Description

The proposed synchronizing device is intended to be used for an apparatus transmitting an image over a distance.

FIG. 1 shows schematically a sending apparatus with a synchronization device; FIG. 1 a, 1 b details of the device and in FIG. 1c is a partial pattern of current flow.

The rotation of the cylinder 3, mounted on the axis 2, in the same direction (clockwise in the figure), is achieved by means of a pendulum 83. In FIG. Figure 1a shows the mechanism that turns the oscillatory movements of the S3 into rotary, one-way movement of the axis S. This axis has a longitudinal groove, into which a protrusion enters the inner surface of the gear wheel 16 (Fig. 1 and 1 a). The gear wheel 16 can freely rotate around the S axis, but is connected to the wheel 16 by means of a pawl entering the depressions of the teeth of the wheel 16, the teeth of which are opposite to the clockwise movement. A gear S3 is tightly attached to the gear wheel 17, which is engaged with the wheels 15 and 18. The gear wheel 18, which rotates freely around its axis, is connected by a gear wheel .9, which has a gear directed in the direction of the clockwise motion, also by means of a pawl, which is pressed by a spring. Wheels 19 and 26 tightly mounted on the axle. Gears 15, 17, 18, 26 and 29 are equal in magnitude; Wheels 27 and 29 have a diameter equal to half the diameter of the wheels indicated and serve to reverse the rotation. The wheel 29 is connected to the axle 2 by means of a protrusion entering the groove of the axle. Let the tick move forward (to the right), then axis 2 to cylinder 3 will turn to the right (clockwise). The wheel 18 will freely rotate around its axis together with the pawl, which will slide along the teeth of the wheel 19, the wheel 19 will rotate in the opposite direction under the action of the wheel 29, turning also to the right. When the torsion moves backwards (to the left), axis 2 turns back to the right (clockwise), while the wheels will rotate in opposite directions to those that they rotated in the first case. The fluctuations of the tantrum are supported by two electromagnets 13 and

J4, fed from current source 1 and attracting two iron rods 24 and 25, fastened to the tank at the same angles — even at an angle of 60 °. The ends of the cores of both electromagnets are located on the same horizontal, from which the rods 24 and 25 constitute, therefore, an angle of 30 ° is the angle of deviation of the antenna. Electromagnets begin to act a little earlier than the moment when the master, having spent part of his original energy, is ready to deviate to the other side. This is achieved as follows: a rod 9 pivotally connected to a rack of non-conductor: carrying an elastic plate at the left end (for example, made of metal), and a non-conductive rod at the right end. a wheel 11 having protrusions and depressions around the circumference (Fig. 1) and connected with axis 2 by means of a protrusion entering the same axis. When the tooth of the right end of the rod 9 falls into the cavity, the left one will be pressed against the upper screw 7; : when the tooth of the right end goes around the wheel circumference (there are no protrusions, no cavities), then the left end will be located between the screws 7 and 8, when the same tooth is located on the ledge - the left end is abutted into the lower screw 8. Accordingly, the current it will fall into the electromagnet 13, it will not fall into any electromagnet, it will fall into the electromagnet 14, as shown in the diagram (Fig. 1c), where the numbers denote the same parts of the apparatus. The initial condition (the deviation angle of the matte from the vertical is 30 °) requires the presence on the wheel 11 of three cones and three cavities alternating, located at equal distances x (circumferentially) from each other, equal in length and occupying (each) on a circle of 30 ° and the number of degrees that the tilt deviates from the vertical, thanks to the action of the earth attraction. At the receiving station, the Q.linder is likewise given to the player by the iron.

P REDM ET and 3 o r r e ution.

A synchronization device for an apparatus that serves to transmit images over a distance characterized by the cumulative use of the following parts: a) a 23-cylinder equipped with two iron rods 24 and 25 inclined to its rod from different angles, which the arc is connected by means of a gear system with axis 2 (fig. 1) of the cylinder on which the transmitted pattern is placed, so that with each swing of the tilt axis the axis rotates at a certain angle in the same direction; b) the specified gear system for the latter purpose, composed of an average wheel 17, fastened to a primary, and two teeth 15 and 18 coupled to it, connected by means of dogs with gear wheels 16 and 19, the teeth of which are turned in opposite directions, on these axes, these latter axles are connected to each other by means of wheels 26 l 29 fixed to them to intermediate gears 27 and 28, so that the movement of one axis is accompanied by the movement of the other in the opposite direction and c) electromagnetic devices for keeping the rifle in motion, made up of two electromagnets 1B and 14, located on both sides of the rim, and capable of attracting rods 24 and 25 attached to the tiller, respectively, with the windings of the electromagnets attached to one pole of the current source and, on the other hand, to the puffers 7 and 8 of the automatic switch 9, whose axis is connected to the other pole of the same source, which switch is located at one end relative to the wheel 11 with hollows and projections sitting on the base and device 2, so that it can fall onto said depressions and protrusions by this end and rotate accordingly, touching the clevis 7 or 8.
