    • A reactor 20 has a plurality of tubular downcomers 32, 34, 36, 38, 40 and risers 42, 44, 46, 48, 50, joined by sections 86, 88 in a continuous serpentine path the tubes dimensioned to provide substantially plug flow conditions for solid and liquid reagents fed into a first downcomer 24 with the products extracted from final riser 52. The reactor 20 is designed for a desired residence time by the number, height and diameter of the tubes. The downcomers 24, 32, 34, 36, 38, 40 may include a bend to improve residence time and to thereby reduce the number of tubes required for a desired overall residence time. The reactor 20 can be used in a leaching operation for producing synthetic rutile, where a pre-treated feedstock including ilmenite, leucoxene or titania slag is leached with hot HCl.
    • 反应器20具有多个管状下导管32,34,36,38,40以及在连续的蛇形路径中由部分86,88连接的立管42,44,46,48,50,所述管的尺寸被设计成提供基本的塞流量条件 用于固体和液体试剂,其进料到具有从最终提升管52中提取的产物的第一降液管24中。反应器20被设计成通过管的数量,高度和直径达到期望的停留时间。 降液管24,32,34,36,38,40可以包括弯曲以改善停留时间,从而减少期望的总停留时间所需的管的数量。 反应器20可以用于生产合成金红石的浸出操作,其中包括钛铁矿,二氧化锡或二氧化钛渣的预处理原料用热的HCl浸出。

    • A circuit breaker comprises a housing containing a trip mechanism, a handle coupled to the trip mechanism and movable between on and off positions, and a lock-off mechanism capable of holding the handle in its off position. The lock-off mechanism includes a base member adapted to be mounted on the circuit breaker housing adjacent the movable handle. A slide is mounted on the base member for movement to an advanced position in which a portion of the slide projects into the path of movement of the breaker handle for engaging the handle and blocks movement of the handle from the “off” position to the “on” position. In the retracted position of the slide, the path of movement of the handle is unobstructed by the slide. A key-operated lock is also mounted on the base, and a lock shaft is coupled to the lock and mounted for movement to a locked position in which the shaft engages the slide when the slide is in its advanced position to block retracting movement of the slide, thereby locking the breaker handle in its “off” position. In the unlocked position of the lock shaft, movement of the slide is unobstructed by the shaft, but the slide interferes with advancing movement of the lock shaft, thereby preventing the lock shaft from moving to its advanced position.
    • 断路器包括容纳跳闸机构的壳体,联接到跳闸机构并可在打开和关闭位置之间移动的手柄以及能够将手柄保持在其关闭位置的锁定机构。 锁定机构包括适于安装在邻近可移动手柄的断路器壳体上的基座部件。 滑动件安装在基座构件上以移动到前进位置,在该位置,滑块的一部分突出到用于接合手柄的断路器手柄的运动路径中,并阻止手柄从“关闭”位置移动到“ 在“位置上。 在滑块的缩回位置,手柄的移动路径不受滑块的阻碍。 钥匙操作的锁还安装在基座上,并且锁定轴联接到锁并且被安装成运动到锁定位置,在滑动件处于其前进位置时,轴与滑块接合,以阻止滑动件的缩回运动 滑动,从而将断路器手柄锁定在其“关闭”位置。 在锁定轴的解锁位置,滑块的移动被轴不通过,但是滑块妨碍锁定轴的前进运动,从而防止锁定轴移动到其前进位置。
