摘要： A breathable elastic laminate is formed by bonding a film including an elastic water vapor-soluble polymer to a neckable nonwoven web such that when the film is relaxed, the web is in a necked state. The breathable laminate is stretchable in a direction parallel to the narrowing or necking of the web. The laminate possesses excellent water vapor permeability but acts as a barrier to the passage of odor-causing chemicals including ammonia.

摘要： The present invention relates to a composite material including a substrate with a first and a second layer, and a surfactant. The surfactant is applied to the first layer of the substrate. The surfactant acts to lower the surface tension of a fluid which contacts the first layer of the substrate such that the fluid is allowed or more readily enabled to pass through the first layer of the substrate, but such that the surfactant does not substantially adversely effect the absorption capacity or wicking height of the second layer of the substrate, as the second layer of the substrate substantially inactivates the surfactant upon contact or interaction therewith.

摘要： A biodegradable, cellulose-based collecting sheet that can be used in either a wet state or a dry state. The collecting sheet may be a double recreped cellulose substrate reinforced with a binder, such as a latex binder. Alternatively, or in addition to the binder, the collecting sheet may be coated with a dielectric material and electret treated to establish a charge on the dielectric material. Additionally, the collecting sheet may be embossed to provide more interstices and greater surface area to enhance the pick-up ability of the collecting sheet. The invention further includes a method of forming such a collecting sheet.

摘要： An apparatus and a method for ultrasonically producing a spray of liquid. The apparatus includes a die housing which defines a chamber adapted to receive a pressurized liquid and a means for applying ultrasonic energy to a portion of the pressurized liquid. The die housing further includes an inlet adapted to supply the chamber with the pressurized liquid, and an exit orifice defined by the walls of a die tip. The exit orifice is adapted to receive the pressurized liquid from the chamber and pass the liquid out of the die housing to produce a spray of liquid. When the means for applying ultrasonic energy is excited, it applies ultrasonic energy to the pressurized liquid without applying ultrasonic energy to the die tip. The method involves supplying a pressurized liquid to the foregoing apparatus, applying ultrasonic energy to the pressurized liquid but not the die tip while the exit orifice receives pressurized liquid from the chamber, and passing the pressurized liquid out of the exit orifice in the die tip to produce a spray of liquid.

摘要： An adsorbent filter for removing caffeine from liquids. The filter is composed of a liquid permeable, electret-treated matrix of fibrous material having individual exposed surfaces; and a relatively uniform distribution of adsorbent zeolite particulate material attached to individual exposed surfaces of the electret-treated fibrous material by substantially non-transient bonding, 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 matrix of fibrous material may be selected from woven fabrics, knit fabrics and nonwoven fabrics. 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.

摘要： An apparatus and method for controlling an ultrasonic transducer preferably including a signal generator circuit, a signal sensing circuit, a modulator circuit, and a bias circuit. The signal generator circuit provides a pulsed drive signal to the ultrasonic transducer. The signal sensing circuit senses the voltage and current of the drive signal. The modulator circuit provides a frequency control signal and an energy control signal to the signal generator circuit corresponding to a detected phase difference between the sensed voltage and the sensed current of the drive signal. The frequency control signal and energy control signal operate to adjust the frequency and energy level, respectively, of the drive signal.Within the transducer, a movable element in contact with a liquid is preferably positioned corresponding to the level of a dc bias signal provided by the bias circuit. By adjusting the level of the dc bias signal, the flow rate of the liquid is adjusted. By applying the drive signal to the transducer, the viscosity of the liquid is adjusted which establishes a second flow rate of the liquid. When the frequency and energy level of the drive signal are changed, a third flow rate of the liquid is established.

摘要： A polyolefin film for use as a sterilization wrap material which includes a film with a thickness of from about 0.005 mm to about 0.2 mm and having a plurality of discontinuous thinned regions. The thinned regions constitute at least about 25 percent of the surface area of the film. The thickness and area of the thinned regions are adapted to permit the passage of steam and water vapor through the film during steam sterilization. The film is made by a method which involves extruding a molten polyolefin film at a first temperature and passing the molten film through a nip. The nip includes an anvil roll and a pattern roll. The anvil roll has a smooth surface and the surface of the pattern roll is maintained at a temperature which is at least about 150.degree. C. lower than the first temperature and is selected to prevent sticking of the film to either roll.

摘要： A fibrous web having a length, a width and a thickness, with at least about 50 percent of the fibers aligned in a direction generally perpendicular to the length and width of the web. The web defines a plurality of spaced-apart gaps, each having a top and a bottom, and each of the gaps extends from one surface of the web at least about 50 percent through the thickness of the web. The density of a portion of the web defining the bottom of the gap is greater than the density of a portion of the web defining the top of the gap. The portion of the web which defines the top of the gap may be composed substantially of terminal ends of the fibers. In addition, the portion of the web which defines the bottom of the gap may be composed substantially of continuous fibers. The fibrous web may be a meltblown nonwoven web or a neck-stretched, meltblown nonwoven web. The fibrous web may be employed as a component of such absorbent products as diapers; incontinent care products; and feminine care products, such as sanitary napkins and tampons; filter elements; and the like. The web provides improved distribution of liquid in the direction of fiber alignment.
