A model system was designed and test trials of physical and mechanical characteristics of small – crystalline and granular flotation potassium chloride are studied. This model system allows to design storage and transportation of fertilizers in bulk in railway wagons and it has the same static and vibrational load as real system. The effect of temperature and relative humidity of the air on hygroscopy of small – crystalline and granular КСl were studied. Furthermore the influence of static load, and time length of compression process of fertilizing layer and parameters of static and vibrational load on composition of КСl granules were investigated. It was experimentally proved that the humidity increase (0,5 %) of granular КСl and the increase of static load and time length of compression process of product during transportation in bulk lead to increase of compaction degree and caking ability of product. Research of the influence of high static load (10-30 kg/sm2) and time length of compression process of fertilizing layer on caking ability and degree of compaction show that small – grained KCl has smaller degree of compaction and considerably higher value of caking ability in comparison with granular KCl.

Ingenuity in the new science is different from the inventive technique that invented intangible tools of knowledge - concepts, principles, laws. Modern inventor of new technology, wanting to maximize their arsenal, serious scientific knowledge, without which the inventors treated wheels, the steam engine and mousetraps .In this regard, the development of the Russian innovation system needs a dramatic increase in research universities. The article deals with examples of scientific discoveries that demonstrate that the knowledge economy promising raw material economy. And in first place in the priorities therefore goes high quality engineering education. In Russia almost no programs for innovative engineering, a course which has been developed by Israeli scientists Clement Levkova and Oleg Figovsky. While it is realized only by the Open University Skolkovo. In particular, this course shows that the development of innovative products is the preparation and implementation of innovative changes and consists of interconnected phases forming a unified whole. The innovation process involves the creation, development and dissemination of innovations. It is a common goal of a certain subject innovation economy. This activity is aimed at implementing the completed research and engineering applications in the form of new or significantly improved and marketable product. Results of innovation are new or modified processes used in practice, as well as associated with these changes, additional research and development. Innovative engineering is based on the systematic, focused and coordinated interaction of all participants in the innovation process at the executive level. However, the implementation of the innovation life cycle stages of technical innovation central figure is an innovative engineer. Innovative engineer carried out the task of building a functional model (structural and functional image) future innovation and its prototype. Without the introduction of this course is difficult to expect a breakthrough in the Russian engineering education.

This paper presented the study of the mechanochemical activation powder mix in dry and liquid grinding media, accompanied by agglomeration of the particles. It Is shown that when agglomerate particles having a bimodal size distribution is forming during the treatment in a dry grinding media and partially (2 wt % ) decaying at grinding by pestle in mortar. The transition to liquid grinding media is leading to a unimodal size distribution and increasing dispersion of the agglomerated particles, characterized by secondary agglomerating when using the alcohol and destruction when using activation in saturated aqueous solution of boric acid. Inherited effect mechanical activation parameters on the compaction process during cold compaction and hot stamping has been determined. Application treated in a high energy mill in an grinding media saturated aqueous H3BO3 Al-Si powder mix results in the formation of moldings with low cold-pressing relative density (0.735) and the activation of the hot stamping compaction (|εh| = 0,592) providing production of hot-deformed powder material with increased mechanical properties.

A model is presented for the calculation of thermoelastic stress and displacement in semiconductor structures
due to laser processing. Developed software based on the model allows to determine the optimal parameters of laser processing with taking into account the physical and topological parameters of the structure. The model is divided into two tasks: the non-stationary heat conduction equation is solved, and the equilibrium equations and Hooke's law. For equations solution was used the finite difference method.
