  • Publication number: 20080190546
    Abstract: A structure-aided method for sealing, from the outside, a liquid-leaking puncture wound in the wall of a liquid container. This method is implemented utilizing a patch body having a perimetered cavity selectively securable to the outside of such a container with the cavity overlying and facing the wound, and the cavity's perimeter surrounding the wound, and a patch pellet confined in the cavity, and possessing a liquid-reaction substance which, with the patch body secured to the container, reacts to contact with liquid leaking from the container at least by imbibing such liquid and swelling to apply wound-sealing pressure, and more preferably by additionally reacting with leakage liquid to form a sticky coagulant mass for aiding in applying sealing pressure to the wound. The patch body may be employed directly on the outside of a container, or with an intermediate, resilient gasket which centralizes the symmetrical introduction of leakage liquid into the pellet-containing cavity.

  • Patent number: 7288161
    Abstract: Embodiments of the present invention relate to adhesive compositions containing thermally-labile groups for decreasing the degradation temperature of the adhesive for reworkability of electronic components in surface mounting applications. In one embodiment, the thermally reworkable epoxy-based composition is a cured product of a multifunctional epoxide and a curing agent, the curing agent having at least one thermally-labile group. Upon heating the thermally reworkable epoxy-based composition above a desired trigger temperature, the thermally-labile group decomposes thereby effecting depolymerization in the network. Consequently, the physical properties (e.g., shear strength) of the adhesive network are severely degraded thereby enabling easy removal of the device. In another embodiment, a thermally reworkable epoxy-based composition is a cured product of an epoxide having at least one thermally-labile group and a curing agent having at least one thermally-labile group.

  • Patent number: 7279056
    Abstract: When two structural components are to be joined, for example, when an aircraft skin section is to be secured to a stringer by an adhesive bonding, it is important that the joining surface areas are well-fitted to each other to avoid the formation of air inclusions in the joint because air inclusions weaken the mechanical strength of the joint. Thus, a surface topography that is not smooth or well-fitted must be smoothed out prior to the joining. For this purpose the surface areas to be joined are optically scanned to provide topographical information for each surface area that needs to be smoothed out. The topographical information is processed to ascertain the configuration and volume of the surface topography that needs to be filled with a filler material to produce a smooth surface without hills and dales. A respective control signal is produced and fed to a dosing equipment which supplies the exact volume of filler material required for smoothing the surface topography.

    Abstract: A method and means for protecting a windshield from further damage from existing cracks or breaks due to stone or other hard object impacts on windshields. An optically clear impact resistant, high tensile strength barrier film is placed directly over the crack or break in the windshield. The barrier is preferably a clear polymeric film or clear multiples of film, but could be opaque, rubber, plastic or metal. The barrier is placed on the glass surface and in contact with the center of the crack or break. The size of the barrier is selected to eliminate the higher incidence of continued damage to the crack or break to the peripheral area. The barrier should be combined with a clear pressure backed adhesive with UV sunlight blocking ingredients to reduce degeneration. A kit can be assembled with the elements needed to place the barrier on a windshield. The barrier can also be applied in fluid form, which achieves a film.

  • Patent number: 7118641
    Abstract: A floor covering repair technique and tool includes placement of a spacer between a patch and a damaged floor covering piece before cutting through both layers. This way, the replacement patch is elevated slightly above the damaged piece and this slight elevation allows for a slight increase in the perimeter/total area of the patch, which offsets the slight retraction/contraction of the edges of the patch and/or the edges of the original flooring after the cut. This results in a more exact fit between the patch and the surrounding, original undamaged when the patch is installed.

  • Patent number: 7118640
    Abstract: The invention concerns a method for reinforcing a double-shell structure in which a cellular core (2) is arranged between a first shell (5) and a second shell (6). In the method according to the invention, at least one cavity is formed in the double-shell structure from an opening in the first shell into the cellular core (2) so that the cavity substantially extends through the cellular core (2) to the second shell. Fixative (8) is injected into the cavity. A stiff bar (7) is introduced into the cavity, whereupon excess fixative (8) is allowed to pass out of the cavity. Finally, the fixative left in the cavity is cured.

  • Patent number: 7115178
    Abstract: A method and apparatus for converting expended thermo-plastic material, specifically empty plastic bottles, into artificial rocks, by placing the empty thermoplastic bottle in the apparatus between two sliding carriages, on each of which a rock has been mounted; and each carriage attatched to a hydraulic jack, which, when the handle is pumped, moves the carriage toward the bottle which has been heated to malleability by heat lamps mounted above and sideways to the bottle, and the said heated, flexible bottle is squeezed between the two rocks mounted on the carriages, and then the bottle is rotated and the process repeated to give the bottle a rock shape. The rock shape may be further altered using a portable heat gun.

  • Patent number: 7103966
    Abstract: A method and a device for coupling a PCB sheet are disclosed. If a defective PCB is found after the manufacture of continuously arranged circuit patterns, then the defective PCB sheet portion is removed to replace it with a new PCB sheet portion. That is, a defective circuit pattern sheet 2? is removed from continuously arranged circuit patterns of a first PCB sheet 4a. After removal of the defective circuit pattern sheet 2?, the first PCB sheet 4a is position-located by means of a position locating means 12. Then the space which is formed by removing the defective circuit pattern sheet 2? is filled with a second PCB sheet 4b on which a good quality circuit pattern 2b is printed. Then the first PCB sheet 4a and the second PCB sheet 4b are coupled together by using an adhesive means 14.

  • Patent number: 7045590
    Abstract: By utilizing specially processed waste carpeting as a filler in the production of carpet backcoating, roofing materials, or other similar products, the amount of waste carpeting that is landfilled or otherwise disposed of is significantly reduced as is the need for mining the mineral fillers. Waste carpeting (post-consumer and/or waste from new carpet manufacture) containing calcium carbonate and a thermoplastic resin is collected and size-reduced to a size corresponding to the size of calcium carbonate typically used as a filler. The size-reduced waste carpeting is added as filler to at least one other material, such as polymers in standard latex, EVA, or PVC carpet backcoatings, to provide a composite used in the manufacture of a useful product (like carpet backcoating), and then the composite material is used to make the useful product (such as carpet backcoating, which is used as a primary or secondary backcoating in the manufacture of new carpeting).
