Abstract: FIELD: rubber industry. SUBSTANCE: invention relates to manufacture of process additive for use in tire and general mechanical rubber industries in order to increase adhesiveness of rubber compounds based on natural and synthetic rubbers. Colophony resin is obtained by modifying colophony, in particular mixture of tallow colophony and tallow pitch in weight proportion (10-90): (90-10), by formalin or paraform, or fumaric acid, or maleic acid, or maleic anhydride as modifying agent taken in amounts 0.5 to 10 wt parts per 100 wt parts of colophony in presence of 1.0 to 10.0 wt parts of calcium oxide. Preparation procedure consists in mixing tallow colophony with tallow pitch, heating mixture to 140-150 (r) ', stirring resulting melt and heating it 195-200 (r) ', adding CaO and ageing mixture for 3-5 h followed by adding modifying agent and conducting polymerization process for 5-6 h in vacuum with some amount of inert gas, after which final product is granulated. Thus obtained colophony resin increases adhesiveness of rubber compounds more than by 20%. Possibility of preparing product in granulated state allows automating its use. EFFECT: improved environmental conditions of operation and reduced cost price of produce. 4 cl, 10 ex

Abstract: FIELD: experimental aerodynamics. 
     SUBSTANCE: method refers to determining value of torque from torsion twisting angle. During test rudder angle of surface control elements is installed by means of intramodel torsion-provided drive and angle of rotation of drive output shift is measured. Hinge moment, which acts on surface control elements, is found from ratio of M = c·(δ-γ), where M is hinge moment acting on surface control elements, c is rigidity of torsion, δ is rudder angle of surface control elements, γ is turning angle of output shaft of drive. Device for measuring hinge moment has deformation pick-up placed inside the case. Deformation pick-up has elastic member, deformation/electric signal transformer, surface control elements turning motor and control unit provided with device presetting turning angle of surface control elements. Elastic member of deformation pick-up is made in form of torsion, deformation/electric signal transformer is made in form of transducers and axis surface control elements which axis is cinematically connected with end of torsion through output shaft of deformation pick-up. The other end of torsion is tightly connected with shaft of motor through input shaft of deformation transducer. Original variant of device has electric signals to be represented in analog form. The second variant of the device uses functional elements connected to each other by means of digital (pulse) signals. Preset discreteness of turning angle of step motor provides determination of turning angle of motor's shaft from number of control pulses when controlling electric pulse which allows to replace the step motor shaft angular co-ordinate transducer with electronic pulse counter. 
     EFFECT: reduced power consumption.
