Title: Device for measuring and setting angles on model aircraft
Inventor: DROMMEL BURKHARD G
IPC: A63H27/32
Filed: 1982-06-07
Abstract: In order to measure and set the incidence angle difference between mainplanes and the horizontal tail surface of a model aircraft, a straight rail (11) having a flat surface (12) is provided, two measuring arms (16 and 17) extending at right angles to the surface (12) being arranged on the flat surface, of which measuring arms at least one is adjustable longitudinally in the direction of the other. The measuring arms (16 and 17) are provided with recesses (20 and 21) for holding the leading edge and trailing edge of a mainplane or of a horizontal tail surface. In this case, these recesses (20 and 21) are arranged in such a manner that the longitudinal axes of the mainplane and of the horizontal tail surface run parallel to the flat surface of the rail when they are clamped in between the measuring arms (20 and 21). On the side of the rail (11) opposite the flat surface (12), a spirit level (22) is supported on said rail such that it can pivot in the plane of the rail (11). An adjuster (30) is provided for setting the spirit level (22), which adjuster consists of a threaded rod (31) which is provided with a left-hand thread at one end and with a right-hand thread at the other end. This adjusting rod (31) is inserted at its one end into a threaded bush (33) which is supported in a moving manner on the rail, and at its other end into a threaded bush (33) which is supported in an articulated manner on the spirit level (22). By matching the levels (25) in their null position, the inclination angle of a mainplane with respect to the horizontal tail surface can be read off on the measuring scale (27), which inclination angle corresponds to the difference in the incidence angle between the mainplane and the horizontal tail surface. <IMAGE>

Title: Double wire papermaking machine
Inventor: BRUGGER HUBERT DIPL ING
IPC: D21F9/00
Filed: 1982-06-15
Abstract: The papermaking machine contains two endless wires (2,3), which are guided together on a forming roll (1), and a headbox apparatus (16) to form a length of material. The wires (2,3) are guided in common by the forming roll (1) essentially obliquely downwards to a deflecting element (6) and then obliquely upwards to a separating roll (7), the inner wire (2), with respect to the forming roll (1), being separated, after a further deflection of the wires (2,3), from the length of material remaining on the outer wire (3). Pulp water from the outer wire (3) is centrifuged off downwards at the deflecting element (6) into a collecting container (21), while pulp water from the inner wire (2) is centrifuged off obliquely upwards at the parting roll (7) into a collecting container (22) which is arranged between the parting roll (7) and a downstream guide roller (intermediate roll 10) of the inner wire (2). A reliable removal of the pulp water before separation of the wires is thus ensured, and damage to the length of material by centrifuged water drops is prevented. <IMAGE>

Title: Hermetic, decomposition-proof cork closure for mouths with external thread
Inventor: SEIDEL WALTER
IPC: B67B3/18
Filed: 1982-07-08
Abstract: Natural cork closures are not completely tight; in particular, they are gas-permeable. As a result, wine, for example, can oxidise and evaporate. Furthermore, natural cork decays and decomposes over the course of time due to various influences. These disadvantages can be prevented by a hermetic, decomposition-proof cork closure for mouths with an external thread, in particular of bottles of wine and sparkling wine, in which a cork stopper is arranged in a screw cap, in whose cap lid a sealing insert is arranged. <IMAGE>

Patent DE-3341997-A1 (DE)
Title: Method for producing electrical energy from geothermal energy
Inventor: SCHERBAUM HELMUT DIPL ING
IPC: F03G7/04
Filed: 1983-11-22
Abstract: This method uses the relatively low and constant temperature of the neutral layer of the earths crust (between approx. 1 m to approx. 25 m deep) to condense a refrigerant (preferably R 114) which has previously been vaporised by a water circuit heated by means of geothermal energy. Even given the naturally shallow adiabatic pressure gradients of the working expansion turbines, the accommodation of very large condensation surfaces thereby rendered possible yields a very considerable generation of energy (approx. 100 to 150 MW and more, depending on shaft design). Moreover, a very simple technology (no vacuum, low working pressure, no cooling water), is yielded thereby, together with a replacement for the fossil fuels and the environmental pollution.

Title: Control of separating and braking means for the positionally correct braking of part-lengths
Inventor: BERNHARDT JUERGEN
IPC: B21B43/12
Filed: 1984-01-27
Abstract: The invention relates, in accordance with Fig. 1, to the delivery roller table of cooling beds, on which the part-lengths of rolled stock are braked in such a way that they are transferred to the adjacent cooling bed next to one another and with their front ends flush. The braking process is a critical factor for the uniform position of the part-lengths. The intention is, on the one hand, by means of additional braking magnets, to increase the braking force which is exerted on the moving part-lengths and, on the other hand, by the use of inductive sensors on the braking magnets at selected measuring locations, to improve control of the braking distance of the part-length to be braked in conjunction with improved control of the braking means. <IMAGE>
