Description
In this article we consider the general problem of integration with external billing system software complexes and analyze the main methods of the solution of the problem on the example of a specific task. We also carried out the comparative analysis of the traditional methods and came to the need of modifying the best of them. The mathematical model of the method is given, and the detailed description of the architecture of intelligent gateway is shown. To demonstrate the effectiveness of the solution it is proposed to do a comparative analysis of system’s performance and alternative variants. At last, the conclusion of the wider applicability of the developed system, as well as the potential modifications of it, is made

Description
The article investigates the possible pathways for the formation of crotonaldehyde in wine production in the result of the activity of wine yeast and lactic acid bacteria. It established that exposure to exhaust gases, noble rot, pathogens and pests on grape plant does not lead to the biosynthesis of crotonaldehyde in grape berry. The experimental data to identify probable pathways for the formation of crotonaldehyde during vinification has been presented. The effect of the test substance on the life of yeasts and lactic acid bacteria has been estimated

TECHNOLOGICAL SETUP OF A HOPPER FEEDER FOR PIGS
DescriptionConstructive-technological parameters of a hopper feeder have been established. They help to synchronize feeder’s flow and feed consumption by animals. Synchronization of these factors eliminates the initial cause of feed loss during fattening. It was found out that the main influence on feed loss is exerted by shape and geometrical parameters of feedstuff fill at the bottom of feeder, which depend on their physical and mechanical properties and on the feedstuff level in a hopper feeder. The fill balance condition at the bottom of a feeder is provided by compensation of feedstuff weight pressure inside a hopper due to the weight of a surcharge layer. The thickness of layer is proportional to the height of feedstuff volume inside a hopper and does not depend on technological gap between discharging feed line and the bottom of a feeder. It is found out that the discharging feedstuff is distributed throughout the bottom of a feeder. There is a central nonmoving area in the cone shape in alignment with the axis of the discharging feed line. This area functions as a shutter, which reduces the effective area of discharging channel. It is determined that the flow of feedstuff is set by adjusting the technological gap between discharging feed line and its bottom within defined limits. In accordance with physical and mechanical properties of feed this dependence of feedstuff flow allows to determine corresponding functional parameters of discharging feed line in order to meet the needs of a group of fattening animals

Description
The article presents a study of parameters and modes of operation of machines for soil cultivation. In determining the parameters and modes of operation of machinery for tillage we have applied the theory of similarity and dimensions of physical quantities. We have obtained the regularities of disclosing the relationship of the parameters from the medium to the energy characteristics of the process. As the initial data we used test protocols of machines for soil cultivation (Central - Black Earth, Kubanskaya, Sibirskaya, of North - Caucasion MIS, RosNIITiM) : KPI - 3.8, AРC - 3.9, AKV - 4, AKM - 6 - V, AMP - 4 APC - 4 A, AРC - 10 APR - 4.4, APU - 6.5 APSH - 6 , CNC - 6.0, CSТ - 3.8, APC - 4. We defined the formula оf dimension parameters and modes of operation of machines for soil cultivation and properties of soil (traction resistance, depth, width, speed, hardness of the soil, acceleration). Based on dimension theory we have received similarity criteria. Based on the correlation analysis and the least squares method we determined the nature of addiction and the coefficients for it. We have also received a graph for determining the operating modes and parameters of machines for soil cultivation

PYROlYSIS RUBBER WASTE REPROCESSING FACILITY WITH MINIMAL ENVIRONMENT IMPACT
DescriptionTo solve the problem of reprocessing and use of rubber waste in Russia it is necessary to develop and adopt a set of measures regulating the procedure for their accounting, collection, storage and delivery for processing, as well as preparation and promotion of legislative acts at federal and regional levels, stimulating an increase in complete renovation and recycling of used tires. Russia has seen a steady increase in quantity of waste; fundamental changes to this trend in the nearest future are not expected. This is obviously due to the growth of industrial production and the level of final consumption. In this case, wastes of consumption will grow faster than production waste due to advanced growth of products of final consumption - primarily household, computer and electronic equipment, household items, clothes, cars, etc. [2]. There are several methods of used tires and rubber waste reprocessing in general, but we focus only on the pyrolysis process, as one of the most efficient and environmentally friendly. Pyrolysis is thermal decomposition of many organic and inorganic compounds. In a narrow sense, the natural decomposition of organic compounds with air deficiency. In a wider sense - decomposition of molecular entities constituting less heavy molecules or elements under the action of raising the temperature
