Abstract: A transparency film assemblage for use with a camera includes a mount with an aperture therethrough. A film frame have a photosensitive layer is bonded to the mount in a position to cover the aperture. Secured to the mount is a foil sheet folded upon itself to form a moisture impermeable envelope. Within said envelope is a foraminous pad impregnated with developing liquid. Following exposure of the film frame the envelope is opened, the pad is laminated to the photosensitive layer of the film frame and the foil sheet is refolded to encompass the mount, pad and film frame in a light impermeable envelope suitable to be ejected from the camera while film developing continues.

Abstract: A method and apparatus for simultaneously processing both sides of a film sheet include a pair of carrier webs extending through a nip defining mechanism and a dispenser for depositing a bead of the processing material on the carrier webs in the nip. The carrier webs are advanced through the nip by a distance greater than the length of the film sheet to be processed in order to spread the processing material, and then retracted and separated. The film sheet is fed to between the carrier webs at those areas which are covered with processing material. The carrier webs with the film sheet between them are advanced through a gap of predetermined width to press the processing material on the carrier webs into contact with the film sheet, thereby forming a sandwich. The film sheet remains in the sandwich for a suitable imbibition time, after which the film sheet is delivered. In one embodiment, the processing material takes the form of a frozen body which is deposited onto the carrier webs and melted.

Abstract: A method and apparatus for processing discrete rapid access of photographic film sheets exemplified by diffusion transfer film and film processing in which one or more sheets to be processed are supported on the working surface of one of two webs trained to pass through a processing gap defined by a pinch roller pair, for example. The discrete sheets are secured to either or both of the webs by adhesive means which may be releasable where the sheet being processed to be discharged as a product or permanent where the sheet or other component of the film system is to be retained for disposal with the web to which it is secured. The method and apparatus is applicable to single sheet film systems or to negative/positive film sheet systems wherein the image of an exposed negative is transferred to a positive sheet upon the application of processing fluid therebetween.

Abstract: Processing apparatus for spreading processing fluid uniformly over photochemical layers on one or more photographic sheets by progressive pressure applied by rolling surfaces provided on large diameter calendering members. To achieve the large diameter rolling surface, the calendering members are defined by cylindrical sectors having a circumferential length corresponding to the length of sheets to be processed and supported by means effective to bring the respective cylindrical surfaces of both members into contact with opposite sides of the processed sheets. In one embodiment, the calendering members are semi-cylindrical, whereas in another embodiment the members are quadrants of cylinders.

Abstract: A high voltage, low impedance laminar battery comprising a stack of series connected cells confined under pressure in a housing. The cells comprise laminar anodes, cathodes and separators. The cells are connected in series by laminar conductive intercell connectors. An annular spacer is associated with each cell. The spacers are separated by interdigitated ones of the separators and intercell connectors.

Abstract: The method of making a laminar battery including the steps of contacting the cellophane side of a laminate of cellophane and zinc powder adhered to the cellophane with a polymeric binder with a cathode slurry of carbon and manganese dioxide in an aqueous solution of electrolytes, coating the zinc side of the laminate with a carbon slurry, and contacting the carbon slurry with a conductive plastic current collector, and cells and batteries made by this process.

Abstract: A laminar triplex structure for use in the manufacture of electrical cells and batteries, cells and batteries made therefrom, and methods of making the same. The laminate comprises a thin flat sheet of separator material, a layer of metallic particles on one surface of the separator sheet and adhered thereto with a binder, and a layer of conductive plastic adhered to the layer of metal particles. The laminate is made by the process of coating a dispersion of metal particles in a solution of a polymeric binder in an organic solvent over the separator, drying to remove the solvent, coating over the dried metal layer with a dispersion of conductive particles in a solution of a polymer in an organic solvent, and drying to remove the solvent.

Abstract: A laminar battery comprising subassemblies made by laminating cellophane to a sheet of conductive plastic on which a series of metallic electrodes have been formed in a series of regions within the confines of the sheet, in which the cellophane is caused to adhere to the plastic and to the electrode patches by feeding the cellophane and the conductive plastic between nip rolls under pressure and supplying a small amount of an aqueous bonding composition containing a small amount of a water soluble bonding agent between the layers ahead of the nip in the rolls. The laminate so made is dried in air and may be rolled for storage and later assembly into batteries. Electrical cells and batteries made with the process just outlined.

Abstract: A method of sealing a laminar battery in which the central region of the battery is cooled and held under pressure while the peripheral regions of the battery are heated under the same or a lower pressure. The thicknesses of the materials are chosen so that the completed battery is substantially as thick at the edges as in its central regions.
