Abstract: 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.

Abstract: The invention relates to a nonwoven surgical drape made of a non-cellulose containing base sheet having a source of additional weight uniformly distributed along side edges of the drape. The source of additional weight may have a mass per unit length between about three times and about eight times the basis weight of the base sheet.

Abstract: The present invention desirably provides a fabric including a synthetic fiber structure first zone, a synthetic fiber structure second zone, and a short fiber third zone. The first zone may include a spunbond web layer and a meltblown web layer. The synthetic fiber structure second zone may be positioned proximate to the synthetic fiber structure first zone and the short fiber third zone may be positioned substantially between the first and second zones. Desirably, the first and second zones are entwined.

Abstract: An apparatus and a method for the melt extrusion of a molten thermoplastic polymer, e.g., as fibers and nonwoven webs, which apparatus and method utilize ultrasonic energy to assist in the melt-extrusion process. The apparatus includes a die housing which defines a chamber adapted to receive the molten thermoplastic polymer and a means for applying ultrasonic energy to a portion of the molten thermoplastic polymer. The die housing includes a chamber adapted to receive the molten thermoplastic polymer, an inlet orifice adapted to supply the chamber with the molten thermoplastic polymer, and an extrusion orifice adapted to receive the molten thermoplastic polymer from the chamber and extrude the polymer. The means for applying ultrasonic energy is located within the chamber. The method involves supplying a molten thermoplastic polymer and extruding the molten thermoplastic polymer through an extrusion orifice in the foregoing apparatus to form a threadline.

Abstract: A method employing a ultrasonicator apparatus to emulsify a pressurized multi-component liquid. The apparatus includes a die housing comprising a chamber adapted to receive a pressurized multi-component liquid, an inlet adapted to supply the chamber with the pressurized multi-component liquid, an exit orifice defined by the walls of a die tip, and a means for applying ultrasonic energy to a portion of the pressurized liquid. The method for emulsifying a pressurized multi-component liquid comprising supplying a pressurized multi-component liquid to the 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 so that the multi-component liquid is emulsified, wherein the means for applying ultrasonic energy is excited, it applies ultrasonic energy to the pressurized liquid without applying ultrasonic energy to the die tip.

Abstract: A toilet tissue product may include a first cellulosic ply and a second cellulosic ply. Desirably, the first cellulosic ply further includes a single layer and the second cellulosic ply further includes a single layer. At least one ply may have a region that prevents fluid from striking through the tissue product.

Abstract: 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.

Abstract: The present invention is directed toward a surgical drape having a base sheet including a primary fenestration and at least one secondary fenestration, the drape being suitable for use in surgical procedures having multiple surgical sites.

Abstract: The present invention provides a disposable padded protective garment including a sheet material and at least one pad coupled to the sheet material. The disposable padded protective garment may further include a pocket coupled to the sheet material which, in turn, couples the pad to the sheet material.

Abstract: A dispensing system for individual folded webs having an area of non-uniform thickness across the length of the web is composed of several components. An outer housing defines an interior space in which stacking means for holding a stack of individual folded webs are mounted. A dispensing face is defined in the outer housing proximate to an end of the stacking means. The dispensing face has a central portion projecting out from the dispenser in the form of a first surface and a second surface joined at an obtuse angle and a dispensing throat located in the central portion at about the intersection of the first and second surfaces. The dispensing system also includes a stack of individual folded webs having an area of non-uniform thickness across the length of the web aligned so that an area of greatest thickness extends across the width of the dispensing throat.

Abstract: The present invention is a fenestrated craniotomy drape including a main sheet, translucent anesthesia side screens, a gusset forming the corners of the anterior edges of the drape, a run-off collection pouch whose back side is pressed flat and affixed to the drape, with a back side fenestration surrounding the fenestration of the main sheet, and a front side fenestration, and adjustable tube holders. The drape optionally includes a layer of a fenestrated absorbent material between the drape and the pouch, a solids screen and drain port in the pouch, and a ductile material about the edges of the front side fenestration of the pouch that holds the pouch open. The back-side fenestration of the pouch and those of the drape and the absorbent material are covered by an incise sheet, located between the back side of the pouch and the drape. The adhesive side of the incise sheet facing the patient is covered by a releasable backing.

Abstract: Methods are provided for preparing absorbent material, comprising providing non-broken down and uncut recycled fiber sludge having a moisture content of greater than about 40%; pelletizing said recycled fiber sludge to form wet pellets; and drying said wet pellets. The absorbent material is particularly useful as an industrial-grade waste liquid absorbent and/or an animal litter.
