A lot of trouble delivers the design of internal stairs, for example, the attic. For convenient large marches, as a rule, not enough space and they are very steep, which is dangerous, especially for older people.
In one of the rooms of the old Czechoslovak magazine offered a curious compromise that we present to our readers. Down, this design resembles a regular staircase, with steps which are quite comfortable to climb. Folded as it rises and does not occupy much space, face the horizontal “door” leading to the attic. The whole design operates the motor, turn on the bottom button.
MAIN BATTLE TANK “ABRAMS”
Large-scale work on designing a new main battle tank began in the USA after the termination in 1970 of the joint with Germany development of a promising tank МВТ70. In February 1972, the United States was formed the operative group, composed of military and representatives of the companies-developers. Their task was the formulation of a concept of the future tank ХМ1. The result of the work of this group was “Requirements for the material,” published in August 1972. A new tank was developed on a competitive basis. To participate in the competition, the Pentagon chose two companies: Chrysler and “GM”. 18 July 1974 was signed with them the contract to develop and manufacture prototypes of a new tank. Under the terms of the contract, prototypes were to be presented for testing by early 1976.
GARDEN PATHS
Garden paths at the cottage or the mansion was just as necessary and sidewalks in the city. As a rule, these tracks build from individual concrete slabs with sizes of 400×400 mm and 800×800 mm and a thickness of from 50 to 200 mm And these boards are offered to buyers such as large factories of reinforced concrete structures, as well as small firms. Preliminary calculations showed that the cost of all materials necessary for the production of one tile, four times less than the price of the finished product in trade organizations. So isn’t it better to make them yourself, especially not so this work is difficult. DIY garden paths— more work for the soul than just physical labor. Besides the economic benefits gives strength and promotes creative thinking. Well, if you feel tired, take a break (even for a few days) on any plate.
HANGER FOR SHOVELS
No matter how carefully posed in a corner storage room in the garden or summer cottage the rakes, spades, forks, hoes — they are still getting in the way: take the place of the fall.
Right-angled triangles from the Board, attached on the wall next to the pantry, will serve as a hanger storage selkhozinvest after work or the end of the season.
T92 LIGHT TANK
Received in 1966 the US Army light tank М551 Sheridan made a splash among specialists. The case of aluminum alloys, 152-mm gun — launcher ATGM “Shillelagh”, the ability of the transport aircraft and parachute landing — it was all tanks for US, and for most light tanks the rest of the world a new word in the design and tactics of application. However, the value of these innovations were controversial, but it is not even that… All of the above is well known to many history buffs tanks. Much less known is that if the “cards lay” differently, the American army would get a completely different, though no less interesting light tank T92.
NOT THE SPRING AND GRAVITY
Conclusion of any country fence is the gate. Often achilladelis provide simple devices that automatically close the gate after you pass through them — this steel springs, and rubber bands, and weights-balances… However, all these “machines” are not without their drawbacks, and the main one is that they all require additional elements like springs, rubber bands, kettlebells, etc. However there are devices that do not contain any further details, and the closing force is obtained due to… gravity.
PLASTIC GREENHOUSE
Living in Siberia, without a greenhouse on the site not to do — the summer is short and not always warm, and vegetables home you want. Therefore, sooner or later, every owner of even a small piece of land think about the construction of the greenhouse.
Plenty naeksperementirovavshis with different kinds of film, come to the conclusion that its apparent low cost is deceptive: the material is ephemeral, every year you have to disassemble the greenhouse, and equip it again. In the end, I want something more substantial.
MOTOMOBILE FOR ALL
Motomobile is an individual vehicle, in which, as the name implies, combines the qualities of car and motorcycle. Needless to say, unite the advantages of these vehicles with the greatest possible exclusion of their shortcomings.
“Ruta” — is extremely simple, very comfortable, highly economical and inexpensive to manufacture machine designed for individual use as a city or a car, and cars for truckers, capable of carrying a driver with a passenger and not too bulky Luggage. Fits well as “Rue” as a vehicle for the disabled and the elderly.
THE FLOAT IN THE TANK
Usually in the cistern of the toilet in an actuator of a shutoff valve on the lever set hollow plastic float. If its integrity is violated, it fills with water and stops working. As a consequence, continuous noise of flowing water, condensed moisture on the tank, dampness and mold.
BUZZER
Buzzer on digital circuits switching on/off of electronic devices with power supply of 12 V.
In the car a lot of devices that are included in the operation key or switch. To control the inclusion of a device only by clicking a mechanical switch (which when the machine can not hear) or visual position of a key (which is not easy in motion).
