Abstract
Abstract crystallization, a plurality of air channels through which ambient air may flow formed in part by said panel, and an electrical resistance element for heating said material during periods of low tariff, characterized in that said heater is in the form of a sheet, in that said panel has a plurality of depressions formed thereon where said depressions extend in the direction and form on one side of the panel a part of said air channels and on the other side of the panel a part of said chambers with the chambers alternating with the air passages, and in that the panel has a flat flanged strip extending along two sides thereof sealingly connected to said oppositely disposed wall member.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
54 words
A heat storage container according to claim 1 further characterized in that said oppositely disposed wall member comprises a second panel and in that the panels are sealingly connected together along their flanged strips and wherein the depressions of each panel are deposed opposite one another to form said chambers holding said storage material;
Claim 2
Dependent Claim
25 words
A heat storage container according to claim 2 further characterized in that said heater element is positioned between oppositely deposed depressions of said two panels.
Claim 3
Dependent Claim
18 words
A heat storage container according to claim 1 further characterized in that the depressions have undulating side walls.
Claim 4
Dependent Claim
75 words
A heat storage container accorDing to claim 1 further characterized in that said panel is folded on itself to form two folds whereby one fold is said oppositely disposed wall member and whereby portions of a single depression are positioned opposite each other to form a chamber for holding said material, and in that portions of the flanged strip on each of the said two sides of said panel are sealingly connected to each other.
Claim 5
Dependent Claim
60 words
A heating element for a storage body according to claim 1, characterized in that planar heaters which are insulated on at least one side are uniformly pressed against the storage bodies and in that an elastic mat is provided between the heater and an outside wall or between two heaters for the purpose of compensating for manufacturing tolerances and distortion.
Claim 6
Dependent Claim
20 words
A heating element for storage bodies according to claim 6, characterized in that the elastic mat consists of iron filings.
Claim 7
Dependent Claim
21 words
A heating element for storage bodies according to claim 7, characterized in that the elastic mat consists of silicon foam rubber.
Claim 8
Dependent Claim
37 words
A heating element for storage bodies according to claim 1, characterized in that it is in the form of an elastic plate of low strength, which is subjected to deformation into an undulating line between storage bodies.
Claim 9
Dependent Claim
38 words
A heating element for storage bodies according to claim 9, characterized in that the heating body consists of a heat resistant plastics foil, e.g., polyester, to which a conducting layer is applied, e.g., by vapor deposition of aluminum.
Claim 10
Dependent Claim
23 words
A heating element for storage bodies according to claim 9, characterized in that one side of every heating body faces the air channel.
Claim 11
Dependent Claim
46 words
A heating element for storage bodies according to claim 9, characterized in that separately switchable conducting layers are deposited on the two sides of a heating foil, one conducting strip being disposed in the region between two conducting strips which are disposed on the other side.
Claim 12
Dependent Claim
23 words
A heating element for storage bodies according to claim 9, characterized in that high-molecular polyethylene is used for the heating or insulating foil.
Claim 13
Dependent Claim
30 words
A storage container according to claim 1, characterized in that the heating body is embedded between two foils which are welded together along their circumference to form an airtight seal.
