Abstract: A fire apparatus includes an engine, a fluid delivery system, and a controller. The fluid delivery system includes a first pump that provides a first fluid output at a first pressure, and a second pump positioned downstream of and coupled to the first pump in a serial arrangement. The second pump is driven by the engine. The second pump provides a second fluid output at a second pressure. During a first mode, the first fluid output is dischargeable from a low pressure discharge. During a second mode, the second fluid output is dischargeable from a first high pressure discharge and/or a second high pressure discharge, the engine operates at a first set point when the second fluid output is discharged from the first high pressure discharge, and the engine operates at a second set point when the second fluid output is discharged from the second high pressure discharge.

Abstract: A fire fighting vehicle includes a chassis, an engine coupled to the chassis, a fluid tank configured to store a fluid, a fluid delivery system, and a controller. The fluid delivery system includes a first pump, a second pump, a low pressure discharge, a first high pressure discharge, and a second high pressure discharge. The first pump is coupled to the fluid tank and configured to pump the fluid therefrom at a first pressure. The second pump is positioned downstream of and coupled to the first pump in a serial arrangement. The controller is configured to selectively vary at least one of a speed, a power output, and a torque output of the engine and thereby provide the fluid to at least one of the first high pressure discharge and the second high pressure discharge at a target discharge pressure.

Abstract: An apparatus for forming a shaped fibrous nonwoven structure including a delivery system adapted to provide a high speed composite stream comprising thermoplastic polymer fibers and a secondary material. The apparatus also includes a movable collection device having a collection surface which intersects the composite stream, and at least one deflector to mechanically redirect at least a portion of the composite stream. Further the deflector moves in synchronization with the movable collection device, such that the composite stream is collected on the collection surface forming a fibrous nonwoven structure having at least one non-linear edge.

Abstract: A method of making stretchable absorbent articles includes the steps of providing a continuous substrate layer, providing one or more streams of adhesive fibers and superabsorbent particles, shaping the one or more streams of adhesive fibers and superabsorbent particles, depositing the adhesive fibers and superabsorbent particles on the substrate layer to form a plurality of shaped absorbent cores bound to the substrate layer, and separating the absorbent cores from each other. The absorbent cores thus formed do not prevent stretching of the substrate layer. The combination of absorbent core and substrate layer can be used in a wide variety of personal care absorbent articles and medical absorbent articles.
