Title: Practical application of redundancy in semiconductor stores - using address switching between data blocks to locate faulty elements
Inventor: HAEUSELE HANS DIPL ING
IPC: G11C29/00
Filed: 1975-08-28
Abstract: The simple method is for applying redundancy techniques in the construction of large semiconductor storage tanks so that a certain number of faulty elements can be accommodated. Techniques of this kind allow a significant improvement in the proportion of usable storage blocks manufactured. A brief study of the likelihood of more than one faulty element occurring in a storage block is given, using a binominal expansion technique, and a method described whereby an address line (AO-P) to a set of storage blocks (SB1, SB2 ... SBN) can be interrogated and inverted (AO-N) if any faulty element in that address is discovered. This address is different elements for the same external address. A simple interruption of a printed circuit (6) and its replacement with a link (5) is all that is needed for this operation.

Patent DE-2631938-A1 (DE)
Inventor: WOLFER GERHARD
IPC: H04Q3/54
Filed: 1976-07-15
Abstract: The method enables not only a free-busy check of connection-specific and subscriber-specific switching devices, but also switching signal transmission, in order to identify said condition, via the same current path (c1, c2) which is through-connected via a link. The current path through-connected via the link concerned is free of voltage in the busy condition. To check whether switching devices are free, their current path is initially checked to establish whether a switching signal is currently being transmitted, whereupon, if the result of the check is negative, a marker potential is applied to the current path. The free condition of the switching device concerned is then recognised by the failure of this marker potential to reach the central control device (R) via identification circuits and via any of the further switching devices which can be connected via the switching network (K) to this switching device. Since, in this way, no superimposition of switching signals and busy potential is required, simplification is achieved in terms of the transmission and reception of the switching signals. <IMAGE>

Title: Telephone PBX signalling system - is for call charge recorders and has subscribers counter energised via common control line
Inventor: SCHMITZ RICHARD
IPC: H04Q3/62
Filed: 1976-09-30
Abstract: The branch exchange switching system with telephone call charge indication at individual subscriber stations uses a shared-signal control line (C) to transfer call charge pulses from the exchange register to the subscriber's instrument. For the transmission of the counting pulses, a separate DC potential is used to distinguish them from other identifications signals transmitted over the same control line. (Q)(D2). A Zener diode in the subscriber apparatus (ZD) having a suitable breakdown voltage matched to the amplitude of the counting pulses, causes the pulses to be transferred to the counter/indicator mechanism (GZ). The counter mechanism is switched into circuit prior to the transmission of the charge pulses, by relays operated by an identification signal from the exchange.
