Party NTTM, army innovator Y. Bandurko, suggested a simple device for cutting steel wire rope. Steel is the base plate to which are welded crosswise arranged vertical edge guides. Between them with the edge of the knife upwards to fit the bar, he lowered the rope, and the top plate is inserted into the mandrel. Then all of this fixture Assembly is installed under the press, the mandrel takes its stress on itself and presses on the rope, cutting it on the blade of the knife block.

It would seem that not so long ago appeared in our kitchens “blue light” — the first of the Saratov gas. The enthusiasm that accompanied the displacement of them wood-burning stoves, kerosene stoves and kerosene stoves, over time, subsided. Gas was not an ideal fuel for stoves. The allocation during the combustion of harmful substances, the constant danger — and suddenly blow out the flames the wind and the room is filled with explosive mixture, — all this has led to the fact that gas stoves were gradually superseded by electric. The advantages of the latter compensate for even that heat the burner costs a bit more expensive.
To debug transistor-based hardware is much easier if you have the regular store stable voltages. Two adjacent shoulders of the bridge rectifier V1, V2 connect the unit Zener diodes V3 — V8 and V9—V14, V15 — V20, V21 —V26 or V27 — V32 (Fig. 1) exercising, in addition to rectifying the current, stabilization of the output voltage 7, 8, 9, 10, 12, 14, 16, 18, 20 or 24 V at a current of 30 mA. When the input voltage is within 110 — 240V output changes by 0.2 V and the current is 1 mA.
To create a device is simple, inexpensive to perform and at the same time with high performance — such is the aim of gliders. We offer our readers the description is very promising glider “Albatros” open class, created by Moscow engineer A. Z. by rabanim in early 1978. This device has been widely tested and has a high aerodynamic qualities. From other phones open class “Albatross” stands simple design (all tube frame straight), in combination with precise profiling of the dome, which provides pre-curved armor combined type (front — hard, back — elastic). The frame of the Albatross allows you to apply domes of different shapes and size without any alterations and additional adjustments.
The Renault Logan sedan of the company “Avtoframos”. If in your childhood you received a gift of a real soccer ball or, say, skibord, you will probably understand my feelings when I suddenly found myself the owner of a Renault Logan—car French origin, and in the Moscow production.
Remember, what is the simplest electrical circuit? The galvanic battery and light bulb connected by conductors through the switch (see the article “Ohm’s law” in the “M-K” N2 9, 1978). If such a circuit connection line length of about 30 cm to bring a compass, its magnetic needle will tend to become perpendicular to the conductor (Fig. 1).
During archaeological excavations of ancient burial mounds and graves along with different kinds of jewelry in many meet the beautiful decorations, made of copper. Try your hand in the manufacture of such jewellery available to everyone — you just use a copper wire and a simple improvised devices, prompted by the Hungarian magazine “Earmaster”.
