Abstract: Methods for forming a lined brake shoe having a curved brake lining attached to a table of the lined brake shoe. The curved brake lining is manufactured by molding a flat sheet of brake lining material in a partially polymerized state. This flat sheet is allowed to cool prior to be positioned within a press having warmed dies. The warm dies of the press form the curved brake lining while holding the curved brake lining in its desired shape. The warm dies restart the polymerization process. When further polymerization has been completed the curved lining is removed from the press. One embodiment places the table of the lined brake shoe in the press. Then, by adding a bonding material, the completed lined brake shoe can be manufactured while the polymerization process continues in the press.

Abstract: Fused silica boules (19) having improved off-axis homogeneity are produced by controlling the air flow around the boule (19) during its formation. The boule is formed in a containment vessel (13) which collects soot from a plurality of burners (14). The containment vessel (13) rotates and oscillates relative to the burners (14) as the boule (19) is formed. Surrounding the containment vessel (13) is an air flow wall (130) which oscillates with the containment vessel (13). The air flow wall (130) is spaced from the containment vessel (13) by a gap (175) through which air flows during boule formation. The dimensions of this gap (175) remain constant as the boule is formed. Surrounding the air flow wall (130) is a stationary wall (160). The stationary wall (160) is spaced from the air flow wall (130) by a gap (165) whose dimensions change as the boule is formed. A motion accommodating seal (155) blocks air flow in this gap (165).

Abstract: Absorbent articles containing absorbent cores of fluff pulp frequently contain wrinkles in the absorbent core that run from side to side of the article, typically normal to the machine direction in the manufacturing process. Side-to-side wrinkles are deleterious in that they provide large flow channels for urine or other body fluids to escape to the edge of the article. Frequently, such wrinkles are present after manufacturing, before the article has been folded or worn. The cause of the wrinkles is believed to be due to natural instabilities during compression of the fluff pad shortly after it is formed. Means for reducing cross-directional wrinkles include the use of grooved, drilled, or patterned compression rolls to densify the fluff pulp while providing opportunities for reduced in-plane displacement during compression or, if in-plane displacement does occur, providing paths for cross-directional displacement as well as machine-direction displacement so that continuous CD wrinkles cannot form.

Abstract: The method and apparatus for making a preform which is a rigid shaped item formed of glass fibers rigidly joined to each other where adjacent fibers touch. The interstices between the fibers are unfilled for the use of matrix resin to subsequently form a molded article. The preform is formed by shaping fibers into the preform shape, applying a binder to the fibers so that they are coated at the locations where they touch. The binder is sensitive or responds to the application of electromagnetic energy. In completing the preform after the application of the binder, the preform is subjected to electromagnetic energy so that the binder hardens to form a rigid preform. In one species form, the electromagnetic energy is applied in the form of microwave energy. The application of electromagnetic energy causes a reaction in the binder without requiring heating of the glass fibers so that the preforms can be rigidified rapidly and efficiently.
