Title: Instantaneous angle and length electrical measurement - is by comparing measurement voltage phase with reference using special transfer function
Inventor: THURNER WALTER
IPC: G01D5/243
Filed: 1978-08-24
Abstract: An electrical angle and length measurement method involves using economical devices capable of giving delay-free instantaneous measurement and display of direction and speed. Both circuits and above all maintenance costs are low and the measurements are trouble-free and accurate. The measurement voltage phase is compared with a reference register. Special transfer functions enable phase deviations for each distance caused by sensor translation or rotation to be placed in an actual value register as absolute values of distance moved for the entire path length. The values have the correct signs and are in optional units smaller than one thousandth of one millimeter or one thousandth of one degree. The binary register values are converted into decimal or segment values for display purposes. The method is suitable for control purposes.

Title: Timing circuit for signal generator - has alternating switches actuated by time control or signal generator motor
Inventor: BIHL KONRAD
IPC: G04C21/04
Filed: 1979-06-29
Abstract: The circuitry periodically releasing a signal transmitter can be used in connection with a music box whose roll carries several pieces of music. The circuitry is dependent upon a time control unit that operates a first switch with a mechanical release impulse. This first switch is coupled to the signal generator motor via a second switch. After expiration of a selected signal period, the signal generator operates the second switch. The switches are connected as alternating switches contacted by the time control or signal generator motor. The latter engages a music box mechanism with a music roller and two cam discs supporting a switching operator for the alternating switches. The cam discs have two different operating cycle radians. They are rotatable relative to each other. The resultant greater and lesser radius sections are adjustable within a certain overlapping region.

Title: Protective electro-optical coupler for telecommunications exchange - uses LED in bridge circuit including transistor with resistor across emitter-collector terminals
Inventor: EMDE KURT-LOTHAR DIPL ING
IPC: H04M7/00
Filed: 1979-06-29
Abstract: The coupling unit is based on an electronic equivalent of relay protection circuits having adjustable sensitivity thresholds, and consists of a diode bride normally blocked against quiescent line current but becoming transitionally conductive when superimposed a.c. or even strong spuriously-induced voltages are applied. In such cases the current in l.e.d.s can easily rise to destructive levels unless some form of limiting circuit is added. Accordingly, the bridge limbs are formed of light emitting elements (La and/or Lb) comprising a transistor (T) whose emitter-collector terminals are placed across a resistor (Rd) which itself forms part of a voltage divider. The base current is fed via a similar divider in which the l.e.d. is placed in series. This circuit can pass fairly high excess currents without damaging the l.e.d. (Ib) while maintaining a sensitivity threshold adjustable by one of the resistors (Rd) in the voltage divider network.
