Description

The proposed telephone set is designed to serve the dispatching telephone communication line and is intended to enable the dispatcher, located on one of the two-wire lines, to call his choice and speak with all points that are included in this line. At the same time, the total number of points that can be included in the same chain is 56, not counting the distribution point. The operation of the device is based on the fact that 56 different combinations of currents of both directions can be sent to the line from the control point, and each of these combinations has a working effect (ringing signal) in only one of 56 points, while in all the remaining 55 points the calling devices remain at rest. To obtain these 56 combinations from the currents of both directions, 4 different circuits were used, in each of which DC current could circulate, either in one direction or another. Two of these circuits participate in one of the linear wires and ground as a reverse drive; in the 3-E circuit both linear wires are involved (without earth, and finally, in the 4th circuit both wires connected together are the direct wire and the earth is reverse. Since a direct current can circulate in each of the four circuits of one direction or another, it only makes up -8 combinations from currents of both directions, and these combinations are hereinafter referred to as primary combinations of currents. These 8 primary combinations are combined in pairs with each other in the form of two consecutive combinations of currents, i.e. the line is first sent somehow bottom 8 combinations of these currents and then cocoa someday other seven others, so that in total 56 combinations obtained.

Pa figs. 1 of the drawing, a table 56 of current combinations is shown, and FIG. 2 and 3 schemes of the proposed telephone set.

Pa figs. 1 against the combination number, two current pulses are given and it is indicated which of the poles (-} - or -) of the DC power source, respectively, should be connected to both the linear wires and the ground 3- during the 1st current burst and during the 2nd . In the following, these 56 combinations are referred to as secondary current combinations. These latter are sent from the control point by means of a DC source (for example, a battery), the zero pole of which is connected to the line wires and to the ground, first in one combination, then in another, and the manipulator for this purpose can be hets consist of buttons, keys, etc.

Each of the 56 secondary combinations should have a working effect only in one of the 56 points, for which purpose these points are supplied with telephones. The scheme of which is given in FIG. 2, with the essential part of these devices, besides the usual microtelephone and induction coil, is their calling device, which contains two relays of the special device - i and jBj, as well as a battery bell 3 in, acting from the local battery B. 1gak from the circuit, bell 3 can only start working after contact 1 of the relay –B is closed, but in order for contact 1 to close, a preliminary release of the CD box of the R relay from under the hook hook K attached to the E channel of the E relay is required. Thus, for action ka 3 v it is necessary that, in a certain way, both the relays R and the relays e act. The main feature of these relays is that each of them works only from one of the above 8 primary combinations of currents and does not work from the other 7 primary combinations. For this, both relay R. and relay E contain one polarized electromagnet P and one neutral electromagnet H, and the CD or CDi measles are always attracted to the cores of the neutral electromagnet due to the N or N spring. Winding of each electromagnet divided into two halves, terminated by clips 1-8 and 9-16, serving to "paste each relay into one of

8 primary current combinations from which this relay should operate. "The setting consists, firstly, in a certain connection of the windings of the electromagnets P and H among themselves, and secondly, in a certain connection of these windings into the linear wires L and cTIg and earth, and according to the principle" you need to have two cases :

1) "tuning to the primary combination of currents, in which only one of the linear wires is utilized (there are four such combinations);

2) "setting for the primary combination of currents, in which both linear wires are utilized (there are also four such combinations). In the nerve case, the terminal connection is made so that

 the two halves of the polarized electromagnet P winding are in the post-helix connection, after which the resulting continuous winding is connected between the ground and one of the linear wires. Both halves should be. moreover, they are connected in such a way that the action of the current is added up and not destroyed each other depending on the wire that the atom will apply (i.e. JTi or JJz): and also depending on which of the ends of the resulting continuous winding connected to the wire and which to the ground; This relay will work only from one of the 4 primary combinations of currents in which one line wire is utilized, namely from the combination that corresponds to the setting made in relation to the wire and in relation to the current direction. Both halves of the neutral electromagnet H winding must also be connected in series with each other, after which the continuous winding turns on between the ground and that of the linear wires that remain free after the windings of the polarized electromagnet P are turned on (see above); and here both halves must be connected in such a way that the action of the current in them is formed, and not destroyed mutually. The purpose of the neutral electromagnet H is that, when excited, it fixes the relay in the normal position, which is indicated in FIG. 2. Investigator

AND

however, with a high primary current combination, in which both linear wires of the relay are utilized, "tuned to a combination in which only one of the linear wires is utilized will not work.

