The technique of the geometrical analysis and the analysis of force loading of combined drills with the replaceable multiface plates is offered in this work. This technique is allowing to determine geometrical parameters and specific force loadings in each point of a plate’s cutting edge taking into account its orientation in the drill case. Application of this technique allowed to establish the reasons of the drill’s low durability. The offered technique allows to design drills from the minimum unbalanced radial component of cutting force which increases its working capacity and the processed holes quality. New designs of combined drills both with two, and with three replaceable multiface plates are offered in this work. The durability of this new drills is increased by the plates mutual turn for the minimization of an unbalanced radial component of cutting force

In article gasdynamic approach for the solution of a task on heat distribution in simple gas pipelines on the basis of consideration of a current of gas in a laminar mode is considered. The objective is solved by means of research of system of the equations of work of extending gas taking into account an assessment of difference of temperatures at explosive decomposition of a working product. Classical approaches to research of distribution of heat in a simple cylindrical pipe are thus taken as a basis the main dependences characterizing both full, and the current work of a working product by means of correction coefficients and a ratio of temperatures of heating of walls Are presented. Connection between pressure is established at different weight ratios of gas.

"This review covers various methods of synthesis LaMnO3 ferroics. The general analysis of the solid-phase synthesis reactions methods and wet methods (sol-gel, sorption, co-precipitation) are carred out. The original results of LaMnO3 syntheses from various precursors by means of the in situ method are showned. The advantages and disadvantages of different methods of synthesis are determined. The analysis of synthesis LaMnO3 ferroics published data is shown:
- the structure formation of LaMnO3 in perovskite-type phases occurs at different temperatures, depending on precursors states;
- LaMnO3 perovskite phases differ in symmetry and unit cells parameters at room temperature, depending on the preparation conditions;
- the highest synthesis temperature of LaMnO3 are typical for solid phase reactions method (950-1050 ° C), the lowest - for wet synthesis methods (500-700 ° C);
 - the synthesis conditions effect the stoichiometry of LaMnO3 for oxygen content.
Our studies of structure formation processes of LaMnO3 by in situ method are allowed to define the role of precursors states at synthesis of solid phase reactions methods, adsorption, co-precipitation and sol-gel mixtures.
It is determined that in samples prepared by wet chemical methods, the formation processes of  LaMnO3 perovskite phases occur at lower temperatures than by solid phase reaction (sol-gel precursor - 500 <T <600 ° C; precursors obtained by coprecipitation and sorption methods - at 600 <T <700 ° C and 700 <T <800 ° C, respectively).
