We have already talked about how the heavy cruiser became a favorite class for American sailors Large 10 000-ton ships could not be better suited for action on the oceans, where distances between bases was a few thousand miles. Therefore, the new Maritime conference assembled in London in 1930, overseas admirals fought for them as hot as in battle. And in the end succeeded: the United States was able finally to overcome the “mistress of the seas”. Even in the same class of ships, but most (as it seemed) interesting. Americans are “knocked out” for himself the right to have 18 heavy cruisers, while the British were allowed no more than 15, and the Japanese only 12. It all looked just fine, but in fact the Treaty of London recorded this at the moment the situation. The United States already had in service or on the stocks of 16 units falling in the “severe” category, and not all of them came out good and strong. The seventeenth was the “Vincennes”, which was built on existing project “new Orleans”. In the end, the further development of class room for maneuver remains very little — only one ship. Then you’d have to wait until your 20-year term will serve the first of the “Washingtonians” and they can be replaced.

With a slight rustle of the blades of the propeller model took to the air. Passed one circle, two, three. All this is familiar today in many circles of our country guys raise flying model aircraft with electric motors. However, some features of this device are forced intently follow him. Whether unusual for a rechargeable element wing — flaps, or confidence, a kind of reliability of the flight. After all, we are accustomed to the fact that the power of the motor just enough to keep the model in the air.
Military transport aircraft, being developed by “Aerospatiale” (France), “British aerospace” (England), DАSА (Germany) and CASA (Spain), intended for the carriage of goods weighing up to 32 tonnes, including 120 equipped troops, helicopters an-66 Tiger, NH-90, as well as artillery guns, in particular, howitzers М110А caliber 203 mm jet systems of volley fire. The power plant consists of four gas-turbine engine with propeller fans. The aircraft is equipped with a system of refueling in flight. Four wing-mounted nodes possible suspension assemblies refueling aircraft fuel in flight or containers, electronic countermeasures.
Looking through the model magazines for the last couple of years, you’ve probably noticed a sharp change in the appearance cord racing model aircraft. They have disappeared, it would seem, absolutely necessary stabilizer. And it’s not just a tribute to another sport fashion. See what kind of patterns are models of the prize-winners of competitions of different ranks, increasingly they are flying wings. Some of the appearance of these devices, resembling a kind of pancake, not like others talking about a more modern and rapid appearance of the model. But form form and racing microplane primarily sports equipment. And from this point of view, a flying wing has many advantages over apparatus of a conventional circuit. What? First, the “tailless” much easier. Typical “representative of the” new school weighs 150 g, while an old over 220 g (without engine). So, significantly reduces the time during which the model accelerates to maximum speed. Yes, after stopping the motor it is hindered by the faster. And this win precious fractions of seconds! Less weight leads to less tension cord control. The pilot is getting easier: even at high speeds the centrifugal force is not so much to strain the hand.
Mixer intended to receive the concrete mixture or cement-sand mortar. The performance by volume – 15 two-gallon buckets of a mixture in the ratio of 1.5 buckets of cement + 4.5 buckets of sand + 9 buckets of gravel (water not included) in one batch in for 15 minutes (5 minutes: to load, mixing and unloading). Structurally, the mixer consists of three nodes: capacity (mixer), suspended cradle, bed.
Electrocaloric (Fig. 1) consists of a spindle with a bobbin and flyer, electric motor, transformer and switch. The metal shaft of the spindle (Fig. 2) a console fastened to the rack on two bearings: with a free hand for him to put on the reel-spool and the pulley, which is secured by a nut-lamb. On the other hand the crank shaft is drilled a channel to pull the yarn and the welded flyer.
Battery (battery) of a mobile computer (laptop) holds 700 – 800 cycles charging/discharging: approximately three years of active service. With a bad battery the laptop loses its main advantage is ensuring autonomy. And then there is the problem of replacing or repairing the battery. New costs 3-4 thousand. The restoration of the old service station is estimated not much cheaper.
You never thought about the fact that your car racing has a good gyro, and not one? But they are made and put into place your own hands! Their role is carried out by the engine flywheel and gear wheels. In the not-so-small mass and size, the frequency of their rotation is so large that such is not always seen in the “adult” technique.
At the beginning of world war II the threat of Japanese invasion on the island of New Zealand growing by the day. The country was in danger, not having any modern weapons. Under these conditions, the Public Works Department has proposed a draft tank on the basis of the tractor D8 Caterpillar (“caterpillar”). The army was interested.
Looking at this unusual backpack, shown by the team of the Leningrad regional Council of tourism, you catch yourself thinking: how had not thought of before? Indeed, in a normal backpack, even properly Packed, all belongings in a heap: to get to the bottom, you need to shake everything. Now imagine three separate bags: one stacked products, other auxiliary equipment, the third — warm clothes; then all pulled together by the lacing and shoulders! On the middle section reinforced wide webbing or machine: go to a small hike — you can do this middle.
