Abstract

759,325. Windows. OWENS-ILLINOIS GLASS CO. Aug. 27, 1954, No. 24931/54. Class 20(3). A fenestration comprises outer and inner glass walls 0, 1, spaced from one another with the outer face o<SP>1</SP> of the outer wall and the inner face i<SP>2</SP> of the inner wall having vertical ribs 27, 28 thereon shaped in such a way that light received on the first face at large azimuth angles, e.g. rays L<SP>2</SP>, L<SP>5</SP>, is redirected by refraction and internal reflection so that it is emitted from the fourth face at acute angles. The second and third interfaces o<SP>2</SP>, i<SP>1</SP> comprise prisms 29, 30 arranged in horizontal rows and shaped so that light L received at an angle S above the horizontal is refracted in a horizontal direction between these two faces and then refracted upwardly to the ceiling.
