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.THE PACK, NOT THE BASKET
Usually writing or computer table is a basket for unwanted papers and other debris. And how without it? In my opinion, much easier and more practical to have on hand for these purposes, a simple plastic bag, preferably with handles. In stores now them as packing material abound. And to hang the bag on a Read more…
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.
Exhibitions amazingly beautiful decorative pieces of KAPA compete even with the amber jewelry—seafood and resinous prehistoric forests. Cap (in other words—influx) is a growth on the trunks of trees that represent an anomalous development of the wood. Once in the hands of a master, he is transformed into a work of art decorative art: original planters and flower vases, unusual dishes and bowls, pencil holders, ashtrays. All of these items look as if created by nature itself, and people only found these treasures in the woods, spying them in intricate swellings on the trunks (by the way, is detrimental to the tree).
The so-called unusual mechanism established at the Irkutsk industrial College for tightening heavily loaded threaded connections of large diameter. Anyone who has had to screw up the nut of the bolt, under the head of which is placed a rubber washer must necessarily have resorted to little tricks: when it’s getting on bad, just click on the head — it will dig into the rubber, the bolt will move forward and rotate the key will be much easier. Paradoxically, this principle was put to the Irkutsk innovators in the basis of the work of this mechanism. When tightened heavily loaded threaded connections of large diameter Jack allows you to stretch the bolt or stud within the elastic deformation that provides the subsequent free rotation of the nut.
