Title: Signalling system for automatic telephone exchanges
IPC: H04Q3/00
Filed: 1958-10-03
Abstract: 890,860. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. Oct. 3, 1958 [Oct. 10, 1957], No. 31669/58. Class 40 (4). Digits are sent from a subscriber's substation as a combination of at least one audio-frequency signal and a signal outside the audio-frequency range. Digits may be characterized by oneout-of-five audio-frequencies in combination with one-out-of-two loop impedances, or by oneout-of-ten audio-frequencies or two-out-of-five audio-frequencies and a particular loop impedance characteristic of digit transmission, or by one-out-of-five audio-frequencies and oneout-of-two frequencies outside the audio-range. The use of a non-audio component in digit transmission protects the digit receiver from spurious operation. As shown in Fig. 1, keys 1 to 5 in a group A each operate a contact particular to the key and a contact A common to the group A to give one loop impedance and five possible frequencies by tapping from an inductor D in a transistor oscillator. A Graetz bridge G in the supply to the oscillator protects the oscillator from reversal of current in the loop. Keys 6 to 0 in a group B each operate a contact particular to the key and a contact B common to the group B to give a second loop impedance and the same choice of five frequencies as with group A. At the exchange, shown in Fig. 2, relay N responds to the loop which holds up relays A and B against the action of bias windings. With a B-group key operated, the loop current decreases and relay B releases to connect filters F1 to F5 to the register over one set of contacts. With an A- group key operated, the loop current is decreased considerably and both relays A and B release to connect the filters to the register over a second set of contacts. The changes in loop impedance may be converted into tone signals for transmission over a trunk line by causing relays A and B to connect up one or other of two oscillators, see Fig. 3 (not shown). In an alternative embodiment shown in Fig. 4, each digit is sent as the combination of an audiofrequency, selected by the keys 1 to 5 and 0 to 6 in groups A and B in the circuit of one transistor oscillator, and a frequency above the audio-range selected by contacts A and B common to the keys in groups A and B and in the circuit of a second transistor oscillator. A contact AB common to all keys disconnects the microphone. In this embodiment seven filters are needed at the exchange to route digits to the register, see Fig. 5 (not shown).

Title: Improved means for address-selection of devices
IPC: H04Q3/00
Filed: 1963-08-13
Abstract: 1,057,381. Automatic exchange systems. SIEMENS & HALSKE A.G. Aug. 13, 1963 [Aug. 16, 1962], No. 31944/63. Heading H4K. [Also in Division G4] A number of devices in a multi co-ordinate array may be selected simultaneously provided that the addresses of the devices to be selected do not differ by more than one word. Thus in a telephone system comprising a plurality of selector frames Z1 to Z3 each consisting of a number of cross-coil switches x, y, to x 4  Y 4  and a central store W into storage sections BW of which are placed three word addresses of switches to be operated, the sections BW are cyclically scanned and their contents are readout and placed into intermediate store H as long as each address differs from the previous one or ones in only one word. In respect of the first address the store H energizes one out of each of the three sets of relays X, Y, Z in order that the corresponding cross-coil switch may be selected. If it is assumed that the succeeding addresses differ only in the word corresponding to co-ordinate Z then the store H successively energizes the corresponding Z relays. The response time of the relays X, Y, Z and the cross-coil switches is much longer than that of the sampling time for any one of the storage sections BW so that in effect a plurality of cross-coil switches are operated simultaneously. Consequently the selection time is materially reduced without increasing the possibility of a false connection due to multiple marking. The words are written in binary 1 out of n code e.g. the word for selecting a Z relay is a " one bit " in one of the three possible positions for the bits. The comparators Vx, Vy, Vz compare the address(es) already in store H with the next one in the output register ZW of the store section BW. Provided one of the AND gates Kxy, Kyz, Kxz conducts thereby indicating coincidence of words in two of the comparators, inhibit gate 1G is blocked and the new address can be written into store H. If there is no coincidence, an output from the Z portion of store H is passed via OR gate M and gate 1G to the blocking inputs of gates G1 to G11. Store H can hold up to four addresses differing only in the X or Y word or up to three addresses for differences only in the Z word. Counter Q or timer T automatically inhibit further input to H when the latter is full, The store H may comprise monostable or bi stable circuits. The devices in the array may be magnetic ring cores.

