Abstract
Abstract A solar radiation reflector, including a parabolic-trough reflecting surface, transmits solar radiation in a general line reflection on an upright heat absorber during the winter and early spring months of low to moderate sun angles and a juxtaposed overhanging heat absorber above the upright absorber during summer high-sun angle periods for producing heated transfer medium from each absorber for use in domestic water supply and refrigeration. The reflector may tilt on azimuth to zenith lines for seasonal tilting actions and/or swing East to West to compensate for daily relative sun movement.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
138 words
Solar heat absorbing device comprising a. parabolic trough reflector means having its horizontally-oriented extent in straight lines and its vertical extent along a parabola, for focusing solar radiation into a narrow, linear area, which varies vertically at various seasons of the year mounted in a general horizontal position; b. upright, generally vertical, target means depending upwardly along the length of an edge of said reflector means in position to be impinged on by the linear area reflected radiation as well as receiving direct solar radiation, and an overhang target means depending from said upright target means extending over said reflector means; c. a plurality of lengths of fluid carrying pipes mounted on said target means to receive solar radiation and having inlet and outlet means for circulating fluid therethrough; and d. said target and carried pipes being blackened.
Claim 2
Dependent Claim
138 words
Solar heat absorbing device comprising a. parabolic trough reflector means having its horizontally-oriented extent in straight lines and its vertical extent along a parabola, for focusing solar radiation into a narrow, linear area, which varies vertically at various seasons of the year mounted in a general horizontal position; b. upright, generally vertical, target means depending upwardly along the length of an edge of said reflector means in position to be impinged on by the linear area reflected radiation as well as receiving direct solar radiation, and an overhang target means depending from said upright target means extending over said reflector means; c. a plurality of lengths of fluid carrying pipes mounted on said target means to receive solar radiation and having inlet and outlet means for circulating fluid therethrough; and d. said target and carried pipes being blackened.
Claim 3
Dependent Claim
41 words
Solar heating device according to claim 1 wherein said upright target means includes wings, including fluid carrying pipes extending outwardly at an angle therefrom toward said parabolic trough for catching reflected radiation from said reflector means during morning and evening hours.
Claim 4
Dependent Claim
18 words
Solar heating device according to claim 1 wherein said plurality of pipes includes at least two separate circuits.
Claim 5
Dependent Claim
40 words
Solar heating device according to claim 1 wherein said reflector means is underlayed with a plurality of pipes for circulating fluid therethrough, and control means provides for circulating warm fluid therethrough for snow and ice removal on said reflector means.
Claim 6
Dependent Claim
61 words
Solar heating device according to claim 4 wherein said control means includes shade means to prevent direct sun on activator means for said plurality of pipes in said upright target means to prevent activation of fluid flow means therethrough when no reflected radiation is received by said control means and includes openings for reflected radiation for activation of fluid flow means.
Claim 7
Dependent Claim
26 words
Solar heating device according to claim 1 wherein said reflector means is mounted for tilting along azimuth lines to compensation for seasonal position of the sun.
Claim 8
Dependent Claim
25 words
Solar heating device according to claim 1 wherein said reflector means is mounted for East to West pivoting to compensate for the sun's daily movement.
Claim 9
Dependent Claim
47 words
Solar heating device according to claim 1 wherein the south facing edge of said reflector means opposite said upright target means includes direct solar radiation absorption means extending downward from said reflector means including a plurality of pipes mounted therein and having means for circulating fluid therein.
