Title: Proximity on-off switch for hand drier - has light source and photodetector picking up light scattered from users hands beneath drier.
Inventor: BIERWIRTH VOLKER ING GRAD
IPC: H03K17/94
Filed: 1975-04-21
Abstract: The proximity on/off switch, which is used to control hand driers, switches the drier on when the person with wet hands places them beneath the unit and switches the unit off again when the person removes his hands. This avoids time-dependent switching and the possibility of incompletely dry hands and also the unhygienic aspect of a mechanical on/off switch being touched by several persons. A light-emitting element is directed down beneath the unit and a photodetector picks up the light scattered back from the person's hands and thereby triggers the heater and fan motor.

Title: Direction flasher with stabilised output - using RC chain to limit flashing rate changed by feedback variations
Inventor: GLOTH PETER
IPC: B60Q11/00
Filed: 1975-08-16
Abstract: The direction flasher circuit uses an astable layout with a single transistor (T1) and a switching relay(S). The output of the relay is monitored by a transistor stage(T2) and a reference resistor (R3) which provides a bridging circuit for the capacitor, which determines the flashing rate. This alters the flashing rate if a flasher lamp drops out. The base of the current monitoring transistor stage(T2) is tied to the output of the flasher circuit(49a) by a resistor(R9) and a capacitor(C3) whose values are set so that the max. flashing rate is limited to set bounds. The system provides a stabilising limit to compensate for feeback variations in the single transistor circuit.

Title: Actuator piston position indicator - has single control piping and double acting measuring cylinder in control desk
Inventor: HASS ULRICH
IPC: F15B15/28
Filed: 1977-03-19
Abstract: A fluid reservoir supplies a pump for discharge according to the position of the distributing valve either into the control piping or back into the reservoir. When the pump supplies the control piping the fluid reaches a measuring cylinder and the pressure moves a piston upwards. The piston carries a magnet, in contact with the terminal of wiring leading to a signal lamp. Fluid from the space above the piston is passed into an actuator to operate a valve. When the piston reaches its top terminal position, the magnet arrives within a contact with a terminal on the upper end of the piston guide tube and the signal lamp lights up, indicating that the valve is in the open position.
