Title: Touch control insensitive to dirt, moisture, etc. - has sensor introducing capacitance into pulse integrating section and Schmidt trigger followed by retriggerable monostable
Inventor: BAUMANN HEINZ DIPL ING
IPC: H03K17/96
Filed: 1977-05-25
Abstract: The touch control includes a sensory key which introduces capacitance into an RC integrating section. The input of the integrator is connected to a rectangular pulse generator. The integrator output is connected over a decoupling resistor to a Schmitt trigger circuit followed by a retriggerable monostable multivibrator whose output is the required switch function. The pulse duration of the monostable is chosen according to the pulse repetition rate of the generator and the desired noise immunity w.r.T. interference signals of a given minimum frequency which may produce undesired switching. Pref. the pulse repetition frequency should be high and the resistance (R1) of the integrating section low.

Title: Servo control for throttle linkage - increases reaction pressure if fuel consumption exceeds set limit using servo control
Inventor: LICKERT HERBERT
IPC: G05G1/015
Filed: 1977-05-25
Abstract: The throttle linkage of the vehicle is fitted with a servo operated drag brake which gives a clear indication to the driver that his fuel consumption rate exceeds a set value. The drag brake is operated by a solenoid (5) linked to the control circuit and increases the return force on the throttle setting. The drag brake operates a pivoted arm (3) which brings the drag link (2) into contact with a ratchet (8) on the throttle shaft (6). The drag link is attached to the mounting by a spring (1) which is extended as the throttle is increased. The system can be switched on in town driving to remind the driver to accelerate softly.

Title: pitch variation in keyboard instruments - involves key designed to allow string tension to be varied by way in which key is actuated
Inventor: ALLEN JOHN S
IPC: G10C3/16
Filed: 1977-11-03
Abstract: The keyboard mechanism of musical instruments is designed to allow variation in the volume dependent upon limited longitudinal movement of the keys. The keys (2) have a serrated top surface (3) to allow limited longitudinal movement. Each key is pivoted (7) onto a pin (8) with spherical housing. The striker (201) carries the string (20) that is supported in a tensioned condition over restraints (25, 27, 32, 29). The tension is dependent upon a balancing force provided by a bias spring force (21). When the key is actuated a felt pad contacts the striker to set the string in vibration. The degree of vibration is dependent upon the tension and this in turn is capable of variation by longitudinal key motion produced by the way in which the key is played.
