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: A lightweight, high-strength composite fabric suitable for use in carpet backing, roofing and membranes and other products which employ rugged fabrics. The composite fabric comprises a layer of nonwoven material disposed between a layer of low shrinkage warp strands and a layer of low shrinkage weft strands. The layers are stitched or knitted together and the resultant fabric may be coated with a resin or sizing to prevent slippage between the several layers of the fabric and impart a measure of stiffness to the fabric. The fabric may be manufactured in sheet or, more preferably, roll form and may be coated with materials suitable for desired end applications, e.g., bituminous material whereby the fabric may function as a ready-to-use roofing membrane or other high-strength fabric product.

Abstract: This invention provides reinforced, water-resistant structures, and methods of manufacturing and installing such structures. These structures include bituminous mastic material having first and second major surfaces and semi-rigid, open mesh material disposed within the mastic material. The structure may be prefabricated or assembled in situ and can be bonded to an underlying substrate by the application of heat or pressure to form an adherent bond. The reinforced structure has a tensile strength of at least about 300 psi or more.

Abstract: A structural corner reinforcement for strengthening frames includes at least a first segment and a second segment of frame bar, each formed into a desired profile and each having a hollow interior portion, a reinforcing channel having a first leg and a second leg arranged at an angle to the first leg, with ends of the channel securing first and second extensions to extend the first and second legs, respectively, at least one of (i) a portion of the first extension of the reinforcing channel being inserted through a first end of the first segment of the frame bar into and substantially spaced from surfaces of the hollow interior portion of the first segment and (ii) a portion of the second extension of the reinforcing channel being inserted through a first end of the second segment of the frame bar into and substantially spaced from surfaces of the hollow interior portion of the second segment, and a rigid reinforcing and structural material, formed from a foamed chemical, inside at least one of (i) the hollow

Abstract: Conduit liners and methods for their construction and use are provided. The liners include a first flexible layer mechanically bonded to at least one glass-containing layer and folded to form a tubular laminate. The laminate can be penetrable by resinous liquid capable of setting the form of substantially continuous matrix within the laminate following the expansion of the laminate within a conduit. In preferred versions of the liner, multiple glass layers are provided on the inner and outer diameter of the construction with a polyester core so as to meet minimum thickness requirements for vibration resistance under American in situ pipe vibration resistance codes.

Abstract: Hand-tearable barrier laminates are provided which include a reinforcing layer having a first tensile strength laminated to flexible cellulosic web comprising open porosity and a second tensile strength which is less than the first tensile strength. The web is treated with a water-resistant polymeric resin for providing liquid water resistance to the web while permitting water vapor to pass through it. Inexpensive web materials can be substituted for polymer foam and microperforated plastic films currently employed by the housing industry.

Abstract: A corner assembly, for holding a screen frame, is provided in which the corner assembly has a pair of arms disposed to be connected to frame side members, preferably by being telescopically received therein, for installation inside a fixed frame at the periphery of a window. Each corner assembly includes a slide member carried in a slideway, which slide member carries a retaining protrusion extending therefrom, and with the slide member having a manually engageable, movable button, movable longitudinally, to move the slide member and its protruding button between two positions, one position of which is an extended position for the retaining protrusion, and another position of which is a retracted position therefor. In the extended position of the retaining protrusion, the protrusion is adapted to engage within a recess of a fixed frame member of a window.

Abstract: Corner members and frame members forming an assembly is provided, for holding a screen or the like, in which the corner members have arms disposed to be connected to frame members, preferably by being telescopically received therein, for facilitating retaining the frame assembly, which is a removable assembly, inside a fixed frame of a window. Upper corner members of a moveable frame have a U-shaped attachment means formed by an upwardly projecting flange and tab forming U-shaped channels. The top of the frame having the U-shaped attachment means is inserted at an angle into a downwardly projecting lip means on a fixed frame such that the U-shaped attachment means loosely embraces the lip means. The moveable frame is rotated until the U-shaped attachment means fully embraces the lip means, the moveable frame is flush with fixed frame, and the moveable frame is locked into position against the fixed frame with retaining mechanisms on the remaining two corners of the moveable frame.
