Abstract
Abstract A bed for the treatment of fluids comprising a plurality of packing units. Each packing unit has a plurality of fins disposed around an axis lying substantially in the plane of each of the fins. The fins are held in a spaced relationship to one another by at least one generally annular reinforcing member between each angularly adjacent pair of fins in a plane substantially perpendicular to the axis. The outward facing edges of the fins are serrated.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
125 words
A bed for the treatment of fluids comprising a plurality of packing units characterized in that each packing unit consists essentially of a plurality of fins disposed around an axis lying substantially in the plane of each of the fins, and at least one generally part annular reinforcing member between each angularly adjacent pair of fins in a plane substantially perpendicular to the axis, holding said fins in spaced relationship to one another, the outward-facing edges of the fins being serrated, the packing units being so shaped that they take up a random configuration in the bed, with contact between adjacent units being predominantly along the edges of the fins and the reinforcing members, whereby fluid applied to the bed is distributed substantially evenly therethrough.
Claim 2
Dependent Claim
125 words
A bed for the treatment of fluids comprising a plurality of packing units characterized in that each packing unit consists essentially of a plurality of fins disposed around an axis lying substantially in the plane of each of the fins, and at least one generally part annular reinforcing member between each angularly adjacent pair of fins in a plane substantially perpendicular to the axis, holding said fins in spaced relationship to one another, the outward-facing edges of the fins being serrated, the packing units being so shaped that they take up a random configuration in the bed, with contact between adjacent units being predominantly along the edges of the fins and the reinforcing members, whereby fluid applied to the bed is distributed substantially evenly therethrough.
Claim 3
Dependent Claim
17 words
A bed as claimed in claim 1, wherein the packing unit has from 3 to 12 fins.
Claim 4
Dependent Claim
21 words
A bed as claimed in claim 1, wherein the part angular reinforcing members together form one or more generally angular plates.
Claim 5
Dependent Claim
21 words
A bed as claimed in claim 1, wherein the outer edges of the reinforcing members of each packing unit are serrated.
Claim 6
Dependent Claim
20 words
A bed as claimed in claim 1, wherein the axial length of each unit is from 3 to 18 cms.
Claim 7
Dependent Claim
35 words
A bed as claimed in claim 1, wherein there is one reinforcing member between each adjacent pair of fins, all the reinforcing members being in the same plane and forming a generally annualr reinforcing plate.
Claim 8
Dependent Claim
140 words
A bed for the treatment of fluids comprising a plurality of packing units characterized in that each packing unit consists essentially of a hollow tube having a longitudinal axis, a plurality of fins radiating from the outer surface of the tube substantially in the same plane as the axis of the tube, and at least one generally part annular reinforcing member between each angularly adjacent pair of fins in a plane substantially perpendicular to the axis of the tube, holding said fins in spaced relationship to one another, the outward-facing edges of the fins being serrated, the packing units being so shaped that they take up a random configuration in the bed, with contact between adjacent units being predominantly along the edges of the fins and the reinforcing members, whereby fluid applied to the bed is distributed substantially evenly therethrough.
Claim 9
Dependent Claim
140 words
A bed for the treatment of fluids comprising a plurality of packing units characterized in that each packing unit consists essentially of a hollow tube having a longitudinal axis, a plurality of fins radiating from the outer surface of the tube substantially in the same plane as the axis of the tube, and at least one generally part annular reinforcing member between each angularly adjacent pair of fins in a plane substantially perpendicular to the axis of the tube, holding said fins in spaced relationship to one another, the outward-facing edges of the fins being serrated, the packing units being so shaped that they take up a random configuration in the bed, with contact between adjacent units being predominantly along the edges of the fins and the reinforcing members, whereby fluid applied to the bed is distributed substantially evenly therethrough.
Claim 10
Dependent Claim
28 words

Claim 11
Dependent Claim
17 words
A bed as claimed in claim 7, wherein the packing unit has from 3 to 12 fins.
Claim 12
Dependent Claim
21 words

Claim 13
Dependent Claim
21 words

Claim 14
Dependent Claim
20 words
A bed as claimed in claim 7, wherein the axial length of each unit is from 3 to 18 cms.
