SU126909A1 - Device for imprinting marks on electrochemical paper when wiring - Google Patents

Description

A device is provided for imprinting marks when wiring on electrochemical paper in the form of a mosaic of individual points.

Marks are printed by means of a matrix consisting of stationary rod electrodes pressed against a stationary electrochemical paper at the moment of stamping, the characters being printed by passing a current through a group of recording rod electrodes corresponding to a certain sign decrypted from the received code 1 signals using decrypting electronic devices.

When using the described device in a tape or roll type telegraph unit, the only mechanical operation is to pull the ribbon or roll out the paper roll. Signs are recorded on electrochemical paper in the form of a certain size of dots when current is passed through a set of stationary electrode rods that press the electrochemical paper to a flat conductive contact, which is not drawn at the time of printing the signs.

The distribution of the rod electrodes in the matrix, numbered from 1 to 34, is shown in FIG. 1. The number of rod electrodes can be increased several times, which will improve the quality of character outlines and eliminate the transition of one sign to another when the individual rod electrodes loosely adhere to the paper surface. The configuration of dotted letter characters is shown in FIG. 2

hysteresis loop. Depending on the received code combination, a certain set of two pairs of input terminals & i, 62, bz, 4. bb (Fig. 3) are given the same fixed potentials v. Each of five pairs of input terminals corresponds to a code parcel defined by the number.

At the 32 outputs of the circuit (Fig. 3), different potentials are obtained, and only at one of the output terminals the maximum potential is obtained with the currentless sending and, in one case, the minimum potential at potential v.

In the matrix circuit (Fig. 3), the output voltages are added using the resistances R and with the distribution and polarity of the input potentials shown, the maximum potential will be at the first output and the minimum at the 32nd output.

Indicated in FIG. 3 the polarity of the input voltages can be obtained from lamp trigger circuits, from trigger circuits on baseless thyratrons or on crystal triodes such as n - - p, etc. When used in triggers, the crystal triodes of type and output voltages will be inverse.

The maximum or minimum potentials obtained in matrix circuits at the outputs are used to control key circuits of the printing device.

The simplest version of the printing device will be when the potential of each of the output points of the decimator matrix scheme is supplied to a specific key scheme. When the potential at this point becomes maximum or minimum, the key circuit passes current to the corresponding group of printing rods corresponding to this sign. Since each of the decomposition elements participates in the printing of several characters, it is necessary that all other elements of different elements are not printed. characters for which this element is generic must be electrically separated.

The simplest method of such separation using semiconductor diodes is shown in FIG. 4. Managed key schemes are conventionally shown in the form of KNK keys. Each of the keys must connect a specific group of printing rods to the voltage source. FIG. 4 shows only three rods c pressed against electrochemical paper b. The middle rod is common to both signs. With this method of separation, the number of diodes in, connected to each of the printing rods, is equal to the number of characters in the printing of which this element participates.

The diagram of the interpreting and printing devices, in the case where the key scheme controls several electrode rods, is shown in FIG. 5, which shows a controllable key diagram K, separation diodes 0 and printing electrodes rods involved in imprinting the letter sign D on electrochemical paper b. The code telegraph parcels coming from the distributor act on the release schemes C, from where the potentials of the corresponding polarity are added to the input of the matrix scheme of the decoder D, depending on the received code combo. The maximum or minimum potential supplied by the decoyr controls the key scheme of the mark to be printed.

FIG. 6 shows another way of separating the rod electrodes. When each rod a has a CBOio controlled key circuit K.

The division of common for a number of characters of the printing rods is carried out with the help of cores G with a rectangular hysteresis loop (Fig. 7). Each of the output windings (not shown in the drawing) of the cores G is connected to one of the printing centers (not shown in the drawing).

The imprinting of the corresponding signs is made when a pulse of a certain polarity appears in the output winding connected to the rods. Thus, in order to imprint the mark L into the common winding of certain cores G, a current pulse is applied, reversing only these cores from the initial position that is the same for all cores. In this case, pulses of the desired polarity appear in the output windings. The impulse arriving in the horizontal windings returns the overmagnetized cores to the initial position after imprinting the mark.

The transfer of registers in the apparatus is carried out electrically with the same group of printing rods-rods. It describes a method for translating registers in an apparatus, in which the decoding of code combinations and the separation of printing rods is achieved by using magnetic cores with a rectangular hysteresis loop.

The code windings bi-65 and windings ye (Fig. 8), to which the switching pulses are fed, are connected to the simple Russian registrar's registers P, the Latin L and digital C. The decoder registers of the registers are made on the magnetic cores G used to separate them.

When receiving a telegraph code combination. The output pulses of the decoders of all three registers R, L Z reversal certain cores of their sections. The cores -D of separation of each of the three registers have a separate common winding, into which a constant magnetizing voltage is applied that prevents them from magnetizing with a decoder pulse. The output pulses of the decoder remagnetize only the separation cores of the printing device.

The switch circuit has three stable equilibrium positions. When Receiving the register transfer code combinations, the output pulses fed from the decoder P through the clips 3, 3, 3 are switched in the I circuit to one of three equilibrium positions. In this position, iodine magnetisation is not applied only to the cores раздел of the division of the register that is currently operating.

Most of the rod electrodes are involved in imprinting the characters of all three registers; therefore, three windings are connected to the rod. In order for the two windings not to shunt the printing rod at the appearance of a pulse, diodes c are included in the third winding.

Other schemes can be used to separate the registers.

On a roll unit for electrically selecting the position of the imprinted mark along the line, stationary arrays of printing electrodes are installed (Fig. 9) according to the number of characters per line. The selection of the o-defined matrix is carried out with the help of controlled key schemes K, and for control of key schemes the-rings of the counter C of the number of printed characters are used. If it is sufficient to apply one cycle of reversal of the separation cores G of the printing device for imprinting marks, then the counter can also be assembled on magnetic cores - 3 - l 126909

nikah on one-way or two-way schemes. The next switching of the magnetic counters is carried out simultaneously with the remagnetization of the separation cores. At the same time, the key scheme will be unlocked simultaneously with the appearance of their impulses on the selected cores.

If it is necessary to apply several cycles of reversal of the separation cores for imprinting signs, then as the counter cascades it is required to use active static release schemes, giving certain fixed potentials between the switchings, with the help of which it is possible to control the key circuits.

For controlling key circuits / C (Fig. 10), dynamic trigger circuits can be used for several switching cycles on mother cores D. In one of the equilibrium positions in such circuits, output pulses appear continuously, in tandem with switching, 13 the other position, the output pulses are missing. Dynamic trigger circuits are included between the counter cascades on magnetic cores C and controlled key circuits K. The activation of certain dynamic trigger circuits D will occur when a pulse appears in a certain stage of counter C. And the switching-off pulses at input L ,. The pulses for unlocking the key circuits are supplied at the required points in time if the dynamic trigger circuits are switched by the pulses applied to the Lz input, simultaneously with the non-magnetic core / separation of the printing rod electrodes.
