Abstract
Abstract A tower-packing support plate is made from intermittently expanded sheet metal by braking the metal in non-expanded areas to form a plate with an undulating cross-section. Tower-packing support plates of different heights are assembled in a single tower. Tower-packing support plates, whether assembled from sections of the same or different heights, are assembled with the meeting edges of the sections directed upwardly.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
114 words
A tower of high gas-and-liquid handling capacity, provided with means for supplying gas and liquid thereto and having therein a support plate having packing elements thereon, for providing contact between the gas and liquid, which support plate is of undulating cross section and formed of units which comprise (a) areas of expanded sheet metal with openings formed of cross members and (b) areas which are not expanded, the size of said openings being suitable for supporting the packing elements, the support plate being broken in opposite directions along parallel lines with the bottoms formed of spaced unexpanded areas broken in the same plane to provide a bottom adapted to rest on a flat surface.
Claim 2
Dependent Claim
114 words
A tower of high gas-and-liquid handling capacity, provided with means for supplying gas and liquid thereto and having therein a support plate having packing elements thereon, for providing contact between the gas and liquid, which support plate is of undulating cross section and formed of units which comprise (a) areas of expanded sheet metal with openings formed of cross members and (b) areas which are not expanded, the size of said openings being suitable for supporting the packing elements, the support plate being broken in opposite directions along parallel lines with the bottoms formed of spaced unexpanded areas broken in the same plane to provide a bottom adapted to rest on a flat surface.
Claim 3
Dependent Claim
41 words
The tower of claim 1 in the support plate unit of which the expanded areas are of substantially the same width and the unexpanded areas are of substantially the same width and the distances between the brake lines are the same.
Claim 4
Dependent Claim
32 words
The tower of claim 1 the support plate unit of which includes a single brake in an unexpanded area between two spaced expanded areas, the edges of which unit are unexpanded areas.
Claim 5
Dependent Claim
19 words
The tower of claim 1 the support plate of which comprises units some of which are higher than others.
Claim 6
Dependent Claim
28 words
The tower of claim 1 the support plate of which is in sections, which sections at the middle of the tower are higher than those at the edges.
Claim 7
Dependent Claim
37 words
The tower of claim 1 in which support plate is of undulating cross section, and is composed of a plurality of units with the edges of two adjacent units in contact and slanting up toward one another.
