    摘要: A film transport mechanism for an optical printer in which the film is positively clamped and laterally tensioned at the position of the aperture between each film advance step, so that the film lies absolutely flat in the focal plane of the lens system of the printer during exposure. This is achieved by providing registration pins and a pressure pad at one side of the film and a curved blade at the other side that move towards and clamp the film. The blade progressively tensions the film laterally against the pressure pad and registration pins.

    摘要: A film support element assembly (20) is disclosed, primarily for supporting film (42) in relation to a projection aperture in a motion picture projector having a rolling loop film transport mechanism. In a preferred embodiment the film support element (44; 44') is a so-called "field flattener" and has a cylindrically curved surface over which successive frames inthefilm are laid bythe mechanism. Cleaning means (52, 54; 154, 156; 186, 188; 220, 222; 234; 234') are provided adjacent the film path and the lens element can be displaced to bring a fresh portion of the surface into the film path. At the same time, the cleaning means remove debris from the surface. In one embodiment the lens element (44') is vibrated (234; 234') to discourage adhesion of debris.

    摘要: An alternate eye 3-d projection system has a projector (2) projecting alternate eye left and right images, has alternating eye 3-d glasses (7) alternating between left and right lens transmissiveness, and has a phase delay unit (29) synchronizing the left lens trans­missiveness to left images and right lens transmissive­ness to right images. A timing shutter (17) is driven through a mechanical link to the projector primary mechanism at a frequency proportional to the frequency of the transition between images. A sensor (21) outputs pulses according to the rotational frequency of the timing shutter. The phase delay unit receives the pulses, a multiplier (31) multiplies the frequency of the pulses, a phase lock loop (33) locks on to the frequency and a counter (35) counts the pulses. After a preset delay the counter outputs a pulse. The delay is adjustable. The counter pulse enables a 60 KHz oscillator (43). The oscillations are counted by another counter (41) and passed to a transmitter (6). The 60 KHz oscillations are disabled when the other counter (41) reaches a preset amount. The other counter (41) sets the duty cycle of the transmitter. Each of the components in the unit is duplicated in a back-up section. The back-up section is enabled when the primary phase lock loop is not locked on and the back-up phase locked loop is locked on. (Fig. 5)

    摘要: La caméra de production de vues cinématographiques tridimensionnelles comprend des lentilles de caméra "oeil gauche" et "oeil droit", ainsi que deux mécanismes de transport de film correspondants. Les images devant être enregistrées sur les films transportés par les mécanismes sont réfléchies par des mirroirs semi-transparents et les mécanismes sont conçus de sorte que les mirroirs puissent renverser les images dans le sens transversal des films. Des épreuves de contact obtenues à partir des films peuvent ensuite être simplement retournées de 180°C, afin de corriger les inversions d'images dues à la présence des mirroirs. Les épreuves de contact sont ensuite correctement orientées pour la projection.
