Their proposals presented to the company “Grumman”, the “North American”. “McDonnell-Douglas, General dynamics and Ling-Temko-out”.

Born of fire. As it is impossible to imagine a good porridge without butter, and high-quality mortar without lime. It’s a common binder finds wide application in construction. Lime is produced by calcination of sedimentary rocks, the main component of which is calcium carbonate and perhaps magnesium oxide, When the content of magnesium oxide more than 7% of lime is called magnesia, with a smaller it presence of calcium. In the construction using both lime. These rocks are tight, clean and dolomitized limestone, chalk, shell limestone and other Rocks should not contain more than 8% clay impurities (the fewer the better and cleaner lime). Roasting is performed at a temperature of 900° — 1200°C up to possible the complete removal of carbon dioxide, that is, the decomposition of calcium carbonate with the release of carbon dioxide and formation of calcium oxide or so-called lime-quicklime.

In the design of the transmission of a snowmobile “Buran” has a centrifugal accelerator, the CVT. During intensive operation of the snowmobile this node will wear out within two seasons. First fail the movable cone of the variator and Cams-weights. The reason for such a rapid wear of the mentioned parts is quite simple: the Cams abut in the troughs of the movable cone, thus squeezing out deep dents. When starting the snowmobile from the place when the engine begins to develop momentum, the Cams are unable to smoothly get out of these depressions, there is a sharp jerk of the belt variator, which leads, among other things, and rapid wear of the belt. In short, almost every season you have to change the movable cone, centrifugal accelerator and a belt.
I want to share with the readers one very simple method of drilling holes in the glass, which I was taught many years ago Professor N. A. Artemyev.
