Abstract: A bushing plate for use in the production of glass fibers has an array of nozzle tips. The bushing plate is formed by successive cold forming operations from a starting plate of precious metal alloy. The starting plate is first indexed through a press which coins embossments raised from one side of the plate. The plate is then indexed through another press in which bores are extruded through the embossments to form the nozzle tips. The ends of the tips are then finished in an operation such as EDM wire finishing.

Abstract: A process for introducing additive particles to extruded fibers during production of the fibers. Particles are directed into a moving stream of fibers during or after the fiber attenuation process. The movement of the fibers intermingles the particles with the fibers prior to the intermingled material being collected on a moving support. If liquid binder is sprayed onto the fibers it is subsequently set in an oven to bind the fibers and the particles to each other. The fibers preferably are mineral fibers and the particles may be fibers or particles introduced for a variety of reasons, such as to increase the strength of the product or to serve as extenders or fillers.

Abstract: A hexagonal basket-style carrier formed from a unitary blank. Each side panel is connected to a triangular bottom panel section forming a segment of the bottom panel of the carrier. The bottom panel sections are connected by triangular tuck panels having folds which extend up into the interior of the carrier on opposite sides of the handle to divide the carrier into cells. Tabs on the ends of the handle are connected with slots in the carrier to hold the handle and bottom panel in place.

Abstract: An industrial luminaire assembly having an electrical assembly and an optical assembly pivotally mounted and latched thereto for quick installation and removal. The optical assembly also providing for compression of its glass prismatic reflector to strengthen it, and including a bottom closure pivotally mounted to provide access to the interior of the optical assembly for relamping.

Abstract: An enclosed carrier having spaced handle openings in the top panel. The top panel is formed from two overlapping flaps, each of which has a folded-over edge portion adhered to itself. The folded-over edge portions overlie each other to form the strap portion of the handle extending between the handle openings, with the folds of the edge portions being aligned with the inner edges of the handle openings. In one embodiment the handle strap comprises a four-ply layer and in another embodiment it comprises a three-ply layer. The folded-over edge portions of the top flaps may be weakened at their intersection with the fold lines of end panel flaps to enable the end panel flaps to be readily folded into place.

Abstract: The reinforcing wires in a fibrous duct are inserted by simultaneously piercing opposite sides of the duct with elongated piercing means mounted on a reciprocally movable frame. The piercing means may be the reinforcing wires themselves or may be separate structure, such as tubes, which can function as guides for the insertion of the wire before they are withdrawn.

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 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 by heat to form amorphous zirconium based granules.Zirconia fibers are produced by making aqueous solutions 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: Apparatus for placing a coupon or other small sheet onto a predetermined location of moving substrate, such as a carton blank. A coupon supply hooper and a glue station are radially spaced about the path of rotation of vacuum gripping heads mounted on opposite ends of a rotating support arm. The gripping heads are fixed to shafts which are caused to rotate by planetary gears. The gear movement causes the gripping heads to be fully extended when they reach the hopper, the glue station and the moving substrate and to have a composite angular motion enabling the entire bottom surface of the coupon to be parallel to the substrate when the coupon contacts the substrate.

Abstract: A sleeve-type article carrier and a blank for forming the same. The end panels of the carrier comprise overlapping end flaps which overlie dust flaps such that a single stripe of adhesive can be used to adhere the overlapping end flap to the overlapped end flap and to the underlying dust flaps. The end flaps and dust flaps are dimensioned so that the blank can be die cut from a web of no greater width than is used in producing blanks of conventional design.

Abstract: Integral retaining means in an open-ended wrap-around carrier for preventing the spaced bottom portions of articles such as tapered tubs from engaging each other and escaping the carrier through the open end. The bottom panel is comprised of inner and outer mechanically connected flaps. The outer bottom panel flap contains a retainer flap at each end connected along a fold line overlying the inner edge of an opening in the inner bottom panel flap. The retainer flaps extend up into the interior of the carrier through the openings in the inner bottom panel flap, and include spaced converging fold lines which create angled side walls for engaging the bottom portions of the articles.

