Abstract
Abstract An improved packing body for use in packed columns which is formed of a longitudinally extending central core from which a plurality of web members generally radially extend. The web members are in substantially axial alignment with the core and are formed of a plurality of open cellular units. The packing body provides a maximal amount of wettable surface area and drip formation points with a minimum of obstruction to fluid flow within a packed column.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
92 words
An improved high efficiency, high performance packing body for use in packed columns, towers or the like, said packing body comprising: a longitudinally extending central core; a plurality of longitudinally disposed generally concentric arcuate members radially extending from said central core and generally uniformly spaced apart from one another; and a plurality of generally radially extending struts generally uniformly spaced apart from one another and interconnecting adjacent pairs of said arcuate members to define a plurality of generally uniformly spaced open cellular units within a packing body having a generally symmetrical configuration.
Claim 2
Dependent Claim
92 words
An improved high efficiency, high performance packing body for use in packed columns, towers or the like, said packing body comprising: a longitudinally extending central core; a plurality of longitudinally disposed generally concentric arcuate members radially extending from said central core and generally uniformly spaced apart from one another; and a plurality of generally radially extending struts generally uniformly spaced apart from one another and interconnecting adjacent pairs of said arcuate members to define a plurality of generally uniformly spaced open cellular units within a packing body having a generally symmetrical configuration.
Claim 3
Dependent Claim
20 words
The improved packing body of claim 1, further comprising: means rib for interconnecting at least some of said arcuate members.
Claim 4
Dependent Claim
29 words
The improved packing body of claim 2, wherein said means for interconnecting comprises a plurality of rib members spaced remotely from said central core and interconnecting adjacent arcuate members.
Claim 5
Dependent Claim
27 words
The improved packing body of claim 1 wherein each of said arcuate members is smoothly curving thereby defining a packing body having a generally spherical outer configuration.
Claim 6
Dependent Claim
26 words
The improved packing body of claim 1 wherein each of said arcuate members is faceted thereby defining a packing body having a generally polygonal outer configuration.
Claim 7
Dependent Claim
13 words
The improved packing body of claim 1 wherien said central core is solid.
Claim 8
Dependent Claim
13 words
The improved packing body of claim 1 wherein said central core is hollow.
Claim 9
Dependent Claim
22 words
The improved packing body of claim 1 wherein at least some of said strut members are bisected to provide additional drip points.
Claim 10
Dependent Claim
27 words
The improved packing body of claim 1 further comprising a plurality of projecting fingers extending from at least some of said arcuate members or radially extending struts.
Claim 11
Dependent Claim
22 words
The improved packing body of claim 1 wherein at least one of said arcuate members is cut to provide additional drip points.
Claim 12
Dependent Claim
173 words
An improved high efficiency, high performance, packing body for use in packed columns, towers or the like, said packing body comprising: a longitudinally extending central core; a plurality of web members generally radially extending from said core in substantially axial alignment therewith, each of said web members formed of a plurality of generally concentric arcuate members generally uniformly spaced apart from one another along the radial extent of each of said web members, adjacent pairs of said arcuate members being interconnected by at least one generally radially extending strut to define a plurality of open cellular units generally uniformly distributed along the radial extent of each of said web members; and means for interconnecting at least some of said web members, said means for interconnecting comprising a plurality of rib members spaced remotely from said central core in communicative engagement between at least some of said web members, whereby said packing body is provided with a plurality of open cellular units generally uniformly distributed from its central core throughout its generally symmetrical configuration.
Claim 13
Dependent Claim
173 words
An improved high efficiency, high performance, packing body for use in packed columns, towers or the like, said packing body comprising: a longitudinally extending central core; a plurality of web members generally radially extending from said core in substantially axial alignment therewith, each of said web members formed of a plurality of generally concentric arcuate members generally uniformly spaced apart from one another along the radial extent of each of said web members, adjacent pairs of said arcuate members being interconnected by at least one generally radially extending strut to define a plurality of open cellular units generally uniformly distributed along the radial extent of each of said web members; and means for interconnecting at least some of said web members, said means for interconnecting comprising a plurality of rib members spaced remotely from said central core in communicative engagement between at least some of said web members, whereby said packing body is provided with a plurality of open cellular units generally uniformly distributed from its central core throughout its generally symmetrical configuration.
Claim 14
Dependent Claim
27 words
The improved packing body of claim 11 wherein each of said arcuate members is smoothly curving thereby defining a packing body having a generally spherical outer configuration.
Claim 15
Dependent Claim
26 words
The improved packing body of claim 11 wherein each of said arcuate members is faceted thereby defining a packing body having a generally polygonal outer configuration.
