The Morse code transmitter contains a block 1 of a punched tape, a read block 2, a first decoder 3, a distributor 4, a pause generator 5, the first element OR 6, a starting block 7, a delay block 8,

shaper 9 sign duration, valve 10, shaper 11 dash, generator

12-stroke pulses, the second element OR 13, the shaper 14 code signs, the third element OR 15, the output unit

16 mates, switching unit 17, second decoder 18 and additional elements OR 19.

The Morse code transmitter works as follows. The transmitter provides two modes of operation: transmission mode

full morse code and digital text transfer mode abbreviated morse code. The start of the transmitter operation is the same for both modes and proceeds as follows.

Sets the required wiring speed (duration t). Switching unit 17 is installed in one of two positions defining the mode of operation. On the ice, holes that correspond to the required Morse code signs are packed. The valve 10 is open, and the clock pulses of the generator 12 are passed to the inputs of the distributor 4, the driver 5, the driver 11 dash and block 8 delay. Since the information inputs of these blocks do not receive signals, there are no pulses at their outputs. The output conjugation unit 16 outputs a negative potential to the manipulation line.

To initiate the transfer, it is necessary to apply a pulse from the output of block 7 to the input of the element OR 13. The signal from the output of block 7 is fed through the element OR

13 to the information input of the imaging unit 5 and the reset of the distributor 4. The next clock pulse advances the recorded signal from the first cell of the imaging unit 5 to the input of the second cell and to the input of unit 1. The punched tape is pulled one step. The next clock pulse advances the signal recorded in the second cell.

shaper 5, which is fed to the information input of the first cell of the distributor 4 and to the inputs of the readout unit 2, the first descrambler 3 and the second decoder 18.

After the first step of block 1, made under the influence of a pulse from block 7, the further operation of the transmitter is determined by the presence or absence of perforations on the tape.

If there are no holes in the punched tape, there are no signals at all outputs of the readout unit 2, which determines the appearance of the signal at only one output of the decoder 3 and corresponds to a space. The specified signal is fed to the input of the block 8 delay. With the arrival of the next clock

the pulse to the clock input of the delay unit 8, the signal from its output through the element OR 6 is fed to the inputs "reset of the distributor 4 and to the information input of the cell 5-1 of the driver 5. With the arrival of the next

The clock pulse signal recorded in the cell 5-1 is advanced along the driver 5 and is fed to the input of block 1. The punched tape is advanced one step. The process of drawing the tape without forming a code pattern in the output conjugation block 16 continues until the tape has no holes for the perforations. As soon as the tape in the vehicle has openings, the operation of the transmitter depends on the transmission mode set, i.e. the position of the switching unit 17.

Suppose, for example, that a transmitter is required to operate in the full Morse code mode, there are holes on the tape, corresponding to the numbers "1," 7, ... (Fig. 2). The number “1” corresponds to the holes in the tracks Ar, AJ, L, Lu (dashes on the second, third, fourth and fourth places in the Morse combination) and Br, Bi (five elements in combination). The switching unit 17 is set to a position in which the decoder 18 is disconnected from the outputs of the readout unit 2, and the inputs of the imaging unit 14 are connected to the readout unit 2.

