Title: Conference system for telephone networks - uses time multiplexing to decouple subscriber's send and receive amplifiers
Inventor: STEUER BERND DIPL ING
IPC: H04M3/56
Filed: 1978-07-25
Abstract: The telephone conference system is designed so that the sending and receiving amplifiers of the individual subscriber stations are decoupled from each other without the use of hybrid circuits, repeaters or balancing networks or the like. Each subscriber's sending amplifier is connected to an a-d converter and each receiving amplifier is conected to a d-a converter. The converters are controlled by a central coding-pulse unit. The converters are further connected to AND-gates which, in turn, are coupled to the conference bus line and are controlled from a central clock unit. The decoupling of send/receive amplifiers is therefore achieved by a time-multiplex method.

Title: Fault detection in video disc recordings - identifying type of error by comparing half pictures by processing in digital logic circuits
Inventor: STECHER HELMUT DIPL ING
IPC: H04N17/06
Filed: 1978-11-30
Abstract: The fault detector is partic. for mass produced video recordings on discs on which there are two half pictures per disc revolution. An error recognised in one half picture is compared with error signals in the following 2n half frames, where n is zero or an integer. The detected errors are processed in digital logic circuits and resolved into single isolated faults in one line, faults affecting two lines in the same position on the disc, that is in two consecutive pictures, scratches affecting larger numbers of pictures, and signal failures due to faulty recording or disc reproduction resulting in 'drop-outs'. Faulty recording or reproduction is recognised if errors are detected in successive half pictures. The synchronising pulses for the error detection system may be obtained from the recorded picture synchronising data.

Title: Number selection monitoring in telephone exchange - identifying incomplete numbers and preventing immediate repetition during heavy traffic
Inventor: POLLACK WOLFGANG
IPC: H04Q3/54
Filed: 1978-12-21
Abstract: The modification relieves the load on an automatic exchange at times of heavy traffic. In such circumstances it is arranged that, following incomplete number dialling by a subscriber, the interconnection between subscriber and exchange is not interrupted when the handset is replaced in its cradle. Instead, a timer is initiated which breaks the interconnection after a preset or preselected period. At times of high load this period could be one to two minutes. The selection of the delayed disconnection routine is under the control of the exchange processor unit. such selection is programmed to take place only at times of heavy traffic. At other times the normal routine pertains, and the disconnection is made by replacing the handset.
