With the development of industry and science, the size of the patent base is growing, as well as the number of patent applications received by the agencies regulating the issue of patents is growing. Each patent application must be checked for the uniqueness of the patented technology, for this, the patent office experts need to search the patent database and find analog patents. In the absence of analog patents, this technology can be considered unique and accepted for patenting. Since the patent database of various departments can number tens of millions of patents, such a patent search and evaluation of the uniqueness of the patented technology can take a very long time. The existing systems do not meet all the requirements and do not have the full necessary functionality. This article describes the development of an automated system for searching for analog patents in the patent array.

The purpose of this study is to perform a classification to form a knowledge base in the field of harvesting and use in industry and in the social sphere of one of the valuable types of non-wood forest resources-tree greens. Such knowledge base is necessary for synthesis of new progressive processes, machines and mechanisms for harvesting and use of wood greens. The basis of the classification formation is based on the analysis of technological and technical solutions based on scientific and technical search, given in inventions and utility models patented in 2010-2019 in the Russian Federation. As a result of researches the main directions of patenting of developments in the field of preparation and use of wood greens are classified.

The questions of mathematical interpretation of results of trajectory measurements are discussed in terms of increasing the accuracy of identification of bearings of unmanned aerial vehicles during their movement in a "swarm" - a group. Variants of identification of horizontal and spatial bearings are offered. For each of the variants, criteria are proposed for identifying the belonging of the measured values to the same object in the group and the conditions for achieving them. The situation of false positives is shown. It is determined that additional identification measures are needed to eliminate false bearing triads and uncovered ambiguities, including the use of combinatorial exhaustive search algorithms. For their study, it is necessary to develop an experimental statistical model with an algorithmic description of cause-effect relationships, which is a further development of this work.

With the safety position and the environmental and economic feasibility of perspectivity renunciation of the use of imported liquefied chlorine (substance of 2 hazard class) and replacing it with an electrolytic solution of sodium hypochlorite (4 hazard class), produced by on-site consumption. Hydrogen, which is a waste product , is thus partially (15-20%) to reduce the need Rostov TEP-2 in this matter and to provide a corresponding reduction in energy and economic costs.
