  • Patent number: 9987835
    Abstract: A multilayer stack of polymeric sheets can be used in thermoforming processes to make objects wherein each sheet has substantially the same shape. The stack includes at least one sheet of a thermoformable polymer, and can include many such sheets. A barrier layer is interposed between at least an overlapping portion at least two of the polymeric sheets in order to prevent fusion of the sheets in the overlapping portion during the thermoforming process. The barrier layer can include an adhesive that adheres the sheets in the overlapping portion. In formed articles including such an adhesive, the sheets can be manually peeled from one another if a suitable adhesive is selected. The stack (and object formed using the stack) can include polymeric sheets that are not thermoformable, but are adhered to the surface of a thermoformable sheet.

  • Patent number: 7670540
    Abstract: Disclosed herein are an apparatus and method for manufacturing a balloon catheter in which a non-contact type laser perforator and printer are separately provided above a primary extruder such that inflation apertures can be uniformly perforated through a non-vulcanized lumen tube and simultaneously, tube cutting positions can be printed on the lumen tube at positions uniformly spaced apart from the inflation apertures without stopping a primary extrusion process. Also, a bond preventing agent layer is coated on the lumen tube at balloon inflating portions prior to cutting the tube, to facilitate a secondary extrusion of the tube. With this configuration, continuous and accurate perforation of inflation apertures is possible and automatic tube cutting can be achieved based on the printed tube cutting positions. Also, the present invention can compensate for a time delay due to a bond preventing agent application process and achieve high productivity and minimized loss of material.

  • Patent number: 7632442
    Abstract: A method and system for manufacturing an inorganic yarn require a mixture of volcanic rock and an additive including potassium permanganate. This mixture is heated to form a melt. From the melt, a plurality of filaments are formed during a spinning process. After cooling and sizing the plurality of filaments to form fibers, the fibers are twisted to create the inorganic yarn.

  • Publication number: 20090117269
    Abstract: An electrically conductive composite material includes metallic nanostrands distributed throughout a matrix constructed of a polymer, ceramic, or elastomer. The nanostrands may have an average diameter under four microns and an average aspect ratio over ten-to-one. Larger fibers may also be included to enhance electrical conductivity or other properties. The nanostrands and/or fibers may be magnetically oriented to enhance electrical conductivity along one direction. A pressure sensor may be formed by utilizing an elastomer for the matrix. Electrical conductivity through the composite material varies in proportion to deflection of the elastomer. A composite material may be applied to a surface as an electrically conductive paint. Composite materials may be made by cutting a blank of the nanostrands to the desired shape, inserting the matrix, and curing the matrix. Alternatively, a suspension agent may first be used to dispose powdered nanostrands in the desired shape.
