Abstract

990,601. Automatic exchange systems. ERICSSON TELEPHONES Ltd. Jan. 22, 1964 [Feb. 7, 1963], No. 5112/63. Heading H4K. Apparatus for determining a calling subscriber's number comprises a row of magnetic cores C10 ... C19, C20 ... C29, C30 ... C39 for each digit, one core in each row being threaded by a conductor such as 11, 12 individual to each subscriber. Each conductor also passes through a start core CS. If the number is in code form, each conductor may thread more than one core in a row. A storage matrix consists of three sets of cores SC shown vertically which are connected in sequence by an input control IPC and transfer their numbers when required to a register RG under the influence of a read-out control ROC. When a call is initiated a current pulse is produced in the relevant conductor such as 11, 12 by the discharge of a condenser, Fig. 2 (not shown), or by the charging of a condenser, and as a result output pulses pass from the energized cores through amplifiers to IPC and to the storage matrix.
