Картонный материал содержит картонное полотно, содержащее древесные волокна и диспергированные среди волокон расширенные микросферы, имеющее теоретическую плотность ориентировочно от 0,38 до 0,64 г/см 3  и толщину листа от 609 до 889 мкм, при прочности внутреннего сцепления по меньшей мере около 168×10 -3  кДж/м 2 , а преимущественно по меньшей мере около 210×10 -3  кДж/м 2 . Для таких применений, как чашки, указанный материал имеет на одной или обеих сторонах барьерное покрытие, которым преимущественно является полиэтилен низкой плотности, предназначенное для ограничения проникновения жидкости в картонное полотно. Поверхность картона низкой плотности имеет чистоту поверхности по Шеффилду около 300 SU или больше по сравнению с чистотой поверхности от 160 до 200 SU для обычного сырья для изготовления чашек, что раньше считали необходимым для обеспечения хорошего качества печати. Картон низкой плотности обеспечивает хорошее качество печати на флексографической печатной машине, несмотря на относительно низкую чистоту поверхности, что является неожиданным преимуществом картона, вместе с его изоляционными и прочностными свойствами. 6 н. и 34 з.п.ф-лы, 5 ил., 3 табл.

Abstract: FIELD: hydraulic engineering; fish protective facilities. 
     SUBSTANCE: invention is designed to draw off young fish from zone of influence of water diversion front. Method comes to ejecting young fish into intake part of ejecting plant from section of pond with higher concentration of young fish, creating active ejecting working stream in mixing chamber by entraining volume of water containing young fish into stream created by central ejecting hydraulic jet and further conveyance of water-fish mixture along pressure conduit into fish outlet. At the last stage of conveyance young fish is transported into fish outlet under no pressure conditions by forming hydraulic jet angle to trough of fish outlet, young fish being dropped on surface of fish outlet stream. Invention provides effective conditions for drawing off young fish into fish outlet and reduces damage to young fish. If working ejecting stream is preliminarily saturated with atmospheric air, its outer borders are saturated with air in form of finest microbubbles which form boundary layer ("air cushion") at contact with which young fish do not suffer from discomfort and easily take up hydrodynamic pressure built in mixing chamber. Moreover, provision of boundary layer saturated with microbubbles of air makes it possible to considerably reduce value of friction coupling of two streams, main getting from working nozzle and ejecting, containing young fish. 
     EFFECT: provision of good conditions for letting out young fish into fish outlet, reduced damage of young fish.

Abstract: FIELD: nuclear power engineering. 
     SUBSTANCE: the method of resistance spot welding, mainly of the spacing grates of nuclear reactors, is realized by a modulated unipolar pulse of the welding current.  In this case the current-conducting section is produced at the constant force of compression of welding electrodes.  The contact resistance of this section is lesser than the contact resistance of cold articles, but greater than the contact resistance of the articles, welded by means of the current with the greater amplitude and lesser duration, than welding current.  The stabilization of the contact resistance is realized without formation of the cast core in the section of the welding circuit of "electrode-electrode" by means of passing the current at the lesser amplitude than welding current.  The article welding with production of the cast core is realized when passing the current at the amplitude, sufficient for formation of the cast core of given dimensions and further passing of the current at the lesser amplitude through a welded article.  Monitoring of the instantaneous values of voltage during the welding process is carried out.  The monitoring results are used for article rejection.  The rejected articles are rewelded by means of a more power current pulses without removing the welding force.  The duration of the part of the welding current pulse at the constant amplitude, ensuring the stabilization of the contact resistance is chosen as sufficient one for reaching the voltage constancy in the welding circuit.  The parameters of the part of the welding current, passing through the produced cast core after decreasing its maximum value of duration and amplitude, correspond to the parameters of the part of stabilization of the contact resistance.  Monitoring the disappearance the contact resistance of "article-article" is realized by comparison of the amplitude values of voltages during the indicated parts of the welding current pulse.  The existence of the cast core is determined by the voltage change rate during the horizontal part with the maximum amplitude of the welding current. 
     EFFECT: increased reliability of the welded spacing grates of the fuel elements of nuclear reactors.
