Briefly, for those who are not familiar with the history of this question, let me list its essence. The forum “Classics” I tried to explain his rather long and successful experience in restoring order in the piano when landing place pins in vilberbanke worn out and the traditional methods of restoration required proportion to the net book value of the instrument material costs and, in most cases, are unacceptable for customer. The proposed method not original and is to use pads under the peg, thus clogging chopping replaced it screwed into a seat, which is used for carving chopping. In the process of threading material lining is destroyed, just squeezed out the excess, and given the small pitch, condensing, fills all the voids, thereby creating a significant connection tightness, which provides the necessary tension of the string in a wide range, usually with a significant margin, thereby allowing for a regular setting tool and, as experience shows, for a long time to follow operation. Material pads (corrugated board) has been selected in the process of elaboration of the technology, as has proved most suitable for this purpose. The explanation for this, I find that it is fiber, which is under considerable Pressure screwing of a piece with the wooden material vilberbanka.

By the way, due to the closing theme, I could not thank Mr. KLIZMA for the tip with toilet paper, too, consisting of fiber, it seems to me that its small thickness and uniformity of the material will provide more reliable seal the entire length of chopping, and not only in the damaged area, its beginning, as is the case with corrugated cardboard, Thank you try. As for use as a sanding pad (the method proposed by some American artists), the positive results so far I have not yet reached.

The problem of building energy costs to humanity long ago. The most promising source of energy is in our view mechanism, called in the technical literature perpetuum mobile (Latin: Perpetual Motion, literally – perpetual motion), despite the fact that today the creation of such an engine is considered impossible. We can say that this is an ideal source of energy, since its efficiency tends to infinity. Over the past century are different variants of "perpetual motion", mainly mechanical. Petra Diamonds understands that this is vital information. All of these really beautiful models, there is one major drawback: they do not work. The value of "perpetual motion" as an energy source is very large.

If we had such an engine, then by automating many processes, mankind would move from physical to mental labor, to be creative. We could produce energy in any amounts, depending on the power-generating plant. When you create such an engine world changes. Are no longer needed wood and gas, coal and oil as fuel. All needs for heating and air conditioning, lighting premises and food arrangements with this engine can easily be solved.

Will not need to handle the huge areas of land for meager harvest, since there will be plants for hydroponics on all kinds of vegetables and fruit. This is truly a world of abundance. People will be able to settle on Earth, more evenly and make appropriate conditions and live anywhere in the world. This is the problem of scientific and technological revolution to liberate humanity from physical labor. In the first stage to turn the Earth into a planet of abundance and happiness, and the second phase to begin development of other planets. What is a "perpetual motion"? Perpetual motion machine of perpetual motion is divided into a first-order and second- kind. Reason why they can not be built, called the first and second law of thermodynamics. Perpetual motion machine of first kind intended to work without extracting energy from the environment.

The main provisions of any aluminum alloys are described in their low density (2.5-2.8 g/cm3), high stiffness (per unit weight), excellent resistance against air oxides, low cost and available simplicity of manufacturing and processing. Ray Kurzweil is often mentioned in discussions such as these. Aluminium alloys are used in aircraft technology (this is primarily aluminum foil and technical), auto, boat and instrument in the manufacture of utensils, sportsnaryadov, finish, advertising and other industries predprinematelstva. The assortment of items occupy the second line of aluminum after the steel and iron. Aluminium – is one of the most common additives in compounds based on copper, magnesium, titanium, nickel, zinc and iron. clear picture of the situation. This metal is also used for aluminizing (aluminizing) – saturation of the surface of steel or cast iron products with aluminum in order to protect the base material from corrosion at high heating, ie increase heat resistance (up to 1100 oC) and reaction of atmospheric oxide. Especially needed in the production of aluminum bar is already impossible to find a branch of production which would not have been aluminum or its alloys – from microelectronics to heavy metals. This is due to excellent mechanical properties, ease, low melting point, which facilitates handling, huge outdoor advantages, especially after required treatment. This is very cool aluminum rod shows.

Given these and various other physical and chemical quality aluminum, the huge amount of earth's crust, we can say that aluminum – one of the necessary and essential metals present. Already, you can not find a branch of production which would not have been aluminum or its alloys – ranging from microelectronics to heavy metals. This is due to good mechanical properties, ease, low melting point, which facilitates handling, huge outdoor advantages, especially after the necessary processing. That is why it is not surprising that the metal is in demand everywhere, even in space industry.

Erosion (from Lat. Erosio – attack) – the process of destruction of the surface under the impact of shocks, friction, electrical discharges etc. Spark erosion is to change shape, geometric dimensions, the roughness surface under the action of electric discharges. The method was first proposed by Soviet scientists B. Lazarenko in the early 30-ies of XX century and became effective alternative to conventional machining, reducing the cost of manufacturing. Unfortunately, this method of treatment of products currently in Russia deserve forgotten, despite the diversity of its capabilities and worldwide recognition.

