The tragic outcome of the Russian-японскоq war aroused in naval circles many contradictory opinions about how to be newly created Russian fleet. Considerable attention in these debates and discussions was placed on submarines.
Seed stations and seed agro-laboratories often calculate “manual. Manual labor is unproductive and tedious, especially if you need to count a large number of seeds. Counting on 10 thousand grains of wheat takes about three hours. And to make a mistake during manual account easily. However, this operation can be replaced by a method of weighing, but due to the difference in sizes of the seeds of error in this case reaches 30%.
Not to say that after the First world war, the British did not think about the problems of a future war, but their reasonable ideas are embodied in a metal surprisingly slowly. For example, the Admiralty issued an order for a new patrol and guards of the court only after their predecessors came almost to a complete standstill, having exhausted their resources. As a result, by the time of Hitler’s attack on Poland “mistress of the seas” had only six small patrol ships of the “Kingfisher”, and three were in the same building.
Fighter FIAT CR-32. The plane, which will be discussed, for the five years preceding the Second world war, was a symbol of Italian fighter aircraft. Small, nimble, he observed the conflicts that arose in South America, in China, in Africa, in the middle East. And in Europe is also not without “Italian fighter”—so in most cases called FIAT CR-32 in various countries around the world.
August 11, 1933, adopted the worker-Peasant red Army adopted a new medium tank T-28. Production began at the Leningrad plant “Red Putilovets”, one of the oldest and most experienced companies in the production of artillery, tractors, locomotives.
Burned a soldering iron, remained unfinished design… to Get out of the situation will help the soldering iron-impromptu. Cut out a 2-mm fiberglass charge, shape and size of a soldering iron. To provide two holes for ersatz heater, which works fine 10-watt resistor type sew-10 resistance 1 kOhm. It is necessary to connect a “wire-wrap” (about this method of installation, see the journal “modelist-Konstruktor” No. 4’2001), missing in the holes in his conclusions, the power cord burnt the soldering iron (as insulation it is desirable to use heat-resistant “sleeve”).
Long-range bomber Tu-16. Large-scale development of high-speed jet bombers, long-range flight, which began in the USA after the Second world war, could not remain unnoticed in the Soviet Union. A year after the publication of American requirements for such aircraft (in late 1946) to the design Bureau of A. N. Tupolev, Ilyushin and Sukhoi began the design of machines with the same parameters.
The first time I saw “Polonaise” in the picture. He was standing on one of the Central squares of Warsaw, surrounded by a dense ring of spectators. Interest in the yacht and its captain, engineer and journalist Krzysztof Baranovsky was extremely well-deserved. The first among the poles and the thirteenth in the world, he skirted “an old cannibal” — Cape horn — solo.
By the end of the First world war the British Navy had a fair amount of patrol type “flower”, but at the end of the 1920-ies it became clear that these hastily built ships will be developed very quickly. Therefore, the renewal of the composition of forces escort and protection, the British started ahead of time.
Today, when in any toy store you can always find a not too expensive radio-controlled models of cars, their availability would have to completely replace trace model. However, practice shows that the latter is still very popular in the children’s centers of technical creativity with circuits. There is still continuing work on creating a new highway model. The fact that they remain a very fertile subject to technical creativity, as you can make them without complex machinery and without expensive materials and components.
