The invention relates to the processing of materials by pulsed action, to a technique for measuring, recording, processing information, and the like. and can be used in the mining industry.

The purpose of the invention is to enhance functional and operational capabilities and reduce the likelihood of false alarms.

This goal is achieved in that the device is made with two inputs, which are the ends of the input transmission line, and both transmission lines are located and are configured to transmit information from input to output in the meeting zone (summing) of both input pulses applied to the ends input line. The location of this zone along the length of the input line is predetermined by the difference in the arrival times of the input pulses and the gradient of their propagation velocity.

The transmission lines in this device can be performed, for example:

of a hundred conductive material, the information carrier of which is a surfactant, having a speed of 1.62 to 4.0 km / s (depending on the type of material);

from a material supporting a self-propagating high-temperature synthesis reaction, for example, a TiNi alloy having a flameless combustion temperature of the order of 1237 ° C and a combustion initiation temperature of the order of 270 ... 320 ° C. Here, the information carrier is the combustion front propagating with stable speed of about 2 cm / s;

from explosive material, the information carrier in which is the detonation front (region of high pressure and temperature), depending on the formulation, shell strength and other parameters, having a stable speed (propagation along explosives) from Ts. 2 km / s to 8, 5 km / s

In the variant with a Shunt-guiding line, in order to reduce the likelihood of non-transmission of information to the output line (due to the very probable antiphase of the surfactant in the meeting zone), the input transmission line is equipped with input converters made in the form of filters with different (preferably substantially for example, by order of frequency of transmission.

In this case, at the wavelength of the low-frequency surfactant, several wavelengths of a higher-frequency one will be laid, and therefore always in the meeting zone at the half-length of the low-frequency surfactant there will be a section where the waves encountered will be combined, and their total amplitude will be sufficient for contact t of the wave-comb interaction with the output acoustic wire lines.

In the version with a transmission line from the explosion

In order to exclude the influence of the detonation front going from one end to the other on the source of the input informational pulse that has not yet worked, located near the opposite end of the input line, there are decoupling nodes installed on the device’s input - information transmission unidirectional nodes made , for example, in the form

5 installed at the end of the transmission line with a gap of a missile element (plate, rod), accelerated by a throwing charge of the explosive and its impact on the end of the input transmission line, exciting the detonation process in it.

In order to maintain the operability of the device in the event of an input transmission line being consumed as a result of its operation by a delayed command received only at one of the inputs, this device is equipped with at least one additional duplicate input transmission line that is explosion-isolated from adjacent input lines. To give the ability to automatically introduce an adjustable delay equivalent to the (corresponding to) the time difference between the arrival of the input pulses, the output transmission line is located along the input and is made in comparison with it with

5 with a different (lower or higher) average speed of information dissemination. At the same speeds of information distribution, the delay will not depend on the magnitude of the time difference

0 arrival of input pulses, because the length of the geometric path of the delayed input pulse, folding from the section to the meeting point (its length depends on this parameter) and the section after it,

5 is always the same.

In another embodiment of the implementation of an adjustable delay (independent or compatible with the one just shown), the input and output transmission lines are also located along each other, but at least one of them is made with a delay gradient varying along its length (otherwise, with current information dissemination rate).

5 in particular, when applying a delayed pulse to the input farthest from the output of the device to realize a delay proportional to the difference in the input pulses, the output transmission line is executed with decreasing in

the direction of its output by the delay gradient (the input line may also have a non-zero gradient, but of the opposite sign).

An output pulse can also be taken from the opposite end of the output line, but with the inverse law of changing the delay value (the greater the time difference between the arrival of the input pulses, the smaller the delay).

In order to give the device the ability to perform the functions of a match pattern (or a controlled key), the output transmission line is located with the possibility of interaction not with the entire input line, but only with a portion limited in length that is at the same or different time distances from its ends x

The sameness implies the generation of an output pulse only with the simultaneous appearance of input pulses at both inputs.

In all other cases, this device is a decoding or filtering element transmitting input pulses that follow with a strictly defined mutual delay.

This feature is very useful in terms of improving noise immunity, in particular, explosive circuits used in the mining industry, in the processing of materials by explosive energy, which improves the safety of these operations.

The invention is illustrated by illustrations.

Figure 1 schematically shows a device in which the transmission lines are made on the basis of BB; Figures 2 and 3 show two variants of the mutual arrangement (orientation) of the input and output transmission lines in a device that can be used as a coincidence circuit, or a decoder, a filter for a pair of input pulses following with a strictly specified mutual delay; Fig. 4 shows a device made on the basis of transmission lines made of acoustic conductive material.

Along the input transmission line 1 with a clearance of 2, there is an output transmission line 3, the output of which 4 is loaded with an executive unit 5. At the ends (inputs) 6 and 7 of the input line, a unidirectional (one-way) information transmission unit is installed on the decoupling unit 8, 9 (only inside the line ), consisting of 10 plates 11 thrown by charges, striking at the ends of the input transmission line and causing the propagation of information pulses 12 and 13 in it in the form of detonation wave fronts (if the line and BB), or surfactant (if the line is acoustic) .

In the meeting zone, these pulses are added up, and the amplitudes of the total pulse (burst) 14 become sufficient to penetrate the gap (gasket) 2 and excite the information pulse in the output transmission line 3.

