Abstract

379,533. Frequency changing ; comutator switching arrangements. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and HUMPHRIES, H. E., 61, Woodville Road, Blackheath, both in London. Sept. 25, 1931, No. 26789. [Class 38 (ii).] An arrangement for supplying reduced frequency impulses as compared with control impulses comprises a pair of solenoid relays R and S each having two windings and whose armatures Y, S, which remain in the position to which they were last moved, each controls the circuits of the other relay, the control impulses being applied to each of the relays successively so that impulses of reduced frequency are produced in a crcuit SM by the operation of an armature k1 which may be controlled by the relay S. A.C. impulses are applied to two windings of a polarized relay J the armature j1 of which connects a D.C. source to the relays R and S successively, a further polarized relay K also having two windings in parallel with those of the relay S being provided to operate the contact k1 for the magnet SM which may be the operating coil of a telephone step-by-step switch or of other periodically excited apparatus. Alternate control impulses energize one or other of the windings S (I), S (II) and K (I), K (II), to operate the armature k1 either to energize or de-energize the magnet SM so that impulses of half the control frequency are produced in the circuit of the magnet SM. The armatures r, s, prepare circuits for the windings I or II of the relays R, S, and K which are energized on the next operation of the armature jl. The arrangement may be used for halving the frequency of a pulsating direct current in which case an ordinary relay J responds to each pulse to operate one of the relays R or S, the other being operated on termination of the pulse. The contacts j1 may be those of a mechanical or other interrupter and the armature k1 may operate a further pair of relays such as R and S so as to produce impulses of one quarter or one eighth &c. of the control frequency.
