Title: Improvements in or relating to electric selecting circuits
IPC: H04Q3/42
Filed: 1947-06-19
Abstract: 655,941. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. June 19, 1947, No. 16203. Convention date, Nov. 6, 1945. [Class 40 (iv)] A selector which has its outlets marked by different potentials is controlled by a plurality of relays which respond in different combinations according to the selector terminals engaged. In Fig. 1, relays A, B respond to potential differences of u, 2u, respectively, where u is the voltage of each of the batteries shown. When the number of the terminal Sa1-Sa5 closed by the directing device O is that of the selector terminal 1-5 engaged by the wiper F, relay A alone operates to release the drive magnet R and to operate slow-acting relay C. In any other case, either no relay operates or both relays A, B operate to maintain the drive magnet. In Fig. 2, the number of wires between the director and the selector is reduced to two. Relays A, B, when energized over their left-hand windings, respond to potentials of 2u, 3u, respectively, while if energized over both windings, they respond to u, 2u, respectively. If director contacts Sa1, Sb1, Sc1 are closed, when the selector wiper touches terminal 1, relay B energizes alone to stop the magnet R and energize relay C. For any other director contacts, when the wiper reaches the corresponding selector terminal, relay A alone operates to stop the selector switch and to operate C. Whenever the wiper contact is not equivalent to the director contact, no relay or both relays A, B operate and the drive magnet R remains energized. In Fig. 3, the number of selector positions is doubled by applying the same D.C. potential to a pair of adjacent terminals, the second of which is also subjected to an A.C. potential. The relays A, B, of the type used in Fig. 2, respond to the D.C. components and a relay D in a rectifier bridge responds to the A.C. components, the drive magnet R and the slow-acting relay C being controlled by all three relays A, B, D, according to the director contacts Sb1-Sb12, Sc1-Sc12, Sd1-Sd12 closed. In Fig. 4, the selector positions are arranged in groups of ten, a group being selected in any of the ways already described, whereupon contact a1 opens to deenergize the drive magnet. The selector is then directed to the required unit by a series of impulses over contact i. Specification 617,100 is referred to.
