Abstract

Abstract A cooling tower with a non-self-supporting envelope which is supported by a net of cables and by pulling elements extending from a portion of a supporting post which portion protrudes upwardly beyond the outlet opening of the cooling tower mantle, in which annular means surround the outlet opening of the mantle and are connected to the supporting post by elements extending in a spoke-like manner from the supporting post and at least partially subjected to pull only.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 217 words
A cooling tower having an exit opening and comprising in combination: (a) a foundation and a post mounted thereon, (b) a rigid upper spacer ring below the top of said post surrounding the exit opening, (c) cable means under tension on said post projecting downwardly and over the exit opening and having said rigid upper spacer ring suspended thereby, (d) one smaller spacer ring arranged below said upper spacer ring, (e) cables guided from fastening locations on said upper spacer ring to fastening locations on said lower spacer ring and to fastening locations on said foundation spaced outwardly from said post a greater distance than said lower spacer ring, (f) whereby the fastening locations on said lower spacer ring have a smaller distance from said post than the fastening locations on said upper spacer ring and than the fastening locations on said foundation, (g) radial cable-type connection means provided between said spacer rings and said post that are capable of being loaded only under tension exclusively and then are preloaded under tension only for resistance against wind forces, (h) a non-self-supporting mantle laced in at said lower spacer ring particularly to withstand wind forces as supported by said cables and extending downwardly from said upper spacer ring to leave an opening through said upper and lower rings.
Claim 2
Dependent Claim 217 words
A cooling tower having an exit opening and comprising in combination: (a) a foundation and a post mounted thereon, (b) a rigid upper spacer ring below the top of said post surrounding the exit opening, (c) cable means under tension on said post projecting downwardly and over the exit opening and having said rigid upper spacer ring suspended thereby, (d) one smaller spacer ring arranged below said upper spacer ring, (e) cables guided from fastening locations on said upper spacer ring to fastening locations on said lower spacer ring and to fastening locations on said foundation spaced outwardly from said post a greater distance than said lower spacer ring, (f) whereby the fastening locations on said lower spacer ring have a smaller distance from said post than the fastening locations on said upper spacer ring and than the fastening locations on said foundation, (g) radial cable-type connection means provided between said spacer rings and said post that are capable of being loaded only under tension exclusively and then are preloaded under tension only for resistance against wind forces, (h) a non-self-supporting mantle laced in at said lower spacer ring particularly to withstand wind forces as supported by said cables and extending downwardly from said upper spacer ring to leave an opening through said upper and lower rings.
Claim 3
Dependent Claim 23 words
A cooling tower in combination according to claim 1 in which said lower spacer ring is capable of being loaded only under tension.
Claim 4
Dependent Claim 277 words
A cooling tower having an exit opening and comprising in combination: (j) a foundation and a post mounted thereon, (k) a rigid upper spacer ring below the top of said post surrounding the exit opening, (l) cable means under tension on said post projecting downwardly and over the exit opening and having said rigid upper spacer ring suspended thereby, (m) at least two lower spacer rings arranged below aaid upper spacer ring and one below the other, said other ring adjacent said upper ring being smaller than the upper spacer ring, (n) cables guided from fastening locations on said upper spacer ring to fastening locations on said lower spacer rings and to fastening locations on said foundation spaced outwardly from said post a greater distance than said other of said lower rings and said upper ring, (o) whereby the fastening locations on that lower spacer ring which is nearest to said upper spacer ring have a smaller distance from said post than the fastening locations on said upper spacer ring, and (p) whereby the fastening locations on the lowermost of said lower spacer rings have a smaller distance from said post than the fastening locations on said foundation, (q) radial cable-type connection means provided between said spacer rings and said post are capable of being loaded only under tension and are preloaded exclusively under tension rather than also being subjected to pressure, kinking or bending load for resistance against wind forces, (r) a non-self-supporting mantle laced in at said lower spacer rings particularly to withstand wind forces as supported by said cables and extending downwardly from said upper spacer ring to leave an opening through said rings.
Claim 5
Dependent Claim 277 words
A cooling tower having an exit opening and comprising in combination: (j) a foundation and a post mounted thereon, (k) a rigid upper spacer ring below the top of said post surrounding the exit opening, (l) cable means under tension on said post projecting downwardly and over the exit opening and having said rigid upper spacer ring suspended thereby, (m) at least two lower spacer rings arranged below aaid upper spacer ring and one below the other, said other ring adjacent said upper ring being smaller than the upper spacer ring, (n) cables guided from fastening locations on said upper spacer ring to fastening locations on said lower spacer rings and to fastening locations on said foundation spaced outwardly from said post a greater distance than said other of said lower rings and said upper ring, (o) whereby the fastening locations on that lower spacer ring which is nearest to said upper spacer ring have a smaller distance from said post than the fastening locations on said upper spacer ring, and (p) whereby the fastening locations on the lowermost of said lower spacer rings have a smaller distance from said post than the fastening locations on said foundation, (q) radial cable-type connection means provided between said spacer rings and said post are capable of being loaded only under tension and are preloaded exclusively under tension rather than also being subjected to pressure, kinking or bending load for resistance against wind forces, (r) a non-self-supporting mantle laced in at said lower spacer rings particularly to withstand wind forces as supported by said cables and extending downwardly from said upper spacer ring to leave an opening through said rings.
Claim 6
Dependent Claim 23 words
A cooling tower in combination according to claim 3 in which said lower spacer rings are capable of being loaded only under tension.
