Title: Head rest for motor-vehicle seats
Inventor: BUTZ EUGEN OTTO
IPC: B60N2/48
Filed: 1985-05-30
Abstract: In the case of a head rest for motor-vehicle seats, the head-cushion carrier of which can be adjusted relative to the support rods, which are spatially fixed in the seat back, there is incorporated in the head-cushion carrier an electric drive motor. The electric drive motor drives two part shafts on which there is in each case seated a drive wheel in the form of a driving pinion or a friction wheel. Each drive wheel and each support rod is allocated a running track - rack or flat track. Each part shaft is rotatably connected to the drive motor via a torque transmission means, such as an overload coupling, which is at least torsionally elastic. Taking into account detrimental external forces acting on the head-cushion carrier, the head rest permits an electromotive horizontal and/or vertical adjustment of the head-cushion carrier.

Patent DE-3623783-A1 (DE)
Title: Information transmission system
Inventor: DOUVERNE EGON DIPL ING
IPC: H04B14/08
Filed: 1986-07-15
Abstract: The invention relates to an information transmission system which exhibits a digital signal channel for transmitting a digital signal and an analog signal channel for transmitting an analog signal. The digital signal is transmitted by modulating a carrier oscillation in accordance with a phase-shift-keying method. The analog signal is transmitted by frequency modulation of the carrier oscillation. In the receiving station, the carrier oscillation required for coherent demodulation is generated in a carrier generator. It is synchronised by a synchronisation signal generated from the modulated carrier oscillation. The frequency modulation produces phases errors which can cause bit errors in the digital signal. When the analog signal has high amplitudes, the synchronisation stops, which can case the transmission of the digital signal to be interrupted. According to the invention, an interference-free transmission of the digital signal is achieved even with amplitudes of the analog signal of any magnitude in that an amplitude limiter and a preemphasis network are provided in the analog signal channel in the transmitting station and a deemphasis network is provided in the receiving station. Radio relay systems can be used as information transmission systems, the analog signal channel being used as service channel.

Abstract: The invention deals with a cutting drum (1) which serves in particular as a parting tool for machines in underground mining but also for selective-cut heading machines used in tunnelling or the like. Cutting drums (1) of this type are fitted with nozzles which serve to spray liquid and are connected to a common rotary transmission leadthrough (17). The latter is located inside the cutting-drum body (7) and lies here concentrically with respect to the cutting-drum axis (3) in the area of the cutting-drum end remote from the machine body. Here, it encloses the non-rotatable cutting-drum spindle (3) or else a non-rotatable tube (15) which serves to supply the liquid and is accommodated in a central bore of the output shaft (6) of the cutting drum (1). The rotary transmission leadthrough (17) rotates with the cutting-drum body (7). Liquid is fed to it through a bore in the cutting-drum spindle (3) or through the tube (15) in the output shaft (6). It directs this liquid to the nozzles of the cutting-drum body (7) via radial lines (23). According to the proposal of the invention, the rotary transmission leadthrough (17) is to be connected to the cutting-drum body (7), or to the coupling part (9) connecting the output shaft (6) to the cutting-drum body (7), in such a way that it can perform angular movements. <IMAGE>

Title: Closed film spool for alternative use
Inventor: MEYER HERMANN DIPL ING
IPC: G03B17/30
Filed: 1986-11-07
Abstract: This closed film spool for alternative use has been designed in order to avoid the rewinding of exposed film onto the starting spool - which is necessary for particular film drives. When threaded, the end of the film is guided through a light-tight slit in the spool shell and through the slits in the two spool core sleeves, which are twisted to be aligned. By turning these spool core sleeves relative to each other the end of the film is locked with positive fitting and incidence of light through the bore of the spool core is prevented. In order that the closed spool can be used both as a full spool and as an empty spool, the spool shell is provided with two light-tight mouth slits which are arranged at a different angle to the spool centre and are necessary for different directions of winding.

Title: Device and method for checking a control circuit of a telecontrol apparatus
Inventor: KECK REINHOLD DIPL ING
IPC: H02J13/00
Filed: 1986-11-28
Abstract: In telecontrol apparatuses, before a selected control circuit (k1, A1) is connected, its resistance (R1) is checked, for safety reasons, for conformity with a tolerance band. The known measurement bridge method is conditional on all the control circuits (k1, A1; ...; kn, An) having a high level of symmetry. In contrast, the new test device allows a multiplicity of different control circuits (k1, A1; ...; kn, An) to be tested without multiplying the hardware cost for this purpose. In accordance with the new test method, the resistance (R1) of a control circuit (k1, A1) is measured in an absolute manner, is digitised and is compared by a computer unit (6) with a stored digital required value (S1). The resistance (R1) is advantageously measured by introducing a constant current (IK) into the control circuit (k1, A1) to be tested. The device is used in telecontrol apparatuses having stringent reliability requirements, for example in remote-control systems of electricity supply companies. <IMAGE>