Filed: 1947-12-05
Abstract: 640,961. Knitting-machines; stop-motions. BERRIDGE & CO., Ltd., I. L., MARTIN, C. S., and COOKE, A. E. Dec. 5, 1947, No. 32101. [Class 74 (ii)] The fault detector in a stop-motion for a knitting-machine of other machine operating upon a yarn or yarns comprises a device which reacts to breakage, slackness or undue tension in a yarn. The yarn T runs between two series of pivoted intercalating fingers 1, 2, pivoted at 3 and 4 respectively, the fingers 2 being spring- biassed by an adjustable coil-spring 12 to enter between the fingers 1. Undue yarn tension depresses the fingers 2 and permits the yarn to slide over their knee portions 7a, to be discharged from the device. The absence or slackness of the yarn allows the fingers 1 to fall through the fingers 2 when an arm 11 extending from the pivot 3 operates known devices to stop the machine. The device shown is threaded from underneath but may also be adapted for threading from above. Only the two outer fingers of the series 2 need be bent to support the yarn, the remainder being bent as at 7b.

Abstract: 522,046. Braiding-machines ; looms. HODGES, P. Dec. 5, 1938, No. 32158. [Class 74 (i)] [Also in Group IX] In a circular loom or braiding-machine the thread supply carrying member is driven by a permanent magnetic field and the threads among which the former threads are driven pass through an air gap located in the field. The drive is transmitted from the inner rotating member 16 of the machine to the carriers 18 of the inner bobbins by magnetic force, there being no physical connection between the parts 16, 18. The threads from the outer bobbins 10 can freely pass through an unobstructed air gap 23 when moving across the threads of the inner bobbins at the inner side. In one arrangement permanent magnets 24, 25 are placed at intervals around turrets 16, 12, which rotate in opposite directions, the mutual attraction causing the bobbins 19 to travel round with turret 16. In another form, the magnets 25 are replaced by pieces of soft iron formed or provided on the inner sides or faces of the bobbin carriers 18, or soft iron may be provided on the central driver and magnets on the bobbin carriers. Slots 21 may be deflected by plates 22, 27 or in any other suitable way. It is stated in the provisional Specification that the use of a ball race between co-operating faces of relatively rotatable or traversable members at least one of which is interrupted or divided in its length is a feature of the invention. Specifications 227,011, [Class 74 (i)], and 487,202, [Group IX],. are referred to.

[Also in Group XL (b)] Waveguides are used for transmission and switching in an exchange. An electric selector comprises two Eo1-Ho1 transformers linked by a common circular waveguide LG so that one inlet consisting of a rectangular waveguide IG has access to a number of rectangular waveguide outlets OG. The outlets are controlled by electromagnetically controlled mechanical shutters SH, by gas discharge tubes in the guides or by gyrators. If the switching elements are omitted, the transformers provide multiple connections. A number of shuttered guides may be provided at each end of a common guide to provide a line finder/final selector link. An exchange comprises subscribers SUB1, SUB2, Fig. 10, multipled by elements M and compensating elements CE to line under/final selector links LF1/FS1 and LF2/FS2. There are separate channels for sending and receiving and each line circuit LC1, LC2 includes a hybrid transformer. The system may be made bothway by simple time division of the carrier. Signals are transmitted by amplitude modulation or by pulse repetition frequency modulation. The shutter pattern for routing a call is set up by an electronic common control not described. A distributer which can be used as a selector in a system using frequency selection, comprises a waveguide LG, Fig. 11, and a series of junctions each consisting of a resonant slot and a reflecting ring, the slots RCS1, RCS2, RCS3 and the rings RR1, RR2, RR3 being respectively tuned to carriers f1, f2, f3. An outlet is selected by selecting one of the carriers which is accepted only by its own tuned outlet. The arrangement is shown symbolically in Fig. 12. A reflex klystron is used to generate the carrier, the frequency being determined by the reflex cathode voltage. Signals are transmitted by frequency modulation. Two switching stages in a frequency selection system are shown in Fig. 13. The carrier f1 characteristic of selector D1 is demodulated at BD1 and in a manner not described, causes another carrier f2 dependent upon the route to be set up, to be transmitted and modulated at AD1. At the same time DD1 returns carrier f1 to the previous stage. The carrier f2 is demodulated by DD2 in selector D2 and, as before, another carrier is transmitted forward and modulated by AD2. Carrier f2, modulated with the backward signals received by CD2 is returned by DD2 to CD1 in selector D1. The signals are repeated by DD1 on carrier f1. A subscriber may be multipled to a number of line finders and to a number of final selectors. The waveguides may be printed or may be dielectric waveguides in which case metal may be eliminated from the speech path. Reference has been directed by the Comptroller to Specification 733,486, [Group XL (b)].
