    Abstract: Embodiments of a system and a method for determining a surface smoothness of a facing specimen can be used in connection with the manufacture of products, including cementitious products such as gypsum wallboard, for example. Such systems and methods can be used to generate a composite smoothness factor based upon a measured mottle value and topography value using stochastic frequency distribution analysis.

    Abstract: A slurry distributor can include a distribution conduit and a slurry wiping mechanism. The distribution conduit extends generally along a longitudinal axis and includes an entry portion, a distribution outlet in fluid communication with the entry portion, and a bottom surface extending between the entry portion and the distribution outlet. The distribution outlet extends a predetermined distance along a transverse axis, which is substantially perpendicular to the longitudinal axis. The slurry wiping mechanism includes a movable wiper blade in contacting relationship with the bottom surface of the distribution conduit. The wiper blade is reciprocally movable between a first position and a second position over a clearing path, which is disposed adjacent the distribution outlet.

    Abstract: Disclosed is a composite gypsum board comprising a board core and a concentrated layer, as well as related methods of preparing board and slurries. The board core and the concentrated layer both are formed from water and stucco. The concentrated layer is designed to have higher density and/or nail pull than the core. The concentrated layer is further formed from a polysaccharide that forms a complex with calcium ions, e.g., an alginate compound such as sodium alginate. In some embodiments, the concentrated layer is formed from an enhancing additive to enhance strength therein, while the core is formed without using enhancing additive or less enhancing additive than used in forming the board core.

    Abstract: Disclosed is a method and system for blending a foam modifier with foaming agent on-line, e.g., as may be particularly useful for gypsum or cement slurries. The foam modifier comprises a fatty alcohol that is added to a gypsum or cement slurry that includes foaming agent, such as an alkyl sulfate surfactant. The fatty alcohol can be a C 6 -C 16 fatty alcohol in some embodiments. The use of such a foam modifier can be used, for example, to stabilize the foam, reduce waste of foaming agent, improve void size control in the final product, and improve the gypsum board manufacturing process.

    Abstract: A slurry distributor includes a feed conduit and a distribution conduit in fluid communication therewith. The feed conduit includes an entry segment with a feed inlet and a feed entry outlet in fluid communication therewith and extending along a first feed flow axis. The feed conduit includes a shaped duct having a bulb portion in fluid communication with the feed entry outlet. The feed conduit includes a transition segment in fluid communication with the bulb portion and extending along a second feed flow axis in non-parallel relationship with the first feed flow axis. The bulb portion has an area of expansion with a cross-sectional flow area that is greater than a cross-sectional flow area of an adjacent area upstream from the area of expansion. The shaped duct has a convex interior surface in confronting relationship with the feed entry outlet of the entry segment.
