Abstract
Abstract This invention relates to an apparatus and method for collecting radon gas and fluids primarily from the periphery of a subterranean enclosure and for discharging the collected fluids and radon gas to the exterior of the enclosure. The apparatus and method create a sealed system around the inside perimeter of the subterranean enclosure. A lower than ambient air pressure created in the system collects the radon gas and fluids therein. The radon gas and fluids separate and the system disposes of them separately.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
152 words
Apparatus for collecting gas and fluids from the periphery of a subterranean enclosure having walls and a floor defining a junction region therebetween and for discharging the collected gas and fluids outside the enclosure, the apparatus comprising: (a) collecting means disposed within the enclosure for collecting gas and fluids from predetermined zones outside the enclosure, said means being impervious to gas and fluids and defining a plurality of conduits in communication with said predetermined zones outside the enclosure, said means being generally disposed at the junction region; (b) means for creating a lower than ambient air pressure in said collecting means so that gas and fluids have a tendency to flow from the predetermined zones outside the enclosure through the conduits and into the collecting means, and for venting the gas outside the enclosure; and (c) means for draining the collected fluid from the collecting means and for disposing of the fluid.
Claim 2
Dependent Claim
152 words
Apparatus for collecting gas and fluids from the periphery of a subterranean enclosure having walls and a floor defining a junction region therebetween and for discharging the collected gas and fluids outside the enclosure, the apparatus comprising: (a) collecting means disposed within the enclosure for collecting gas and fluids from predetermined zones outside the enclosure, said means being impervious to gas and fluids and defining a plurality of conduits in communication with said predetermined zones outside the enclosure, said means being generally disposed at the junction region; (b) means for creating a lower than ambient air pressure in said collecting means so that gas and fluids have a tendency to flow from the predetermined zones outside the enclosure through the conduits and into the collecting means, and for venting the gas outside the enclosure; and (c) means for draining the collected fluid from the collecting means and for disposing of the fluid.
Claim 3
Dependent Claim
30 words
Apparatus as in claim 1 wherein the means for collecting comprises means for forming a gas tight and fluid tight seal with the enclosure between the wall and floor thereof.
Claim 4
Dependent Claim
40 words
A apparatus as in claim 1 wherein the means for collecting further comprises means extending beyond the junction and forming a gas tight and fluid tight seal over an opening in the floor or a wall beyond the junction thereof.
Claim 5
Dependent Claim
25 words
Apparatus as in claim 1 wherein the means for collecting comprises a baseboard having one edge sealed to floor and one edge sealed to wall.
Claim 6
Dependent Claim
21 words
Apparatus as in claim 1 wherein the means for collecting comprises means disposed around substantially the entire interior of the enclosure.
Claim 7
Dependent Claim
13 words
Apparatus as in claim 1 wherein the means for collecting comprises flexible material.
Claim 8
Dependent Claim
33 words
Apparatus as defined in claim 1 wherein the means for venting the gas comprises a gas venting pipe sealed to the collecting means and extending upwardly for removing gas from the collecting means.
Claim 9
Dependent Claim
35 words
Apparatus as defined in claim 1 wherein the means for creating a low air pressure comprises a fan having a suction side connected to the collecting means and an exhaust side connected to the outside.
Claim 10
Dependent Claim
50 words
Apparatus as defined in claim 1 wherein the means for venting the gas and for creating a low air pressure comprises a gas venting pipe sealed to the collecting means and extending upwardly and connected to the suction side of a fan having an exhaust side connected to the outside.
Claim 11
Dependent Claim
39 words
Apparatus as defined in claim 1 wherein the means for draining the collected fluid comprises a gas tight fluid sump and means for connecting the collecting means to the fluid sump for removing the fluid from the collecting means.
Claim 12
Dependent Claim
49 words
Apparatus as defined in claim 10 wherein the sump comprises a well in the floor of the enclosure to collect fluid from at least the collecting means, a lid over said well that is impervious to radon gas, and a gas tight seal between the floor and said lid.
Claim 13
Dependent Claim
18 words
Apparatus as defined in claim 1 wherein the means for draining the collected fluid comprises a fluid pump.
Claim 14
Dependent Claim
67 words
Apparatus of claim 1 wherein the enclosure includes hollow block walls and wherein the collecting means further comprises means sealing the upper portion of the hollows of the block walls, forming chambers therein, and a gas tight conduit connecting the chambers of the block walls to the collecting means so that any gas or fluid in the chambers have a tendency to flow into the collecting means.
Claim 15
Independent Claim
139 words
A method for collecting radon gas and fluids from the periphery of a subterranean enclosure having walls and a floor defining a junction region therebetween and for discharging the collected gas and fluids outside the enclosure, the method comprising the steps of (a) forming a plurality of conduits proximate the junction permitting the flow of gas and fluids from predetermined zones outside the enclosure through the conduits and into the enclosure; (b) creating a lower than ambient air pressure within a collecting means disposed inside the enclosure that is in communication with the formed conduits so that gas and fluids have a tendency to flow into the collecting means from the predetermined zones outside the enclosure; (c) draining the fluid that has flowed into the collecting means; and (d) exhausting the gas that has flowed into the collecting means.
Claim 16
Independent Claim
139 words
A method for collecting radon gas and fluids from the periphery of a subterranean enclosure having walls and a floor defining a junction region therebetween and for discharging the collected gas and fluids outside the enclosure, the method comprising the steps of (a) forming a plurality of conduits proximate the junction permitting the flow of gas and fluids from predetermined zones outside the enclosure through the conduits and into the enclosure; (b) creating a lower than ambient air pressure within a collecting means disposed inside the enclosure that is in communication with the formed conduits so that gas and fluids have a tendency to flow into the collecting means from the predetermined zones outside the enclosure; (c) draining the fluid that has flowed into the collecting means; and (d) exhausting the gas that has flowed into the collecting means.
Claim 17
Dependent Claim
44 words
The method of claim 14 wherein the step of forming a plurality of conduits comprises forming a plurality of apertures extending from predetermined zones outside the enclosure through the junction region and into the enclosure, and interconnecting the formed apertures with a collecting means.
Claim 18
Dependent Claim
47 words
The method of claim 15 wherein the collecting means comprises a baseboard being impervious to gas and fluids, and the step of interconnecting the formed apertures comprises forming a gas tight and fluid tight seal with the baseboard between the floor and walls in the junction region.
Claim 19
Dependent Claim
24 words
The method of claim 14 wherein the step of creating a lower than ambient air pressure comprises drawing a suction on the collecting means.
Claim 20
Dependent Claim
34 words
The method of claim 14 wherein the step of draining the fluid comprises separating the collected fluid from the collected gas by draining the collected fluid from the lower portions of the collecting means.
Claim 21
Dependent Claim
34 words
The method of claim 14 wherein the step of exhausting the gas comprises separating the collected gas from the collected fluid by drawing the collected gas from the upper portions of the collecting means.
Claim 22
Dependent Claim
38 words
The method of claim 14 wherein the enclosure includes hollow block walls and wherein the step of forming a plurality of conduits additionally comprises sealing the upper portion of the hollows of the block walls, forming chambers therein.
