Abstract
Abstract A coated glass glazing system is presented including a transparent glass substrate having one surface coated with a radiation absorptive film which is overcoated with a radiation reflective film by a technique which renders the radiation reflective film radiation absorptive at the surface contacting the radiating absorptive film. The coated glass system is used as glazing for storm windows which are adapted to be reversible so that the radiation reflective surface may be exposed to the outside of the dwelling during the warm seasons to prevent excessive solar radiation from entering a dwelling and reversed during cold seasons to absorb solar radiation and utilize it to aid in keeping the dwelling interior warm.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
82 words
A glazing assembly, comprising: a thermally insulating glass substrate; a radiation absorption film comprised of a thermally conductive material affixed to one surface of said glass substrate; and a radiation reflective film comprised of a thermally conductive material with one surface exposed to the atmosphere and an opposite surface secured to the surface of said radiation absorption film opposite said glass substrate whereby radiation absorbed by said radiation absorption film as heat is conducted to said radiation reflective film and radiated therefrom.
Claim 2
Dependent Claim
82 words
A glazing assembly, comprising: a thermally insulating glass substrate; a radiation absorption film comprised of a thermally conductive material affixed to one surface of said glass substrate; and a radiation reflective film comprised of a thermally conductive material with one surface exposed to the atmosphere and an opposite surface secured to the surface of said radiation absorption film opposite said glass substrate whereby radiation absorbed by said radiation absorption film as heat is conducted to said radiation reflective film and radiated therefrom.
Claim 3
Dependent Claim
19 words
An apparatus as defined in claim 1 wherein said radiation is in a range between 400 and 1400 angstroms.
Claim 4
Dependent Claim
23 words
An apparatus as defined in claim 1 wherein said radiation absorptive film is black nickel and said radiation reflective film is bright nickel.
Claim 5
Dependent Claim
31 words
An apparatus as defined in claim 1 wherein said radiation absorptive film is applied to said glass substrate by an electrolysis deposition method and said radiation reflective film is electroplated thereon.
Claim 6
Dependent Claim
62 words
An apparatus as defined in claim 1 further comprising: a window frame supporting the edges of said glass substrate; first and second protrusions extending outwardly from said window frame at opposite sides thereof adjacent to a common perpendicular side; and first and second spring biased protrusions projecting from said opposite sides of said window frame and adjacent to a second perpendicular side.
Claim 7
Dependent Claim
37 words
An apparatus as defined in claim 5 wherein first and second recesses are provided in said opposite sides of said window frame dimensioned to permit said spring biased protrusions to be urged within said window frame boundaries.
Claim 8
Dependent Claim
46 words
An apparatus as defined in claim 6 further comprising a rectangular framework incorporating an inner channel dimensioned to receive said protrusions and spring biased protrusions for slidably supporting said glass substrate so that said radiation reflective film may selectively be placed to face in or out.
Claim 9
Dependent Claim
34 words
An apparatus as defined in claim 7 wherein said channel includes a plurality of recesses adapted to cooperate with said spring biased protrusions for securing said window frame in various positions along said channels.
Claim 10
Dependent Claim
49 words
An apparatus as defined in claim 1 wherein said glass substrate is contained within a window frame adapted to permit the removable installation within a dwelling so that said radiation reflective film may be alternated between the exterior and interior of said dwelling as a function of climatic seasons.
