Abstract: There is disclosed herein in a preferred embodiment a fibrous body which includes at least two layers of strands of continuous filaments and binder particles in each layer. One of the layers has filaments of the strands therein at least partially dispersed to form a mesh size which entraps binder particles therein which have a mesh size larger than the mesh size of the dispersed filament layer, as well as smaller size particles lodged at intersections and crossovers. Another lever has strands which form a mesh size which do not necessarily entrap binder particles but may retain particles therein at interstices of strands. The fibrous body has a binder content in the dispersed filament layer which is larger per unit volume than the binder content in the other layer. There is also disclosed a method for producing a fibrous body having variable mesh sizes or characteristics by selectively filamentizing strands or a layer of strands already in place in a mat-like collection of strands.

Abstract: A fiberizer with an ignition system is provided. The fiberizer includes an annular combustion chamber with a downwardly directed annular slot positioned to direct the hot products of combustion toward a fiber spinner. The fiberizer has a plurality of radiant cup burners disposed uniformly therearound in an upper portion of the chamber. An ignition burner is located between two of the radiant cup burners and directs a long ignition flame therebetween. The ignition system includes a spark plug for igniting an air-gas mixture in an end of the ignition burner and controls are designed to supply the air-gas mixture to the burner and to provide a spark for the spark plug simultaneously.

Abstract: The present invention proposes a method of and appratus for making a mat of continuous strands of glass fibers or the like wherein each strand comprises a large number of individual filaments. The strands are deposited in mat form on a collection surface and are flooded with liquid to disperse individual filaments in the overall strand orientation. The flooded filaments are then conveyed to a drainage zone. As they are conveyed, the filaments pass through successive turbulent liquid regions wherein the filaments are locally deflected both counter-current to and con-current with the direction of conveyance, yet the general or overall strand orientation is retained. As a result, the transverse strength of the final mat is materially increased, and the mat has a multitude of fine, controllable interstices as required for some uses, e.g., asphalt-impregnated roofing mat.

Abstract: A sizing for glass fibers, comprising water dispersible epoxy resin, polyvinyl acetate copolymer, vinyl ethylene copolymer, an organosilane, wax, lubricant, and a fluid silicone emulsion is provided, whereby the sized fibers in the form of strands, possess excellent integrity and whiteness in color when incorporated into a resinous matrix.

Abstract: In a molding process wherein a press delivers molded parts alternately to two or more stations, an apparatus is provided for moving a part from any one of the alternate press unloading stations to a common receiving station. The apparatus moves the part along a curvilinear path while maintaining the orientation of the part constant with respect to the receiving station. The apparatus includes a carriage which is supported on an overhead track, and which itself supports a rotatable holder. The apparatus further includes mechanical means capable of rotating the holder in response to the change in angular orientation of the carriage as it moves along the curved track, to effect the controlled orientation of the part as desired.

Abstract: A cobalt-base alloy, particularly suitable for high temperature molten glass environments, and articles manufactured from the alloy, preferably by casting, are disclosed.

Abstract: Polyurethane and polyisocyanurate-urethane foams are disclosed. Organosulfur compounds are added to the foams to reduce their smoking under fire conditions.

Abstract: Apparatus for increasing the rate of evaporation of liquid from wound linear material, such as glass strand, by subjecting successive outer layers of the package to an air jet.

Abstract: A composition for use in the treatment of glass fibers for use as reinforcement for plastics and elastomeric materials and glass fibers treated therewith in which the composition is formulated to include the reaction product of a silicon halide such as silicon tetrachloride with an aliphatic epoxide containing at least fourteen carbon atoms.

Abstract: Apparatus for and the method of producing a sliver-like fibrous product including forming glass fibers, conveying the glass fibers in a body of gas and depositing them on the porous rim of a rotating wheel to form a coherent web, advancing the porous rim with the web thereon over an opening having a progressively reducing size in the direction of rim movement, establishing a zone of reduced pressure within the wheel to draw air through the fibers into the opening to progressively condense the web into a loosely associated longitudinal coherent sliver-like grouping of fibers, and discharging the longitudinal sliver-like fiber grouping from the rim.

Abstract: A binder composition for use in the manufacture of wool-like and board-like masses of intermeshed, randomly oriented vitreous fibers comprising a thermo setting phenolic resin and an organo silicon component in the form of a metal salt of an organo silane.

Abstract: Organo metallic compounds for use in the treatment of glass fibers prepared by reaction of a hydrolyzable metal halide and one or more epoxides. The organo metallic compounds of this invention are characterized by a beta-haloalkoxy group and are resistant to hydrolysis.

Abstract: This invention is addressed to organo silicon compounds prepared by reaction of a halosilane, a monoepoxide containing at least one other functional group, and at least one polyepoxide. The products of this invention are liquid organo silicon compounds which are useful in the treatment of glass fibers to improve the bonding relationship between glass fibers and resinous or elastomeric materials.
