Fluorescent light (LDS) are widely used today in various industries and in everyday life. Unfortunately, the durability of LDS is extremely low. Their weak spot — helix required for the ignition of the phosphor inside the lamp at the time of inclusion. Two of them — from both ends of the lamp, and if even one of them burn out, to include LDS with the standard circuit (containing inductor, capacitor and starter) is impossible. In such a situation it is necessary to change the blown bulb with a new one. Therefore, where there are a large number of lamps (for example, in manufacturing plants, apartment buildings, stairwells and other similar cases), during the years of operation goes down and accumulates a lot of LDS with blown spirals.LDS-THE STATUE

River passenger ships — a very numerous class of vessels. Small flights of ships to last several hours. Passengers are protected from the weather and can relax in the soft comfortable chair. Large vessels are often built specifically for multi-day journeys and equipped with comfortable sleeping cabins. Small have a small draught and a displacement of up to 80 tonnes, that allows to operate them even in the rivers. A model of such “microlayer” is very beautiful and has good driving characteristics.
The French fleet of the late 80-ies of the XIX century, is familiar to specialists first of all thanks to Admiral Théophile OBU and his “young school.” Well known for their ideas of building naval forces: a Horde of destroyers, spread across ports and backed by armored coastal defense vessels.
In rural homesteads, and in ordinary suburban houses, which in mother Russia today Nemer-unread, without any stove — Russian, Dutch or a simple “stove” — is hardly a cost, even if “we have gas in the apartment”. Only still far not everywhere and not all have the “blue fuel”. But even if the gas is supplied, in the heat of summer to stand at the stove in the kitchen and prepare food — a handful. But have to do it, as you know, not once a day.
At competitions of the Moscow schoolchildren model pupil of the 55th school Igor Svistunov in adverse weather conditions (wind of 6-10 m / s) scored 501 points. Only breaking model at the start of one of the tours did not allow Igor to achieve absolute victory outcome in all five rounds.
No, it will, of course, is not about the equipment of the dental office on a production site. However… picture this: a dentist, firmly gripping with two hands the body of the machine with the motor inside, trying to get to the tooth of the patient a thin boron fixed in the Chuck mounted directly on the motor shaft. Inconceivable, right! Everyone knows that the engine and boron spaced and connected to a long flexible shaft: hand of the doctor easy and comfortable to hold thin tip of the working head.
