  • Patent number: 7094352
    Abstract: A column comprising a first end (2a) provided with a column packing means and a second end (2b) provided with a fluid collection means for collecting fluid from over some or all of the internal cross-section of the column, wherein said first and second ends (2a, 2b) are held apart by a column wall. The second end (2b) is provided with blocking means (52, 72, 82, 92) movable between a blocking position where said blocking means (52, 72, 82, 92) substantially obstructs the collection of fluid from a predetermined portion (CR, CR1, CR2) of the cross-section of the column and an non-blocking position where it does not substantially obstruct the collection of fluid from the predetermined portion (CR, CR1, CR2) of the cross-section of the column. This allows the resistance to flow through the collection means to be modified to control where the bed media is deposited over the cross-section of the column.

  • Patent number: 6006713
    Abstract: A hollow valve for internal combustion engines, comprising a valve body having a disk, a hollow throat region and a stem component, wherein the valve body is designed in the form a deep-drawn metal part made of austenitic metal. There is a stem end piece welded to the stem component of the valve body and a cover welded to the disk. The valve body, end piece and cover enclose a hollow space extending from the stem end piece into the disk. This valve is considerably lighter in weight than traditional valves, and is capable of lowering the temperature of the valve when the hollow space is filled with a coolant.
