Abstract: An electrochemical cell is described comprising a relatively thin strip of anode material, first and second electrolyte layers coated on the opposing surfaces of the anode strip, and first and second relatively thin strips of cathode material contacting the first and second electrolyte layers, thereby forming a laminate strip with the electrolyte layers and anode strip and a single cathode current conductor strip. The laminate strip is deformed such that both of the first and second strips of cathode material contact the single cathode current conductor strip along substantially the entire length thereof. In one embodiment, the cell takes the form of a spiral, in which the conductor strip is superposed to the laminate strip and the combination is rolled lengthwise, and in another embodiment, the cell takes the form of a stack in which the laminate strip is fan-folded and the conductor strip is fan-folded and inserted between the folds of the laminate strip such that the corners of the folds of the laminate strip are perpendicular to the corners of the folds of the conductor strip.

Abstract: Nonwoven wiper having improved absorbency characteristics and streak-free wiping properties having a laminate construction including a relatively high basis weight middle layer of meltblown thermoplastic microfibers with fibers added and, on one side, a lightweight layer of generally continuous filament thermoplastic fibers having a larger average diameter with a microfiber layer on the other side. These wipers are strong, fabric-like, and are useful for a wide variety of applications including industrial uses, food services, as well as many others. The continuous filament layers provide strength and low lint properties while the combination exhibits improved wiping characteristics. The laminate is preferably bonded by application of heat and pressure and the individual compounents are preferably treated with a surfactant. The preferred combination of a layer of meltblown polypropylene microfibers with fibers added having on one side a spunbonded polypropylene filament layer and on the other a microfiber layer is particularly effective as an all-purpose wiper.

Abstract: Digital image data is automatically processed by dividing stored image data into domain blocks and range blocks. The range blocks are subjected to processes such as a shrinking process to obtain mapped range blocks. The range blocks or domain blocks may also be processed by processes such as affine transforms. Then, for each domain block, the mapped range block which is most similar to the domain block is determined, and the address of that range block and the processes the blocks were subjected to are combined as an identifier which is appended to a list of identifiers for other domain blocks. The list of identifiers for all domain blocks is called a fractal transform and constitutes a compressed representation of the input image. To decompress the fractal transform and recover the input image, an arbitrary input image is formed into range blocks and the range blocks processed in a manner specified by the identifiers to form a representation of the original input image.

Abstract: The present invention discloses high viscosity sustained release dental compositions, such as tooth bleaching or fluoride compositions, for treating tooth surfaces. For maximum results, an improved dental tray having reservoirs for holding the dental composition adjacent the desired tooth surfaces is preferably used in combination with the sustained release dental composition. The sustained release dental compositions include a high carboxypolymethylene concentration which results in very high viscosity. The high level of carboxypolymethylene makes dilution of the dental compositions from saliva difficult and time consuming so that the compositions stay within the tray reservoirs, thereby providing sustained release. The concentrated carboxypolymethylene adds a unique tackiness to the dental composition which helps retain and seal the soft tray material against the patient's teeth.

Abstract: Hard compact materials, such as rock, concrete, et cetera, are broken by igniting an appropriately designed explosive or propellant charge placed within the hole or carried in a special charge-containing device with a short barrel which is inserted and sealed into a pre-drilled hole of particular geometry. One or more approximately cylindrical holes are drilled into the material to be broken by conventional drilling, such as used in the mining and construction industries. The holes have a relatively short depth to diameter ratio, being in the range of about 2:1 to 6:1, and preferably about 3:1 to 5:1. The holes are percussively drilled with microfractures in and around hole bottoms to provide fracture initiation sites at the hole bottoms so as to provide preferred fracture initiation roughly parallel to a free surface of material being excavated. The explosive or propellant charges may be any of several commercially available explosives or propellants, including standard military and commercial rifle powders and various recently developed liquid propellants. The propellant charges, whether solid or liquid, may be placed and ignited within a charge-containing device, which includes a short barrel inserted into the holes drilled into the material to be broken. The barrel of this device may be further sealed into the holes by a helical shim sealing method.

Abstract: An AC-powerable portable computer has an interior sheet metal chassis portion (30) within which computer operating components are operatively disposed. The chassis has a removable metal access wall portion (40) and is positioned within a plastic outer housing (12) of the computer having a removable access wall (18) that outwardly overlies the sheet metal access wall portion. A key-operable security locking system (80) incorporated in the computer has a pawl portion (88) positioned within the sheet metal chassis. The pawl is selectively movable to a locking position in which it interlocks with each of the plastic and sheet metal access walls and precludes their normal removal from the computer. When the plastic and sheet metal access walls are locked to the computer in this manner, entry into the chassis interior requires that the plastic access wall be broken, and that the metal access wall be forcibly bent away from the balance of the chassis structure. Accordingly, the access walls cannot be reinstalled on the computer without leaving readily visible evidence of the forcible entry into the computer. The locking system thus provides a dual barrier to unauthorized physical entry into the chassis, and visually alerts the legitimate user of the computer that a break-in has been attempted or achieved. <IMAGE>
