Abstract
Abstract A removable condensate collector for elevated water storage facilities includes a membrane attached to the walls of such elevated water storage facility and positioned to prevent condensate from falling onto structures located at or near the bottom of the facility from a water storage container located at or near the top of the facility. The membrane can be frusto-conical in shape with the apex thereof located above or below the base, or can be horizontally disposed within the facility.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
162 words
An improvement in an elevated water storage facility including a water storage tank supported on top of an enclosed column and a partition means extending across the column dividing the enclosed column into an air space above the partition and a work area for offices, warehouses, and the like located beneath the partition with elements located in the work area which can be damaged by condensate falling thereonto from the tank, the improvement comprising collecting means for collecting condensed water vapor which drips from the underside of said tank, the collecting means including: attaching means mounted on a wall of the enclosed column above the partition; a membrane attached to said attaching means and mounted inside the column at a location between the tank and the partition for collecting any condensate falling from the tank prior to that condensate falling onto the partition; and drain means fluidly connected with said membrane for conducting condensate collected by said membrane away from said membrane.
Claim 2
Dependent Claim
162 words
An improvement in an elevated water storage facility including a water storage tank supported on top of an enclosed column and a partition means extending across the column dividing the enclosed column into an air space above the partition and a work area for offices, warehouses, and the like located beneath the partition with elements located in the work area which can be damaged by condensate falling thereonto from the tank, the improvement comprising collecting means for collecting condensed water vapor which drips from the underside of said tank, the collecting means including: attaching means mounted on a wall of the enclosed column above the partition; a membrane attached to said attaching means and mounted inside the column at a location between the tank and the partition for collecting any condensate falling from the tank prior to that condensate falling onto the partition; and drain means fluidly connected with said membrane for conducting condensate collected by said membrane away from said membrane.
Claim 3
Dependent Claim
58 words
The improvement defined in claim 1 wherein said attaching means includes a mounting base attached to the column wall and having a membrane attaching face spaced radially inward from the column wall, said membrane being attached to said attaching face so that said membrane is attached to said attaching means at a location spaced from the column wall.
Claim 4
Dependent Claim
17 words
The improvement defined in claim 2 wherein said mounting base includes means for stiffening the column wall.
Claim 5
Dependent Claim
16 words
The improvement defined in claim 1 further including an erection lifting lug mounted on said membrane.
Claim 6
Dependent Claim
33 words
The improvement defined in claim 1 wherein said drain means further includes a sump located centrally of said membrane and a drain conduit located beneath said membrane and fluidly connected to said sump.
Claim 7
Dependent Claim
31 words
The improvement defined in claim 5 wherein said drain conduit extends radially outward from said sump toward the column wall and contacts that column wall at a location above the partition.
Claim 8
Dependent Claim
23 words
The improvement defined in claim 6 wherein said drain conduit is attached to the column wall and extends downwardly along that column wall.
Claim 9
Dependent Claim
15 words
The improvement defined in claim 7 wherein said drain conduit extends through the column wall.
Claim 10
Dependent Claim
150 words
An improvement in an elevated water storage facility including a water storage tank supported on top of an enclosed column, the column being divided into an air space and a work area for offices, warehouses, and the like with elements located in the work area which can be damaged by condensate falling thereonto from the tank, the improvement comprising collecting means for collecting condensed water vapor which drips from the underside of said tank, the collecting means including: attaching means mounted on a wall of the enclosed column above the work area; a membrane attached to said attaching means and mounted inside the column at a location between the tank and the work area for collecting any condensate falling from the tank prior to that condensate falling into the work area; and drain means fluidly connected with said membrane for conducting condensate collected by said membrane away from said membrane.
Claim 11
Dependent Claim
