The model, which will be discussed in this article warmed the soul to generations of young sailors. In the distant postwar years, and even in the sixties, such a boat could be found on store shelves. From many toy counterparts his distinguished acting steam engine in the bilge – in the furnace was burning real flame to heat up and boil water in a small steam boiler, humming quietly, pushing the boat forward, two small jet of thin tubes. On a boat it was impossible to look without admiration – he was so real! And easy the soot from the burnt fuel on the surface of the cutting gave this amazing little machine is truly a “combat” look. The greatest effect was achieved in the twilight, when at full speed in the Windows of the wheelhouse, it was possible to observe the flickering glare of the flame.

Do not consider it shameful to use a good development designers and lovers they share the magazine. But, armed with their interesting ideas and technical solutions, and the very creative approach. So for the treatment of potato between the rows was made cultivator-Hiller. He arranged for motorcycle scheme, when working on (cultivator or Hiller) is located between the two running “in the tracks” wheels: guide (“sulker” from children’s pedal cars) and leading (of the scooter Tulitsa).
France withdrew from the First world war among the winners, but the state of Affairs she was far from rosy. The country suffered huge human and material losses, the civilian economy was set back by several years ago. Did not add optimism and the Navy, the main disadvantage of which was its poor balance. Particularly depressing look of the cruiser: the most modern and the only combat-ready units were German trophies.
The knives or Strug indispensable when machining curved surfaces. To make them simply — it will only have an old file with a length of about 200 mm. In the first file you need to termoobrabotki. Soshlifovat previously a small area, gradually heat the file evenly along its length until, while in ground place appears red-brown film of oxides, after which the file is cooled in water or air. This heat treatment will reduce the brittleness of steel, while maintaining the hardness necessary for cutting edge on plow.
“Battleship”… Who do not know this simple yet exciting game! Polished by many generations of pupils, it reached perfection and it has only one drawback — “shots” of the battle are easily detected in the classroom, as opponents and then whisper: “D4!” — “Choke!” “E5!” — “Hit!”… If the teacher hears the losers are both the enemy.
The Soviet designers managed to create a fighting self-propelled installation SU-85 with a full booking, able to deal with medium and heavy enemy tanks with high maneuverability and passability. Offices and engine and transmission were the same as the T-34 tank. This allowed us to complete the crew without retraining. Unitary munitions and gave an opportunity to reduce its numbers to four, which made a more concerted actions of the crew in battle.
Motorists made electronic blocks of ignition, as a rule, according to the classical scheme consisting of a high voltage source, a storage capacitor and a thyristor key. However, such devices have several drawbacks. The first of them is low efficiency. Since the charge storage capacity can be likened to the charging of the capacitor through a resistor, the efficiency of the charging circuit does not exceed 50%. So, about half consumed by the power Converter will be allocated in the form of heat” on the transistors. So they need more heat sinks.
