Device for the determination of a ship in dock at the time of docking

The present invention relates to a device for determination of position of a ship in the dock at docking, based on the principle of reflection of ultrasonic waves from solid bodies in water. The device includes two pairs of transmitting-receiving converters (1), (1') and (2), (2') of an ec...

Zusammenfassung:	The present invention relates to a device for determination of position of a ship in the dock at docking, based on the principle of reflection of ultrasonic waves from solid bodies in water. The device includes two pairs of transmitting-receiving converters (1), (1') and (2), (2') of an echo sounder, each of which is connected to a separate indicator (5) and (7) of the echo sounder through a bi-stable switch (4), (6), while the both two-position relay elements (4) and (6) are connected to only one multivibrator (3).
