Abstract
Abstract An apparatus for extraction of heat from selected matter by circulating a coolant in heat-exchanging relationship with the matter as well as to a removed region where the coolant material is cooled; it is proposed to employ enclosure shape which is divided into heat rise and cold drop sections such that a coolant filling the enclosure will maintain a circulatory, heatexchanging flow in response to the natural heat differential existing between the matter adjacent opposite ends of the enclosure.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
159 words
Apparatus for freezing or maintaining a body of matter in a frozen state, comprising: an upper hollow member forming an upper enclosure; a lower hollow member forming a lower enclosure and shaped to define a chamber substantially completely enclosed by said lower enclosure; a rigid extension means joining said upper and lower enclosures; insulative means filling said rigid extension means; first conduit means extending from the upper end of said lower member and enclosure through said insulative means and upward to terminate near the upper end of said upper enclosure; second conduit means extending from the lower end of said upper member and enclosure through said insulative means and downward to terminate near the lower end in said lower enclosure; and fluent coolant substantially filling said conduit means and upper and lower members and being capable of circulating through said first and second conduits in response to temperature differential existing as between said upper and lower members and enclosures.
Claim 2
Dependent Claim
159 words
Apparatus for freezing or maintaining a body of matter in a frozen state, comprising: an upper hollow member forming an upper enclosure; a lower hollow member forming a lower enclosure and shaped to define a chamber substantially completely enclosed by said lower enclosure; a rigid extension means joining said upper and lower enclosures; insulative means filling said rigid extension means; first conduit means extending from the upper end of said lower member and enclosure through said insulative means and upward to terminate near the upper end of said upper enclosure; second conduit means extending from the lower end of said upper member and enclosure through said insulative means and downward to terminate near the lower end in said lower enclosure; and fluent coolant substantially filling said conduit means and upper and lower members and being capable of circulating through said first and second conduits in response to temperature differential existing as between said upper and lower members and enclosures.
Claim 3
Dependent Claim
27 words
Apparatus as set forth in claim 1 and wherein means are applied to the upper hollow member and upper enclosure for force cooling said fluent coolant material.
Claim 4
Dependent Claim
31 words
Apparatus as set forth in claim 1 and wherein a plurality of cooling fins are disposed about the exterior of said upper hollow member for radiating heat from said upper enclosure.
Claim 5
Dependent Claim
22 words
Apparatus as set forth in claim 1 and wherein said upper hollow member is corrugated with a plurality of undulations formed therearound.
Claim 6
Dependent Claim
208 words
Apparatus for freezing or maintaining a body of matter in a frozen state, comprising: an upper hollow member forming an upper enclosure; a chamber; a lower enclosure shaped similar to said chamber and surrounding said chamber to define a circulation space therebetween; an insulative enclosure which is shaped to surround said lower enclosure in spaced relation to define a space therebetween generally completely around said lower enclosure; insulative material filling said space inside said insulative enclosure; extension means disposed between said upper hollow member and said insulative enclosure, said extension means including insulative material to insulatively separate said upper hollow member from said lower enclosure; first conduit means extending from the upper end of said upper enclosure downward through said extension means into said lower enclosure to terminate within the upper reaches of said circulation space; second conduit means extending from the lower end of said upper enclosure through said extension means into said lower enclosure to terminate at the lower reaches of said air circulation space; and fluent coolant substantially filling said upper enclosure, said first and second conduit means and said circulation space such that fluid circulation is effected in response to temperature differential existing between said upper hollow member and said lower enclosure circulation space.
Claim 7
Dependent Claim
208 words
Apparatus for freezing or maintaining a body of matter in a frozen state, comprising: an upper hollow member forming an upper enclosure; a chamber; a lower enclosure shaped similar to said chamber and surrounding said chamber to define a circulation space therebetween; an insulative enclosure which is shaped to surround said lower enclosure in spaced relation to define a space therebetween generally completely around said lower enclosure; insulative material filling said space inside said insulative enclosure; extension means disposed between said upper hollow member and said insulative enclosure, said extension means including insulative material to insulatively separate said upper hollow member from said lower enclosure; first conduit means extending from the upper end of said upper enclosure downward through said extension means into said lower enclosure to terminate within the upper reaches of said circulation space; second conduit means extending from the lower end of said upper enclosure through said extension means into said lower enclosure to terminate at the lower reaches of said air circulation space; and fluent coolant substantially filling said upper enclosure, said first and second conduit means and said circulation space such that fluid circulation is effected in response to temperature differential existing between said upper hollow member and said lower enclosure circulation space.
Claim 8
Dependent Claim
26 words
Apparatus as set forth in claim 5 and wherein means are applied to said hollow member and upper enclosure for force cooling said fluent coolant material.
Claim 9
Dependent Claim
32 words
Apparatus as set forth in claim 5 and wherein a plurality of cooling fins are disposed about the exterior of said upper hollow member for radiating heat away from said upper enclosure.
Claim 10
Dependent Claim
22 words
Apparatus as set forth in claim 5 and wherein said upper hollow member is corrugated with a plurality of undulations formed therearound.
