Title: Electronic switching for counters
IPC: H03K3/30
Filed: 1966-04-21
Abstract: 1,139,262. Electronic counters. GENERAL TIME CORP. 21 April, 1966 [10 May, 1965], No. 17536/66. Heading G4A. [Also in Division H3] In an electronic variable-modulus counter of the type in which a magnetic core is gradually saturated by input pulses, a last pulse saturating the core which is then reset, producing a single output pulse, the counter 40 is switched " on " or " off " by rendering a transistor Q12, connected in the input circuit, conductive or non-conductive. The transistor Q12 may be controlled by a standard flip-flop or by the switch circuit 50 as shown, in which an " ON " pulse at terminal 54 turns on transistor Q13 which turns on transistor Q14 which in turn keeps transistor Q13 in the conductive state until an " OFF " pulse is applied to terminal 56. While transistor Q14 conducts, it turns on transistor Q12 to effectively apply input pulses, applied to a winding N4, to the collector and base of transistor Q10, which is itself turned on, so that the input pulses are applied to a winding N5 to gradually saturate the core 42 of the counter. The voltage applied to winding N5 is produced by a variable generator (Fig. 1, not shown) so that the modulus of the counter may be changed by altering the voltage-second content of each input pulse applied to winding N5, and hence alter the number of input pulses required to completely saturate the core of the counter. With the flip-flop or circuit 50 in the " OFF " state, transistors Q12, Q10 are both switched off so that input pulses are not applied to winding N5. In a modification (Fig. 3, not shown) the input pulses are not applied directly to the counter input winding (N9), but merely switch on a transistor (Q22) connected in series with a second transistor (Q23) controlled by the flipflop or switch circuit. When both transistors (Q22, Q23) are switched on, another transistor (Q21) is in turn switched on to apply input pulses to the input winding (N9).

Title: Improvements in telephone systems
IPC: H04Q3/00
Filed: 1947-07-04
Abstract: 636,138. Automatic exchange systems. GENERAL ELECTRIC CO., Ltd., and COLLYER, J. E. July 4, 1947, No. 17714. [Class 40 (iv)] An automatic exchange system provides facilities for a number of master stations to make direct calls through a smaller number of links with non-dialling selecting means to certain other subscribers, the links being distributed to calling master stations by a common allotting circuit. In the embodiment shown, two links, Figs. 5, 6 and 7, 8 respectively, are provided by which several master stations such as that in Fig. 1 may make direct calls to a maximum of 16 other subscribers. Each master station may make calls through its exchange line, Fig. 4, in the usual way. To make a direct call, the subscriber depresses one of a number of selector buttons (not shown), each of which operates a starting contact KA6 and a different combination of contacts KA2 to KA5, Fig. 1. Provided that the first link is free, KA6 operates relays T, M. M locks up in series with slow-operating relay E and operates relay N to prevent another subscriber from seizing the link. Relay, T transfers the connections of the master station from the line circuit to relay L, which operates and applies earth to the P wire in the final selector multiple. The operated contacts KA2 to KA5 energize corresponding relays A to D to apply earth to all the contacts of selector banks Z1, Z2, ZA1, ZA2 except those corresponding to the wanted subscriber, thus operating driving magnet Z which drives wipers Z1 to Z5 until they reach the wanted subscriber's position, when relay S energizes to cut the drive and operate relays' Rand J. R removes earth from the P wire to release the seized group selector while J locks T, completes a testing circuit for relay G and operates relay K, which transfers the selector start circuit to the second link. If the called subscriber is engaged, relay G operates to earth on the P wire to apply busy tone, but if the called subscriber is free, relay G remains unoperated and its circuit is disconnected by the relapse of relay S which also releases relay R, replaces earth on the P wire and operates relay H which connects the link to the wanted line and applies ringing current via relay F. The master subscriber then releases the selector button, allowing relays A to D, E, M, N to relapse. When the called subscriber removes his receiver, relay F operates, disconnecting the ringing current and completing the connection. Feed current is supplied through relay G, which now operates. Replacement of the master station instrument releases the link for further use. The caller may break into an existing conversation by closing a priority button KA1 to operate relay F. If the first link is engaged when the master subscriber presses his selecting button, relay TA operates instead of T and the caller is connected to the second link. If both links are engaged a signal may be given to any third caller by a lamp (not shown) controlled by relays J, JA.
