Title (EN) SHUTTER ASSEMBLY FOR A MOTION FILM PROJECTOR
(FR) OBTURATEUR POUR PROJECTEUR DE CINEMA
Abstract: front page image
(EN)A shutter assembly (130), mounted in a motion film projector (100), that includes a shutter (120) secured to a mounting bracket (240), which houses a pair of trucks (244). The mounting bracket (240) slidably houses one of the trucks (244) to accommodate for the trucks (244) passing over straight and curved portions of the track, or shutter path. The mounting bracket (240) securely houses a first truck (244) and slidably houses a second truck (244). The trucks (244) are rigidly clamped to the conveyor (104). This configuration permits the shutter (120) to be stably coupled to the conveyor (104) while permitting the shutter assembly (130) to travel along both straight and curved paths. The trucks (244) are configured to ride in a raceway (122, 124), which supports the trucks (244) and maintains the trucks (244) on a truck path. The trucks (244) include rollers (126), which roll along an elongated channel formed in the raceway (122, 124), or alternatively include air bearings (506) for carrying the truck (244) along a pressurized raceway (800).
(FR)L'invention porte sur un système d'obturateur (130) pour projecteur (100) de cinéma comportant un obturateur monté sur une bride (240) logeant une paire de chariots (244) et y coulissant pour leur permettre de passer sur les parties droites et courbes de la piste, ou du guide de l'obturateur. Ladite bride (240) abrite un premier chariot (244) et un deuxième chariot coulissant (244). Les chariots (244) sont fermement fixés au convoyeur (104). Cette configuration permet une liaison stable entre l'obturateur (120) et le convoyeur (104) et un déplacement du système d'obturateur (130) le long des pistes droites ou courbes. Les chariots (244) se déplacent sur des voies (122, 124) leur servant de support et de guide. Les chariots (244) comportent soit des rouleaux (126) roulant sur un canal allongé pratiqué dans les voie (122, 124), soit en variante des paliers pneumatiques (506) reposant sur une voie (800) sous pression.
