Title: Anomaly detector for automatic telephone switching networks
IPC: H04Q3/42
Filed: 1974-06-28
Abstract: 1480595 Automatic exchange systems S SARRIC J HUGON and J BROSSERON 28 June 1974 [28 June 1973] 28750/74 Heading H4K Anomalies recurring in a marker controlled cross-bar switching network are recorded in binary coded former in a register. The anomalies described include: use of overflow links, and internal or external blocking. Anomalous behaviour usually occurs in conjunction with a marking of the line or trunk frames in which case the identity of the switch outlet is also recorded in binary format. If the register is unavailable, e.g. due to slow print-out, a lost messages counter is incremented. Fig. 5 depicts a pair of system markers 11, 21 each of which controls a line or trunk frame over the marking multiples SLA-SLD. Each marker is coupled via an independent monitoring circuit 12-15 and 22-25 to a common print-out unit 32. The markers supply 3-digit line and 2-digit trunk frame data in 2 out of 5 code to a transcoder 14 which converts the data into binary. Whenever the transcoder is enabled, even if the data supplied thereto is invalid, e.g. more or less than 2 of the 5 wire multiples marked, it causes an anomalies coder 13 to start a programmer 17. Anomalies coder 13 is also operable to convert anomaly signals in 2/5 code from a marker into binary code for submission to the register 15. This is a set of bi-stables controlled by a 4 phase clock which is effective to gate the data in the transcoder 14 and the coder 13 into a binary register 15 prior to its entry into a print out. If for any reason an anomaly cannot be recorded as register 15 full up, a lost message counter 19 is incremented. A maximum of three anomalies per call may be recorded.

Title: Improvements in and relating to automatically reclosing circuitbreaker systems for use on electric railways
IPC: B60L3/06
Filed: 1933-10-19
Abstract: 419,630. Protective cut-out systems. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Allgemeine Elektricitõts-Ges. ; 2, Friedrich Karl-Ufer, Berlin.) Oct. 19, 1933, No. 28975. Convention date, Oct. 19, 1932. [Class 38 (v).] An arrangement for automatically restoring, after a fault, a section of an electric railway utilizes a testing resistance SW, which reduces the fault-current to a harmless value, but allows enough current to admit of starting the trains, assuming no short-circuit exists on the system. Thus, on short-circuit, the current fluctuations which occur on trying to start a train do not perceptibly influence the limited, constant, short-circuit current, but if the latter has disappeared, the starting of trains produces large fluctuations of current in the testing- resistance circuit, which fluctuations energize the secondary of a current transformer ST. The section S is connected to a D.C. source through switches 1, 2 such that 1 opens on overload and opens at back contacts the holding coil 2h of the switch 2, so that the latter also opens. Circuit is made over back contacts of both switches 1, 2 for a relay ER which closes the circuit of the closing coil 1e through the contacts of a time-delay-relay R2, whereby 1 recloses and energizes time-delay relay R3 and, 2 being still open owing to the circuit of 2e being broken at R3, a testing current is passed through SW and ST to the section S. This current energizes R2 which, if there is a shortcircuit on the section so that R1 does not operate, closes after a delay of (say) 20 seconds a short-circuit about the coil 1h, so that 1 reopens and the section is permanently disconnected. At the same time R2 is locked closed at V and its contacts break the circuit of 1e so that 1 cannot be reclosed ; an indicator FR is also operated. If, however, when the testing current is applied, the short-circuit has been removed, fluctuations of testing current due to starting trains will operate R1 (which restores with a time-lag) so that R2 is constantly short-circuited and returns to its original position without closing its contacts. Therefore, the relay R3, which has a longer time-lag than R2, reaches its closed position and energizes the coil 2e to reclose 2 and render R1, R2 ineffective.
