Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
79 words
Apparatus for collecting, concentrating, and transmitting solar energy, including at least one reflector surface for directing the solar rays to a focus area, the reflector surface having a nadir and a ridge, absorption means disposed at least in part in said focus area, a heat transfer medium external to the focus area, and a heat conduit operatively interconnecting said absorption means and said transfer medium, each of the absorption means, transfer medium and heat conduit disposed above the nadir.
Claim 2
Dependent Claim
79 words
Apparatus for collecting, concentrating, and transmitting solar energy, including at least one reflector surface for directing the solar rays to a focus area, the reflector surface having a nadir and a ridge, absorption means disposed at least in part in said focus area, a heat transfer medium external to the focus area, and a heat conduit operatively interconnecting said absorption means and said transfer medium, each of the absorption means, transfer medium and heat conduit disposed above the nadir.
Claim 3
Dependent Claim
14 words
The apparatus of claim 1 wherein the collector absorption means is a rectangular strip.
Claim 4
Dependent Claim
17 words
The apparatus of claim 1 wherein the collector absorption means is a metallic bar T-shaped cross section.
Claim 5
Dependent Claim
24 words
The apparatus of claim 1 wherein the reflector consists of two surfaces disposed at 90 degrees to each other to provide a V-shaped groove.
Claim 6
Dependent Claim
12 words
The apparatus of claim 1 wherein the reflector is a parabolic curve.
Claim 7
Dependent Claim
40 words
The apparatus of claim 1 wherein the reflector includes both a V-shaped and a parabolic shaped portion, and the collector absorption means is substantially rectangular in shape with a semi-circular edge disposed opposite the direction of the approaching solar rays.
Claim 8
Dependent Claim
15 words
The apparatus of claim 1 wherein the absorption means includes a plurality of secondary reflectors.
Claim 9
Dependent Claim
83 words
Apparatus for collecting, concentrating, and transmitting solar energy, including at least one reflector surface for directing the solar rays to a focus area, a planar absorption means separated from and located above the apex of the reflector, said adsorption means oriented substantially vertically and disposed at least in part in said focus area, a heat transfer medium external to, and at least partially above the focus area, one co-extensive edge portion of said absorption means interconnecting said absorption means and said transfer means.
Claim 10
Dependent Claim
83 words
Apparatus for collecting, concentrating, and transmitting solar energy, including at least one reflector surface for directing the solar rays to a focus area, a planar absorption means separated from and located above the apex of the reflector, said adsorption means oriented substantially vertically and disposed at least in part in said focus area, a heat transfer medium external to, and at least partially above the focus area, one co-extensive edge portion of said absorption means interconnecting said absorption means and said transfer means.
Claim 11
Dependent Claim
27 words
The apparatus of claim 8 wherein an edge of the rectangular planar absorber is connected directly to the external heat transfer surface of a fluid conveying means.
Claim 12
Dependent Claim
40 words
The apparatus of claim 8 wherein the reflector surface is a parabolic curve and the absorber is a T-shaped monolithic metallic cross section, with the top horizontal portion of said T-shaped absorber being above the zenith of the reflector surface.
