  • Patent number: 10213208
    Abstract: A balloon is fashioned in the shape of a modified toroid that changes position by rotation. As a result, the toroidal balloon is an improvement over existing balloons for dilation and applying pressure since it can apply the pressure to both the external surface and the surface lining the balloon's internal channel and change position while applying that pressure. In addition, the toroidal balloon can apply a biologically active substance or medical device to a biological wall then leave that substance or device in place with the rotational extraction of the balloon. Other balloons for dilation or application of a substance or device need to be deflated to change their position.

  • Patent number: 10197209
    Abstract: In a method of reinforcing a pipe, a water penetration resistant layer and strengthening layer of fibrous material are impregnated with a curable polymer, positioned in a lining position near the pipe, and cured to form a water penetration resistant liner and a strengthening liner. The two layers can be impregnated and positioned separately or at once, for example, as a composite liner. Together, the liners provide a waterproof barrier and structural reinforcement to the resulting pipe. In a method of waterproofing a reinforced pipe, a water penetration resistant layer is impregnated with curable polymer, positioned over a previously installed reinforcing liner, and cured to form a waterproof barrier inhibiting ground water egress into the pipe. In certain embodiments of the methods, the water penetration resistant layer includes fibers woven in one of a satin weave and a twill weave.

    Abstract: An apparatus and method that accelerates curing of resin in a liner for a buried pipe includes an air inversion unit connected to an air compressor. The apparatus includes an inversion head with an interior inflatable plug. The plug, when inflated, creates a substantially airtight seal thereby maintaining pressure within the liner tube. The inversion head can then be removed from the liner inversion apparatus and a curing cap can be installed. To improve the wetting process, a vacuum head is installed at the inversion head and connected to a vacuum source. One end of the liner tube is attached to the inversion head and curable resin is poured into the opposite end. Vacuum pressure is applied to assist in the movement of the resin through the liner tube, ensuring uniform saturation. The resin is mechanically manipulated through the liner tube as the vacuum pressure is applied.

  • Patent number: 8585856
    Abstract: A fabrication process using an integrated form includes assembling at least two independent sections of composite laminate about a form, such that at least a portion of the sections overlap. A bonding agent is applied between the sections, at the overlap, and the form and laminate assembly are vacuum-bagged. The bag is sealed around a vent in the form, and about the laminate assembly. A vacuum is applied within the bag, to bond the sections, and the bagged assembly is autoclaved, to cure the bonded laminate sections. The vent allows equalization of autoclave pressures within and outside of the form, to prevent crushing or deformation of the form during cure. The form becomes an integral and permanent part of the final composite product.

  • Publication number: 20130174979
    Abstract: A pipe liner and a method of using the same are provided. The method includes inserting a pipe liner impregnated with a resinous material into a length of pipe, where the pipe liner has an outer diameter substantially equal to or greater than an inner diameter of the pipe. A bladder having an unstretched outer diameter less than the inner diameter of at least a portion of the length of pipe and capable of stretching circumferentially is inserted into the pipe liner. The bladder is expanded under fluid pressure against the pipe liner, pressing the pipe liner against an inner wall of the length of pipe. The resinous material is allowed to cure and harden, leaving a renewed pipe wall. The length of pipe may have a plurality of inner diameters, and the bladder stretches to produce a smooth interior surface of the pipe liner across the plurality of pipe diameters.

  • Patent number: 8418740
    Abstract: Composite sections for aircraft fuselages and other structures, and methods and systems for manufacturing such sections, are disclosed herein. A method for manufacturing a shell structure in accordance with one embodiment of the invention includes applying composite material to an interior mold surface of a tool to form a skin extending 360 degrees around an axis. The method can further include positioning a plurality of stiffeners on an inner surface of the skin. After the stiffeners have been positioned, a vacuum bag can be installed over the stiffeners and evacuated to press the stiffeners and the skin outwardly against the interior mold surface of the tool. Next, the skin/stiffener combination can be cocured to bond the stiffeners to the skin and harden the shell structure.

  • Patent number: 8377248
    Abstract: A system and method for forming a hollow, complex, monolithic composite part. Composite material may be placed around the mandrel, then an internal impermeable membrane may be placed into and/or through tunnels formed in the mandrel. Next, an external impermeable membrane may be placed around the composite material and sealed against itself and the internal impermeable membrane such that the mandrel and the composite material are both contained in an airtight manner between the internal and external impermeable membranes. Air may then be removed from within the sealed impermeable membranes, compressing the impermeable membranes against the mandrel and/or the composite material. The consolidated composite material may be hardened to form the composite part. Finally, the impermeable membrane may be removed from around the hollow composite part and from within the mandrel, followed by removal of the mandrel from within the composite part by breaking it up into smaller pieces.

  • Patent number: 8360108
    Abstract: An existing-pipe rehabilitation method for constructing a rehabilitation pipe inside an existing pipe to rehabilitate the existing pipe. A rehabilitation pipe is constructed inside an existing pipe by coupling segments in the circumferential direction and the lengthwise direction of the existing pipe so that the rehabilitation pipe has a constant outer diameter. A lining material impregnated with a liquid curable resin is inserted into the rehabilitation pipe thus constructed. The liquid curable resin is cured to line the internal circumferential surface of the rehabilitation pipe with the lining material so that an inner diameter of the rehabilitation pipe lined with the lining material is smaller than an inner diameter of the existing pipe.

  • Patent number: 8354139
    Abstract: A system for impregnating a liner with a curable substance enables the liner to be used to repair or refurbish an underground conduit. The system includes a vacuum pump having a vacuum line communicably connected thereto. The vacuum line has a vacuum inlet formed therein. The vacuum line supports the liner such that the liner covers and encloses the inlet. A supply of a curable substance has an applicator line connected thereto. The applicator line is proximate the vacuum line and has a discharge port located proximate the liner supported on the vacuum line. An applicator pump moves the curable substance through the applicator line and discharge port onto the liner while the vacuum pump draws a vacuum on the liner.

  • Patent number: 8328969
    Abstract: A method for curing a resin contained in a liner of an underground pipe or passageway by use of a mobile magnetron module. The module navigates the length of the passageway of pipe via air pressure which also keeps the liner inflated. A winch attached to the module regulates the rate at which the module traverses the passageway or pipe. As the module makes its way through the passageway or pipe, the magnetron emits microwaves which cures the resin. Additionally, a thermal imaging camera can be utilized in the module or trailing the module to monitor the status of the curing of the resin in its entirety.
