Abstract: An electronic route segregator is described for a telephone switching system essentially comprising electromechanical switching devices in which a plurality of line units in each case with a motor uniselector are controlled by a stored-program central unit. Each line unit contains two identical circuit units, one of which receives telephony signals, e.g. dial signals, answering signals etc or transmits meter pulses via the speech wires, while the other circuit unit controls and monitors the movements of the motor uniselector. The central unit contains two interactively-linked microprocessors, one of which ensures the selector movement of one line unit in each case via the latter's corresponding circuit unit, while the other microprocessor controls the telephone connection in time division multiplex mode.
Patent DE-3304141-A1 (DE)
Title: Bearing material with an anti-friction lining of plastic
Inventor: GOTTSCHALD LUTZ DR ING
IPC: F16C33/28
Filed: 1983-02-08
Abstract: The invention relates to a bearing material with an anti-friction lining of plastic and a metallic lining support. Expanded metal or wire mesh have hitherto been used as lining supports. However, this bearing material does not have sufficient dimensional stability and loading capacity. The adhesion of the anti-friction lining is also inadequate. This and other disadvantages are avoided according to the invention by virtue of the fact that the lining support is a finely perforated sheet and that the burr which arises in the production of the fine perforation is pressed back into the holes by calendering to an extent such that the narrowest cross-section of the hole is between the sides of the sheet. This deformation makes possible positive holding of the anti-friction lining in the holes of the perforated sheet, giving good adhesion. Due to the better dimensional stability of the perforated sheet, a better radial loading capacity and more reliable contact with the bearing wall and hence good heat removal can be guaranteed.

Title: Workpiece lift
Inventor: FELDPAUSCH HUGO
IPC: B65G47/57
Filed: 1983-03-04
Abstract: A workpiece lift with a scaffold and with a chain belt which circulates inside the scaffold and which has support elements on support plates for the workpieces which are to be raised. The technical problem to be solved by the invention concerns the vertical conveying of ordered and aligned workpieces in such a way that the order and alignment are retained. Each support element is designed as a rail segment (13) which is adapted to the workpiece and receives the workpiece in its aligned position. Each rail segment (13) interacts with a catch lever mounted on the support plate to arrest the respective workpiece. An input rail (20) which is aligned with the respective rail segment in a delivery station located at the bottom is provided in the said delivery station for the cyclically controlled feeding of the workpieces. An output rail (21) which is aligned with the rail segment in the output station is provided in the discharge station at the top. A shaped section (22) fastened to the scaffold of the workpiece lift is provided in the vicinity of the output station (21) and pivots the catch lever (14) in the output station into the release position. <IMAGE>

