Optical apparatus, applications of, actuating.-In advertising devices of the type in which objects arranged one on each side of an obliquely disposed sheet of glass are seen when illuminated, the one directly through the glass and the other by reflexion, an obturator is rotated between the objects and the source of light to cut off the light from each object in turn. Fig. 3 shows in plan an internally blacked casing B containing a sheet of glass E fixed crosswise. An object H is seen directly, and an object G bv reflexion from the glass E, through a flared sight-hole J. The obturator N has its sectors made as vanes so that it rotates by convection currents produced by a lamp M, and cuts off light from the objects H and G successively. The sectors may be large enough to cover the whole of the light opening L in the roof 0, and so darken the interior intermittently. An adjustable cowl is placed over the lamp and obturator so that the speed may be regulated. The front A of the casing B may be hinged at D and the sheet E at F, thus allowing access to the objects G, H. Alternatively, the back C and a side or sides of the casing B may be hinged, and the objects carried by shelves on the back and side. Fig. 6 shows a modified form in which the object G seen by reflexion mav be changed, a number of such objects being carried by a hand-rotated platform V. Fig. 7 shows a modified form of obturator in which helical blades N are located about the central axis, while the sectors N' may have serrated edges N<2> to soften shadows. Alternatively, the opening L, Fig. 3, may be covered with ground glass for this purpose.
