Patent DE-4025522-A1 (DE)
Inventor: WOLTER-DOLL DIETER
IPC: G05D5/06
Filed: 1990-08-11
Abstract: With a method and an apparatus for detecting faulty machining of machine tools, especially grinding machines, mechanically removing surfaces, a solution is to be provided with which the occurrence of faulty machining can be directly detected during the machining of the workpiece itself. As regards the method, this is achieved in that the force exerted on the workpiece by the tool is measured as an "actual" value during the machining operation, this value is fed to an electronic data-processing device and compared with a "desired" value stored there, and the values obtained are documented. <IMAGE>

Patent DE-4035996-A1 (DE)
Inventor: BELLM HUBERT DR ING
IPC: H04J7/00
Filed: 1990-11-12
Abstract: The invention relates to a process for the simultaneous transmission of data (D1...Dn) and a timing signal (T) on a transmission channel (K). A discrete information signal (S) is formed by the superimposition of binary signals of equal modulation rate corresponding to the data (D1...Dn) of a data channel and the timing signal (T). The signals are given amplitudes which differ by a power of 2. Thus, amplitude selection of received data (ED1...EDn) and the received timing signal (ET) is possible in reception unit. With the aid of the received timing signal (ET) it is possible to set the scanning time of the received data (ED1...EDn) in a region which excludes transients. The invention is applied in data transmission, especially railway TV.
