  • Patent number: 5266979
    Abstract: An improved film gate for a continuous motion or real-time motion picture telecine. A housing supports and transports a film in continuous motion past a frame aperture. A precision milled entry guide roller receives the film from a feed spool, edge-stabilizes the film, and directs the film to a precision milled first entry sprocket. The entry sprocket is positioned prior to the frame aperture, pin registers the film, and directs the film across the frame aperture. A precision milled exit sprocket positioned subsequent to the frame aperture receives the film after it passes across the frame aperture and pin registers the film. A precision milled exit guide roller receives the film from the exit sprocket, edge stabilizes the film, and guides the film to a drive capstan and take up reel. The precision sprockets and rollers serve as film stabilizing means. A floating guide means positioned at the frame aperture provides additional edge stabilization of the film as it is guided past the frame aperture.

  • Patent number: 4033493
    Abstract: A pin wheel feeding device includes a housing capable of being rotated about an axis. A plurality of substantially identical pins are disposed within the housing in respective alignment with a plurality of openings. Each pin includes a pair of opposing guide members. A cam member disposed within the housing is capable of being fixed in position relative to the housing. The cam member has a track formed thereon with which each of the pins is engaged with the pair of guide members thereof being located on either side of the track. The width of the track at first, second and third segments thereof is substantially coextensive with the locus of points traced by the closest adjacent points on the pair of guide members of each pin during movement of the pins along the first, second and third segments of the track.

  • Patent number: 3998369
    Abstract: An apparatus for accurately positioning a flexible strip, having lateral perforations, with respect to an image. The apparatus includes two supports, a stud member attached to the movable support and an intercepting arm attached to the fixed support. The stud member includes a working section for engagement of the lateral perforation and alignment of the strip and a biased sleeve for position maintenance of the strip. The intercepting arm stays action of the sleeve until alignment is substantially achieved.

  • Patent number: 3969828
    Abstract: An apparatus and method for removing excess coating material from chain link fabric during the manufacture of the fabric. A gang of sprocket members are arranged side-by-side on a shaft for rotation about the shaft axis. Each of the sprocket members includes a plurality of radially outwardly extending teeth having notches formed along the length thereof. Chain link fabric is passed over the gang of sprockets such that the teeth engage through respective openings formed by the wire or other members of the fabric. When the fabric is removed from the sprockets, the notches in the teeth cause intermittent hitching and release of the fabric which vibrates the fabric to remove excess molten coated material from the fabric. The gang of sprockets is arranged intermediate a coating tank and a cooling tank for the chain link fabric such that the coating material is in the molten state when it passes over the sprockets.
