Title: Method for producing napped patterns
IPC: D04H11/00
Filed: 2000-04-19
Granted: 2001-08-20
Abstract: FIELD: textile industry. SUBSTANCE: method involves applying each pile to adhesive surface of material; applying first pile on unit equipped with intermediate electrode having the intensity of nonhomogeneous electric field in lower zone of 1-8 kV/cm, with the result that pile forms pattern on adhesive surface under the action of nonhomogeneous electric field; placing material with applied first pile on flocking unit, where second pile had been preliminarily placed and intermediate electrode positioned, with second electrode having shape other than first electrode and the intensity being of substantially the same value; repeating mentioned procedures, with number of repeated procedures depending on the number of selected colors; positioning material with pattern of applied piles on flocking unit free of intermediate electrode; providing final flocking procedure at identical electric field intensity to cause fibers to fill remaining sites. Various patterns may be produced with intermediate electrodes of similar shape and different intensities of nonhomogeneous electric field in lower zone by varying intensity in lower zone at each pile applying procedure through altering the voltage supplied or distance between intermediate electrode and material. At second and subsequent pile applying procedures, piles of larger lengths may be applied for producing relief patterns on material. To obtain distinct relief, pile length ratio must be at least 1.5. Field intensity variation range permits usage of piles satisfying standard specifications and does not require special chemical treatment. Various combinations of colors, pile lengths, intermediate electrode shape and field intensity values provide for unlimited possibilities in pattern designs. EFFECT: simplified method and wider range of possible patterns. 2 cl, 1 tbl

Abstract: Изобретение относится к способам обезвреживания химических отравляющих веществ и может быть использовано для обеззараживания внутренней поверхности боеприпасов от остатков фосфорорганических ОВ типа "зарин" и "зоман". Внутреннюю поверхность боеприпаса предлагается обрабатывать реагентной композицией на основе органического растворителя и нейтрализующего компонента. В качестве нейтрализующего компонента предложено использовать моноэтаноламин, поскольку именно он является основой дегазирующих составов в технологиях уничтожения ФОВ типа "зарин" и "зоман". В качестве компонента для полного растворения шеллачного покрытия, смыва ОВ с поверхности и из приповерхностных слоев металла предложено использовать доступные, дешевые, пожаробезопасные органические растворители, образующие гомогенные смеси с моноэтаноламином, а именно хлороформ. Обработка внутренней поверхности боеприпаса после его расснаряжения и дегазации реагентной композицией на основе 5-8% раствора моноэтаноламина в хлороформе позволяет за счет использования хлороформа растворять защитное шеллачное покрытие боеприпаса и переводить в раствор остаточные количества сорбированных в нем отравляющих веществ, а моноэтаноламин нейтрализует их до концентрации не более 1•10 -5  мг/мл.

Abstract: Изобретение относится к технике защиты транспортных средств (ТС) от угона. При несанкционированном доступе в ТС охранной частью системы включают отпугивающе-предупредительную сигнализацию, а ее противоугонной частью блокируют работу двигателя и по радиоканалу передают сигнал тревоги владельцу ТС, а от него - сообщение о срабатывании противоугонной части в центр пейджинговой сети, где формируют по каналу пейджинговой связи сигналы воздействия на противоугонную часть. Радиоканал связи с владельцем ТС выполняют с возможностью автоматического контроля исправности, а канал пейджинговой связи - с возможностью воздействия на охранную часть. Отличие способа заключается в том, что перед подачей из центра пейджинговой сети сигналов на противоугонную часть передают по каналу пейджинговой связи сигналы на ее охранную часть, вводят систему в режим паники с включением дополнительных средств тревожной сигнализации, а выводят систему из данного режима с помощью Мастер-метки или набором секретного кода. При использовании злоумышленником радиобрелока или транспондера из центра пейджинговой сети по пейджинговому каналу отменяют поступление их сигналов на охранную и противоугонную части. Способ обеспечивает повышенную эффективность защиты ТС. 5 з.п. ф-лы, 1 ил.

Abstract: FIELD: processes and equipment for continuous steel casting. SUBSTANCE: tundish ladle includes receiving and discharging chambers divided by partition. Steel from tundish ladle is fed by protection pipe to suppressor-receiver mounted on ladle bottom in order to suppress kinetic energy of metal stream. Metal gradually fills receiving chamber and through overflow passages of partition it is fed to casting chamber. Overflow passages are cone ones. Passages of low and mean floors of partition are narrowed to side of casting chamber that is why rate of metal streams increases. Metallic inclusions are transported to upper layer of metal by means of bubbles of blown gas. Passages of upper floor of partition have inverse conicity that is why rate of metal streams decreases. It prevents attraction of non-metallic inclusions from slag to steel. Outlet portions of passages at side of casting chamber are in the form of protrusions. EFFECT: enhanced quality of removing non-metallic inclusions out of steel, improved strength of tundish ladle lining. 6 cl, 2 dwg, 1 tbl