Abstract: A carrier for articles such as beverage cans of the type that grip the top portions of the cans so as to suspend them from the carrier. The upper ends of the cans extend through apertures in the bottom panel of the carrier, and the chimes or lips of the cans are engaged by locking tabs surrounding the aperture. Glue flaps foldably connected to the bottom panel adjacent the can apertures by connecting flap segments overlie the upper ends of the cans. The connecting flap segments contain support tabs which assist in supporting the cans, thereby providing support substantially throughout the circumference of the cans.

Abstract: A method and apparatus for expanding the fiber column produced by a rotary fiber glass manufacturing unit. A rotating bell-shaped shell is mounted beneath the rotary disc of the manufacturing unit so that the lower portion of the shell is in the path of the fiber column, causing the column to be outwardly deflected. Water is directed on the inner surface of the shell to cool the shell in order to prevent curing of binder which comes in contact with the shell, and binder is applied below the point of water application. If an amount of water in excess of the amount needed to cool the shell is provided it is thrown outward in the form of a spray which wets the fibers. The water spray also prevents fiber and binder from accumulating on the bottom edge of the shell.

Abstract: A method and apparatus for encapsulating a porous article in plastic film without employing supporting molds. The article is deposited onto a lower web and an upper web is moved into overlying position. The edges of the webs are gripped by moving teeth to move the webs and the article in unison. The webs are then pinched together adjacent the article to form an enclosed volume. The film is heated to its fusing temperature and the enclosed volume is evacuated through a tube inserted through the lower web and into the article. The tube is removed and the fused webs are trimmed adjacent the edges of the article, resulting in an encapsulated article.

Abstract: Integral retaining means in an open-ended wrap-around carrier for preventing articles such as bottles from escaping the carrier through the open end. The bottom panel is comprised of inner and outer mechanically connected flaps. The outer bottom panel flap contains a retainer flap at each end connected along a fold line which is generally parallel to the open end edge of the bottom panel. The retainer flaps extend up into the interior of the carrier through openings in the inner bottom panel flap. The retainer flap is folded along converging fold lines so that it forms a retainer finger engaging the outer portions of the end bottles in two adjacent rows of bottles in the carrier.

Abstract: Insulating the exhaust pipe of an internal combustion exhaust system by sliding a flexible insulated tube over the exhaust pipe. The tube comprises concentrically arranged inner and outer corrugated stainless steel tubes, with the annulus between the corrugated tubes filled with refractory fiber insulation. The wall thickness of the corrugated tubes is in the range of 0.002 inch and 0.004 inch, which provides the insulated tube with sufficient flexibility to be trained over the angled portions of the exhaust pipe. The contact between the corrugations and the pipe assists in holding the insulated tube in place. The inner tube may extend beyond the outer tube and be flared back to the outer tube to enclose the insulation and facilitate movement of the insulated tube over the exhaust pipe. Alternatively, the insulation may also be sealed by end caps.

Abstract: A modified glue flap of a folding carton blank for preventing glue from being squeezed out during the step of adhering the glue flap to the opposite end panel. The face of the glue flap engaged by the glue back-up wheel includes a protrusion near the trailing edge of the flap. Engagement of the protrusion by the back-up wheel causes the glue wheel to skip the trailing area of the flap. The absence of glue in this area prevents glue from being squeezed out when sealing pressure is subsequently applied to the glue flap and the opposite end panel. The protrusion may take the form of an embossed ridge, forming a channel on the opposite side of the protrusion for receiving any excess glue which would have been squeezed out.

Abstract: An article carrier having handle openings in the end panels. Handle openings are provided in end panel flaps connected to the top panel. The end panel flaps overlie a second layer of material also containing handle openings so that the handle openings in the end panel flaps are aligned with the handle openings in the second layer, thus providing handle openings of double thickness. The second layer may be a flap connected to an inner top panel layer underlying the top panel or it may comprise end panel flaps connected to the side panels.

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 fiber glass board useful as a form board for lightweight cement and the like is strengthened by providing for the fibers to be predominantly oriented generally parallel to the major faces of the board in directions both parallel to and transversely of the dimension of the board corresponding to the process direction. A downstream conveyor which moves the blanket of fibers through the curing oven moves faster than the collection conveyor, thereby producing a drawing effect on the blanket and causing the desired fiber alignment. A glass fiber mat is applied to one or both major faces of the blanket prior to movement through the oven to provide additional stiffness to the board.
