Abstract

Abstract A system for protecting an enclosed space from the effects of above- and below-normal temperatures comprises means defining an enclosed space including at least one relatively large opening, a screen-like cover over said opening containing numerous smaller openings which have been closed over with a water-removable composition comprising a water soluble, heat transfer resistant organic polymeric coating.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 137 words
A system for protecting an enclosed space from the effects of temperature extremes while such extremes prevail and for removing such protection after such extremes pass comprising: means defining an enclosed space including at least one opening large enough to permit temperature losses from the interior whereby above- and below-normal temperatures are produced; a screen-like cover over said opening comprising a material containing a multiplicity of smaller openings; and a heat transfer resistant, water-removable coating on said cover in an amount at least sufficient to form a continuous bridge over the openings therein whereby the enclosed space is protected from the effects of temperature extremes while such coating bridges said openings and the interior of said enclosure is vented to the exterior by removing said bridging coating from said openings with water after said temperature extreme passes.
Claim 2
Independent Claim 137 words
A system for protecting an enclosed space from the effects of temperature extremes while such extremes prevail and for removing such protection after such extremes pass comprising: means defining an enclosed space including at least one opening large enough to permit temperature losses from the interior whereby above- and below-normal temperatures are produced; a screen-like cover over said opening comprising a material containing a multiplicity of smaller openings; and a heat transfer resistant, water-removable coating on said cover in an amount at least sufficient to form a continuous bridge over the openings therein whereby the enclosed space is protected from the effects of temperature extremes while such coating bridges said openings and the interior of said enclosure is vented to the exterior by removing said bridging coating from said openings with water after said temperature extreme passes.
Claim 3
Dependent Claim 23 words
A system as defined in claim 1 wherein said enclosed space is a house for human habitation and said opening comprises a door.
Claim 4
Dependent Claim 17 words
A system as defined in claim 2 which also includes at least one window as said opening.
Claim 5
Dependent Claim 17 words
A system as defined in claim 1 wherein said enclosed space is a porch on a house.
Claim 6
Dependent Claim 41 words
A system as defined in claim 1 wherein said opening is covered at least in part by an imperforate sheetlike pane and said screen-like cover is spaced apart from said imperforate pane so as to form a dead air space therebetween.
Claim 7
Dependent Claim 14 words
A system as defined in claim 5 wherein said imperforate sheet-like pane comprises glass.
Claim 8
Dependent Claim 18 words
A system as defined in claim 1 wherein said coating is transluscent to permit light to pass therethrough
Claim 9
Dependent Claim 31 words
A system as defined in claim 1 wherein said coating is the product of in situ evaporation of water from an aqueous medium containing a natural or synthetic organic polymeric substance.
Claim 10
Dependent Claim 15 words
A system as defined in claim 8 wherein said organic polymeric substance is methyl cellulose.
Claim 11
Dependent Claim 15 words
A system as defined in claim 8 wherein said organic polymeric substance is poly(vinyl alcohol).
