Of About The Same Composition As, And Adjacent To, The Void-containing Component Patents (Class 428/318.6)
  • Patent number: 6194060
    Abstract: An opaque, oriented polymeric film structure comprises: (a) a core layer containing a thermoplastic polymeric matrix material which has a first surface and a second surface, the core layer having a plurality of voids, substantially all or all of the voids being free from a void-initiating particle and at least some of the voids being interconnected with an adjacent void in the polymeric matrix material, the number of voids not containing a void-initiating particle being sufficient to impart a significant degree of opacity to the film structure; and (b) at least one outer or skin layer containing a thermoplastic polymeric material and an effective amount of a nucleating agent to suppress cavitation in said at least one outer or skin layer. The film structure has a smooth surface and can be tailored to provide a controlled permeability, and is particularly suitable for food packaging.

  • Patent number: 6187446
    Abstract: A silicon-based carrier matrix having a high ratio of surface area to volume is intended for use in integrated microanalysis systems. The carrier matrix comprises at least one layer of microporous silicon on a body of monocrystalline silicon. A method for producing the carrier matrix comprises electrochemical etching of a body of monocrystalline silicon, thereby to form at least one layer of microporous silicon on this body. The use of the carrier matrix for chemical sensors in integrated microanalysis systems, as well as in various sorts of chromatography, is also disclosed.

  • Patent number: 6187411
    Abstract: A stitch-reinforced sandwich panel with improved flatwise tensile strength, improved skin to core peel strength, and substantially reduced damage propagation from impact includes a relatively non-compressible foam core, a dry reinforcing layer of fibers placed on each of the opposite faces of the foam core; and high strength thread stitched with a high density of stitches over the entire panel through each of the reinforcing layers and the foam core. The skins are then impregnated with a resin system to complete the structure.

  • Patent number: 6183823
    Abstract: A support device for a computer mouse (mouse pad) comprises, extending over the lower foil made of foam material, at least one thin, colored liquid layer which is enclosed between two foils welded together along the edge in a liquid-tight manner and is visible through the transparent foil or foils. The liquid occupies the available cavity only incompletely and it spreads out in puddle-like patterns to define void spaces which change continuously due to the actuation of the mouse, thereby providing the mouse pad with an optically interesting appearance.

  • Patent number: 6170205
    Abstract: A dock seal for sealing the interface between a vehicle and a loading dock, including a resilient member and a flexible material embedded in the resilient member. The dock seal can be made by applying a liquid material over the resilient member and curing the liquid material to form a flexible coating. The liquid material can be applied by spraying, pouring, dipping or brushing. A puncture-resistant material can be positioned adjacent the resilient member before curing the liquid material. In one embodiment, the resilient member is attached to a dock seal frame and mounted to the loading dock.
