  • Patent number: 8658852
    Abstract: The present disclosure relates to disposable absorbent articles including a topsheet; a backsheet; a liquid acquisition layer; and a substantially cellulose free absorbent core; wherein the liquid acquisition layer and the absorbent core are located between the topsheet and the backsheet; wherein the topsheet and liquid acquisition layer include corresponding discrete indented regions and unindented regions. The liquid acquisition layer comprises a first density, D1, below the unindented regions of the topsheet and comprises a second density, D2, below the discrete indented regions of the topsheet.

  • Patent number: 8603277
    Abstract: Aspects of the methods herein relate to the fabrication of absorbent articles wherein a continuous topsheet web is advanced in a machine direction. A liquid acquisition layer and an absorbent core are combined with the continuous topsheet web. The combined continuous topsheet web, liquid acquisition layer, and absorbent core advance through the embossing nip to emboss a pattern in the continuous topsheet web. As the combined continuous topsheet web, liquid acquisition layer, and absorbent core advance through the embossing nip, the rotating patterned embossing roll contacts the continuous topsheet web. And the rotating anvil roll contacts the absorbent core. By advancing the topsheet together with the acquisition layer and absorbent core through the embossing nip, a relatively deep pattern can be embossed into the topsheet than otherwise might be possible when embossing relatively thin topsheet web materials.

  • Patent number: 6489043
    Abstract: An iron aluminide fuel injector component such as a nozzle, plunger or other part is manufactured from iron aluminide or includes an iron aluminide coating on at least a portion of a surface in contact with the fuel which passes through the fuel injector. The iron aluminide alloy can include 8 to 32 wt. % Al, up to 5 wt. % refractory metal, B and/or C in amounts sufficient to form borides and/or carbides. The fuel injector component can be formed from powders of the iron aluminide alloy by powder metallurgy techniques and the coating can be formed by a diffusional reaction process, cathodic plasma process, chemical vapor deposition or physical vapor deposition. The fuel injector component is corrosion, carburization, sulfidation and/or coking resistant.
