

Abstract: A method for balancing traffic among parallel links connecting two signalling points of a Common Channel Signalling System (SS7) when one or more of the links becomes unavailable. A change-over process causes SLS (Signalling Link Selection) field values originally associated with the unavailable link to be reassigned to remaining available links on a distributed basis. A change-back process, used where a previously unavailable link is restored to service, causes SLS field values to be reassigned from the other available links to the restored link.
