  • Patent number: 5993581
    Abstract: There is provided an adhesive composition for use as an adhesive agent for bonding a flexible lining tube on to the internal surface of an existing old pipe. Such an adhesive composition comprises: a) an epoxy resin; b) a thixotropy agent mainly containing silica fine particles; c) a lubricant mainly containing spheroidal fine particles; d) a curing agent having a sufficient compatibility with the thixotropy agent, and being used in a sufficient amount to cure the epoxy resin. In particular, the above components a),b),c) together form a main agent, and the above components b) and d) together form an auxiliary agent. Before use, the main agent and the auxiliary agent are separated from each other. When in use, the main agent and the auxiliary agent are mixed together, so as to form the adhesive composition for use as an adhesive agent for bonding a flexible lining tube on to the internal surface of the existing old pipe.

  • Patent number: 5993592
    Abstract: An apparatus and method for gluing disc halves together during manufacturing of data storage optical discs including a main support on which a first disc half is arranged in an elastic-deformation condition. A second disc half, optionally resiliently deformed to a conical configuration, is arranged under an auxiliary support axially opposed to the main support. An adhesive dispenser delivers an adhesive along the outer circumferential edge of the first disc half, following a rotation imparted to the dispenser about the respective axis. The dispensed adhesive spreads by gravity along the glued surface of the first disc half and is thereby evenly spread thereon. The second disc half is then lowered onto the first disc half to achieve mutual pairing of the first and second disc halves.

  • Patent number: 5985070
    Abstract: Method and device for stretching a web (8) of material in the manufacture of a liquid-absorbent article, having an absorption body (4) and a cover enclosing the same. The article is made from the web (8) of material being fed in its longitudinal direction, on which web one or more elongated elastic members (11-14) are fastened. The members extend at an angle to the longitudinal direction of the web and thereby subject the web to forces which are directed transversely to the longitudinal direction of the web. The web (8) of material is kept stretched in its longitudinal direction as well as in its transverse direction by mechanical restraint of the web of material adjacent to its longitudinal edge-portions (19,20).

  • Patent number: 5976289
    Abstract: A method of fabricating an instrument panel includes providing a skin which forms a surface of the instrument panel and has side face portions extending rearwardly from a front face portion and providing a panel core having a recess for defining a molding space between the panel core and the skin. The front face portion and the side face portions define a bend angle. The recess of the panel core has peripheral walls for engaging the side face portions and the peripheral walls and a surface of the recess define a regular angle which is less than the bend angle. The bend angle, for instance, is larger than the regular angle by 2.degree. to 8.degree., and preferably by 3.degree. to 5.degree.. The panel core is placed in a first die and the skin is place in a second die such that the side face portions are deflected to fit into the recess of the panel core during mold closing. The dies are closed and a foaming material is injected between the panel core and the skin to integrate the panel core and the skin.

  • Patent number: 5964979
    Abstract: The present invention includes a method for sealing a discontinuity in the surface of a substrate comprises the steps of: (a) placing over the discontinuity an article comprising (i) a melt-flowable composition characterized by a first width, and (ii) a shaped, polymeric cap having a pre-selected, cross-sectional profile characterized by a second width and a shape in which the thickness of the cup across its width, the width of the cap, or both the width and thickness of the cap vary; (b) heating the article to cause the melt-flowable composition to flow and seal the discontinuity, where the cap controls the melt-flow behavior of the melt-flowable composition to substantially confine the melt-flowable composition to the area underneath the cap; and (c) allowing the article to cool while substantially retaining the pre-selected cross-sectional profile of the cap. The present invention also includes various articles for use in the method.

  • Patent number: 5964971
    Abstract: An apparatus and method of making a thinwall guide catheter useful in delivery of therapeutic devices through a body vessel. The method comprises braiding a flat wire over the surface of a cylindrical core, placing a heat bondable polymer tube over the braid, surrounding the polymer tube with a heat shrink sleeve, heating the assembly to a temperature and for a time period sufficient to expand the core into braid interstices and bond the polymer tube to substantially only the outer surface of the braid and finally removing the heat shrink sleeve and core. The resulting guide catheter has approximately half the wall thickness of prior guide catheters and has excellent column stiffness and kink resistance.

  • Patent number: 5922158
    Abstract: A propane fuel storage tank having a fuel-containing tank body with an outer printed sleeve made of linear heat-shrink plastic material heat-shrunk in tight fitting encircling relation about the tank for preventing viewing of surface imperfections in the tank beneath the sleeve. A method of making and reconditioning propane fuel tanks is disclosed which includes loosely positioning a sleeve of such linear heat-shrinkable plastic material about the tank body and exposing the plastic sleeve to a temperature above its heat-shrink temperature to cause it to contract and tightly conform about the outer perimeter of the tank. The sleeve preferably encompasses a central cylindrical side wall of the tank, portions of the upper and lower semi-spherical end walls of the tank, and the lower foot ring, which results in a like-new reconditioned tank without the necessity for complete removal of surface imperfections and prior adhesively applied labels, or the need for complete repainting of the tank.
