Not the first time the editors publish original contributions on the improvement of the Bicycle, the author of which is an inventor, engineer Vladimir Gavrilov from the village of Inozemtsevo area of Zheleznovodsk in Stavropol region. With his enthusiasm, he engages in technical creativity and other. An example of this— the second development in this publication, by V. Gavrilov together with his fellow villager M. Losev.
Conceiving the design of the moped, I set a goal to make it easy to operate for the driver any age. This moped I have and get: easy to control on the road and on the dirt road, with adjustable height of driver steering and saddle, stable and powerful at the expense of front-wheel drive with unpretentious D-6 engine. On the latter suffice it to say that it starts as a scooter with a push.
A real scourge of the potato fields was the Colorado potato beetle. And in recent years because of the warm winter it is getting more and more. To deal with it in different ways. But the most reliable and effective way all the same- spraying with special chemicals. If the area is small, then no problem. Buy in store or on the market hand-held sprayer for any model that is charged with a solution of capacity for work! An hour and a half and the plot of the pests exterminated. But this, again, in that case, if the potato plantation is small – five to ten acres.
The compressor unit can be, and is not so necessary equipment in the home workshop craftsman or car enthusiast the garage like a drill or vise. But when such a unit is available, it greatly facilitates certain time-consuming processes (tire inflation, for example), and sometimes significantly improves the quality of work (e.g., painting products with spray). Where work is carried out using air tools because the electric mechanisms (even with low supply voltage) applied in production safety work is strictly prohibited (flammable or explosive), the compressor just needed.
When rented with option to purchase three of the apiary, I realized how difficult it is to handle a large number of bee colonies. Part of the problem was solved with the help of the trough-drinkers, slightly improved development offered by experienced beekeepers in the pages of periodicals. Each of used to me bee-feeders-drinkers consists of a wooden mandrel which is inserted a glass or plastic bottle with thread. Mandrel is better to make from dry birch – less burrs when machining.
Apparently, in the technical work appeared in the phenomenon that can be called bottle-modeling. The fact that modelers in different fields are increasingly used… plastic bottles. From these light and sturdy vessels, they made a great hull models of yachts and catamarans, compressed-air cylinders to drive the action of the compressed air motors air and car. Thin clear plastic was the ideal material for the manufacture of lamps for aircraft models.
At the time of making this simple craft, even the name of which is hard to find: “whether the junk, or boat, or boat, or raft”, I had a “Kazanka” boat is roomy, durable. However, it was intended for sailing with an outboard motor. But what, say, fishing in a quiet backwater after it came a motor boat. To walk on the oars “Kazanka” too heavy and unwieldy. Shipping it to the waters too troublesome to do without the trailer and the assistant was not possible.
Well-known model electric fibroelastic inherent drawbacks: on the table crawl, hands from the constant tension when working with the machine buzzing… to cut delicate items, should be thoroughly accustomed. But if broken flat spring near the nail, there arises a problem of their repair. But the vibrating base, remaining out of work, can be used!
Anyone who self built a house, garage, cottage, etc., knows that the most difficult stage — zero cycle (the Foundation) associated with the preparation of a large number of concrete mix or mortar. Of course, if you have a mixer, then everything is easier and simpler. But to buy such an expensive setup for short-term use is expensive and knead with a shovel in the trough is not very desirable. Way to make the mixer itself. In the “Modeller-designer” there have been several publications on this topic.
History of rocketry in our country today is widely reported in the local media. In my opinion, it is interesting it is stated in the book “Rockets and people” – B. E. Chertok (Publishing house “RTSoft”, 2006) – a direct participant in the whole period of the birth of rocket and space technology. These books “pushed” our children-rocketmodeler to implement the idea: to recreate the models in the basic steps of creating missiles and combat shield of the Fatherland and the achievements in space technology. This project was a contribution of students in the Year of Russian cosmonautics and the 50th anniversary of space flight by Yuri Gagarin.
