Title: Improvements in or relating to party-line telephone systems
IPC: H04Q5/00
Filed: 1945-11-23
Abstract: 602,214. Party-line systems. STANDARD TELEPHONES & CABLES, Ltd., and ELLIOTT, T. W. Nov. 23, 1945, No. 31651. [Class 40 (iv)] A party-line system comprises a uni-directional repeatered loop. The system described constitutes a service engineer's circuit between attended main and unattended auxiliary repeater stations along a coaxial cable and is carried by an interstitial quad within the cable. As shown in Fig. 2, the upper pair is repeatered in a west-east direction and the lower pair in an east-west direction, all speech currents passing through a looping pad at the west terminal. Repeaters are placed at all main and some auxiliary stations. All signalling currents are sent over the phantom and byepass the repeaters. The telephone transmitters are transformer coupled through suitable pads to the lower side of the loop and the receivers are similarly coupled to the upper side, the arrangement being reversed only at the west'terminal to avoid side-tone. Since at repeatered stations the receivers and transmitters are coupled respectively to the output and input of the repeaters, the equalization incorporated therein compensates in the upper arm of the loop for the preceding length of cable and in the lower arm of the loop for the succeeding length of cable. Calls are set up by a control station, either the east or the west terminal, which is called by 17 c.p.s. ringing over the phantom, and from which the required station may be selectively called in the manner of a standard train despatching system such as described in Specification 526,828, by impulses over the phantom. Parties temporarily located at an auxiliary station are called by 17 c.p.s. ringing. The repeaters may be provided with power from the repeater of the coaxial system proper, which may in turn be supplied with 50-cycle power over the coaxial cable itself. In the event of a power failure, arrangements are provided to switch out the service circuit repeaters and to provide a through speech path.

Title: Improvements in electrical signalling systems
IPC: B66B19/06
Filed: 1937-11-20
Abstract: 506,008. Electric signalling systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and HITCHEN, H. Nov. 20, 1937, No. 32000. [Class 40 (i)] In a bare wire signalling system for use in rope haulage systems in mines of the type wherein signals for starting and stopping the haulage engine are produced by connecting together the bare resistance wires 10, 11 and automatically balancing the resistance inserted by resistances controlled by an automatically - operated stepping switch W to indicate the location of the signalling point, the resistance of the point of contact of the wires is excludedfrom the signalling circuit so as to prevent false signals due to a poor contact. This is accomplished by including in the signalling circuit only the wire 11 of the pair 10, 11, the circuit being completed by an insulated wire 12 or an earth return and the wire 10 being used merely for applying battery potential to the circuit. When the wires 10, 11 are connected together for a predetermined time, relays L, BR, and slowacting relay TD pull up to close a self-stopping circuit for the stepping magnet WM of the switch W which varies the resistance connected to the bank contacts until the operation of the relay. BR is neutralized over its second winding. Release of the relay BR operates locking relay MW which completes the indicating circuit over a further switch wiper (not shown). Bells located at the various signalling positions may be operated over a two-wire lead by short pulses applied to the relay L. A single bell-lead including the bells in series may be provided, the supply to the lead being obtained from the lead 10. A motor driven switch having wipers which contact directly with the balancing resistance may be employed instead of the stepping switch. In a modification a single-winding relay, BR may be switched into the diagonal of a Wheatstone bridge circuit when a signal is transmitted. In a further modification, the relay BR may be operated to stop rotation of the switch W instead of being released. Specification 479,884 is referred to.
