Title: Automatic control for windscreen wiper - with thin film moisture detector on outside of glass
Inventor: OHE WILFRIED VON DER
IPC: B60S1/08
Filed: 1975-05-24
Abstract: The outside of the windscreen is fitted with a thin film moisture detector in the wiped area of the glass. The detector has interdigitated electrodes and an impulse control circuit monitors the electrical learage or capacitance between the electrodes and thereby regulates the wiper speed and frequency accordingly. An integrating circuit maintains the calculated wiper speed for at least one sweep so that the wipers do not stop immediately the test area is wiped. The control circuit is connected to the test area by special electrodeso protected from moisture or through the glass, either via small holes or by capacitative coupling.

Title: Electronic ringing current converter for communication systems - performs signalling separate from speech equipment using pulsed DC
Inventor: PFEIFFER KLAUS
IPC: H04M19/04
Filed: 1975-07-21
Abstract: A half-wave of a ringing voltage superposed on a d.c. voltage is converted by a rectifier (D) in a pulsed d.c. current for a transistor (T) control. It remains conducting when a negative half-wave is applied to it, owing to a storage circuit (C2, R3). The operational d.c. voltage (UB) is used as control voltage for the transistor (T) which generates a d.c. signal display (RL). Feed-back of control voltage to the conversion circuit input is prevented by a Zener diode (2) inserted between transistor (T) base and diode (D).

Title: Strip coiler with automatic load and unload - cuts off strip after tensioned coil is fully wound with increasing dia. to lift arm
Inventor: HESSENBRUCH ROLF DIPL ING
IPC: B65H18/10
Filed: 1975-09-04
Abstract: Released from a controlled drive, a tensioned coil winds along a track, stopping without impact before cut-off. Strip (1) feeds around a pressure roller (5) to a gear (8.1) driven (7.1) coil (6) spindle (7). Increasing coil diameter lifts a pressure arm (3). Preset sizing lifts a loading arm (11) clear. The coil spindle descends a guide (9), with maintained rack (10) rotation winding. After smooth reception (15) and a finishing drive winding (15), the lowered pressure roller initiates cut-off (16). The fully raised loading lever engages an empty gear ended spindle (7.3) which enters a hook (11.1). Lever descent, spindle to strip contact, and meshing (8.1), (7.1), follow. The pressure roller strockstrip enwraps the empty spindle.

Title: One-way electronic switch - has inductor guarding against high reverse voltages at switch=off and avoids high power loss at switch=on
Inventor: BOEHRINGER ANDREAS PROF DR ING
IPC: H03K17/0814
Filed: 1976-10-04
Abstract: The one-way electric switch is designed to avoid high power loss when switched on and to withstand greater reverse voltages when switched off. An inductor is connected into every path of the circuit that carries current when the switch is switched on. This inductor limits the linear or current-dependent rate of increase of the current through the switch when switched on. Once the switch has reached a steady state, practically no current flows through this inductor. A diode/capacitor circuit is connected in parallel with the switch's main current path. The polarity of the diode is chosen to prevent current flowing in the reverse direction.
Patent DE-2654533-A1 (DE)
Title: Electronic speed control for car - has failsafe interlock to cut out automatic control if engine speed or acceleration exceed preset levels
Inventor: FLEISCHER HELMUT
IPC: B60K31/02
Filed: 1976-12-02
Abstract: The electronic speed control for the car has a fail-safe interlock which cuts out the control if the engine speed exceeds a safe maximum. Under normal conditions, the vehicle speed is compared with a reference value using a simple differential amplifier circuit. The interlock is extended so that the automatic control cuts out if the rate of rise of engine speed exceeds a set level. This prevents sudden increase of engine speed when the clutch is operated while the vehicle is slowing.

The secondary circuit contains a spark gap. An electronic short-circuit switch acts to eliminate the spark generation on exceeding a limit speed. The short-circuit switch is in parallel with the switch section of the controllable switch in the primary circuit. A control circuit is fitted to the switch and this influences the storage value of a capacitive store according to speed-proportional signals. The storage capacitor is connected with the control electrode of the electronic short circuit switch via a threshold stage.

Title: Tooth-brush sales display stand - has partitions and recesses for housing both inclined and parallel sided cases
Inventor: WEIHRAUCH GEORG
IPC: A47F7/00
Filed: 1977-02-10
Abstract: The toothbrush sales display stand comprises a box (1) divided into several units (5) by partitions (4) each with a recess (12) which extends over the entire height. The width of this recess corresponds to the toothbrush case (10) which has inclined walls at the inserted end whilst the depth of the recess corresponds to the difference in width between toothbrush cases having inclined walls and those having parallel walls. The cases are then placed with the handle end of the brush into the stand. The extra recess means that both inclined and parallel-sided cases can be displayed in the same stand with no danger of either one tipping up. There may be at least two compartments (5) in pairs next to each other with the recesses directly adjoining each other, so that the toothbrushes can always be presented in the same position irrespective of the case in which they are housed.
