摘要： PCT No. PCT/RU94/00210 Sec. 371 Date Jun. 25, 1997 Sec. 102(e) Date Jun. 25, 1997 PCT Filed Sep. 5, 1994 PCT Pub. No. WO96/07897 PCT Pub. Date Mar. 14, 1996The invention relates to the oil refining and petrochemical industry and concerns, in particular, techniques for determining the knock rating of motor fuels. The proposed method of determining the knock rating of motor fuels involves thermostatic control of a reaction vessel of constant volume, feeding the fuel-air mixture into the vessel, atomization of the mixture under excess pressure and ignition of the mixture. The knock rating is calculated by the knocking intensity which is determined by the value of the signal from a knock sensor installed in the reaction vessel. The proposed apparatus for determining the knock rating of motor fuels comprises a reaction vessel with inlet and outlet valves and a thermostatic controller. A spark plug is installed in the reaction vessel and a knock sensor is arranged opposite the spark plug.

摘要： The present invention relates to a radiating gas burner having a burner nozzle in the shape of a metallic-felt porous body, wherein said body is made of a refractory heat-resistant alloy having a fully open variable-thickness volume porosity ranging from 90 to 98 %. The average size of the pores along the thickness of the burner nozzle ranges from 50 to 1000 mu m and decreases in the direction of the protection lid. Discrete fibres extend above the upper surface at a given angle relative to said lid. The metallic-felt porous body is mounted within a support housing made of a refractory material.

摘要： The 8 kW refrigerating system comprises a condenser, evaporator and two-stage centrifugal compressor assembly with an electric motor provided with a cooling system. The condenser inlet is connected to the compressor assembly outlet, while the condenser outlet is connected via the first and second choke elements to the inlet of the evaporator and to the cooling system. The evaporator outlet communicates with the compressor assembly inlet, the cooling system outlet communicates with the inlet of the second stage of the assembly. The cooling system is provided with a cooling skirt whose cavity lies between the stator and housing. The system is provided with a separator vessel, a recuperative heat exchanger and a heat-regulating valve controlled by the coolant pressure and temperature at the cooling skirt inlet and fitted in series with the separator vessel in the line connecting the condenser inlet to the evaporator. The separator vessel is connected by the gas phase to the coolant feed duct. The heat exchanger is connected by the coolant to the line connecting the condenser outlet to the evaporator inlet via the separator vessel. The second choke element is a heat-controlled valve regulated by the pressure and temperature of the coolant in the coolant discharge line from the cooling skirt.

摘要： A hydraulic hammer for driving a pile into soil in which an impact weight is arranged for being driven with reciprocating motion along guideways in a casing by a double-acting hydraulic cylinder. A pump having a drain line and a pressure line is connected to drive a piston in the hydraulic cylinder. Two two-position valves connect a piston cavity of the hydraulic cylinder with the pressure line or the drain line of the pump. Each valve has a valving element whose front axial end bears against a seat along an annular contact surface when the valve is closed. The valves carry at their rear axial ends control pistons, each of which has a diameter smaller than the diameter of the contact surface of the valving element with the seat. The two valves are coaxially arranged in opposition to one another and control communication between the hydraulic cylinder and the pressure or drain lines of the pump. Each valving element is in the form of a cylinder sealingly accommodated in a valve body along its outer diameter, the size of which is close to the diameter of the contact surface of the valving element. A cavity located at the front axial end of one valving element is communicated with a cavity located at the rear axial end of the other valving element.
