Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
118 words
A solar collector comprising a convergent lens having a concentrically serrated surface and forming the front boundary of a heating chamber, a convex reflector defining the rear boundary of said heating chamber, said convergent lens and said reflective surface being arranged so as to focus incident light upon a common target within the chamber, a housing formed integrally with said reflector, a plurality of tubular members extending radially from said housing, and a plurality of side mirrors, each of said mirrors being pivotally mounted upon the distal end of a respective one of said tubular members whereby each mirror can be adjusted to regulate the amount of light reflected through its respective tubular member into said heating chamber.
Claim 2
Dependent Claim
118 words
A solar collector comprising a convergent lens having a concentrically serrated surface and forming the front boundary of a heating chamber, a convex reflector defining the rear boundary of said heating chamber, said convergent lens and said reflective surface being arranged so as to focus incident light upon a common target within the chamber, a housing formed integrally with said reflector, a plurality of tubular members extending radially from said housing, and a plurality of side mirrors, each of said mirrors being pivotally mounted upon the distal end of a respective one of said tubular members whereby each mirror can be adjusted to regulate the amount of light reflected through its respective tubular member into said heating chamber.
Claim 3
Dependent Claim
123 words
A solar collector comprising a convergent lens having a concentrically serrated surface and forming the front boundary of a heating chamber, a convex reflector defining the rear boundary of said heating chamber, said convergent lens and said reflective surface being arranged so as to focus incident light upon a common target within the chamber, a plurality of tubular members extending radially from said chamber, and a like plurality of side mirrors, one of said mirrors being mounted at the end of each of said tubular members for reflecting additional light into said chamber, said side mirrors being pivotally mounted upon their respective tubular members so that the amount of light reflected into said chamber by each of said side mirrors can be regulated.
Claim 4
Dependent Claim
123 words
A solar collector comprising a convergent lens having a concentrically serrated surface and forming the front boundary of a heating chamber, a convex reflector defining the rear boundary of said heating chamber, said convergent lens and said reflective surface being arranged so as to focus incident light upon a common target within the chamber, a plurality of tubular members extending radially from said chamber, and a like plurality of side mirrors, one of said mirrors being mounted at the end of each of said tubular members for reflecting additional light into said chamber, said side mirrors being pivotally mounted upon their respective tubular members so that the amount of light reflected into said chamber by each of said side mirrors can be regulated.
Claim 5
Dependent Claim
133 words
A solar collector comprising a housing defining a treating chamber, a convergent lens forming the front boundary of the chamber, said lens having a first surface nearer said heating chamber and a second surface further from said heating chamber, both of said surfaces having concentric serrations, a convex reflector defining the rear boundary of said heating chamber, said lens and said reflector being arranged so as to focus incident light upon a common target within the chamber, a plurality of tubular members extending radially from said housing, and a plurality of side mirrors, each of which is pivotally mounted upon the distal end of a respective one of said tubular members whereby each mirror can be adjusted to regulate the amount of light reflected through its respective tubular member into said heating chamber.
Claim 6
Dependent Claim
133 words
A solar collector comprising a housing defining a treating chamber, a convergent lens forming the front boundary of the chamber, said lens having a first surface nearer said heating chamber and a second surface further from said heating chamber, both of said surfaces having concentric serrations, a convex reflector defining the rear boundary of said heating chamber, said lens and said reflector being arranged so as to focus incident light upon a common target within the chamber, a plurality of tubular members extending radially from said housing, and a plurality of side mirrors, each of which is pivotally mounted upon the distal end of a respective one of said tubular members whereby each mirror can be adjusted to regulate the amount of light reflected through its respective tubular member into said heating chamber.
