  • Patent number: 6289939
    Abstract: A fabric grounding tape and method of making same is disclosed. In accordance with the method the tape is woven on a needle loom using polyester and stainless steel warp yarns. The yarns are maintained under tension during and after the weaving process and are subjected to a heat setting procedure while still under tension. The resultant tape has the hand or feel of a conventional all polyester tape and a low ohmic resistance, i.e. 10 ohms or less per inch. The tape can sustain a multiplicity of laundering cycles without significant increase of resistivity.

  • Patent number: 5419376
    Abstract: A fabric anchor device for attachment to awnings or the like for holding awning retaining ropes. The device comprises a woven fabric strip having a central reinforcing spine defined by paired high tensile strength reinforcement warp yarns. The spine includes a series of mutually spaced apart attachment apertures, the respective reinforcement yarns lying on opposite sides of the apertures.

  • Patent number: 5098756
    Abstract: A self-extinguishing fire resistant elastic strap material is disclosed, as is a method of fabricating the same. The material is comprised of a tubular fabric of fireproof yarns having a hollow core, elastic and hence combustible yarns being disposed entirely within the core, the elastic yarns being frictionally clampingly engaged at spaced positions to the surrounding fabric, the elastic yarns being tensioned in the formed condition of the fabric to effect foreshortening of the fabric when the tension in the elastic yarns is relaxed.

  • Patent number: 5066363
    Abstract: A method of processing pulp laps and a soluble strap material for holding such laps in a bale are disclosed. In accordance with the method the laps are maintained in the configuration of the bale by soluble straps comprised of PVA and are immersed in a pulping bath while still confined by the straps. The straps rupture and dissolve in the pulping bath releasing the paper laps. The straps are formed to maximize exposure of the PVA increments to the pulping bath to accelerate dissolving and may incorporate fillers of pulpable material to maintain the PVA increments in a separated condition.

  • Patent number: 4755407
    Abstract: A fire and wear-resistant strap material particularly useful in conjunction with fire fighting apparatus is disclosed. The strap material comprises a carrier fabric, the surfaces of which have been provided with a flexible retro-reflective coating permanently bonded thereto. The carrier fabric is preferably comprised of aramid yarns which, while having low abrasion resistance, are rendered highly wear-resistant by the retro-reflective coating, which also functions to minimize heat transfer to the supporting fabric.

  • Patent number: PP9454
    Abstract: A new and distinct variety of grape with a unique leaf resembling the maple. This cultivar is adapted as an ornamental, dooryard grape that could be grown on arbors around patios and as borders on fences. The new grape is distinguished by vigorous growth and superior disease resistance, requiring few fungicide applications, making it environmentally compatible for use around the home. The grape is also distinguished by its foliar characteristics which make it visibly different than other commercial cultivars of grape.
