摘要： A pair of closed loop tracks provides a stationary slideway for slide (transparency) holders which are hinged together sequentially in an endless loop arrangement. A particular slide is selected for viewing by advancing the holders in the slideway to a viewing position at which the selected slide is reoriented from a normally radial to a peripheral orientation. Illumination from a source at the axis of the slideway permits viewing without extraction of the slide from the track.

摘要： Gas purification apparatus including reactant tanks into opposite ends of which mainstream and purge gases are introduced in a reciprocal operation are equipped with a purge gas heating arrangement for increasing the efficiency of the purge operation and a depressurizing arrangement for reducing the breakdown of reactant granules in these tanks. A simple control circuit in which a timing portion is removable for replacement with a leak test control panel is also described.
