Through the closing contact 24 and the opening contact of the button 22 of the relay 9 of the film driver for the film projector 1

0 becomes self-locked. When the transition period expires (7 seconds), time relay 11 triggers, closes its closure contacts 10 and 47. Pin 47 blocks relay 31 of time of film projector 2, and closure contact 10 connects magnetic starter 6 to power supply bus I. When a magnetic starter is triggered, its closing contacts 12, 16 and 1 are closed and the opening contact 13 is tripped.

0When closing contact closure

15 sound foci lamp 17 is connected to power supply bus II. When closing the contact 21, the ignition unit 20 is connected to the first output of the block 4 pi5 tant projection lamps

Through the first switching contact 14 of the toggle switch 15, the closed closing contact 12 of the magnetic actuator 6 of the projector 1 and the closed opening contact

0 33 magnetic actuator 26 the first switching contact 34 of the toggle switch 35 of the film projector 2 closes the first and second inputs of the 4 L-block unit of projection lamps. The power supply unit 4 of the projection l-amps is generated and feeds the supply voltage to the ignition unit 20 and the lamp 19. This voltage in the ignition unit 20 is converted into the high-voltage pulse of the lamp 19 The lamp 19 pierces and ignites. The voltage across its terminals drops to an operating level (20-22V).

The demonstration of the filter from the film projector 1 to the screen begins, during which it is necessary to charge the next part

5 film projector 2. When the first signal mark appears on the screen. At the end of the displayed part, the projectionist presses the first button 43 of the projector 2. This activates the film detector drive 29 of the projector 2 and applies voltage from the power supply bus VI to time relay 31 and the second output of the remote switch 3. The latter switches its contacts 46 and 48 by unlocking the time relay 31 and preparing the time relay relay 11 for the projector 1 to shut off.

When the relay 29 of the film drive path is turned on, its closing contacts 28 and 44 are closed. The closing contact 28 connects the electric motor 25 to the bus I of the power supply. The film is moving.

Through the closing contact 44 and the opening contact of the second button 42 of the village 29 of the drive of the film path of the film projector 2 becomes self-locking.

After a transition period (7 seconds), the time relay 31 triggers, closing its closing contacts 30 and 45. Through the closing contact 30, the magnetic starter 26 is connected to the power supply bus I.

When the magnetic starter 26 is actuated, its closing contacts 32, 36 and 41 are closed and the opening contact 33 is opened. The latter turns off the power supply unit 4 of the projection lamps. The projection lamp 19 in the film projector 1 goes out. The closing contact 36 connects the sound-reading lamp 37 and the power supply bus III. The closing contact 41 connects the ignition unit 40 to the de-energized power supply unit 4 of the projection lamps.

When the closing contact 45 of the time relay 31 closes and the closing contact 46 of the remote switch 3 is closed, the relay 11 of the film projector 1 is blocked. At the same time, its closing contacts 10 and 47 open. The closing contact 47 unlocks the relay 31 of the movie projector 2 time.

The closing contact 10 disconnects the magnetic starter 6 from the power source bus I, but since a capacitor 7 is installed in the coil circuit of the magnetic starter 6, the magnetic starter 6 is turned off for the time required for switching operations (40-45 s).

After the delay time has expired, the magnetic starter 6 turns off and opens its closing contacts 12, 16 and 21 and closes its opening contact 13

The closing contact 16 switches off the sound-reading lamp 17 from the bus III of the power supply. The closing contact 21 turns off the projection lamp 19 from the de-energized power supply unit 4 of the projection lamps. When the opening contact 13 of the magnetic starter 6 of the film projector 1 is closed and the closing contact 32 of the magnetic starter 26 of the projector 2 is closed, the power supply unit 4 of the projection lamps energizes the charging voltage through the closing contact 41 of the magnetic starter 26 to the ignition unit 40 and the lamp 39. This voltage the ignition unit 40 is converted into a high-voltage pulse by the breakdown of the lamp 39. The lamp 39 breaks through and lights up. Voltage on her

terminals reduced to operating level (20-22B).

The film begins with a film projector 2 on the screen.

When the film emerges from the film path of the film projector 1 with the second button 22, the relay 9 is disconnected. The latter opens its closing contacts 8 and 24. The closing contact 8 disconnects the electric motor 5 from the bus I of the power supply. The closing contact 24 opens the self-blocking relay 9 of the drive of the film path. Cinema projector 1 is ready to charge the next part of the film.

The end of the session is as follows.

in a way. At the end of the plot, for example, when a film is shown from a film projector 1, the toggle switch 15 is moved to the neutral position, the power supply unit 4 of the projection lamps and the sound reading are turned off

lamp 17. The projection lamp 19 is turned off. At the end of the record on the film projector 1, the projectionist by the second button 22 turns off the relay 9 of the drive of the film tube of the main path, thus disconnecting the electric motor 5.

If it is necessary to reproduce the phonogram at the end of the plot, the toggle switch 15 is shifted to the position in which the first and third terminals of both switching contacts are closed. In this case, the power supply unit 4 of the projection lamps is turned off, turning off the projection lamp 19, and the acoustic reading lamp 17 continues to be lit. At the end of the phonogram, the toggle switch 15 is moved to the neutral position. When the film leaves the film path with the second button 22, the relay 9 of the film path drive is disconnected, thus turning off the electric motor 5.
