Abstract
Abstract The packing can be used for mixing or for exchange processes in exchange columns. The packing comprises at least one group of layers perpendicular to the column axis which has deflecting surfaces connected to a central connecting bridge and which are bent outwardly of the bridge in alternating fashion to define a X-shape. The adjacent layers can be provided with outer bridges which are bent around to form hook-shape portions for engaging about an adjacent layer. The packing can be produced by simple stamping and bending steps.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
76 words
A packing for a mass transfer, direct heat exchange and mixing comprising a plurality of X-shaped profiled layers disposed at the outer longitudinal edges thereof in side-by-side parallel relation with each other, each said layer having a centrally disposed bridge, a first row of deflecting surfaces extending from one side of said bridge in alternating angular relation and a second row of deflecting surfaces extending from an opposite side of said bridge in alternating angular relation.
Claim 2
Dependent Claim
76 words
A packing for a mass transfer, direct heat exchange and mixing comprising a plurality of X-shaped profiled layers disposed at the outer longitudinal edges thereof in side-by-side parallel relation with each other, each said layer having a centrally disposed bridge, a first row of deflecting surfaces extending from one side of said bridge in alternating angular relation and a second row of deflecting surfaces extending from an opposite side of said bridge in alternating angular relation.
Claim 3
Dependent Claim
30 words
A packing as set forth in claim 1 wherein each layer has a bridge spaced from said centrally disposed bridge and connected to alternating deflecting elements of said first row.
Claim 4
Dependent Claim
31 words
A packing as set forth in claim 2 wherein each layer has a second bridge spaced from said centrally disposed bridge and connected to alternating deflecting elements of said second row.
Claim 5
Dependent Claim
25 words
A packing a set forth in claim 1 wherein said layers are disposed in contiguous relation to define a plurality of open-ended crossing flow channels.
Claim 6
Dependent Claim
26 words
A packing as set forth in claim 1 which further comprises a plurality of strips connecting adjacent layers together along the ends of alternating deflecting surfaces.
Claim 7
Dependent Claim
99 words
A process of making a multi-layer packing comprising the steps of forming a plurality of flat sheet-like bodies each with a centrally disposed bridge, a first row of discrete deflecting surfaces extending from one side of said bridge and a second row of discrete deflecting surfaces extending from an opposite side of said bridge; bending alternating deflecting surfaces in each said row of each body relative to said respective bridge to define generally X-shaped profiles; and disposing said profiles at the outer longitudinal edges thereof in contiguous side-by-side parallel relation to define a plurality of open-ended crossing flow channels.
Claim 8
Dependent Claim
99 words
A process of making a multi-layer packing comprising the steps of forming a plurality of flat sheet-like bodies each with a centrally disposed bridge, a first row of discrete deflecting surfaces extending from one side of said bridge and a second row of discrete deflecting surfaces extending from an opposite side of said bridge; bending alternating deflecting surfaces in each said row of each body relative to said respective bridge to define generally X-shaped profiles; and disposing said profiles at the outer longitudinal edges thereof in contiguous side-by-side parallel relation to define a plurality of open-ended crossing flow channels.
