Abstract: FIELD: plastic working of metals, possibly cutting sheet, shaped and rod materials. 
     SUBSTANCE: combination type shears include hydraulic cylinder with control unit; two levers having cutters with cutting edges and mounted with possibility of rotation one towards other in common axle. Cutting edges have cutting teeth. Fixing teeth are formed on outer surface of lever ends. Length of cutting edges consists at least of 0.6 of level length. Cutting edges are tapered one to other by angle 40 - 50° relative to cutting line. Cutting teeth have pitch Z = 5 - 8 mm, thickness l1 = (0.2 - 0.25)Z, height h = (0.25 - 035)Z and width of initial land l = 0.8 -1.0 mm. Each tooth is tapered by angle α = 60 - 80° to side of lever rotation axis and it is sharpened by angle β = 25 - 35°. Fixing teeth have pitch 3 - 5 mm, depth 1.0 - 3.0 mm and inclination angle 60 - 80° to side of lever rotation axis. In variant levers end portions are tapered on their outer surface along length of 4 - 10 teeth by angle α 1  = 20 - 40°. On inner surface of levers before cutting teeth smooth supporting surface with width 20 - 40 mm is formed. 
     EFFECT: enhanced efficiency of cutting and drawing apart due to using optimal non-symmetrical configuration of cutting and drawing apart fixing teeth.

Abstract: FIELD: power supply for electric switch and its relevant power system. 
     SUBSTANCE: proposed electric switch 1 is inserted in current line 1 between AC supply E, better AC supply mains, and load L to interrupt power supply or to energize load. Switch is also connected to primary circuit W1 of transformer 3. Power required for switch control unit and probably for switch proper is taken off bypassing switch when it is in ON-position a and from transformer secondary circuit W2 through rectifier 4 when switch is in OFF-position during power supply to load L. Novelty is that transformer 3 is designed to function so that it saturates during every half-cycle of supply mains current and secondary-voltage saturation peaks (KP) of transformer secondary circuit W2, W2a, W2b are rectified to produce DC power when switch 1 is in OFF-position k. 
     EFFECT: reduced size.

Abstract: FIELD: textile, paper. ^ SUBSTANCE: invention is designed for using in the wood-pulp and paper industry. It suggests a method of thermomechanical refinement of wood chips and a unit for this operation. The wood chips are prepared for refinement by holding them in steam to get them soft which is followed by crushing and dehydration of the softened wood chips with compression to reach concentration of the hard matter more than 55% and dilution of the crushed wood chips to reach concentration within the range of about 30-55%. Crushing is accompanied by a partial separation of the material fibres. The diluted material is suplied to the primary refiner with rotating disks whose each of the opposite disks has a pattern of knives and grooves of the internal ring and a pattern of knives and grooves of the peripheral ring. The wood chips crushed and partially separated in fibres are completely separated in fibres in the internal ring and the fibres received are fibrillated in the peripheral ring. Crushing along with compressing, dehydration and dilution are performed at one intergrated unit located immediately above in the course of the production line from the primary refiner and the further fibre separation and fibrillation are performed only between one set of disks in the primary refiner rotating relative to each other. ^ EFFECT: simplified manufacture of high quality thermomechanical wood pulp and reduced energy consumption. ^ 43 cl, 28 dwg, 14 tbl

Abstract: FIELD: crude water treatment. 
     SUBSTANCE: invention, in particular, relates to water-oil emulsion demulsifiers for treatment of crude oil before refining. Method of enhancing efficiency of commercial forms of demulsifiers is implemented by preparing said commercial forms using binary solvent consisting of a hydrocarbon and an alcohol soluble therein. Optimal concentration of alcohol and active part of a reagent in the solvent ensure formation in crude oil of critical emulsion with coacervate phase of high-molecular weight compounds contained in demulsifier. Optimal composition of solvent and presence of active part in the commercial form of given reagent corresponds with maximum optical density of that commercial form in hexane. In this case, demulsification efficiency is enhanced owing to extraction of naturally occurring emulsifiers contained in crude oil by coacervate phase of demulsifier. 
     EFFECT: enhanced demulsification capacity of commercial forms of demulsifiers due to transfer thereof in hydrocarbon into state of critical emulsion.

Abstract: FIELD: physics, radio. 
     SUBSTANCE: invention is related to the field of radio engineering, in particular, to methods for generation of sets of orthogonal pseudorandom code sequences used in radiolocating, radio navigation and communication systems, which use pseudorandom phase-manipulated signals and code division of access channels. During formation of pseudorandom sequences (PRS) set, initial PRS that consists of N prs  symbols is once recorded into entry register of recurrent generator, at that in order to generate periodic exit PRS, interlacing of initial PRS symbols is carried out cyclically by N max  clock pulses in every cycle in compliance with law of fractal reflection with chaotic dynamics. For this purpose at every i clock pulse of interlacing, n i  symbol of entry PRS is read from entry register and recorded as I symbol of exit PRS, and number n i  of initial PRS symbol subject to interlacing is calculated by recurrent rule n i  =f(n 0 ,k,n i-1 ), i=1…N max , at that structure of exit PRS is defined through value of initial setting of interlacing device p 0  and through value of integer multiplier k=1, 2, 3… which are constant in the whole range of interlacing, and formation of N max  symbols of exit PRS is cyclically repeated to generate continuous PRS of interlacing. 
     EFFECT: increased structural security of generated PRS, reduced level of side lobes of VKF PRS of single set.