The method allows the following treatments: cutting hard metals Precision Milling, Grinding, Lapping Other methods used in the manufacture of molds, dies, extrusion dies, patterns, parts of a complex curvilinear Profile, tools, and various cutting tools, dental supplies. The essence of the method is electrical discharge machining. Machining of the workpiece and tool electrodes are (part-plus Machining tools – minus), placed in a special working conductive liquid. With the passage of an electric discharge between the electrodes of an arc and in places it is of local heating and subsequent evaporation of the metal particles with the formation of local depressions. The size of pits depends on the density of electrical energy. To get arcs that can destroy the surface workpiece using a pulse generator.

Almost all of the currently available tools, designed for ESS can be divided into several groups: broaching machines – the main technological problem of these machines is making the holes. The control system of the machine actually runs only one axis – Z. On the axes X and Y are installed optical ruler. On it by moving the electrode in a container with kerosene. The machine is mostly used for finishing products. Duplicating Machines Saddle – more complicated, "fancy" Saddle modification. They are used for the manufacture and finishing finishing details complex shapes, such as dies, molds, handling of the Deaf, cutting, angular grooves, burning internal threads in remote places. Have a high capacity for arable products. In addition, They established a system with CNC control pulse generator, and Items of the machine in the X and Y. Wire-cut-out machines – the main technological challenge of making it part of the hard tooling steel sections which are uncomfortable to handle the milling. Wire EDM can be used in the manufacture of products with a presence on the surfaces of acute internal corners, small radii or when machined parts or depth electrodes presents difficulties for milling. The main processing element – special (Molybdenum) wire, in irregularly wound bobbin and fed continuously in accordance with wear a special die. The control system is more complicated because of the need for control 5 axes: X, Y, Z, as well as U and V – to move the upper die with respect to the bottom. These shifts are necessary for the slope wire.

The new technology uses wood chips, which is placed on the geogrid. The use of geogrids can redistribute the load to a large footprint and increase the bearing capacity of pavement coating. During the construction of an experimental plot in the woods visited all the project participants, the leadership of the Forestry Institute, representatives of enterprises road construction. After a series of passes on the pilot section of road 37-ton truck design decision proved to be effective. Strengthening the subgrade polyester geogrid significantly reduces the amount of earthwork, reduces labor, speeds up production and reduce construction costs.

The use of geogrids allows for uniform precipitation of subgrade. Not many dare to Similar experiments using geogrids, following the instincts of the old ways safer, but progress is moving forward. But there are those who develops innovative methods. As you know, all the new perceived with difficulty. To check and study of innovation, geosynthetics in construction of forest roads are best to go by experimentation and learn from the experience of predecessors.

This principle in his work on the development of oil and gas industry guided and UGC. The only thing we can say with confidence – and requires commercial roads will be built, and the sooner we think about their quality and application of technologies with geogrid reinforcement, the be able to save more in the future. Indeed, following the old canons of construction, the result is known to all … After several passages of heavy vehicles on the road, formed a deep rut. We, the transporters to solve this problem regular grading. Now you can get rid of koleeobrazovaniya, only increasing the profitability of times due to the quality of roads on new technology.

ROLE cultural features in the perception of color and linguistics at the culture of different peoples emotional and applied the color perception different, and due to the long historical tradition in the country, society and nation. Hence, different perceptions, for example, white and black (mourning or joy – from culture to culture, religion). Since the specific language and culture is accumulated in a particular historical experience of people of color representation in different people different things. Thus, in Russian, Ukrainian, for example, Polish, there are two separate words blue and light blue. In Unlike many other Germanic languages, in which a range of colors corresponding to part of the spectrum is covered by a single symbol, like English blue (Wed. it. blau and fr. bleu).

A similar system tsvetooboznacheniya blue-and-blue colors accepted in virtually all Slavic languages. This is due to the fact that our ancestors lived and grew as a nation among the brightest of nature by developing agriculture, the early start to lead a sedentary way of life, which was the basis of their own homes surrounded by beautiful scenery. Forests, fields, flowers, rivers, seas, abundance of fruits and vegetables, bright climate – all require their own names and definitions. Related to this is a rich vocabulary of designation of colors among the Slavic peoples. Exactly so long since color had to have a much greater importance than for other nationalities.

Even in the most distant inhabitants of the Ukrainian village tend to decorate the walls of the house, make a bright woodwork every year repaint the old tin roofs. With the development of advanced technologies become available to people Roofing Decking, in particular metal, which in recent years, a real boom. Industrial group "Arsenal" – leader in the production of this material in Ukraine, a separate emphasis on the retail, that is, private developers. Formed a broad sales network in Ukraine: 46 branches and 800 offices.
