Remember how in one of the Russian folk tales bear arc bent? Took two legs of the barrel at both ends and through the knee. For while it attempts, as we know, was not successful, note that to perform this operation, in modern technical language, it took him three working “element”: one rounding (knee) and two power (paws). The most modern devices for bending tubes and bars contain the same three elements. Usually they are mounted on a special table. There is a metal loop, which is inserted into one end of the pipe, a stationary roller — on it is bent, and the movable roller with the lever.

To various tool holders, cartridges and heads, clamping a working tool in addition to reliability, is increasingly imposed and such requirements as simplicity, convenience and fast-shift. It is these qualities in the first place and is distinguished by a new Chuck for horizontal boring machines created by young innovators Odessa plant of milling machines named after S. M. Kirov.
the heavier the car or the unit, the more powerful Jack is required for lifting during the repair in the workshop or in the field. But the more powerful the lift, so it is heavier, and this means that it will require more effort — those who it is intended… to save.
It happens that some of the most common types of fastening parts — bolt weakened, cannot withstand the load: the bolt is cut, the remaining upper portion in one part and lower in another. And if the top part of it to extract just enough to work the key, to turn the lower is usually the problem. For this you have to drill a hole in it, then tap to cut a left hand thread to screw in there another bolt or pin and then use that to Unscrew the stuck “stub”.
Simple attachment to the percussion pneumatic tools such as pneumatic type, 5K or 5K-MP offered by the innovator of the production Association “Znamya Truda” fitter V. Ivanov, allows you to execute some unexpected surgery — to cut through the metal.
Simple machine for the manufacture of a protective “shirt” to a milking apparatus. prepared for transportation created by the innovators Yanovskogo district Association of Lithuania. Usually they were transported in canvas bags or boxes that do not provide the required sterility and do not always meet the requirements of industrial hygiene and sanitation. In addition, such containers required after each use thorough disinfection with subsequent drying.
Probably there is no sector of the economy, which would not have developed or used bulk materials. And for most of these powdered products is the most insidious enemy — humidity. To get rid of her, used a variety of dryers, which despite their structural dissimilarity is used most often one and the same principle of dehydration — contact: the powder comes into contact with the hot surface inside the evaporation chamber of the installation. However, such contact is harmful to many materials because of the high temperatures they lose their quality.
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.
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.
