Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
68 words
A thermal insulating glazing unit comprising a plurality of sealed and evacuated glass tubes having respective longitudinal axes, the tubes being covered on their respective inner sides by a light-transmitting infrared-reflecting coating and arranged in a layer in contact with each other with their longitudinal axes parallel, whereby light may be transmitted through the unit transverse to the longitudinal axes of the tubes while infrared energy is reflected.
Claim 2
Dependent Claim
68 words
A thermal insulating glazing unit comprising a plurality of sealed and evacuated glass tubes having respective longitudinal axes, the tubes being covered on their respective inner sides by a light-transmitting infrared-reflecting coating and arranged in a layer in contact with each other with their longitudinal axes parallel, whereby light may be transmitted through the unit transverse to the longitudinal axes of the tubes while infrared energy is reflected.
Claim 3
Dependent Claim
15 words
A unit as claimed in claim 1 wherein adjacent tubes are bonded to each other.
Claim 4
Dependent Claim
22 words
A unit as claimed in claim 2 wherein said layer of tubes is arranged with longitudinal axes of the layer being co-planar.
Claim 5
Dependent Claim
73 words
A thermal insulating glazing unit comprising two glass panes spaced apart parallel to each other, and a plurality of elongated sealed and evacuated glass tubes having respective longitudinal axes, the tubes being arranged in a layer between said glass panes with respective longitudinal axes of the tubes parallel to said panes and to each other, said tubes being adjacent each other and covered on their respective inner sides by a light-transmitting infrared-reflecting coating.
Claim 6
Dependent Claim
73 words
A thermal insulating glazing unit comprising two glass panes spaced apart parallel to each other, and a plurality of elongated sealed and evacuated glass tubes having respective longitudinal axes, the tubes being arranged in a layer between said glass panes with respective longitudinal axes of the tubes parallel to said panes and to each other, said tubes being adjacent each other and covered on their respective inner sides by a light-transmitting infrared-reflecting coating.
Claim 7
Dependent Claim
31 words
A unit as claimed in claim 4 wherein at least some of said tubes are arranged in a co-planar layer parallel to the panes, adjacent tubes being bonded to each other.
Claim 8
Dependent Claim
26 words
A glazing unit as claimed in claim 5 wherein said tubes are disposed at a distance of between 5 mm and 50 mm from said panes.
Claim 9
Dependent Claim
25 words
A unit as claimed in claim 6 wherein said tubes are arranged at a distance of between 10 mm and 15 mm from said panes.
