Abstract: A multi-layered web is disclosed that is resilient and/or elastic in the Z-direction. Thus, when the web is compressed, the web assumes a compacted state and then expands to an expanded state when the compressive forces are removed. In one embodiment, the multi-layered web includes a middle layer made from a resilient blend of fibers positioned inbetween two outer layers. The middle layer, for instance, can contain elastomeric fibers, three-dimensional fibers, and/or debonded fibers.

Abstract: A system comprising a pulper configured to (i) accept surfactant, a liquid and fiber stock and (ii) generate a foam that suspends the fiber stock, wherein the foam has a half-life; a headbox configured to receive the foam-suspended fiber stock from the pulper and displace the foam-suspended fiber stock onto a forming wire, wherein a time it takes the foam-suspended fiber stock to move from the pulper to the headbox is less than the half-life; and a foam return device that removes at least some of the foam from the forming wire and returns the at least some of the foam to the pulper.

Abstract: The invention comprises a system for cooling a component in a gas turbine engine, and, in particular, for cooling an engine electronic control thereof. The cooling system includes a housing for mounting the control having a plurality of heat transfer fins extending outwardly therefrom. The housing is mounted in the engine upstream of a compressor and to a front frame having an aperture through which the fins extend. The front frame defines a flowpath to the compressor and the fins extend into the flowpath without adversely affecting the aerodynamic airflow pattern thereof. In a preferred embodiment, the fins extend substantially only to an inner surface of the front frame, and the housing includes temperature and pressure sensors disposed below root sections of the fins.
