Abstract: Изобретение относится к области машиностроения, в частности к устройствам для обработки топлива электрическими полями перед подачей его на сжигание. Предложен электроимпульсный ионизатор топлива, содержащий полый диэлектрический корпус 2 в виде осесимметричного цилиндра с входным 7 и выходным 1 штуцерами, образующий ионизационную камеру 9, в которой размещены электроды 4, 8, подключенные к источнику высокого напряжения. Электроды 4, 8 попарно размещаются в сечениях, перпендикулярных оси симметрии цилиндрической части ионизационной камеры 9, при этом электроды каждой пары ориентированы диаметрально противоположно друг к другу и попарно подключены к разным полюсам импульсного преобразователя высокого напряжения 3, который генерирует и поочередно подает высокое напряжение к очередной паре диаметрально противоположных электродов в последовательности, направленной в сторону движения топлива. Частота подаваемого на электроды высокого напряжения находится в области частот собственных колебаний молекул топлива, что формирует между комплектом диаметрально противоположных электродов пульсирующее объемное электрическое поле высокой напряженности, состоящее из набора однородных электрических полей высокой напряженности, возникающих между каждой парой электродов.

Abstract: FIELD: railway equipment. 
     SUBSTANCE: invention relates to railway equipment and can be used for automated driving of freight trains of increased weight and length, in which several locomotives are used, which are distributed along train length, including connected trains. Method for automated driving of freight trains of increased weight and length with locomotives distributed over the length of the train consists in the fact that in case of communication between the driving and driven locomotives along the main or backup channels, generalized modes of train driving are determined on the leading locomotive with their transmission through communication channels to the slave locomotives in the form of a task. In absence of communication between driving and driven locomotives along main and backup channels during time exceeding total duration of two receiving packages, driven locomotives switch to autonomous operation with independent selection of generalized modes of conducting a train and using own databases and readings of their instruments, and performing autonomous operation until communication is restored. Group of inventions also relates to a system for automated driving of freight trains of increased weight and length with locomotives distributed throughout the length of the train. 
     EFFECT: increased reliability of operation at loss of communication between locomotives.

Abstract: FIELD: electricity. 
     SUBSTANCE: group of inventions relates to high-current switching equipment and can be used for formation in low-impedance loads of multi-megampere current pulses with rise time of the order of one and less microseconds. In the method of creating multichannel electrical breakdown of a solid-state insulator with artificially created inhomogeneities in the main gap between two electrodes, the solid-state insulator in the main gap is divided by a metal foil into two auxiliary interelectrode gaps, applying voltage to electrodes of main interelectrode gap and using artificial inhomogeneities provide conditions for single-channel breakdown in first auxiliary interelectrode gap and thereby causing a voltage jump in the second auxiliary gap with a sufficiently steep edge for occurrence of multichannel electrical breakdowns in the insulator in places of artificial inhomogeneities, as a result of which cumulative jets are formed in these places, which extend beyond the limits of the second auxiliary gap, piercing the insulator in the first auxiliary gap, thereby electrically closing the main gap between high-voltage electrodes in many channels. In the device containing high-voltage electrodes, fed from a high-voltage source and separated by a main gap with a solid-state insulator with artificially created irregularities, high-voltage electrodes are made in the form of two coaxial plane-parallel discs, and non-uniformities are made in form of metal shells embedded into insulator, each of which is electrically connected to one of high-voltage electrodes, wherein in the solid-state insulator coaxially and in parallel to the electrodes there is a flat disc of metal foil dividing the main gap into two auxiliary gaps, in first auxiliary space there is one metal shell located on the axis, fused into insulator, and in the second auxiliary space there are metal shells equally spaced from the foil and placed at the same distance from the axis. Gaps between the foil and electrodes, foil and the fused shells are selected such that when the voltage on the electrodes rises, breakdown occurs first in the first auxiliary space between the foil and the metal shell on the axis. 
     EFFECT: broader operational capabilities owing to formation of a multichannel breakdown of a solid-state insulator using conventional high-voltage sources with a rate of increase of less than 10 11  V/s and a reduction in the dimensions of the device.

Abstract: FIELD: technological processes. 
     SUBSTANCE: invention relates to a method of laser deposition of metal coatings and can be used in formation of protective slurry coatings on structural materials. Prepreg based on a polyamide fabric impregnated with a caking polymer composition is applied on the metal surface. Tissue is decomposed to form active nitrogen and is converted into a single macromolecule containing simultaneously boron, titanium and nitrogen atoms in stoichiometric ratio and a catalyst when forming nitrides – a carbon atom. Prepreg under decomposition of temperature generated by laser beam destructs, releasing highly active atoms of boron, titanium, nitrogen and carbon, which react in a medium of porous coke, forming a mixture of titanium and boron nitride with impurities of heat-resistant carbides similar in melting point. Temperature is then increased to 16,000÷1,800 °C. At that, coke and impurities are destructed, and on surface of iron-carbon alloy there is a lighter layer of solid particles, melting point of which is close to 3,000 °C. Thickness of the protective layer is adjusted by the number of prepreg layers. Application of the composition onto the polyamide fabric is controlled by the viscosity of its solution and the speed of drawing the fabric on the impregnating machine. 
     EFFECT: technical result of the invention consists in improvement of antifriction properties of iron-carbon alloys under conditions of action of high and ultrahigh temperatures due to formation on the surface of alloys of a layer from a mixture of nitrides of boron and titanium of the specified adjustable thickness.
