    摘要： A check valve includes a valve housing having a valve cover, a valve seat and spring loaded valve diaphragm with a valve spindle, and base for the valve spindle. The free end of the spindle is made in the form of a piston and the valve spindle cover is in the form of a cylinder through which a blast of control gas enters.

    摘要： A seal for the partition wall between the liquid feed and the discharge tube in columns with circular flow at the contact places of the wall with the column jacket and inner tube is characterized by at least one guide piece fastened to the partition wall with a sealing tongue slidably supported therein, which is pressed by a spring to the column jacket and the inner tube.

    摘要： An improved tray for rectifying and scrubbing columns is simply constructed by providing a cylindrical member coaxially within the column shell, placing beams radially between said member and shell, attaching one end of each beam to said member or shell, supporting the opposite free end of each beam on a ring fastened to the vertical surface adjacent to said free end, and fitting tray segments in locking arrangement between the beams which are circumferentially spaced from each other. The free ends of the beams supported on the ring, together with the locked-in tray segments, can move radially to accommodate differences in thermal expansion of the components of the column.
