Description

Apparatus for optical signaling in Morse code by means of an acetylene flame is known.

In the device according to the invention, in order to obtain flashes of various durations corresponding to the points and dashes of Morse code, an additional burner mounted on a separate nozzle was used, which, when burned together with the main burner, produces a shorter .

In order to obtain different intervals between flashes corresponding to the signs of one letter and flashes referring to two adjacent letters, the gas source is connected to a constant-volume chamber on which two-tube burners are mounted, on one of which a valve is installed that covers this tube to obtain a larger interval between flashes and opening it to obtain a smaller interval.

FIG. 1 schematically shows the proposed device, in FIG. 2-5 its various positions.

Unlike the known optical signaling apparatus, in which acetylene from the pressure regulator (source) enters the flashing part through a single tube of constant diameter and in which there is one burner connected by a single tube to the flashing part, in the proposed device the pressure regulator It is connected to the flashing part - a chamber of a constant volume of the inverter with two tubes, which, in addition to the main burner G, is equipped with an additional burner DG. If acetylene from the inverter chamber passes only into the main burner G, then the duration of the flash will be S. When acetylene enters from the inverter chamber, not only into the main burner, but also into an additional burner, the duration of the flash will be S ,. Since the exit of acetylene (gas) through several holes occurs faster than through one hole, then

5 2 and, therefore, with a certain difference between S and S, it is possible to distinguish with an eye a long glimpse of 5i (dash) from a short (dot) glimpse of S. The length of the interval f between letters in Morse code. always more than the interval / between characters (dots and dashes) in the letter. If the acetylene from the RD source to the IF chamber is opened and closed at the right moments via an additional tube, then a short or long interval can be obtained. In this case, when acetylene (gas) enters the IF chamber through two tubes, its filling time / 2 will be less than the time t, in the case of opening one main tube. With a certain difference between the / and / „, it is possible to distinguish with the eye a long interval / from a short interval 4 This will allow the Morse code to be separated among themselves.

In order to open and close the valves on the above tubes at the right moments, it is necessary to have such a device that could convert the pressure force of acetylene into a translational or rotational motion. The IF chamber is connected by a tube with a chamber, the upper wall of which is formed by a leather membrane. When the chamber is filled with acetylene, the PC chamber is also filled with acetylene, raising the working membrane of the PM. The PM membrane has a stem with a pawl coupled to the XP ratchet. When the membrane is raised, when acetylene enters the chambers of the inverter and the PC, the rod goes up without turning the ratchet Xr, as the dog just drops over its teeth. When the stem is raised, the return spring is adjusted and the GRP spring, the purpose of which will be explained below. As soon as acetylene starts to flow from the inverter chamber into the burner, it, passing through the upper chamber of the VC, creates a pressure equal to the pressure in the PC chamber. Then the spring of GRP, compressed when raising the stem, will send the stem, and with it the PM membrane, to its original position. Doggy when lowering the guitar,

capturing the ratchet tooth Xp rotates the latter at some angle.

On the same axis with the ratchet Xr, there are two KKS code wheels to the CCP, which open and close the valves allowing the passage of acetylene from the RD regulator to the IF chamber and from the latter to the additional burner DG.

The CT valve, which opens and closes the access of acetylene from the RD regulator to the IF chamber, is controlled by a CCD code wheel.

The valve KS, which opens and closes the access of acetylene to the auxiliary burner, is controlled by a KKS code wheel.

FIG. 2 shows the device in the first position when the fire is off. Acetylene comes from the regulator RD in the chamber of the inverter in one tube. The filling time of the IF camphor is equal to / j. From the inverter chamber, the acetylene enters the PC chamber and lifts the PM membrane together with the stem, which compresses the GRP spring. Code wheels KKS and KKT are motionless and valves KS and KT are closed.

In the second position of the device shown in FIG. 3, the fire is burning. Under the action of the elastic membrane of the PM opened the output valve VP from the frequency converter of the frequency converter, and the acetylene enters the chamber VK. At the same time, the pressure of acetylene in the chamber of the inverter decreases to atmospheric, and at the moment of equality of pressures in the chambers of the VC and PC, the spring of the GRP returns the PM membrane to its original position. In this case, the dog on the rod turns the ratchet Xp, and with it the code wheels KKS and KKT, which open the valves KS and KT. Since acetylene first enters the VC chamber, and then into the burners, the CS valve opens before acetylene starts to exit the burners (main and secondary). Therefore, not all acetylene passes through the main burner, because a part of it through the valve CS enters an additional burner. From here, the ignition1 will be S ... The CT valve, although open, but acetylene from the regulator of the regulator does not enter the inverter chamber, since the valve of the lever of the actuator is in the upper position, thus closing not only the tube connecting the inverter with an RD controller besides the valve / {T, but also the tube connecting them through this valve.

In the third position, shown in FIG. 4, the fire goes out. At this moment, the clanan-p step VP, lowering, closes the exit of acetylene from the IF chamber into the burners, thus opening the access of acetylene from the RD controller to the IF chamber through two tubes (main and additional), since the CT valve is open. The filling time of the inverter chamber with acetylene in two tubes is equal to / - / j (see position one). Stock.Membrane PM goes up and compresses the return-adjusting spring VRP.

In the fourth position, shown in FIG. 5, the fire is burning. Acetylene from the inverter chamber enters the VC chamber and then into the main burner G. Before acetylene enters the burner and lights up, the stem of the PM membrane under the action of the spring of the GRP returns to its original position (see position two). In this case, the stem dog turns the ratchet, and with it the code wheels. The valves CT and CS are closed. Acetylene goes only to the main burner and the duration of the flash. In the fifth position (or the first position - see Fig. 2) the fire goes out. The pressure in the inverter chamber drops to atmospheric. The valve lever VP goes down, stopping the passage of acetylene into the burner and opening the access of acetylene from the regulator to the regulator in the inverter chamber.

Subsequently, the operation of the device is repeated in the same order, starting from the position of the first one. In this example, the simplest combination of dots and dashes was shown: one dot and one dash (dot - the second position, dash - the fourth position), which corresponds to the letter “L in Morse code. In this case, the characteristic fire will be as follows: S + i, + S, + t, T.

If the code wheels have other cuts or are set relative to each other at a certain angle relative to the zero point of the ratchet wheel, the combinations of points and dashes (or, equivalently, small and large flashes of light) will be different.