Title: Control device
Inventor: ARLT ERHARD
IPC: B65B57/00
Filed: 1983-03-11
Abstract: The invention relates to a control device for multipacking machines with an almost constantly moving supply belt and a multipacking table which is arranged at the outlet end of the supply belt, fans out in a longitudinally or transversely displaceable manner and is moved by means of a stepping drive gear system. The intention is to increase the lives of switching elements, while at the same time increasing the output of multipacking machines, which operate in cycles. The object of the invention is to reduce the switchability of couplings and of all switching elements. According to the invention, this problem is solved by mounting a set of contact discs comprising at least three contact discs on the drive shaft of a stepping drive switching mechanism, the circumference of which set of contact discs is divided into three switching areas and one non-switching area and the active surfaces of which set of contact discs interact with sensors. In particular, four contact discs are arranged, with the active surfaces of three contact discs arranged one behind the other and with three sensors being assigned to them in such a way that for each sensor one switching area and in the set of contact discs one non-switching area are available. The signals of the sensors are fed to a freely programmable control unit, by which all sequences of movements are controllable. <IMAGE>
Patent DE-3308993-A1 (DE)
Title: Small-size automatic hand firearm with a new breech system
Inventor: TRENNE WOLFGANG
IPC: F41A3/78
Filed: 1983-03-14
Abstract: What is shown is a possibility which allows a further significant reduction of size in the sector of hand weapons by means of a new breech system, namely the modification of the conventional Becker breech. This has, in comparison with the conventional Becker breech, a changed extractor control suitable for hand weapons and, furthermore, can be coupled to an additional delay system which, however, acts only over the permissible return travel afforded by the Becker breech. The possibility of a rapid change of the grip piece makes it possible, especially where pistols are concerned, to achieve the best possible adaptation to the particular weapon size required.
Patent DE-3310416-A1 (DE)
Title: Machine with complete balancing of the inertia effects
Inventor: VU-HAN VIET DIPL ING
IPC: F02B75/02
Filed: 1983-03-18
Abstract: The invention relates to a machine with complete balancing of the free inertia effects, which can function as an internal combustion engine, a pump or a compressor. In the nowadays customary reciprocating piston engines with the slider-crank mechanism, complete balancing of the inertia effects is not possible due to the oscillating connecting rods. The centre of gravity of the masses moves up and down along the cylinder axis in a manner which makes balancing impossible. Complete balancing of the inertia effects is, on the other hand, possible on the machine with the so-called Scotch-yoke mechanism, since the inertia effects of the second and higher orders do not occur and only the inertia forces of the first order have to be balanced. These inertia forces of the first order here occur only in the direction of piston movement, allowing them to be balanced by relatively simple means. Counterweights (11), (12) or (16) are provided for this purpose parallel to the piston unit (2),   - the resulting centre of gravity of the said counterweights describing the line of motion (17) of the centre of gravity of the piston unit (2) in the opposite direction, - and the product of the mass . crank or eccentric radius being the same for the piston unit (2) and the counterweights (11), (12) or (16).   <IMAGE>

Patent DE-3317304-A1 (DE)
Title: Device for separating glass fibres
Inventor: KRAUSE DIETER
IPC: G02B6/25
Filed: 1983-05-11
Abstract: The known devices for separating glass fibres, in which the glass fibres are passed, at least at the point where they are to be separated, parallel over an anvil (1) and are pretensioned axially by a tensioning device acting perpendicularly to the glass fibres (2) and then scribed on the anvil (1), have the disadvantage that the quality of the fracture surfaces is susceptible to wide variations. As a rule, only 30 % are of such a quality that the angular deviation from the fibre axis is less than 1 DEG  and the quality of their fracture surfaces is free of interfering notches, cracks and other irregularities. According to the invention, the reject quota can be very considerably reduced by providing in the anvil (1) a slot (12) which extends symmetrically to the scribing plane, whereby a symmetrical distribution of the tension in the glass fibre cross-section at the scribing point is reached. The dimensioning of the width (B) of the slot (12) here depends on the diameter (D) of a glass fibre (2) which is to be separated. In this way, very good results were obtained when, for the size ratio D/B of the diameter (D) of the glass fibre (2) to be separated to the width (B) of the slot (12), values between D/B = 0.125 and D/B = 0.25 are maintained. The best results are obtained if the size ratio D/B is fixed between D/B = 0.15 and D/B = 0.16. <IMAGE>
Patent DE-3318165-A1 (DE)
Title: Device for adjusting the inlet guide vanes of centrifugal machines
Inventor: OERTEL RUDOLF DIPL ING
IPC: F04D29/56
Filed: 1983-05-19
Abstract: For adjusting the inlet guide vanes of centrifugal machines, it is proposed to arrange the drive and the adjusting mechanism in the stator hub. In this arrangement, a piston coinciding with the axis of the stator is moved upwards by feeding in pressurised fluid through the hydraulic line or downwards by feeding in the pressurised fluid via the pressure line. The piston is secured against rotation by groove profiles and, on its outer circumferential surface, has coarse-pitch threads. These threads engage in a counternut which rotates during the movement of the piston, the guide vanes thus being rotated, via the transmission mechanism, by the rotation of the rotary plate connected to the counternut. The hydraulic piston can also be replaced by a feed rod which is drivable by an electric or hydraulic servomotor situated in the lower part of the stator hub. The feed rod, for its part, moves a spindle nut secured against rotation which, as already described, transmits its upwards and downwards movement to the guide vanes via a transmission mechanism.

