Perhaps the most part, even far from the sea and naval Affairs readers will agree that the word “submarine” the first thing comes to mind is the thought about German. Dark grey body, emerging from the waves and drowning defenseless transport goods or people torpedoes or shoot his target from a cannon. What can you do Germany and its leaders have done much to leave this not very honorable, but terrible mark in both world wars.
This year — 100 years since the birth of S. P. Korolev, the father of the Soviet space program, the outstanding designer of the first artificial satellites and spacecraft, the Creator of Russian strategic missiles. His interest in rocketry could arise even during his studies (he graduated in 1930 Bauman.Bauman), and finally strengthened with the creation of the public organization gird (Hoppy the study of reactive motion), where he developed and tested the first Soviet rocket “gird-9” and “gird-X”.
When machining on milling machines it is frequently necessary to install the item at a certain angle. An original device for this purpose was shown in NTTM-78 military innovators. This unique milling angle for the inclined fastening of machine parts. It consists of a base, a graduated sector and the movable hinge strap.
One of the ways of dealing with skvoznyaki in a modern apartment is to install a rubber door sealer, available in hardware stores. But here’s the thing: if you provide a large preload, the door because of stiffness of the rubber will close hard. If you reduce the tightness will worsen the tightness. I propose Read more…
Working with a file always takes a lot of time, particularly where its course is restricted: in a deep hole, in a curved channel. Here come to the aid of a power drill. Hold its cartridge needle file with round cross-section or chip of a round file with machined shank: spiral cut works great not Read more…
Military experts, specializing in the use of armored vehicles on the battlefield, is among others one burning question. In military conflicts, in anti-terrorist operations are widely used armored personnel carriers, infantry vehicles, armored cars. Often on the March, the nomination for appointed positions, with participation in the patrol raids, reconnaissance actions on their roofs, the buildings, the sides are soldiers infantry, paratroopers, reconnaissance, preferring the roofs of armored compartments and parlors, the places inside the body. They, not without reason, believe that there is more likely to survive if the car gets into an ambush or a RAID on the mine and will start firing from all sides, or even hit from a grenade. This is especially justified if the movement occurs in an open area. But to find the enemy off the roof easier than using glass or prismatic devices, besides being in a confined space.
Multifunctional device consisting of copier, printer and scanner (hereinafter, MFP), it is useful not only for home or office desktop. In practice, there are times when a copier, printer or scanner is required to literally “here and now”. For example, they are often necessary for a “hike” in state institutions. The device is so popular in modern life, when visits to bureaucratic offices require copies of the documents becomes irreplaceable.

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).
About the craftsmen of the rural settlement of the Highlands of the Yaroslavl region, I had occasion to write more than once, and what a surprise it was that the reserves were not yet exhausted. With the local game warden Jevgenijs Picolinium relationship work immediately. It was felt that man can not sit idle. Every year, a new car, be it a tractor, ATV or buggy.
The denser the stack will be the builders of the concrete, the stronger will be the monolith. That is why in industrial and housing construction in the manufacture of precast concrete structures there is a need “compacted” cement mixture. At the Yaroslavl plant “Red lighthouse” for such purposes, developed an Electromechanical vibrator. In contrast to existing devices is not superficial, and deep submersible instrument: it can affect the entire thickness of the layer of concrete, compacting it well.
