In October 1950, the design Bureau of the Detroit Arsenal (Detroit Arsenal Tank Plant) began designing a new tank, designed to replace the M47 medium tank. Will not be superfluous to note that the latter at the moment has not yet been adopted. It is obvious that the leadership of the U.S. army was aware that the M47 is not promising fighting machine, as largely based on constructive solutions tank M26, created at the end of the Second world war.
The draft of the new machines put the design of a skilled heavy tank Т43. He was inherited by the new one-piece streamlined housing is u-shaped, which is close to oval in cross section. American experts believed that this form of housing equal to the thickness of the armor will provide better ballistic and mine protection in comparison with traditional designs. In addition, the new medium tank, the diameter of the tower overhead in the light maintained the same as on a heavy – 2159 mm. And this despite the fact that he would be armed with 90 mm gun, not 120mm, as Т43. This solution allowed to make the walls of the tower, a significant slope and to abandon a developed stern niches. In General, the tower had the shape close to a hemisphere, which significantly increased its sharedetails.

ELECTRIC CARS OF THE USSR
Rare video about the production of electric vehicles in the USSR. Be sure to see to understand that at the time we were “ahead of the rest” in development of such technologies.
In the USSR in 1971, was planning to release a standard electric car! And this at a time when the term “lithium polymer batteries” even though the project did not exist, and batteries for electric vehicles was a big part of the machine. Now of course this documentary looks naive, if you look at the latest designs of type Honda Insight, Toyota Prius or Tesla Roadster.
HAND TOOLS
Hand tool – a tool that does not use any other energy except human power. Now on the market of building tools wide selection of hand tools is the screwdriver, files, mitre and many more.
Buying one or the other hand tools, make sure that produced it is reliable and well known firm, and that the delivered screwdriver, drill (and other hand tools) reliable suppliers to avoid fraud.
Video games

BINDING CASE
Since its inception, the binding was seen as an important commodity property of printed materials as an essential criterion for its evaluation. Essentially “clothing”, for example, workbooks or calendar, the cover becomes part of their decoration, a kind of means of characteristics of the publication bears the imprint of an era, and a certain style. He may be rich or poor, sophisticated or original, subtle or funny. Depending on how printed products will be decorated externally, directly depends on its relevance and uniqueness.
CANDLES
The invention of candles may refer to the ancient Egyptians. They lowered the reeds in animal fat and burned them. Wax candles create a romantic atmosphere, light when no lights are an integral part of religious ceremonies. But how to make candles in the 21st century?
Many centuries candles are the perfect decoration of the interior. Classic cylindrical (conical) form of suppositories inserted in the original bronze chandeliers, creating an atmosphere of elegance and comfort. Recently it was suggested many new and interesting solutions to composite construction decorative candles: they are made in the form of figures of animals and birds, fir cones, fruits, houses, vases, etc. Candles began to be multicolor, embossed patterns, etc.
FRESH FLOWERS
Breeding roses is not as difficult a task as many imagine. With minimal effort growing roses is possible even in cold climates.
Winding rose will grow up striving for the light. They need support because they have no tendrils to cling to itself. Curly shoots of roses grow in the horizontal direction. It is on these branches the buds appear. Shoots can be strengthened in a horizontal position, if you tie them to a support such as a fence. For the rose gardens with arches and walls suitable variety Zephirine Drouhin, which produces large, fragrant flowers and a few sharp stems.
MIRROR
The forerunners of modern mirrors were polished pieces of obsidian and bronze discs. But the Romans were placed under the pieces of colored glass plates, leading to better reflect the surrounding objects.
In the 13th century, with the start of production of vessels made of transparent glass, glassblower poured inside a tin vessel, and when it cooled down, smashed the vessel. These curves fragments and served as a mirror.
CRUISING THE “BORDER”
Concluding which lasted a quarter of a century the history of the cruisers of the “new generation”, it is appropriate to think about “what would happen if…”. Sense for the main “if” is easy to guess: the absence of artificial restrictions of the Washington and London treaties that led to all countries to create their ships in a very rigid framework, especially in displacement. As we have seen, although not twins they were not, but the choice of artillery of the main caliber was almost automatic: eight inches for a “heavy” “Washington” units and six for their “light” counterparts.
CRANBERRY
In old Europe it was believed that cranberry – Russian berry, owes its origin to Russia. We must assume that this opinion arose through the activity of Russian merchants, carting around the cranberry to European countries whose populations are less prone to gathering. In the 10-12 centuries, excluding Russian merchants, cranberries were brought to Europe via the Vikings. In the Nordic countries, mariners and soldiers often took this berry as a cure for many ailments and vitamin as a delicious dessert.
