摘要： A method for stretching nonwoven sheet material in the cross-machine direction includes coursing a nonwoven sheet material through a deformable nip, the nip being formed between two rotating stretch surfaces having intermeshing peaks and troughs, the surfaces of the peaks and troughs being covered with a deformable material, and contemporaneously pressing the stretch surfaces together while rotating them, such that as the nonwoven material travels through the nip, the nip deforms from an initial flat formation into a convoluted formation.

摘要： An ultrasonic apparatus and a method for injecting a pressurized liquid fuel by applying ultrasonic energy to a portion of the pressurized liquid fuel. 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. 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.

摘要： A melt-extrudable polymeric strand with enhanced tensile strength formed by extruding a melt-extrudable polymer while subjecting the a portion of the polymer to ultrasonic energy. The melt-extrudable polymeric strand has a tenacity which is from about 1.5 to about 3 times the tenacity of an otherwise identical strand not made by applying ultrasonic energy to a portion of the melt-extrudable polymer while the melt-extrudable polymer is extruded. Desirably, the strand has a tenacity within a range from about 0.3 to about 0.9 g/denier. In a method for making such a strand, a molten melt-extrudable polymer is extruded through a die assembly, ultrasonic energy is applied to a portion of the melt-extrudable polymer within the chamber and without applying ultrasonic energy to the die tip, while an extrusion exit orifice receives melt-extrudable polymer from an extrusion chamber, and the extruded polymer is attenuated to form a strand. The extrusion of the melt-extrudable polymer and the excitation of the means for applying ultrasonic energy are controlled such that the strand has the above-described tenacity. A nonwoven web comprises the strands with enhanced tensile strength.

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： 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： 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. In another embodiment, the process includes the steps of: (1) forming a sheet having first and second fibrous surfaces wherein, upon the sheet being subjected to a sufficient temperature, the fibers forming the first fibrous surface are adapted to substantially completely melt prior to the fibers forming the second fibrous surface significantly melting; and (2) subjecting the sheet to a sufficient pressure and temperature 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. In some embodiments the liquid impermeable skin is subsequently apertured to make the sheet breathable. Products formed by these processes are also disclosed.

摘要： The present invention is directed toward a multilayer film which includes a first surface layer and a second surface layer. The first surface layer is composed of materials which disintegrate when subjected to conditions present in conventional sewage systems. The second surface layer is formed from a material which is essentially inert to water, urine and other bodily fluids. Typically, the second surface layer is an extremely thin coating which provides a waterproofing effect. The multilayer film may be utilized as an outer cover in a wide variety of products such as, for example, disposable diapers and feminine care products such as sanitary napkins. In one desirable embodiment the multilayer film includes only these two layers so that the material may be flushed down a conventional toilet without clogging the sewage system because the first surface layer rapidly disintegrates in water leaving only the thin, gossamer second surface layer which can pass through the sewage system without adversely affecting it.
