Abstract: Zirconium based granules are produced by the steps of forming an aqueous solution of a zirconium compound such as zirconium acetate, combining the aqueous solution with a phase stabilizer, and then heating the solution to evaporation at a temperature below about 180.degree. C. preferably below thereby forming amorphous zirconium based granules.In an alternate embodiment, an alcohol solution of a zirconium compound such as zirconium propoxide in propanol is acidified and hydrolyzed with water. The partially or fully hydrolyzed zirconium complex is mixed with a phase stabilizer to form a homogeneous solution. The solution is then subjected to evaporation at a temperature below about 180.degree. C. or below to form amorphous zirconium based granules.Zirconia fibers are produced by making aqueous solution of the amorphous zirconium based granules containing the phase stabilizer to the desired viscosity, fiberizing the solution, and finally converting the fibers under appropriate conditions.

Abstract: A latch mechanism adapted to lock a movable pull roll support to a fixed pull roll support in a mineral fiber attenuation apparatus. A latch arm is pivotally attached intermediate its length to the movable support and is spring biased into locking engagement with a latch seat on the fixed roll support. The latching surface of the latch arm and the mating surface of the latch seat are substantially perpendicular to a plane extending through the end of the latch seat and the pivotal attachment. This causes the latch to release upon relatively low pressure being applied to the opposite end of the latch arm.

Abstract: A low density high temperature resistant insulation material especially suitable for use in automotive turbine chambers which bonds well to metallic surfaces while being soft enough to remain bonded and reduce the stresses caused during thermal expansion. The inventive insulation material contains inorganic fiber; inorganic binder; hydrophilic particulate inorganic material; polymer; and preferably a setting agent and an opacifier.

Abstract: A high density moldable fiber glass material is disclosed. The glass fiber is coated with a powdered and liquid binder to form the material wherein the glass fiber is 45-90% and the binder is 10-45% by weight. The binder content is itself comprised of 25-50% of liquid binder and 50-75% of powdered binder.

Abstract: An article carrier which has an interior partition dividing the carrier in half. The partition is comprised of two unconnected face-to-face sheets of material, one being connected to a first top panel section at the center of the top panel and the other being connected to a second top panel section adjacent the first top panel section. The bottom and end panels contain weakened areas. When the weakened areas are separated the adjacent unconnected partition sheets become side panels in two smaller carriers. End panel flaps include weakened areas for allowing the end panels to separate when the carrier is broken down into two separate carriers.

Abstract: A paperboard tray for holding spaced rows of flat articles. A divider separating the rows includes sloped walls which, along with sloped wall portions in the side panels of the tray, serve to support the articles. A web connecting an outer end flap to a divider wall acts as a stop member to automatically position the end of the inner end flap as the overlapping flaps are moved into position during the formation of the tray from a blank.

Abstract: A carton adapted to receive rows of articles the bottoms of which are adjacent the side panels of the carton. A tear strip encircling the carton allows the carton to be separated into smaller display packages, each side panel of the carton forming the bottom panel of one of the separated packages. The tear strips in the top and bottom panels are aligned and preferably are at an angle to the side panels so that the front panels of the smaller display packages are low, enabling the first article in the smaller package to be on display. The end panels of the carton are formed of overlapping flaps which contain aligned tear strips. Tuck flaps allow side panel flaps to be connected to the end panels and to be folded in to form a double layer at the side edges.

Abstract: A wrap-around article carrier having end panels foldably connected to tuck flaps for holding the end panels in position. A center gradually triangular tuck flap is foldably connected to the top panel and to two generally triangular tuck flaps. The fold lines connecting the end tuck flaps to the center tuck flap contain cutouts, one edge of which comprises part of an edge of the center tuck flap and overlies the top of an article in the carrier to lock the tuck flaps and the end panels in place. The other cutout edge comprises part of an edge of the end tuck flaps and is positioned to contact the side of an article to stabilize the structure.

Abstract: A process for making a fibrous mat includes the steps of (a) combining (i) glass fibers, (ii) polyolefine fibers, (iii) fibers selected from the group consisting of polyamide fibers, polyester fibers, and mixtures thereof, and (iv) a cross-linked latex binder, (b) consolidating the fibers and binder into a loosely packed mat, (c) curing the consolidated mat at a temperature in the range of about 250-400 F., and (d) molding the cured mat into a desired shape at ambient temperature.

