Patent DE-2831215-A1 (DE)
Title: Borehole surveying probe - includes TV camera, inclinometer and gyrocompass
Inventor: HENNEKE JOHANNES
IPC: E21B47/00
Filed: 1978-07-15
Abstract: Appts. for monitoring and surveying wells and boreholes on the surface and in mines during the drilling operations consists of a probe which is lowered in the hole on a self-supporting multi-core cable. The probe consists of an upper protect on tube which houses a TV camera, and a lower protective tube which houses an inclinometer and gyrocompass. All output signals are transmitted through the cable to a processor, a computer and a video recorder on the surface. The cable also carries the current for the power supply to the probe. Arrangement saves the delay in obtaining the results from probes containing conventional film cameras and eliminates re-takes if a shot has been spoilt.

Title: Receive circuit for digital time multiplexed exchange - has synchronising word comparator and two bistable flip=flops controlling serial input shift register
Inventor: ZEMANEK JOSEF DIPL ING
IPC: H04Q11/04
Filed: 1978-07-26
Abstract: The receiver circuit includes shift register with the same number of stages as there are bits in a signal block. The register is released to receive bits serially by a bistable flip flop circuit acting as a coincidence circuit. Sync. words in the register are compared with a reference sync. bit pattern. If the two are them same, the comparator resets the first flip flop and sets the second flip flop in the bistable flip flop circuit. The second flip flop is reset at the end of the receive interval.

Title: Real time measurement of tone content of noise - averaging successive maxima and minima to derive tone amplitude and frequency
Inventor: KUSCH HEINZ DIPL PHYS
IPC: G10L25/78
Filed: 1978-12-09
Abstract: The noise to be analysed is received by microphone, amplified and fed to two circuits. One circuit detects the successive maxima and minima of the fine structure and generates corres. timing pulses. The second circuit uses these pulses to sample the signal and convert the samples to digital form. Each successive pair of samples is averaged and placed in a store at a position corres. to the time of occurrence. The store is scanned to locate the positions of maxima and minima. The difference between max. and min. stored values gives the amplitude, and the number of store cells between them gives the frequency, of a tone component of the noise. The method may also be used as the basis of a computer program.

Patent DE-2901586-A1 (DE)
Inventor: HERRNRING GUENTHER DR PHIL
IPC: C25D17/00
Filed: 1979-01-17
Abstract: To prevent transport of deleterious oxygen and moisture to liquid electrolyte in an aluminum electroplating vessel, workpieces move towards the vessel through an antechamber containing inert gas under pressure and comprising a plenum chamber opening downwardly into a lock chamber containing aprotic liquid. They move down into the liquid, then up out of it, into and through an inverted-U-shaped passageway containing higher pressure inert gas and which communicates with the lock chamber below the surface of the liquid therein and communicates with the electrolysis vessel above the surface of the electrolyte. At each connection between parts, where atmospheric oxygen might move towards the electrolyte, there are double mechanical seals defining a substantially annular chamber filled with aprotic liquid that forms a gas barrier, and such liquid is, where possible, shielded by inert gas.
