Title: Plastic film as an underlay for the laying of pipes of radiant heating systems
Inventor: GRAAFMANN JUERGEN
IPC: F24D3/14
Filed: 1981-03-13
Abstract: A plastic film as an underlay for the laying of pipes of radiant heating systems is provided on one of its two surfaces with raised, strand-shaped coloured layers, the colour of which makes them stand out from the film. The said layers form at least two different square grids which are composed of longitudinal and transverse strips extending at right angles to one another and which in each case have squares which are of different sizes and are nested into one another. The grids facilitate handling of the plastic film, at the same time make the pipe-laying process clearly visible and make it possible to choose between one or other of the grids, on the basis of their different designs, for laying the heating pipes at desired intervals.

Patent DE-3122842-A1 (DE)
Title: Measuring and display device for at least one parameter of a motor vehicle
Inventor: HAUBNER GEORG
IPC: G01F25/00
Filed: 1981-06-09
Abstract: A measuring and display device for at least one parameter of a motor vehicle, in particular the fuel consumption and/or the travel speed is proposed. Sensor arrangements (13 and 14, respectively) supply to a computer arrangement (12) signal sequences which are dependent on the measured parameters. After normal conditions are set, by actuating a calibration key (T1) the sensor signals A and B, respectively, are summed during a fixed time period and/or a fixed distance and the result buffered. Subsequently, sensor signals which arrive at this time are correspondingly summed in particular by actuating a function key (T2 to T5) and the result is divided by the buffered calibration value. The result is multiplied by a scaling factor and subsequently fed to a display panel (18). Installation by the manufacturer can thus be dispensed with and continuous recalibration is possible. <IMAGE>

Title: Hydraulic control arrangement for regulating the position and/or pull for implements attached to agricultural machines
Inventor: STEPRATH WERNER
IPC: A01B63/111
Filed: 1981-08-26
Abstract: A hydraulic control arrangement (10) for regulating the position and/or pull of a plough coupled to a farm tractor via a lifting gear is proposed in which a regulating valve (11) is hydraulically activated via two full bridges (46, 47) lying downstream from a mixing valve (48). Allocated to the control spool (41) of the regulating valve (11) are two outer servo pistons (73, 73'), activated by the position-regulating circuit (46), and two inner servo pistons (78, 78'), activated by the pull-regulating circuit (47), of which the former (73, 73') have a larger, effective pressure area and can be uncoupled from the latter (78, 78') by the maximum control-spool stroke (88). Thus conflicting requirements can be fulfilled in a simple manner by the control arrangement working through high dynamics with optimum time response during pull control and with optimum stability and high adjusting accuracy during position control as a result of suitable damping. <IMAGE>
Patent DE-3137328-A1 (DE)
Title: Spool valve
Inventor: BURGDORF JOCHEN DIPL ING
IPC: B60T13/12
Filed: 1981-09-19
Abstract: Spool valves for hydraulic power amplifiers for controlling pressure-medium connections between a pressure space and a pressure source or a return are known in which a control spool is guided in an axially displaceable manner in an axial bore of a control housing with a radial feed passage and a return passage and in which the feed and return passage can be closed by a radially displaceable sealing arrangement. In known spool valves, it can be considered to be a disadvantage that high-pressure lines have to be provided at the control spool. The high-pressure lines on the one hand make the device more expensive and on the other hand exert an adhesive action on the parts coming in contact with them. In contrast, the present invention proposes to design a spool valve in such a way that the feed passage (5) and the return passage (6) can be controlled by two sealing bodies (17, 23) mounted independently of one another in the radial direction at the control spool (2). <IMAGE>

Title: Switch contact arrangement for vacuum switches
Inventor: SLAMECKA ERNST PROF DR TECHN
IPC: H01H33/664
Filed: 1981-11-23
Abstract: For vacuum switches having arc concentration when switching large currents, and with two-region contacts for spatial isolation from passing continuous currents and arc circulation - which is optimal in principle - the still unsolved problem has existed until now of commutating the initial arc from any random point of origin on the continuous current contacts without delay to the electrodes which are provided for the arc circulation. The invention solves this problem as follows: supporting bodies (3) are arranged eccentrically on supporting bolts and current supply bolts, or profiled rods, and webs (4) emerge from there, or from projections (3a) on these supporting bodies, which webs conduct the current to the contacts (5) and to the rail electrodes (6) connected thereto. The rail electrodes enclose the supporting body completely or partially, they bypass the continuous current contact completely or partially, and lead to themselves or to a subsequent rail electrode. Supporting bodies are provided for supporting the rail electrodes. For switching small inductive currents with small switching voltages, the continuous current contact is provided with a facing which consists of a fusing alloy, for example chromium/copper or of a composite material. <IMAGE>

Title: Lance for taking samples from metal melts for examination by spectral analysis
Inventor: HENNING NORBERT
IPC: C21C5/46
Filed: 1982-01-02
Abstract: Metal samples for examination by spectral analysis are taken from molten metals by means of a lance in such a way that a sample carrier with a plurality of through-bores is arranged in the lance end section immersed into the melt. During the immersion, melt flows into the bores, in whose regions the samples are formed. The sample carrier is positioned in a spectrograph. The samples are examined by spectral analysis; if the measured values of one sample deviate from those of the other samples, they are discarded. Repeated sampling from the melt is no longer necessary.

