PROPERTIES OF FOREST SEED SAMARA, WITHOUT PTERYGOID APPENDAGES, LEGUMES AND WITHOUT PERICARP
DescriptionProperties of forest seeds are the basic and initial data for substantiate technology and technical means constructions, to separate the seeds from the samaras and extraction them from the legumes, and also to substantiate constructive, technological parameters and operating modes of seed-cleaning machines. So far, there are not enough full information about the technological and mechanical properties of forest seeds, this makes it difficult substantiation and developing new technologies and technical means, in particular, to separate the seeds from samaras hardwoods and extracting legumes from the leguminous trees. The article presents the results of studies of technological and mechanical properties of forest seeds with samara and without pterygoid appendages: Norway maple, ash and elm ordinary, as well as legumes: honey locust, white acacia, acacia yellow and pure seed. Were studied: weight of 1000 seeds, volume weight, mass and volume coefficients, angle of repose, the coefficient of static friction and the coefficient of dynamic friction of the various working surfaces, holding strength samaras to forest seeds and strength of legumes pods. The data obtained are used for substantiate technology and technical means constructions, to separate the seeds from the samaras and extraction them from the pericarp

IMPROVING THE RAFT DESIGN FOR THE ALLOY OF TIMBER DOWN THE RIVERS WITH SMALL DEPTHS
DescriptionWe describe the construction of the raft, formed of flat raft sections; it is shown, that the given raft has deeper draft, which increases during the voyage. The construc-tion of the raft, formed from flat raft sections of stabi-lized buoyancy is presented. The proposed raft has less draft, the intensity of increase of which is not signifi-cant when navigating; it allows it to go through the sec-tions of rivers with smaller depths. A description of raft formation is given

IMPROVED OF BEARING EQUIPMENT IN FOREST PROCESSING
DescriptionIn this article, application of perspective polymeric metal anti-frictional material in the knots of a friction in that case when the plug rotates with shaft to the motionless base of the bearing is considered

IMPROVEMENT OF THE CALCULATION OF THE PROFILE VOLUME OF EARTHWORKS IN COMPUTER-AIDED DESIGN SYSTEM
DescriptionDependences for calculating the volume of earthworks profiled in computer-aided design system (CAD) are presented, taking into account the change in the parameters of the transverse profile of the subgrade of the road, the slope of the hillside. These function are used in computer-program of calculating the volume of earthworks profile, which allows us to calculate both the volume of earthworks profiled on the projected area of the road, and the amount of work on the mounds and excavations on the specific pickets, which allows to differentially estimate the distribution of ground masses for the development of technological processes of construction of subgrade, and it is also a source of information for the design of reserves and stockpiles of soil in CAD

Description
The results of studying the ordinary pine condition in geographical cultures of the Central forest-steppe are cited in the article. The general pattern of the ordinary pine intraspecific variability is represented. The data of origin influence on safety, efficiency, qualitative adjectives is presented. The pattern of ecotypes adaptability to new environment conditions is presented
