Patent DE-19743167-A1 (DE)
Inventor: BRAKEMEIER ACHIM
IPC: H04H20/72
Filed: 1997-09-30
Abstract: The invention relates to a communications system for digital data transmission in the long, medium and short-wave ranges. The data to be transmitted are advantageously distributed over several channels (ZF0, ZF1, ZF2) and then transmitted in each channel in carrier modulation mode (Mod). This means that the level of complexity of the equalisation filter used at the receiver end remains low, even with long anticipated echo transmission times. One of the channels is preferably used as a reference channel. Synchronisation parameters are drawn from this reference channel and applied to all of the channels.

Filed: 1998-05-15
Abstract: The assembly to apply a finish to the surface of a moving web, and especially of cardboard, is a polishing station with at least two polishing rollers forming a press gap between them for the web passing through. A hard roller and a soft roller form a pair of rollers (2-4). An applicator (5), to form a film on the web surface, is directly at least at one of the two rollers in a pair (2-4). A number of roller press gaps (P1-P3) are formed by the paired rollers (2-4), arranged vertically or horizontally on the direction of web (B) travel. The paired rollers (2-4) are arranged with a hard roller and a soft roller, which are in parallel opposite each other, with the hard rollers on one side of the web (B) and the soft rollers on the other side. The paired rollers (2,3) can be offset from each other, without a gap between the pairs, so that they form an additional press gap in the direction of web (B) travel. The applicator can be a jet applicator with a doctor roller with a smooth or ridged surface, or a doctor blade, a sump applicator (5) or a free-stream jet system. It can also be a roller applicator with a transfer roller. The applicator (5) is at the hard roller of the paired rollers. The press gaps (P1-P3), between the paired rollers (2-4) exert an adjustable linear force independent of the roller loading.
