Patent number: 7857453Abstract: A method for the transport of a movie film along a film transport path, having a friction-locking connection of at least one section of the movie film to a film transport means, which is moved continuously or intermittently over a part of the film transport path, and having a pressing device which presses the movie film against the film transport means, between which and the film transport means the movie film is routed, is provided. The movie film is transported by means of feed and take-up devices, which each contain a film transport means and a pressing device and are arranged on both sides of a picture window.Type: GrantFiled: July 5, 2005Date of Patent: December 28, 2010Assignee: Arnold & Richter Cine Technik GmbH & Co.Inventor: Josef Handler

Publication number: 20100238409Abstract: An apparatus (1) for projecting images in sequence comprises a light source arranged in such a way as to direct a light beam in a direction of projection, a plurality of filters (4) with impressed shapes, able to project images corresponding to said shapes when traversed by the light beam, a conveyor element (5) defining a closed line, movable in continuous cycle, the filters (4) being associated to the conveyor element in such a way as to intercept the light beam to generate an animated effect in the projection; the conveyor (5) defines a line having at least one rectilinear segment arranged in such a way that the filters (4) intercept the light beam moving along a straight line perpendicular to the light beam. The projections can be of planar geometric shapes applicable to any lighting apparatus. In projection apparatuses currently in use, the animated effects obtained by moving filters have poor effectiveness, because the filters are constrained to move with circular trajectory.Type: ApplicationFiled: January 30, 2008Publication date: September 23, 2010Applicant: COEMAR S.P.A.Inventors: Fabio Allegri, Mauro Favalli

Patent number: 5088813Abstract: A film scanner is disclosed which comprises a dynamic film gate. The gate includes a pair of rollers for supporting the film at an imaging station and a pair of drive belts which clamp the film against the rollers. The belts are driven to advance the film through the imaging station. An integrating cylinder located above the film gate produces a line of light on the film, and light transmitted through the film in imaged onto a linear CCD image sensor. In order to insure that the end of the film is held flat at the imaging station, movable guides are provided to selectively engage the film adjacent the line of light on the film.Type: GrantFiled: July 27, 1990Date of Patent: February 18, 1992Assignee: Eastman Kodak CompanyInventor: Edward H. Wakefield

Patent number: 4474443Abstract: A device for feeding a film from a patrone in a camera, in which the film is fed by an endless caterpillar belt having pawls for engaging with film perforations. The caterpillar belt is positioned in a camera so as to match the film perforations between two film guides of the camera and is extended parallel to the film feeding direction. The caterpillar belt is driven by a set of a driving pulley and a driven pulley. The section of the pawls, taken along the film plane, is shaped to have a circular arc contour so as to contact only with the vicinity of the central portion of each film perforation.Type: GrantFiled: March 16, 1982Date of Patent: October 2, 1984Assignee: Fuji Photo Film Co., Ltd.Inventors: Hiroshi Komatsuzaki, Jiro Sekine, Shigeo Nakayama, Masashi Takamura, Hiroshi Hara, Nobuyuki Kameyama

Patent number: 4427273Abstract: A film projection system for use with a continuous film motion telecine machine includes a film guide (17, 18) which guides the film (1) past a gate (13). The film guides (17, 18) form part of two endless bands (14, 15). The parts of the bands (14, 15) in contact with the film (1) are arranged to move at substantially the same velocity as the film and there is provided means (19, 20) for varying the spacing between the bands.Type: GrantFiled: November 20, 1981Date of Patent: January 24, 1984Assignee: U.S. Philips CorporationInventors: Thomas C. Mackereth, Tadeusz Zebrowski

Patent number: 4046615Abstract: Apparatus for laminating film strips to a transport web, the laminating apparatus adaptable to handle film strips of different sizes having different perforation formats. The laminating apparatus comprises a module for positioning a film strip of a particular film size with respect to the transport web. The film strip and the transport web are then advanced through a laminating station where they are laminated together with a tape. The laminating apparatus is designed to interchangeably receive the positioning module. Thus, film strips of different film sizes may be laminated using the disclosed laminating apparatus by interchanging the positioning module to suit the particular film size to be laminated.Type: GrantFiled: October 24, 1975Date of Patent: September 6, 1977Assignee: Eastman Kodak CompanyInventor: John R. Jansen

Patent number: 4017182Abstract: A camera-processor magazine is disclosed having a cartridge for storing light sensitive roll material, together with means for driving such material out of the cartridge and upon an exposure platen. A roller curtain for shielding the material when the magazine is open also functions to guide the leading portion of the roll material across the exposure platen and into the nip of a pair of exit rollers.Type: GrantFiled: July 2, 1975Date of Patent: April 12, 1977Assignee: Itek CorporationInventor: Daniel H. Robbins

Patent number: 3938721Abstract: Pin belt mechanism for movement of a continuous strip or web which has pin feed holes. The belt is annular and the pins are attached thereto along the length thereof, between the side edges thereof. The pins are easily and readily inserted into the belt and removed therefrom. The belt is rotatable and during at least a portion of each revolution engages a ramp which accurately directs each pin into a hole in the web for movement of the web. Each pin, in a substantially vertical position, moves in a straight line as it assists in movement of the strip. The pin then smoothly moves from the hole without further engagement with the web during that rotative cycle of the belt.Each pin has one end portion which constitutes a web drive portion and which engages the web for movement thereof. The other end of each pin is a belt drive portion as the belt drive portion of the pin is movable into a recess in a drive wheel so that the pin and the belt move substantially linearly with rotative movement of the drive wheel.Type: GrantFiled: August 19, 1974Date of Patent: February 17, 1976Assignee: The Standard Register CompanyInventors: Robert W. Staneck, George R. Spaleny
