Abstract: The present invention is for a vacuum imaging drum with vacuum holes for maintaining a boundary layer in an image processing apparatus (10). The image processing apparatus (10) with a vacuum imaging drum (300) for holding thermal print media (32) and donor sheet material (36) in registration on the vacuum imaging drum (300). A printhead (500) moves along a line parallel to the longitudinal axis (X) of the vacuum imaging drum (300) as the vacuum imaging drum (300) rotates. The printhead (500) receives information signals and produces radiation which is directed to the donor sheet material (36) which causes color to transfer from the donor sheet material (36) to the thermal print media (32). The vacuum imaging drum (300) provides vacuum on its surface by means of a first plurality of holes. A second plurality of holes maintains a boundary layer (336) of air along the drum surface.

Abstract: A multi-element housing is disclosed for the containment of multiple membrane separation elements in parallel. The multi-element housing is characterized in that the elements are grouped in parallel with a feed/retentate zone, defined by a space enclosed by two tube sheets arranged at the same end of the elements. The central mandrels of the elements pass through the feed/retentate zone space defined by the two tube sheets and empty permeate outside the defined space into a permeate collection zone from which it is removed, while the tube sheet directly attached to the element is in open relationship to the interior of the membrane element and retentate accumulates in the space between the top tube sheet and the bottom tube sheet from which it is removed.
