Abstract: Изобретение относится к нефтедобывающей промышленности, в частности к способам одновременно-раздельной эксплуатации двух пластов скважины без смешивания продукции пластов. Обеспечивает расширение технологических возможностей за счет возможности перекачки длительное время продукции пластов, содержащих твердые механические частицы. Сущность изобретения: способ включает спуск и установку в скважине пакера между пластами, технологической колонны и лифтовой колонны, насосной установки с верхним и нижним насосами, соединенными штоком, а с устьевым приводом - штангами. При этом входы верхнего и нижнего насосов сообщены соответственно с надпакерным пространством и подпакерным пространством через всасывающий клапан, а выходы - с технологической колонной и колонной лифтовых труб. Придают рабочее движение устьевым приводом через полые штанги насосам и поднимают продукцию нижнего и верхнего пластов на поверхность по лифтовой и технологической колоннам. Насосную установку снабжают верхним и нижним винтовыми насосами, корпусы насосов спускают в составе лифтовой колонны, между которыми ниже сообщения с надпакерным пространством на лифтовой колонне сверху вниз установлены втулка с тарированным продольным каналом и пустотелый переводник, оснащенный дополнительным входом в виде выполненной на верхней поверхности входной воронки с гильзой, размещенной в полости переводника. В скважину параллельно лифтовой колонне спускают технологическую колонну, оснащенную снизу концевиком, до герметичного взаимодействия концевика с гильзой и сообщения с полостью переводника. В лифтовую колонну спускают на штангах соответствующие насосам верхний и нижний винты, соединенные штоком, который дополнительно оснащают глухим плунжером. Диаметры винтов и плунжера изготовлены уменьшающимися сверху вниз для прохода через не соответствующие им корпусы и втулку во время спуска, который прекращают после взаимодействия верхнего и нижнего винтов с соответствующими им корпусами насосов. Плунжер герметично перекрывает продольный канал втулки, отсекая выход нижнего насоса от входа верхнего насоса. Устьевым приводом винтам придают вращательное движение, в результате продукцию нижнего пласта через подпакерное пространство, всасывающий клапан, полость переводника посредством нижнего винтового насоса по технологической колонне поднимают на поверхность. Продукцию верхнего пласта через надпакерное пространство, лифтовую колонну посредством верхнего винтового насоса поднимают на поверхность. 2 ил.

Abstract: FIELD: agriculture. 
     SUBSTANCE: invention relates to the sphere of agriculture and plant cultivation. The method envisages wide-row joint seeding of gramineous and leguminous crops. The following year one ploughs the leguminous component under and provides for formation of the gramineous component seed grass stand for combined production of seeds and forage mass. Under the method the leguminous component is sown in autumn; in spring, at the time of its regrowth one provides for seeding the gramineous component represented by festulolium. Its seeds are mixed with potash fertilisers in an amount of 20-25 kg/hectare. After appearance of sprouts the grass stand crops are spayed with Baikal EM-1 bacterial fertiliser. After the leguminous component has been undercrop harvested for production of seeds the remaining grass mixture is cropped for production of forage which is followed by cultivation of the inter-row-spacings with the leguminous component ploughed under and the festulolium left to produce seeds. 
     EFFECT: proposed method enables reduction of expenditures on fertilisers, increased yield of leguminous and gramineous crops seeds, additional production of forage characterised by improved feeding qualities and enhance the soil fertility.

Abstract: Изобретение относится к дорожным непрерывным заградительным барьерам и может использоваться при обустройстве автодорог, автотрасс и мостов. Технический результат заключается в существенном увеличении удерживающей способности ограждения, снижении величины динамического прогиба и препятствовании изгибанию стоек за счет дополнительной деформации (растяжения) полимерной диагональной растяжки при воздействии на нее внешних сил и преобразовании кинетической энергии удара наезжающего автомобиля в относительное удлинение растяжки и тем самым более эффективное, по сравнению с аналогами, гашение скорости наезжающего транспорта до начала разрушения конструкции ограждения. Дорожное барьерное ограждение содержит, по меньшей мере, одну продольную металлическую балку, закрепленную через компенсаторы на нескольких вертикальных металлических стойках, заделанных в грунт-основание, и сонаправленные диагональные растяжки, которые своими передними по ходу движения автотранспорта концами прикреплены к балке, а задними концами - к основаниям стоек вблизи грунта. При этом растяжки сделаны из полимерной композиции на основе полиолефина. 6 ил.
