Patent DE-3114714-A1 (DE)
Title: Device for realistic testing of vehicle wheels
Inventor: FISCHER GERHARD DIPL ING
IPC: G01M17/02
Filed: 1981-04-11
Abstract: The invention relates to a device for realistic testing of vehicle wheels. The loads occurring on the car wheel are simulated by two test cylinders (12, 13). In the known devices, the tyre runs on a drum, the perpendicular forces and lateral forces acting on the wheel being caused either by slipping or by camber of the wheel. As a result, due to the dependence of the lateral force on the perpendicular force such investigations can be carried out only with limitations, and in addition their level is strongly limited by the tyre strength. Moreover, wear of the tread is very great, so that it is necessary to use a plurality of tyres in an investigation, and because of variation in the coefficient of friction the testing conditions are not constant. Apart from a high outlay on time, the result is high test costs and a limitation of the testing possibilities. This problem is solved by clamping the vehicle wheel in a drum-like wheel clamp and applying the load via the rim and a loading device to which the wheel is attached. <IMAGE>

Title: Adjusting device for part of a ski binding
Inventor: WITTMANN HEINZ
IPC: A63C9/00
Filed: 1981-06-05
Abstract: The invention relates to an adjusting device for part of a ski binding, in particular for a heel-holder, which is arranged on a slide and is displaceable together with the latter on a guide rail which is fixed to the ski and can be engaged in several positions, it being possible for teeth of a catch tongue, arranged on the slide, to be engaged with tooth catches on the guide rail and to be disengaged by means of a handle, provided on the catch tongue, counter to the force of at least one spring, to which the catch tongue is subjected. The object of the invention is to design an adjusting device of the type mentioned in such a way that its engagement can take place in the simplest possible manner, that it has few components and does not release automatically even under unfavourable weather conditions and under high loading. This object is achieved in that the engagement of the teeth on the catch tongue with the tooth catches on the guide rail is secured against vertical release by a tread plate which can be pushed onto the guide rail and cannot be visibly raised from the latter, and in that the tread plate can be removably engaged against displacement along the guide rail.
Patent DE-3129115-A1 (DE)
Title: Device for measuring a torque occurring in a shaft
Inventor: KOESSLER WOLF DIETRICH
IPC: G01L3/10
Filed: 1981-07-23
Abstract: A device for measuring a torque occurring in a shaft, having two shaft sections which can be mutually rotated from a basic position against a restoring force. In this arrangement, a slide is connected to one shaft section in a manner secure against rotation but able to move axially with respect to this shaft section, and is provided with a control cam (cam path) which extends obliquely relative to a radial plane of the shaft and in which a driver arranged on the other shaft section engages in such a way that given a mutual rotation of the two shaft sections the slide executes an axial movement with respect to the shaft section carrying the driver. The slide is provided with a rotationally symmetrical reference member, which is assigned in a contact-free fashion a fixed reference member which does not change its position in the axial direction with respect to the shaft section carrying the driver. The reference members are part of a measuring arrangement which is suitable for transmitting a signal which depends on the axial separation of the reference members. A torsion bar connecting the two shaft sections preferably serves to produce the restoring force.

Title: Aircraft having a short-coupled canard wing
Inventor: STAUDACHER WERNER DIPL ING
IPC: B64C39/12
Filed: 1981-08-20
Abstract: The subject matter of the invention is an aircraft having a short-coupled canard wing. The canard wing and mainplane interfere in a dynamically favourable manner, the geometrical shape of the mainplane leading edge being matched to the downwind field of the canard control surface so that the coupling of both lifting surfaces is optimised depending on the particular manoeuvre (decoupling in the region of low incidence angle (angle of attack)/coupling in the region of relatively high incidence angle).
Patent DE-3139046-A1 (DE)
Title: Method of cleaning the piston rods of hydraulic props and device for carrying out the method
Inventor: ROSENBERG HARRY
IPC: E21D23/00
Filed: 1981-10-01
Abstract: The invention relates to a method of cleaning the areas, projecting from the cylinders, of the piston rods of hydraulic props, in particular of hydraulic supporting props in underground support, and to a device for carrying out the method. In the course of time, material is deposited on the piston rods of hydraulic cylinders. This material attacks the piston rods and ultimately causes damage to the seals. In order to be able to remove these deposits, it is proposed to clean the piston rods by means of the system's own hydraulic fluid, to which corrosion-inhibiting agents or agents increasing the cleaning effect can also be added. Furthermore, the invention proposes to either use a mobile cleaning unit consisting of hose and gun, which can be carried by the operator from one powered support assembly to the other, or remove the deposits via a cleaning device enclosing the piston rod at the top and bottom (or at both ends) in an annular manner and fitted with nozzles.
Patent DE-3143244-A1 (DE)
Title: Rolling stand for rolling bars or wire
Inventor: BRAUER HANS
IPC: B21B13/10
Filed: 1981-10-31
Abstract: The invention relates to a rolling stand for rolling bars or wire, having at least three adjustable rolls, which form a common groove opening and have cylindrical working faces. In a rolling stand of this kind, usable both in a roll block and individually, the rolls have hitherto been adjusted strictly in the radial direction and it was only possible to achieve a certain minimum groove opening which it was not possible to go beyond. Since the maximum groove opening is also limited, this gives a maximum stretching rate of the rolling stock of about 7. It is the object of the present invention to increase the stretching rate which can be achieved with such a rolling stand. For this purpose, individual rolls or all the rolls are adjusted obliquely to their working faces. In this way, it is possible to reduce the size of the groove opening to a considerable extent and even, if required, to nearly zero, resulting in a considerable increase in the stretching rate.

