transverse plane of the second edge and a second end which is
closer to the transverse plane of said second edge than to the
transverse plane of the first edge,
said crossbars being arranged in at least two separate
intersecting oblique planes, each of which intersecting oblique
planes is disposed at an angle relative to said axis, there being a
plurality of said crossbars in each said plane, which crossbars of
each plane are spaced apart to provide openings for fluid flow and
wherein each respective crossbar is laterally connected directly to
an adjacent crossbar at respective ends thereof.
