Patent DE-3136959-A1 (DE)
Title: Sensor arrangement for measuring the weight of the load of motor vehicles
Inventor: HANKE KLAUS-DIETER DIPL ING
IPC: G01G19/12
Filed: 1981-09-17
Abstract: The proposed sensor arrangement has the purpose of permitting the elements which form the measurement values for the measurement objective in question to be adapted to an optimum degree to the extreme interference variable environment in the region of the object of the measurement, namely the vehicle axle. In particular, the requirement for a uniform, thermal coefficient of expansion between the object of the measurement and the force sensor is fulfilled. This objective is achieved by the use of an oscillatory quartz element (9) as a force sensor as well as by it being mounted in a special force conductor (1) which is constructed as a measurement spring and made of steel. In this arrangement, the sensor is mounted in such a way that the orientation of the force which is to be applied to the oscillatory quartz element (9) and to be measured corresponds to an angle with respect to the cutting axes X', Z', of an oscillatory quartz element (9) corresponding to the AT cut type in which the alpha  value of the oscillatory quartz element (9) is identical to that of the vehicle axle (19). <IMAGE>

Title: Circuit arrangement for switching sensors (exchanges) in telephone systems having a mixing selector stage which combines subscriber points having a high traffic level
Inventor: FREYMADL GEORG DIPL ING
IPC: H04Q3/62
Filed: 1981-09-21
Abstract: In order to relieve the load on the subscriber selector stage (TW), outgoing high-calling rate lines are coupled directly via a relay mixing selector stage to one of the junction circuits (connector circuits) (RSAv) which can be used for outgoing connections. One contact of a stimulus relay (excitation relay) (C1 to C10) which is provided per input of the mixing selector stage is in each case connected in a drive line of that coupling relay (D) of the switching matrix (EK) which can be allocated to the relevant input. A potential which leads to the relevant coupling relay responding is connected to one of the control lines of the other co-ordinate in the free junction circuit which is allocated to the connection which is to be set up. The control of the relay mixing selector is designed by means of selection serial circuits such that, during the said process, only that stimulus relay is energised whose stimulus has just been processed. <IMAGE>

Patent DE-3142866-A1 (DE)
Title: Process and device for making a yarn connection by splicing
Inventor: BECKER ROLF
IPC: B65H69/06
Filed: 1981-10-29
Abstract: In order to obtain a good durable and strong yarn connection by splicing, the individual fibres of the yarn ends are made parallel and initially held next to and at a distance from one another in free space, in such a way that the fibres of the yarn ends overlap at a distance from one another, whereupon fibre tufts (147', 148') are formed by applying a homopolar electrical charge to the two yarn ends, the fibre tufts being held at a distance from one another. Thereupon, applying a contrapolar electrical charge to one of the two yarn ends, the two fibre tufts (147', 148') are so knocked into one another that they form a splice, whereupon, in this state of the yarn ends and of the splice, a yarn twist is introduced into the splice. To assist the splicing, it is possible to use electrodes (84) which contribute to the formation of the fibre tufts by means of electrostatic forces of attraction and which subsequently also contribute directly to the formation of the spliced connection by means of electrostatic forces of repulsion. <IMAGE>

Patent DE-3147706-A1 (DE)
Title: Contact spring produced from strip material
Inventor: KRESSE FRANZ
IPC: H01R33/46
Filed: 1981-12-02
Abstract: The invention relates to a contact spring (3), produced from strip material, one of the two free ends (4) of which forms a sprung contact arm while the other free end (5) is doubled over by folding at right angles to the longitudinal direction of the strip material and forms a flat plug. A strip material having a large restoring force is used for the contact spring (3) in order to ensure a reliable electrical contact by means of the sprung contact arm (4). In order to avoid the doubled over region which forms the flat plug (5) springing apart, a tongue (7) is stamped out of one limb (6) of the doubled over region, which tongue is bent out of the plane of the limb (6) such that it presses together both limbs (6 and 9) of the doubled-over end. <IMAGE>
Patent DE-3151501-A1 (DE)
Title: Electrical push-button switch, especially for motor vehicles
Inventor: BOETZ JAKOB
IPC: H01H13/60
Filed: 1981-12-24
Abstract: An electrical push-button switch, especially for motor vehicles, has a housing, a push-button which can be moved preferably linearly in the housing, a pressure piece which is held on the push-button such that it can pivot, a changeover rocker which is supported in the housing such that it can tilt, and stops on its side facing the pressure piece which limit the pivoting capability of the pressure piece, and a restoring spring which is supported on the pressure piece and on the changeover rocker. Such a switch is intended to be constructed such that the pivoting movement of the changeover rocker is initiated after only an extremely small no-load movement of the push-button. At the same time, it is intended reliably to prevent blocking of the switch such that the pressure piece runs only on the changeover rocker but does not pivot. This is achieved in that two restoring springs are provided and the two restoring springs are arranged on different sides of a plane which is defined by the pivoting axes of the pressure piece and of the changeover rocker. The two restoring springs ensure that the pressure piece is pivoted even before operation of the push-button and an extremely short no-load movement is adequate.

