Abstract: FIELD: foundry, particularly, methods for manufacture of machine parts with single-crystal structure, for instance, blades by oriented crystallization. SUBSTANCE: mold is installed into preheating chamber, heated and moved to metallization chamber. Then mold with metallized surfaces is moved to heating chamber in which it is located horizontally with its longitudinal axis. Melt is poured into mold. Mold with melt is placed into cooling chamber for formation of oriented or single-crystal structure in casting. Metallization of mold and cooling are performed under effect of two flows of mixtures of inert gas and powdery cooling agents from materials undergoing phase conversions with heat abstraction. Each chamber has appliance for transportation of molds in horizontal plane. Located beyond chambers are vacuum and gas system and systems of formation of cooling flows. Located in chambers are system of direction of cooling flows, systems of mold heating and melting.

Granted: 2002-11-10
Abstract: Изобретение относится к электротехнике, а именно к устройствам для сигнализации срабатывания устройств защиты электропитания. Технический результат заключается в обеспечении достоверности контроля работы самовосстанавливающегося предохранителя. При срабатывании самовосстанавливающегося предохранителя (1) рабочее напряжение (постоянное или переменное) через ограничивающий резистор (2) и выпрямитель (3) поступает во входную цепь управления оптрона (4), открывая его. Сигнал с оптического выхода оптрона (4) инвертируется в первом инверторе (5) и переключает триггер (6) в другое устойчивое состояние. Этот же сигнал в блоке индикации (7), проходя через третий инвертор (12) и первый логический элемент И (13), включает красный светодиод (14), выключая зеленый светодиод (16). С прямого выхода триггера (6) запомнившийся сигнал о срабатывании предохранителя (1) поступает на вход управления генератора импульсов (9), а с инверсного выхода триггера (6) на вход блока переключения (11), включая сигнальное реле и передавая сообщение о срабатывании самовосстанавливающего предохранителя (1) в линию связи. С выхода генератора импульсов (9) через второй инвертор 10 сигнал поступает на вторые входы первого и второго логических элементов И (13,15). При этом красный светодиод (14) начинает мигать с частотой генератора импульсов (9). При самопроизвольном восстановлении самовосстанавливающегося предохранителя (1) в исходное состояние (в случае восстановления сопротивления нагрузки) зажигается зеленый светодиод (16) (красный светодиод (14) при этом гаснет). Но зеленый светодиод (16) мигает, сигнализируя о бывшем срабатывании самовосстанавливающегося предохранителя (1). На выходе блока переключения (11) остается сигнал включения сигнального реле. Восстановление исходного состояния устройства происходит при кратковременном нажатии кнопки "Сброс" (8). 1 з.п. ф-лы, 1 ил.
