Granted: 1998-11-27
Abstract: FIELD: nuclear reactors. SUBSTANCE: device is built around converging-diverging nozzle; it is, essentially, small-size item inserted in protected pipeline that bursts in case of accident to limit hot coolant flow within a few minutes sufficient to take measures for accident confinement. Uniform field of flow velocities is formed throughout entire sectional area of pipeline immediately downstream of limiting insert due to replacing one high-speed stream escaping converging- diverging nozzle and equal in its flow rate to pipeline flow by many small jets uniformly distributed over entire cross-sectional area of pipeline whose total rate equals pipeline flow. Reach distance of these jets equals maximum ten diameters of diffuser outlet sectional area in small converging-diverging nozzle which makes it possible to insert device in narrow spaces of pipelines just upstream of pipe valves such as upstream of check valve, without danger of its destruction by high-speed jet escaping converging-diverging nozzle. EFFECT: improved design. 2 cl, 4 dwg, 1 ex

Granted: 1999-01-10
Abstract: FIELD: sewing industry. SUBSTANCE: sewing-overstitching machine has casing, needle carrier, adjustable thread tightening device with immovable tension washers and movable tension washers which are pressed to immovable washers by variable-rigidity springs, regulators for changing spring force, and thread releasing device. Control lever of thread releasing device is formed as cover rotating in vertical plane and mounted in front of needle carrier. Cover is disposed in lower position during sewing process and in upper position in the process of charging thread into machine. Controlled thread tightening and releasing devices are positioned on cover. Immovable and movable washers of thread tightening device are aligned relative to cover axis of rotation. Variable-rigidity V-shaped springs for tightening movable washers are arranged along cover so that their one ends cooperate with slide-type regulators and other working ends cooperate with movable washers. V-shaped springs have mid portions provided with axially aligned openings extending in parallel with axis of rotation of cover. Thread releasing device ejector positioned in openings is spring-biased in the direction opposite to direction of action of working ends of V-shaped springs. When cover is in lower position, ejector free end comes into engagement with casing to be moved into cover. As a result, gap is defined between stops spaced along ejector body and working ends of V-shaped springs, which load movable washers with tightening force. When cover is in upper position, ejector is forced by related spring to opposite side to define gap between working ends of V-shaped springs and thread tightening movable washers, thus releasing threads to facilitate passage of threads along thread guiding channels of machine. EFFECT: simplified construction and increased safety of sewing machine. 4 dwg

Abstract: FIELD: medicine. SUBSTANCE: method involves exposing an area on intact dental tissue to helium-neon laser radiation through multiple-strand two-channel light guide. Reflected signal spectrum is recorded and intact tooth area fluorescence index (Ji) is determined. Jp fluorescence index is determined in the same way in all pathologically changed areas. Jp/Ji value being greater than 1 ± 0.2, active caries process and/or supra- or subgingival dental deposit case are diagnosed. Treatment is continued until Jp/Ji =1 ± 0.2, that is, until the whole injured area is removed. To evaluate canal cleaning effectiveness degree, Je as fluorescence index is measured on intact tooth dentin. Then fluorescence indexes are measured on canal entrance, its middle part and exit area, respectively. Normalized index J k1 ,J k2 ,J k3  is determined. Treatment is continued until K 1 = J k1 /J э ,K 2 = K k2 /J э ,K 3 = J k3 /J э .. The treatment being of low quality, K 1 =K 2 =K 3 =1±0,2. indexes are higher then Je value in intact area due to high concentration of fluorescent microflora available in the injured area Ji.
