Abstract
Abstract A method and apparatus for protecting human beings from the combined aftereffects of a nuclear explosion, namely, penetrating radiation and the settling of carbon dioxide in low areas. A warning barrier of rope or cord with newspaper suspended therefrom is erected in the upper level of a building to delineate a safe area beyond the penetration distances of alpha and beta radiation. A combustion means having an exposed flame is provided within the safe area for insertion through an aperture in the floor into the basement of the building where refuge is to be sought against more penetrating gamma radiation. The flame is observed through a second aperture to check and verify the quality of the atmosphere therein before entering the basement.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
266 words
Apparatus for determining a lack of oxygen within a building having a floor and upper and lower levels above and below said floor respectively and a certain atmosphere within each level comprising a portable combustion means for testing an atmosphere having a flame exposed to said atmosphere; said combustion means including an elongated extension projecting therefrom bent into a J-shape, having a fluid passageway therethrough, and means for passing a combustible gas through said passageway, said J-shaped extension including a vertically upwardly extending opening for emitting said combustible gas upwardly to provide an upwardly extending flame visible from above; and aperture means in said floor for reciprocally raising and lowering said extension in said floor such that said combustion means may be lowered into the atmosphere of said lower level to test the oxygen quality of that atmosphere, said aperture means including a portion allowing ignition of said combustible gas by raising of the portion of said extension including said opening through said floor for said ignition of said combustible gas at said opening whereby, when said extension is lowered into said lower level, said flame will be extinguished if there is sufficient lack of oxygen in said atmosphere of said lower level; said aperture means including a first aperture in which said extension is mounted for reciprocal raising and lowering and a second aperture comprising said portion of said aperture means through which the portion of said extension including said opening is passed for ignition of said flame and through which said flame is observed as said extension is lowered into said lower level atmosphere.
Claim 2
Dependent Claim
266 words
Apparatus for determining a lack of oxygen within a building having a floor and upper and lower levels above and below said floor respectively and a certain atmosphere within each level comprising a portable combustion means for testing an atmosphere having a flame exposed to said atmosphere; said combustion means including an elongated extension projecting therefrom bent into a J-shape, having a fluid passageway therethrough, and means for passing a combustible gas through said passageway, said J-shaped extension including a vertically upwardly extending opening for emitting said combustible gas upwardly to provide an upwardly extending flame visible from above; and aperture means in said floor for reciprocally raising and lowering said extension in said floor such that said combustion means may be lowered into the atmosphere of said lower level to test the oxygen quality of that atmosphere, said aperture means including a portion allowing ignition of said combustible gas by raising of the portion of said extension including said opening through said floor for said ignition of said combustible gas at said opening whereby, when said extension is lowered into said lower level, said flame will be extinguished if there is sufficient lack of oxygen in said atmosphere of said lower level; said aperture means including a first aperture in which said extension is mounted for reciprocal raising and lowering and a second aperture comprising said portion of said aperture means through which the portion of said extension including said opening is passed for ignition of said flame and through which said flame is observed as said extension is lowered into said lower level atmosphere.
Claim 3
Dependent Claim
41 words
Apparatus as described in claim 1 wherein pipes are mounted in said apertures in said floor, said pipes comprising fireproof material and including fireproof covers on the upper ends thereof, said covers each including an aperture and a closure means therein.
Claim 4
Dependent Claim
20 words
Apparatus as described in claim 2 wherein said floor is between a basement and first floor level of said building.
Claim 5
Dependent Claim
145 words
Apparatus for determining the lack of oxygen in the lower level of a building having at least an upper and lower level and a floor therebetween; said apparatus comprising two apertures formed in said floor, and means for determining a lack of oxygen in an atmosphere; one of said apertures being of sufficient size to allow the oxygen sufficiency determining means to be raised and lowered therethrough into and out of the atmosphere of said lower level; said oxygen sufficiency determining means including upwardly extending means for insertion into said upper level from said lower level through the other of said apertures to initiate operation of said oxygen sufficiently determining means, said other aperture also being sufficiently large to allow the visual observation of said oxygen sufficiency determining means when lowered into said lower level atmosphere for visual determination of the quality of said atmosphere.
Claim 6
Dependent Claim
145 words
Apparatus for determining the lack of oxygen in the lower level of a building having at least an upper and lower level and a floor therebetween; said apparatus comprising two apertures formed in said floor, and means for determining a lack of oxygen in an atmosphere; one of said apertures being of sufficient size to allow the oxygen sufficiency determining means to be raised and lowered therethrough into and out of the atmosphere of said lower level; said oxygen sufficiency determining means including upwardly extending means for insertion into said upper level from said lower level through the other of said apertures to initiate operation of said oxygen sufficiently determining means, said other aperture also being sufficiently large to allow the visual observation of said oxygen sufficiency determining means when lowered into said lower level atmosphere for visual determination of the quality of said atmosphere.
Claim 7
Dependent Claim
38 words
The apparatus of claim 4 wherein said oxygen sufficiency determining means comprises a combustion means including an open flame; the amount of oxygen in said lower level atmosphere being determined by observing said flame through said other aperture.
Claim 8
Dependent Claim
24 words
The apparatus of claim 5 wherein said apertures are immediately adjacent one another, whereby said combustion means can be ignited through said other aperture.
