The drawing shows a diagram of the device.

The device contains three logical elements - first 1, second 2 and thirds 3, three-way distributors, made with springs. 4 backwaters. The distributor 1 is provided with a manual control button 5. The input channel 6 is connected to the normally open input 7 of the distributor 1, with the input 8 of the distributor 2 and with the normally closed input 9. distributor 3. Normally closed. input 10 of distributor 1 communicates with

connected to the second output channel 21, with its control chamber 22 and through a check valve 19 with its normally closed inlet 9. A normally open input 23 of the distributor 3 is in communication with the normally closed outlet 24 of the distributor 2.

The device works as follows.

When a signal is sent through channel 6, it passes to input 8 to output 1 7 of the distributor 2 to output channel 18, which is connected to a sound signal generator, for example, a siren (not shown). At the same time, the signal from channel 6 is fed to input 7 and output 11 of distributor 1 and further through inertial link 12 into camera 14 of control of distributor 2. At the time interval specified by the setting of throttles 15, distributor 2 is activated, which leads to the removal of the signal in channel 18 and applying a signal through the input 8 and the output 24 of the distributor 2 to the input 23 and the output 20 and to the channel 21 connected, for example, to an actuator (not shown). At output 20, the signal is memorized as it enters control chamber 22 and output 20 is connected to input 9.

By briefly acting on the button 5 of the distributor 1, the operator has the opportunity to re-apply the signal to the channel 18, when switching the distributor 1, the air from the control chamber 14 through the check valve 13

will be discharged to the atmosphere and the distributor 2 will return to the initial position for a specified time.

Repeated impact on the distributor 1 does not change the memorized signal at the output 20 of the distributor 3, the device returns to its initial state when the signal is removed in channel 6, For. Mule Invention
