the First German armored vehicle, created in the 1930-ies, was developed by order of the Supreme command of the Reichswehr on the chassis of the car Adler 3Gd. This rather primitive combat vehicle intended to accompany cavalry and intelligence. It had a welded open top hull of the 8-mm armor. Armament consisted of a 7.92 mm MG 13 machine gun mounted in the middle of the body behind the shield and having a limited arc of fire. Carbureted 6-cylinder engine Adler 6S power 60 HP at 3200 Rev/min dispersed heavy (2,1-t) combat vehicle up to a speed of 50 km/h. Armored car had rear wheel drive and steer front wheels, suspension on semi-elliptic leaf springs and hydraulic brakes. The crew of the armored car consisted of two people: the commander and the driver. Radio stations on the car was and the crews maintained communications via signal flags.

Simply by touching the sensing element and actuates an electronic device that includes an alarm or actuator. The sensing element Ан1 — plated plate connected through a resistor R2 with a grid of thyratron MTX-90 (Fig. 1). The potential appearing ka the grid of the thyratron when you touch the plate, sets fire to it. The resulting circuit mtkh-90 pulses through the capacitor C2 is transferred to the SCR Q3 and the load (relay, lamp, siren, etc.). The circuit is powered directly from the mains alternating current. The capacitor C1 plays the role of damping resistor.
I want to share my production version of the arcs security, which set me on a motorcycle “Java” and for more than a year of reliable service. Friends motorcyclists interested in their design: shot size, shape, etc. So I decided to offer them to the readers of the magazine.
Model rotocut of the champion of Russia 2003 G. A. Reshetnikova — further improvement of “sergievskoe” scheme, developed in tstt “Youth” under the leadership of the deserved trainer of Russia L. O. Krasnov. This variant slightly increased the angle “V” pendant of the blades (12°) and has an additional corner of the “V” at the point of kink (folding), which promotes sustainable autorotation.
Executive car AUDI A8 L 6,0 QUATTRO. It is difficult to make a choice between the “Klin” and “Zhigulevskoe” beer; it is even more difficult between firms computers “Macintosh” and “Microsoft”. And it is almost impossible to imagine anyone opting for a luxury car from the four most-most — AUDI A8 L 6,0 QUATTRO, MERCEDES-BENZ S 600 L, BMW760Li and VOLKSWAGEN PHAETON.
Enough next to your telephone to put a small plastic box, as from the speaker there is a loud voice. The secret here is simple: mounted in the box coil (scheme) “detects” the electrical signals of the phone conversation, coming then a three-stage transistor amplifier with low frequency.
Under this title that has become like a calling card, we publish the latest development of the professional engineer and Amateur inventor of the Bicycle (but not only) from the village of Inozemtsevo Galvanoscope district of the Stavropol territory V. M. Gavrilov. This time he invites our readers to design one-wheel trailer — truck.
