Abstract: A method of using repairing cracked or otherwise leaking polymer-modified asphalt-based containers for packaging asphalt. A strip of consumable adhesive tape is adhered to cover and seal the damaged portion of the container. Molten asphalt is then added to the repaired container. The molten asphalt is added to the container at a temperature that is below the melting temperature of the tape. Upon solidification of the asphalt in the repaired container, the entire asphalt package is melted prior to use in a melting apparatus, such as a gas-fired asphalt kettle melter. At the melter temperatures, the tape, container, and packaged asphalt melts or solubilizes in the melted mass.

Abstract: In a method of melting asphalt in a vessel, the molten asphalt normally emitting fumes, 0.2 weight percent to 6 weight percent of a polymer is added to the asphalt to reduce the visual opacity of the fumes by at least 25% over the same asphalt without the polymer. In another embodiment, the total emissions of benzene soluble suspended particulates is reduced by at least 15% over the same asphalt without the polymer. Preferably, the added polymer has a melt flow index of from 15 grams/10 minutes to 95 grams/10 minutes, and the added polymer reduces the visual opacity of the fumes by forming a skim on the upper surface of the molten asphalt.

Abstract: An insulation product includes an elongated comformable body of fibrous insulation having front and rear major surfaces and two elongated side surfaces. A facing is adhered to the front major surface of the conformable body, the facing having sufficient tensile strength to withstand a pressure, without tearing, of about 1.0 pound per square foot from the fibrous insulation in a wall cavity defined by wall studs, when the facing is adhered to the wall studs. The facing is bonded to the conformable body with sufficient strength to provide product integrity to the insulation product when it is cut lengthwise. The insulation product can be expanded when unconstrained to a high loft thickness so that when the batt is placed in an insulation cavity having a thickness less than or equal to the high loft thickness, the insulation product can be expanded to fill the insulation cavity. The fibrous insulation material has a resistance to compression less than about 1.

Abstract: A cam follower includes a radially inner arcuate bearing surface that matches the curvature of the outer surface of the cam. Engagement of this bearing surface with the surface of the cam opposes undesired motion of the cam follower, including motion radially away from the cam, about an axis perpendicular to the cam rotation axis, and/or about an axis parallel to the cam rotation axis. This arcuate engagement also facilitates effective lubrication of the cam follower. The cam housing is formed with arcuate bearing surfaces that define with the cam surface an annular cam follower cavity and that engage a radially outer arcuate bearing surface of the cam follower, maintaining the cam follower in position against the cam surface.

Abstract: A conformable insulation assembly is provided and includes a mineral fiber batt of a binderless fibrous material of substantially long fibers having low dimensional stability. The insulation assembly is capable of conforming and expanding its shape to an area into which it is installed better than prior art insulation assemblies.

Abstract: An extrusion system utilizes single or tandem extruders and a mixer-cooler to extrude a foamable extrudate through a die in a sealable chamber. The foamable extrudate is shaped and calibrated within the chamber. The die is mounted on the end of a gel tube projecting through a gland seal in a fixed bulkhead forming the upstream end of the chamber. The gel tube and mixer-cooler are mounted on a movable carriage, movement of which may be used to adjust the die with respect to shaping and calibrating equipment inside the chamber. The mixer-cooler achieves a selected narrow range of uniform viscosity of the melt at the die depending on the size of the product and density. The chamber is preferably a vacuum chamber producing low density foams. The product exits the chamber to atmosphere on a continuous basis through a submerged orifice in a water baffle immersion seal.

Abstract: A method of integrating organic fibers with mineral fibers includes centrifuging organic fibers from molten organic material, using a rotating organic fiber spinner, directing the organic fibers into a downwardly moving veil of organic fibers and gases, with the veil having an inwardly converging shape as it moves downward, centrifuging mineral fibers from molten mineral material using a rotary mineral fiber spinner positioned concentrically within the downwardly moving veil of organic fibers, directing the mineral fibers into a downwardly moving veil of mineral fibers and gases within the veil of organic fibers, wherein the veil of mineral fibers intersects with the veil of organic fibers to integrate the mineral fibers with the organic fibers, and collecting the integrated mineral fibers and organic fibers as a fibrous pack. An apparatus for performing the method is also disclosed.

Abstract: A roofing shingle includes organic, resinous material and an inorganic filler material, the single having a top surface, two side surfaces, an upper end, and a lower or butt end, defining a cavity on the underside of the shingle, with ribs positioned within the cavity. When applied to a roof, the shingle has the appearance of wooden shake shingle and provides a Class A fire barrier when tested according to ASTM test E108-93 for flame spread, burning brand and intermittent flame.

Abstract: A fire resistant thermosetting resin composite formulation comprising an effective amount of a flame suppressant additive. The thermosetting resin used in the formulation can be a polyester resin. The flame suppressant additive is a polyvinyl chloride powder which may be obtained as a reaction product of an emulsion polymerization, or alternatively, it may be obtained from recycled products containing significant amounts of polyvinyl chloride. The additive can be used in an amount of from 1% by weight to about 75% by weight based on the amount of an inorganic filler material that may be present in the formulation.

Abstract: A shock absorber assembly for a finish looper that reduces breaks of a asphalt-coated sheet. The finish looper includes a plurality of looper rolls forming a plurality of free hanging loops of the asphalt-coated sheet. The shocker absorber assembly is mounted on a frame structure capable of relative movement with respect to the looper rolls. The shock absorber assembly includes a plurality of rolls including an indexing roll, a guide roll, and a shock roll positioned between the indexing roll and the guide roll. Just prior to the last free hanging loop being completely payed out, the shock roll is in an up position and the indexing roll is in a down position. When the asphalt-coated sheet is further payed out, the asphalt-coated sheet engages the indexing roll and causes it to pivot from the down position to an up position. The weight and acceleration of the adjacent, upstream free hanging loop causes the shock roll to move from the up position to the down position.

Abstract: A consumable container is molded from a composition comprising 40 to 90 weight % of an asphalt and 10 to 60 weight % of a polymer material, which advantageously can include a first polymer such as PP that imparts heat resistance and a second polymer such as EVA that imparts toughness and impact resistance. This molded asphalt/polymer material preferably has an unnotched Izod impact strength of at least 2 joules. The container is consumable--it can be melted along with roofing asphalt held in the container without adversely affecting the properties of the asphalt and without requiring undue mixing. The composition also can be used to reduce fumes normally emitted from a kettle of molten asphalt, e.g., as measured by a reduction of the visual opacity of the fumes by at least 25%, a reduction of the hydrocarbon emissions of the fumes by at least 20%, or a reduction of the total suspended particulates emissions of the fumes by at least 15%. The container may be used, e.g.

Abstract: In a method for recovering vapors during the dispensing of a bituminous product into a tank, an inlet opening of the tank is closed with a fitting. The bituminous product is dispensed into the tank via the fitting. The bituminous product emits vapors inside the tank. The vapors are exhausted from the tank without direct contact of the vapors with moving parts. The vapors are transported to a condenser, and condensed to a liquid in the condenser. The condensed liquid is returned to the tank via the fitting.
