  • Patent number: 5904812
    Abstract: High bulk tissue webs are processed sequentially through separate calendering and embossing units to optimize the balance between sheet caliper for winding tension and embossing element height for pattern definition, resulting in embossed, high-bulk tissue products with improved embossing pattern clarity. The multiple step converting process enables the use of male embossing elements having a height of about 0.04 inch or greater. The tissue webs have a Residual Waviness value of 12 micrometers or greater, which is attributable to average surface waviness values for the spot embossments being about 30 micrometers or greater.

    Abstract: A nondisassembling partition assembly comprising a partition matrix made up of intersecting first and second slotted plastic partitions, each of the partitions having at least one slot. The slots of the partitions are engaged with each other at a plurality of intersections. The matrix is held together in a nondisassembling relationship by at least one parent weld formed by heating an edge of the partitions at one or more intersections with one or more heat sources until the intersecting partitions become molten, removing the heat source or sources from edge of the intersecting partitions and allowing the partitions to cool. The parent welds formed by this process permanently secure the partitions together in the nondisassembling relationship without the use of any material other than the partitions themselves.

  • Patent number: 5895695
    Abstract: The invention described herein pertains generally to a crosslinked plumbing tube which has at least one overmolded end (e.g. nose cone or nut) attached thereto. In one aspect of this invention, the tube is more rigid than the overmolded component while in another aspect of the invention, the tube is more flexible than the overmolded component. In either embodiment of this invention, the tube provides an all-plastic waterway for a contained liquid or gas to flow through. The degree of flexibility is controlled independently controlling the density of the tube polymer and the overmolding polymer. In one aspect of the invention, the tube and the overmolding polymer are both partially crosslinked to independent first degrees prior to the overmolding process. Subsequent to the overmolding process, the crosslinking is continued to a higher degree for both polymers.

The linear extrudate or pellet can have any arbitrary cross-section or can be a regular geometric shape. Typically the thermoplastic polyvinyl chloride polymer and the wood fiber are combined and extruded in the form of a pellet. The pellet can be then taken, placed in an extruder and extruded in the form of a structural member. The composite material of the invention can be used to form structural members having high modulus (greater than about 500,000 psi). The thermoplastic structural members of the invention can then be recycled to form new thermoplastic.

  • Patent number: 5814403
    Abstract: A computer model calculates a critical aspect ratio for a discontinuous fiber composite having fibers dispersed in a matrix. The critical aspect ratio is a function of the elastic modulus and the cohesive energy of the fiber and the matrix. The composite incorporates physical features such as fiber shape features or additives in the fiber or matrix which adjust the elastic modulus and/or cohesive energy of the fiber, of the matrix or both to a value different than the corresponding value for unmodified fiber material or matrix material. These adjustments are selected so that the critical aspect ratio for the material including the modifications will be less than the corresponding critical aspect ratio for the material without the modifications. The resulting composite provides enhanced load sharing between fiber and matrix.

  • Patent number: 5800883
    Abstract: An airbag of an airbag restraint system mounted on an automotive vehicle and adapted to protect a vehicle passenger in a serious vehicle collision. The airbag is formed of front and rear side sheet-like members which are sewn with each other at their peripheral portions to be bag-shaped. Each sheet-like member includes a cloth which is woven with warp and weft yams formed of polyester resin or nylon 6, 6 fibers. The cloth is impregnated with a resinous material including a polyurethane resin adhesive for the fibers, so that the yarns of the sheet-like member are bound with each other thereby effectively preventing fray from occurrence even upon cutting of the sheet-like member.
