  • these systems include a processing station for applying a thin, uniform coating of processing fluid to the film strip following its exposure. It is desirable that the processing station internally stores a suitable quantity of processing fluid and be capable of depositing a substantially continuous, uniform layer of the latter over the entire useful length of the film strip during its advancement. Hence, it is important that the processing station provide an applicator capable of being actuated at an appropriate time following exposure, and of subsequently depositing a precisely metered amount of fluid to the film strip.
  • an important object of the invention is to provide an improved photographic system.
  • Another primary object is to provide an improved film handling cassette having an applicator for effectively applying a substantially uniform layer of processing fluid to a length of retained photographic film.
  • a further object of the invention is to provide an improved film handling cassette having a capillary type processing system.
  • a still further object of the invention is to provide a liquid applicator in which means are available for absorbing any excess of the liquid which may remain following its application to the film.
  • a compact cassette includes a reservoir container configured for receiving a processing fluid, the latter being metered by a device including a capillary component onto an exposed photographic film strip which is undergoing movement.
  • the capillary component includes a member having a channelled surface extending from within the container into tangential contact with the film strip.
  • the fluid is initially stored in a frangible pod within the container, and the capillary component comprises a cylindrical member carrying a plurality of trough-like channels extending circumferentially over a given length of the cylinder periphery.
  • the width of the channels taper from a point at their leading end to a wide mouth at the trailing end within the liquid such that the amount of fluid metered to the film varies in accordance with the location of line contact between the latter and the channels thereby permitting variation in the rate of fluid flow to the film in accordance with the rotational position of the cylinder member so as to compensate for variation in the speed of advancement of the strip past the applicator.

  • the illustrated embodiment of this invention may best be understood by first reffering to FIGS. 1 and 2 apart parallel axes.
  • An unexposed length of motionpicture film 20, provided with perforations 22 and with film leader and trailer affixed to the takeup spool 18 and to the supply spool 16, respectively, is initially substantially entirely coiled around the supply spool. Passing from the supply spool 16 to the takeup spool 18, the strip of film material sequentially travels around idlers 24, 26, 28, 30 and 32.
  • a cut-out portion of the housing member 12 defines an exposureprojection opening 38 through a portion of which image-carrying light rays may enter or leave the cassette.
  • a pressure-plate assembly 40 having an integral frame-like recessed portion 42 having a frontal aperture 44 which is aligned with a similar aperture (not shown) of the front wall 12.
  • a lightreflecting element 48 mounted in recessed portion 42 is mounted in recessed portion 42 .
  • an aperture 50 which extends through the pressure plate and is aligned with the cassette opening 38. It will thus be noted that the light-reflecting element 48 redirects these rays outwardly of the cassette through the pressure-plates aperture 50 and that section or frame of the film 20 disposed thereacross.
  • the light-reflecting element 48 may have a configuration similar to the prismatic element described in more detail in the aforementioned copending application Ser. No. 767,609 of Herbert A. Bing.
  • the pressure-plate 40 is mounted within the cassette so that it may be displaced inwardly away from the film 20. This movement is permitted against the biasing force exerted by a flat spring 52, integral with the pressure-plate 40 and bearing against a fixed stud 54. Recession of the pressure plate is thus made possible when rewinding of the film onto spool 16 is to be performed.
  • An example of means for displacing the pressure-plate 40 is illustrated.
  • An apertured plate 56 of a projection apparatus or the like (partially shown at 82 in FIG. 2) is connected with the pressure-plate by a plurality of arms or pins 58, the latter being slidably mounted for back-and-forth movement in a plurality of slots 60.
  • a solenoid 62 mounted adjacent to the plate 56, when energized slides a tang 64 at the extremity of the solenoid core 66 along the surface of a cam 68 located on the plate 56 so as to push this plate and the attached or contacted pressure-plate 40 inwardly away from film 20 against the bias of spring 52.
