Title: Winding twin disc coil for transformer - separating normal and upturned windings by Z=shaped offsets in conductor to protect insulation
Inventor: RICKERTSEN NORBERT ING GRAD
IPC: H01F41/084
Filed: 1979-09-24
Abstract: Twin coils consisting of normal and turned windings for disc coil windings of transformers and reactors are produced by winding a normal coil, measuring the necessary conductor length and marking the coil end. The same length is wound as an upturned winding. At the end of the latter, a Z-shaped offset forms the transition for the next coil. The extra turns on the normal coil are turned and laid as a turned winding against an angle. A Z-shaped offset leads from the normal winding to a plunge winding which is finally tightened from outside. The risk of damage to the conductor insulation is reduced. A normal coil (1) is first wound and its end is marked. For the turned winding (5) the same length as was required for a normal winding is wound on the normal coil (1), followed by a Z-shaped offset (6) on the conductor for the next normal coil. This section is relaid, tightened by a bracket, and a further Z-shaped offset leads from the normal to the next unturned winding.

Title: Operator cut-in facility for time multiplex exchange - using central controller re-assigning time slots and connecting coder-decoder in parallel to other time slot
Inventor: GRUETERICH HUBERT ING GRAD
IPC: H04Q11/04
Filed: 1979-09-28
Abstract: Two subscribers (TA,TB) are connected via a time-multiplex telephone exchange by the central controller assigning time slots to them on the data-bus (S). Separate time slots are used for the two directions. Speech signals are converted to and from PCM in the assigned time slots by peripheral units (AS) containing send and receive coder-decoders (CV,CR). If an operator (PL) wishes to tap the connection and talk to one subscriber (TB), the central controller reassigns (S1) the other subscriber's (TA) sending time slot the operator. It also connects (S2) the operator's coder-decoder in parallel with the other time slot. Thus the operator and one subscriber (TB) are in two-way communication. The other subscriber (TA) cannot speak to anyone but can still hear the first subscriber (TB). This scheme provides operator break-in facility without using special mixing units.

Title: Individual local control of electrical loads - by monitoring voltage depression and current with logic circuits having trip facilities
Inventor: HILBERG WOLFGANG DR ING
IPC: H02H3/033
Filed: 1980-01-25
Abstract: The installation provides local autonomous control of the load of individual consumers as one means for preventing a supply system collapse. Connected between the main fuse of a consumer spur and the load is a circuit breaker (S), under the control, for example, of a microprocessor. A voltage measurement is made between fuse and circuit breaker, and compared with the nominal supply level. Current is measured on the load side of the circuit breaker, and checked for increase or decrease. The processor operates on both these signals to determine whether local load should be shed. For example, if the voltage falls below a set minimum and the current is rising the circuit breaker is opened. Reclosure follows after a set time if the voltage has recovered to nearer the nominal value. The processor may be arranged to shed part loads before ultimately ordering the circuit breaker to open.
