Patent DE-3801029-A1 (DE)
Inventor: LINK HERMANN DIPL ING
IPC: H02P23/16
Filed: 1988-01-15
Abstract: A method and device for controlling the speed of a rotor. Tachogenerators, by means of which the speed of the rotor can be determined, are used for the electronic regulation of drives. The regulation accuracy of known methods is limited by the mechanical tolerance of the tachogenerator elements. A correction value is obtained according to the invention to compensate for the tolerances, in that the motor driving the rotor is initially accelerated to its nominal speed, time intervals between successive pulses are then determined, as well as the total time for one revolution, the number of pulses occurring during one revolution being used to determine an even time pattern, and the desired correction values then being determined from the deviations of the pulses from the time pattern. The invention can be used for motors in which the motor is required to carry out an accurate sequence of acceleration and braking processes as well as precisely maintaining a nominal speed. Applications are motors for digital or analog signal recording units.

Title: Elongate luminaire screen, in particular for luminaires having fluorescent lamps
Inventor: DORSCH ROLAND
IPC: F21V11/06
Filed: 1989-01-25
Abstract: The assembly of known elongate luminaire screens from longitudinal and transverse reflectors requires clamping devices for the transverse reflectors. The invention avoids these clamping devices. For this purpose, a tongue (33), pointing downward, is arranged at the upper edge of the perforations in the longitudinal reflectors (14). The rear (21) of the transverse reflectors (15), formed by two parts (19), has recesses (25) for anchoring the transverse reflectors (15) on the tongue (33). The recesses are limited on the side by in each case two oblique introduction edges (27). The introduction edges (27) merge into undercuts (29) at nose-shaped projections (28'). The space (31) between the undercuts (29) is intended for the matching accommodation of a tongue (33). The width of the tongue (33) is slightly larger than the smallest distance between the introduction edges (27). When inserting the transverse reflectors (15) into the perforations, the parts (19) and thus the legs (18) of the transverse reflectors (15) are therefore moved slightly apart. After a tongue (33) has entered into the space (31) the legs (18) of the transverse reflectors (15) spring back into their initial position or they are pressed back by tensions in the longitudinal reflectors (14) into this initial position in which the noses (28') overlap the tongue (33). For anchoring at the bottom, the transverse reflectors (15) are plugged with notches (23) at their apex onto the lower edge (24) of perforations lying opposite. <IMAGE>

Patent DE-3914888-A1 (DE)
Inventor: STEINHAGEN WOLFGANG
IPC: G01R19/04
Filed: 1989-05-05
Abstract: A circuit arrangement is described with the aid of which a control signal can be generated in dependence upon the occurrence of an extreme value of a sinusoidal oscillation. The circuit arrangement (10) includes a storage member (22) which is adapted to be charged via a diode (20) to one of the extreme values of the sinusoidal oscillation. A discharge path (26) for the storage member (22) is present, the time constant of which is so dimensioned that within the period duration of the sinusoidal oscillation an appreciable discharge of the storage member (22) takes place. A switch element (24) controllable by the charge voltage of the storage member (22) furnishes the control signal at its output (14) for the period of time during which the charge voltage at the storage member (22) is smaller than the extreme value of the sinusoidal oscillation. The circuit arrangement can be used in maintaining the oscillations of a resonance circuit stimulated to oscillate by means of a momentary HF carrier wave pulse, for instance in a transponder circuit. <IMAGE>
