  • Patent number: 10408378
    Abstract: A three-dimensional multi-shell insulation configured to conform to the shape of a spacecraft component to be insulated. The insulation may have a plurality of nested shell layers that are displaceable relative to each other for providing natural separation between the shell layers when the insulation is used in low-pressure and/or low-gravity space-related applications. To establish the spacing between shell layers, an edge clamp may be operatively coupled to an edge portion on at least one side of each shell layer. The shell layers may have sufficient flexibility and/or may be sufficiently displaceable relative to each other to allow the insulation to be installed or removed from the spacecraft component. One or more restraints may be provided in the space between the shell layers for restricting the relative lateral and/or transverse movement between shell layers for preventing contact. Additive manufacturing may be employed to fabricate the insulation and integrate features.

    Abstract: Absorbent article comprising a liquid-impermeable cover sheet, a liquid-permeable cover sheet, and an absorbent body between the liquid-impermeable cover sheet and the liquid-permeable cover sheet. Any one or all of the liquid-impermeable cover sheet, the liquid-permeable cover sheet, or the absorbent body can be made of a corrugated web which is corrugated from a sheet material which, in the process of being corrugated, is drawn in, and optionally elongated in a direction transverse to the corrugations, alternatively drawn-in along a direction transverse to a length of the web. The corrugated web can comprise corrugations of differing heights (H1).

  • Patent number: 7045196
    Abstract: A packaging laminate and method of production are demonstrated by using a single face corrugated cardboard. The single face corrugated cardboard is supplied in rolled form and is processed through a conventional corrugated cardboard shredder to create a flexible resilient packaging material. The method of manufacture is more efficient than conventional manual feeding of standard corrugated cardboard sheets through the shredder. Various embodiments of the invention can be manufactured by adhesively bonding two or more packaging laminates and by the addition of a support layer.

  • Patent number: 6823571
    Abstract: Apparatus for manufacturing multi-layer metal feedstock material for stamping shaped parts eliminates the need for rolls of metal at the stamping site. Multilayer metal feedstock material is assembled from multiple rolls of metal stock, then folded in a zig zag fashion, or “Z-fold” configuration, whereby the multilayer metal assembly is stacked vertically, usually on conventional pallets, for ease of moving with a forklift or otherwise. The multilayer metal z-fold stack of material is then transported to a parts stamping operation where the material is used as it unfolds as a continuous feed to machines to produce shaped multilayer metal parts. This invention is most useful in making multilayer metal foil z-fold feedstock material and using the z-fold material as continuous feed to processes for making shaped multilayer metal foil parts. The layers may have non-metal layers of material, such as fiber, between the metal layers or on the outside of the metal layers.

  • Patent number: 6800355
    Abstract: This invention relates to thermoplastic interlayers for laminated safety glass with superior vacuum de-airing at elevated temperatures and superior tacking and edge sealing properties. The sheeting has surface pattern on at least one of the surfaces characterized by flat surfaces with substantially uninterrupted channels for air flow in at least two intersecting directions. The channels allow for rapid de-airing while the area roughness parameter ratio ARp/ARt in the range of 0.52 to 0.62, ARt being less than 32 &mgr;m, and area kurtosis less than 2.5, allow for ease of tacking of the interlayer onto glass and edge sealing after de-airing has been completed. Said surface pattern may also be superimposed onto a pattern which is generated by melt fracture or other means on at least one side to enhance de-airing and aid edge sealing.

  • Patent number: 6395401
    Abstract: The invention is directed to a bond-compatible composite membrane that includes a bituminous material layer and a polyester layer and its use as an intermediate layer between a building structure and exterior finishing materials. Unlike conventional composite membranes, the bond-compatible composite membrane has a rough surface that allows bonding materials to adhere to it. Therefore, mechanical devices are not needed to attach the exterior finishing materials to the building structure.

  • Patent number: 6383607
    Abstract: A mouse pad with improved self-cleaning and traction features. The mouse pad is a planar structure with a parallel top control layer and a bottom anti-skid coating. Formed on the top layer is a top control layer with a plurality of alternating, equal height, prismatic and pyramidal shapes, which provide improved cleaning and traction properties. Small troughs are formed between the adjacent shapes, which collect fine dirt and dust particles that are swept from the surface of the mouse ball during use. In one embodiment, the top control surface is made of flexible material that allows the prismatic and pyramidal shapes to bend slightly when the ball of a mechanical mouse rolls over the top surface. This bending action provides improved self-cleaning and traction features. In another embodiment, the top layer is made of transparent material. An ink layer may be applied to the bottom surface of the top layer.

  • Patent number: 6074507
    Abstract: Corrugating rolls for forming corrugated paperboard medium are given a flute valley profile having a narrow channel along the valley base between arcuate segments of the valley base that parallel the channel on opposite sides of a radial plane of symmetry. This valley base channel is of such depth as to relieve the fiber compression stress between cooperatively nipping flute tip and valley surfaces along the axial plane between respective corrugating rolls. One advantage of the invention is to increase the on-line time of plated rolls by limiting accelerated wear of the plating in the valley base channels of the rolls. The invention also provides an improved corrugating medium characterized by flute tips which are relatively less compressed as compared to adjacent flanking regions.
