Abstract: SUBSTANCE: vaccine corresponds to actual virus A/Johannesburg/33/94 (H3N2) by its antigenic properties. Vaccine strain A/47/Johannesburg/94/1 is a reassortant and obtained by breeding epidemic virus A/Johannesburg/3/94 (H3N2) with cold-adapted temperature-sensitive virus A/Leningrad/134/17/57 (H2N2) as an attenuation donor. Strain is harmless for adult and children. Strain A/17/Johannesburg/94/1 is actively multiplied in developing chicken embryos at optimal temperature 32-34 C and shows temperature-sensitivity and cold-adaptability. Reassortant inherited two genes encoding surface proteins (hemagglutinin and neuraminidase) from epidemic virus and six mutant genes encoding nonglycosylated proteins from attenuation donor. Strain A/17/Johannesburg/94/1 (H3N2) is areactogenic for adult (18-20 years age) at intranasal route of administration. Vaccine strain A/17/Johannesburg/94/1 corresponds to requirements by its biological property and reactogenicity index. EFFECT: strain indicated above. 1 tbl

Abstract: Изобретение относится к деревообрабатывающей промышленности и может быть использовано для фрезерных станков. В корпусе шпиндельного узла выполнены две кольцевые канавки с углом охвата 90 o , которые расположены своими осями симметрично в перпендикулярном направлении подаче заготовки. В зависимости от желаемого качества обработки редукционным клапаном устанавливают необходимую величину давления масла, которое подается от гидростанции в канавки. Масло, поступая в две кольцевые канавки, оказывает давление на наружное кольцо подшипника, создавая местный дополнительный натяг, что приводит к сжатию траектории оси шпинделя в направлении, перпендикулярном подаче заготовки. Это приводит к уменьшению величины ступенек между цилиндрическими поверхностями обработки поверхности детали, а следовательно, качество обработки поверхности повышается. Величина давления масла, подаваемого в канавки, должна ограничиваться величиной, когда повышенный натяг начинает приводить к снижению долговечности. Устройство способствует повышению качества фрезерования древесины. 2 ил.
