Greenhouses, of course, not a fad or fashion, and suffered many a necessity. After all, these buildings, covering a plot of land of glass or plastic, allow * not only early to plant the seedlings in the ground, but also (no less importantly) to protect emerging plants from acid rain or any kind of “evil herbivore”. Special demand from the population use collapsible greenhouses. However, produced by the domestic industry options mostly far from perfect, inconvenient and usually prohibitively expensive. Here and master gardeners-gardeners in their plots all sorts of designs from scrap materials where lead foil, a nail, a Board homegrown clip. Construction work flimsy, “perniciously” not withstand even one season of operation. But… Every spring the people with the tenacity of a tight dried-up film (the other being at hand at that time somehow is not) skeletons of their teplichku-greenhouses.
ARCHED GREENHOUSE
Gradually accelerates since the beginning of the “great war” in Europe, the US military machine required a constant feeding of “raw materials” — new projects and orders. Moreover, fighting constantly threw up new and new reasons. After not too successful performance in Norway and followed the fall of France, the evacuation of the British from Dunkirk, it became clear that any fleet in dire need of strong air cover, to ensure that staff pre-war anti-aircraft guns could not. The Americans wanted to solve the problem fundamentally, creating a six-inch anti-aircraft gun, arming her cruiser. It is clear that the new super-aircraft guns required a high rate of fire and good mobility, not to mention the obligatory fire control systems. “Project” has drawn many more millions and on for months — perfect for the military-industrial complex.
Furniture manufacturer of plain (uncoated ahah!), the DSP completes its finish. Although this is a simple, but important step, which largely determines the appearance of the finished product. For finishing can be used adhesive tape, textured paper, cloth (linen, cotton) and veneer. The veneer self-adhesive film the most simple. The workpiece is cleaned from dust. Cut a strip of “adhesive” with margins, 5-7 mm; it remove the protective paper and film is superimposed on the detail and smoothed to remove air with a rag or a rubber roller.
The designers of the Department of track-laying tractors (known as the Department of “200”) of the Kharkiv locomotive plant them. The Komintern (KhPZ) built in 1936 heavy artillery tractor “Voroshilovets” on the basis of the original, but irrational in the scheme, laborious to manufacture and maintain chassis. Later, in the design process of the T-34, they came to the conclusion that because of the proximity of the traction-weights, power, and mobility it is advisable to develop heavy trucks based on the chassis of a modern medium tanks. This unification was beneficial and production.
I designed the machine addressed to the farmers and owners of summer houses with auxiliary water supply system, key units of which are a water source (river, lake, well or borehole), water tank electric pump Yes. From analogues this development is characterized in that in addition to performing its main function — control the electric pump makes it quite successfully solve tasks of protection of objects. This unusual flexibility is achieved not by complexity of an electrical circuit device, and by quick-change sensors, which are not only submersible multi-level electrodes and photoresists or thin, working on the rupture of the wire.
