Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
153 words
An improved heat exchange means comprising: a pair of concentrically arranged inner and outer spaced, closed objects, said inner object comprising a material to be heated by solar rays impinging on at least a part of its outer periphery, the space between said objects containing less than atmospheric pressure therein, the periphery of said outer object being at least partially transparent for transmitting solar rays to said inner object, an energy transfer means arranged within the space between said objects for selectively moving into contact with and away from the outer periphery of said inner object, said energy transfer means comprising a hollow configuration having input and output fluid bearing pipe means for conducting fluid through said hollow configuration for heat absorption by the fluid flowing therethrough when said energy transfer means is in contact with said inner object, and a control means for selectively controlling the movement of said energy transfer means.
Claim 2
Dependent Claim
153 words
An improved heat exchange means comprising: a pair of concentrically arranged inner and outer spaced, closed objects, said inner object comprising a material to be heated by solar rays impinging on at least a part of its outer periphery, the space between said objects containing less than atmospheric pressure therein, the periphery of said outer object being at least partially transparent for transmitting solar rays to said inner object, an energy transfer means arranged within the space between said objects for selectively moving into contact with and away from the outer periphery of said inner object, said energy transfer means comprising a hollow configuration having input and output fluid bearing pipe means for conducting fluid through said hollow configuration for heat absorption by the fluid flowing therethrough when said energy transfer means is in contact with said inner object, and a control means for selectively controlling the movement of said energy transfer means.
Claim 3
Dependent Claim
122 words
The improved heat exchange means set forth in claim 1 in further combination with: spacer means arranged on the periphery of at least one of said objects for holding said objects in spaced arrangement and forming substantially a limited contact between said objects for controlling energy flow between said objects, said spacer means comprising at least a pair of closed ended triangular members, one of said members having its base secured to the outer periphery of said inner object and the other of said members having its base secured to the inner periphery of said outer object, said members extending around the associated object forming a closed configuration and one positioned to pass laterally of the other so that their apexes intersect.
Claim 4
Dependent Claim
16 words
The improved heat exchange means set forth in claim 1 wherein: said objects comprise cylindrical configurations.
Claim 5
Dependent Claim
15 words
The improved heat exchange means set forth in claim 1 wherein: said objects comprise spheres.
Claim 6
Dependent Claim
25 words
The improved heat exchange means set forth in claim 1 wherein: said control means comprises a reversable electric motor arranged outside of said outer configuration.
Claim 7
Dependent Claim
39 words
The improved heat exchange means set forth in claim 3 wherein: said energy transfer means comprises an elongated arcuate configuration having a curvature substantially identical to the periphery of the surface of the inner object with which it contacts.
Claim 8
Dependent Claim
39 words
The improved heat exchange means set forth in claim 4 wherein: said energy transfer means comprises a convex spherical polygon having a curvature substantially identical to the periphery of the surface of the inner object with which it contacts.
Claim 9
Dependent Claim
18 words
The improved heat exchange means set forth in claim 1 wherein: said inner object comprises a hollow configuration.
Claim 10
Dependent Claim
48 words
The improved heat exchange means set forth in claim 1 wherein: said control means comprises a sensor connected to said inner object for moving said energy transfer means into contact with said inner object when its temperature reaches a predetermined value for transferring away from it excess heat.
