Title: Improvements relating to telephone systems
Inventor: CLARK RONALD ISAAC HERBERT
IPC: H04Q3/00
Filed: 1954-01-22
Abstract: 752,222. Automatic exchange systems. SIEMENS BROS., & CO., Ltd. Jan. 14, 1955 [Jan. 22, 1954], No. 2042/54. Class 40 (4). A bidirectional final selector which has certain levels allocated to party lines and others to individual lines and which has an auxiliary switch DS for choosing a ringing code is arranged always to receive three digits. In the case of a call to a party line the first and third digits set the selector and the second controls DS, whereas in the case of a call to an individual line the first digit is absorbed and the selector is set by the second and third digits. When the selector is raised by the first digit to a party line level, after the relapse of dialling relay C a circuit is made over vertical bank VBA and wire DLB for relay RL which connects up magnet DSM in place of vertical magnet V. At the end of the second digit, RL releases and connects up the normal change-over relay RD to direct the final digit to rotary magnet R. If the wanted line is free, test and switching relay H operates and code ringing takes place under the control of relay CR in accordance with the setting of the switch DS. If a party line serves 11 to 20 subscribers it is connected in two levels, and when the selector is raised to one of them a circuit is made over a second vertical bank VBB and wire DLC for advancing the switch DS to a subnormal position before it is stepped by the second digit. Alternatively, a different wiper of DS could be selected. When the selector is raised by the first digit to a level accommodating individual lines, a circuit is made over vertical bank VBA and wire DLA for relay OL which connects up release magnet Z. The wipers drop back and the selector responds to the subsequent digits in the usual manner. Provision is made for PBX hunting under the control of relay HS and wipers PB1, PB2, as described in Specification 203,759, [Class 40 (iv)]. If a PBX group occupies more than one level, the wipers are restored rotarily by magnet RZ on reaching the end of the level and are stepped upwardly to continue the search in the next level.

Title: Improvements in and relating to electric power converting apparatus
IPC: H02M7/51
Filed: 1932-01-26
Abstract: 395,425. Converting. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Fitzgerald, A. S. ; Warwick Road, Wynnewood, Pennsylvania, U.S.A.) Jan. 26, 1932, No. 2388. Convention date, Jan. 26, 1931. [Class 38 (ii)..] In an arrangement for transmitting power from a D.C. source 10 to an A.C. load 11 and comprising a pair of grid-controlled valves 16, 17 associated with resonant circuits comprising condensers 12, 13 and an inductive winding 15 to form a series-type inverter operating as described in Specification 347,474, means are provided whereby any change in frequency in the A.C. circuit as determined by the frequency of supply to the grid transformer 20 is followed by a corresponding adjustment of the natural frequency of the resonant circuits. The Specification explains that in such an arrangement as that described, current of sinusoidal wave form is produced in the load circuit only when the frequency corresponds to the natural frequency of the resonant circuits, and that the distortion in wave form produced when the two frequencies diverge is used to produce voltage impulses in the primary of a transformer 32 which impulses bear a particular phase relationship to the voltage across a resistance 30 when the frequency of the resonant circuits is below that of the A.C. circuit and are of opposite phase when the frequency of the resonant circuits is above that of the A.C. circuit. The transformer 32 is used to energize the grids of a pair of valves 28, 29, the plate circuits of which include the operating coils 35, 36 of a reversing switch 37 and' are connected across the resistance 30. Thus one or other of the valves 28, 29 is rendered conductive in response to frequency divergence, and the switch 37 is operated to energize the armature circuit of a motor 26 which is thus caused to operate in the appropriate direction to increase or decrease the air gap in the core of winding 15 so as to bring the natural frequency of the resonant circuits into agreement with that of the A.C. circuit. A modification is described, Fig. 2 (not shown), in which the motor is provided with two opposed field windings, one permanently energized together with the armature so that the motor tends to run in one direction but is caused to operate in the opposite direction by energization of the other winding in response to divergence in frequencies in the same sense as the divergence. caused by energization of the first winding.
