Abstract
Abstract A method and apparatus for dividing a gas into two parts: a first part which is cooler and a second part which is warmer than the original gas. The apparatus includes a molecular filter for selectively passing molecules of the original gas that have a statistical distribution of velocities which is different than the statistical distribution of molecular velocities of the original gas, and a gas pump for establishing a pressure differential across the filter. The molecules which are passed through the filter will therefore exhibit a different temperature than the molecules which are not passed through.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
76 words
In a human habitation having enclosing surfaces including substantially vertical wall surfaces and a substantially horizontal ceiling surface, the improvement wherein at least one of the enclosing surfaces is formed, at least in part, by a molecular filter for selectively passing air of a different temperature than the air impinging on one side thereof and wherein means are provided for establishing a pressure differential across said molecular filter, thereby to change the temperature in the habitation.
Claim 2
Dependent Claim
76 words
In a human habitation having enclosing surfaces including substantially vertical wall surfaces and a substantially horizontal ceiling surface, the improvement wherein at least one of the enclosing surfaces is formed, at least in part, by a molecular filter for selectively passing air of a different temperature than the air impinging on one side thereof and wherein means are provided for establishing a pressure differential across said molecular filter, thereby to change the temperature in the habitation.
Claim 3
Dependent Claim
20 words
The improvement defined in claim 1, wherein said ceiling surface is formed, at least in part, by said molecular filter.
Claim 4
Dependent Claim
19 words
The improvement defined in claim 1, wherein substantially all of said ceiling surface is formed by said molecular filter.
Claim 5
Dependent Claim
14 words
The improvement defined in claim 1, wherein said molecular filter is an apertured partition.
Claim 6
Dependent Claim
33 words
The improvement defined in claim 2, wherein said means for establishing a pressure differential include means for withdrawing air from the region above said ceiling and discharging the air withdrawn outside the habitation.
Claim 7
Dependent Claim
27 words
The improvement defined in claim 1, wherein the temperature within the habitation is increased and means are provided for heating air which enters the habi-tation through doorways.
Claim 8
Dependent Claim
27 words
The improvement defined in claim 1, wherein the temperature within the habitation is decreased aNd means are provided for cooling air which enters the habitation through doorways.
