Abstract: Предложенное изобретение относится к устройству и способу для прессования слоистой системы для изготовления панелей, предназначенных для полов. Прессующее устройство содержит две нагреваемые прессующие плиты, транспортно-захватные средства, средства перемещения нагреваемых плит к слоистой системе и ее прессования. С помощью транспортно-захватных средств слоистая система может захватываться и транспортироваться в положение между плитами прессующего устройства. Управление средствами перемещения выполнено таким образом, что обе нагреваемые плиты одновременно достигают слоистой системы и также одновременно удаляются от слоистой системы. Площадь плиты, посредством которой передается давление на подлежащую прессованию слоистую систему, составляет, по меньшей мере, 1 м 3 . Согласно способу изготовления панели слоистую систему с клеящим веществом подвергают в прессующем устройстве воздействию давления и температуры с двух сторон так, что за счет этого воздействия слоистая система склеивается, причем двухстороннее температурное воздействие для плавления клеящего вещества осуществляют одновременно. Из слоистой системы изготавливают напольные панели шириной, по меньшей мере, 300 мм, длиной, по меньшей мере, 800 мм и толщиной не более 15 мм, на боковых кромках которых выполняют фрезерованием шпунтовые пазы и гребни, выполняют дополнительное запорное средство, обеспечивающее соединение панелей без клея. Данное техническое решение позволяет предотвратить передачу тепла со сдвигом. 3 с. и 9 з.п. ф-лы, 2 ил.

Abstract: Изобретение относится к горной промышленности и может быть использовано для обеспечения безопасных условий труда в угольных шахтах. Техническим эффектом изобретения является предотвращение газовых всплесков путем применения глубокой дегазации массива. Для этого осуществляют проведение скважин и определение динамики изменения концентрации газа в исходящем из тупикового забоя воздушном потоке. В каждом цикле подвигания забоя выработки устанавливают продолжительность превышений предела измерения концентрации газа в воздушном потоке. Затем определяют объем газового всплеска и проводят мероприятия по предотвращению очередных проявлений последнего. Объем газового всплеска устанавливают по расходу воздуха, продолжительности всплеска и концентрации газа, которую определяют в точке пересечения экстраполируемых логарифмических линий во временных границах начала и окончания всплеска. При этом концентрацию газа, превышающую 100%, принимают за 100%. Мероприятия по предотвращению газовых всплесков осуществляют путем интенсификации процесса дегазации угольного массива впереди забоя выработки, для чего на угольный массив активно воздействуют через подземные скважины. Внедрение изобретения позволяет обеспечивать безопасные условия труда шахтеров в подготовительном забое и прилегающих к нему горных выработках путем проведения мероприятий по интенсификации процесса дегазации угольного массива с помощью подземных скважин. 4 з.п. ф-лы, 3 ил.

Abstract: FIELD: genetic and protein engineering, medicine, molecular biology, pharmacy. 
     SUBSTANCE: invention proposes a modified form of plasminogen urokinase type activator (activator) wherein amino acid sequence differs from that in the natural activator as result of replacing the sequence Arg-Arg-His-Arg-Gly-Gly-Ser in the composition of inhibitory loop for the sequence Arg-His-His-Ala-Gly-Gly-Ser and by replacing 24 N-terminal amino acids for the foreign sequence consisting of 16 amino acid residues. Invention proposes the constructed recombinant plasmid (pUABC 34) comprising DNA fragment that encodes a new activator. As result of transformation of E. coli K-12 JM109 cells with plasmid pUABC 34 the recombinant strain E. coli VKPM-8145 as a producer of a modified form of activator is obtained. This polypeptide is characterized by reduced sensitivity to effect of inhibitor PAI-1 and absence of some by-side effects in the complete retention of biological activity of the natural activator produced by the recombinant. This provides effective applying a new activator as a component of pharmaceutical compositions eliciting thrombolytic effect. 
     EFFECT: valuable medicinal properties of activator and pharmaceutical composition.
