Title: Improvements in or relating to automatic switches for use in telephone or like systems
IPC: H04Q3/00
Filed: 1931-01-14
Abstract: 370,960. Automatic exchange systems. AUTOMATIC ELECTRIC CO., Ltd., (formerly AUTOMATIC TELEPHONE MANUFACTURING CO., Ltd.), Strowger Works, and TAYLOR, R., 30, Oulton Road, Wavertree, both in Liverpool. Jan. 14, 1931, No. 1340. [Class 40 (iv).] In order to economize in the use of relays in a group selector, the relay which controls the initiation of the hunting apparatus and interacts with the hunting magnet to produce stepping is rendered slow-to-release during the directive movement by means of a second winding which is short-circuited over operated contacts of the relay and contacts which are opened at the commencement of hunting. When the switch is seized, line relay A operates relay B which earths the release conductor 12 and prepares the circuits of stepping magnets VM, RM. Upon reception of impulses, relay A impulses magnet VM and relay C in parallel, the relay C being maintained operated during vertical stepping through the circuit of its lower winding closed at its own contact c1 and rotary off normal contacts NR1. At the conclusion of impulsing, C releases and com. pletes the circuit of rotary magnet RM which steps the wiper into the bank. As soon as rotary movement commences contacts NR1 open the short-circuit of relay C and at springs NR2 prepare of circuit relay C over the test wiper P. Hunting action is then produced by interaction of relay C and magnet RM until when a free outlet is found C fails to operate and rotary movement ceases. Relay H is operated when a free line is encountered to extend. the speaking leads 10, 11. and open the impulsing and rotary magnet circuits. In the event that all the outlets of a selected level are busy, the wipers are rotated to the eleventh position in which cam springs S1 prepare the holding circuit for relay B and springs S2 operate an overflow meter OVF. Furthermore busy tone and flash battery over lead 17, are connected by springs S3 over relay A, the line wipers in their extreme position encountering the bank contacts 15, 16 to provide a circuit over the relay and operated contacts h5, h6 to the calling party.

Motor control systems; travelling a fixed distance.- In step-by-step follow-up control of a master switch and a follow-up switch, the followup switch has two groups of contacts co-operating with terminals of two circuits associated with a cut-off switch and a reversing switch. whereby the motor is enabled to make step-bystep forward and backward movements and to stop in positions corresponding to given forward and hackward settings of the master controller. The invention may constitute a modification of the follow-up control systems described in Specifications 175,877 and 211,705. The arrangement shown in Fig. 1 comprises a motor 5, a master controller 1, and a follow-up switch 2. The hight-hand group of contact segments on the follow-up switch co-operate with terminals in a circuit containing an electromagnet 14 whereby control current is cut off from the motor 5 at positions corresponding to given forward settings of the master controller in a manner similar to the systems referred to above. The left-hand group of contact segments, connected together by a conductor 17, co-operate with terminals in a circuit containing an electromagnet 7 whereby the motor is reversed and caused to stop in given positions. The two groups of terminals are controlled in common, either, as in the Figure, bv relays in the lines 22 running from the terminals of the master controller, or, alternatively are directly connected in common to the master controller terminals. In a modification the two groups of contact segments are so arranged, that the follow-up switch first overruns a given backward setting and immediately, afbedwards returns and stops at a position determined by the forward group. The backward group of contact segments, in this later arrangement, are disposed as short detached extensions of the forward group. A motor controlled according to the invention may be used for operating the main controller of an electric locomotive.
