    摘要： An improved internal wetting agent is provided for blending with polymeric material, with the formation of apertured films and/or polymeric fibrous webs contemplated. Films and/or nonwoven fabrics of this nature are suited for use in disposable absorbent articles, particularly for the so-called topsheet or facing layer, which contacts the wearer during use. Because polymeric materials from which these types of facing layers are made are typically hydrophobic, the provision of an internal wetting agent facilitates the passage of liquid through the facing layer into an associated absorbent structure.

    摘要： The present invention generally relates to an apertured or reticulated film, and more specifically, the present invention relates to a method of imparting one or more raised elements into a previously apertured or reticulated film utilizing a forming surface. A forming apparatus can accept an apertured film, preferably but not limited to a thermoplastic composition, and impart one or more raised continuous or discontinuous profiled elements into the surface of the apertured film by exposing the apertured film to an air stream having an elevated temperature (such as by exposure of the air stream to direct contact with a heating element). The heated air stream affects the apertured film by inducing the film to deflect onto profiled elements defined in the forming surface of the forming apparatus.

    摘要： A method for replacing a damaged brake beam on a railcar having a car body supported on a railcar truck. The railcar truck includes a wheel and axle assembly mounted between a pair of laterally spaced side frames. The side frames include structure, on an inboard side thereof, for guiding and supporting the brake beam, and with the structure on the side frame members defining a predetermined lateral distance therebetween. The method comprises the steps of: removing the damaged brake beam from between the side frames of the railcar truck; arranging a first part of a replacement brake beam structure into supported and guided relation with the brake beam guide on the first side frame, with the first part of the brake beam structure having an operative length shorter than the predetermined distance between the brake beam guides on the first and second side frames; arranging a second part of the replacement brake beam structure into supported and guided relation with the brake beam guide on the second of the side frames, with the second part of the brake beam structure having an operative length shorter than the predetermined distance between the brake beam guides on the first and second side frames; securing the first and second parts of the replacement brake beam structure to each other to form a rigid assembly capable of withstanding the braking forces applied thereto during operation of the railcar and with the combined operative lengths of the first and second parts of the replacement brake beam structure being substantially equivalent to the predetermined distance between the brake beam guides on the first and second side frames; and providing a brake head in operable combination with each of the first and second parts of the replacement brake beam structure for movements toward and away from the wheels as the first and second parts forming the rigid assembly move within the brake beam guides on the side frames.
