Patent DE-3326963-A1 (DE)
Title: Intermediate drive for belt conveyors
Inventor: POHLE HELMUT
IPC: B65G23/14
Filed: 1983-07-27
Abstract: The conveying length of belt conveyors, especially in underground mining and tunnelling, can be significantly increased with the assistance of intermediate drives. Intermediate drives with a carrier belt are proposed, the carrier belt being guided between the driving pulley and the deflection drum in a supporting structure. In this case, the supporting structure accepts the driving pulley and a drum which corresponds with and is arranged opposite it, a longitudinally displaceable drum, over which the carrier belt coming from the driving pulley and the drum opposite it is guided onto the deflection roller, being arranged between the driving pulley and the drum opposite it. The drum arranged opposite the driving pulley is advantageously also designed as a driving pulley, while the longitudinally displaceable drum which carries out bracing and thereby exerts optimum driving forces on the upper belt of the belt conveying system is loaded and tensioned via a hydraulic cylinder with a hydro-pneumatic accumulator. The forces required for bracing of the intermediate drive can therefore be reduced to a fraction of the bracing forces normally applied up to now. <IMAGE>

Title: Process and apparatus for producing bobbins of identical running length or identical diameter from winding machines for winding continuously supplied winding material
Inventor: POEPPINGHAUS WINFRIED
IPC: B65H61/00
Filed: 1984-01-31
Abstract: The process according to the invention ensures that all bobbins produced by this process have an absolutely identical preselectable length of winding material or an exact preselectable bobbin diameter, specifically in that never more than the preselected length of winding material is wound onto a bobbin or the preselected bobbin diameter exceeded; this is irrespective of any activity by the attendance personnel. The use of bobbins as weft bobbins in circular weaving machines may be mentioned here as an example of the frequently occurring need for an exactly identical running length of winding material of all bobbins produced.

Title: Apparatus and method for cutting board material to size
Inventor: IRION PAUL
IPC: B23D33/12
Filed: 1984-02-25
Abstract: The apparatus has a marking device (3, 3') which is guided in a slidable manner on an arm (14) approximately transversely to the cutting direction of a circular saw. Furthermore, means are provided for determining the adjusting travel (A) of the marking device (3, 3'). The marking device (3, 3') is, for example, a laser unit which projects a narrow line (4, 4') onto the board material (2). If the board material (2) includes a spot which cannot be used, for example a knot (12), the marking device (3, 3') is displaced until the line (4) lies close to this spot. The adjusting travel (A) of the marking device (3, 3') is displayed on a display unit (16). The fence (1) is now displaced until the distance (x) between the fence surface (18) and the longitudinal slot (8) is equal to the length of the adjusting travel (A). If the front board (11) is now displaced up to the re-positioned fence, a longitudinal strip of width A is cut off during the next cutting-off operation.

Title: Process for producing an austempered nodular cast iron article, and the article thus obtained
Inventor: SAYASHI MAMORU
IPC: C21D5/00
Filed: 1985-03-18
Abstract: A process for producing an austempered nodular cast iron article and the resulting cast iron article, which can be a thick-walled article, are described. This is produced using a cast iron composition containing spheroidal graphite and consisting essentially of 3.0-4.0% by weight of C, 1.5-3.0% by weight of Si, 0.005-0.2% by weight of a spheroid-forming agent such as Mg, Ca and/or Ce, 0.3-0.8% by weight of Mn, 0.3-2.0% by weight of Cu, 0.2-2.5% by weight of Mo, and 0-0.3% by weight of Ni, the remainder being iron. The cast iron article is cooled from the austenite stabilisation temperature to the temperature of the transformation to troostite at a suitable cooling rate in such a way that precipitation of perlite is avoided, preferably at a cooling rate of between 10 DEG C/sec and 0.5 DEG C/sec. A fluidised-bed furnace is suitable for cooling. In the cast iron composition, the following relationship is preferably maintained: 3(Mn(% by weight) + Mo(% by weight)) + 2(Cu(% by weight) + Ni(% by weight)) >/= 7% by weight.
Patent DE-3510750-A1 (DE)
Title: Flapping drive system
Inventor: RINNAU HANS-JOACHIM
IPC: B64C31/04
Filed: 1985-03-25
Abstract: In order better to cope with the dynamic forces which occur in the case of a flapping drive, the flapping surface is split into a number of relatively small and relatively short wings which are driven individually or in groups of slowly-running reversing motors. Both linear and flapping motors as well as muscle-power-operated lever drives are conceivable as reversing motors which, since they operate virtually without any transmission, exhibit a high force-transmission efficiency. Motor forces such as muscle power can be adapted well for this purpose. As a result of splitting a drive into group drives which, incidentally, are compensated with respect to pitching oscillations (as generally occur in the case of flapping wings), as a result of the arrangement into driving wings having a supporting function and control wings, both rigid supporting surfaces and conventional control surfaces under some circumstances become superfluous, as a result of which a considerably improved flight and control behaviour is obtained than in the case of the flying machines which are now normal.

Abstract: A meter test set (8) is shown and described, using which, in the case of a meter (1), the correct connection of the current coil (2) and the starting behaviour with a small load can be tested, using a test load (9) and a current transformer (12), it being possible to connect the primary winding (13) of the current transformer (12) on the one hand to a current input connection (5) of the meter (1) and on the other hand, via the test load (9), to the voltage connection (7) of the meter (1), and it being possible to connect the secondary winding (14) of the current transformer (12) on the one hand to the current input connection (5) of the meter (1) and on the other hand the current output connection (6) of the meter (1). According to the invention, a sudden load (20) is connected in parallel with the test load (9). This ensures that correct connection of the current coil (2) of the meter (1) can be tested despite the current transformer (12). <IMAGE>

Title: Fuel injection nozzle for internal combustion engines
Inventor: FUESSNER PAUL DIPL ING
IPC: F02M61/10
Filed: 1985-05-25
Abstract: Fuel injection nozzle for internal combustion engines, with a closing spring-loaded valve needle (44) and a piston (24) enclosing the valve needle (44), which piston is subjected to the fuel pressure and acts on the valve needle (44) in the opening direction. According to the invention this is performed by way of a fuel cushion (64) which is connected by way of a throttle duct (56) with a reservoir chamber (50). The piston (24) may advantageously also control an inlet cross-section (30) leading into the fuel pressure chamber (26) of the injection nozzle as a function of the travel. By corresponding co-ordination of the parts it is possible to prolong the injection period when idling and thereby to reduce the engine noise, whereas with the full load quantity the extension of the injection time is withdrawn, thereby reducing the fuel consumption. <IMAGE>
