Abstract

1,177,542. Solar flare screens for tunnel entrance or exit. F. REBOUL and P. CRESCITZ. 10 March, 1967 [10 March, 1966], No. 11443/67. Heading E1J. A solar anti-flare screen 1 for the entrance of a tunnel 2 whose access road 4 may be horizontal or inclined, consists of two substantially horizontal intersecting sets of parallel blades 8, 9, each blade 8 of one set including a planar light diffusing underface 81 inclined to the vertical and an upper face having two planar portions 82, and 83, 84 portion 82 extending vertically upwards from the other, 83, 84 which has the same inclination as the underface 81 and the part 83 being diffusing or non-reflecting and the part 84 being absorbing or non reflecting, and the portion 82 being light reflecting, and a light absorbing strip 85 connecting the upper edge of underface 81 with the upper edge of the portion 82. These blades are superimposed upon the set of transversely related planar vertically disposed blades 9. In a modification (Fig. 5 not shown) the upper face portion 82 is formed by a vertical middle strip bordered on the upper and lower edges by strips inclined in opposite directions with respect to the underface at a small angle. Each set of blades may be divided into elements 5, placed on a tray 6 which covers the roadway 4 at a convenient height supported e.g. on posts 7.
