Abstract: An absorbent article includes an outer cover member, a liner, and an absorbent body structure disposed between the cover member and the liner. A first matrix of discrete deposits of a skin wellness lotion formulation are applied relative to the body facing surface of the liner so as to contact the wearer's skin. The lotion formulation deposits have a phase-change temperature less than body temperature. A second matrix of discrete deposits of a phase-change liquid are applied to the body facing surface of the liner interspaced with the lotion deposits. These phase-change liquid deposits have a phase-change temperature greater than body temperature. The phase-change lotion deposits have a height above the body facing surface greater than the height of the phase-change liquid deposits.

Abstract: An ultrasonically enhanced continuous flow apparatus for selectively microemulsifying water and other normally immiscible fluids into the fuel of continuous combustors at the point of injection and a method for the same is disclosed. The apparatus includes an injector housing which in part defines a chamber adapted to receive a pressurized liquid and a means for applying ultrasonic energy to a portion of the pressurized liquid. The injector housing further includes an inlet adapted to supply the chamber with the pressurized liquid, and an exit orifice defined by the walls of an injector tip. The exit orifice is adapted to receive the pressurized liquid from the chamber via a vestibular cavity and pass the liquid out of the injector housing in the form of an emulsified, atomized plume. When the means for applying ultrasonic energy is excited, it applies ultrasonic energy to the pressurized liquid without mechanically vibrating the injector tip.

Abstract: An ultrasonically enhanced continuous flow apparatus for injection of liquid fuel into a continuous fuel combustor and a method of improving continuous flow fuel combustors by the application of ultrasonic energy to a pressurized liquid fuel exiting an orifice is disclosed.

Abstract: A compressed adsorbent filter cake for removing caffeine from liquids. The filter cake is composed of a compressed matrix of fibrous material; and adsorbent particulate material integrated within the compressed matrix of fibrous material, so that passage of a liquid having a caffeine concentration ranging from about 20 to about 100 mg per 100 mL of liquid through the matrix for a contact time of less than about 2 minutes results in at least a 40 percent reduction in the caffeine concentration of the liquid. The compressed matrix of fibrous material may a compressed wet-laid fibrous mat. The adsorbent material may be selected from clay minerals and zeolites. Generally speaking, the filter can be adapted to provide at least a 40 percent reduction in the caffeine concentration for about 1 cup to about 40 cups of a liquid.

Abstract: The present invention is directed toward a water vapor responsive self sealing thin film which is formed from a blend of at least about 75 weight percent of a water dispersible polymer; from about 0.5 to about 5 weight percent of a xerogellant; and from about 7.5 to about 20 weight percent of a plasticizing agent.

Abstract: A thin soft film material having fibers and/or particulates embedded therein is disclosed. A process for effecting such embedding utilizing hydrosonics is also disclosed.

Abstract: Disclosed is a hydrodisintegratable material which, when injection molded into an object, acquires and maintains the desired shape without becoming brittle. Additionally, in the presence of water, the molded object has the ability to rapidly disintegrate and disperse when subjected to standardized agitation testing. The moldable material typically includes: (1) from about 7.5 to about 85 weight percent of at least one water dispersible polymer; (2) from about 7.

Abstract: Disclosed are a number of processes for forming a liquid-impermeable sheet having a fibrous cloth-like surface. In one embodiment the process includes the steps of: (1) forming a sheet having first and second fibrous surfaces; and subjecting the sheet to pressure and a z-gradient temperature differential sufficient to melt the fibers of the first surface and form the melt into a liquid impermeable skin without significantly altering the fibers of the second surface.

Abstract: A method for forming thinned areas in a thin sheet material. The method includes the steps of (1) placing the thin sheet material on a pattern anvil having a pattern of raised areas wherein the height of the raised areas is generally less than the thickness of the sheet material; (2) conveying the sheet material, while placed on the pattern anvil, through an area where a fluid is applied to the sheet material; and (3) subjecting the sheet material to a sufficient amount of ultrasonic vibrations in the area where the fluid is applied to the sheet material to area thin the sheet material in a pattern generally the same as the pattern of raised areas on the pattern anvil. In some embodiments, the thinned areas may be micro areas.
