Title: Dynamic retarder for automatic transmission - has gearchange brakes operating on output drive
Inventor: GRABOW FRITZ DIPL ING
IPC: B60T1/08
Filed: 1979-09-01
Abstract: The dynamic retarder for an automatic transmission uses the gearchange brake (24) operating on the output shaft when the engine torque is removed. No other retarder is required to ensure a braking control. The brake operates with a controlled drag or as a parking brake. The brake operates with controlled drag in any gear ratio setting of the transmission as well as in reverse. The brake can also act as a limited torque transfer on starting and replaces the conventional dynamic torque converter.

Title: Automatic time and dimmer off-switch - has separate time duration and dimming duration control using transistor diode bridge and triac circuitry
Inventor: PECHHOLD EBERHARD DIPL PHYS
IPC: H05B39/08
Filed: 1980-02-05
Abstract: The dimmer is intended for use in apartment houses etc. on stairways etc. Two designs are available, one with an FET and the other using a transistor, in which the 'on' time is independent of the 'dim to switch-off' time. The lamp unit (V) circuit is supplied from an ac source (N) through a triac (TR). The circuit comprises a depletion type FET (T6), a diode bridge (D14-17), with a smoothing capacitor (C9) with bridging Zener diodes (Z6,Z8) across which the biassing potentials interract with the diac (D1) to control the supply triac (TR). Circuit operation is initiated by a starter capacitor (C1), and the duration of full output lighting is dependent upon the setting of the potentiometer (R13) on the FET's gate whereas the dimming time is separately dependent upon the characteristic curve of the FET and the time constant of the RC circuit (C7,R12) across the FET.

Title: Ozone generator supplied with pulsed alternating voltage - of small pulse width compared with frequency to improve generating efficiency
Inventor: DOENIG GERHARD DIPL ING
IPC: H02M5/45
Filed: 1980-07-17
Abstract: A voltage supply system for an ozone generator shapes the rectified a.c. voltage to produce a pulsed alternating voltage with steep ascending flank and variable frequency and amplitude. This is supplied to a high-voltage transformer, which in turn supplies the ozone generator. The sum (2TB) of the pulse widths (TB) of two successive pulses of opposite polarity is substantially smaller than the period (Tp) of the pulsed alternating voltage. Experiment shows that ozone is produced virtually only during the steep ascend in flank of the pulsed voltage and hardly at all after the maximum amplitude is reached. Therefore, by making the pulse width small, greater efficiency of ozone generation is achieved.

Title: Servo-driven film splicer using splicing tape - has manual override lever that uncouples drive motor
Inventor: THEER ANTON ING GRAD
IPC: G03D15/04
Filed: 1980-08-07
Abstract: The servo motor (6) for the splicer has two drive wheels (11,13) on a common shaft. A link between the gears is provided by a third, deep gear (12) on a sliding mounting on a separate shaft (17). The second gear (13) drives the operating linkage (5) for the splicer.

The splicer operates an automatic cutter as well as a feed for the splicing tape. The manual lever provides a closer control on difficult joins, and enables the splicer to operate away from power supplies. The axially displaced coupling gear provides a simple, low cost drive selector.

Title: Pressed loudspeaker membrane - has suspension ring with alternately protruding and receding pyramid impressions (NL 3.4.81)
IPC: H04R1/06
Filed: 1980-10-01
Abstract: The suspension for an electrodynamic transducer coil body and membrane consists of a flange (10) with a number of fixing holes (12), a central spherical calotte membrane (21) and an intermediate suspension ring whose outer border (41) is joined to the clamped flange (10) and whose inner border line (40) adjoins the calotte on whose cylindrical portion the moving coil is wound. The intermediate ring provides high transversal stiffness while permitting a degree of movement in a strictly axial direction. This is achieved by incorporating into the ring portion 24 pairs of pyramidal elevations (30) and depressions (32). This design permits the membrane suspension and flange to be made as a single pressed component made of 50-70 microm. aluminium sheet, and having a frequency response which at 20 kHz is only 13 db below the spectrum max. response.
Patent DE-3042198-A1 (DE)
Title: Washing machine drum - has controlled water feeds and drum speeds to ensure saturation with reduced water consumption
Inventor: ARENDT HANS F
IPC: D06F35/00
Filed: 1980-11-08
Abstract: On loading the washing machine the horizontal drum rotates at a speed to give a centrifugal force at the drum mantle of 0.2-0.6 g, and the water is fed in until the laundry has absorbed the maximum amount of 45-100 per cent of the volume. During the washing cycle the drum is rotated and then at the end the drum is accelerated for a sufficient period to extract a given volume of washing fluid. This spin drying is repeated to extract a further fluid volume. For the rinsing phase, clear water is fed in by the same amount as for washing, and the drum rotates at the same speed as in the washing cyccle. The drum speed is accelerated for spin drying between rinsing cycles. The process ensures that the washing fluid penetrates into the fabric structure, while reducing water consumption.