This cylindrical extension projects beyond the wall during plastering, painting or wallpapering, and protects the interior of the socket and the electrical installation placed within it against contamination. Once the work on the wall is completed, the socket is cut off flush with the wall or plaster.
Patent DE-3148128-A1 (DE)
Title: Solids combustion arrangement, such as a cyclone stoker
Inventor: SAXLUND ODDMUND
IPC: F23L9/02
Filed: 1981-12-04
Abstract: To safeguard the ash discharge devices in an installation with stoker firing, the complete ash discharge region is flooded with water, whereby at the same time downward sealing of the stoker against ingress of false air is achieved. Simultaneously, substantially more uniform filling of the combustion chamber with fuel is obtained by central fuel feeding, relative to the combustion chamber. The central feeding also makes it possible likewise to feed a part of the primary air in the centre. Altogether, the combustion can be made substantially more uniform and can be controlled more accurately, only partial combustion being ensured, which guarantees running at relatively low temperatures in the stoker chamber and at the same time allows vigorous postcombustion in the postcombustion region displaced to a level above the stoker.

Title: X-ray generator
Inventor: SKLEBITZ HARTMUT DIPL ING
IPC: H01J35/18
Filed: 1982-04-13
Abstract: The invention relates to an X-ray generator having an X-ray tube which has a pot-shaped anode (8, 42) whose lateral inner edge is scanned by an electron beam (22). Such tubes are used in apparatuses for investigating the internal structure of bodies. In this case, it is desirable to be able to achieve a higher loading, that is to say a higher beam yield (24). To this end, the invention provides that both the pot anode (8, 42) and the cathode (14, 40) are supported such that they can rotate about the common centre of these two parts. The increase in the load capacity of the focus spot (23), which is important for carrying out layer investigations of bodies, becomes possible by rotating the anode (8, 42) and the cathode (14, 40) in opposite directions. The invention is especially suitable for use in medical X-ray diagnostics (tomoscopy). <IMAGE>
Patent DE-3216746-A1 (DE)
Title: Feed device
Inventor: HANSELMANN MAX
IPC: H05K13/02
Filed: 1982-05-05
Abstract: In order to identify the polarity of light-emitting diodes, said diodes have different lead wires. For automatic fitment of printed-circuit boards, these lead wires must be cut to length and bent. To this end, the diodes must be supplied in the correct orientation, that is to say correctly polarised, to the device for bending and cutting to length. According to the invention, this is achieved in that a diode rotating station (7) is arranged in the feed device (2) upstream of the device (8) for bending and cutting to length, with a resistance measuring station (6) upstream of it which detects the lead wires (4, 5) electrically. <IMAGE>

Title: Method for the treatment of textiles
Inventor: VAHLDIEK JUERGEN
IPC: B65H35/00
Filed: 1982-05-04
Abstract: When using pumice for the treatment of textiles (stone-washed finish) immense problems arise:   a) various washing-machine parts, in particular the washing drum, wear severely, b) the stone slurry formed can only be removed from the textiles with high costs and causes considerable environmental problems. These problems are solved by the use according to the invention of abrasive bodies having a weight of 30 to 100 g, consisting of one or more carriers, to which is bonded an abrasive having a particle size of greater than 100  mu m and an MOHS hardness of equal to or greater than 5. The abrasive particle is in this case preferably fixed to elastic underlays, for example fabrics, which can be renewed. In a further development of the invention, the abrasion of the washing equipment can be completely suppressed by raising the edge zones of the abrasive body.

Title: Optoelectronic arrangement for resonance absorption
Inventor: POHLACK HUBERT PROF DR
IPC: H01L31/0232
Filed: 1982-07-17
Abstract: Optoelectronic resonance absorber arrangement for producing semiconductor photodetectors which can be used, in particular, in miniaturised optoelectronic arrangements. The aim of the invention is optoelectronic resonance absorber arrangements of a type which largely render surface recombination inactive, that is to say the rapid reunification of the pairs of charge carriers, formed from the penetrating radiation, on the recombinationally active surface of semiconductor photodetectors, and thus improve the quantum efficiency and other characteristic parameters of semiconductor photodetectors. The aim is achieved by mounting outside the resonance absorber optical media with suitable refractive indices, which have the effect that the absorption of the penetrating radiation directly behind the surface of the semiconductor photodetector is suppressed and concentrated on the active zones in the interior of the semiconductor. <IMAGE>

Title: Entertainment device with moving picture
Inventor: THOSS THOMAS
IPC: A63J25/00
Filed: 1982-10-07
Abstract: There is an entertainment device, in which a closed compartment (1) which can accommodate a person, has an extended inner picture wall surface (7), a seat (5) is aligned in the direction towards this picture wall surface and an apparatus (6) for producing a moving picture on the extended picture wall surface is provided. In this case, it is desirable for the viewer also to be able to take part himself in the world, the surroundings or the events in which he imagines himself to be. This is achieved in that a control element (20, 21) is assigned to the arm movement range of the seat (5). By actuating said control element via control means (15, 17), the picture moving on the extended wall surface (7) can be influenced in a controlled manner at least in respect of movement. By the combination of the extended picture wall surface and the control of the movement shown by the picture, a completely new effect is exerted on the viewer. <IMAGE>
