Abstract

378. Sauvage, F. Jan. 6. Optical apparatus for projecting aerial images. - Projection apparatus of the "Phantom Bouquet " type is applied to advertising purposes. A brightly illuminated panel 2 carrying the advertisement to be projected is combined with a convergent optical system such as a concave mirror 3 or a convergent lens 5 adapted to give a real image 4 of the advertisement in space without the use of a screen. The mirror or lens may be oscillated by clock-work to cause the image to move so as to attract attention.
