Abstract: An absorbent article has a topsheet, an absorbent core, and an acquisition distribution layer between the topsheet and the core. The topsheet has an affinity for water and is therefore philic, not phobic. The acquisition distribution layer is more philic than the topsheet, thereby creating a surface energy gradient between the topsheet and the acquisition distribution layer.

Abstract: The invention relates to an absorbent article having a topsheet and an absorbent core material. An acquisition distribution layer (ADL) is located between the topsheet and the absorbent core material. By employing a high void volume acquisition distribution layer the absorbent article can achieve greater strikethrough and rewet characteristics without altering the core design, or the absorbent article may achieve current design criteria with less absorbent core material or less expensive absorbent core material. A method is disclosed for designing an absorbent article to reduce the bulk of the absorbent core. Furthermore, a method is disclosed for reducing the cost of an absorbent article by using a high void volume ADL along with less expensive core materials, while maintaining the strikethrough and rewet performance of the absorbent article.

Abstract: A flying vehicle having a pair of counter rotating propeller blades which provide lift for the vehicle when the vehicle is in a flight mode of operation. The counter rotating blades have in flight adjustable pitch and are connected to a control and steering system in the cockpit of the vehicle. A gas turbine engine located in the aft section of the vehicle is connected through a drive shaft and transmission to the counter rotating propeller blades When the vehicle transitions to the flight mode, the user has aircraft controls available in the cockpit to make the transitions from a driver to a pilot in a short time period. Yaw pedals located on the floor board of the cockpit as well as a pitch control handle and the steering wheel allow the user to steer and control the altitude of the vehicle when the vehicle is in the flight mode.

Abstract: A process for the manufacture of a vapor permeable, liquid impermeable composite material comprising a three-dimensional apertured substrate having a vapor permeable, liquid impermeable coating material thereon, the substantially liquid impervious composite material, and an apparatus for making the composite material are disclosed. Successive portions of a continuous sheet of an apertured substrate are passed into contact with a continuous moving perforated member. The coating material is supplied onto the substrate. The coated substrate is subjected to a vacuum which causes the coating material to flow onto the substrate material and in certain embodiments, at least partially into the apertures in the substrate. The vacuum is maintained for a period of time sufficient for the coating material to adhere to the substrate. The coated portions of the substrate are continuously removed from the moving member.

Abstract: A process for the manufacture of apertured, three-dimensional substrates having an extrusion coating material thereon, the coated substrate and an apparatus for making the coated substrate are disclosed. Successive portions of a continuous sheet of the apertured substrate which has a top surface and a bottom surface are passed into contact with a continuous moving perforated member. The coating material is supplied onto the top surface of the continuous moving substrate. The bottom surface of the substrate is subjected to a vacuum. The vacuum causes the coating material to flow onto the top surface of the substrate material and in certain embodiments, at least partially into the apertures in the substrate. The vacuum is maintained for a period of time sufficient for the coating material to bond to the substrate. The coated portions of the substrate are continuously removed from the moving member.
