Patent DE-3612855-A1 (DE)
Inventor: MEYER HANS JUERGEN DIPL ING
IPC: B65G65/48
Filed: 1986-04-16
Abstract: An unloading device at the bottom of a container for bulk material has at least one clearing arm which is supported around a pivoting axis at a distance from the centre axis of the container for bulk material and pivotably in parallel to the latter. This arrangement is designed in such a manner that when the clearing arm is rotated in the opposite direction to the operating direction of rotation, the clearing arm is pivoted around the pivoting axis in the direction towards the centre of the container for bulk material so that the outer end of the clearing arm, which is particularly heavily loaded and sensitive to wear, is accessible, for example, for maintenance purposes without having to empty the container for bulk material. As soon as the unloading device is again driven in the operating direction of rotation, the clearing arm and particularly its outer end automatically swing round the pivoting axis in the direction of the outside, that is to say in the direction of the inside wall of the container for bulk material, in which arrangement a stop, by means of which the clearing arm is fixed in its operating position, becomes effective in the final operating position. The clearing arm can be pivotably movable overall around the pivoting axis or the clearing arm can be designed in two parts, in which case only the outer part of the clearing arm is pivotable around a pivoting axis which is provided at the outer end of the outer part of the clearing arm which is rotationally rigidly connected to the drive. <IMAGE>

Title: Combustion arrangement
Inventor: BODEN JOHN CHRISTOPHER
IPC: F23G7/06
Filed: 1986-08-02
Abstract: The combustion arrangement which is suitable for disposing of combustible lean gas mixtures has a combustion chamber, a heat exchanger comprising a matrix of longitudinally running pipes for the supply of fuel lean gas to the combustion chamber and a burner arranged inside the combustion chamber. The burner is designed in such a manner that fuel gas and the combustible lean gas which emerges from at least some of the longitudinally running pipes are mixed together with one another. The heat exchanger is in a heat exchange relationship with the smoke gas emerging from the outlet of the combustion chamber. The guiding of the smoke gases from the combustion chamber via the outer surfaces of the pipes of the heat exchanger makes possible preheating of the combustible lean gas mixture before its entry into the combustion chamber. <IMAGE>

Patent DE-3634211-A1 (DE)
Inventor: SCHNAPP HERBERT DIPL ING
IPC: F27B14/08
Filed: 1986-10-08
Abstract: In the case of the present process, the gases to be drawn off during the smelting of readily smeltable metal, such as for example lead, are not drawn off directly from the space above the smelt but via a closure device which is located in the upper part of the smelting space above the smelt. This closure device is designed in such a way that it does not seal tightly during the smelting operation, so that there is constantly an air stream, if only slight, to the drawing-off apparatus. The closure may be designed as a door, swing door, double door or airlock. In any event, a gas duct leads from the drawing-off apparatus into the space which is arranged behind the non-tightly sealing door on the side facing away from the smelting space. The metal is preferably introduced into the smelting space likewise via the non-tightly sealing closure, which according to the invention has to be closed when the metal drops into the smelt. <IMAGE>

Title: Process for producing machineable ceramic
Inventor: IWASA MIKIO
IPC: C04B35/71
Filed: 1987-03-20
Abstract: Ceramics produced by the process of the present invention do not have the disadvantages of conventional ceramics which can be machined only with relative difficulty and whose use on a larger scale is ruled out despite the great hardness and the excellent abrasion (wear) resistance. A remarkably good machineability is achieved by the addition of a specified iron content to pure aluminium oxide. Although this process reduces the hardness, the abrasion resistance and the physical strength remain in an acceptable range. The good machineability is achieved according to the invention without adverse effects on the properties and advantages of the ceramic, apart from the heat resistance. <IMAGE>

