Abstract: The invention pertains to the field of power engineering and may be applied to convert kinetic and thermal energy of a working medium into mechanical work. The method includes swirling of a pre-compressed working medium, its expansion in an actuating device to produce mechanical work in the form of rotation of the shaft, and discharge of the working medium from the actuating device. The working medium is swirled in the actuating device along a spatial trajectory in the form of a conical helix, the projection of which on a plane positioned at an angle to the axis of rotation is a curve having at least two breakpoints.

Abstract: A method of increasing secondary power source capacity includes doping a compound into an electrolyte as an additive which binding energy is higher than binding energy of combinations that are formed at a secondary power source discharge, the compound being ZnKr or CdAr. The method can be used in manufacturing secondary power sources such as batteries for electrical machines, transport vehicles, and cars, and for power sources for portable and mobile electronic devices.

Abstract: The invention pertains to the domain of metallurgy in particular, thermochemical surface treatment of products made of metals, mainly steels, and their alloys and it can be used for products hardening for the purpose of their service durability increase. The method of improvement of mechanical properties of products made of metals, mainly steels and alloys on their basis includes products nitriding in the gas atmosphere containing nitrogen and-or its compounds in the presence of a catalyst. Together the product and the catalyst are subject to hot isostatic pressing with observation of conditions of the barometric and temperature impact that provides achievement of dislocations density in the product's volume that satisfies conditions of transition of a part of the product substance into the positron state of the Dirac matter.

Abstract: The invention pertains to a method for processing of liquid hydrocarbon raw materials. The method includes preliminary pretreatment of a flow of raw materials and further processing with fractionation. The pretreatment is performed by forming a primary flow of liquid hydrocarbon with the characteristics of a straight tubular laminar flow and then directing that flow through a spiral tubing at a velocity the maximal value of which maintains laminarity of the laminar primary flow through the spiral tubing. The laminary primary flow is fractionated following the pretreatment. The invention has applications to the field of petroleum processing and may find application in the petroleum and petrochemical industries, and in the field of fuel power engineering.

Abstract: The invention pertains to the field of petroleum processing and may find application in petroleum and petrochemical industries, in field of fuel power engineering. Method for processing of liquid hydrocarbon raw materials includes preliminary pre -treatment of raw materials flow and further processing with fractionation. The pretreatment is performed by means of forming of the primary flow with characteristics of a straight tubular laminar flow, whereupon the raw materials flow is forced into directed progressive rotary motion along vortex trajectory preserving laminarity, for this purpose it is directed to a spiral tubing while the primary flow the primary flow, is forced to move at a velocity the maximal value of which is on the boundary of vortex axile zone satisfies the conditions of achievement by the Reynolds number of critical values for tubular flow of liquid.
