The discharge conduit (110, 1527, 1727) is in fluid communication with the mixer (1520, 1712). The pulser assembly (150, 850, 1050, 1250) is adapted to periodically compress a portion of the discharge conduit (110, 1527, 1727). The pulser assembly (150, 850, 1050, 1250) can include a compression member (705, 905, 1105, 1305) adapted to contactingly engage the portion of the discharge conduit (110, 1527, 1727) and a drive mechanism (720, 920, 1120, 1320) adapted to selectively move the compression member (705, 905, 1105, 1305) into compressing engagement with the discharge conduit (110, 1527, 1727) such that the part of the interior wall surface underlying the compressed portion is flexed.

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: Disclosed are hydrophobic finish compositions and cementitious articles made with the hydrophobic finish compositions. In some embodiments, the article is a waterproof gypsum panel surface reinforced with inorganic mineral fibers that face a flexible and hydrophobic cementitious finish possessing beneficial waterproofing properties. These waterproof gypsum panels have many uses, such as, tile backer board in wet or dry areas of buildings, exterior weather barrier panel for use as exterior sheathing, interior wall and ceiling, and roof cover board having water durability and low surface absorption. The flexible and hydrophobic cementitious finish can include fly ash, film-forming polymer, preferably silane compound (e.g., alkyl alkoxysilane), an extended flow time retention agent including either one or more carboxylic acids, salts of carboxylic acids, or mixtures thereof, and other optional additives. Preferably a pre-coated non-woven glass fiber mat is employed to provide the inorganic mineral fibers for the surface reinforcement.
