The development of technical devices in almost all industries is aimed at creating universal devices that allow performing several operations. The forest industry is no exception. The creation of a taxation tool that provides the ability to perform several measuring operations, which is the goal of the work, will increase the efficiency of the taxator while reducing the physical load on him due to the need to have fewer measuring instruments with him. All this indicates the relevance of this work. To achieve this goal, a number of tasks were solved in the course of the work, the main of which were: analysis of known designs of taxation instruments, synthesis of new technical solutions for their unification, patenting of a new technical solution. The use of system analysis made it possible to achieve the set goal, to propose a new patentable solution for a taxation device that combines the functions of an altimeter and a full gauge. The approach described in the paper to the creation of new designs of universal taxation devices can be used in teaching engineering creativity to students.

the article shows that recycling is being paid more and more attention in Russia and abroad, as the important factor of resource saving and solutions of ecological problem. It’s mentioned that despite the realized research and certain implementation experience, a lot of problems is still not solved. Special attention’s drawn to the acuteness of the problem of production and consumption waste recycling, the search and implementation of new sci-tech, business and also legislative solutions in this field
