Title: Playing ball
Inventor: RAMME HUBERTUS DIPL ING
IPC: A63F9/04
Filed: 1981-01-15
Abstract: The invention relates to a playing ball with a ball casing (1) and with a ball core (2). The ball casing (1) has, on its inside, bosses (3) replacing the corners of a polyhedron of equal faces. Arranged in the ball casing (1) as a ball core is a freely movable sphere (2) of predetermined mass, the outside diameter of which is selected smaller than the inside diameter of the ball casing (1). An eccentric mounting of the sphere (2) in the ball casing (1) is thereby achieved. The ball casing (1) has, on its outside, markings (4) which are located diametrically opposite the middle regions of the faces (5) limited by the bosses (3), for the temporary reception or fixing of the sphere (2). Consequently, always located at the top is the outer face (6) of the ball casing (1) which is provided with markings (4) and which is located diametrically opposite that face (5) which is limited by bosses (3) and in which the sphere (2) has temporarily settled into a final position for stabilising the playing ball. The polyhedron is designed as a die and therefore the ball as a die ball.   <IMAGE>

Title: Trailers for lorries
Inventor: FINSTERBUSCH PETER
IPC: B62D63/06
Filed: 1981-04-15
Abstract: The invention relates to a trailer for a lorry, which is designed as a multiple-axle trailer, the front axle of which has a pivoted bogie and a kingpin, the drawbar-support and towing device being capable of being rigidly locked. In this case, the invention is based on the object of designing the trailer in such a manner that the front axle can be used with a semitrailer, independently of the multiple-axle trailer, by uncoupling therefrom. The solution consists in that the trailer is provided with semitrailer supports in the region of its front axle and in that the front axle, with its pivoted bogie as the front carriage, can be detached from the turntable ring, can be operated as an independent unit and can optionally also be coupled to a semitrailer of known design. By this means, the front axle can be used on its own as a single-axle semitrailer. This is desirable for example in countries in which the total weight limitation for articulated road trains is limited for example to 28 t. The invention permits optimum utilisation of the vehicle. <IMAGE>

Title: Method and device for producing spiral tubes
Inventor: TSUYAMA YOSHITO
IPC: B21C37/12
Filed: 1981-04-22
Abstract: In the production of spiral tubes, the maximum required curvature of the strip for producing the tube is first determined, so that the finished tube has the desired residual moment. After bending the strip to the maximum curvature, the said strip can spring back out of the bent state. The maximum curvature is determined by taking into consideration the thickness, the Young's modulus and the yield stress of the strip and also from the desired curvature of the finished tube and its required residual moment. By adjusting the position of three rows of shaping rollers which are arranged at the corners of a triangle, the flat strip is continuously bent to form a spiral which exhibits the maximum curvature determined in this manner. The spiral-shaped strip thus obtained can spring back to the diameter of the finished tube, and the extent of this springing back is interrupted if the tube diameter is reached before complete springing back; if the springing back stops before the tube diameter is reached, the spiral-shaped strip is widened. Finally, the seam of the spiral-shaped strip is welded when the said strip has the desired final tube diameter. <IMAGE>

Title: Independently operating measuring device for testing pitch
Inventor: MEDER WILLI
IPC: G01B21/16
Filed: 1981-07-01
Abstract: A specification is given of an independently operating measuring device for testing pitch, in particular of toothed wheels (gears) but also of irregularly divided objects, by means of a probe (tracer), which can be deflected essentially tangentially relative to the specimen (sample) and can be moved on periodically between end positions rectilinearly up to the specimen and away from it. The specimen rotates continuously with the aid of its own power source, and the forward and return movements of the probe are controlled by switching means. The measuring device is also provided with means for tapping and displaying the measured value returned in the measuring position of the probe in the case of specific positions of the specimen. In order to measure the external and internal tooth systems of small and extremely small wheels, as well as to test the pitch of objects divided irregularly over the circumference, a rotary transducer rotates with the specimen. The rotary transducer is connected to a counting and computing unit by means of which it is possible to control in an adjustable fashion the feed and return of the probe, on the one hand, and the tapping of the measured values, on the other hand. The use of only one probe in conjunction with the rotary transducer eliminates a lower limit for the wheel diameter of the specimen even in the case of internal tooth systems, for which it is possible to change to an axially parallel movement of the probe.

Title: Specially shaped wrench for particular purposes
Inventor: NIESSEN BERNHARD VON
IPC: B25B13/48
Filed: 1981-09-11
Abstract: Specially shaped wrench for particular purposes, e.g. in industry on various machines, or in the household on the mixer tap of a sink, or on a car there are fastening components which it is not possible to get at using conventional wrenches. The specially shaped wrench according to the invention solves this problem in that it consists of a suitably long arm which has at one or both ends jaws or a polygonal socket, which jaws/polygonal socket are at an angle of 90 DEG  to the lever arm, with which it is possible to loosen or tighten such poorly accessible connections. For force transmission an attachment is provided which can be attached to the jaws located at the lower end. It is thus possible to work comfortably, e.g. under the sink, and loosen or tighten the nut of the mixer tap. The wrench is also useful in many other cases.

Title: Method and apparatus for X-ray diffraction spectroscopy
Inventor: TANINO MITSURU
IPC: G01N23/207
Filed: 1981-10-01
Abstract: The X-ray diffraction spectroscopy described makes it possible to obtain simultaneously a large number of diffracted X-ray beams in a very short time by irradiating specimens with strong X-rays. It is possible to use not only specimens with static properties but also those whose properties vary dynamically and which are immersed in liquids. The X-ray diffraction spectrometer, which employs the energy-dispersive method, has an X-ray source with a rotary anticathode, a specimen container, a goniometer and a computer whose program carries out the measurement and analysis. The spectrometer carries out the measurement and the analysis, it being possible to heat the specimen, corrode it, deform it under tensile stress and electrolytically machine it with the aid of various specimen holders.

Title: Device for monitoring the filling level in storage containers
Inventor: STUDER ALFRED
IPC: G01F23/60
Filed: 1981-10-16
Abstract: The device consists of an electro-optical measuring probe (1) which is surrounded by a housing (210). This housing (210) is movable independently of the probe (1). In the lower part (211) of the housing (210), there is a measuring medium (9) with a measuring surface (16). If the level to be checked of the stored product reaches the region of the housing (210), the latter is raised until the measuring medium (9) comes into contact with the optics (2) and by these means a measuring signal is generated. The probe (1) is completely enclosed by the housing (210) so that the probe (1) has no direct contact with the stored product. A part (214) of the housing (210) is of flexible design, as a result of which at least the lower housing part (211) with the measuring medium (9) is movable. The device is used in particular with stored products which are very adhesive, form residues or are corrosive, such as for example super-heavy oil. <IMAGE>
