In this article shows the known constructions of gravitational continuous devices for mixing of bulk materials and the conditional classification of these devices. There is the problem of obtaining mixtures in cases when the volume-weighted amount of one component of the mixture is significantly greater than the second (with the ratio of their mass fractions of 1:10, and more). Typically, in the production for mixtures with a ratio 1:10 are used mixers centrifugal type, which operate in a periodic mode. The problem could be successfully solved using gravitational devices that operate in a continuous mode. The classification represented according to the design of mixers. The levels conventional classification for these mixers: (a) used or no additional mixing elements ; (b) the nature of their physical - mechanical properties.

Keywords: mixer, mixing, construction, mixture, component, bulk material, execution unit for mixing, tray, bunker, gravitation.

The analysis of existing methods of warming up the "old" asphalt with regard to its further use. Found that known methods of heat grinding are energy-intensive, which limits their use in industry. A new method of thermal regeneration based inkjet influence of coolant with subsequent classification of the particles.

In this article is reviewed the nature of organic hybrid nanocomposites. Promising directions in the field of organic hybrid nanocomposite materials will be methods for the synthesis of multicomponent materials, as well as the type of "net net" and "host-guest". The fundamental problem with the chemistry and physics of nanocomposites is dependent "structure-property". Solving this problem will move from research materials to their purposeful design.

Keywords: nanocomposite sol-gel technology, synthesis, nanoparticles.

This paper presents a new neuroimmune-based method for block recognition of railway rolling stock inventory numbers. The advantage of such approach is  classification without using of negative samples. Developed technique combines segmentation and classification that allows to achieve higher noise robustness, segmentation possibility of fuzzy combined digits which have different fonts and typeface, and invariance of existing numbers to scale changes. Proposed method allows to constantly increase the training set for the improvement in classification accuracy by new committee classifiers statistics due to the data reduction property achieved by using the immune clustering mechanism. Research results were implemented in the software system of automatic recognition of cars numbers (ARNV), which is operated on the JSC Russian Railways.
