Description

The present invention relates to a device for synchronous transmission.

with contact arms continuously rotated by any engine, one at the transmitter and other

on the receiver. The invention aims to make the transmission more reliable by using in a series of circular contacts of the transmitter of a permanently closed contact, designed to close the circuit, through which electrical energy used in it to establish synchronism is transmitted to the receiver, which is achieved by varying the speed of rotation of the lever the receiver and it is ascertained that a fixed spark is obtained between the circular contacts of the receiver.

In the drawing, FIG. 1 shows a circuit diagram of a transmission device; FIG. 2 is a front view of the transmitter and FIG. Side view of it in the section.

To metal shaped box 34

(Fig. 2 and 3) a ring 11 of insulating material is attached, on which a series of contacts 12 are installed (eg one hundred). All these contacts, except for one (contact O, fig. 1), consists of two separate contact parts. In the center of the box 34 there is an axis 20 with a flange 3, on which, using a clock mechanism, 16 is in the plane of the ring. eleven

(do not touch it) a disk b, equipped with a ball bearing 4, can rotate. On the edge of the disk b there is a freely suspended contact 7 (Fig. 1), which, when the disk b is rotated, under the influence of centrifugal sIL1, comes in with pins 12 and slides on him. By the handle 46, which is mounted on the axis 20, the contact lever 22 can be rotated so that the contact 23 fixed at its end will interconnect the individual contact parts of any of the contacts 12. With the help. Since the proposed instrument is meant to transmit a direction (azimuth), then for this purpose it can be equipped with a dial 28 ,. the divisions on which are indicated by the arrow 2 &, fixed on the axis in one position with the lever 22, the rotation of the handle 46 can be realized manually and automatically. In the case of efficiency, the transmitter can be equipped with an arrow 29 speed counter. When the lever 22 passes the full circle, the counter will come into action and and the window 41 will turn on. For this, the end of the lever 22 has to be provided with a protrusion of the same shape as in the installation levers of the adding machine. The long counter indicates two digits of digits, for which in box 39 there are provided for two windows. The whole mechanism is attached to the box 34, which is screwed to the j

Cut the disk to contact 7, go out through the sleeve 37. Board 1 with the device, in fixed installations, can be attached to the shield. The receiver is different from the transmitter by the absence of the lever 22. In addition, each of the contacts 12 in the receiver is equipped with

 plate tips, and the space between its parts serves

; as a spark gap.

The transmitter is electrically connected to the receiver via a high frequency transformer (induction tube) (Fig. 1). . The voltage of the secondary circuit of the transformer is of the order of 3000-3500 volts. Thus, inductive coupling is established between the instruments, with the transmitter operating at low voltage (on the order of 30-50 volts) depending on the distance between the sending and receiving instruments and the mode

transformer primary winding. The fixed contacts 12 of the transmitter 9 are connected via a transformer to the sliding contactor 7 of the receiver 9, and the fixed contacts of the latter are connected to the sliding contact of the transmitter.

If the lever 22 by the contact 23 in the transmitter is installed on the zero contact O, then with synchronous rotation of the disks b

Transmitter and receiver at the moment of contact of both contacts 7 with the corresponding zero contacts 0.0j

. A current will flow through the circuit, and a spark will flow in the receiver (at the contact Oi),

corresponding to the zero position of the transfer. When contact 23 connects both parts of one of the fixed contacts 12 in the transmitter, moving contact 7, each time it touches this contact, it will replace the device’s electrical circuit twice. And, therefore, a second spark will appear in the receiver. in the spark gap of the corresponding contact 12, which was hitting at this moment against the sliding-contact 7. At some speed of movement of the sliding contacts, the frequency of occurrence of sparks will be sufficient

accurate for an impression of continuity. Obviously, with the same speed of movement of the sliding contacts of the devices 9i and 9, the position of the spark will remain unchanged. If another fixed contact is connected in the transmitter, then in the receiver there is a spark that is offset from the first by the time t spent by the sliding contact of the transmitter to travel the path between the two fixed closed contacts. Since the sliding contacts are 7

the condition is moving at a uniformly similar speed, the angular counting of the n of both devices will be the same, i.e. the spark will be set in the contact gap having the same sequence number with the second transmitter contact turned on. Moving the lever 22, we obtain the corresponding. the movement of the spark in the dials of the receivers or, in other words, the spark. will move synchronously with the lever 23 of the transmitter.

In case of incomplete synchronization of watch mechanisms, in which the zero position O begins to shift, the disk 11 in the receiver is not rigidly fixed and can be turned to eliminate the inaccuracy.

Instead of spark gaps in the receiver, electric lamps or electromagnets can be placed, by means of which the presence of current between the corresponding contacts is ascertained. The electromagnet at the zero point Oj in this case can be used to service the adjusting rotating contact 7 of the device. In addition to the device, in addition, wireless transmission of energy from the transmitter to the receiver can be applied. The author notes that the essential advantage of the proposed device is its simplicity, speed of transmission over fairly large distances (20 kilometers or more) and the small number of wires required (two), as a result of which a conventional field telephone cable can be used.
