  • Patent number: 5328534
    Abstract: A method of forming a transferable pattern or image of an inorganic film by coating an embossed substrate with an inorganic layer, that may comprise one or more films, over both recessed and raised surface portions, adhesively laminating a transfer substrate to the inorganic layer coating the raised surface portions of the embossed substrate and separating the embossed substrate and the transfer substrate. The adhesive is selected such that the bond between the transfer substrate and the inorganic film on the raised surface portions is greater than the bond between the inorganic layer on the raised surface portions and the embossed substrate.The embossed substrate resulting after removal of the inorganic layer coating the raised surface portions may be modified to include additional inorganic layers over the recessed surface portions by tinning or electroplating methods such that this thickened inorganic layer may also be transferred from the embossed substrate to a transfer substrate as set forth above.

    Abstract: A corrosion resistant barrier is provided for isolated circuity. An isolated circuit (10, 12) with raised interconnection features (16, 18) having a corrosion resistant gold coating (34) is formed on a reusable stainless steel mandrel (22) which is provided with indentations to define raised features. A seed layer (32) of copper is electroplated on the mandrel in a pattern of the isolated circuit to be formed. The copper seed layer (32) is then followed by electroplated layers of gold (34), nickel (36) and copper (38) until a total desired conductor thickness is achieved. A dielectric substrate (44, 46) is laminated on the multilayer conductive traces of the circuit. After removal of the multilayer circuit from the mandrel, a predrilled dielectric coverlay (50) is laminated to the circuit with holes in the coverlay receiving the raised circuit features (52). The finished part is then etched to remove the copper seed layer from the raised features.

  • Patent number: 5326415
    Abstract: The invention is a refastenable mechanical fastening system, made of free formed prongs joined to a substrate. The prongs taper and are nonperpendicularly oriented relative to the plane of the substrate. The prongs may also have an azimuthal angle relative to the machine direction of the substrate. Each prong has an engaging means projecting laterally from the periphery of the prong. The free formed prongs are manufactured by the process of extruding liquid material through the meshes of a deposting member onto a moving substrate to form the base of the prong, stretching the liquid material in a direction parallel to the plane of the substrate, severing the stretched material to form the distal end and engaging means of the prong. The advantageous usage of the fastening system in an article of manufacture, such as a disposable absorbent article specifically a diaper, is also disclosed.

  • Patent number: 5326411
    Abstract: Belts used in agricultural applications and particularly in round, hay balers have inherent problems created by their predominant process of manufacture. This process often involves cutting a large processed sheet of material into the narrow strips which form the core of the belt. The method disclosed herein produces a belt with a folded edge, a fabric wrapped edge, or an edge that is reinforced with a hard elastomer. These belts have strengthened longitudinal edges and an increased cross-sectional modulus at the edges which alleviates many problems associated with current hay-baler belts.

  • Patent number: 5317657
    Abstract: A waveguide structure is directly extruded onto a surface from a nozzle placed a predetermined distance above the surface and which is moved relative to the surface, preferably by means of a translation table. The predetermined distance is preferably maintained constant and the speed of relative motion regulated to achieve a uniform degree of molecular orientation within the extruded material, thus maintaining a sufficiently uniform refractive index along the axis of the waveguide. Partitions within the nozzle allow the formation of a layered waveguide or the simultaneous formation of concentric cladding or protective layers. The waveguides are advantageously formed as a curtain which is later patterned, by direct writing on the surface or between chips mounted on an electronic module.
