Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
47 words
A rigid heat absorbing panel comprising an outer casing of resinous material, a central core within said casing including at least one water-tight capsule, and a substantial amount of phase change material having a melting point in the range of normal room temperature in said water-tight capsule.
Claim 2
Dependent Claim
47 words
A rigid heat absorbing panel comprising an outer casing of resinous material, a central core within said casing including at least one water-tight capsule, and a substantial amount of phase change material having a melting point in the range of normal room temperature in said water-tight capsule.
Claim 3
Dependent Claim
45 words
A heat absorbing panel as in claim 1, said phase change material being confined in said core such that the confined material has a dimension not substantially exceeding one-quarter inch in the vertical direction with respect to the intended orientation of the panel in use.
Claim 4
Dependent Claim
24 words
A heat absorbing panel as defined in claim 1, further characterized in that said phase change material is a liquid mixture of glauber salt.
Claim 5
Dependent Claim
27 words
A heat absorbing panel as defined in claim 1, further characterized in that said capsule is substantially elongated and relatively thin and defines a single central cavity.
Claim 6
Dependent Claim
35 words
A heat absorbing panel as in claim 1, further characterized in that aggregate material is intermixed with said resin in a ratio of about 50 to 90% aggregate and 50 to 10% resin, by volume.
Claim 7
Dependent Claim
32 words
A heat absorbing panel as in claim 1, further characterized in that said aggregate material is intermixed with said resin in an amount of about 85% aggregate and 15% resin, by volume.
Claim 8
Dependent Claim
39 words
A heat absorbing panel as in claim 1, further characterized in that said outer casing includes oppositely disposed wall portions defining the vertical limits of said core, said wall portions being no more than three-eights of an inch thick.
Claim 9
Dependent Claim
44 words
A heat absorbing panel as in claim 1, further characterized in that said capsule defines a pair of central cavities each having a dimension not substantially exceeding one-quarter inch in the vertical direction with respect to the intended orientation of the panel in use.
Claim 10
Dependent Claim
29 words
A heat absorbing panel as in claim 7, further characterized in the provision of a foraminous sheet encased in each of said oppositely disposed wall portions and coextensive therewith.
Claim 11
Dependent Claim
88 words
A rigid building panel comprising an outer casing including an upper half and a lower half both of which have a plurality of recesses therein, the recesses in the bottom half opening toward and being aligned with the recesses in the upper half, whereby with the upper half and the lower half of the outer casing secured together the recesses form individual cavities within a complete building panel, at least one water-tight capsule within each cavity, and a substantial amount of phase change material within each water-tight capsule.
Claim 12
Dependent Claim
88 words
A rigid building panel comprising an outer casing including an upper half and a lower half both of which have a plurality of recesses therein, the recesses in the bottom half opening toward and being aligned with the recesses in the upper half, whereby with the upper half and the lower half of the outer casing secured together the recesses form individual cavities within a complete building panel, at least one water-tight capsule within each cavity, and a substantial amount of phase change material within each water-tight capsule.
Claim 13
Dependent Claim
34 words
A building panel as set forth in claim 10 wherein the outer casing is formed of resin and aggregate in a ratio of 50 to 90% aggregate and 50 to 10% resin, by volume.
Claim 14
Dependent Claim
25 words
A building panel as set forth in claim 11 wherein the walls of said outer casing are not greater than three-eighths of an inch thick.
Claim 15
Dependent Claim
28 words
A building panel as set forth in claim 12 and further including a foraminous sheet positioned in opposite walls of the outer casing substantially centrally of said walls.
Claim 16
Dependent Claim
25 words
A building panel as set forth in claim 10 wherein the phase change material is a liquid mixture of glauber salt and a thickening agent.
Claim 17
Dependent Claim
28 words
A building panel as set forth in claim 10 wherein there are a number of capsules in each cavity having a thickness of not greater than one-quarter inch.
Claim 18
Dependent Claim
39 words
A building panel as set forth in claim 15 wherein there are two capsules in each cavity provided by an aluminum foil of approximately five mills thickness including a single central wall and an interior coating of plastic material.
