Abstract
Abstract A hyperboloidal cooling tower has a central post from which is suspended an upper horizontal ring centered on the post. A network of cables strung from the upper ring define a generally hyperboloidal surface, with the cables criss-crossing and the intersections clamped together with clips. A plurality of corrugated aluminum plates is secured inside the array of cables at the clips with the corrugations of the plates extending upwardly. The corrugations of each plate are spread to a greater and lesser extent at different regions along the plate together so that these plates may form a uniform three-dimensional shape. Each of the plates is secured at its central region fixedly to at least one clip and otherwise secured to the clips via stringers which can slide on these clips so as to allow thermal expansion of the plates relative to the cable network and relative to one another.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
165 words
In a cooling tower having an upwardly open chimney for inducing a flow of air therethrough and provided with means for supplying a cooling liquid thereto, a structure forming said chimney, said structure comprising: an upright post defining an axis; a horizontal upper ring suspended from said post and centered on said axis; an array of cables hanging from said ring and defining thereunder a generally hyperboloidal surface centered on said axis, said cables crossing one another at intersections; a plurality of clips each secured to said cables at a respective intersection; a plurality of metal plates having vertical corrugations of generally trapezoidal section; and respective rigid stringers each secured to a plurality of said clips and extending across the width of each of said plates and fastened thereto, said stringers securing each plate to said array by said clips so that each plate lies on said surface with its corrugations horizontally spread to greater and lesser extent at different vertical regions along the plate.
Claim 2
Dependent Claim
165 words
In a cooling tower having an upwardly open chimney for inducing a flow of air therethrough and provided with means for supplying a cooling liquid thereto, a structure forming said chimney, said structure comprising: an upright post defining an axis; a horizontal upper ring suspended from said post and centered on said axis; an array of cables hanging from said ring and defining thereunder a generally hyperboloidal surface centered on said axis, said cables crossing one another at intersections; a plurality of clips each secured to said cables at a respective intersection; a plurality of metal plates having vertical corrugations of generally trapezoidal section; and respective rigid stringers each secured to a plurality of said clips and extending across the width of each of said plates and fastened thereto, said stringers securing each plate to said array by said clips so that each plate lies on said surface with its corrugations horizontally spread to greater and lesser extent at different vertical regions along the plate.
Claim 3
Dependent Claim
179 words
In a cooling tower having an upwardly open chimney for inducing a flow of air therethrough and provided with means for supplying a cooling liquid thereto, a structure forming said chimney, said structure comprising: an upright post defining an axis; a horizontal upper ring suspended from said post and centered on said axis; an array of cables hanging from said ring and defining thereunder a generally hyperboloidal surface centered on said axis, said cables crossing one another at intersections; a plurality of clips each secured to said cables at a respective intersection; and a plurality of metal plates having vertical corrugations, each plate being secured to said array by said clips so as to lie on said surface with its corrugations horizontally spread to greater and lesser extents at different vertical regions along the plate, each plate having and being mounted on a plurality of rigid stringers each secured to said array at a plurality of such clips, at least some of said clips being each provided with an H-shaped block, the respective stringers being slidable in said blocks.
