Title: Mine gallery profiling roller cutter machine control - involves comparison of staged machine and roller movements, and consequent drive modulation
Inventor: DOERRIE KARL-HEINZ DIPL ING
IPC: E21C35/10
Filed: 1978-10-03
Abstract: A gallery cross-sectional profile in an underground mine is produced by means of the swivelling cutter roller on a roller cutter machine (3) guided on a conveyor (4). The transverse thrust movement of the machine, and swivelling movement of the cutter roller generating circular profiles, are divided, starting from a predetermined reference point, into a series of part stages. During cutting they are compared with each other, with reference to actual and correct positions. Excessive deviations from a correct position are compensated by modulating the drive generating the next movement in the sequence. This provides accurate contouring without involving difficult manual work.

Patent DE-2912481-A1 (DE)
Inventor: BLUETHGEN BJOERN
IPC: G11B27/038
Filed: 1979-03-29
Abstract: A method is disclosed for the joining or mixing-in or fading of two program segments which appear in the form of digital pulse sequences, free of interfering signals, particularly audio signals digitally stored on magnetic tape, whereby code word sequences which are present in both signal segments in the region of an editing location or fading location are scanned, together with their associated time codes, and are fed to respective intermediate memories. Then, by an acoustically-monitored cyclical circulation of the contents of the intermediate memories, controlled in frequency and direction, an editing location of comparable information for each program segment is determined which is free of interfering signals. A transition, controlled by the time codes is then occasioned from the first signal segment to the second signal segment or a fading of the second signal segment is occasioned relative to the first signal segment. The two time codes which are associated with the editing locations are read for carrying out a mechanical and/or electrical connection of two signal program segments which are acoustically free of interfering signals at the proper time corresponding to a common edit point identified by the two time codes.

Title: Early warning engine malfunction monitor - includes vibration and speed transducers for power spectrum comparison against stored reference pattern
Inventor: SCHEUFLER HARALD DIPL ING
IPC: G07C5/08
Filed: 1979-06-01
Abstract: Advance warning of faulty operation of an engine is derived by comparing the vibration spectrum of a new engine with that obtained from a pick-up. The latter may be in the form of a microphone attached to engine near the crankshaft and connected to a comparator. In addition, speed and temp. transducers provide signals for memory connected to an a-d converter and power spectrum analyser. The decomposition of the vibration spectrum allows specific components separation to be carried out for discrimination with reference to the pattern stored in the memory. As a result, the stored data ensures that abnormal behaviour of engine can be detected and the faults corrected in time.
