Description

The device according to the invention is intended to convey indications, for example, extremely liquid liquids in tanks and so on. from several objects to one, located far from them, the receiving point and allows to transmit these readings, even if they are carried out simultaneously, through one line.

The drawing shows a diagram of the device.

At the transmitting point, relays 2 and 7 are set according to the number of objects that need to be transmitted, pulse relay 13 and current distributor 12, and at reception point relay 75, current distributor / 7 and, according to the number of transmission objects, relays J9 and 2 /. Current distributors-type seekers. To each contact of contact rings TO, 11 vi 18, along which the current distributor brushes slide, relays 7 corresponding to a particular object and pin 5 of relay 2 on the transmitting side and relay 19 on the receiving side are connected. The drawing shows, for example, the attachment of the indicated parts, related to one object, to the upper contact of the contact rings of the current distributors.

When changing, for example,

(76)

LIQUID in the tank or the like is briefly automatically pressed by means of a device / contact and closes the circuit of relay 2: ground, contact 7, turning 2, contact P. battery 8, ground, relay 2 operates and closes contacts 3, 4, 5 n 6, which do not open when contact 7 is released, since relay 2 is blocked by j contact and continues to operate. Contact 6 of relay 2 closes the circuit of the pulse relay 75 and current distributor 72, as a result of which the brushes of the latter begin to move along the contacts of the rings JO and 77. At the same time, using the contact M, current pulses with the pulse frequency of the relay are transmitted through the line wire (in the upper drawing) 75. The relay 75, respectively transmitted pulses, comes into action and the contact 76 closes the circuit of the current distributor 77, the brushes of which due to this will move synchronously with the brushes of the current distributor 72.

When brush current distributor 72 ;. moving along the ring 77 will reach the contact connected with contact 5 of relay 2, and the brush of the current distributor 77 simultaneously reach the contact connected

with winding / 9, the circuit will close the coils of the relay 19 at the receiving point: ground, linear battery B, pin 5, jack, solid ring //, extra wire (bottom drawing), solid. RING J8, brush, winding relay 19 , zedal. Relay 19 will come into effect and, in its turn, by contact 20 will close the circuit of relay 21. After a very short time after closing the last two circuits, another of the current distributor 12, connecting a solid ring 10: contact, connected to the winding of the relay 7, will turn it on last in the current source circuit: positive pole, contact; d 4, relay 7, brush, solid ring 10, negative pole. :. Relay 7, having brought its measles 9, will turn off the relay 2 pins 3, 4, 5 and 6, which will open and return to their original position. Then the pulse relay 13 and all other rale 7, 12, 15, 17, 19 will also turn off 1, the current distributors will stop working, and contact 20 will open, causing one current pulse in relay 21. After the next contact closure .7, the relay 21 will again receive a current pulse, etc. Thus, the relay 21 at the receiving point, actuating the corresponding device, repeats in one form or another the actions performed by the transmitting mechanism. Such phenomena as changes in the water level in reservoirs and locks, the volume of gas in gas holders, etc., cause two successive closures of the contact / after a period of time exceeding the time of one revolution of the finders' brushes. Therefore, it is quite obvious; it is clear that if within the specified time interval a closure occurs.

to various objects, the pulses to the corresponding relays 21 at the receiving point will be transmitted through the line (in the drawing, the lower wire) in the order along which the moving brushes of the current distributors attach to the corresponding contacts of the rings. With such a consistent transmission of pulses from different objects, the common pulse relay 13 and current distributors will operate until the last of the contacts 6 is opened in the specified queue.

The subject matter of the invention.
