  • Publication number: 20130216717
    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.

  • Publication number: 20130099418
    Abstract: A multi-piece mold for use in a method for making a slurry distributor includes a plurality of mold segments adapted to be removably secured together. The mold segments are configured such that, when the mold segments are assembled together, the assembled mold segments define a substantially continuous exterior surface adapted to be a negative image of an interior flow region of a slurry distributor molded thereupon. Each mold segment has a maximum cross-sectional area in a plane substantially transverse to a direction of movement of the mold segment along a removal path out of a respective opening of the molded slurry distributor. The maximum cross-sectional area of each mold segment is up to about 150% of the smallest area of the interior flow region of the molded slurry distributor through which the mold segment traverses when moving along the respective removal path.

  • Publication number: 20130098268
    Abstract: A flow splitter can include an inlet conduit and first and second outlet conduits separated by a junction portion. The inlet conduit can include an inlet end and a junction end. The inlet conduit is disposed along a main flow axis extending between the inlet end and the junction end. The inlet end defines an inlet opening. The junction end defines first and second junction openings. The first junction opening is disposed in spaced relationship to the second junction opening. The junction portion is disposed at the junction end of the inlet conduit between the first and second junction openings. The junction portion includes a substantially planar wall region that is substantially perpendicular to the main flow axis. The flow splitter can be placed in fluid communication with a cementitious slurry mixer and a slurry distributor with the flow splitter disposed therebetween.

  • Publication number: 20130099027
    Abstract: A slurry distributor can include a feed conduit and a distribution conduit in fluid communication therewith. The feed conduit can include a first and second feed inlets disposed in spaced relationship to each other. The distribution conduit can extend generally along a longitudinal axis and include an entry portion and a distribution outlet in fluid communication therewith. The entry portion is in fluid communication with the first and second feed inlets of the feed conduit. The distribution outlet extends a predetermined distance along a transverse axis. The first and second feed inlets each has an opening with a cross-sectional area. The entry portion of the distribution conduit has an opening with a cross-sectional area which is greater than the sum of the cross-sectional areas of the openings of the first and second feed inlets. The slurry distributor can be placed in fluid communication with a gypsum slurry mixer.

  • Publication number: 20130025504
    Abstract: The invention provides a set gypsum-containing product having increased resistance to permanent deformation and a method for preparing it comprising forming a mixture of a calcium sulfate material, water, and an appropriate amount of one or more enhancing materials chosen from condensed phosphoric acids, each of which comprises 2 or more phosphoric acid units; and salts or ions of condensed phosphates, each of which comprises 2 or more phosphate units. The mixture is then maintained under conditions sufficient for the calcium sulfate material to form a set gypsum material.
