摘要:
The invention relates to asphalt emulsions comprising an asphalt component selected from the group consisting of a solvent extracted asphalt, an oxidized asphalt, and combinations thereof. The invention also relates to products made therefrom, including fibrous mats comprising a fiber component, such as glass fibers, and a binder component comprising an asphalt emulsion. The invention further relates to wet-laid processes for manufacturing fibrous mats and that employ the use of an amphoteric surfactant, which is applied to a wet fiber web prepared from a dispersion of fiber components, such as glass fibers.

摘要:
The subject invention provides a method for producing essentially homogeneous asphalt compositions which are comprised of the asphalt, a block copolymer (such as a linear block copolymer or a radial block copolymer), and one or more additional desired additives. This method offers the advantage of being capable of attaining the essentially homogeneous asphalt composition in one pass procedure with a short residence time in the mixing equipment. This greatly reduces the thermal history to which heat sensitive asphalt additives, such as asphalt modification polymers, are exposed. It also simplifies the mixing procedure and can reduce the overall amount of energy required to attain the desired blend. In some case, it allows for the production on a commercial basis of asphalt compositions which would otherwise not be feasible, for instance the production of asphalt compositions which contain high levels of asphalt modifications polymers which are otherwise difficult to process.

A roofing product used in commercial built-up roofs includes a roll roofing sheet having a backing film adhered to one side thereof, the backing film being miscible with an adherent substance when the roofing sheet is unrolled and applied to a roof using the adherent substance. Prior to the unrolling of the roofing sheet, the backing film inhibits the transfer of material to an opposite side of the roofing sheet.

A high speed granule delivery system and method is disclosed for dispensing granules in intermittent patterns onto a moving asphalt coated strip in the manufacture of roofing shingles. The system includes a granule hopper and a rotationally indexable pocket wheel in the bottom of the hopper. A series of pockets are formed in the circumference of the wheel and the pockets are separated by raised lands. A seal on the bottom of the hopper seals against the raised lands as the wheel is indexed. In use, the pockets of the pocket wheel drive through and are filled with granules in the bottom of the hopper. As each pocket is indexed beyond the seal, it is exposed to the moving asphalt coated strip below and its granules fall onto the strip to be embedded in the hot tacky asphalt. Well defined patterns of granules are possible at high production rates.

A system of the present invention for applying a substance to an applied area includes a patch (11), as well as apparatus (12, 14, 16, 18 and 21) and methods for making the same. The patch includes backing material (52) and a tri-laminate (54), with a dose of medication sealed therebetween in reservoir (62). To facilitate and increase transdermal and/or topical application of the medication to the applied area, such as the skin of a user, the tri-laminate includes a layer material (68) having at least one opening therein (64), which permits the medication to flow through each opening without tearing or ripping the layer of material covering the reservoir.

Disclosed painted roof coverings and related methods of manufacturing such painted roof coverings that use a color coating over the roof coverings instead of embedded pre-colored rock granules on the exposed surface of the roof coverings. By painting a roof covering with a color coating, any kind of top surfacing material, such as rock, plastic, mineral, man-made, or organic granules, may be used in place of the pre-colored rock granules. In some embodiments, it is desirable to size the top surfacing material to provide adequate UV protection and coverage to the weatherproofing asphalt material located below the top surfacing material. Further, the color of the shingles may be accurately matched between batches of shingles, between manufacturing facilities, and even between manufacturers. In addition, designs may be painted on the surface of the roof covering, which was previously impossible using pre-colored granules.
摘要:
A system of the present invention includes a tandem package and an apparatus and method for making the same. The tandem package includes a strip of film material having a plurality of medicament containing compartments. To prevent ripping or exposure of the medicament in an adjacent compartment upon opening of an individual segment of the package, each compartment is separated by a dividing member. In addition, to facilitate opening of the each segment while providing increased resistance to opening by children, each segment includes a pinhole in at least one corner of the segment perpendicular to a fold line. Thus to open the segment to expose the medicament, the corner may be folded along the fold line and torn at the pinhole, with the dividing member limiting tearing of the film. The apparatus and method of the present invention include a number of sub-assemblies for sealing the film, forming the compartments, placing the dividing member between the compartments, placing the dose of medicament in each compartment and cutting the continuous web into strips having the desired number of segments therein.
