Patent GB-1065260-A (GB)
IPC: G03C8/30
Abstract: 1,065,260. Photographic printing. INTERNATIONAL POLAROID CORPORATION. Sept. 9, 1965 [Sept. 11, 1964], No. 38556/65. Heading G2A. The trichromatic colour screen of Specification 1,011,695 is made by the apparatus shown in Fig. 2. An elongated sheet 42 of lenticular film, the cylindrical lenticules running parallel to the long edge 43, is passed through the apparatus in this longitudinal direction, and exposed to a light source whose position can be altered so that the light reaches the film at different angles. As explained with reference to Fig. 1 (not shown), the area corresponding to each lenticle is exposed successively in three separate strips, for each of the three colours. The light source is an elongated ultraviolet lamp 48 in a housing 60 mounted on a plate 52. This plate rests on a supporting table 54, and may be moved with respect thereto, by means of the mechanism of Figs. 3 and 4 (not shown). Turning a knob (56) operates a mechanical arrangement which causes the plate 52, and hence lamp 48, to be moved transversely to the direction of movement of film 42. The degree of movement is indicated by a calibrated shaft (96) and dial 98. Another mechanical arrangement operated by knob (58) gives a rotational movement to plate 52 and lamp 48, again having a measuring shaft (122) and dial (124). The light is collimated by a Fresnel lens 66, which is supported so that it may be tilted by pitch screws 72. The amount of light reaching the film can be varied by moving aperture plates 44 lying just under the film, and also by varying the speed at which sheet 42 is advanced through the apparatus. The width of the exposed strip can be varied by altering the angle at which the lamp is oriented with respect to the direction of the lenticules Fig. 6 (not shown), and the position of the strip varied by varying the angle of incidence of the light Fig. 7 (not shown). Plates 62 slidably mounted on the top of housing 60 can also be used to vary both the size and position of the exposed strips.
