Patent DE-3721955-A1 (DE)
Title: Rotary selector switch for domestic apparatuses, especially for electric cookers
Inventor: STROOP HUBERT DIPL ING
IPC: H02B1/044
Filed: 1987-07-03
Abstract: In the case of the installation of rotary selector switches in the control panel of domestic apparatuses, the problem arises that the rotary knobs are not arranged in the correctly fixed and centred installation position. In this case, the switch and/or controller housing and the shaft of the rotary selector switch to be pushed onto the switch shaft are intended to be constructed such that fixing and centring take place automatically during installation. The switch and/or regulator housing (4) are/is suspended under the influence of spring stress on a mounting strip (5) arranged behind the switch panel (11) so that they/it can nevertheless still carry out tilting and pivoting movements while the shaft (2) of the control knob (1) is being plugged on. Fixing and a defined separation setting are in this case achieved automatically by means of a fixing element (9) while the shaft (2) is being pushed onto the switch shaft (3), in that the fixing element (9) latches into the opening in the switch panel (11) and thus centres and fixes the shaft (2) therein. <IMAGE>

Patent DE-3730513-A1 (DE)
Title: Circuit arrangement for a device for controlling the idling charge in internal combustion engines
Inventor: REINDL HARTWIG
IPC: F02D41/22
Filed: 1987-09-11
Abstract: Circuit arrangements of the said type usually act on the drive of a control element, which, bypassing the throttle valve, feeds additional air to the internal combustion engine. If a fault occurs in the circuit arrangement, it can happen that the control element opens fully, thereby causing an abrupt increase of the speed of the internal combustion engine, which results in a sudden acceleration of the vehicle driven by the internal combustion engine, especially in vehicles with automatic transmission. The new circuit arrangement is intended to prevent this and in addition to maintain the functional capability of the internal combustion engine. The output stage for triggering the drive for the control element contains a current limiting circuit in its load current circuit. The current limiting circuit is designed so that, if the maximum admissible current is exceeded, it limits the current to a preset value. The circuit arrangement can be used in all devices for idling charge control and reliably prevents the sudden engine speed increase and the associated sudden acceleration of the vehicle driven by the internal combustion engine whilst simultaneously maintaining the functional capability of the internal combustion engine.

Title: Fastening device with rubber damper
Inventor: DICK RENE
IPC: F16L3/16
Filed: 1987-09-21
Abstract: The fastening device is provided with a cylindrical rubber damper (1) which is introduced into a cutout (4) of a load-bearing part (2), with a projection (5, 6) on both sides of the same, and exhibits a central through-passage (10), through which there is guided a screw-bolt (7, 7') which serves to apply axial prestressing on the rubber damper (1) and to fasten an installation part onto the rubber damper (1) or of the rubber damper (1) onto a wall, a ceiling or onto a load-bearing member. In order that said fastening device can be fitted rapidly and reliably and with the prestressing of the rubber damper (1) adjusted to the optimum extent, even by unskilled fitters, in each case one closed bush (14 and 15) is inserted into the central through-passage (10), from both sides (11 and 12, respectively) of the rubber damper (1), which bushes are provided with annular flanges (15, 17), resting on the sides (11, 12) of the rubber damper (1), and have a length which, overall, is shorter by 15 to 30% than the length of the non-stressed rubber damper (1) and corresponds to the desired prestressing. Said sound-insulating fastening device is suitable, in particular, for fastening installation lines, ventilation ducts or the like on ceilings, walls or load-bearing members and for suspending ceilings. <IMAGE>
Patent DE-3731941-A1 (DE)
Title: Remotely controllable device for connecting pipe flanges
Inventor: SCHWALBACH MANFRED DIPL ING
IPC: F16L23/036
Filed: 1987-09-23
Abstract: In order to connect one or more pipes which terminate in a common fixed flange, at small intervals one beside the other, to a corresponding number of pipes which terminate in a corresponding, common loose flange, the invention proposes a remotely controllable device, in the case of which centring and mounting aids, which are described in detail, are provided. The latter make it possible, by turning only a single screw, to connect this flange to the fixed flange and, if appropriate, also to release it from the same once again. In this arrangement, the front, hook-shaped ends of catching arms mounted in an oblique guide of the loose flange engage behind the fixed-flange border which is undercut in the form of a wedge and in which the rear ends, mounted such that they can move in a bush, of the catching arms are moved in an axis-parallel manner with respect to the pipe ends. The bush exhibits an internal thread and an internal toothing arrangement and can be moved by means of a rotatably mounted bolt provided with a gear wheel.
Patent DE-3737435-A1 (DE)
Inventor: SCHULZE GUNTER DIPL ING
IPC: G01D5/20
Filed: 1987-11-04
Abstract: The angle of rotation of a rotatably mounted winding (rotor winding 3) is determined by generating a rotary magnetic field at the site of the rotor winding (3) whose strength field vector rotates at a much higher rotational speed than the rotor winding (3), and measuring the time interval between the passage of the field strength vector through a predetermined angle position and the next positive or negative zero passage of the alternating electric current flowing through the rotor winding (3) due to magnetic induction. The rotary motion of the field strength vector is interrupted at intervals for a brief period in each predetermined angular position; during this period, the amplitude of the field strength is allowed to oscillate sinusoidally or cosinusoidally with the angular frequency of the rotating field strength vector, the time interval to the next zero passage of the alternating current flowing in the rotary winding (3) is measured, the value obtained is stored as a correction value DELTA T and substracted from values of the time interval subsequently obtained during rotation of the field strength vector until it is replaced by a correction value determined in the same way the next time the field strength vector is stationary.

