Abstract
Abstract Improved gas liquid contact sheets and contact bodies are disclosed comprising a plurality of parallel and generally vertical corrugated contact sheets, wherein the corrugations form alternating apices in the sheets, the corrugations being disposed at an angle to the horizontal and wherein the corrugations are substantially parallel and adjacent sheets are oriented such that corrugations of one sheet cross the corrugations of an adjacent sheet at intersections of the apices, the improvement comprising positioner pads positioned in apices of the corrugations of the contact sheets, such that at least about eighty percent of the intersections of adjacent sheets contain abutting pairs of the positioner pads. In addition, contact bodies in which adjacent sheet corrugations intersect proximate the edges of the contact sheets are provided.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
107 words
In a gas and liquid contact body, composed of a plurality of parallel and generally vertical corrugated contact sheets, wherein the corrugations form alternating apices in the sheets, the corrugations being disposed at an oblique angle to the horizontal and wherein the corrugations are substantially parallel and adjacent sheets are oriented such that corrugations of one sheet cross the corrugations of an adjacent sheet at intersections of the apices, the improvement comprising generally planar positioner pads positioned in apices of the corrugations of the contact sheets, such that at least about eighty percent of the intersections of adjacent sheets contain abutting, connected pairs of the positioner pads.
Claim 2
Dependent Claim
107 words
In a gas and liquid contact body, composed of a plurality of parallel and generally vertical corrugated contact sheets, wherein the corrugations form alternating apices in the sheets, the corrugations being disposed at an oblique angle to the horizontal and wherein the corrugations are substantially parallel and adjacent sheets are oriented such that corrugations of one sheet cross the corrugations of an adjacent sheet at intersections of the apices, the improvement comprising generally planar positioner pads positioned in apices of the corrugations of the contact sheets, such that at least about eighty percent of the intersections of adjacent sheets contain abutting, connected pairs of the positioner pads.
Claim 3
Dependent Claim
27 words
A contact body according to claim 1 wherein the sheets comprising the contact body are fastened together by adhesive bonds between the pairs of abutting positioner pads.
Claim 4
Dependent Claim
16 words
A contact body according to claim 1 wherein the positioner pads are formed at each intersection.
Claim 5
Dependent Claim
23 words
A contact body according to claim 3 wherein the positioner pads are recessed into the apices of the corrugations of each contact sheet.
Claim 6
Dependent Claim
95 words
In a gas and liquid contact body, composed of a plurality of parallel and generally vertical corrugated contact sheets, wherein the corrugations form alternating apices in the sheets, the corrugations being disposed at an oblique angle to the horizontal and wherein the corrugations are substantially parallel and adjacent sheets are oriented such that corrugations of one sheet cross the corrugations of an adjacent sheet at intersections of the apices, the improvement comprising connected pairs of abutting, generally planar positioner pads formed in the apices of contact sheets at intersections proximate the edges of adjacent sheets.
Claim 7
Dependent Claim
95 words
In a gas and liquid contact body, composed of a plurality of parallel and generally vertical corrugated contact sheets, wherein the corrugations form alternating apices in the sheets, the corrugations being disposed at an oblique angle to the horizontal and wherein the corrugations are substantially parallel and adjacent sheets are oriented such that corrugations of one sheet cross the corrugations of an adjacent sheet at intersections of the apices, the improvement comprising connected pairs of abutting, generally planar positioner pads formed in the apices of contact sheets at intersections proximate the edges of adjacent sheets.
Claim 8
Dependent Claim
28 words
A contact body according to claim 5 wherein at least about eighty percent of the intersections proximate the edges of adjacent sheets contain pairs of abutting positioner pads.
Claim 9
Dependent Claim
27 words
A contact body according to claim 5 wherein the sheets comprising said contact body are fastened together by adhesive bonds between the pairs of abutting positioner pads.
Claim 10
Dependent Claim
27 words
A contact body according to claim 5 further comprising pairs of abutting positioner pads positioned in at least about eighty percent of the intersections of adjacent sheets.
Claim 11
Dependent Claim
15 words
A contact body according to claim 8 wherein positioner pads are formed at each intersection.
Claim 12
Dependent Claim
23 words
