Abstract

505,250. Lantern screens. CINESCOPE PUBLICITY CO., Ltd., and DICKINS, R. V. Nov. 3, 1937, No. 30172. [Class 75 (iv)] [Also in Group XVIII] In a sign in which a diffusing screen is interposed between the display panel and a light source, the diffusing screen comprising translucent areas in an opaque background, is of dish formation and partially encloses the light source. Figs. 1 and 3 show the application to a box sign in which a plate 12 bearing display matter is illuminated by lamps mounted behind diffusing screens 14 each comprising a perforated member supported by a wire 16 on the lamp support. An additional screen member 20 may be provided on the member 14. To effect more uniform illumination of the plate 12, the apertures in the screen 14 may be graduated so as to increase in size from the centre to the periphery of the screen.
