Стабилизация диодного лазера осуществляется по положению пика линии поглощения измеряемого газа по составляющей на частоте 3f с точностью до 10-4см-1. По сдвигу фаз вычисляется расстояние до рассеивающей излучение лазера поверхности. Технический результат заключается в увеличении чувствительности, уменьшении массогабаритных характеристик и обеспечении возможности установки газоанализатора на беспилотные летательные аппараты. 2 н. и 3 з.п. ф-лы, 6 ил.

Abstract: FIELD: medicine; mammalogy. 
     SUBSTANCE: invention relates to the field of medicine, namely to mammalogy, specifically to the differential diagnostics of the mammary gland. Palpation of the mammary gland is performed in two stages. At the first stage, the phalanges of the fingers are pressed through the mammary gland to the chest and the fingers are shifted together with the skin to determine the uniformity of the mammary gland tissue, performing manipulation over the entire area of the mammary gland. At the second stage, the thumbs are placed on the chest, and the other four fingers grab a piece of tissue, and by sorting through the fingers, move the fold along the mammary gland. If the tissue inside the mammary gland is dense, then the thickness of the fold increases. The results of a bimanual study of the mammary gland density are evaluated in points according to a five-point system. The density of each of the mammary glands, the detected local density or local increase in the fold more than twice in comparison with other parts of this mammary gland is estimated at 4 points. Dense heterogeneous tissue, when it is not possible to conduct a study with a "fold", is estimated at 3 points. Dense tissue in the upper-outer quadrant with contouring of the edge of the gland and an average uniform density of the remaining quadrants, with a fold of 4-5 cm, is estimated at 2 points. The uniform density over the entire gland with a fold of 3-4 cm is estimated at 1 point. A soft uniform tissue on both sides, with a fold of 1-3 cm, which is freely rolled in all quadrants, is rated at 0 points. At the same time, a score of 3-4 points during a manual examination of the mammary gland is a reason for conducting an extraordinary examination.   
     EFFECT: method allows systematizing the palpatory examination of the mammary gland with an assessment in points for dynamic control at the primary stage of manual examination in the differential diagnostics of the mammary gland.

Abstract: FIELD: heat exchange technology.  
     SUBSTANCE: invention relates to heat exchange technology, methods and devices for the environmentally safe thermal destruction of solid medical waste containing organochlorine components, and can be used in processes with waste high-temperature dusty gases. The solved technical problem: high-speed, up to 1500°C/s, gas cooling with its simultaneous dedusting. A method for solving the technical problem: cooling of a dusty high-temperature gas is carried out by its interaction with a cold gas flow in the mode of vortex interaction of two counter-displaced swirling flows, during which the trajectory of the cooled gas mixture is arranged in the form of a narrowing, rotating vortex flow, which ensures the separation of solid inclusions from it due to centrifugal forces. The device that ensures the achievement of the expected result contains a vertical housing with a lid, gas inlet and outlet pipes and a solid particle outlet device. The upper cylindrical part of the housing is equipped with two inlet pipes for cooled and cooling gases, introduced in the same plane, tangentially from opposite directions. The diameters of the nozzles are the same and equal to 0.43 of the diameter of the housing. The height of the cylindrical part of the body is equal to 1.5-2.0 of its diameter. The lower part of the body has the shape of a cone and is equipped with a solid particles collection chamber with a sluice device for unloading them. Inside the cylindrical part of the housing, the confuser of the outlet of the cooled gas mixture is coaxially located, the inlet section of which is located at a distance of 0.3-0.7 of the diameter of the cylindrical part of the housing vertically from the axis of the inlet pipes and has a diameter of 0.7-0.9 of the diameter of the cylindrical part. The cooling gas pipe is equipped with a regulating device with a fan.  
     EFFECT: high-speed, up to 1500°C/s, gas cooling with its simultaneous dedusting.

Abstract: FIELD: shipbuilding. 
     SUBSTANCE: invention relates to the field of shipbuilding, in particular to submarines, floating in ice conditions and destroying the ice cover by the resonance method when they emerge in solid ice. The proposed method for the destruction of the ice cover by an underwater vessel consists in the excitation of flexural-gravitational waves in the ice when the vessel moves under the ice at a resonant speed. During the movement, the ship is given a bluff shape by the formation of hydrodynamic vortices at its aft end, and the centers of the vortices are located above the regions of separation of the boundary layer of the liquid flowing around the ship's hull. The vessel is given a streamlined shape periodically with a frequency equal to the frequency of resonant flexural-gravitational waves for a time equal to half the period of these waves. 
     EFFECT: increased efficiency of destruction of ice cover.

Die Aktivierung geschieht hierbei ueber die Reaktionen: - Ca-48(n,gamma)C-49 und - P-31(n, alpha)Al-28. Dazu sind thermische und schnelle Neutronen erforderlich, da die (n, alpha)-Reaktion eine Schwelle bei 2 MeV aufweist.

Abstract: Bei einem Gerät zum Bedrucken, Ausgeben und Anbringen von auf einem Trägerband haftenden Selbstklebeetiketten wird das Trägerband mittels einer Transportvorrichtung schrittweise um eine Spendkante gezogen, die von auf einer Achse gelagerten Röllchen gebildet ist und an der sich die Selbstklebeetiketten vom Trägerband ablösen. Damit ein sauberes Ablösen der Selbstklebeetiketten erreicht wird, muß die Spendkante eine möglichst scharfe Kante bilden, was bedeutet, daß die Röllchen einen möglichst kleinen Durchmesser haben müssen und demgemäß auf einer sehr dünnen Achse gelagert sein müssen. Damit unabhängig von der Etikettenbreite Röllchen mit Kleinem Durchmesser verwendet werden können und dennoch Auswirkungen des Reibmoments zwischen Röllchen und Achse gering gehalten werden, wird die die Röllchen tragende Achse zwischen ihren Enden abgestützt.
