Abstract: Economical and dependable networking of spatially separated branches of an organization is made possible for a plurality of individual subscribers with spatially separated branches by means of an arrangement and process for the operation of layer-3 virtual private networks (VPN A, VPN B) on a common data packet.communication network (e.g. OSI L3 data packet communication network 1). A logical separation of the layer-3 VPNs (VPNA, VPNB) is accomplished by allocating disjoint partial address spaces of a given homogeneous total address space to these L3 VPNs. A virtual private network identification number VPN ID is assigned to each L3 VPN and used to identify the disjoint partial address space by forming a part of the address. The VPN ID characterizing the L3 VPN starts at a fixed bit position in the individual subscriber address of each individual subscriber of the L3 VPN and may have a variable or a fixed length.

Abstract: The invention relates to a method for determining the winding temperature (TW) of the stator winding of a three-phase AC motor, in particular a pole-changeable asynchronous motor. For determining the winding temperature (TW) of the stator winding of three-phase AC motors that have an unfavorable ratio of the active power to the dissipation power and react sensitively to temperature changes and changes in a main voltage, and for readily determining the heat dissipation power (PV) from the winding temperature (TW) of the stator winding, it is proposed to determine the reference temperature (TG) and the motor current (IM) simultaneously at consecutive points in time, and to determine the winding temperature (TW) by calculating step-by-step sequentially the change in the winding temperature (TW) at a point in time (tn) and adding this change to the winding temperature (TW) of the immediately preceding point in time (tn−1).

Abstract: The invention related to a process for producing pipes, especially large pipes, as per the UOE process, wherein the pipes, after internal and external seam welding, are incrementally calibrated by cold expansion up to half the pipe length. The cold expansion is also used for straightening. For this purpose, the pipe is clamped at the shortest possible distance in front of the expander head, the free pipe end is flexibley deformed, and the pipe is then cold expanded in a known manner. The prestress force thereby decreases and then, after the release of the clamping and the remaining prestress, the pipe moves incrementally by the amount of the expander step width, up to half the pipe length. The process is then repeated for the second pipe half.

Abstract: The invention relates to a process for data exchange via a communications channel between a central unit, which processes, stores and provides data, and a data terminal device. Initially, a permanently unchanged application-independent query structure (general query structure) is stored both in the central unit and in the data terminal device, as are a small number of permanently unchanged application-independent response formats. For each application, the specific query structure is defined on the basis of the general query structure and is stored in the central unit in the form of a parameter set. As needed, the data terminal device requests from the center unit, via the communications channel, a specific query structure not yet stored in the data terminal device and receives and stores the applicable parameter set.

Abstract: A reduction in telecommunications costs in the transmission of extensive data from a telematic terminal unit in a vehicle to a central station is made possible by a method for the transmission of location data implicating the location of the terminal unit in a traffic network at a point in time and of measurement data impliciting other characteristics of the traffic network at a location and/or at a time to the central traffic station, which location data and measurement data are detected by the terminal unit, particularly a telematic terminal unit for a vehicle. At least some of the data records transmitted from the terminal unit to the central traffic station contain only location data and some of the data records transmitted from the terminal unit to the central traffic station contain measurement data.