Title: Apparatus for producing tubular lengths of insulating shells
Inventor: BARTMANN HANS
IPC: B26D3/00
Filed: 1982-03-26
Abstract: An apparatus for producing tubular and stable lengths of insulating shells is proposed, which are used for the heat and cold insulation of lines and pipes. A feeding mechanism is arranged upstream of a frame which bears a moulding bar suspended freely over its entire clamping length and around which a core-lining web can be laid. In the space between this web and a further outer sheathing web (B), arranged in a tubular manner at a distance therefrom, a metered two-component foam can be filled, the preformed structure being capable of being moved through a moulding zone, adjoined to which is a cutting and diverting station, in which a cutting blade cuts open the preformed insulating shell longitudinally over about 4 DIVIDED 5 of its diameter, with the exception of the deflected-away outer sheathing. The diverting station is followed downstream by a bending-off device, which grasps the overlapping, preprofiled section of the outer sheathing web, bends it and consequently prevents it from jutting out. <IMAGE>

Title: Process for eliminating a bolster during the winding of a yarn by random winding
Inventor: SCHIPPERS HEINZ DIPL ING DR
IPC: B65H54/38
Filed: 1982-05-27
Abstract: In a process for eliminating a bolster during the winding of yarns by random winding, a change of the traversing speed takes place if the spindle rotational speed approaches a multiple of the traversing speed involving the risk of the formation of a bolster. A safety distance between the spindle rotational speed and the multiple of the traversing speed involving the risk of formation of a bolster is predetermined. The safety distance and the change of the traversing speed are in a predetermined ratio to one another. The safety distance and this ratio are selected so that multiples of the traversing speed involving the risk of the formation of a bolster are jumped in as short a time as possible as a result of a change of the traversing speed. For a multi-station textile machine with a central traversing drive, a suitable device for carrying out the process of eliminating a bolster is provided. By means of the process, spinning bobbins of novel dimensions can be produced. <IMAGE>

Title: Composition for machining surfaces of an article, process for its preparation and process for machining the surface of an article
Inventor: GAISER WERNER
IPC: C09G1/02
Filed: 1982-06-19
Abstract: Compositions for machining surfaces, i.e. for polishing and grinding, by means of rotating supported articles are prepared as ready-to-use dispersion or ointment in the form of so-called solid paste mouldings. On the one hand, the preparation, storage and transport of the dispersions is complicated and, on the other, the composition in the form of a solid paste moulding cannot be applied to the support to be machined, such as a polishing disc or roll, in sufficiently fine doses. Accordingly, the composition proposed is such that it contains at least one polishing or grinding agent and one adhesive, the latter enabling the composition to be retained on the composition support and being in the form of pourable material. The composition can be prepared in particular by a process in which at least one adhesive which, owing to the elevated temperature, is liquid and at least one polishing and grinding agent are combined and the composition is additionally cooled with stirring. In a process for the machining of surfaces of articles by means of a machining composition applied to a rapidly rotating support, the pourable composition is intended to be directly sprayed onto the support or the article to be machined.

Patent DE-3228346-A1 (DE)
Title: Musical instrument
Inventor: GLOGER ERNST ING GRAD
IPC: G10D17/00
Filed: 1982-07-29
Abstract: There are many different musical instruments. They differ not only in the structure-dependent tone colour of the sounds but also in the playable sound systems. Some instruments can thus only make music together dissonantly, if at all. Chance environmental influences on the sound systems increase the dissonance additionally. For constant music-making with musical instruments, the environmental influences on the sound system must therefore be minimalised and the sound systems optimised. Sound systems can be optimised with the aid of binary numbers and relationships of whole natural numbers. The musical instrument executed according to the patent contains an optimised sound system and the environmental influence on this sound system is minimalised by rigid material and individual sound tuning.

Title: Method and device for determining the shortest transit time differences of a laser range finder operating in accordance with the transit time principle
Inventor: HINKEL RALF
IPC: G01S17/10
Filed: 1983-07-06
Abstract: To be able to evaluate the shortest transit time differences in laser range finders which are operating in accordance with the pulse transit time method, the received pulse is used for triggering the transmitted pulse so that this feedback produces an oscillating system in which the transit time measurement can take place not via one but by several pulse round trips. Thus, time differences multiply by the number of oscillations used for the measurement, delays in the transmitting and evaluating electronics being included as constants and being determinable by measurements. The accuracy of the measurement is only influenced by fluctuations in the delay times in the circuit and not by their magnitude.
