A disadvantage of the known device is the complexity of the circuits, which means that for a bit reading of information from a two-bit matrix memory block, the number of outputs of the circulating device and, consequently, the number of output elements must be equal to twice the number of columns of the memory block.

the second input of the element "OR, with the input of the ring counting circuit, with the prohibiting input of the element" Prohibition and with the prohibitory inputs of the pneumorele with a spring, and the output of the element "P1LI connected to the control

the high-end switch of the memory block; the output of the element Zairet is connected to the control inputs of the keys for erasing the most significant bit of the memory block, the outputs of the amplifiers of the lower bit of the block

the memory is connected to the chambers of the springs of a pneumorel with a spring; the outputs of the higher bit amplifiers of the memory unit are connected to the control inputs of the pneumorele with a spring, the outputs of which are connected to the inputs of the pneumatic belt puncher.

The inverted output Pt of the generator is connected to the input of the switching unit 7, to the input of the element Ban 19 and to the control inputs of the erase valves 15 of the lower order of the memory block.

The output of the trigger 4 is connected to the second input element "OR 12, with the input of the ring counting circuit 5, prohibiting the input element" Ban 19 and with the inhibiting inputs of the pneumatic relay with spring 20. The outputs of the switching unit 7 and the ring counting circuit 5 are connected to the inputs of the decoder 6. Outputs the decoder, which are the outputs of the enclosing block, are connected to the first control inputs of the junior and senior bits 1 and 2 of the memory block. The outputs of the lower and oldest bits of the memory unit are connected to the outputs of the corresponding switch 13 and 14.

The outputs of pulse counter 8 are connected to the converter inputs code-analog 9 and to the converter inputs code code 10, and the converter outputs code analog 9 are connected to the first inputs of the comparison elements 11. The outputs of code converter code 10 are connected to the inputs of switches 13 and 14, and the outputs of the elements of comparison 11 are connected to the second, control inputs of the low and high bits 1 and 2 of the memory block. The second inputs of the elements of comparison 11 are connected to the outputs of the sensors of the controlled technological parameters. The control inputs of the higher-order switch 14 are connected to the output of the OR 12 element, and the lower nozzles of the switches 13 and 14 are connected to the corresponding amplifiers 17 and 18 and the wipe-out valves 15 and 16.

The outputs of the Inhibit 19 element are connected to the control inputs of the erase valve 16 of the highest bit of the memory block. The outputs of the amplifiers 17 are connected to the spring chamber of the pneumorele 20 with a spring, and the outputs of the amplifiers 18 are connected to the control inputs of the pneumorel 20. The outputs of the pneumorele are connected to

the entrances of the pneumatic belt punch 21.

The operation of the device is as follows.

At the beginning of the cycle, from the control unit, not shown in the drawing, after the start, PU pulses arrive at the input of the pulse counter 8, which generates signals of the decimal code. From the output of the pulse counter, the code signals are fed to the inputs of the code-analog converter 9 to form a stepped ascending sweep signal corresponding to the code value, and to the inputs of the code converter code 10

to convert the decimal code to binary, binary-decimal, international telegraph code or any other code used in electronic computers. With the coincidence of the values of the controlled technological parameters that arrive at the second inputs of the comparison elements

11, from the sensors, with the scanning signals, at the outputs of the comparison elements, the signals arriving at the second control signals appear.

the inputs of the junior and senior bits 1 and 2 of the memory block.

At the same time, the corresponding columns of the memory block from (broken and recorded

the code coming from the outputs of the converter code 10 through the upper nozzles of the switches 13 and 14 to the inputs of the memory block. After the end of the recording cycle from the control unit, the PCht signal turns on the generator 3, which generates the PI clock signals for the ring counting circuit 5. The PI clock signals go to the input of the trigger 4, which divides the clock frequency signal of the ring counting circuit 5. The ring counting circuit

and the decoder 6 generates the output signals of the encircling unit, which in turn unlock one of the columns of the younger and most significant memory blocks. At the same time, the output signal PI unlocks the switch 13

younger bit and through the element "OR

12 - switch 14 high-order. The output signal of the trigger 4 locks the element “Prohibition 19 and the pneumatic relay with spring 20, as well as through the element“ OR 12 duplicates the rubbing of the switch 14 of the senior level. At the same time, the values of the recorded low-order code of 1 memory unit through the switch 13 are fed to amplifiers 17, the output signals of which through

20 are fed to a pneumatic belt punch 21, which prefers the read code.

The values of the recorded high-order code 2 memory blocks through the switch 14 are sent to the input of amplifiers 18, the output signals of which are sent to the control inputs of the relay 20, which are locked by the output signals of the trigger 4. After the termination of the Pt signal

a generator appears inverse output

The signal Pi, which, by means of the switching unit 7, performs the "zeroing of the outputs of the decoder 6, i.e. the encircling device, allows the use of a pause for performing additional operations, for example, for drawing punched tape. In addition, the inverse output signal unlocks the erase valves 15 to empty the output lines of the lower bit 1 of the memory unit, as well as the input element of the Inhibit 19, which remains locked due to the presence of a signal at the locking input from the output of the trigger 4.

When the next Pt signal appears, the counting trigger 4 is brought to the state "O, which is not" (Leads to a change in the state of the ring counting circuit 5, i.e., the output signal appears on the same output of the encircling device as in the previous cycle generator 3.

In the absence of an output signal of the trigger 4, the output signals of the pneumorele 20 are fed to a belt-mounted pneumatic hammer drill 21, which punches the code read from the high bit 2,: memory block. When the inverse output signal P appears, a "Zero-out" obstructing device is turned on and the element "Ban 19" is turned on, the output signal of which unlocks the 16 dL erase valves, the high-resolution output lines of the 2 memory blocks. When the next two signals appear on the generator, the cycle repeats for the next column of the memory block. Thus, in this device, for a bit reading of information from a two-bit matrix memory block, the number of output elements of the encircling device is halved, and taking into account the introduction of additional elements in the trigger and with the counting input, by 30%.