  • return movement of the core 66 and tange 64 is provided by the solenoid compression-spring 70.
  • the film strip 20 is advanced during exposure and projection modes by a claw arrangement in cooperation with rotation of the film spools 16 and 18.
  • a pair of spur gears 72 and 74 are mounted flush with the generally flat exterior surface of the cassettes front wall 12 within recessed portions 76 and 78 of the front wall and in axial connection to the film spools 16 and 18.
  • the present invention is pointed toward the liquidapplicator and specifically related structure of the cassette and its mounting-unit. Accordingly, certain of the hereinbefore presented details of the cassette do not constitute part of the present inventionand may take forms other than those described.
  • the liquidapplicator device 84 basically comprises a substantially liquid-tight container or chamber element 85 pivotally mounted in the cassette at 86.
  • a flangible sac or pod 88 hermetically holding a compatible processing liquid 90 of an aqueous type adapted to process the exposed-motion-picture film 20 with extreme rapidity as it passes across the processing station 34.
  • a preferred type of film structure' comprises both a photosensitive image-recording layer and an image-receiving layer in which, respectively, a developed negative image having a low silver covering power and a visible positive image having a high silver covering power are formed. This is accomplished upon application of the processing liquid by diffusion transfer of image-forming substances from the photosensitive layer to the imagereceiving layer. Assuming the processed film to be in the form of a transparency suitable for projection,'only the positive image, of dominant covering power or density, is visible.
  • the pod 88 preferably of a somewhat cylindrical shape and composed, for example, of a lead foil having plastic coating, is held against displacement by chamher portions 88a and 88b.
  • a roller or drum 92 mounted on stub shafts 94 for rotation within the chamber 85, have a peripheral portion 92a protruding through an aperture or slot 96 formed in that wall of chamber 85 which is adjacent to the film as it passes between idlers 28 and 26.
  • Resilient sealing means 98 may be provided to prevent an unwanted escape of the processing liquid at the edges of aperture 96.
  • a sharp, knife-like projection or tooth 100 extends radially outwardly from approximately the transverse peripheral center of the drum 92 for opening of the pod 88 as later explained in regard to operation of the processing station 34.
  • a liquid-absorbti've component 102 e.g., a cellulosic sponge-like or blotting material in the form of a sector is inset into the drum 92 for absorption of the remaining liquid following completion of they processing operation and release of the roller 92 as later explained in regard to FIG. 6.
  • the sponge 102 cooperates with the opening 96 of the processor housing 85 to provide sealing means therefor.
  • Fastened between the drum 92 or shaft 94 and the housing forming the chamber 85 is a torsion spring 104 which as later explained operates to return the drum to its initialposition shown in FIG. 1.
  • a plurality of minute parallel capillary grooves or channels 116 are formed longitudinally, that is, circumferentially of a section of the peripheral surface of the drum 92 as shown more clearly in FIG. 4.
  • These capillary channels are of a width and depth such that the aqueous solution will flow through them by capillary action. Hence, they provide means for conducting a measured flow of the processing liquid 90 to the film, in a manner to be subsequently described in more detail with regard to FIG. 5
  • a first or functional pivotal position of the liquid-applicator 84 is such that there is contact, in part, of that portion 92a of drum 92, which. extends through the housing aperture 96, with the emulsion side of film 20 as it passes the processing station.
  • This contact is maintained at a given pressure through bias applied to the liquid applicator 84 by a flat spring 118 bearing thereagainst. Accordingly, the film is held in a slightly tautened condition.
  • Detent means for holding the liquid applicator 84 at a second pivotal position following its use comprises a flat resilient arm 120 and a stop 122 adapted to receive and hold fixedly the tip of the arm.
  • an integral stud or tang 124 projects late rally from the lower edge 125 of the former through a slot 126 formed in the end wall 15 of the cassette.
