Patent DE-3315054-A1 (DE)
Title: Deformation-resistant semiconductor wafer and process for producing it
Inventor: TAENZER DIETMAR DIPL PHYS DR
IPC: C30B33/00
Filed: 1983-04-26
Abstract: The invention can be used in the production of semiconductor components and of semiconductor wafers, in particular polished silicon wafers. The object of the invention is to describe a particularly deformation-resistant semiconductor wafer which can be treated at high temperature and to provide a method of producing such wafers. The task includes achieving the object even for extreme high-temperature treatment and of ensuring a high wafer breaking strength. The novel wafer is characterised by the existence of at least one recess and of an opening in the interior of the wafer, the opening forming a continuous connection between the interior and the exterior. The process for producing such wafers makes use of novel and known steps in crystal pulling for mechanical, radiological, thermal and/or chemical processing and can be carried out in various versions.
Patent DE-3317385-A1 (DE)
Title: Method for operating terminals of a digital subscriber access
Inventor: KESSLER ARTHUR DIPL ING
IPC: H04M19/08
Filed: 1983-05-13
Abstract: If a large number of terminals which are fed via a power supply device are connected to a digital subscriber interface at the subscriber end, the data transmission and the power feeding occurring via a multi-wire data line and additional power feeding being available from the switching system via the subscriber line which is only sufficient for supplying a few terminals, a corresponding message is sent from the subscriber-end subscriber interface via the data line to the terminals when the energy (for example mains) feeding the power supply device is missing, whereupon the terminals signal emergency operation to the switching system. The terminals are correspondingly identified in the switching system. Due to the different operating classes allocated to the individual terminals, restricted operation with different operating states is possible with only a few predetermined terminals.

Title: Method for improving subjective image quality
Inventor: HAUSDOERFER MICHAEL DR ING
IPC: H04N5/14
Filed: 1983-10-29
Abstract: A method for improving subjective image quality of television signals which are scanned in a time-discrete manner is proposed, the television signals in each case being filtered before scanning and during reconstruction.

Patent DE-3339494-A1 (DE)
Title: Method for parking vehicles at holding devices of a track which is at an incline and a device for carrying out the method
Inventor: SCHMALL JUERGEN DIPL ING
IPC: B61B1/00
Filed: 1983-10-31
Abstract: In the inclined tracks of a shunting system, buffer blocks (H) which can be raised or lowered or folded down as required are arranged. The vehicles (F1 to Fx) to be shunted are moved up to these buffer blocks by means of a locomotive (R) and then braked to a standstill by applying the vehicle brakes. After the buffer blocks are raised, the vehicle brakes are released in a metered fashion. This takes place by ventilating the compressed air line to which the vehicles are connected. Feeding occurs via a flexible line (L) either from the compressed air system of the locomotive or from a separate compressed air system. During this process, the vehicles automatically close up to the buffer blocks. The buffer blocks can not be lowered or folded down again until a hump locomotive (A) which has moved up to the vehicles has drawn the vehicles off the buffer blocks. <IMAGE>

Title: Azimuth sensor
Inventor: ITAKURA TOSHIO
IPC: H01F1/153
Filed: 1983-12-21
Abstract: An azimuth sensor has a core (1) which is formed by rolling together a layer of a thin metallic strip produced by means of a fast tempering method. In particular, a thin strip of an amorphous cobalt-based magnetic alloy is used which has a magnetic high-frequency characteristic which is characterised by a coercive force Hc of less than 24 A/m. A primary coil (2) is wound essentially uniformly along a magnetic path of the core (1). A secondary coil (3) has two sub-coils (3a, 3b) which are at right-angles to one another and the diameter of which corresponds to an external diameter of the core (1). A magnetic flux is generated in the core (1) by exciting the primary coil (2), and the components of the magnetic flux on opposite sides of each sub-coil (3a, 3b) are influenced by the earth's magnetism in such a manner that a differential change by an amount which is used for detecting an azimuth occurs. <IMAGE>

Title: The maize-threshing machine SMD 6
Inventor: MIKOSOVITS ADRIAN
IPC: A01F11/06
Filed: 1984-07-24
Abstract: The maize-threshing machine SMD 6 is intended especially for threshing the maize ears without husk leaves which are stored in silos, barns or tall piles; it is fed by free flow and carries out the cleaning of the beans, the loading of the beans and stalks into the transport means and the loading of the beans into the bags. The threshing machine is characterised in that, owing to the low feed height, it works at maximum speed, even when it threshes maize stored in low piles; in this case, feeding is carried out by hand shovelling with minimum effort. The maize-threshing machine is characterised in that, for the purpose of increasing productivity and in order to produce a simple and compact unit, the active members are mounted on two parallel axles inclined at 20 DEG  (relative to the horizontal) and placed one above the other. The maize-threshing machine SMD 6 is the result of a thorough study on the basis of years of experience. The main indexes of the maize-threshing machine SMD 6 (addition 1) ensures that it has a comprehensive range of use and eliminates its competition. The description of the invention (addition 2) and the bibliographic note (addition 3) are documents for patenting the threshing machine. The construction particulars (addition 4) serve for designing the threshing machine.

Title: WC/flushing cistern arrangement
Inventor: MUELLER HANS
IPC: E03D11/00
Filed: 1984-09-28
Abstract: In the case of a WC/flushing cistern arrangement, the WC body (15) has, at its rear upper end, a supply opening (16) for flushing water. A flushing cistern (18) is arranged above this end and has, at the bottom, a discharge opening (20) for flushing water. A connecting member (24) is located between the discharge opening (20) and the supply opening (16). In the case of said member, the spacing between the supply and discharge elements can be varied in the horizontal direction, in particular in the longitudinal direction of the WC/flushing cistern arrangement. Dimensional differences, such as often arise in practice due to different distances (d2), from the wall, of the discharge pipe (12), provided in the floor, for the WC body (15) or due to dimensional differences of the WC body (15) itself, can thus be compensated for, with the result that the flushing cistern (18) can be arranged in each case directly on the wall (10). <IMAGE>
