SU49306A1 - Astronomical tube for the joint determination of the width of time and azimuth - Google Patents

Description

The main geodetic works relating to cartography include, as a necessary part, the astronomical determination of the latitude, longitude and azimuths of the source punctures and sides of trigonometric networks. In addition, astronomical determinations of latitude, time, and azimuth are also necessary under the conditions of various expeditions. Such astronomical definitions are also very important in some areas of military affairs, and so on.

Astronomical and geodetic works in their field parts take place in expeditionary, hiking conditions and in terms of organization and technology they are quite complex and require both an astronomer with considerable theoretical readiness and practical skills.

The processing of the results of astronomical observations is carried out in the winter cameral period, takes a lot of time and requires, again, a highly qualified specialist. Thus, obtaining final results is detached from field work and delayed for a long time.

As can be seen from the above, the rate of astronomical and geodetic works is small, so that the cost of these works is quite high, why

It is desirable to achieve a reduction in the cost of astronomic-geodesic robots, increase their pace, simplify and accelerate the office part of the work, simplify and mechanize their observational part, etc.

The present invention is intended to overcome these disadvantages and allows for the following:

1) to obtain all the quantities of interest at the same time (jointly), and not as a result of a number of separate consecutive observations;

2) to simplify the preparation for observations because of the unnecessary preparation of the ephemeris of many different stars;

3) to cancel most of the calculations, since all that is necessary is obtained directly in the form of samples in circles (horizontal, vertical, and hour);

4) to simplify maintenance and make it available to a specialist of average qualification, etc.

To the author's testimony of V. G. Maslaev, dated July 21, 1935 (Ref. 173384).

On the issuance of copyright certificate published August 31, 1936.

In order to map a path when performing a given route, it is very important to be able to determine the location on a map as quickly and easily as possible. The proposed device shown in the drawing is intended to quickly plot the position of, for example, an airplane on a map using two known bearings.

Radio stations are equipped with sockets 7 on the map. Two plug legs 2 are inserted into the indicated sockets; they are supplied with rubber threads 3 or wire spirals made of thin wire, the free ends of which are connected by thread 4. Thread 4 is passed through the ears 5, in the center small (80-100 mm in diameter of a transparent disk 6. The circumference of the disk has an uphill rim 7, provided with depressions through each degree, into which the disk is divided. Along the O-180 ° line, the outline of the vessel or plane and 8.

just place the disk 6 on it so that the thread 4 runs straight from the center to the fixed radio stations and does not have kinks near the edge of the circle. The equipment of tablets and navigation charts by the proposed device solves the above problem of quickly determining the location and direction of movement in two bearings.

The subject matter of the invention.

A device for determining the location of a moving object according to the signals defining two well-known bearings, characterized in that a flexible, stretching thread, for example, made of rubber, is used at its location at the coordinate points on the map (the bearings are a relatively moving object is known), which thread is threaded through the pin 5 in the center of the disk, equipped with crevices in its limb, into which the thread is threaded, in order to determine the month by the position of the disk center on the map opolozhenie moving object, when the thread freely without kinks passes through appropriate slots, the position of which is selected according to the already known Pelengs.

DESCRIPTION of the device for automatic registration of sea currents.

To the author's testimony of V.I. Chernysh, dated July 31, 1934 (Ref. 151837).

On the issuance of copyright certificate published August 31, 1936.

The invention relates to a device for automatically registering sea currents by fixing on a photosensitive paper the position of the device body fitted with feathering relative to a magnetic meridian.

In the device proposed, the magnetic needle is mounted on a platform longitudinally moving inside the cylinder, the inner surface of which is covered with photosensitive paper, on which the relative magnetic arrow is recorded using a light beam from an electric bulb rigidly connected to this arrow.

In FIG. 1 is a side view of the device; FIG. 2 is a longitudinal section of it and FIG. 3 and 4 longitudinal and transverse sections of the device details.

On the inner wall of the hollow cylinder / strengthened by means of springs 2 (Fig. 2) photosensitive paper 3, grafted on the abscissa axis into rumba, and along the ordinate axis - on the time division. Inside the cylinder / there is a magnetic system suspended by a slit thread 4 formed by a magnetic needle 5 rigidly articulated with a cup 6, inside which is placed an electric lamp powered by a battery 8. In the lower part of the cup there are polished in the form of a mirror and angled 4U to vertical metal mirror 9 and narrow (diameter 0.5 mm) tube 70 (Fig. 2 and 3). Magnetic arrow 5 is mounted on the axis 24, reinforced on the pad, to which silk thread 4 is attached, slung over the rollers / 2 and winding onto the drum / 5. This drum is mounted on the axis J4 and is set in motion by means of a clock mechanism / 5.

To change the photosensitive paper 3 or to remove the cylinder / parts from the top, the cylinder has a hole with a hermetic cover J6. Cylinder J is placed in a casing / 7 of a flow-optimized shape, equipped with a tail part / 5 (Fig. 1). The device body has a throat, hermetically closed by a cover 25 with a rubber gasket 19. To ensure the vertical position of the cylinder 2, this cylinder is suspended from the cover on a hinged suspension 20. Case / 7 is equipped with a lever 2 / for fastening the cable on which the device is dipped into water.

For making observations, the pad 7 / is lowered to the stops 25 and the photosensitive paper 3 is inserted into the cylinder 7. Then, having closed the cylinder 7 with the cover 76, lowered it into the housing 77 and screwed down the cover 25, after which the housing on the cable is lowered in the INVENTION
