Usually mention the proverbial fifth wheel. However, some automakers use a formula, reflected in the name of our material. They really believe the fourth wheel in the car superfluous. Judge for yourself: unlike a four-legged three-legged stool on an uneven base does not wobble (remember school: three points can be spend a plane, and thus only one). Consequently, the frame “trehalase” will be more rigid and the car will be more lightweight and durable (and hence cheaper).
On the roads of Kharkiv, there was one car with the familiar letters of the COI — “Club eternal”. The automotive laboratory of the centre of scientific and technical work is headed by the laureate of many competitions NTTM Valerie L. Taranukha. This time in the neighborhood of the letters KVP caused the index of the TX-200. And the car, unlike all previous is built via a three-wheeled configuration, using the whole back of the scooter T-200. In this part is the main “rational” of the new machine, created the “Club of the eternal search for” V. L. Taranukha, together with the candidate of technical Sciences Y. S. Hojnowski. Hence the index — TX-200.
On our market there are now a lot of imported bikes with a large (over a dozen) number of speeds. But fascinating these machines are, perhaps, only youths. Experts understand that to take full speed full still impossible: difficult even to choose the correct gear and often switch them on the go is not only tiring but also unsafe. Because switching is required usually in difficult driving conditions or cornering, when the hands should firmly hold the steering wheel, and one of them is necessary to manipulate the lever. As you know, the cars are only 4 — 5 speeds, and the drivers prefer to upgrade to automation.
Because of the diversity of karts, built by athletes and produced by the domestic industry, the most advanced in design and for a number of technical characteristics is currently cards KS-76 designed in TSKTB DOSAAF of the USSR and manufactured by the Leningrad production Association “Patriot”.
Innovators of the Moscow machine-tool plant named after Sergo Ordzhonikidze developed an unusual screwdriver, equipped with a booster with transmission ratio 1 : 6. This means that one turn of the handle of the screwdriver results in six turns of the tightening screw. Such a screwdriver can be successfully used in small-scale and serial manufacture installation and other operations on mechanical parts, fitting and mounting work with mounting screws when fixing various caps, visors.
The development of the untold wealth of the North, Siberia and Far East is impossible without specialized vehicles. Many more years will have to transfer the cargos to remote parts of the country in the most difficult off-road conditions, deep snow, hummocky ice, by freezing the swamps and reeds ducts.
— Can not be? Well, look! — Short, stocky man bent low over the open trunk of a small yellow car and disconnected the battery contacts, took from his pocket the usual flat battery 3336L and licking to be sure shiny contacts are not “hooked”? — connect them to the wires of the motor.

Remember: to become the creators of the new need to develop the spirit of critical and attentive attitude to the phenomena, and then your present passions in the future will be the Foundation of your life.
Laboratory and technical creativity SGPTU № 33 at the Leningrad Association “Svetlana” is already known to our readers. Dozens of original designs, has earned diplomas at many exhibitions, inventors ‘ certificates, rationalization proposals introduced, giving a substantial economic effect, the laureate of the medal is the result of the work of LTT for several years of its existence.
The best Amateur-built glider, took part in the competition “Dombai tops” in 1978, was named “Sokol-2”. Its Creator — Leningrad master of sports V. D. Mikhailov, a renowned specialist in the design and making of yacht sails. So it is understandable his desire to use when constructing the glider, the latest achievements in the field of sailing. As a result, the quality of the dome “Sokol-2” had no equal among the devices flying over the Caucasian peaks.