Title: Circuit arrangement for the adaptive rotation-speed correction regulation of driven strip guidance and/or speed measurement rollers in the case of production and further-processing rolling arrangements for strip material
Inventor: HAUCK HERIBERT DIPL ING
IPC: H02P5/50
Filed: 1987-05-08
Abstract: In order to adapt the roller circumferential speed of a driven strip guidance and/or speed measurement roller in the case of production and further-processing rolling arrangements for strip material, the rotation-speed control loop, with subordinate current regulation, has a functional element (16) for determining those motor current levels of the roller drive motor (6) which correspond to the required rotation speeds (n1) calculated from the rolling material and rolling arrangement parameters. The motor current levels (iv) formed in this way are supplied to a correction comparison element (17). This uses them to calculate difference values as current correction values (iK) from which a correction regulator (18) forms corresponding rotation-speed correction values (nK). These pass to the rotation-speed required value adding element (9) of the rotation-speed control loop for correction of the required rotation-speed value (n'1), in such a manner that the rotation speed and hence the circumferential speed of the roller is adapted to the speed of the strip guided by it. <IMAGE>

Title: Explosion-proof window arrangement
Inventor: RUNKEL ERICH
IPC: E06B5/12
Filed: 1987-05-25
Abstract: The invention specifies an explosion-proof window arrangement (1) which, in terms of outer appearance and functioning, does not differ from conventional window arrangements. The essential feature is that a first closure element (8) is fixedly connected to the pane arrangement (6) and a second closure element (9) is fixedly connected to the masonry wall (3), a locking element (10), between the closure elements (8, 9), ensuring the fixed connection between pane arrangement (6) and masonry wall (3). The locking element (10) may be configured in both a non-releasable and a releasable manner, it being possible for releasing to take place in a pneumatic/hydraulic manner or in a mechanical manner. In the latter case, conventional rotary, lifting and pivoting fitting designs can be used in principle. Sash frame (12) and frame (13) do not have a load-bearing function, but only a design function. Window arrangements (1) of this type are suitable for tests in accordance with part D of DIN 52290. <IMAGE>

Title: Method and arrangement for monitoring phase failures
Inventor: HOLWECK PETER DIPL ING
IPC: H02H3/52
Filed: 1987-09-17
Abstract: The invention relates to a method for monitoring phase failures in a three-phase system, especially an invertor-pulsed three-phase system, in the case of which the phase currents are detected and are evaluated via bandpass filters and comparators. The object is to make such a method more reliable and simpler than known solutions and it is furthermore desired to manage using cheaper components. The solution according to the invention comprises the overall root-mean-square value of the currents (Irms) being determined via the phase currents (I1, I2, I3) and filtering, via a bandpass filter (20), out of a harmonic spectrum of the overall root-mean-square value, those harmonics which are characteristic of a phase failure, a value of the filtered-out alternating component which exceeds a threshold value triggering a phase-failure signal (PHA) via a window comparator (30). <IMAGE>

Title: Control arrangement for the sequences of operating cycles in the single-flank grinding of a gear workpiece
Inventor: BRANDNER GERHARD DR SC TECHN
IPC: G05B19/18
Filed: 1987-09-21
Abstract: The sequences of operating cycles take place in a gear-flank grinding machine which works by generation grinding with indexing control. The control arrangement includes an arithmetic unit and an interpolator. According to the invention, the component of the arithmetic unit responsible for the indexing is designed as an absolute-value former and is provided with a dividing member which reckons up the tooth number as denominator only after integral values for a reference circle periphery and for a relative tooth-gap number have been reckoned up beforehand. In each case an increment determining module is connected in series with the two interpolator inputs for desired displacement values in the carriage axis and in the rotary-table axis. During each individual cycle movement in the operating cycle, the corresponding component of the arithmetic unit is re-activated. Thus the solution obviates an accumulation of data roundings.
Patent DE-3732720-A1 (DE)
Title: Pivoting bearing
Inventor: TSCHETSCHORKE PETER
IPC: F16C19/18
Filed: 1987-09-29
Abstract: The intention is to provide a pivoting bearing with an outer ring having a partially spherical inner contact surface and with an inner ring supported rotatably and swivellably therein and provided with two rolls of rolling elements in the form of balls, and this pivoting bearing is to be distinguished by relatively low production costs and good running characteristics. This is achieved by the fact that the two rows (12) of rolling elements are arranged fully spherically in a common encircling groove (13) of approximately rectangular cross-section and are offset relative to one another in the circumferential direction. Thus only one groove has to be made to hold the rolling element. This reduces costs, as does the simplicity with which a pivoting bearing of this kind can be assembled. The offsetting of the rolling elements in the circumferential direction of the pivoting bearing gives the advantage that it is possible to dispense with the use of a cage. <IMAGE>