Input decoupling units 8, 9 (analogs of diodes in electrical circuits) eliminate the harmful effects of pulse 13 on source 15 of input pulse 12, and pulse 5 12 on source 16 of second input pulse 13.

On the opposite side line 1 near the output line 3 there is a duplicate input circuit (from the transmission line

0 17 with decoupling nodes 18 and 19).

The distance 20 of the total burst 14 (the interaction zone of pulses 12 and 13) from the input 7 is predetermined by the difference in the arrival times of the input pulses 12 and 13, as well as by the gradient of their propagation velocity in line 1.

If both lines are parallel to each other over their entire length, the allowable value (so that pulses meet) at the same time is maximum.

If you want to make it minimal, for example, when using this device as a coincidence circuit (generating an output pulse only when

5 coincidence in time of pulses 12 and 13), then the area 21 of the interaction of both transmission lines is artificially reduced. According to figure 2 this is achieved by the cross-location of transmission lines 1 and 3, and

0, as shown in FIG. 3, by diverting the end sections 22 and 23 of the output transmission line 3 from the input to a distance at which the amplitude of burst 14 is not sufficient for (excitation of an information pulse 5 in them. This can also be achieved by introducing between both lines mi in certain areas of their length (outside zone 21) of insulating gaskets.

.According to Fig. 3, both outputs (ends) of transmission line 3 are used in the device. If, however, only one output is needed, then the second segment (pos. 22 or 23) of output line 3 can be removed.

According to figure 4, the device contains

5 input 24 and output 25 acoustic ducts (made of piezoelectric material), fixed relative to each other with a gap 2 by means of gaskets 26. Information is extracted from the acoustic duct 25 by the output transducer 27

(Surfactant in an electrical impulse). After amplification by the amplifier 28, the output signal is supplied to the executive unit 5.

In the meeting zone, the input surfactants 12 and 13, generated by the input transducers (sources) 15 and 16, form the total surfactant 14, the amplitude of which is greater than the gap 2, and therefore with its crest strikes the output acoustic duct 25 and gives rise to the surfactant 29 and 30 in it (shown dotted line) extending to both sides of the impact site, including to the output transducer 27.

In the presented example, the SAW 13 has a high frequency (due to the filtering properties of the input converter 16). This ensures that the surfactant 12 and 13 are in phase (in order to produce burst 14) in phase.

The size of the gap 2 exceeds the amplitude of the largest surfactant 12 and 13, but should not exceed their sum.

At frequencies quite realistic for the indicated purposes, of the order of 10 MHz and a propagation velocity of 1.5-3.5 km / s, the amplitude of the SAW, commensurate with the half-length of the acoustic wave, will be not less than 0.2 mm.

When the transmission line is made of a material that supports the reaction of self-propagating high-temperature synthesis, in particular, from a TiNi alloy, the opposite temperature fronts 12, 13 are the carrier and information transmitters. The temperature in the zone of their meeting rises and becomes sufficient (taking into account the scattering gap 2) for excitation of the same reaction in the output line 3 propagating in the TiNi alloy at a speed of the order of 2 cm / s.

The operation of the device has two remote control spaces 15 and 16 and is as follows.

From control panels 15 and 16, the decoupling units 8 and 9 are instructed to carry out the required technological operation by unit 5, while the charges 11 are triggered and the plates 10 strike detonation pulses 12 and 13 with a shock. If the timing of the commands from both panels does not exceed the specified limit (the time of passage of one of the pulses 12 and 13, line 1), then the detonation fronts 12 and 13 meet within the length of line 1 and form a total burst 14, which can cause the detonation of output line 3 at a distance of 20 through the gap (or gasket) 2 from input end 7. If pulses 12 and 13 are generated at the same time, and their propagation speed along the length of line 1 does not change, then the burst will be in the middle of lines 1 and 3. Otherwise, it will shift towards a later pulse or a section with a lower speed disseminating information.

Executive unit 5 is triggered

after it detonates the portion 2C of the output line 3.

If the command is randomly (or intentionally, but not authorized) from only one remote control (or from both remote controls, but with an unacceptably large difference in time), detonation transmission to output line 3 will not occur, because the amplitudes of each of pulses 12 and 13 are

5 separately is not enough for this. For authorized (permitted) operation, instead of the triggered input transmission line 1, one of the backup ones (pos. 17-19) is used.

0 The device is suitable for carrying out other technological operations. For example, for photographic recording (by means of photographic recorder 5), the orientation of the missile (welded or reinforcing) plate

5 after passing beyond the control section of the flight path (behind the sensors 15 and 16 of the passage of the given section of the path), a strictly specified distance, moreover, regardless of the inevitable technological spread of the speeds of movement from sample to sample. This is possible due to the fact that the distance 20 of the burst 14 carries information about the flight time of the known base between the sensors 15, 16 (i.e., about the speed) and that the output line 3, in comparison with the input line, is used with a lower average the speed of information dissemination, and in some cases with a decreasing gradient of the delay time

0 in the direction of exit 4. Thus, when the sensor 1 b is placed first when registering a slower plate, burst 14 shifts to the left (the length of section 20 increases). And since

5, the average speed of propagation of the information pulse along line 3 is lower than on line 1, the output command for such a body is issued with a greater delay, which allows the lower-speed plate to reach the boundary of photographic recording (narrow field of view of the high-speed photographic recorder 5) together with a faster and faster thereby equally effectively registering bodies in a wide range of speeds

5 movements.
