  • Patent number: 6228503
    Abstract: A recycled asphalt roofing material for use on sloped roofs, which provides the required elevated melt point without using prior art methods of oxidizing the asphalt prior to incorporation into the roofing material is provided. The recycled asphalt roofing material is made up of approximately 30% flux asphalt and approximately 70% reclaimed asphalt roofing material. The fibrous backing in the reclaimed material modifies the asphalt in such a way as to provide the required elevated melt point. The manufacturing process for recycled fiberglass mat-based roll and shingle roofing, in its preferred embodiment, consists of impregnating a roofing material backbone, such as a fiberglass or polyester mat with recycled asphalt material to form inner and outer layers of recycled material and then applying optional second inner and outer layers of standard asphalt coating to the inner and outer layers of the recycled material.

  • Patent number: 6194329
    Abstract: A reversible fabric particularly for use in the production of military rainflies is described. The fabric has first and second faces, each of which has a visually distinct color in order that rainflies and other articles made from the fabric can be used to provide inconspicuous shelter in two visually distinct environments. Each of the sides of the fabric provides requisite degrees of visual opacity and infrared reflectance, as well as other functional properties—such as water-resistance, etc. The fabric includes a dyed textile substrate and three coats of pigmented polyurethane having varying compositions; the composite fabric can be produced by a coating and/or laminating process.

  • Patent number: 6143394
    Abstract: There is disclosed the manufacture and use of nonwoven absorbent mats laminated with barrier film for manhole aprons. The absorbent aprons are used about manholes during routine maintenance of underground transformers, utility cables, etc. The nonwoven aprons are coated to prevent the absorbed liquid from leaching through. The mat is specially designed to absorb contaminated liquid very quickly. The nonwoven mat is made out of cotton shoddy fibers and/or a mixture of synthetic fibers and/or synthetic fibers only with film on one side. The mat has a 36-inch manhole opening in the center thereof. The mat is thin and lays flat to conform to the road. The thickness of the mat ranges from 0.075" to 0.25" in order to avoid any tripping hazard.

  • Patent number: 5990377
    Abstract: A dual-zoned, three-dimensional, resilient absorbent web is disclosed which is suitable as body-side liner for absorbent articles such as feminine pads, diapers and the like. When used as a liner in absorbent articles, the dual-zoned web combines the advantages of apertured films and soft, nonwoven cover layers in one structure while still being inherently hydrophilic. The liner comprises a web of wet-resilient, hydrophilic basesheet having a three-dimensional topography comprising elevated regions onto which hydrophobic matter is deposited or printed and a plurality of spaced apart depressed regions. In a preferred embodiment, the hydrophobic matter applied to the elevated regions of the basesheet comprises hydrophobic fibers in a contiguous nonwoven web which has been apertured or provided with slits or other openings, such that the apertures or openings overlay a portion of the depressed regions.

  • Patent number: 5814397
    Abstract: Hygroscopic ceramic materials which are difficult to waterproof with a silane, substituted silane or silazane waterproofing agent, such as an alumina containing, fibrous, flexible and porous, fibrous ceramic insulation used on a reentry space vehicle, are rendered easy to waterproof if the interior, porous surface of the ceramic is first coated with a thin coating of silica. The silica coating is achieved by coating the interior surface of the ceramic with a silica precursor, converting the precursor to silica either in-situ or by oxidative pyrolysis and then applying the waterproofing agent to the silica coated ceramic. The silica precursor comprises almost any suitable silicon containing material such as a silane, silicone, siloxane, silazane and the like applied by solution, vapor deposition and the like. If the waterproofing is removed by, e.g., burning, the silica remains and the ceramic is easily rewaterproofed.

  • Patent number: 5744406
    Abstract: A method for removing any single component or mixture of fats, oils and greases which have been added to or rendered out of an animal or vegetable product during cooking, thereby leaving the remaining commodity substantially fat-free without removing the water and water soluble flavor and nutrient salts. The product nearly instantaneously absorbs said fats, oils and greases onto a fabric substrate which is hydrophobic or repels water and oleophilic or attracts and absorbs hydrocarbons. The method works effectively on animal and vegetable fats, oils and greases through a temperature range from ambient or room temperature through boiling. The method removes fats, oils and greases from sauces, gravies, soups and any other cooking product regardless of type of cooking or type of fat, oil or grease and has the same removal effectiveness when used in waste treatment processes. The products are safe for use in microwaves.
