Patent DE-4101270-A1 (DE)
Inventor: VOLEJNIK WILHELM DIPL ING
IPC: H04L5/22
Filed: 1991-01-17
Abstract: In the transmission digital signals interlaced in a multiplex signal, plesiochronic clock frequencies are also adapted by positive-zero-negative buffering. Thereby the time interval between the phase shifts can be long in relation to the time constant of a phase low-pass formed by a phase control loop on the reception side, resulting in a jitter of nearly 1 UI. This jitter can be reduced if additional buffering processes are introduced in pairs in such a way that an additional positive buffering process (PST) is followed by an identical negative one (NST) or vice versa and if the time intervals within the pairs and/or between them selected are so that the mean of the phase difference between the incoming digital signal and the outgoing digital signal on the transmitting side, both contained in the multiplex signal, remains on overage approximately constant over a given period.

Patent DE-4131691-A1 (DE)
Inventor: PRETZSCHEL JOCHEN
IPC: B01F7/00
Filed: 1991-09-24
Abstract: The invention relates to a supporting frame for a stirring device disposed in a basin containing solid-laden liquid, which supporting frame can be moved up and down along a guide tube having a rectangular, especially a square, cross-section, with the aid of a lifting appliance disposed on the supporting frame, detachably fastened members being disposed on the inside of the supporting frame which are in constant contact with the outer surface of the guide tube and serve for guiding and for linear movement.
