  • Patent number: 6474022
    Abstract: A weather resistant commodity stockpile and collection pond covering system made up of a plurality of sheets joined together in waterproof seams. A plurality of flexible cords are tightly encapsulated and fixed in each sheet at spaced apart locations within thermally welded prayer seams and utilized for retention of the cover system and the hanging of ballast bags. The peeling stresses on the prayer seams are transferred as shearing stresses to lap seams formed by welding choker strips to the cover sheets on either side of each prayer seam. Side cords encapsulated in edge seams along side edges of adjacent sheets are abutted together and secured by flexible ties to form joints between sheets. Those joints are made waterproof by edge flaps attached to the sheets which are extended over each joint and sealed to the face of an adjoining sheet.

  • Patent number: 6472064
    Abstract: A tab for fixing a paper web end portion of a paper roll includes a substantially parallelogram-shaped base sheet having two diagonally opposite acute angles. A plurality of linear, discontinuous cuts are formed on the base sheet in parallel with two opposite sides of the base sheet to thereby define a first portion in cooperation with one of the two opposite sides and a second portion in cooperation with the other side. The cuts extend to at least one of other two opposite sides of the base sheet. Adhesive is applied to the first and second portions on the same surface such that an appropriate nonadhesive portion is formed between adhesive applied onto the first portion and adhesive applied onto the second portion. A release sheet having a size greater than that of the tab is attached to an adhesive-applied side of the tab such that a portion thereof is projected beyond the profile of the tab. Alternatively, the release sheet assumes the form of tape.

  • Patent number: 6391806
    Abstract: The present invention provides a liquid absorbent fibrous substrate having a plurality of discontinuous cells in which a second material is disposed. This second material is selected from a broad variety of organic or inorganic solids which may provide a reinforcing effect such that a sharp instrument is prevented from passing through the new composite structure. The reinforcing materials are disposed in a discontinuous array, in a cellular form in the fibrous substrate thus providing a path for liquids to be absorbed into said fibrous substrate, while said reinforcing materials provide resistance to penetration by sharp edged instruments. When disposed in this manner, flexibility is maintained since the reinforcing materials are not disposed in a continuous pattern. Preferably, the pattern disposed is free of linear regions that provide a continuous line of penetration for sharp edges.

  • Patent number: 6391420
    Abstract: The invention is an extruded bicomponent elastomeric netting having unidirectional elasticity. Such a netting product is a non-woven article employing a non-elastic material such as polypropylene (10) in the machine direction strands and an elastic material such as a styrenic block copolymer (12) in the cross machine direction strands. The reverse arrangement, a product with “reverse strand distribution”, is also possible.

  • Patent number: 6368663
    Abstract: There is disclosed a hybrid treatment into which CVI treatment and PIP treatment are combined. A dense matrix is formed around a ceramic fiber by the CVI treatment, and a gap in the matrix is infiltrated/filled well with the matrix by the PIP treatment, so that hermetic properties are enhanced. Moreover, when a volume ratio of the matrix by the CVI treatment in the total matrix is set to about 5% or more, about 80% or less, fine cracks are present in the matrix by the PIP treatment, so that a binding force of the ceramic fiber is weakened, and Young's modulus can be reduced. As a result, a thermal stress is alleviated and a resistance to thermal shock is enhanced.
