Abstract: FIELD: mechanical engineering; internal combustion engines. 
     SUBSTANCE: invention is designed for internal combustion engine wit having several cylinders, each provided with ignition coil for generating igniting spark in corresponding spark plug. Basing on signals from speed transmitter and phase sensor, cylinder is determined in which piston is in top dead center and cylinder in which piston is at expansion stroke. Said transmitter and second are connected with knocking control device which supplies knocking control signal of each cylinder separately to ignition control unit. Provision is made for activation of double ignition with igniting spark created in each cylinder each time when its piston reaches top dead center. According to invention, if phase sensor fails and if double ignition is not activated, knocking control device provides separate knocking control in each cylinder under normal conditions. If double ignition is activated at failure of phase sensor, knocking control is provided owing to emergency control with preventive change of ignition moment for all cylinders to delayed ignition or knocking control basing on common threshold knocking value for all cylinders is effected. 
     EFFECT: provision of complete combustion of working mixture in internal combustion engine and high degree of reliability of knocking control.

Abstract: FIELD: petrochemical processes. SUBSTANCE: mercaptans and diolefins are simultaneously removed from long naphtha fraction in column-type distillation reactor for distilling butane fraction. Mercaptans react with diolefins to form sulfides, which boil at higher temperature than topped C 4  and lighter part of naphtha. High-boiling sulfides are removed as distillation residues together with C 5  and heavier materials. The former are preferably fed into stripping column wherein a portion thereof is topped and heavier portion is removed with sulfides. Resulting decreased volume of naphtha may be hydrogenised to convert sulfides into hydrogen sulfide and diolefins, which may be hydrogenised into olefins and alkanes. EFFECT: increased degree of thioetherification. 11 cl, 1 dwg, 2 tbl

Abstract: FIELD: mining, particularly hydraulic underground seam fracturing, namely methods and devices to create fissures in uncased horizontal or vertical well. 
     SUBSTANCE: device comprises a number of units having rupture discs. Each disc is characterized by independent fracturing pressure, i.e. the first unit has lesser fracturing pressure in comparison with the second unit and corresponds to predetermined interval to be treated. The units are arranged in work string or well completion pipe string so that unit having lesser fracturing pressure is located at front end thereof or in the lowermost area. Next units have fracturing pressures increasing in direction from front pipe string end. As liquid is injected via pipe string pressure is increased to value exceeding fracturing pressure of the first rupture disc to provide processing liquid contact with seam. After the first horizon treatment or fracturing said horizon may be isolated. After that pressure may be repeatedly increased in pipe string and other discs may be ruptured.