As for the second case, i.e. when "the relay must be tuned to such a primary combination of currents in which both linear wires are utilized, the terminals are connected so that each of the oCiMOTKH halves of the polarized electromagnet P is in series with one of the winding halves of the neutral electromagnet J9, after which results in two continuous windings, each of which is connected between the earth and the corresponding linear wire; it should be borne in mind that the circuit and the direction of the current, which are used in this primary combination. As a result, a relay “configured in this way will work only ot one of the 4 primary combinations of currents in which both linear wires are utilized, and from the primary combinations where only one linear wire is utilized, none of these relays will have . Thus, ultimately, after “tuning,” both relay D and relay Sj work only from one of the primary combinations, and the current lead l does not work from all the others.

If relay B and relay RI should be “not tuned to one of the 8 primary combinations of currents, but to different ones, then: the relay should be“ tuned to a combination that corresponds to the 1st current sending (Fig. 1), and relay R - on the combination that corresponds to the 2nd current premise; Therefore, the connection of all 16 terminals between themselves and with the linear wires and ground can be made in 56 different combinations, each of which corresponds to one of the secondary combinations of currents indicated in FIG. one.

By way of example, one of the combinations is given in FIG. 2, namely: the connection is made so that the working effect is obtained only from the combination of currents indicated in FIG. one

under JV 1, i.e., if, at the first current sending, the current source is connected to the wire L and its negative pole with the positive pole by its positive pole, and the current pole is connected to the ground and its negative pole during the second sending of current With the L- wire, with this combination of currents, the battery bell 3, shown in FIG. 2, will come into effect; for all the other 55 combinations of currents, the same 3-rd bell should remain at rest.

When the currents are sent for the first time (Fig. 2), the positive pole of the current source located at the connecting point (not shown in Fig. 2) will be connected to the JIj wire, and the negative pole will be connected to ground; consequently, nz wire L current will go to the terminal 1 - the upper winding of a polarized electromagnet P relay 1-terminal 2-terminal 3-lower winding of the same electromagnet P relay RI terminal 4 terminal 16-right winding polarized electromagnet P relay R- terminal 15-terminal 14-left winding of the same electromagnet P relay B-terminal 13-ground. As a result, the current will flow through the successively interconnected windings of the polarized electromagnet P relay B and through the interconnected windings of the polarized electromagnet P relay JS; the windings of the neutral electromagnets H of both relays. and B will remain without current. In this case, however, the windings of electromagnet P, relay B, will flow in one direction, and on the windings of electromagnet P, relay B, in the other, directly opposite, so that ultimately only one of the relays will work — in terms of winding conditions — relay B, while time, as relay B will remain at rest. Thus, the first sending of current will result in the attraction of the core (relay i to the cores of the electromagnet P of this relay, and the attraction of the core will, in turn, result in the release of the core CD from the locking hook K.) Then, the second sending will follow current during which the positive pole

the current source will be connected to the ground, and its negative pole with the wire L therefore, from the ground (Fig. 2) the current will go to terminal 13 - the left winding of a polarized electromagnet P relay R-terminal 14 terminal 15-right winding of the electromagnet 2Z relay R-terminal 16-terminal 4- the lower winding of the electromagnet 17 relay E-terminal 3-terminal 2-upper. Winding of the electromagnet P relay RI-terminal 1-wire L-. As a result, the current will pass through the windings of the polarized electromagnet II of the relay R connected in series and the windings of the polarized electromagnet connected in series between the relays P of the R {windings of the neutral electromagnets of both the R and R relays without current. In this case, for the same reason that was mentioned above, only one of the relays will work, in this case, the R relay, since the current now has the opposite direction. Consequently, the measles CD will begin to be attracted to the cores of the electromagnet II of the relay R, and the measles will begin at the same time to return to their original position, which is indicated in FIG. 2, in which it is not expected that during the short-term gap between the first sending of current and the second sending, measles will not have time to return to its original position, i.e. Do not brake with its locking hook. To the CD box of the R relay,: The CD measles will continue its movement and close contact 1, and the hook To its rounded edge will rest against the end of the CD box. Since contact 1 participates in the local circuit of bell 3, this latter will take effect, with which, therefore, the desired operating effect, which will be obtained by nrodol, will be pressed until the current combination circulates in the line when the second message is circulated such. After the break of this combination, the measles VD of the relay R will return to the normal position due to the spring iV, and at the same time the measles will take its initial position, i.e. hook K again stops measles OD, as shown in FIG. 2

