Abstract
Abstract A heat sink is disclosed which consists of a permanently sealed container which contains LiClO4.3R2O, NH4Al(SO4)2.12R2O or (COOH)2.2R2O, where R is hydrogen or deuterium. The heat sink can be used in combination with a radiator to protect electronic circuitry or other equipment from temporary overheating.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
52 words
A method of storing heat comprising repeatedly transferring heat to a heat sink which comprises a compound selected from the group consisting of LiClO 4 .3R 2 O and (COOH) 2 .2R 2 O, where 100% of each R is independently selected from 0 to 100% hydrogen and 0 to 100% deuterium.
Claim 2
Independent Claim
52 words
A method of storing heat comprising repeatedly transferring heat to a heat sink which comprises a compound selected from the group consisting of LiClO 4 .3R 2 O and (COOH) 2 .2R 2 O, where 100% of each R is independently selected from 0 to 100% hydrogen and 0 to 100% deuterium.
Claim 3
Dependent Claim
15 words
A method according to claim 1 wherein said compound is LiClO 4 .3H 2 O.
Claim 4
Dependent Claim
15 words
A method according to claim 1 wherein said compound is (COOH) 2 .2H 2 O.
Claim 5
Dependent Claim
15 words
A method according to claim 1 wherein said compound is (COOH) 2 .2D 2 O.
Claim 6
Independent Claim
66 words
A method of protecting electronic circuitry from temporary overheating comprising (1) transferring heat from said circuit to a heat sink comprising a compound selected from the group consisting of LiClO4.3R 2 O and (COOH) 2 .2R 2 O, where 100% of each R is independently selected from 0 to 100% hydrogen and 0 to 100% deuterium; and (2) radiating said heat away from said heat sink.
Claim 7
Independent Claim
66 words
A method of protecting electronic circuitry from temporary overheating comprising (1) transferring heat from said circuit to a heat sink comprising a compound selected from the group consisting of LiClO4.3R 2 O and (COOH) 2 .2R 2 O, where 100% of each R is independently selected from 0 to 100% hydrogen and 0 to 100% deuterium; and (2) radiating said heat away from said heat sink.
Claim 8
Dependent Claim

A method according to claim 5 wherein said compound is LiClO 4 .3H 2 O.
Claim 9
Dependent Claim
15 words
A method according to claim 5 wherein said compound is (COOH) 2 .2H 2 O.
Claim 10
Dependent Claim
15 words
A method according to claim 5 wherein said compound is (COOH) 2 .2D 2 O.