Title: Turbines for the operation of very small machinery at the front of medical probes, catheters or the like, and for forward movement
Inventor: SCHUBERT WERNER DR MED
IPC: A61M25/01
Filed: 1983-06-03
Abstract: German Patent Specification 3111497.09 described advancing medical tubing and probes using nozzle bodies. By incorporating only few further technical elements, such as a shaft 14 and discs 15 perforated for fluid, and by introducing nozzles 19 radially relative to the longitudinal axis, such nozzle bodies can be redesigned to form turbines 18. By lengthening the shaft 10/shafts 10a and 10b at the front it is possible to provide the front of the medical probe with fittings, and this already represents very small machinery. Also described is the possibility of advancing such probes even actively forwards, by propellers 27a and 27b which are used in a protected manner there and which can also rotate in opposite directions against antitorsion, turbines 18 employed downstream in the double-tubing system 21 likewise taking care of the drive even without fluid emerging in the pathway of the body to any noticeable extent. A further development is embodied by a disobliteration probe with which it should even be possible to reopen 28 vessels previously closed by thrombi or formation of connective tissue in the region of the original lumen.

Title: Method for the preparation of ultrasonic reflection tomograms and associated device
Inventor: ERMERT HELMUT PROF DR ING
IPC: G01S7/52
Filed: 1983-06-13
Abstract: The invention relates to a method for the preparation of ultrasonic reflection tomograms and to an associated device. Tomograms from measurements by ultrasound in which every spot of the target area is scanned from every direction and the reflection signals are combined to form a two-dimensional image are usually prepared via the software using correction and filtering methods. The object is to specify a novel method which can be implemented without the use of an expensive digital computer. According to the invention, merely unidimensional filtering in the form of filtering of successively incident echo signals in the time domain is carried out and the echo signals filtered in the time domain are then summed up. The associated device merely contains, in addition to the customary units, a filter (20) for filtering of the echo signals in the time domain, the filter function (F( omega )) of this filter being predeterminable, especially as a function of the scanning movement of the ultrasound pulse shape and the amplitude distribution. The echo signals from different directions are added up in a freely writable image memory (17). <IMAGE>

Title: Display stand for shops
Inventor: KUEFFNER REINHOLD
IPC: F16B12/02
Filed: 1983-06-24
Abstract: In a display stand, which is made up of panels and guide rails, for shops, the panels have peripheral grooves along their outer contours, in which grooves catch projections of guide rails engage which, in turn, have slot guides, arranged at an angle to one another, for receiving the panels. Display stands can thus be constructed which can receive any outside dimensions depending on the size and length of the panels and guide rails and thereby form a unit with positive and frictional engagement due to the catch projection/groove engagement. <IMAGE>

Title: Method for assembly preparation of the active part of liquid-cooled transformers
Inventor: MOHR ALBERT DIPL ING
IPC: H01F41/00
Filed: 1983-09-06
Abstract: Active parts (6) of such transformers normally contain a multiplicity of insulating parts consisting of hygroscopic material whose volume is dependent on the moisture content. The active parts (6) are thus dried before installation in a transformer tank and the windings are pressed, especially in the longitudinal direction. According to the invention, the pressing of the active part (6) which follows the drying takes place in a climatic chamber (1) with dry air, and the dimensions of the windings which are achieved in this way are fixed directly in the climatic chamber (1) by means of mechanical aids. In addition, in this case, the active part (6) remains in the climatic chamber (1) until immediately before it is installed in a transformer tank, and the transformer tank is filled with cooling fluid directly after the insertion of the active part (6). The method according to the invention for preparation for final assembly of the active parts (6) is particularly expedient in the case of transformers having rated powers of several MW and/or for rated voltages above 100 kV. <IMAGE>
