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: Cells or multicell batteries are provided with vents comprising fiber-filled plastic tubes. The plastic tube walls are formed of a hydrogen-permeable, liquid-impermeable, plastic material and the fibers which fill the interior of the tube serve to maintain an open gas diffusion passage through the tube. The vents extend through seals between battery components into electrochemically active regions of the battery, into gas permeable regions of the battery outside of the electrochemically active regions, or both. The fiber filled tube can terminate in the cell interior when the end positioned within the cell is sealed with a hydrogen-permeable, liquid-impermeable, plastic layer, or the tube can extend across the battery length or width. At least one end of the tube is open to the atmosphere.

Abstract: A method of making thin flat laminar batteries in which subassemblies are made by sealing conductive intercell connectors to the inner peripheries of frames of nonconducting material and wet electrodes are applied on either side of the intercell connectors. A separator is placed over one of the wet electrodes. A series array of these subassemblies are sealed together about the outer peripheries of the frames, with electrodes of opposite polarity in adjacent subassemblies in contact with the separator. End cells are completed by frames sealed on one side to terminal collector sheets and on the other side to external surfaces of the series array.

Abstract: A method for forming a slurry cell electrode structure which serves as a component of a planar battery. The slurry electrode structure is formed in situ as a particulate dispersion of active material in aqueous electrolyte. The method utilizes a slurry precursor prepared by predepositing a liquid carried dispersion of the particulate active material over the surface of a select component, such as a separator, current collector, or intercell connector of the cell. This deposition is dried and prepared as a subassembly which is appropriately inserted within the multicell pile structure as a step in the manufacture of a multicell battery. By wetting the subassembly with a wash coat of aqueous electrolyte, in situ slurry formation is provided.

Abstract: A sound recording and reproducing system comprising a motion picture camera in which there is a synchronization system for recording segments of sound from a signal produced by a microphone associated with the camera as analog samples alternatively read into each of two analog shift registers in increments of samples corresponding to one frame time of the taking picture cycle. Means are provided for recording each such approximately timed sample sequence onto the film adjacent the frame being photographed during pulldown of the film in the camera. For playback, a projector is provided which comprises two analog shift registers each alternatively used for taking the samples recorded on the film for each frame for storage during pulldown, and then to transmit the stored samples through a filter to a loud-speaker for reproduction at a continuous rate during projection of the photographic images recorded on the film.

Abstract: A method for constructing flat batteries having improved peripheral seals. These batteries are characterized in incorporating polymeric intercell connectors, outer collector assemblies including an externally disposed sheet terminal-current collector and sheet separator components associated with thermal sealing material, the peripheries of the seal material extending outwardly from the corresponding peripheries of the current collectors and intercell connectors. To effect a seal of improved integrity as well as enlarged size, a cover sheet of material dimensionally stable at temperatures whereat the seal material and the polymeric connectors are dimensionally unstable is placed over the current collector and seal portions with which a thermal sealing bar would otherwise come in contact.