Abstract: In the housing according to the invention, the wheels are supported on round, angular or star-shaped discs. The latter are screwed to the legs of the housing via spacing discs which fit into countersunk depressions which are machined into the leg walls. To compensate for dimensional inaccuracies in the legs, the countersunk depressions have different depths in such a manner that their bottoms form a mounting plane for the spacing discs and thus the said discs. <IMAGE>
Patent DE-3218578-A1 (DE)
Title: Method and device for making a hem on a garment
Inventor: SIEBER PETER
IPC: D05B35/04
Filed: 1982-05-17
Abstract: When making garments, the edges of the material have to be folded over, i.e. hemmed. The preparation of the hem has previously required a relatively large amount of work since this operation had to be carried out by hand. According to the invention, making the hem takes place in that the edge of the garment, fixed by a vacuum to a backing, is held with spacing from the hem, the free edge is folded over mechanically and pressed on, the hem is then fixed by means of a jet of steam and dried by heated air which is sucked through. This operation proceeds automatically, i.e. electronically or electrically controlled. In this case, it is particularly advantageous to use a device which has an air- and steam-permeable rest (4) for a garment, a fan (5) for sucking the garment (6) onto the rest (4) by means of a vacuum, a stencil (8) with contours corresponding to the hem (7) to be made, a brush unit (10) which is displaceable, raisable and lowerable, and an ironing strip (11) with a hot steam and ironing (fresh) steam channel (12, 13) as well as means for displacing and vertically adjusting the stencil (8), brush unit (10) and ironing strip (11) and for the controllable supply of hot steam, fresh steam and hot air. In a device of this type according to the invention, the garment merely needs to be placed on, while the formation and fixing of the hem both take place fully automatically. The method according to the invention and the device according to the invention can advantageously be used, in particular in clothing factories, tailors' shops or the like. <IMAGE>
Patent DE-3218599-A1 (DE)
Inventor: FRANKENFELD KLAUS DIPL CHEM DR
IPC: C01B25/238
Filed: 1982-05-18
Abstract: The invention is concerned with a process of removing cadmium from acid, especially P2O5-containing solutions by liquid/liquid extraction with the aid of alkyl amine salts that are dissolved in an inert, organic solvent. The cadmium ions are removed from the acid, aqueous phase and are enriched in the organic phase. The cadmium-containing organic phase, subsequently, is re-extracted with an aqueous salt solution, with the cadmium ions migrating from the organic phase into the aqueous phase. The process is particularly suitable for extracting cadmium from concentrated, highly acid aqueous solutions.

Title: Vacuum tanker with distributor device for the surface distribution of media, such as, for example, liquid manure
Inventor: SCHANZ FRIEDRICH
IPC: A01C23/00
Filed: 1982-07-21
Abstract: The distributor device (V) connectable to the connection piece of the vacuum tanker comprises a pivotable elbow (77). The steel tube (83, 84) engages over the latter to form an annular channel (81). Into the annular channel opens a branch line (75), the pressure of which can be controlled by the compressor (66) of the vacuum tanker. This ensures that, if required, a distribution of the medium over a substantially larger area is possible at an acceptable extra technical outlay, because it is possible for the delivery line of the compressor to be used for increasing the throwing width. <IMAGE>

Title: Wide-strip studs for sport shoes
Inventor: MATULLA KONRAD ED
IPC: A43C15/16
Filed: 1982-09-06
Abstract: The new stud material and profilings serve for better effects in the following:   1) Better, safer starting force, lower playing field turf erosion, and reduced bodily injuries in the event of impacts against body parts. 2) The wide-strip longitudinal surfaces contribute to this, as does their type of physical profilings, such as among others twinned studs as in P.3235986.1, as does likewise their selected positioning in a hoof-shape or circular shape on the sole part, as here the stud surround encircles ground areas and via these sliding off is excluded even with low ground penetration depths, as on the other hand bodily impacts are alleviated.   All these values relate to previous stud material in spike-like round shape of a diameter of approximately 10 to 12 mm and lengths up to 16 mm, designated as so-called "screw studs" and cause these abovementioned shortcomings, and thus require new stud shapes, such as the inventor has (provisionally) called "protector studs". The subject is known worldwide as having been a problem previously and is now to be alleviated.

Title: Method for the automatic population of printed-circuit boards with semiconductor components having integrated circuits, and devices for carrying out the method
Inventor: LIST DIETER
IPC: H05K13/04
Filed: 1982-09-23
Abstract: Two similar methods are specified, as well as a device which is suitable for carrying them out, for the freely programmable, automatic positioning in the correct location, placing and fixing of semiconductor components having integrated circuits, so-called flat packs, on printed-circuit boards which may already be pre-populated. The invention provides for the removal, by means of gripping means, from a magazine cassette, a centring and alignment station, and stations (such as a rotating plate, adhesive station, engagement station and placing station) served by a three-armed turnstile, which can pivot to and fro in each case through 90 DEG , via an X-Y table for the printed-circuit board to be populated. At the location of the adhesive station, an electronic monitoring station can alternatively be used to carry out 100% functional monitoring. The adhesive station is then arranged above the X-Y table such that the small disc, which is adhesive on both sides, is pressed on to the printed-circuit board before the component is pressed on. The sequence of the steps with respect to the stations serves to ensure the required reproducible placing accuracy.

Title: Injection gun and related execution of the process for combating rising damp in masonry by borehole pressure impregnation (pressure injection process)
IPC: E04B1/64
Filed: 1983-01-26
Abstract: Process for the continuous processing of various impregnation materials on the market (siloxane, silicone, silane, methyl siliconate, water-glass and their mixtures, etc.) by the introduction of an injection gun into a previously bored 10-mm diameter borehole, wherein the gun can be arrested during the working phase by means of a ring arranged on the valve shaft, and can be frictionally sealed by rotating a quick-fitting coupling with a left-hand thread and a spring seal arranged at the front end. The process can be used for virtually all wall thicknesses, since extension pieces of any length can be fitted to the injection gun. The method can be carried out without any of the injected impregnation material being lost. A plurality of injection guns can be used alternately during the working process by actuation of the quick-fitting coupling and without the machine losing pressure. The small diameter of the boreholes, 10-12 mm, permits rapid execution and the pressure injection eliminates refilling (as with the use of plastic bottles).
