Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
100 words
A modular packing element for mass and heat exchange, adapted for coupling into an assembly having a vertical axis and a generally prismatic or rectangular shape in cross-section with open bases, comprising a continuous side wall element formed of rolled sheet material having both surfaces formed with an array of elongated, thin protrusions in form of needles, cones, spikes, or the like, of various lengths, extending both inwardly and outwardly of the wall element and located radially uniformly around a central portion of the side wall, and located at generally equal distances from the longer edges of the sheet-like material.
Claim 2
Dependent Claim
100 words
A modular packing element for mass and heat exchange, adapted for coupling into an assembly having a vertical axis and a generally prismatic or rectangular shape in cross-section with open bases, comprising a continuous side wall element formed of rolled sheet material having both surfaces formed with an array of elongated, thin protrusions in form of needles, cones, spikes, or the like, of various lengths, extending both inwardly and outwardly of the wall element and located radially uniformly around a central portion of the side wall, and located at generally equal distances from the longer edges of the sheet-like material.
Claim 3
Dependent Claim
38 words
The modular packing element according to claim 1, wherein the outer protrusions of the side wall are located in groups, with vertical axes of symmetry equally spaced one from another and from the edges of the wall material.
Claim 4
Dependent Claim
32 words
An assembly of elements according to claim 1, wherein the outer protrusions substantially fill the spaces located between the side wall of each adjacent element and the outer perimeter of the assembly.
Claim 5
Dependent Claim
45 words
The modular element according to claim 1, wherein the edge of the side wall around one base has raised portions and at the base edge a plurality of sockets for connecting with corresponding raised portions of other elements in order to form an interlocked assembly.
Claim 6
Dependent Claim
37 words
The modular element according to claim 1, wherein the side wall is formed into cylindrical shape, the inward protrusions substantially filling the inside thereof, and the outward protrusions forming a generally cubic outer profile for the element.
