As you know, the cost of electrochemical cells has increased significantly. Therefore, many owners of portable radio equipment are beginning to use batteries. And they must be timely and properly charge. Of course, when the apparatus used a bit (and besides, it is all the same type), the problems with no charge. After all, to get a good charger (memory) for a renewable source of electricity in a single “radioimage” is much easier than, say, to ensure the viability and flashlight (and it 2хД-0.55 C), and all-wave receiver (5хД and 0.26 D), and tester (Sht-0,06). In addition, note that the proposed market memory in the majority of the road is not very reliable, is designed only for a certain type of batteries, and a strictly fixed number of elements.
UNIVERSAL BATTERY CHARGER
When among students who have mastered only the basics of the original automodelisme, comes to talking about the class of simple machines, rubber motor, it is submitted immediately think “sophomoric”. They say, in the age of radio, heavy duty electric motors and internal combustion engines are very popular and widespread at the time the class is now an anachronism and good except for exploring the world of car.
Mini makiki always use the boys great success. And for good reason! Small size, cost-effective, modern appearance, excellent performance — what more can you ask for? Maybe that’s why many of them roll up his sleeve so take tools. After all, if you try, you can do mokik, able to compete with serial two-wheeled machines. However, it is not very easy, but it’s worth it.
This mini-tractor, Y. V. BALABIN, Amateur designer from Moscow city Lotoshino, built from what was found in a garage at home, with friends, in a scrap yard. However, “Scarce” (as he called his mini-tractor) is in the extensive garage of craftsman privileged position. Despite the fact that next to him are still jeep “Hugo” mini-mobile “Colibri”, the mechanical horse and maintenance — first and foremost, and repair in the shortest possible time. But how else? “Baby” is in fact the breadwinner of the family of its Creator! Without him and the garden for planting potatoes treated, and the crop will not be harvested.
Locomotive PB-21 of issue, 1934. In the early 1930-ies the USSR had embarked on the reconstruction of Railways, in particular, the decision not to build cars with the number of axes less than four. Rolling stock was assumed to be equipped with automatic couplers and air brakes automatic. For the traction was designed and built powerful locomotives – freight and passenger FD IP. It was planned and the electrification of the Railways; it was built Сс11 electric locomotives, cargo and passenger vehicles ВЛ19. In addition, the Central lokomotivostroenie Bureau (CLPB) together with the plant “Dinamo” has designed a locomotive designed for pure passenger services. It was a very original car, not like any one of the locomotives of the time. Moreover, this engine was absolutely unique – a hitherto nothing of the kind in our country were not built.
19 April 1968 a joint resolution of the Central Committee of the CPSU and the USSR Council of Ministers “On creation of gas turbine propulsion for objects of armored vehicles” SKB-2 at the Leningrad Kirov plant (LKZ) was instructed to establish on the basis of tank T-64 a new car with a gas turbine power plant. The development of the engine was entrusted to the Leningrad NPO. Klimova. Gas turbine engine (GTE) with the same amount that diesel has developed a much greater capacity. This would allow the tank to achieve higher speeds and to significantly increase the maneuverability on the battlefield, to improve the management of the machine itself. Experience in the application of GTE Soviet tank builders already had, especially at the Kirov factory. In 1948 here in SKB turbine production under the guidance of A. Starostenko was the project of a heavy tank with this engine, but it remained a draft. When in 1955 LKZ requested the creation of a new heavy tank with engine 1000 HP — weighing up to 55 tons, with 130 mm cannon, began to conduct work in two directions: developed the options and a diesel engine (“object 277”), and GTE (“object 278”). Two prototypes of the GTD was designed under the direction of G. Ogloblina.
