For students of the 70-ies – 80-ies there was a special annual period, which was called simply “potato.” All through September and sometimes early October, students performed in the suburbs, working in the fields and harvest the potatoes.
Extraordinary time and an amazing event not only shaped the young student groups, but also allowed to learn from the experience and ingenuity of the rural artisans, that is, without going to the potato field. I want to tell you about one unusual device that made the tractor, teaching students to literally stalk your tractor. Course development and he was the highest.
FIELD KITCHEN… ON THE TRACTOR
Dear editors, in your journal often publishes interesting technical solutions; offer you. Adhesive pen after consuming the content is not just packaging, and the original design for innovation. For example, it can be easily converted into a syringe-dispenser for viscous compounds: epoxide resin, petroleum jelly, grease, grease nitrokey and other materials.
The device to prevent theft in large and small retail outlets, according to many experts, are the most reliable among all types of protection systems applied in practice. Outwardly, they look like two open valves “gate” installed in parallel (photo 1). The device do have a greater probability of determining the anti-Krasnoy label (due to extremely high power pulses supplied to the antenna). However, the pulses of these devices have a negative impact on human health (with frequent and prolonged exposure), mainly due to their high power.
Your dream has come true – and here you are on the sea. Dazzling sunshine, with the quiet rustle of pebbles rolled on the coastal waves, the salty sea breeze caress your hair. Mask, snorkel and fins – your eyes open a wonderful world of underwater Kingdom. You slowly float along the ridge of huge stones and notice the impressive size of the fish. What a shame that you have not taken a vacation speargun. That would be a mining…
Reliable power supply and grounding are paramount to the operation of appliances, computers, local area networks, peripheral devices, connect the various cables (e.g., computer, printer, TV-VCR, and in other cases). The use of protection devices, in particular, uninterruptible power supply (UPS) efficiently only in the presence of good grounding. The practical implementation of a reliable ground as relevant (from the point of view of protection, long-term use and safety) that is no less important than, say, the life and health of a person. Because these concepts are interrelated. How to securely ground the equipment — the theme of my article.
When conducting different kinds of work often have to use hand tool percussion: chisel, punch, jumper and others. To eliminate the negative impact response of the impact on a hard work surface, it seems appropriate to use anti-vibration device (Fig. 1, 2, 3) to which the thread mate replaceable shock elements. The figures shown docked replaceable chisel.