  • the tang 124 as later explained is employed for facilitating displacement of the applicator to its second position and consequently, where the latter is in its initial position as shown in FIG. 1, the end of the tange and a lateral projection 124a are substantially flush with the exterior of wall 15.
  • a driving or coupling mechanism 106 identified with the unit 82 is adapted to provide counterclockwise rotational movement of the drum 92. Releasable engagement of the driving mechanism with the drum 92 is provided by contact of the convex and ridged plunger component 108, under bias applied by compression spring 110, with the concave fluted tip 94a (shown more clearly in FIG. 3) of the stub shaft 94.
  • a slip-clutch 112 diagrammatically shown in FIG..2 prevents damage to the mechanism through any excess of driving force.
  • the clutch 112 is connected with driving means, e.g., an electric motor (not shown) of the mounting-unit.
  • Rotational movement of the drum 92, in a counter clockwise direction as viewed in FIGS. 1, 5 and 6, is provided by the driving mechanism 106.
  • the limit of such rotation is determined by contact of the tooth with a limit stop 114.
  • Return movement of the drum 92 in a clockwise direction is provided by the torsion spring 104.
  • the pivotal mounting of the liquid-applicator 84 serves two principal functions, as follows. It provides contact of the drum 92 with the film 20 during rewind for processing purposes and it permits withdrawal of the drum from contact with the film 20 during projection or during rewind of an already processed film.
  • solenoid means 128 of the projector apparatus 82 comprise a (see FIG. 1) solenoid 128 which includes a movable core 130, a biasing compression-spring 132, an actuating or impelling arm 134, and a microswitch 136.
  • the latter includes a contactarm 138 which is adapted for actuating the microswitch 136 upon contact with the tang 124a.
  • the microswitch 136 is capable of sensing the position of the applicator 84 and thereby indicating whether the film- 20 of a particular cassette has been processed.
  • the applicator is in its first position such that upon insertion in the projector apparatus 82, the contacts 140 of microswitch 136 are forced closed thereby initiating operation of components of the projector resulting in the following.
  • the solenoid 62 (see FIG. 1) is energized so that the tang 64 is drawn against cam 68, thereby relieving the film of contact by the pressure plate 40 at the exposure aperture.
  • the coupling mechanism 106' shown in FIG. 2 engages the drum axis 94 and is energized to rotate the latter.
  • the drum 92 commences rotation in a counterclockwise direction toward the position shown in FIG. 5 such that the tooth 100 penetrates and fractures the pod 88, thereby releasing the processing liquid 90 which immediately assumes the position shown in FIG. 5.
  • the capillary area 116 is thereby prewetted.
  • the supply spool 16 is appropriately rotated in a counterclockwise direction and the unprocessed film begins its movement across the processing station 34 into coiled arrangement upon the supply spool.
  • the processing liquid 90 is supplied to the film 20 through capillary action, as provided by the capillary channels 116. It will be noted in FIG. that the lower extremities of the channels 116 are immersed in the processing liquid 90 while the upper extremities thereof are slightly above the point of contact of the drum 92 with the film 20, and that a miniscus 158 of the processing liquid is formed slightly above this point of contact.
  • the drum 92 When the drum 92 is rotated such that its capillary surface 92 is in film contact, the fluid is dispersed to the film in a controlled manner.
  • the drum provides displaceable capillary means configured for displacement between a first position out of film engagement and a second position wherein the capillary means extends from the fluid reservoir into tangential engagement with the film strip.
  • the cross section (the width and depth) of the capillary determine the flow to the film
  • the actual wetting of the film is over a greater area than such cross section since the film is brought into contact with the open edge of the channel, or that is, is in contact with fluid of the channel in a plane parallel to the longitudinal flow in the channel rather than normal thereto.
  • improved wetting of the film results.