Abstract: A packaging machine for packaging containers such as bottles in a carton. Adjacent rows of bottles are conveyed downstream parallel to the downstream movement of spaced open-ended carton blanks. A separate conveying means in conjunction with stationary guides moves bottles diagonally downstream to the carton blanks. Wedge-shaped bottle separators are carried by the separate conveying means adjacent the carton blank moving means and engage adjacent bottles to separate the bottles into groups, which are then guided onto the blanks through the open ends thereof. The separators travel at the same speed as the carton blanks.

Abstract: An insulated window comprising a layer of insulation between two transparent sheets of glazing. The sheets are glued to the insulation layer and then separated so as to increase the thickness of the insulation, thereby providing a way to reduce the density of the insulation beyond the minimum density that can be manufactured. The light transmission of the insulation is substantially unaffected, but the thermal insulating value of the insulation is improved.

Abstract: An automotive headliner comprised of a laminate of double corrugated paperboard. Perforations in all the sheets of the laminate except the back paperboard sheet improve the acoustical performance of the liner. A vapor barrier on the back sheet prevents entry of moisture into the laminate from the roof, and a layer of sound dampening material on the front face of the laminate improves the sound absorption of the laminate. The front corrugation is larger than the back corrugation. When molding the laminate it is first moisturized, then heat molded. Heat is applied until the laminate has regained its rigidity.

Abstract: A wrap-around carton with overlapping flaps overlying a substantially flat surface of the packaged article. A tab on the outer flap extends into a slot in the inner flap, with shoulders formed from a slot in the outer flap engaging the edge of the slot in the inner flap to mechanically connect the flaps together. In addition, a tab on the inner flap is inserted into the slot in the outer flap, whereby the inner flap tab urges the shoulders down so as to hold the locking mechanism in place and the edge of the slot in the outer flap holds the inner flap tab in place.

Abstract: Plates mounted on support structure of a machine for packaging articles in sleeve-type carriers act as guides for the moving articles and as detectors of article jams which occur inside open sleeves prior to the closing of the end panel flaps of the sleeves. The plates are mounted for movement toward and away from the moving carrier sleeves and are biased inwardly toward the path of movement of the carrier sleeves. When a jam occurs the pressure of articles moving outwardly of the sleeve causes the plate to pivot away from contact with a sensor, thereby automatically shutting down the machine. The plate extends to the flap closing area so as to detect jams at any point between the loading station and the flap closing station.

Abstract: An expansion joint having a weather resistant cover and a fire barrier. The cover is a bellows attached to the upper surface of the adjacent joint structure by mounting flanges, and the barrier is a fire resistant inorganic fabric sheet mounted in the joint. The fabric supports resilient fire resistant inorganic fibrous insulation and is connected to the adjacent joint structure by mounting flanges. The flanges may be in the form of a bifurcated clamp, and one of the fabric-engaging clamp faces may be crimped and pierced to better grip the fabric.

Abstract: A method for forming composite webs. The method includes introducing alternative fibers during the fiber glass drum or sliver manufacturing process so as to produce a composite web, strand or roving.

Abstract: A carton having a bottom panel comprised of two overlapping flaps. The outer flap has a primary male tab engaging a primary female locking edge in the inner flap, while the inner flap has a secondary male locking tab engaging a secondary female locking opening in the outer flap. The secondary locking tab is connected to the carbon along a fold line coinciding with the fold line connecting the inner flap to the adjacent side panel, allowing a large secondary locking tab to be used even though the bottom panel is narrow. The outer and inner flaps are able to overlap across substantially the full width of the flaps to form a bottom panel of double thickness.

Abstract: An electric furnace for melting batch material and mixing the molten material. Electrodes are used to create what is believed to be electromagnetically stirred active melting areas within the molten material. The molten material is stirred by moving the electrodes and furnace shell with respect to each other while the electrodes are positioned in a corona discharge relationship to the melt. This can be implemented by rotating the electrodes or the shell or by a compound movement caused by moving the electrode support arms toward and away from the center of the vessel in timed relationship to pivotal movement of electrode support arms so as to cause the electrode tips to traverse an arcuate path concentric with the center of the vessel. In a shallow immersion, simple pivoting of the electrode support arms is beneficial. To further decrease the dead area within a furnace vessel utilizing electrodes which are shallowly immersed, the vessel can be made polygonal as opposed to circular in lateral cross section.
