Inventors: Maloof, Ralph P.; Reynolds, Jr., Roger R.;
Assignee: Reynolds & Taylor, Inc. (Santa Ana, CA)
Primary Examiner: Yeung; James C.

Attorney, Agent or Firm: Maxwell; William H.
A solar concentrating lens and receiver operating on azimuth and altitude axes according to the position of the sun and characterized by an array of elongated transparent slats spaced for ventilation and each of prism-lens configuration with a reflective base, for both refractive and reflective focus of heat rays through a narrow slot into a receiver and onto an absorber at a focal plane where heat absorption is into a fluid media within an insulated and vacuumized internally reflective chamber. |

DETAILED DESCRIPTION We claim: 1.
A solar concentrating lens and receiver operable in alignment with incoming sunlight, and including; a multiplicity of parallel transparent elongated slats spaced apart in an array for the passage of light and to ventilate therebetween for reducing wind resistance, and each slat being of basic prism cross section with its apex disposed outwardly from a projection plane aligned with the incoming sunlight, an elongated receiver longitudinally coextensive with and spaced from the array and on said projection plane in parallel relation to each of the slats, and each of the slats having upper and lower sides inwardly divergent from its apex and angularly related for projection of the incoming sunlight through the slats and into the receiver, and having a base faced toward the projection plane and angularly disposed for reflection of the incoming sunlight through the spaces between the slats and into the receiver.
2.
The solar concentrating lens and receiver as set forth in claim 1, wherein the slats are spaced a distance apart to cast the light shadow from the apex end of one slat to the edge at the lower side of the next adjacent slat.
3.
The solar concentrating lens and receiver as set forth in claim 1, wherein the upper and lower sides of the slats are divergent to refract the incoming sunlight into the receiver.
4.
The solar concentrating lens and absorber as set forth in any one of claims 1, 2 or 3, wherein an array of said parallel transparent elongated slats extends symmetrically from opposite sides of the projection plane.
5.
The solar concentrating lens and absorber as set forth in any one of claims 1, 2 or 3, wherein each of said slats of basic prism cross section has at least one of its sides cambered to focus incoming sunlight to a focal plane within the receiver.
6.
The solar concentrating lens and receiver as set forth in claim 1, wherein the upper and lower sides of each of the multiplicity of parallel transparent elongated slats are increasingly acute in angular relation progressively toward the projection plane
