Abstract
414,220. Backgrounds for illuminated objects. GROBETY, L. H. E., 1, Rue Descartes, AsniÞres, Seine, France. July 28, 1933, No. 21284. Convention date, July 28, 1932. [Class 3 (ii).] A background for a sign or other object illuminated by artificial or natural sources of light is given an entirely dark appearance by forming it from one or more plates or sheets the face of which visible to the spectator is so disposed that it does not receive rays direct from the source. The plates may be plane or curved, fixed or movable, parallel or not, and they may be mounted on, or formed integrally with, a solid or lattice base. In the form shown, the object A is illuminated by a light source B inside a projector C and the background is formed by plates E arranged in planes that pass through a point G.
