Abstract: A reinforcement membrane for reinforcing a roofing membrane has first and second layers including a fiberglass mat and a scrim of low-shrinkage organic fibers; a third layer comprising nonwoven low-shrinkage organic fibers providing an added mass of the low-shrinkage organic fibers for possessing latent shrinkage while the reinforcement membrane is in tension, which latent shrinkage is released in the absence of tension thereon during a temperature increase within a range of about 10° C. to about 30° C.; and a membrane coating material bonds together the three layers in tension, without completely filling interstices among the respective fibers of the three layers, wherein the interstices are adapted to be filled with a bituminous roofing composition.

Abstract: In one particular embodiment, the disclosure is directed to a conveyor belt including a set of warp knitted yarns configured in warp-oriented wales and a set of weft insert yarns inserted in the set of warp-oriented wales. The set of weft insert yarns have a cross-sectional aspect ratio at least about 2:1.

Abstract: A composite fabric for use in reinforcement, particularly tensile reinforcement, of cementitious boards and similar prefabricated building wall panels. The fabric is constructed as a mesh of continuously coated, high modulus of elasticity strands. The high modulus strands are preferably bundled glass fibers encapsulated by alkali and water resistant thermoplastic material. The composite fabric also has suitable physical characteristics for embedment within the cement matrix of the panels or boards closely adjacent the opposed faces thereof. The fabric provides long-lasting, high strength tensile reinforcement of the panels or boards regardless of their spatial orientation during handling. The reinforcement also enhances the impact resistance of the boards after installation. Included as part of the invention are methods for making the reinforcement, cementitious boards and panels including the reinforcement, and methods for manufacturing such boards and panels.

Abstract: An open grid fabric for reinforcing wall systems and a method of making same. First and second sets of substantially parallel, selected rovings are combined using certain knits, leno weaves, or adhesive methods. The rovings are direct-sized with at least a silane sizing and preferably have a linear density between 100 and 2000 grams per thousand meters and are arranged at an average of 3 to 10 ends per inch. A polymeric coating is applied to the fabric at a level of 10 to 150 parts dry weight of resin to 100 parts by weight of the fabric while assuring that the open grid remains open. A method for reinforcing a wall system and a wall segment product utilizing the novel open grid fabric of the present invention are also disclosed.

Abstract: A reinforced, impervious, unitary film and a method for making the same are disclosed. In a preferred embodiment, a film is produced from a layer of weft inserted warp knit scrim and at least one layer of lightweight, porous mat, together being impregnated with a suitable thermoformable plastic in liquid form such as PVC plastisol, then being set and calendered under pressure to deform the plastic and create a continuous, non-porous, unitary film. The resulting product is highly resistant to water absorption and hydrostatic pressure and essentially non-wicking.

Abstract: A liquid-vapor contact apparatus for use in distilling air on board a ship has vertical outer walls disposed in the manner of the vertical faces of a cuboid. The apparatus includes a plurality of spaced, parallel, vertical plates. Between each pair of adjacent plates there is a plurality of spaced, generally horizontal, liquid-vapor contact members each including a horizontal tray member and having edges and in fluid-tight engagement with the respective plates. There are a plurality of downcomers for conducting liquid from tray member to tray member, there being separate flow paths for liquid between each pair of adjacent plates. The two outermost plates form one pair of walls of the apparatus. The other pair walls comprises alternate edge portions of plates and spacer bars (or members).

Abstract: Facings for plastic foamed construction insulation board are made from paper treated with a treatment comprising about 10% to 100% of the weight of the paper including polymer, water repellant, and fire retardant. A reinforcing scrim may be combined with the paper. The treatment is applied to paper, the scrim is combined with the paper, and foam-forming liquids are applied to the paper to form a facing for a plastic foamed construction insulation board.

Abstract: A method and apparatus to apply pulp to a telecommunications conductor with an adhesive which is formed from acrylic resin solution. The solution is applied in a bath and is passed between wiping rolls with the feed speed of the conductor and the differential speed between the peripheral surfaces of the wiping rolls and the conductor being controlled together with the contact angle between the conductor and the rolls. This control results in a dried thickness of resin of no greater than 0.00015 inches and as little as 20 microns after further stages in the method. These steps include drying the solution in a solution drying oven, coating the adhesive with pulp and drying the pulp coated conductor.
