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.
INSTEAD OF DRILL — FILE
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…
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. It can be used to scan the same documents and prepare them for sending via e-mail.
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.
The method of circular broaching increasingly used for cutting the teeth of bevel gears, such as differential drive axle of the vehicle. The essence of the method of machining the workpiece cutting tool of a large diameter with radially arranged cutters. This technology is one of the most productive methods of manufacturing straight bevel.
The design and construction of the “Bumblebee” creative team “Rise” was based on microalloy design V. Barkovsky, V. Vinitsky and Y. Rysuke described in “MK” (see: 1969, № 6, 1970, № 3, 1970, № 10 and 1971, No. 6). This well made and for the first time in the country is stable flying machine of this class was exhibited at the Central exhibition NTTM 74 and was awarded a silver medal VDNH. Schematic diagram, basic dimensions and technology are critical components of microstoria differ little from those recommended in these articles, so we will consider only the scheme of “Bumblebee” in three dimensions and focus on the changes that have been made in the process of finishing and flight testing of the apparatus. Outset: we had the opportunity to use a number of ready-made components and parts from decommissioned planes and helicopters, which, on the one hand, some changed the look of our machine, and with another — has greatly facilitated the work: eliminated many labor-intensive operations, used aircraft normal, good fasteners, and so on.
Not so often we have to meet on city streets the car “coupe” or “convertible”. However, at the dawn of its existence, almost all cars were just that — open, with soft rising tent. In the future, the Foundation of the world fleet amounted to more prestigious and therefore more expensive cars with closed bodies. Well, coupe and cabriolets became the exception and, to the surprise of okaloacoochee the public, again significantly more expensive.
