  • Patent number: 5407518
    Abstract: The present invention is a device for separating a toner cartridge hopper from its mounting member so that the cartridge can be reliably resealed and refilled with toner for repeated use. A container holds the cartridge while leaving the outer edge of the gasket exposed. In one embodiment, the container is provided with wheels that travel in a track. The container moves linearly along the track past a blade that cuts away the outer edge of the gasket. In a second embodiment, the container is positioned on a rail aligned to pass between two spaced-apart blades. The rail is mounted on a linear bearing so that the rail moves linearly past the blades to remove both gasket outer edges in a single pass. By removing the outer edges of the gasket, the welds that join the hopper and mounting member to the gasket are broken and the hopper can be separated from the mounting member.

  • Patent number: 5401511
    Abstract: Methodologies have been developed and certain recognizing substances and crosslinking reagents have been identified to modify liposomes. Crosslinking reagents link residues on the liposomal surface to the residues offered by certain recognizing substances. The crosslinking reagents include glutaraldehyde (GAD) and a water soluble carbodiimide, preferably, 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC). The recognizing substances include gelatin, collagen, and hyaluronic acid (HA). Following these methodologies, recognizing substances can be utilized as an adhesive or glue to attach the liposomes onto a target area. These "bioadhesive" liposomes offer potential advantages as a microscopic drug delivery system.

  • Patent number: 5398458
    Abstract: The present invention generally relates to a process of and apparatus for manufacturing tile mosaics from at least two stone slabs, such as marble or granite slabs. The process comprises the steps of: a) cutting each of the two slabs into a matrix of pieces while maintaining the original orientation of the pieces, b) classifying the pieces of each matrix into two or more sets of pieces, c) intermixing a first set of pieces of one slab with a second set of pieces of another slab while maintaining the original orientation of the pieces, thereby forming the mosaic. The cutting apparatus comprises: a) a platen having a resilient layer for supporting the slab, b) a gantry table saw having a plurality of blades and a rotatable table for supporting the platen, and c) a hold-down rack for securing the slab and platen during cutting. At least two grippers are use to intermix at least one set of pieces from one slab with at least one set of pieces from a second slab to form the mosaic.

  • Patent number: 5397398
    Abstract: The present invention relates to a composition and method for opening clogged drains. Specifically, the liquid drain opener composition of the present invention comprises about 70%-93% by weight sulfuric acid; about 1%-23% by weight water; about 0.01%-5% by weight of at least one corrosion inhibiting agent; and, about 0.01%-28.99% by weight of at least one surfactant. The drain opener composition may also contain mineral oil and inert filler materials, such as salt. The present invention is also directed to a method of opening clogged drains comprising the steps of contacting a clogged drain with the liquid drain opener composition of the present invention; the composition applying a protective coating to metal surfaces of the drain to substantially prevent corrosion of the metal; the composition applying a protective coating to concrete surfaces of the drain to substantially prevent erosion of the concrete; and, flushing the dissolved clog with water.
