Abstract: A system may include a mobile application residing on an external device and an inhalation device. The inhalation device may include a mouthpiece, a mouthpiece cover, medicament, and an electronics module comprising a processor. The inhalation device may be configured to both prepare a dose of medicament for delivery to a user and cause the processor to transition between power states when the mouthpiece cover is moved from a closed position to an open position to expose the mouthpiece. The electronics module or the mobile application may be configured to generate usage events based on usage of the inhalation device by the user. The electronics module may also include a pressure sensor, and the electronics module or the mobile application may be configured to determine whether a usage event is a good inhalation event, a fair inhalation event, or a no inhalation event based on feedback from the pressure sensor.

Abstract: A nozzle tip [100] for a pulverized solid fuel pipe nozzle [200] of a pulverized solid fuel-fired furnace includes: a primary air shroud [120] having an inlet [102] and an outlet [104], wherein the inlet [102] receives a fuel flow [230]; and a flow splitter [180] disposed within the primary air shroud [120], wherein the flow splitter disperses particles in the fuel flow [230] to the outlet [104] to provide a fuel flow jet which reduces NOx in the pulverized solid fuel-fired furnace. In alternative embodiments, the flow splitter [180] may be wedge shaped and extend partially or entirely across the outlet [104]. In another alternative embodiment, flow splitter [180] may be moved forward toward the inlet [102] to create a recessed design.

Abstract: A furnace (10) includes a series of lower compartments (18) extending in a vertical arrangement, with at least one of the lower compartments (18) having one or more fuel nozzles (20) which tangentially fires fuel into the combustion chamber at an offset from a diagonal (DD) passing through opposed corners of the combustion chamber. At least one of the lower compartments (18) has one or more air nozzles (22) which tangentially introduces air into the combustion chamber along an offset direction which is offset from the diagonal (DD) to the same side as the fuel firing offset direction. The tangentially fired air and the offset fired fuel create a swirling fireball (RB) in the combustion chamber.

Abstract: An acoustical panel formed from a fibrous, open-celled material comprised of up to about 50% by weight fibers, between about 3% and about 10% by weight binder, between about 20% and about 75% by weight filler and about 0.01% to about 2.0% by weight surfactant. Additionally, voids are formed within the panel having an average distribution size diameter of about 50 &mgr;m to about 250 &mgr;m. The acoustic panel achieves very high sound absorption properties without the need for additional surface perforations, while maintaining a very high surface hardness.

Abstract: A doll or soft toy (2) includes a rotatable display device (12) with a plurality of faces (27), each carrying either a picture or photograph (10) in a transparent pocket (28) or fabric (32) complementary in appearance to the surrounding surface of the doll. The display device (12) can be rotated to display in turn different pictures or photographs or to conceal the display device.

Abstract: A method of operating a solid fuel-fired furnace having a plurality of windboxes each having a plurality of compartments through which fuel and air are introduced into the furnace and a fuel and air arrangement operated in accordance with the method are provided. Solid fuel is fed into the furnace and primary air and fuel are fed through the same compartments into the furnace in a direction tangential to a first imaginary circle generally located in the center of the furnace so as to interact with the fuel fed into the furnace so as to create a rotating fireball. Overfire air and offset air are also supplied into the furnace, the offset air being that portion of the air supplied to the furnace so as to support a second imaginary circle concentric to, and having a larger diameter than, the first imaginary circle.

Abstract: An air compartment of a corner windbox of a tangential firing system of a fossil fuel-fired furnace for injecting secondary air into the furnace. The air compartment includes a channel portion with an entrance end communicating with an air delivery duct and an exit end communicating via an exit assembly with the furnace opening. The exit assembly includes at least one vane for guiding an air stream and a mounting frame for supporting the vane relative to the channel portion for guiding thereby of an air stream passing from the channel portion through the furnace opening into the furnace. The vane includes a surface portion which intersects the horizontal plane at an acute angle and a pair of opposed transverse edges. The vane and the mounting frame are disposed within the channel portion such that the leading edge of the vane is upstream of the furnace opening.

Abstract: A minimum recirculation flame control (MRFC) solid fuel nozzle tip (12) that is suited to being cooperatively associated with a pulverized solid fuel nozzle (34) of a firing system in a pulverized solid fuel-fired furnace (10). The MRFC solid fuel nozzle tip (12) includes a secondary air shroud (46), secondary air shroud support (50) operative for supporting the primary air shroud (48) relative to the secondary air shroud (46), and a splitter plate (52) mounted in supported relation within the primary air shroud (48).

Abstract: An aqueous-based nylon fiber shrinking composition which can be formulated into a print paste is disclosed. The resulting print paste exhibits excellent viscosity stability and can be applied to nylon pile fabric to produce print-embossed pattern fabric.

Abstract: A pile fabric is treated overall with a solution containing a solvent for the fiber comprising the pile fabric. The solvent concentration of the solution is of a low enough level to produce little or no shrinkage by itself upon subsequent application of heat. Portions of the fabric before heating are treated with a solution to increase the solvent concentration on the pile fabric to a point where the solvent will have a shrinking effect on the fabric. The subsequently heated product then has an embossed effect.

Abstract: A resiliently flexible sealing element, conformable to the face of a wearer, in the form of a re-entrant flap is hingedly joined to and supported by a mask body in a spaced relationship thereto. The sealing element extends parametrically around the open side of the mask body and in selected locations thereabout is resiliently urged away from the mask body by web means disposed between the sealing element and the mask body. The web means provides pressure on the sealing surface of the sealing element directly at the deepest point on the user's face so as to eliminate the tendency of the sealing element or flap to pull away from the user's face at such selected locations.

Abstract: The method and product disclosed herein result in a needle-bonded fabric having a tufted fabric visual. This is accomplished by needling an unconsolidated web consisting of layers of two or more different colored fibers with a needle board having a reduced needle density and wherein the needles are arranged in the needle board in a predetermined pattern. The multi-layer web is processed through a fiber locker containing this reduced needle density board at a higher advance rate per stroke than normal production methods so that the space between the needle punches is greatly increased. The web is transported through the fiber locker in a continuous manner and produces the claimed product. One of the layers of the web is a blend of fibers of widely different fiber deniers and color.
