SKIING. You can go sailing on skis, not installing them on the mast (see “M-K”, 1982, № 12), but simply holding it in his hands behind him. This sail has a diamond shape, stretched on the d-pad and consists of a headsail and mainsail. Enough to their total area was 5 m2 and was maintained the approximate ratio of 1 : 3.SCREW IN AID
The end of the stick in the hole of the butt is held by the wedge. But eventually, the knot loosened and then the axe is to work not only uncomfortable,but dangerous. If time and opportunity “to peremeschenii” ax no, do at least a simple temporary “ersatz”-mount – tighten a few screws with the so-called Read more…
In the construction of houses large rooms usually equipped with a harness that allows you to turn the lamps (for example, shesterikova) in series two, four and six lamps. At the same time in smaller rooms (bedrooms, children’s) posting are only designed to turn all lamps chandeliers. However, in such rooms sometimes want to include only part of the lamps of them.
1. GENERAL PROVISIONS
In 1946, first flew double an educational-training plane Yak-11, created on the basis of the Yak-3, but with motor air-cooling, ASH-21. Its armament consisted of a synchronous UBS machine gun of 12.7 mm caliber and two 50-kg bombs In 1955 at the request of Czechoslovakia in OKB A. S. Yakovlev developed the under the gun A-12,7. In 1951 appeared the Yak-11 with the nose landing gear and the training Yak-11T with the equipment of a fighter. In Czechoslovakia built a small series of machines under the designation C-11U.
Protection of your house and garden from small rodents, insects relevant today. Various industrial devices “repellents” are on sale, but this same device is able to produce hams with a medium level of training. Unlike many schemes of such devices listed below are quite original. Known schemes are based on the ultrasonic frequency generator (uzch), “loaded” to the piezoelectric capsule. The frequency of these generators can be tailored (adjusted by changing the values of the RC circuit), but it is invariant under the operation of the device, and therefore of the generator. That is, any rodents, insects, birds or animals would not be “programmed” generator uzch (all of these entities are afraid of the discomfort of pulses of a certain frequency), over time, the device ceases to be effective due to rodents or insects exposure.
In 1947 in accordance with the September decision of the government in the aviation experimental design Bureau (OKB-115), headed by A. S. Yakovlev, began development of a heavy landing glider Yak-14 and simultaneously — airborne self-propelled ASU-57. Caterpillar machine was built in the beginning of 1948, and, after a short factory test in April passed on field tests in the research test an armored polygon BT and MV VS (NIIBT Polygon).
