Abstract: A multimedia distribution network, useful on board a passenger aircraft, includes a first network node configured as a head controller, a plurality of second network nodes configured as intermediate controllers connected to the first network node, and a plurality of third network nodes configured as end device controllers, each connected to one of the second network nodes. The head controller is configured to transmit a multicast stream of multimedia control signal packets to control the end device controllers to the intermediate controllers. The intermediate controllers are configured to periodically transmit unicast delay queries to the head controller, to process the received multimedia control signal packets to the end device controllers and to distribute processed multimedia control signal packets with a controllable delay based on the content of unicast delay indicator signals sent by the head controller to the intermediate controllers in response to the unicast delay queries.

Abstract: An adsorber device for drying compressed gas comprises a first and a second chamber which operate alternately on drying and on regenerating the desiccant contained in the chambers. Regenerating is accomplished by branching-off a partial flow of dried gas at the outlet side of the chamber operating on drying and supplying the partial gas flow to the chamber working on regenerating. Means are provided for limiting the branched-off partial gas flow to the gas volume actually needed for regenerating. Embodiments are described wherein this gas limiting is accomplished with a constant partial gas flow prevailing between the two chambers and, further, embodiments are described wherein this partial gas flow is adjusted in accordance with the main gas flow through the chamber working on drying.
