Abstract: A method and apparatus using pneumatic pressure and reduced, controlled clamping pressure to provide reliable, high speed pneumatic forming of thin foil workpieces at ambient temperatures without lubricants or cull plates. Forming elements are provided which incorporate a combination of surfaces and features which enable the reduced, controlled net clamping pressures for forming thin foil workpieces, and control of material slip during forming. Thin foil workpieces formed therewith have reduced incidence of tearing and wrinkling of the foil material. The method is capable of fast cycle times and produces minimal waste.

Abstract: A glass fiber insulation product includes irregularly-shaped glass fibers of two different glasses having differing coefficients of thermal expansion, with the irregularly-shaped dual-glass fibers exhibiting a substantially uniform volume filling nature, and providing improved recovery and thermal conductivity abilities even in the absence of a binder material.

Abstract: A multiple conformable insulation assembly is provided and includes at least two mineral fiber batts of a binderless fibrous material of substantially long fibers interconnected to one another. Interconnection allows for the simultaneous installation of multiple batts. 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. The batts are preferably interconnected through the use of a support layer.

Abstract: This development relates to elastomer modified polyester for sheet molding compound (SMC). This development copolymerizes the rubber with the polyester. The reaction provides copolymers with extended storage times without phase separation. It also enhances impact resistance of the molded part.

Abstract: A method for fiberizing mineral material with organic material includes centrifuging mineral fibers from molten mineral material with a first rotating spinner, changing the direction of the mineral fibers to form a downwardly moving veil of mineral fibers, establishing a flow of molten organic material moving toward a second rotating spinner positioned within the veil, dividing the flow of molten organic material into a plurality of streams, directing, by means of conduits, individual ones of the plurality of streams toward the peripheral wall of the second rotating spinner, the conduits shielding the molten organic material from heat from the first rotating spinner, and centrifuging organic fibers from the molten organic material.

Abstract: A method for fiberizing mineral material with organic material includes centrifuging mineral fibers from molten mineral material with a first spinner rotating about an axis, changing the direction of the mineral fibers to form a downwardly moving veil of mineral fibers, establishing a flow of molten organic material moving downwardly in a first conduit positioned within the veil, and directing the flow of molten organic material to a position beneath the spinner, dividing the flow of molten organic material into a plurality of streams, directing, by means of individual conduits, individual ones of the plurality of streams radially outwardly away from the first conduit, rotating the individual conduits about the axis, centrifuging organic fibers from the molten organic material by means of nozzles at the radially outward ends of the individual conduits, and directing the organic fibers into contact with the veil of mineral fibers.

Abstract: Fiberizable glass composition with increased levels of BaO are suitable for insulation. These glasses have physical properties which allow current processes to fabricate them into insulation. The glasses also meet proposed German regulations regarding KI.gtoreq.40.

Abstract: Fiberizable glass composition with increased levels of B.sub.2 O.sub.3 and Na.sub.2 O are suitable for insulation. Coupled with alumina levels as high as possible, these glasses have improved durability. Moreover, these glasses have physical properties which allow current processes to fabricate them into insulation. The glasses also meet proposed German regulations regarding Kl.gtoreq.40.

Abstract: A method for applying granules to a coated sheet, and in particular a coated asphaltic sheet for use in the manufacture of roofing, comprises controlling a fluid (e.g., pneumatic) counterflow through the discharge opening of a nozzle which holds an accumulation of granules therein to rapidly stop or otherwise modify the flow rate of granules onto the sheet. A buffer chamber is in communication with the granule accumulation in the nozzle, and an apparatus modifies the pressure in the buffer chamber to generate the desired fluid flow through the nozzle opening. A vacuum source provides a negative pressure for a pneumatic counterflow, and a positive pressure source is utilized to increase pressure in the buffer chamber to act as a discharge assistant.

Abstract: A retainer clip for use with concrete form tie for retention of reinforcing rods has a one-piece body which includes a header, and first and second clips extending angularly therefrom, spaced apart in a first direction, and defining therebetween a generally u-shaped opening sized to slidably receive a reinforcing rod of generally circular cross section. Each of the clips include first and second prongs spaced apart in directions lateral to the first direction, and at least two prongs of the clips further define therebetween a narrow generally rectangular passage which intersects at least a portion of the u-shaped opening, and is sized to receive at least a notched form tie of generally narrow rectangular cross section. The retainer clip secures the reinforcing rod in position substantially against the form tie in a notch to inhibit both relative motion in the first direction and substantial separation therebetween.
