Abstract: The aim of the invention is to connect terminals to a communication system in a wireless manner by means of a data packet network. At least one transition device to which a short-range radio module is coupled, and a server for controlling connections to the terminals, are coupled to said data packet network. The transition device is provided with a coupling table comprising addresses of terminals which are situated within the radio coverage of the short-range radio module. The server comprises an allocation table in which a network address of the transition device which enables the terminal to be wirelessly reached is respectively allocated to an address of a terminal. According to the invention, a packet-based alignment protocol is provided in order to dynamically align the allocation table with the coupling table.

Abstract: In the method according to the invention, when the operating voltage (BS) supplied by a primary voltage source fails in a program-controlled circuit arrangement (STB), the latter is supplied with supply voltage (VS) by a standby voltage source (EQ) with a limited energy reserve. Depending on the level of the supply voltage (VS), at least one subfunction of the functions realized in the circuit arrangement (STB) is deactivated in dependence on the importance of the said functions and/or the function sequence-specific energy consumption of the said functions, the energy reserve of the standby voltage source (EQ) being optimally utilized taking account of the overall functionality.

Abstract: A communication system equipped with a central computer means is connected to a service central via a communication network, for example, a telephone network of ISDN network, for telecontrol thereof. For the information exchange between the service central and the communication system, a teletransmission module is arranged in the latter, this telecommunication module being connected to the central computer means via a computer/bus interface and via a PCM-oriented system/bus interface. An information transmission via different communication networks, preferably via the telephone network or via the ISDN network, can be set using the teletransmission module.

Abstract: A nozzle assembly has an upstream part which transforms a solid thermoplastic-resin strand into an upstream tube section which is centered on an axis and flows axially. Formations inside this upstream part impart rotation about the axis to at least a portion of the material of the upstream tube section. This upstream tube section is then deflected by a distributor radially outwardly and then forced through a plurality of generally angularly equispaced radially extending throttle passages in a throttle ring. The individual solid streams issuing from this throttle ring are united into a downstream tube section that is passed axially through a downstream nozzle part which is also provided with formations that impart rotation about the axis to at least a portion of the material of the downstream tube section. Eventually the tube issues from the downstream end of the downstream nozzle part as a large-diameter tube suitable for blow molding.
