Abstract:
The invention relates to an antimicrobial article in a sheet form including a porous sheeting substrate impregnated with a water-based antimicrobial composition comprising at least one polymeric emulsion or dispersion and at least one antimicrobial component that is substantially non-leaching and free of environmental hazardous material. The antimicrobial article may further comprise an adhesive coating disposed on at least one surface of the antimicrobial article. A removable protective film may be held to the exposed surface of the adhesive coating. The invention also provides a process of manufacturing the antimicrobial article. The antimicrobial article can be used, e.g., over fiberglass pipe insulation, on air duct liners, in building wall cavities, over gypsum wallboard and other construction surfaces.
Abstract:
The invention relates to a grid of synthetic material with two groups of parallel, load-bearing strands, wherein the strands of the first group extend in the longitudinal direction of the grid and the strands of the second group extend transversely to the longitudinal direction of the grid and the strands of both groups are joined together at their points of intersection. Alternating first and second portions are formed with strands extending in the direction of one of the two groups. The strand spacing of the first portions are larger than the strand spacing of the second portions. The second portions can be of an increased strength and can be used to fasten the grid without aids.
Abstract:
So as to reinforce a panel made of cellulosic fiberboard, bands of a reinforcing material, which is cementitious, are applied via spraying, as the panel is being conveyed, so as to cover a minor portion of the overall area of a given one of the expansive surfaces, and the panel is devoid of the reinforcing material except at the bands. The bands include two diagonal bands, each of which extends between diagonally opposite corners of the given one of the expansive surfaces, two longitudinal bands, each of which extends along a respective one of the longitudinal edges of the given one of the expansive surfaces, and two transverse bands, each of which extends along a respective one of the transverse edges of the given one of the expansive surfaces.
Abstract:
A laminated composite (multi-ply) radius filler includes a plurality of woven fabric reinforced plies cut to fill a radius gap (including, if appropriate, intentional overfill) to increase absolute strength, to increase specific strength, or to reduce cost by reducing cracking and distortion in the radius of a composite assembly. The present invention also describes the method of manufacture and method of use for such laminated composite radius filler.
Abstract:
A composite wood component is comprised of a wood filler core having opposed parallel flat side and end surfaces and opposed parallel top and bottom surfaces. Solid wood trim components are glued to the side and end surfaces of the filler core and oriented with its wood grain extending in a common direction. A solid high quality wood covering is adhesively secured to at least the top surface of the filler core and also has its wood grain oriented in the common direction with the trim components. The wood trim components have a thickness selected to be machined without exposing the wood filler core. The wood filler core is comprised of lower grade quality wood pieces glued together at opposed side edges to form a rectangular or a square core.
Abstract:
A method for forming a pultruded part includes collating reinforcing fibers by providing a first layer of reinforcing rovings extending in the longitudinal pultrusion direction, applying onto the first layer an intermediate layer of reinforcing fibers at least some of which include at least portions thereof which extend in the transverse direction and covering the intermediate layer with a second layer of rovings extending in the longitudinal direction. To the collated fibers is applied a resin so as to permeate through the layers and the materials are passed through a die to set the resin. The first and second layers are arranged to form first and second opposed surfaces of the part with the intermediate layer therebetween. The resin is a two part urethane resin which has sufficient strength to prevent the fibers from the first and second layers at the first and second surfaces respectively from breaking through the surface on bending of the wall thus allowing the use of the rovings at the surfaces with the transverse fibers therebetween so that the transverse fibers can be formed from loose or chopped fiber material from rovings rather than more expensive mat.
Abstract:
A composite wood product manufactured from waney lumber and a method for making the composite wood product. The method utilizes lumber that has been cut from a log such that the piece has a length substantially parallel to the longitudinal axis, a width substantially tangential to the growth rings and a thickness substantially perpendicular to the growth rings. The wane on the lumber is removed to create a complementary side surface for joining in alternating growth ring orientation to the adjoining piece across the joined profiled side surfaces.
Abstract:
A soft, meshed, electromagnetic shielding textile sheet is placed in a mold, and the mold is clamped. The soft, meshed electromagnetic shielding textile sheet is shaped so as to conform with the inner surface of the mold when the mold is clamped. Therefore, it is not necessary to fabricate beforehand any insert of a shape corresponding to that of the inner surface of the mold. Since the meshed, electromagnetic shielding textile sheet is impregnated with part of a resin injected into the mold to form an injection-molded resin body, the adhesion of the electromagnetic shielding textile sheet to the injection-molded resin body is improved.
Abstract:
A method of producing a mineral fiber-insulating web comprises the steps of firstly producing a first non-woven mineral fiber-web being a loosely compacted mineral fiber web of a low area weight, such as an area weight of 50-1500 g/m2, e.g. 100-1200 g/m2, such as 200-600 g/m2, or 600-1200 g/m2. The first mineral fiber web contains mineral fibers arranged generally in the longitudinal direction of the mineral fiber web. Secondly, the first mineral fiber web is moved in the longitudinal direction of the web and folded transversely relative to the longitudinal direction and parallel with a transversal direction of the first mineral fiber web, so as to produce a second mineral fiber-web containing mineral fibers arranged generally perpendicular to the longitudinal and transversal directions. Thereupon, the folded mineral fiber web is cured for bonding the mineral fibers together so as to produce the mineral fiber-insulating web comprising a central body containing mineral fibers arranged generally perpendicular to the longitudinal direction of the mineral fiber web. The method also optionally includes longitudinally compressing and/or transversally compressing the folded mineral fiber web. The folded mineral fiber web may additionally be combined with additional mineral fiber webs or coverings for producing a composite mineral fiber web product which is cured in a single curing process.

The functional high-strength adhesive sheet comprises a polyethylene layer, a nonwoven fabric in which the polyethylene is pressed to its one surface, and a functional polyethylene layer pressed to the other surface of the nonwoven fabric. The functional high-strength adhesive sheet is manufactured by the method comprising: the steps of preheating the nonwoven fabric in the system; supplying and pressing a polyethylene on one surface of the preheated nonwoven fabric; uniformly distributing the polyethylene pressed on the nonwoven fabric, thus forming a polyethylene layer; drawing and transferring a preliminary sheet provided with the nonwoven fabric and the polyethylene layer pressed thereon, and winding the preliminary sheet on a winding roller; preheating the preliminary sheet; supplying and pressing a functional polyethylene on the other surface of the preheated preliminary sheet; uniformly distributing the functional polyethylene pressed on the preliminary sheet, thus forming a functional polyethylene layer; and drawing and transferring an adhesive sheet provided with the preliminary sheet and the functional polyethylene layer pressed thereon, and winding the adhesive sheet on the winding roller.