With the arrival of a pulse from the output of the cell 5-2 of the imaging unit 5 to the inputs of the readout unit 2 and the decoder 3, and to the information input of the first cell of the distributor 4 to the output of the readout unit 2, corresponding to their tracks Ar, As, A, Aj and Bi, Bj along are signals. The signals corresponding to the tracks of the AG. AS are fed to the inputs of the cells 14-2-14-5 of the imager 14, and the tracks of Vg., Vz to the inputs of the decoder 3, the outputs of which, and the investigator, and the inputs of the block 8 delay , elements OR 19 and cells of the imaging unit 9 signals are absent. With the arrival of the next clock pulse, the signal recorded in the first cell 4-1 of the distributor 4 advances along the distributor 4 and enters the cell 4-2 of the distributor 4 and to the input of the OR 15 element as well as to the input of the cell 14-1 of the driver 14. the input of the cell 14-1 of the imaging unit 14 was not received from the reading unit 2 (there is no hole on the track Ai), the signal of forming a dash from the output of the cell 14-1 to the element OR 13 is not received. The next clock pulse causes the signal at the output of the cell 4-2 of the distributor 4. Since there are no signals from the decoder 3 to the inputs of the cells of the imaging unit 9, the signal from the output of the cell 9-1 to the element OR 6 is not received. The next clock pulse causes a signal at the output of the cell 4-3 of the distributor 4, which is fed to the input of the element OR 15 and to the input of the cell 14-2 of the driver 14. Since the other input of this cell has already received a signal from the output of block 2 (track AI) at the output of the cell 14-2, a signal appears, which through the element OR 13 enters the input "prohibition of the valve 10 and the information input of the driver 11 dashes. The fan 10 is closed and the next two clock pulses do not pass to the clock inputs of the distributor 4. The signal from the output of the cell 14-3 goes to the input of the OR 15 element and through it to the output conjugation unit 16 until the next clock pulse arrives at the valve 4, i.e. for 3f. Two successive clock pulses arrive only at the clock inputs of the driver of the 11th dash and to the inputs of the driver of the 5th, causing the information signal to advance through the cells of the driver of the 11th dash. With the arrival of the next clock pulse, the dash 11 driver generates a signal to the input “the resolution of the valve 10, and the clock pulses again begin to flow to the distributor 4. The formation of the Morse dash sign is completed. The formation of the third, fourth and fifth elements (dashes) in the numeral “1 is similar. With the arrival at the clock inputs of the distributor 4 a pulse corresponding to the end of the last fifth element, a signal appears at the output of the last cell 4-10 of the distributor 4, which is fed to the input of the element OR 6 and then to the inputs "reset of the distributor 4, driving it to the original state, and at the input of the first cell of the imager 5.

The next clock pulse advances the signal recorded in cell 5-1 to the input of cell 5-2 of the former 5 and to the input of unit 1. The punched tape is advanced one step, and the signals corresponding to the preceding "1" are removed from the output of reader 2. With the arrival of a pulse from the output of the cell 5-2 of the former 5, the latter is recorded in the first cell of the distributor 4 and is fed to the inputs of the reader 2 and decoders 3 and 18. The transmitter is ready to form the next sign recorded on the tape.

The formation of alphabetic characters containing a smaller number of elements in the sign (from one to 4) in the transmitter is similar, except that the signal of the end of the character arrives at the element OR 6 not from the output of the last cell of the distributor 4, but from the output of one of Shaper cells 9.

Claims (1)

A sequence of unipolar dashes and dashes, separated by a pause of duration t and representing the sign of a Morse code, is formed by summing the signals from the outputs of the odd-numbered distributor cells 4 by the OR element 15. In the output conjugator 16, the electrical parameters of the signal are converted into the values required for transmitting Morse code signals along the manipulation line. The formation of digital characters on the reduced Morse code with the same tape is as follows. Let, for example, it is required to transmit the same numbers “1,“ 7, “3,“ O, ..., but with an abbreviated code. For this, the switching unit 17 is set to a position in which the de-embedder 18 is connected to the outputs of the readout unit 2 corresponding to the tracks AI -f Ag punched tape. The transmitter, as well as in the full code transmission mode, is started by applying a pulse from the output of the starting block 7. The difference in the transmitter operation when working with the reduced code is that the driver 9 and driver 14 are controlled by the decoder 18, since Outputs of the decipheror 3 are missing. When reading from the punched tape the numbers "1," 2, "3," 5, which in the abbreviated code do not contain a dash, the output of the decipher 18, connected to the cell 14-1 of the driver 14, is absent. When reading from the punched tape the digits "6," 7, "8," 9, "O, which in the abbreviated code begin with a dash, a signal appears at the output of the decoder 18. The presence of signals on the other four outputs of the decipheror 18, connected via the elements OR 19 to the driver 9, is determined by the number of elements in the Morse sign (Fig. 3). The processes of formation of the elements of a Morse code mark in the mode of transmission by an abbreviated digital code are similar to the processes of forming the characters of the full Morse code. The use of the proposed transmitter can reduce information transmission times and punched tape consumption.
