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.BANK — IN THE CASE
In the Treasury of homemade, made from scrap materials made of NEMA some tips for using the empty cans. Maybe somebody can use this option is the simplest soap dish or wall offices for storage of small things in the home workshop. As is clear from Fig. As a preset you can use any tin, Read more…
Of all the plumbing tools in the “conservative” design remained still, probably only a hammer. However, the innovators of the production Association Zhdanovtyazhmash found the opportunity to improve it. They created multi-purpose bench hammer. It can rightly be called a harvester — informed so many unusual functions, it can now make thanks to the extra built-in details.
Lately in the aviation modeling widespread flying models, radio controlled, including helicopters. For the first time such a model was demonstrated in 1959 at the all-Union competition of S. Vorobyov. To control the flight he applied the principle of changing the alignment of the apparatus. After a year in the championship, in the background, a helicopter appeared Borisov with an aerodynamic rotor drive. In 1964, at a match meeting of the athletes of Moscow and Leningrad, he introduced the concept of B. Yuriev new model with tail rotor. However, the car was “raw” and, unfortunately, remained unfinished.
It’s hard to say which is harder: to put on or take off hard a spring ring serving as a seal between the walls of piston and cylinder internal combustion engines, compressors, pumps, certain pumps. The more valuable a simple tool created by young innovators at the Pavlodar tractor plant. It makes it easier to perform both operations.
It is generally accepted that a drill is the main tool DIY, hobbyists tinkering something with their hands for home, for family, as well as the main means of mechanization of labor-intensive processes in the creation of makeshift equipment. It is not surprising, because thanks to various auxiliary or additional devices drill can replace even some machinery. For example, a drilling machine, which can produce very simple equipment, published in the Hungarian magazine “Earmaster”.
Photoswitch is a widespread element in various automatic systems, protective devices, meters, etc. depending on the tasks the system is triggered by a photocell can be made instantly (for example, the turnstile in the subway), or via a predetermined gap (the Elevator doors). And in some cases rapid changes in illumination is necessary to analyze the situation and prevent deployment if it turns out to be false.
THE F-80 SHOOTING STAR. The story of the creation of the F-80 started in late spring of 1943 at Wright field, where the main designer firms Lockheed (Lockheed), Daniel Russ (Russ Daniel) met with representatives of the command of the U.S. air force. The meeting resulted in an official letter in which the firm was asked to develop a fighter jet under the English engine.1B “Goblin” company Havilland De (De Havilland.) These engines are planned to produce on the industrial base of the American company Allis Chalmers (Allis Chalmers). Last long time was trying to develop his engine, but 1943 she abandoned her fruitless attempts and have purchased a license for the construction of N. 1B.
