Abstract: FIELD: physics. 
     SUBSTANCE: invention relates to control of resistance (strength) of materials and their protective coatings under action of concentrated flows of substance and energy. Essence: placing a sample with a test material in a liquid medium in front of the end surface of the emitter of ultrasonic oscillations, providing oscillations at the ultrasonic frequency, cavitation process is formed in the gap between the end surface of the radiator and the sample and is implemented for a time sufficient for destroying the surface of the analyzed material, and cavitation resistance is determined by change of thickness of analyzed material. Ultrasonic vibrations are introduced into the liquid medium through a radiator which is multiple along the length of half the wavelength and made of a thermo- or chemically resistant material. A portion of the working tool, which is a multiple of the length of a quarter of the wavelength, is placed in a medium with abnormal conditions of chemical activity, temperature or pressure, and another multiple quarter-wave length of part of tool on side of connection with piezoelectric transducer is placed under normal conditions and provides its cooling. Amplitude of vibrations of end surface of working tool in liquid medium with abnormal conditions is set by current value of mechanical branch of piezoelectric transducer. In the course of the cavitation process implementation, the cavitation medium cavity resistance change rate is continuously monitored based on the measured values of the mechanical branch and voltage current on the piezoelectric transducer and its value is compared with the value of the rate of change of wave resistance of water under normal conditions and their equality is established by moving the sample with the test material in the direction to the end surface of the radiator. Minimum power supply voltage value is set sufficient to provide preset speed of wave resistance variation at minimum amplitude of oscillations. 
     EFFECT: higher reliability of research results and enabling correct decisions when selecting materials for operation under cavitation conditions in conditions which are abnormal by temperature, pressure and degree of aggressiveness.

Abstract: Die Erfindung betrifft ein Verfahren zum Verfluessigen von Kohle, bei dem die Kohle mit Anreiboel zu einem Brei verruehrt, auf Druck gepumpt, vorgewaermt und dann in einer Reaktorzone in Gegenwart von Wasserstoff und gegebenenfalls Katalysator verfluessigt wird. Das die Reaktorzone verlassende Dampf-Fluessigkeitsgemisch wird dabei in einem Heissabscheider einer Phasentrennung unterzogen. Die bei der Phasentrennung anfallende fluessige Fraktion des Heissabscheiders wird ohne Entspannung einer Verkokungszone zugefuehrt und in dieser in Gegenwart von Wasserstoff unter etwa dem Druck des Heissabscheiders verkokt. Durch die erfindungsgemaesse Verkokung faellt neben dem Koks ein duennfluessiger, stabiler Destillat-Teer an, der zwar sehr aromatisch ist, aber kaum Asphalthene enthaelt. Dieser stabile Teer eignet sich in hervorragender Weise zum Anmischen der frischen Kohle, da er nur eine sehr geringe Polymerisationsneigung aufweist. Darueber hinaus kann dieses Verkokungsprodukt aber auch direkt der Weiterverarbeitung, zum Beispiel zu den in der Praxis geforderten Benzin-, Heizoel- und sonstigen Schnitten, in fest angeordneten Katalysatorbetten zugefuehrt werden. Als weiterer Vorteil kommt hinzu, dass nunmehr keine dem hohen Verschleiss unterworfene Drosselventile mehr erforderlich sind.                                                                                                                                                                                             ...U.S.W

Abstract: The time-resetting device comprises means of control of the motor (29), means of inverting the polarity of the drive pulses (25) and a circuit (39) for detecting the position of the rotor of the stepper motor given the position of the polarity-inverting means (25). This detector circuit operates only during the first period after the cessation of the state for resetting the divider to zero, and it then delivers a detection signal which, depending on the situation detected, does or does not comprise a detection pulse. The latter is applied to an inverter control circuit (19) which acts on the polarity-inverting means (25) so that they effect a further permutation in the event that the detection means register a position of the rotor such that, without prior inversion, the next advance pulse would not be able to make the latter advance. <IMAGE>
