Union gypsum and cardboard. In modern homes and in the individual construction of partition, suspended ceilings often are made of drywall – this versatile material. The popularity contributes to the fact that it is cheap, non-toxic, flame retardant, suitable for different humidity conditions. In addition, be aware that this sheet of finishing material is made from eco-friendly materials. In essence, it’s a thin panel, which is a kind of sandwich, the outer layers which leaves special lining cardboard and an inner layer or a filler composed of plaster and some extra special components.

BATTLESHIP “ADMIRAL USHAKOV”
COASTAL DEFENSE BATTLESHIP “ADMIRAL USHAKOV”. Scale model 1:200.
One of the most famous ships of the Russo-Japanese war, the battleship “Admiral Ushakov” was laid on 22 October 1892 at the shipyard Baltic shipyard in St. Petersburg in accordance with the shipbuilding program in 1881, launched in October 1893 and commissioned in 1896. In addition to “Ushakov”, was built two sister ships — “Admiral Senyavin” and “General Admira Apraksin”.
CORROSION THREADED CONNECTIONS
During repair works of structures with steel threaded connections of the work items that have to deal with the complexity of their separation due to corrosion of the thread. These phenomena can be caused by the influence of precipitation, condensation as a result of temperature changes, as well as in cases of operation in different aggressive environments.
WELDING… WATER
I’m a longtime subscriber of your magazine, use a lot of printed in it. I especially liked the article “Fire… of water”, published in “M-K” № 7, 1980. The description made the cell, and it has become a necessary tool in my workshop.
CAR AMO F-15
CAR AMO F-15. Scale model 1:25.
Car AMO-f 15 (1924-1931) was the development of the Italian truck FIAT-151ter. The first ten cars were collected from 1 to 6 November 1924 and was presented during a demonstration on 7 November of the same year, on red square. All trucks were painted red.
THE FIGHTER-15
THE FIGHTER-15. Scale model 1:33.
I-15 is one of the best in world practice of aircraft construction of samples of a fighter-biplane – has been developed in 1933 in Polikarpov design Bureau. The scheme and design of the I-15 was a further development of fighter I-5, but had better aerodynamics and a much more powerful motor air-cooled M-25 (license reproduction of the American Wright Cyclone f-3). A characteristic feature of the I-15 was the peculiar form of the upper wing having the circuit “Chayka”, thereby reducing aerodynamic drag and gave the best view forward and up.
GARDEN, MAJOR
After the construction of cottage or garden house, as a rule, there remains a lot of unused construction material suitable for auxiliary facilities on the site.
For example, the remaining timber can be used for making stationary, capital bench. One of the variants of such design offers the Hungarian magazine”, Earmaster”. Everything in it is “solid”, massive; this bench is not afraid of any bad weather, will last a long time, especially if it is not installed on the ground, and on asphalt or tile a cement pad somewhere in a cozy corner of the house wall.
STIRLING ENGINE
The Stirling engine is a heat engine invented by Robert Stirling in 1816. It differs from the internal combustion engine because the fuel burns outside the engine, making it much easier to manufacture. There are Stirling engines that run from the heat of your hands, although they are a little harder to build. The Stirling engine would be a good addition to any collection of those who like to make things with their hands.
GARAGE-TYPE “SHELL”
The garage-type “shell” have already become usual for our urban yards. However, in many cases — for example, in the country — you can install a simplified shelter, make on to the motorist.
FIGHTER I-5
FIGHTER I-5. Scale model 1:33.
The history of this car, dubbed the I-5, began in the summer of 1927, when Polikarpov developed a preliminary draft of the fighter under the British motor Bristol “Jupiter” is one of the best in those years of power density. This gave the opportunity to provide good maneuverability and rate of climb. Technical Council Aviatrust Polikarpov suggested to consider the inclusion of a new fighter in the prototype development plan and approached the BBC with a request to present to him their tactical and technical requirements. Design And-5 plan had to be completed in November 1929: in October of next year, it was required to produce to the test.
