Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
135 words
A method for controlling heat exchange between the universe and an enclosure constructed to support in a first portion a quantity of liquid oriented in a place of minimal exposure to solar radiation and in a second portion a quantity of liquid oriented in a place to receive a greater exposure to solar radiation, said portions separated by a member common to each portion, the steps comprising: positioning during a period of the diurnal temperature cycle the major quantity of the liquid of said first and second portions in said first portion, and positioning during a second period of said temperature cycle said major quantity of the liquid in said second portion, said common member being floatable on the liquid in said first portion and movable vertically to vary the volume of said first portion.
Claim 2
Independent Claim
135 words
A method for controlling heat exchange between the universe and an enclosure constructed to support in a first portion a quantity of liquid oriented in a place of minimal exposure to solar radiation and in a second portion a quantity of liquid oriented in a place to receive a greater exposure to solar radiation, said portions separated by a member common to each portion, the steps comprising: positioning during a period of the diurnal temperature cycle the major quantity of the liquid of said first and second portions in said first portion, and positioning during a second period of said temperature cycle said major quantity of the liquid in said second portion, said common member being floatable on the liquid in said first portion and movable vertically to vary the volume of said first portion.
Claim 3
Dependent Claim
34 words
The method set forth in claim 1 in further combination with the step of: positioning the major quantity of the liquids in said second portion when solar energy is available to said second portion.
Claim 4
Dependent Claim
51 words
The method set forth in claim 1 wherein: said first portion expands in size during its receipt of said major portion of the liquid as said common member rises and falls with the changing of liquid level in said first portion and said second portion contracts in size and vice versa.
Claim 5
Dependent Claim
12 words
The method set forth in claim 3 wherein: the liquid comprises water.
Claim 6
Dependent Claim
48 words
The method set forth in claim 3 in further combination with the steps of: sensing the temperature of the liquid in said first and second portions, and alternately positioning the major portion of the liquid in said first and second portions depending on the temperature of the liquid.
