Abstract: A ball drop iris is provided for use in a ball drop testing apparatus. Included on the iris is a lower housing having an upper mounting flange having a ball opening and a body depending from the flange, the body defining a passage through which a test ball passes. A control ring is disposed on the upper mounting surface for sliding, rotating action relative to the lower housing. A plurality of iris petals is provided, each operationally connected to the control ring and to the upper mounting flange to pivot between a closed position in which the ball opening is blocked, and an open position in which the petals are simultaneously retracted and the opening is clear for passage of a test ball.

Abstract: A non-swelling joint tape for use with drywall applications includes a tapered trim strip body extending along a central body axis and a non-swelling backing paper. The tapered trim strip body includes a first surface, a second surface opposite the first surface, a first side, and a second side opposite the first side, and is at least partially constructed from a first dimensionally stable material. The non-swelling backing paper is at least partially secured to the second surface of the tapered trim strip body and is at least partially constructed from a second dimensionally stable material. The tapered trim strip body is dimensioned such that a first thickness between the first surface and the second surface at the central body axis is greater than a second thickness between the first surface and the second surface at the first side and the second side.

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 are cementitious articles with hydrophobic finish. In some embodiments, the article is a waterproof gypsum panel that is surface reinforced with inorganic mineral fibers that face a flexible and hydrophobic cementitious finish possessing beneficial waterproofing properties. The waterproof gypsum panels of the invention are useful in many applications, such as, for example, tilebacker board in wet or dry areas of buildings, exterior weather barrier panel for use as exterior sheathing, and roof cover board having superior water durability and extremely low surface absorption. The flexible and hydrophobic cementitious finish of the invention can include Class C fly ash, film-forming polymer, silane compound (e.g., alkyl alkoxysilane), and other optional additives.

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.

Abstract: An automatic dispensing device for wallboard joint taping is provided, including a body for holding a supply of viscous material and having a rear end and an opposite front end, a spool assembly disposed on the body and configured for supporting a spool of tape; at least one drive roller positioned at the front end and receiving an end of the spool of tape. Certain embodiments include an adhesive application assembly connected to the drive roller and mounted in operational relationship to the front end for dispensing a measured amount of adhesive upon an upper surface of the tape upon rotation of the at least one drive roll. In such embodiments, the body may be configured for holding sufficient adhesive to cover tape advanced by at least 200 rotations of the at least one drive roller.

Abstract: A joint tape for drywall includes a substrate layer having an elongate shape in a lengthwise direction and being flexible in the lengthwise direction and in a transverse direction. The tape further includes a covering layer disposed in bonding relation on the substrate layer. The covering layer is rigid in the transverse direction and configured to withstand compressive forces applied generally in the transverse direction and shear stresses applied generally along the transverse direction.
