Terminating by a given distance from the film strip is an edge of the first surface which enables such surface to trap particles of at least a predetermined size carried by such film strip.

  • Patent number: 4170407
    Abstract: A multipurpose audio/visual film cassette including supply and takeup spools in which opposite ends of a film strip are coupled for alternate winding and unwinding during passage through a first path for film exposing, processing and projecting operations with an audio tape also coupled at least on one end with the supply spool and interwound with the film strip to pass through a separate path, and a separating web is coupled at least on one end to the supply spool and preferably extending directly to the takeup spool in a third path. The separating web is arranged to overlie the side of the film strip on which processing fluid is deposited so as to be wound in convolutions between such side and the sound tape in order to prevent adherence of the sound tape to the film strip as a result of being interwound therewith before the processing fluid has dried.

  • Patent number: 4162829
    Abstract: A yieldably resilient shock absorber is provided, which is disposed in driving relationship between a pair of gears in a photographic apparatus drive system. The yieldably resistant shock absorber is confined within an annular chamber or channel defined by complementary structure of the two gears and is adapted to absorb forces due to sudden stoppage of the film strip or to resistance to movement of the film strip by compressing the resilient shock absorber member within the confining channel. Upon cessation of the forces imposed upon the yieldable resilient shock absorber, frictional engagement between the outer surfaces of the deformed shock absorber member and the confining walls defining the channel result in a controlled release of the absorbed energy.BACKGROUND OF THE INVENTION1. Field of the InventionThis invention relates to photographic apparatus and, more particularly, to an improved drive system for advancing and rewinding film in a film cassette inserted into the photographic apparatus.2.

  • Patent number: 4155634
    Abstract: A doctoring surface conformation for applicator nozzle structures in photographic film cassette contained processors by which a coating of processing fluid may be deposited on a moving run of an exposed film strip. The doctoring surface conformation is defined as a planar surface spaced in parallel relation to the film strip which is urged toward a pair of guide tracks positioned on opposite sides of the planar surface. The sides or edges of the doctoring surface are delimited by vertical walls converging in the direction of film strip travel so as to develop a suitable hydrodynamic force in the processing fluid while minimizing the capture of minute foreign particles such as dust which may be carried on the surface of the film strip to be coated.

  • Patent number: 4150885
    Abstract: A stabilized viewing system is disclosed as having a telescope for viewing n object by an observer when the object is remotely located from the observer, a camera for timely photographing a succession of pictures of the object on a film that is processed immediately prior to exposure of the object of the film by a processing fluid which causes a positive image to be produced on the film after exposure of the object on the film which may be viewed by the observer immediately thereafter, a unique movable linkage-type servomechanism connected between the telescope and the camera for enabling one or the other to be selected as desired by the observer, in order that he may either view the object directly or the filmed image thereof, and a magnifying eyepiece disposed in such manner with respect to the telescope and the film of the camera that either one or the other may be observed in magnified form.

  • Patent number: 4147408
    Abstract: A back projection viewing screen comprising two parallel transparent sheets of plastic, each having its faces optically configured. The surfaces have the following characteristics arranged in the order from the projection side to the viewing side: (1) an ordinary circular Fresnel lens to which a light frosted texture has been applied; (2) a series of parallel vertical convex circular lenticulations joined by sharply defined cusps; (3) a series of parallel vertical convex lenticulations joined by sharp cusps and having an elliptical cross-section. The lenticulations on this third surface have a very different periodicity from that of the second surface to avoid the possibility of moire patterns; (4) the viewing surface of the screen is defined by a series of parallel horizontal convex lenticulations, each having a convex elliptical cross-section.

  • Patent number: 4145231
    Abstract: A film cleaner and method for cleaning motion picture film. The cleaner includes a friction-driven roll, spools of cleaning tape, take-up rolls to draw the tapes from the spools, means for contacting the tapes with the film, and a gearing mechanism connecting the friction-driven roll with the take-up rolls. The film cleaning method includes driving the friction-driven roll with film running through a film delivery and take-up system, contacting the surfaces of the film with the cleaning tapes, and transferring the movement of the friction-driven roll into movement of the take-up rolls to draw the tapes from the spools. Thus, the take-up rolls are driven by the friction-driven roll and essentially clean portions of the tapes contact the film.
