Compression, and adsorption refrigerators often fail due to the fact that they denied Electromechanical relays or breakers on the basis of the bimetallic plates. The first of them is used to trigger synchronous electric motors, serving a compression refrigerator system, and the second are the basis of the tracking systems and maintain at a predetermined temperature level freezer [1]. The reason for failure and the other is a burnout or a mechanical failure of the spring contacts in these devices. Ego especially applies to older models of refrigerators. And often you can see that, because of the insignificant, but hard to handle breakdowns (due to the lack of spare equipment) the throw is still quite usable machines. In the material made the attempt to remove such faults in household appliances.“SECOND WIND” OF THE REFRIGERATOR

Two LEDs with different color (e.g., red and green), you can build a simple indicator for voltages from 4.5 to 220 V. It is also able to determine the polarity of the source in the range 8-220 V. When measuring AC voltage, both diode glow, but if it is constant — lights one of them depending on the wiring polarity indicator. The scheme proposed by the Czechoslovak journal “Amaterske Radio”.
Once, while on vacation with an overnight stay in a tent on a wooded Bank of the river, found an annoyance: a portable TV operating off the car battery, bad was shown on the set of the antenna due to the weakness of the incoming signal. Then began experiments with aerial: spinning her this way and that, but to no avail. Then began to try to connect to the antenna and instead found in the boot of the wire. He was placed in different places, all sorts of curved loops, but otoh, too, almost gave nothing – UHF signal with a piece of wire was seen as bad.
In interior décor – be it a city apartment, rural or country house — most especially functional and decorative role plays different draping: all kinds of curtains; curtains and Drapes adorning the doorways; the tulle on the Windows and curtains. The latest must-have even in those homes where there may not be anything else. And that they are subject to all the variety of fabrics and devices. There is even a well-established division of curtains on certain types.
Flying clubs Directive of the Central Committee of DOSAAF of may 25, 1979 allowed to build gliders only on the drawings approved by the technical committees of local federations of hang gliding. Besides flying a self-built devices should be performed only after examination by the representatives of the technical commissions in the field. This decision was due to the need to ensure safety both during training and during sports performances and is intended to nullify the persisting injuries.
Etendard — his predecessors and successors. iavlenie nuclear weapons not only changed the balance of power in the world, but also determined the path of development of military aviation in the first five years after the Second world war. A priority for the countries possessing nuclear weapons was the creation of the heavy bombers to deliver nuclear bombs, and fighters to escort their bombers destruction of others.
It’s been over a decade since then, as avtomodelisty decided to make your sport all season and came up with kordovye model of the sleigh. Now, perhaps, it is difficult to name the author, the first such model: the necessity of introducing the lessons of the circles simple, affordable design that would combine the speed of production and the possibility to use the internal combustion engine, would the creative scope for the budding modeller and, moreover, would not be just “educational” (like, say, contour resonators), was clear to many.
The German Navy was engaged in an ultra-small boats only in 1944. Prior to this the Germans managed to capture a number of European States, without resorting to the use of underwater diversionary means. The only “small” submarine that was developed in the early years of the war, was V. 80. But it is not planned to use for combat purposes, this 4-person submarine was used only for testing balcerowski turbines. She had a displacement of 71/80 tons and a length of 26 meters.
