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.
Abstract:
An impact resistant composite structure is constructed of a facing portion designed to blunt and fragment an armor piercing-type bullet and absorbs some of the bullet's impact force, and a base layer designed to absorb and contain the remaining impact force of the bullet fragments. The facing layer includes a plurality of closely spaced ceramic tiles embedded in an adhesive elastic resin having a suspended mixture of polymeric microspheres, which isolate each of the ceramic tiles.
Abstract:
A seal for connecting abutting first and second elastomeric sheets (14B, 16B), having overlying metallic portions including an elastomeric strip (61). The elastomeric strip is bonded to the elastomeric portions of the first and second sheets. An electrically conductive filler (64) is attached to the metallic portions of the abutting sheets. A metallic layer (80) is then plated to the conductive filler. A layer of flexible and abrasion resistant material (90) adheres to the metallic plate and to the metallic portions of the abutting sheets.
Abstract:
A repulpable pressure-sensitive adhesive stock for labels and tapes is provided comprising a paper face material providing a surface active agent and having thereon a discontinuous pattern of a pressure-sensitive adhesive segments. The surface active agent acts to detackify the pressure-sensitive adhesive segment in pulping of the construction to prevent their agglomeration.
Abstract:
An array of gravity-held-in-place-load-bearing-horizontal-modular-accessible-tiles (10), composite-modular-accessible-tiles, and resilient-composite-modular-accessible-tiles with flexible joints (14, 20) between adjacent modular-accessible-tiles in which the flexible joints are cuttable, accessible and resealable to provide accessibility to conductors disposed above or below one or more horizontal-disassociation-cushioning-layers (18, 25), requiring fluidtight-flexible-assembly-joints between adjacent modular-accessible-tiles to assemble the modular-accessible-tiles by gravity, friction, and accumulated-interactive-assemblage into a floating finished floor array without adhering the modular-accessible-tiles to the horizontal-base-surface. A horizontal-disassociation-cushioning-layer provides accommodation for the thickness variations caused by termination and crossing over of layers of conductors and also provides improved impact sound isolation. An array of gravity-held-in-place-load-bearing-horizontal-modular-accessible-tiles, composite-modular-accessible-tiles, and resilient-composite-modular-accessible-tiles with flexible joints between adjacent modular-accessible-tiles in which the flexible joints are cuttable, accessible and resealable to provide accessibility from the entire top side to a resilient substrate, to horizontal-rigid-foam-insulation or to a three-dimensional-passage-and-support-matrix formed to accept and index varying combinations of electrical conductors, electronic signal and data conductors, fluid energy conductors, fluid conductors, and outlet-junction-boxes.
Abstract:
A binding strip (10) for binding a stack of sheets together in a book-like fashion. The binder strip includes an elongated substrate (12) made of a formable material such as a strip of heavy paper. A relatively wide band of heat-activated adhesive (14) extends down the center of the substrate. Two relatively narrow bands of heat-activated adhesive (16) are disposed on opposite sides of the central adhesive band. The central adhesive band, which has a low viscosity at the application temperature, serves to bind the edges of the sheets together and to the substrate. The side adhesive bands, which are at least one-half as thick as the central adhesive band and which have a high viscosity at the application temperature, functions to secure the first and last sheets of the stack to the substrate.
Abstract:
A screeen (21) for separating and classifying smaller particles from larger particles of a particulate substance wherein the screen (21) is of a planar configuration and made from a slab of synthetic material. The screen (21) includes a plurality of spaced perforations (23) formed by cutting the slab with a pressurized stream of fluid, which method of forming produces perforations (23) of highly uniform configuration and dimensions, particularly when the slab is a composite comprising plural layers of different synthetic materials. The perforations (23) are configured to compensate for foreshortening of their top openings (27) and accelerated wear tendencies during use of the screen (21) in an inclined disposition.
Abstract:
A breathable multi-layer film laminate (20) including microporous filled film (22) bonded to continuous film (16, 26). A support layer such as a fibrous web can be adhered to the film laminate on one or both surfaces.
Abstract:
A zone treated spunbonded/meltblown/spunbonded (SMS) or spunbonded/spunbonded (SS) fabric laminate (2') that combines the separate functions of the topsheet and cuff in one component of an absorbent article. The SMS fabric laminate is treated with surfactant to form one or more hydrophilic zones (A, B or C). The untreated areas of the fabric laminate remain hydrophobic and perform the function of the cuff. The fabric laminate is treated with surfactant on both sides using a foam applicator. The application of foam produces sharp transitions (80) between the hydrophilic and hydrophobic zones.
