SU43205A1 - Essential tool for studying the rules for preventing collisions at sea - Google Patents

Description

Instruments are known for studying the rules of divergence of ships, consisting of a chamber with interchangeable signals installed in it, given by electric bulbs. In the proposed in-kind manual for studying the rules for preventing collisions of ships in the sea, the warning lights are covered by the frosted glass training, creating the illusion of night visibility and making only the lights of the oncoming vessel visible without showing its silhouette. In addition, the manual is equipped with a rheostat, with the aim of creating the impression that the lights are moving and approaching.

In FIG. 1 depicts the proposed in-depth manual, front view; FIG. 2 - the same, side view from the side of nests for plugs; FIG. 3 - a cross with reinforced light bulbs; FIG. 4 5 and b-set contacts and plugs; FIG. 7 - in-depth manual with a camera; FIG. 8 - another form of performance of the allowance.

An excellent guide for studying the rules for preventing collisions of ships in Mopis consists of a flat box (Fig. 1 and 2) with a ground glass / in its front part, inside which a wooden crosspiece is inserted {Fig. 3) with through holes; in the back of the holes of the cross of the top (218)

Cartridges of 2 light bulbs from a flashlight.

In front of these holes for colored light bulbs 6, 9, 11, 12, 13 and 20, colored glass pieces are inserted.

Through the holes in the cross, the light from the lit lamp is projected as a bright circle on frosted glass 7.

On the sides of the crate there are slots 3 (Fig. 2) for inserting plug 4 (Fig. 4-b), including one of the combinations of lights being lit.

The power of the bulbs is made through a transformer dwarf directly from an AC power supply or, if there is no lighting network, directly from a flashlight battery.

Approximation and removal of the lights is carried out by a rheostat changing the brightness of the light of the burning lamps and placed in the back wall of the box. FIG. 4-b shows a plug 4 forming contact with a contact spring 5 attached by a screw 7.

In some cases, for individual training, camera 8 can be attached to the device (Fig. 7), creating the illusion of observing fires through binoculars.

In another form of the implementation of the allowance (Fig. 8), the box is made

disclosure that facilitates the replacement of burnt out light bulbs. The combination of lights is turned on by pressing the corresponding button 9. The buttons are shown arranged in two rows. In addition, the device can be equipped with a rheostat 10, giving the impression of moving and approaching lights. The device has a suspension / 7 for fixing on the wall.

The proposed advanced manual provides for the incorporation of 42 combinations of lights, in accordance with international rules for preventing collisions at sea, and is intended for thorough training in these rules. Learning views are only lights, not the silhouette of a ship, which teaches, in a classroom environment, to quickly reveal the actual situation surrounding the ship at night. The device also allows easy checking of the degree of learning, and the training can be conducted simultaneously by a whole group.

The subject matter of the invention.
