Title: Навигационный радиооптический групповой отражатель кругового действия с покрытыми алюминиевой фольгой гранями

Abstract: Изобретение относится к навигации и может использоваться на внутренних водных путях в составе плавучих буев для обозначения судового хода одновременно в радиолокационном и оптическом диапазонах волн. Технический результат - расширение функциональных возможностей. Для этого навигационный радиооптический групповой отражатель кругового действия с покрытыми алюминиевой фольгой гранями представляет собой групповой радиолокационный отражатель, содержащий восемь трехгранных уголковых отражателей с равными треугольными гранями, шесть из которых расположены вокруг вертикальной оси, проходящей через их вершины, и формируют круговую в горизонтальной плоскости диаграмму рассеяния в радиолокационном диапазоне волн. При этом отражающие треугольные грани всех шести трехгранных уголковых отражателей покрыты светоотражающим покрытием, выполненным в виде алюминиевой фольги, а в их вершины установлены шесть источников света, выполненные в виде светоизлучающих диодов, формирующих круговую диаграмму светорассеяния в оптическом диапазоне волн. Источники света питаются от источника питания постоянного тока и управляются фотоавтоматом управления сигнальным огнем. Таким образом, технический результат заключается в расширении функциональных возможностей в оптическом диапазоне волн внутренних светоотражающих поверхностей треугольных граней, покрытых алюминиевой фольгой радиооптического группового отражателя, обусловленных обеспечением подачи им светосигнальных огней с белым, красным, желтым или зеленым цветами свечения при использовании одних и тех же внутренних светоотражающих поверхностей треугольных граней. При этом цвет сигнального огня задается только типом светоизлучающих диодов и определяется сложившейся навигационной обстановкой на внутренних водных путях. 4 ил.

Abstract: Изобретение относится к машиностроению, а именно к двигателям внутреннего сгорания. Камера сгорания двигателя внутреннего сгорания с воспламенением от сжатия образована поверхностью цилиндра, поршнем со ступенчатой поверхностью днища, и крышкой цилиндра. В крышке цилиндра установлена перегородка, разделяющая при пуске двигателя камеру сгорания на два изолированных объема: основной и дополнительный, в котором создается повышенная степень сжатия вследствие того, что поршень имеет выступ, входящий в дополнительный объем при положении поршня в ВМТ. Перегородка изготовлена из материала, обладающего эффектом памяти формы. Перед пуском двигателя перегородка имеет низкую температуру, отогнута от поверхности крышки цилиндра и расположена вертикально, образуя дополнительную камеру. После пуска двигателя и появления в цилиндре открытого пламени перегородка нагревается, в ее материале происходит мартенситное превращение, и перегородка изменяет свою форму, прижимается к поверхности головки цилиндра и располагается горизонтально, открывая весь объем камеры сгорания. Изобретение обеспечивает повышение надежности пуска двигателя внутреннего сгорания. 2 ил.
