Title (EN) GRAVITY-FEED ROTARY TRAY SLIDE PROJECTOR
(FR) PROJECTEUR DE DIAPOSITIVES A PLATEAU ROTATIF A ALIMENTATION PAR GRAVITE
Abstract: front page image
(EN)A slide projector (12) for projecting slides, which may be transferred into the registry with projection aperture and out of the registry with the projection aperture, solely by the force of gravity, without the need for any mechanical slide transferring apparatus. A rotary slide tray (10) is vertically arranged with the slides in a radial orientation, and the rotary slide tray is arranged over a central hub (80, 82) portion having a vertically arranged projection passage (18) formed therein. Upon rotating the rotary slide tray, slides are permitted to radially drop from the tray by the influence of gravity into the projection passage and will be caused to back-up in the passage, since they are falling entirely through the slide construction (100), formed as a double planar slide of two individual slides arranged having like horizontal edges arranged adjacent, is employed and successive cycles of the rotary slide tray are required in order to project both images of the double slide.
(FR)Un projecteur (12) est destine a la projection de diapositives qui peuvent etre transferees dans la lucarne de projection et hors de la lucarne de projection uniquement par la force de gravite sans avoir besoin d"un appareil mecanique de transfert des diapositives. Un plateau rotatif de diapositives (10) est dispose verticalement avec les diapositives orientees radialement, et le plateau rotatif de diapositives est dispose sur un moyeu central (80, 82) ayant un passage vertical de projection (18) forme a l"interieur de ce dernier. Lorsque le plateau rotatif de diapositives tourne, les diapositives peuvent tomber radialement du plateau par l"influence de la gravite dans le passage de projection et sont forcees de se soutenir dans le passage, etant donne qu"elles tombent toutes entierement au travers de la fente et s"appuient sur des diapositives se trouvant a des emplacements diametralement opposes du plateau rotatif de diapositives. Une construction de diapositives speciales (100), ayant la forme d"une diapositive a double face constituee par deux diapositives ayant des bords horizontaux identiques adjacents entre eux, est utilisee et des cycles successifs du plateau rotatif de diapositives sont necessaires pour projeter les deux images de la diapositive double.
