Abstract: Изобретение относится к техническим средствам реабилитации инвалидов по зрению и позволяет им самостоятельно передвигаться в незнакомой местности. Изобретение обеспечивает возможность слепому человеку самостоятельно ориентироваться в незнакомой местности, получать информацию о дальности обнаруженного предмета и опознать его. Это достигается тем, что в устройстве применена оптика с использованием профиля Френеля и лазерного излучателя. Приемник выполнен в виде шестиплощадочной линейки, которая совмещена по длине с оптической осью. В устройство введен магнитный компас, шкала которого индицируется звуковыми колебаниями. Сигнал от каждой фотоплощадки кодируется своим кодом и заполняется звуковой частотой, определяемой положением магнитной стрелки. Логарифмический блок регулирует громкость звуковых кодов в зависимости от отражательной способности предметов препятствия. Устройство может комплектоваться звуковым шагомером. 3 ил.

Abstract: The enclosure of the metallurgical container is connected to a fan (105) by a suction duct (102). An additional gas is introduced in the suction part of the fan (105), preferably by means of the duct (102). The flow rate of introduction of this additional gas is adjusted so that the gas pressure in the suction part of the fan (105) is kept at a fixed value, by virtue of a regulation value (108) preferably placed on an additional duct (107), connected to the suction duct (102). A control means (110) makes it possible to adjust the opening and closing of the regulation valve (108) so as to keep constant the gas pressure in the suction part of the ventilator (105).
