Abstract

1,201, 103. Slide projectors. GAF CORP. April 2, 1968, No. 15883/68. Heading G2A. A slide projector for use with slides having a subject portion and a title portion 28 on the opaque frame of the slide 18, has means for displaying the title, as illumined by projector lamp 14, on a screen 44 for viewing by the operator only. A lens 48 forms the viewed title image 46. In another form, intermediate mirrors, one of which is axially adjustable, direct the image 46 on to the screen 44. Alternatively, the screen may be omitted and the title viewed in the final mirror. In a further variation, lens 48 and screen 44 are omitted and the illumined title is viewed directly through mirrors.
