    摘要： An improved process calcining a gypsum/cellulosic fiber slurry to produce a composite gypsum/cellulosic fiber product resides in adding a selected crystal modifier to the gypsum/cellulosic fiber slurry prior to the heating step to reduce the time necessary to carry out the calcination process, to reduce the temperature at which the calcination process is run or to increase the aspect ratio of the acicular calcium sulfate alpha hemihydrate crystals formed during the calcination process. Useful crystal modifiers include aluminum sulfate, aluminum chloride, chlorine, zinc sulfate, iron (III) sulfate, aluminum sulfate hexadecahydrate, iron (II) sulfate heptahydrate, iron (III) sulfate pentahydrate, zinc sulfate heptahydrate, copper sulfate pentahydrate, copper chloride dehydrate, manganese sulfate monohydrate and trisodium phosphate.

    摘要： A compressor assembly for a gas turbine engine includes rotatable impeller with forward and aft ends, including: an annular hub defining a generally concave-curved cross-sectional inner flowpath surface at its radially outer periphery, the inner flowpath surface extending between an inlet and an exit; an annular array of airfoil-shaped inducer blades extending radially outward from the inner flowpath surface near the forward end; and an annular array of exducer blades extending outward from the inner flowpath surface, the array of exducer blades axially spaced apart from the array of inducer blades; a non-rotating shroud assembly surrounding the impeller and including a convex-curved outer flowpath surface, wherein the inner and outer flowpath surfaces cooperate to define a primary flowpath past the blades and the stator vanes; and an annular array of airfoil-shaped stator vanes extending radially inward from the outer flowpath surface into a space between the inducer and exducer blades.

    摘要： An improved method and apparatus for imparting a smooth surface to gypsum fiber panels. The method involves imparting energy to the surface of a slurry as the slurry is dewatered just prior to rehydration. The apparatus used to impart the energy is a water spray including a source of pressurized water such as a pump, a distribution manifold and a plurality of nozzles to direct the water spray at the surface of the slurry. In operation, the water spray is directed against the surface of the slurry. The flow disrupts the slurry to a fraction of its total depth, thus dispersing clumps or flocs of commingled crystals and fibers in the depth that would give the surface of the finished panel a rough surface if they were allowed to remain.

    摘要： An improved method for texturing gypsum fiber panels and producing surface textured panels, edge tapers, and deeper patterned wainscot-type panels, involving the use of a flexible die with a textured surface. The die is pressed onto the panel in its slurry state just after the onset of an exothermic rehydration reaction. Partial hydration and setting occur during pressing by the die to form a textured mat. The mat is removed from contact with the die at a point along the rehydration temperature curve about at or less than one-half of the rise to the greatest rehydration temperature.
