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.
HIGH-SPEED SCREWDRIVER
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.

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.
Central to the exhibition NTTM-78, dedicated to the XVIII Congress of the Komsomol, and the 60th anniversary of the Komsomol, very popular among the visitors enjoyed the section “Eureka”, in which he demonstrated unusual vehicles created by Amateur designers. Wheeled-tracked all-terrain vehicle “Arctic”, built as an electrician from Rybinsk Valery Medvedev, was one of those cars that arrived in Moscow on VDNH USSR “his way.” Yes, it was not a model but a live working machine, figuratively, “discontinued operation” in the household of his Creator. Summer and winter, heat and cold, hunting and fishing, just outside the city with your family or on urgent business drives this original machine designer. Already more than fifty thousand kilometers was “Polar”. The mileage is respectable, even for production vehicles.
Snow scooter “the little humpbacked Horse” — advanced single track sled with steering from the mountains for skiing on-piste slalom or downhill. In different countries such sleds have different names: “snow bike”, “snow horse”, “ski-Bob”, “ski-Doo” (“the snow flea”). And they are made variously depending on the purpose and conditions of operation.
Was close on the streets of big cities in many countries. Cars almost RUB against each other. The speed of the traffic flow often barely exceeds walking speed. But just watch — in a multi-bed machine sitting often only one driver, in the best case in society only passenger. The other places are empty. Then, maybe, you need to reduce the machine dimensions to one double-minicar, freeing up additional space on the streets thousands more like them?
Winter in our Northern lands long. Roads are not so thick, and those on time do not have time to remove snow from. It turns out that no trails of cars people here do not easy, moreover, often have to travel entirely off-road (e.g. forest wood) — recorded directly on virgin soil. However, the acquisition of a snowmobile, not everyone can afford, even the not-so-expensive—simple. So we have those who are able to make a machine with their hands, designing it according to your project under those parts that the craftsman. The snowmobile, which, the story goes, I was not the first (see “modelist-Konstruktor” No. 11 for 2004).
