SU30722A1 - Device for electrical telescopes - Google Patents

Description

In the author's certificate number 4135 describes a device for electrical telescopes using stranded cable. According to the invention, the ends of the cable cores at the receiving station are bent and the places of kinks located on the same plane are covered with a layer of zinc sulphide and strengthened inside an airless box, on the side of which an aluminum shell is made to transmit Lenar rays from the cathode tube towards the above zinc sulphide layer in order to obtain a transmitted image on it while passing photovoltaic currents through the conductors of the cable.

The author proposes a modification of his proposed device for producing electric binoculars for infrared rays.

The essence of the invention is that the cables included in the composition of these devices are shaped as short sections, the outer sides of which are covered with layers of selenium, and there are respectively lenses between the inner and outer sides, which serve to discard the images from binoculars items.

In FIG. 1-3 depict a screen in three projections; FIG. 4, 5-proposed device in two projections.

The device operates on the condition that the observed area is illuminated by infrared rays. It consists (Fig. 4.5) of two photographic viewfinders /, in which the opaque glasses with the image obtained on them are replaced by selenium double-sided screens.

This screen is placed in a dark chamber with an optical glass 5 at the top, into which the eye of the observer is looking. A hole is made in the front vertical wall of the chamber into which Lenar's output beam falls from the cathode tube 4 onto the screen.

The screen is made as follows (see Fig. 1-3): a metal frame 5 is taken corresponding to the size of the desired screen. In this frame, narrow foil plates 6 are sealed at a distance from one another, corresponding to the magnitude of the image point. The ends of the wires 7, are drawn between these plates. isolated from each other and from foil plates, but with peeled ends.

The length of these wires should correspond to the screen thickness. On the other hand, these wires are also framed in a frame similar to the first frame.

The screen thus assembled is like a segment of a multicore cable, enclosed on both sides by frames, to which the current connection terminals fs, nk are attached. On the one hand, this collected piece of ka-, bel is covered with a thin layer of photochemical selenium. This side of the screen, kzk, has already been noted, directed towards the rays from the object examined in the viewfinder. The other side is first rubbed with a fine powder of graphite, and then covered with a thin layer of zinc sulphide.

FIG. 4, the dotted line shows, in addition to the cathode tubes, element 8 for feeding the selenium screen. This element is included minus to the frame covered with selenium, and plus K - the frame covered with zinc sulphide. The electric current from the battery enters the metal frame with foil plates and from them through the illuminated infrared rays selenium enters the protected ends of the wires. With the help of foil plates, the current is evenly distributed over the area of the selenium screen. Graphite, being a conductor, freely conducts current from

wires into the foil plates, and through them into the metal frame and further back into the battery,

 the second screen, covered with zinc sulphide, falls, invisible to the eye, a Lenar ray, which causes the zinc sulphide to glow. This beam disintegrates across the screen in proportion to the currents passing through the conductors, thereby causing the illusion of the image transmitted by selenium.

The main purpose of the device is observation at night and generally in the dark.

The subject matter of the invention.

Modification of electric binoculars for infrared rays, consisting of two receivers described in the author's certificate No. 4135, characterized in that the cables included in these devices are shaped as short segments, the outer sides of which are covered with layers of selenium, between the inner and outdoor. The sides of these segments include sources of direct current for passing current through individual wires of cables, and lenses are placed in front of the outer sides, which serve to discard images from observed objects in the plane of these sides.
