Abstract: The present invention relates to a wing tip extension (7) for a wing, having an upper and a lower surface (10 and 11) and a leading edge and a trailing edge (12 and 13), the geometries of which are such that between a connection region (8), for connection with a wing, and the tip (9) of the wing tip extension (7) there is provided a continuous increase of the local dihedral, a continuous increase both of the sweepback angle of the leading edge (12) and also of the trailing edge (13), and a continuous decrease of the chord of the wing tip extension (7), and in that the wing tip extension (7) in the connection region (8) carries on from the wing in substance continuously. The wing tip extension (7) in accordance with the invention thereby ensures a significant reduction of the overall drag.

Abstract: In a mesh telecommunication network in which a hierarchic synchronization method is used for synchronizing the clock pulses of exchanges in such network, a class identification is assigned to the clock pulses of each echange corresponding to a hierarchical order of all the exchanges in the network. To maintain synchronization regardless of changes in the network configuration or failure of interconnecting lines, a synchronization identification is additionally assigned to each exchange. Each exchange transmits its class and synchronization identifications to the exchanges connected thereto, and all the identification received at any exchange are compared to determine the exchange connected thereto having the highest class identification and the highest synchronization identification in such class. The sychronizing clock pulses of such highest order exchange are then used for synchronization. Each exchange may also add to its identifications a mark to distinguish different operating conditions of the network.

Abstract: In military telecommunication networks a functional dialling number diagram is used independent from the network configuration. As the network structure in a military telecommunication network constantly changes and the subscriber can move to a different address at any moment, it is necessary to switch-through all the possible connection paths in the telecommunication network during the search for the called subscriber. So as to enable the connection set-up to be rapidly effected, connection set-up messages are transmitted outgoing from the exchange of the calling subscriber to all the exchanges connected to this exchange (parallel target search method).To reduce the traffic load in the exchanges and to shorten the connection set-up times, a timing member is started in all the exchanges when a connection set-up message arrives. After the time delay has ended, the stored connection set-up message is cancelled again.
