摘要： 1,147,426. Automatic exchange systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 9 June, 1967 [23 June, 1966], No. 28196/66. Heading H4K. In a scanning arrangement for detecting a circuit in a distinctive condition, e.g. a calling line circuit, and recording its identity, two scanners are provided and the stand-by scanner is rendered operative by the identity signals to perform a check on the circuit found by the working scanner and to give a fault signal if the identity is not confirmed. The scanners normally exchange their working and stand-by roles at the end of each scanning cycle, but the stand-by scanner is able to time out the working scanner if no end-of-scan signal is forthcoming, and a fault signal is given if the same scanner is timed out in two successive cycles. The arrangement described is based on that of Specification 946,840 in which scanning stops when a calling line is found and continues after connection is made to a register, a fault condition being set up if this does not occur within a certain time. Calling and " park " gates of pulse-plus-bias form are associated with each line circuit in order to detect a PG or permanent calling condition, a persistence check being performed when a marking is found on a park gate.

摘要： 1,125,375. Automatic exchange equipment. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 29 Dec., 1966 [24 Jan., 1966], No. 3133/66. Heading H4K. A register for use in a telephone system comprises reed relays, such as XYWZ, which lock up or stay back according to whether a binary mark is or is not present on an input, such as lead d associated with relay Z; those energised relays of a register priming associated gates, such as GIC for relay Z, over which gates the registered word may be read out non- destructively. To seize a register group a lead B is marked to operate relay H and connect common lead OHL to earth over rectifier HD. To write a word into the register, marks are applied to the appropriate leads d, transistors such as TR4 conducting to connect earth to the corresponding relays which lock up to 24 volts negative over a resistor r on one side and to 24 volts positive on OHL derived from transistor TR2 switched on by TR1 which conducts in response to a write priming signal on lead A. To read out, the lead A is again primed to put 24 volts positive on the rail OHL, rectifiers MRO associated with operated relays being back biassed by the 24 volts negative over resistor r but those rectifiers MRO associated with unoperated relays transmitting the voltage to the associated gates GIC. When the gates GIC are interrogated by pulses on terminals p output appears on terminals OP only in respect of those gates conditioned by operated relays. To clear the register a signal on lead B causes TR5 to conduct so that a signal on lead C can cause TR3 to conduct. With both sides of the relays at earth locked up relays release. A second register with relays S and T is shown. Resistors RO simulate further relays in this register, simulated lock-up contacts CRO being operated when these binary bits are required to be read out.
