SU5563A1 - AC magnetic rectifier - Google Patents

Description

The necessary equipment of each radio receiver working with cathode lamps is a battery, which is characterized by its fragility. If this is replaced by batteries, the latter require charging, which cannot be produced from alternating current without a rectifier. The existing electrolytic and hollow (lamp) rectifiers do not differ in great amenities for radio amateurs: first because of their low useful return (the electrolyte is heated and evaporated), and the second because of the high cost and fragility of the cathode lamps used in them. A mercury rectifier due to its high cost is not available to the mass radio amateur. The proposed electromagnetic rectifier is designed to fill this gap and allow the radio amateur using alternating current to benefit the most by charging the batteries or, without using a suitable filter for the rectified pulsating current, to do without them. In addition, the proposed electromagnetic rectifier is also intended to

for use in other technical fields, as it can be designed for different capacities.

FIG. 1 of the schematic drawing shows a longitudinal section of the proposed electromagnetic AC rectifier; FIG. 2 and 3 are longitudinal and transverse sections of the glass primer with contacts (on an enlarged scale) and in FIG. 4 diagram of connections.

In a cylindrical metal box 1 (Fig. 1), two coils 2 and 3 are insulated against the walls of the box by an insulating paper layer and separated by a metal disk 4, which prevents the electromagnetic field from one coil to another. The coils consist of a double winding laid in three layers, with the primary winding 5 consisting of thin insulated copper wire, and the secondary winding b - of insulated nickel-nickel or rheotan wire with high ohmic resistance m. Primary and secondary windings are wound on both

coils in one direction, whereby the ends of the primary windings of both coils are connected so that the direction of the passage of w, its current in the primary winding of one coil is opposite to the direction of that in the primary winding of the other, or, as shown in the wiring diagram (Fig. 4) , the primary and secondary windings of coil 2 are wound in one direction, and coil 3 in opposite directions. During winding, the coils are impregnated with an insulating adhesive substance so that they represent a solid solid mass. Between the coils, the glass switch capsule 7, divided by a partition 8 (Fig. 3), is placed into two separate halves in the central hole of the metal disk 4, in which nickel contact plates 9, 10, 11, 12, 13 are isolated separately from each other. , 14, 15 and 16. These plates in pairs (9 and 10, 11 and 14, 12 and 13, 15 and 16) are interconnected by a sheath, with lead wire for each pair, which are connected to the contact screws 17, 18, 19 and 20. The space between the lead ends is filled with an insulating mass 21. Both capsule halves, from which The air is inflated to / from the volume by the finest chemical pure soft iron dust. The most advantageous switch capsule sizes are established empirically. The box 1 is closed at the bottom with a metal lid 22. An opening 23 serves to attach the box to (e.g. wooden) base. At the top of the box 1, six contact screws 17, 18, 19, 20, 24 and 25 are fastened, arranged in pairs and isolated from the box. A hollow contact screw 26 serves to pull the wire, which is soldered to it in a cone 27. Other parts: 28 - ebonite bushing; 29 ebony washer; 30-nut to strengthen the contact screw; 31-lock nut. Wire fastening.

A small battery or a battery of cells 32 is connected to the contact screws 24 and 25 (Fig. 4), which excites constant, opposite electromagnetic fields in windings 2, 5 and 3, 5. When connecting wires from an alternator to contact screws 18 and 19 a small part of the current, the passage w, it in the branch along the windings

2, b and 3, b, creates in the winding 3, b the power lines destroying the electromagnetic field created by the winding 3, 5, and in the winding 2, b creates power lines increasing the electromagnetic field of the winding 2, 5 (to achieve this effect the design of the apparatus for a given power, respectively, calculates the diameter, length and resistance of the wire, as well as the number of turns of all windings and the electromotive force of the battery), whereby all the iron filings in the capsule rush upwards and create contacts between the plates 9, 11 and 13, 15. Direction re current will be: screw 18, plate 11, plate 9, screw 17, through the device, reclaiming rectified current, screw 20, plate 15, plate 13 and screw 19. When changing the direction of the alternating current, the electromagnetic field of winding 2, 5 is destroyed and increases such in the winding

3.5, due to which iron filings strive down to the ground and create contacts between plates 10, 12 and 14, 16. The direction of the alternating current will be: screw 19, plate 12, plate Yu, screw 17 through the device, screw 20, plate 16, plate 14, screw 18, etc.

The subject of the patent.

1. Electromagnetic rectifier of alternating current, characterized by the use of a glass capsule with indented contacts in a corresponding number, in the airless space of which iron filings are placed, intended to close the corresponding contacts when moving