Title: Apparatus for pressing covers onto book blocks
Inventor: THRANDORF HANS-PETER
IPC: B42C11/04
Filed: 1987-12-11
Abstract: The invention relates to an apparatus for pressing covers onto book blocks (1), for use in the printing industry. The object of the invention is to press the covers (5) against the glued book blocks (1) in a high-quality manner, the intention being to comply with the requirements of each article processed at the lowest possible cost. A particular aim is sufficiently deep lateral pressing, the intention being to perform the pressing operation in a comparatively low-wear manner. The horizontal movement, which is achieved by means of a push-rod (19) and crank (10) which are known per se, is superposed by a vertical stroke. In the pressing operation, the press carriage (6) has the speed at which the blocks are transported. The lateral pressing process, completed by control cams, is undertaken by lateral pressing plates (16), whose pressing movement is derived, via angled levers (18) and a double-armed lever (21), from a toggle mechanism. <IMAGE>
Patent DE-3743284-A1 (DE)
Title: Heating conductor support
Inventor: REINACHER WOLFGANG
IPC: H05B3/32
Filed: 1987-12-19
Abstract: Supports made from ceramic materials are used for the purpose of holding helically configured heating conductor at an insulating clearance from frame (rack), housing or the like. Supports of this type which have been customary to date are constructed in the form of plates and are provided with a plurality of bores which correspond to the diameter of the helix and into which the helices have to be threaded, and this naturally requires quite a large outlay on time. More favourable assembly times are achieved by means of rib-shaped supports which are provided with grooves corresponding to the diameter of the helix and which accommodate the helix. In this type of mounting, however, it is not excluded that the helix can fall out of the grooves in the event of high thermal loading. This also applies, above all, in the case of mobile heating units. In order to solve these problems, it is proposed in accordance with the present invention to provide the upper part of the plate-shaped support with at least one pair of grooves in the shape of part circles, which are open at the top and are situated opposite one another separated by the spacings of the turns of the helix of the heating conductor. <IMAGE>

Title: Motor vehicle drive with automatic infinitely variably controlled torque transducer
Inventor: KLAUE HERMANN DR ING
IPC: B60K6/44
Filed: 1987-12-19
Abstract: The automatic infinitely variably controlled torque transducer of the motor vehicle drive of the invention consists of a three-wheel planetary gear, one element of which, preferably the sun wheel, driving the short-circuit armature of a synchronous alternating current motor in the case of gearing up, a second transmission element, preferably the ring wheel being connected to the crankshaft of the engine of the motor vehicle and the axle drive being carried out by the third element of the planetary gear, preferably the web. A synchronous alternating current motor is also arranged on the front of the engine of the motor vehicle, which motor is connected to the crankshaft via a planetary drive. Here, the web of the planetary drive is driven and in the case of gearing up the sun wheel is secured by a brake. When the brake is closed, the ring wheel drives the armature of the synchronous alternating current motor. The latter serves also as starter and dynamo. Between the two alternating current motors, a frequency transformer is arranged which in the case of gearing up adjusts the control, by a microprocessor, of the frequency, that is to say the speed of revolution of the two synchronous motors is set as a function of the loading of the engine of the motor vehicle. In this way, the infinitely variable determination of the transmission is effected. <IMAGE>

Title: Electronic trip-indicator for mounting on fuses
Inventor: RUSCHE DIETER
IPC: H02H3/04
Filed: 1988-01-27
Abstract: The invention relates to an electronic trip-indicator for mounting on fuses, with an insulating casing (10) and, arranged therein, indicator electronics (12) which signal tripping of the fuse by means of electrical and, optionally, optical signals, the two connection contacts (A, B) of which indicator electronics (12) can be connected electrically to the connectors of the fuse and which indicator electronics (12) has an indicator output (44). The indicator electronics (12) has a high internal resistance (input resistors R1, R2). The indicator output (44) is formed by the contacts (5 to 8) of a bistable relay (REL1) having two coil windings (28, 40) which are each arranged in two parallel current branches and can be acted on, through drivable semiconductor switches (thyristors T2, T3) connected in series with them, alternately with current pulses so that, in the event of tripping of the fuse and a corresponding voltage rise at the connection contacts (A, B) of the indicator electronics (12), the indicator output (44) passes into a first logical switching state and, in the event of disconnection of the trip-indicator from the operating voltage and a corresponding voltage drop at the connection contacts (A, B), the indicator output (44) passes into a second logical switching state. Capacitors (C2, C3) are electrically connected in parallel in each of the two current paths having the coil windings (28, 40) of the bistable relay (REL1), which capacitors can be charged on application of the voltage to the connection contacts (A, B) of the indicator electronics (12)...
