City bus ZIS-155 production in 1949. The development and expansion of cities accompanied by the concentration of citizens in residential areas and, consequently, the factories in the industrial, has created the problem of passenger traffic, which could not solve a horse-drawn vehicle for personal use. And in the second half of the XIX century in cities there are predecessors of buses and trams, horse and steam-powered.
“After reading # 1, 1975 note”, Polihale”, I can not write about his former teacher, the head of the circle of technical creativity of the Chernyshev Lev Sergeyevich,” writes a reader from the village Krotovka Kuibyshev region, Liquor.
There is near Moscow, Serpukhov district, well-known vegetable farm “zaoksky”. Here, in high school, already DEA works student design bureaus, organized from the students of high schools teacher of Evgeny by Diligently. A quarter of a century he gave to the beloved work with children. Many of his pupils-modelers repeatedly took the first places of ka of the regional and national competitions were the winners of the all-Union competition; 12 masters of sports prepared them for this time. Experienced youth mentor bears the honorary title of honored coach of the RSFSR.
Music lovers understand the interest shown by people of different ages and professions to all new in the field of stereophony. The development of electronics and improvement on the basis of sound engineering techniques have enabled the lovers of house concerts to listen to gramophone records and tape recordings with a sound quality close to natural. Stereo replay system allows to obtain aesthetically the most complete and accurate representation of the executable composition, all the colors, the nuances that are sought to convey in a recording musicians.
Summer is a time of exciting tours for lovers of water tourism. However, it is not easy to reach the shore with a heavy backpack and kayak.
The idea is to make the car the most I had in those days, when “the Zhiguli””Muscovites” and even “the Cossacks” could be bought only after standing for many years in the queue.

Carrier-based fighter F4U-5/7 CORSAIR. In the annals of aviation are not many aircraft left in her mark. But it is to such aircraft include the American fighter F4U CORSAIR the Chance Vought company, which had a great influence on the outcome of the air battles over the Pacific.
allows you to quickly verify the health of the quartz resonators. Diagram of the device consists of a generator (T1), detector (D1, D2) and DC amplifier (T2). By connecting the quartz to the two terminals of the generator, the power on. If the resonator is OK, resistor R2 appears to the high-frequency voltage which is then fed to diodes D1, D2 for detection. Highlighted in this case a constant component opens the transistor amplifier stage. Load UPT serve milliammeter ИП1 and lamp L1. The glow lamp indicates the functionality of the quartz. But his activity is judged by the readings of the milliammeter. For the active resonator current is 70-90 mA, and for inactive — 30-40 mA.
Sports model missiles Ѕ6В champion of Russia S. Romaniuk (G. Uray) — a graphic representative of the aircraft’s so-called “Ural” scheme, the author and developer of which is a team of rocketmodeler city of Chelyabinsk under the leadership of the deserved trainer of Russia V. I. Tarasov. Its main feature — an extended tail cone. Its length is 115 mm. In the rest of the model is made according to fairly well-known technology.
The competition of the State Committee on aviation technology to establish the impact of a missile to destroy aircraft carriers was announced in September 1961. In the fight for the prestigious order entered OKB A. N. Tupolev, F. S. Yakovlev and P. O. Sukhoi. In the autumn of 1962 was held on advanced Scientific-technical Council, which commissioned the development of a conceptual design of the aircraft design Bureau of P. O. Sukhoi.
