Abstract
Abstract An improved solar collector system includes a reflective surface to reflect solar radiation onto an energy receiver. The reflective surface is disposed along the surface of a movable support panel which is a monocoque sheet metal construction. Suitable control equipment is affixed to the support structure to enable the reflective surface to be oriented toward the sun to achieve maximum solar energy recovery.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
165 words
A solar reflector structure comprising (a) a plurality of rigid bulkhead members with each of said bulkhead members having a front surface and a rear surface and a top and bottom outer end, said front surface of each of said bulkhead members being formed in a predetermined contour; (b) a rear stressed sheet metal skin rigidly affixed to at least a portion of said rear surface of each of said bulkhead members and a front, stressed sheet metal skin rigidly affixed to at least a portion of said front surface of each of said bulkhead members thereby forming a monocoque structure wherein stresses exerted on said rear stressed skin and on said front stressed skin are distributed over the entire said reflector structure; and (c) a reflective surface supported by said front stressed sheet metal skin, said reflective surface reflecting solar radiation on a predetermined location said reflective surface having a cross-sectional contour defined by the contour of said front surface of said bulkhead members.
Claim 2
Dependent Claim
165 words
A solar reflector structure comprising (a) a plurality of rigid bulkhead members with each of said bulkhead members having a front surface and a rear surface and a top and bottom outer end, said front surface of each of said bulkhead members being formed in a predetermined contour; (b) a rear stressed sheet metal skin rigidly affixed to at least a portion of said rear surface of each of said bulkhead members and a front, stressed sheet metal skin rigidly affixed to at least a portion of said front surface of each of said bulkhead members thereby forming a monocoque structure wherein stresses exerted on said rear stressed skin and on said front stressed skin are distributed over the entire said reflector structure; and (c) a reflective surface supported by said front stressed sheet metal skin, said reflective surface reflecting solar radiation on a predetermined location said reflective surface having a cross-sectional contour defined by the contour of said front surface of said bulkhead members.
Claim 3
Dependent Claim
22 words
The solar reflector structure of claim 1 wherein said reflective surface is the polished surface of said front stressed sheet metal skin.
Claim 4
Dependent Claim
25 words
The solar reflector structure of claim 1 wherein said reflective surface is a layer of reflective material affixed to said front stressed sheet metal skin.
Claim 5
Dependent Claim
37 words
The solar reflector structure of claim 1 wherein the front surfaces of each of said bulkhead members are shaped in a substantially parabolic contour whereby said front stressed sheet metal skin is in a trough-like parabolic shape.
Claim 6
Dependent Claim
40 words
The solar reflector structure of claim 4 wherein top and bottom edge forming members are affixed to the top and bottom outer ends of each of said bulkhead members, said edge formers running substantially the length of said solar reflector.
Claim 7
Dependent Claim
40 words
The solar reflector structure of claim 4 further including axle means and bearing means, said axle means journaled into said bearing means whereby said solar reflector can be rotated in such a manner that said reflective surface faces the sun.
Claim 8
Dependent Claim
24 words
The solar reflector structure of claim 4 further including an energy collector means disposed along a focal line defined by said trough-like parabolic shape.
