Title: Digital signal transmission system - has opto-electric coupler with LED shunted by transistor switch driven by Schmitt trigger
Inventor: CLAUSSEN CLAUS-JUERGEN ING GRA
IPC: H04L25/26
Filed: 1978-04-06
Abstract: The digital signal transmission system has the signal applied to a Schmitt trigger (25) and to the l.e.d. (11) in the opto-electronic coupler. The LED is shunted by a transistor switch (21) controlled by the Schmitt trigger. The switch forms an integral part of the Schmitt trigger. AC signals may be transmitted via the coupler by incorporating a rectifier. An RC filter can be used to suppress dynamic noise. The advantage lies in having precisely-defined drive voltages despite the variations in available opto-electronic couplers and in attaining high static noise suppression.

Title: Automatic tread length control in tyre prodn. - by drawing through automatically monitoring roller gap before winding on drum
Inventor: ROST HARRY
IPC: B29D30/30
Filed: 1978-05-03
Abstract: The strip of tread material is applied to a build-up drum after its actual length has been measured and altered to the desired value; one end is fixed to the drum and the strip is rolled out to its full length as it is drawn on. This saves space and cost of monitoring tread length on separate roller. A light beam at the end of the tread strip shows the extent to which its length is above/below tolerance; the width of the light beam is transmitted to a reflector. This is converted into an analogue signal and compared with desired value, the difference indicating the amt. of stretch required and controlling the width of the gap between the guide/rollers and drum.

Title: Wheel spin control circuit for car - has individual sensors on each drive wheel linked to throttle control with comparator
Inventor: SCHULZE BERND-GUIDO DIPL ING
IPC: B60K28/16
Filed: 1978-07-26
Abstract: Each drive wheel (1) is fitted with a speed sensor linked to a central electronic control which compares the outputs with a road speed signal and controls the throttle setting to ensure that the signals are brought to the same value. The signals are processed through an amplifier and a comparator circuit. The circuit provides a rapid response to wheel spin. If the two sensors provide different readings, i.e. one wheel spins, then the engine torque is reduced by lowering the reference signal until the speed difference is a minimum.
