Abstract: A cementitious slurry mixing and dispensing system includes a mixer, a discharge conduit, and a pulser assembly. The discharge conduit is in fluid communication with the mixer. The pulser assembly is adapted to periodically compress a portion of the discharge conduit. The pulser assembly can include a compression member adapted to contactingly engage the portion of the discharge conduit and a drive mechanism adapted to selectively move the compression member into compressing engagement with the discharge conduit such that the part of the interior wall surface underlying the compressed portion is flexed.

Abstract: A multi-leg discharge boot can include an inlet conduit and first and second outlet conduits separated by a junction portion. The inlet conduit includes an entry segment, a transition segment and a heel portion disposed therebetween. The inlet conduit can include an inlet end and a junction end. A junction portion is disposed at the junction end of the inlet conduit between first and second junction openings. The junction portion includes a substantially planar wall region that is substantially perpendicular to a main flow discharge axis.

Abstract: Disclosed are methods relating to an extruded pregelatinized, partially hydrolyzed starch prepared by mixing at least water, non-pregelatinized starch, and acid to form a starch precursor. The acid can be a weak acid that substantially avoids chelating calcium ions or a strong acid in a small amount. In the method, pregelatinization and acid-modification of the starch precursor occurs in one step in an extruder. Also disclosed are methods of preparing board using the starch prepared according to the methods, as well as starches and boards prepared by various methods of the invention.

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.

Abstract: A method and apparatus for providing an evenly mixed additive enhanced gypsum slurry to a web. Calcined gypsum and water are inserted into a mixer (12) through at least one inlet (26,28) of the mixer (12). The contents are agitated to form a slurry. The slurry is passed from an outlet (34) of the mixer (12) into a conduit (38). An additive is introduced into the slurry along a length of the conduit (38) to achieve a flow stream of a slurry/additive mixture. A cross section (60) of the flow stream is expanded in the conduit (38) while not changing direction of the flow stream and a direction of the flow stream is changed while not expanding the cross section (60) of the flow stream and conduit (38), all prior to the flow steam exiting from an outlet (42) of the conduit.
