摘要： Improved tissue, continuous filament nonwoven laminates which are characterized by relatively high strength or toughness, relatively high loft and drape together with low noise or paper-like rattle. The improved tissue, continuous filament nonwoven laminates, while exhibiting a relatively high strength, are comprised of a low tensile strength, low basis weight, lightly bonded or unbonded layer of continuous filament nonwoven which is impregnated with about 50% to about 120%, based on the continuous filament nonwoven layer basis weight, of soft, tacky latex solids. The impregnated continuous filament nonwoven is combined under minimum combining pressures, while in the impregnated moist state between at least two, soft absorbent tissue facing layers prior to drying the laminate and curing the latex solids.

摘要： A two-stage upflow process for coal gasification and an apparatus useful therefor. An oxygen-containing gas and a first increment of a coal-in-water slurry are ignited in a horizontal fired slagging reactor by means of horizontal coaxial juxtaposed burner nozzles mounted in the reactor, thereby converting the oxygen, the coal, and the water into steam and gaseous combustion products. The discharge from the fired reactor is contacted overhead with a second increment of coal-water slurry in a vertical unfired heat-recovery unit connected to the upper end of the reactor. The heat evolved in the reactor is used in the heat recovery unit to convert the second increment of coal-water slurry into more steam, char and synthesis gas. The gas effluent is separated from the solid char, and synthesis gas is passed into a fire-tube boiler to recover heat and the cooled product gas is recovered as the desired fuel-rich product. The solid char is reslurried and recycled to the fired reactor 3 for further combustion.

摘要： A two-fluid nozzle for atomizing a liquid with a gas in which at least two conduits, a central and annular conduit, converge in an internal mixing zone for the liquid and gas, in which the nozzle has a central discharge orifice having a shoulder at its upstream end, and a two-piece, thermally resistant metal alloy heat shield for the central discharge orifice which the heat shield includes a retaining ring and an outwardly flaring liner for the outlet connected so that the retaining ring bears against the central outlet shoulder and is held in place by the flared construction at its downstream end, preferably the liner has heat conductive flexible packing disposed between its outside surface and the discharge orifice. The central discharge orifice may open into a protective cap which is cylindrical at one end and rounds out to an elliptical end surface.