With all the other 55 secondary combinations of currents, the call bell cannot be received in the apnarata in question, as can be seen from the analysis of these combinations (Fig. 1): if you take, for example, the secondary combination under 16, 23, 30, 37; 44 or 51, then in all these cases the second sending of currents corresponds to the same second sending under jYs 1, i.e. the relay R (Fig. 2) should have worked, but in fact this cannot happen, since the nerve sending currents that corresponds to the listed JV ° No. 2 secondary combinations is different from the same nerve sending under L 1; Consequently, in all these cases, the relay R does not work when the currents are first sent, and the measles CD relay R does not free from the locking hook K. For all the other secondary combinations (Fig. 1), the second sending of currents differs from that of L 1, and therefore, the relay R cannot work, pin 1 does not close and the ringing bell will not follow. By the same method, the operation of the device can be tested by “adjusting it to any of the 56 secondary combinations of currents.

From the above, the following can be seen: the action of the proposed telephone apparatus is based on the fact that 56 different combinations of currents of both directions can be sent to the forwarding point, each of which consists of two consecutive sendings of current of one or the other direction to one of the four x penalties listed above; Each of the 56 items included in the common line is supplied with a telephone set, the calling part of which contains two relays, each of which acts only on the current of a certain direction sent to one of the above 4 circuits, and the action of both relays is mechanically between is connected in such a way that the operating effect (closure of contact 1), the realization of which is achieved by the operation of one of the relays, can be followed only after the preliminary operation of the other relay.

Pa figs. B shows another version of the apparatus.

it is also based on the fact that 56 different combinations of currents of both directions can be sent to the line from the control point, according to the method shown in FIG. 1. The design of the telephone apparatus is basically the same, being installed on each of the 56 points, with the same design, which has already been described above and is shown in FIG. 2: the calling part of the apparatus (FIG. 3) and in this case comprises two relays B and E of the above device, as well as a 3-volt battery bell acting on the local battery B. Here, however, the operation of both relays is not mechanically interconnected This is so that the closure of contact 1, which is involved in the local circuit of bell 3, requires the prior action of the relay -K, but for the implementation of the operating effect, i.e. The operation of the battery bell 3 # still requires that relay E is pre-activated. -In fact: when relay R (Fig. 3) closes, contact 1, so that the current from the local battery B goes to the spring L -contact I-external winding of the battery ring Sound to the other pole of battery B on the other hand, from a contact 1 current is still in the spring N- - contact II - measles I battery battery 3 in, contact III-internal winding of the call, to the other pole of the battery; since through the windings of the battery bell 3 into the current will pass in the opposite direction, this bell will remain at rest. Therefore, when the contact I of the relay closes, B, the bell does not start the operation of Sv. For this, as in the previous version, the preliminary operation of the relay R is required, namely: when the relay E under the action of the first sending of currents from the corresponding secondary combination works,. Then the first consequence of this Wits is the interruption of the contact P. Then, under the influence of the second sending of currents, relay B will act, and it is assumed that contact I will have time to close before the interrupted contact II is restored. As soon as contact I closes, the current from the local battery B goes to the spring. N-contact I-external winding of the battery bell Sound to the other pole of battery B through the internal winding of bell 3 into the current now the NS passes, as the contact is interrupted. P. Consequently, the measles of call 3 in the headpiece are attracted, and at the same time the contact of IE is interrupted. The interruption of this contact has the meaning that, in the future, when the interrupted contact II has already been restored, the measles of call 3 can not be restored to the normal position, shown in Fig. 3, until contact I is closed. Thus, being removed from the position indicated in FIG. 3, the measles I will continue to be attracted to the cores of my electromagnet and close contact IV, and the inner winding of the bell will again be under the current, the direction of which is directly opposite to the direction of the current under which the outer winding is located. As a result, the measles I will begin to move away from the cores of the electromagnet, contact IV will be interrupted, and only the external winding will be energized; measles I am again a petition, contact IV is closed again, etc. In other words: if the secondary combination of currents sent to the line is such that when the first current is sent, relay 1 will work, and when the second message is sent, relay E, then ultimately the desired working effect is obtained, i.e. ring bell in one of 56 points. In all the other 55 points, the 3tf battery calls will remain at rest on the same grounds as were described in the description of the previous version.

Thus, a common feature of both options is: first, the operation through 56 combinations of currents of both directions and, secondly, the implementation of the working effect during the coordinated operation of two relays of a special device operating in a certain order one after another; both options are different in that in one of them both relays are mechanically connected, and in the other, electrically.
