摘要： A multispot welding machine for producing a mesh web from arrays of wire running skew to the longitudinal direction of the web and crossing one another has two endless synchronously circulating feeders which carry deflector-pins and each of which has a straight working run; the runs are uniformly spaced from one another and each defining a different one of the edges of the mesh web to be produced, a wire-layer which is movable to and fro across the feeders and arranged to lay perpendicular to the runs a number of wires alternately about a corresponding number of deflector-pins on the working runs of the two feeders, and a welding zone having means for welding the wires together at their crossover points. The wire-layer has an auxiliary drive mechanism which is capable of imparting to the wire-layer, each time after the wire-layer crosses over the working run of a feeder, an additional rapid forwards motion in a direction parallel to the working runs and subsequent backwards motion so as to form loops of the wire around the deflector-pins.

摘要： A method and a configuration for transmitting data over a radio interface which is organized into timeslots with finite radio blocks in accordance with a TDMA subscriber separation method are described. In the method, radio stations transmit, within a timeslot, at least two training sequences that are known to a respectively receiving radio station and by which the latter carries out channel estimations. The training sequences are positioned here in timeslot in such a way that the maximum distance between a data symbol and a nearest training sequence is minimized.

摘要： A radio communications system provides frequency channels which are formed both by time slots and by broadband frequency ranges, and in which information from a plurality of connections is simultaneously transmitted between mobile stations and base stations wherein it is possible to distinguish the information from different connections in accordance with a connection-specific fine structure. Frequency channels are repeatedly provided for time synchronization of the mobile stations in the downward direction in which a signal form is transmitted in addition to information from further connections. The mobile station to be synchronized determines from received signals at least one instant of the arrival of the signal form, which is subsequently used by the mobile station for time synchronization. The system is advantageously applied, for example, in TDD mode for the third mobile communications generation which combines a TDMA and CDMA subscriber separation method.

摘要： The protective holder for a thin-walled card, advantageously for an identification card with a magnetic strip or chip, has a front and rear piece attached to each other at three closed peripheral side edges so as to form a receiving space with an open edge for the card and a receiving opening at the open edge. A recess is provided in the open edge of the front or rear piece so that on insertion of the card, particularly the card with the magnetic strip, the card does not come into contact with the opening edge and is not scratched by it in the vicinity of the recess. A raised portion in the form of a ramp rising toward the open edge is provided in the piece having the recess in the vicinity of the open edge and the recess is provided under that raised portion so that no weakening of the holder occurs because of a decrease in the wall thickness of the front or rear piece. Clamping elements can be provided attached to the front and rear piece inside the receiving space to hold the card inserted in the holder. An inclined protruding portion can be connected to the piece not having the recess at the open edge to guide the card during insertion.
