Patent DE-3214244-A1 (DE)
Title: Test arrangement for detecting and locating contact faults in PCM devices
Inventor: OCHEL GERD
IPC: H04B14/04
Filed: 1982-04-17
Abstract: Test arrangement for identifying and locating contact errors in PCM devices. When carrying out measurements on PCM devices, conventional contact fault detection equipment for analog transmission paths may cause the quantisation distortion noise to mask the modulation of the measuring signal generated by contact errors. The quantisation distortion noise is minimised according to the invention by synchronising the frequency of the test signal (5) with the sampling frequency of the PCM device. The test signal is preferably adjusted by means of a phase shifter (2) and a control amplifier (3) so that the sampling values which are in each case separated by one period of the measuring signal (5) lie within the same quantisation stage. Through this measure, the modulation of the measuring signal (5) clearly exceeds the level of the quantisation distortion noise. <IMAGE>

Patent DE-3239050-A1 (DE)
Title: Supporting profile
Inventor: JUERGENS WALTER DR ING
IPC: B62D65/02
Filed: 1982-10-22
Abstract: For the transport of motor-car parts, in particular for automation purposes, transport frames with vertical columns are provided which receive the individual parts such as roofs, floors or the like by means of suitable swing-out mechanisms of the columns. Upon removal, these mechanisms swing back again. Said columns are disposed in supporting profiles which are welded onto the frames. Even a few tenths' misalignment of the supporting profiles, that is to say deviation from the perpendicular, for a column of 1 m or more in length results in enormous deviations at the top of the column. The supported parts slip and fall off. These deviations are, however, unavoidable owing to the welding stresses. The frames bend due to the welding heat, this heat additionally causing the individual supporting profiles to bow. Alignment entails enormous difficulties. The inventor has made it his task to eliminate these difficulties. For this reason, he proposes placing the supporting profiles on an elastic plate or elastic elements and providing them at at least three points with anchoring means. <IMAGE>

Title: Backrest frame for seats, in particular for motor vehicle seats
Inventor: SCHMALE GERHARD
IPC: B60N2/68
Filed: 1982-10-23
Abstract: A backrest frame for seats, in particular for motor vehicle seats, consists essentially of a cross-beam and backrest side panels connected thereto. These backrest side panels have connection lugs arranged at their ends for connection to joint parts assigned to the seat cushion frame, the backrest side panels having an approximately U-shaped cross-section and the side web of each backrest side panel tapering, starting from the region of its connecting lugs, up to the joining point with the cross-beam. In order to reduce the effect on the seat user of acceleration forces caused by accidents due to deflection movements of the backrest, apart from the side web of each backrest side panel the limb adjoining it at the rear is also tapered towards the cross-beam and extended in relation to the other limb. In order to increase the creasing stability with optimum use of material, at least one of the limbs, adjoining the side web, of at least one backrest side panel has inwardly and/or outwardly shaped wall parts relative to the vertical plane of the side web.

Title: Process and apparatus for isotope separation
Inventor: ALTSHULER SAUL
IPC: B01D59/34
Filed: 1982-11-29
Abstract: To separate isotopes, a particle beam (11, 12) is scattered at a standing electromagnetic wave (16). The particles can either be atoms or molecules which contain the desired isotope and at least one further isotope. The particle beam is directed perpendicularly to the standing wave, for example a light wave. For the particles, that is for the quantum-mechanical atom waves or molecule waves, the electromagnetic wave (16) with its oscillation antinodes (17) and oscillation nodes, acts as a diffraction grating. The frequency of the electromagnetic wave essentially corresponds to a transition between the energy levels of the desired isotope. In this manner, the desired isotope is spatially separated from the other isotope or isotopes by scattering or diffraction. <IMAGE>

Patent DE-3306995-A1 (DE)
Title: Circuit arrangement for telecommunications switching systems, in particular PCM telephone switching systems, with conference circuits
Inventor: MIOSGA HEINRICH DR
IPC: H04M3/56
Filed: 1983-02-28
Abstract: In a telecommunications switching system, e.g. a PCM telephone switching system, with conference circuits, the subscriber stations, which are in each case switch-connected via individual hybrid circuits to a conference circuit, are individually monitored to ascertain whether they are active, i.e. whether data signals are being transmitted by them. A composite signal, which is fed to all connected conference participant stations, is formed from the data signals of the active subscribers only. If the number of active subscriber stations rises beyond three, attenuation for the composite signal is activated in steps as the number of subscribers increases. The active subscriber stations are those which transmit a data signal which exceeds a data signal level threshold value which is greater than the highest possible hybrid return flow due to mismatching, i.e. due to a lack of transhybrid loss. <IMAGE>
