The invention relates to the technique of electrolysis and can be used in telegraphy and the transmission of telegraph messages.

The purpose of the invention is to increase the amount of information transmitted during the transmission of alphabetic text.

The drawing shows a structural electrical circuit of the proposed transponder.

A telegraphic transmitter transmitter contains a transmission distributor 1 consisting of a generator 2 records, a transmitter control unit 3, a generator 4, a divider 5 and a division unit 6, a switch 7, a keyboard unit 8, a unit 9 for automatic recording in the register drive combinations consisting of elementations OR 10-13. trigger 14, elements AND 15-17, differentiating chains 18-20, lep 21 and second 22 elements OR, element 23, accumulator 24, consisting of register 25 and decoder 26, output matching unit 27.

The telegraph transmitter operates as follows.

Depending on the type of information transmitted, the transmitter is set to one of two modes using switch 7. When transmitting semantic text and numbers from the output of switch 7 to the second input of the element I 23, a “zero signal arrives (mode I).

With the register RUS turned on (not shown) - the presence of a control signal at the output of the keyboard unit 8 and pressing one of the keys on which the characters of the Latin and Russian alphabets are combined - from the service output of the keyboard block 8, signals are sent through the OR element 10 of the block 9 and the second element OR 22 to the first input of the trigger 14, and from the control of the output to the taviature unit 8, directly to the recording driver 2 and the transmitter control unit 3 of the transmitting distributor 1.

The trigger 14 is triggered through element 15, to the second input of which a signal is output from the keyboard unit 8, and the differentiating chain 19 automatically records the register combination RUS in the first stage of the accumulator 24 to the command of block 3. the records of the transmitting distributor 1 are transferred one after another; 1to the second, third, ..., nth stage of the register 25 of the accumulator 24. After releasing the first stage, a code combination is written into it, which appeared on the information in keyboard unit 8 moves when pressed klavipsch.

After registering in the nth step of register 25 of accumulator 24 of the first combination, at the command of block 3, block 6 is disconnected

It provides transmission to the line through the output matching unit 27 sequentially starting, informatization and stop parcels encoded with the m-element code MTK-2. The state of block 6 is cleared by block 3, which stops the operation of block 6 after 0.5 to the beginning of the stop only if the combination is not recorded in the 5th stage of register 25 (the stop condition continues until the next keystroke).

When register 25 is full, accumulator 24, i.e., filling all of its steps with combinations, a signal from input of decider 26 sends a signal to the input of the blocking unit (not shown) of keyboard unit 8 (mechanical or electrical). The keyboard unit 8 is blocked and (or) a signal is received that the accumulator 24 is full. After releasing the first or first and second steps of register 25 (when overwriting the combimations in subsequent stages), the control signal from the output of the decoder 26 is released and the keyboard unit 8 is unlocked.

With further pressing of the key of this group, writing and reading code combinations occurs in a similar way.

When you press one of the keys, on which numbers or letters of the Russian alphabet are located (W, Shield), the digital register signals are sent to the transmitting distributor 1, and from the service output of the keyboard unit 8, respectively, through the elements OR 11 and 12 and through the element OR 13, the element AND 16, the second input of which is affected by the signal from the output of the keyboard unit 8, and the element OR 12 - to the second input of the trigger 14. The latter is triggered and through the differentiating chain 18 is automatically recorded in the first stage of the accumulator 24 The high-frequency clock cycles of the transmitting transceiver. Item 1 are rewritten sequentially in the 2, 3, ..., nth steps of the shift register 25 and through the output matching unit 27 to the communication line. After the release of the first stage, the code combination that appeared on the information outputs of the keyboard unit 8 when the key is pressed and which is transmitted to the communication line in the same way is written into it.

Thus, when transmitting text using the key, on which the letters of the Latin and Russian alphabets, numbers, letters of the Russian alphabet (W, W, etc.) are located, the register keys RUS and CIF are not pressed on the digital register, because during the transition From the key to the key, the corresponding register combination is automatically written to the drive 24.

However, if in the text after the number or letter of the Russian alphabet 8, 9, etc., one of the letter of combinations 1-4, 11-14, 19, 22, 24, 26 is in the Russian register or after the letter of the Russian alphabet (combined on the key with the letter of the Latin alphabet) is one of the icons of combinations 1–4, 11–14, 19, 22, 24, 26 transferred to the digital register; in order to correctly transfer text, the register key is respectively pressed on the keyboard unit 8 to ENG or DIF. The register combination for the information outputs of the keyboard unit 8 is supplied for recording in the first stage of the accumulator 24 and, under the influence of the transmitting distributor 1, is rewritten sequentially into 2, 3, ..., the nth stage of the register 25, the output matching unit 27 and then through the line connection.

When one of the key combinations 1-4, 11-14, 19, 22, 24, 26 is pressed, the signals are sent to the transmitting valve K a from the additional service output of the keyboard unit 8 through the first element OR 21 — to the first input of the element 23, to the second the input of which is fed “zero signal from switch 7. Element And 23 does not work, which eliminates the recording in the first stage of accumulator 24 of a false register combination. This code combination is recorded in the drive 24, which is located at the information outputs of the keyboard unit 8, and the operation of the transmitter is repeated.

The operation of the transmitter when typing alphanumeric text is based on the fact that in the alphabetic text there are no icons of the combinations 1–4, 11–14, 19, 22, 24, 26 on the digital register (not shown). Therefore, when transmitting alphabetic text from the output of the feed line 7 to the second input of the element And 23, a “single signal (mode 2) arrives.

The operation of the transmitter when typing alphabetic text using keys that combine letters of the Latin and Russian alphabets, letters of the Russian alphabet 8, U, etc. on the digital register does not differ from its operation when transmitting the semantic text. However, if in the letter text after any letter of the Russian alphabet 8, U, etc., is any letter. A, B, C, D, K, L, M, H, C, F, 6.3 (respectively, combinations 1–4, 11–14, 19, 22, 24, 26 in the Russian register), the key is pressed without

Pre-press the register key RUS. As a result, signals appear at the output of the keyboard unit 8, one of which acts on the transmitting distributor 1 and the other through the first element OR 21 is fed to the first input of the element AND 23, to the second input of which a "single signal from the output of the switch 7 Element And 23 is triggered, and at its output a pulse appears, which through

the second element OR 22 is fed to the input of the trigger 14 of the block 9. The trigger 14 is triggered and through the element 15, the second input of which is given a signal from the output a to,: 1 of the control unit 8 and the differentiating chain 19, automatically writes the register combination RUS in the first stage of the accumulator 24.

Further, under the influence of the transmitting distributor 1, this combination is rewritten sequentially. 2, 3, ..., the n-th stage of the register 25 and through the output matching unit 27 to the communication line. After the release of the first stage of the packopit. 24 there is a recorded code in it that combines the information on the keyboard keyboard information outputs. 8).

If in the process of transmitting a literal text you need a persGggi from these keys to any of the clavines with the letters of the Russian alphabet Sh. Shch, etc., you need to press the key also without first pressing the register clavial of the DSC. In this case, the transmitter works in the same way as in the transmission of semantic text.

For the transmitter to operate in the Latin register, the control signal from the output of the keyboard unit 8 is removed and fed to the output b and then to the input of the element 17. At the same time, the operation of the transmitter does not change. However, when one of the keys with signs of the Latin and Russian alphabets is pressed, triggering of trigger 14 leads to automatic recording of accumulator 24 into the first stage (via element 17 and differentiating chain 20) of the register combination L.LT.
