Abstract

Abstract A contact body element for use in forming fill or decking for a gas and liquid contact apparatus, such as a cooling tower; a method for use of the contact body element in such an apparatus, and an improved fastening member for maintaining the contact body elements in desired assembled operative orientation in the apparatus. The novel fill comprises a thin sheet of fibrous or plastic material. The sheet may be corrugated and the corrugations may run askew to a longitudinal axis of the sheet. A reinforcing ply is secured to the sheet, said ply formed by folding a portion of the sheet over on itself and/or by securing a separate strip to the sheet. The reinforcing ply is positioned along the sheet edge. In use, according to the novel method, these corrugated reinforced sheets have sufficient strength and rigidity, so that they may be shipped in a nested stacked package to a point of desired use, where they are assembled in a cooling tower by arranging the fill sheets to run with the corrugations spacing the sheets to provide for a plurality of spaced fluid flow channels. Fastening means may be provided for maintaining the assembled fill in desired operative orientation. The fasteners comprise an elongate skewer like member formed of sheet metal with a separable point at one end and tail pieces at the other end subject to being bent out of the plane of the skewer, after the skewer is inserted through the assembled fill sheets.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 102 words
A contact body element for use in forming the fill of a gas and liquid contact apparatus to produce interaction between a gas and liquid flowing through the apparatus, said contact body element comprising: a corrugated sheet member having a plurality of linearly extending corrugations running across said sheet askew to a longitudinal axis of said sheet; and a longitudinally extending edge of said sheet member folded over on a longitudinally extending edge of said corrugated sheet member to provide a strip of sheet material secured in overlapping relationship to the surface of said corrugated sheet member to form a reinforcing ply.
Claim 2
Dependent Claim 102 words
A contact body element for use in forming the fill of a gas and liquid contact apparatus to produce interaction between a gas and liquid flowing through the apparatus, said contact body element comprising: a corrugated sheet member having a plurality of linearly extending corrugations running across said sheet askew to a longitudinal axis of said sheet; and a longitudinally extending edge of said sheet member folded over on a longitudinally extending edge of said corrugated sheet member to provide a strip of sheet material secured in overlapping relationship to the surface of said corrugated sheet member to form a reinforcing ply.
Claim 3
Dependent Claim 41 words
A contact body element as in claim 1 in which said sheet member has a plurality of spaced corrugations extending thereacross, said reinforcing ply extending along an edge of said sheet member in a direction across the direction of said corrugations.
Claim 4
Dependent Claim 33 words
A contact body element as in claim 2 in which said contact body element is formed with a taper contour in longitudinal cross-section through the corrugation at the sheet edge and reinforcing ply.
Claim 5
Dependent Claim 30 words
A contact body comprising a plurality of contact body elements as in claim 1 secured to each other by means spacing said elements to form flow channels between said elements.
Claim 6
Dependent Claim 24 words
A contact body as in claim 4, in which said elements are at least in part corrugated to form flow channels between said elements.
Claim 7
Dependent Claim 60 words
A contact body as in claim 4 in which said contact body elements are secured to each other by means of a fastening member extending through a plurality of said elements, said fastening member comprising: an elongate spike-like skewer having a point on one end thereof; and ears on the tail end of said spike-like skewer opposite the point thereof.
Claim 8
Dependent Claim 48 words
A contact body as in claim 6 in which said fastening member comprises: an elongate sheet material skewer formed by a strip of sheet material bent along a longitudinal axis of said strip; and split along said longitudinal axis at said point to form ears at said point.
Claim 9
Dependent Claim 28 words
A contact body element as in claim 1 in which said edge of said sheet member is folded more than once to provide a multiple layer reinforcing ply.
Claim 10
Dependent Claim 27 words
A contact body element as in claim 1 in which an auxiliary strip of sheet metal is sandwiched between said folded over edge and said sheet member.