  • the solenoid 128 When processing of the film 20 is completed, the solenoid 128 isenergized and the driving force of the coupling member 106 is relinquished in accordance with operation of the film sensor switch 142. Operation of the solneoid 128 drives its arm 134 into engagement with the tang 124 and tilts the applicator 84 back to its disengaged position where it is permanently held out of firm engagement by the detent means 120 and 122, as shown in FIG. 6. Simultaneously, as the coupling member 106 is released, the drum 94 rotates to its original position under the urging of its torsion spring 104 and any remnant of the processing liquid is absorbed by the sponge 102. It will be noted in FIG.
  • the cassette 10 is henceforth identifiable as one containing exposed and processed film and can be used as a permanent film-storage unit.
  • indicating and sensing means of the film cassette and mounting unit enabling automatic operations of rewind, processing, take-up and projection is contained in the commonly assigned US. Pat. application Ser. No. 227,083 of Rogers B. Downey et al. filed on Feb. 17, 1972.
  • a volume of 1.5-2cc. of processing liquid may be supplied in the pod 88.
  • Rotation of the drum 92 from a non-functional position and vice-versa is slightly in excess of 90, as illustrated in FIGS. 5 and 6, and occupies approximately 1 second.
  • the capillary grooves 116 are wetted sufficiently to initiate the capillary action and the film commences to move.
  • the stub shafts 94 are shown as extending through walls of cassette 12 in FIG. 2. It is therefore to be assumed that short, slightly curved slots 160 are formed in the cassette walls to permit pivotal movement of the device 84. Alternatively, however, the shafts 94 may terminate at the outer surface of the walls of the device 84 in which instance the slots 160 would be omitted.
  • drum like element 92 is illustrated as of a width greater than that of the film 20, it is to be understood that it may be of a narrower width, for example, equal to the intermediate image portion of the latter whereby marginal portions of the film are untreated by the processing liquid.
  • drum 92b of FIG. 8 An alternate means for spacing the drum from the film 20 at a given rotational position of the former is illustrated by the drum 92b of FIG. 8.
  • the flattened portion 920 At a non-liquid dispensing position of the drum,'the flattened portion 920 would be located adjacent but in spaced relation to the film 20.
  • the drum forms essentially a cylindrical segment retaining capillary means on its curved surface which may be rotated from its rest position into and back out of fluid and film engagement without otherwise moving the processing structure.
  • the drum 92 of, for example, 4 inch diameter and inchwidth has parallel capillary channels 116 formed which may, for example, be of equal width, spacing and depth, e.g., 0.010 inch and have a circumferential length of inch.
  • the capillary action may be considered as of a constant self-metering category in that the amount of processing liquid dispensed varies only with variation in the speed of film travel.
  • fluid flow is constant with film speed and has a maximum set by the capillary size.
  • the tapered capillary channels in the drum 93 illustrate an alternate means for furthering a variable metering ability.
  • the rate of flow of the processing liquid diminishes along the narrowing groove because of an augmented shear factor. Consequently, the rate at which the fluid is deposited on the film is, in this embodiment a function of both the rotational position of the drum with respect to the film strip and of the speed of the latter.
  • the fluid flow to the film can be varied, for a given film speed, by slightly rotating the drum 93 to vary the width of channel between the point of film contact and the fluid reservoir.
  • the latter arrangement is particularly useful in equipment where the film speed is not constant, for example, where the film is convolutely wound on a spool, driven a constant speed, such that the film starts at low speed and ultimately terminates at a maximum speed.
  • the drum 93 is first rotated (not shown) such that the bottom, wide portions 117 of the tapered channels 115 bridge the gap between the fluid of the reservoir and the film and provide a large fluid flow to the film (due to the large cross sectional capillaries) during the slow speed of the latter. Then, as the film speed increases during rewind, the drum is slowly rotated (clockwise in FIG. 5) to bring narrower portions of the channels 115 into a bridging relation between the film and the reservoir.
  • the latter reverse motion of the drum is provided by appropriate drive means such as means 106 of FIG. 2.
  • the surface area of the film in contact with the channel fluid and hence initially wetted is also reduced during accordingly.
