IMPROVING THE PHOTOELECTRON SEPARATOR WHEN SEPARATING SUNFLOWER SEEDS
DescriptionTraditional processing technology of piles of sunflower seeds in agriculture requires consecutive through the whole set seed-cleaning machines installed in seed-cleaning complex or aggregate, for each stage of which are organic impurity, broken seeds, shriveled and milled seeds. The seeds of the main culture are subjected to long-time effects of the working bodies, leading to their injury and the necessity of manning the production line machines the same performance that is not rational. One of the ways to enhance the process of separating the seed material in seed-cleaning complex is its fractionation by applying photoelectron separator at the final stage of seed treatment. Qualitative performance of photoelectron separator on fractional technology showed that the purity of the seeds varied from 99.80 up to 99.98% depending on their size Ø7–Ø8 mm Ø8–Ø9 mm, respectively. The content of seeds of the main culture in the waste ranged from 65.60 % (fraction Ø7–Ø8 mm) to 68.83 % (fraction Ø8–Ø9мм). The weight of 1000 seeds ranged from 117 g (fraction Ø7–Ø8 mm) to 146 g (fraction Ø8–Ø9мм). Seeds obtained in fractions and existing technology (without fractionation) meet the requirements of GOST. The output of treated seeds in the fractionation varied from 93.20 % (fraction Ø7–Ø8 mm) to 92,90 % (fraction Ø8–Ø9 mm). Comparative tests of photoelectron separator F 5.1 in seed-cleaning complex by the division of sunflower seeds on the existing and fraction technology showed that in the photoelectron separator it is necessary to use fractional technology. So, as it allows reducing the content in waste of seeds of the main culture and increase the qualities of seeds depending on their size fractions

A SURFACE RUNOFF CLEANING PLANT FOR THE TERRITORY OF THE NOVOROSSIYSK SEA PORT
DescriptionThe article considers scheme of sewage treatment plants AG-STOK of Novorossiysk trading sea port, designed to clean the surface runoff from the territory of industrial sites and residential areas to the norms of discharge in the drainage network. The installation includes a well-separator, a storage tank, mechanical cleaning of solids on a mechanical filter, filtration through a filter with granular loading and filtration through a filter with sorption loading. The treated runoff, which corresponds to the conditions of discharge into the urban drainage network, accumulates in a tank of clean water and is diverted to the storm sewer network. There are: the scheme of treatment facilities, the explication of equipment, a photo of a mechanical filter, a filter with a granular load and a filter with a sorption load. The indicators of surface runoff correspond to the norms of the maximum permissible discharge

Description
In this paper, we investigate the stability dependence of integrated information content on the distance from the celestial bodies of the Solar System, with the change in the extensive pre-cases as the total number of cases, the implementation of the choice of social categories, and the number of categories. It was found that for each celestial body, there is a set of categories in which the depend-dependence of the integrated information content of the distance is determined with the greatest certainty. A model of the gravitational sensitivity, based on the mechanism of hormonal regulation of heat and pressure is discussed.

THE DEVICE FOR STORING AGRICULTURAL MACHINERY IN PROTECTED FORM IN OUTDOOR AREAS
DescriptionThe carried out analysis studies the influence of various factors on the preservation of agricultural products and shows that it is largely determined by design features of machinery and technological methods of use. The efficiency of agricultural and mobile trailer machines has been forming by service and storage. Low quality of work associated with the storage of agricultural machines is conditioned by the fact that the lack of financial capacity of rural producers on acquisitions of modern equipment and materials for carrying out the preparation of for long storage, and also the construction of modern agricultural machinery storage sites. If a car can be fully or partially protected from the solar radiation, rain and snow, simply by removing it in the room, under a canopy or covered with a protective cover, by the formation of condensation on the surface of the machine units and parts these ways to protect do not work. Enhancing of preservation of agricultural machinery is possible when protecting the vehicles from atmospheric precipitation in the form of snow and rain, influence of solar radiation, and also due to the change heat exchange processes of the machine with the environment that prevents the formation of moisture condensate on its surface, ie. we have to create conditions when cooling rate at which the surface of the machine would be equal to or less the rate of cooling air. This is possible through the use of a special design, which would prevent the intense heat radiation of the machine into the environment, ie, would reflect heat rays using its surface and return them to its surface and thus fulfill the role of the heat shield
