Title: Improvements in telephone systems
IPC: H04Q3/00
Filed: 1926-09-14
Abstract: 282,153. Standard Telephones & Cables, Ltd., and Haigh, L. B. Sept. 14, 1926. Automatic and semi-automatic exchange systems.-In a system in which an operator can offer a trunk call to a busy subscriber, the connector over which the call is offered is of the type employed in the establishment of ordinary connections without any additional apparatus, the change-over relay being energized over a fourth wire to switch the connection through. Setting up connection. Relays A and B operate and prepare an impulsing circuit for the vertical magnet V and a relay C in parallel. After the " tens " impulses have finished, relay C deenergizes. and the " units " impulses operate the rotary magnet R and a slow relay E in parallel. If the subscriber is busy, relay G energizes over its winding (4, 3), E (8, 6), P, and operates its fly contacts 5, 6. When E relapses, G fully operates [battery, G (4, 3), E (8, 7), G (5, 6), G (2, 1), H (25, 26), B (8, 9), earth], opening the rotary impulsing circuit at G (7, 8), and substituting busy flash for earth on the (4, 3) winding of relay A, and connects " busy hold " to B (4, 3) at G (10, 11). When the subscriber hangs up, relays A, B, G release in turn, and a circuit [ground, A (6, 5), B (6, 5), N (2, 1), Z to battery] is closed for the release magnet Z. If the line is free, when E releases, the test relay H energizes in two stages. Ringing-current and ring-back tone are now sent. When the called party answers, relay F pulls up in two stages and switches the wanted line through to the backbridge relay D to complete the talking circuit and send back the supervisory signal. When the calling party hangs up, relays A, B, H, F, D restore in turn and the release magnet Z operates to return the switch to normal. If the called party hangs up first, an alarm lamp LP will glow, and after a predetermined time an alarm will be given. When an operator calls. the operation of the switch is as above if the line is free, and if busy, the relay G operates as before. The trunk-offering group selector grounds its fourth wiper either under control of the operator, after busy tone has been received, or as soon as the connector is seized. Relay C now energizes over contacts G (16, 17), and closes a talking circuit over C (11, 12), G (18', 19), and C (13, 14), G (20, 21), the subscriber receiving feed from the connector to which be is already connected. The operator now offers the call in the usual manner.

Title: Improvements in brakes for vehicles
IPC: B60T13/74
Filed: 1945-09-05
Abstract: 598,617. Electrically and magnetically controlled brakes. SPENCER, T. D., and PATENT LIGHTING CO., Ltd. Sept. 5, 1945, No. 22905. [Class 103 (i)] [Also in Group XXXVII] Relates to an electrically propelled vehicle provided with means for regenerative braking for use at higher speeds and with friction braking for use at lower speeds, the friction braking being of the type in which the kinetic energy of the member to be braked is employed to apply the brakes by means of a coupling comprising two co-operating parts of an electro-niagnet assembly having controlled excitation, one part rotating with the member to be braked and the other capable of only a limited rotation. According to the invention means responsive to the vehicle speed are arranged to introduce a gap between the electro-magnet parts at high speeds and to eliminate the gap at low speeds. As shown, the friction brake comprises a brake band 12 mounted on a fixed backplate 13 and adapted to be expanded against a rotating drum 10, by a lug 16 on an electro-magnet core 14 capable of a small rotation co-operating with lugs secured to the brake band. Force is applied to the core 14 to apply the brakes by energising a winding 18, so, through friction face 21 coupling the core to an armature 19 rotating with the drum 10. At low speeds, when the brake is not applied, the armature 19 is lightly pressed against the core 14 by leaf springs 20, but at high speeds a gap sufficient to prevent operation of the friction brake despite full excitation of the winding 18 is introduced by movement of the armature 19. This movement is controlled through a linkage 32, 29, 30, 31 in response to axial movement of a collar 24 controlled by the centrifugal action of balls 27 held in tapering recesses 26 between the drum 10 and a member secured to the collar 24. Alternatively the speed responsive means may comprise a solenoid and plunger supplied with current through a speed responsive switch centrifugally operated (see Group XXXVII). The friction braking means may be controlled from the same handle as the regenerative braking means, and a relay associated with the regenerative braking means may be employed to permit application of the friction brake at any speed if the regenerative braking fails.
