20110104372 | Polymer injection method for blocking piping in dikes and dams - A polymer injection method and apparatus for blocking piping in dikes and dams, uses non-water reacted two-component polymeric material to produce a hydra-insensitive expanding polymer for blocking piping channel. A transferring device is provided to the method, which includes an injection gun, an injector, and a hollow tube, wherein the injection gun connects with an entrance end of the hollow tube through the injector, and an outlet end of the hollow tube inserts into the entrance of the piping channel. The two components of the polymeric material are respectively transported to the injection gun, and are mixed and injected from the gun with high pressure, through the injector, to the hollow tube, and then pushed into the piping channel. Under the chemical reaction, the mixed material expands inside the receiver and becomes foamed solid from liquid, and then the polymer receiver inflates and blocks the piping channel quickly. | 05-05-2011 |
20110274835 | METHOD FOR MEMBRANE DEPOSITION - A method and apparatus for applying a uniform membrane coating to a substrate, such as a honeycomb structure, having a plurality of through-channels, wherein the through-channels have an average diameter of less than or equal to 3 mm. The method includes providing a liquid precursor comprising membrane-forming materials to the substrate and applying a pressure differential across the substrate. The pressure differential causes the liquid precursor to travel uniformly through the through-channels, depositing the membrane-forming materials on the walls of the through-channels and forming the membrane on the walls of the through-channels. The apparatus includes a chamber capable of holding the substrate and of maintaining a pressure differential across the plurality of through-channels. | 11-10-2011 |
20120058268 | METHOD OF MAKING CONVOLUTED COATED BRAIDED HOSE ASSEMBLY - A seamless convoluted hose assembly. The assembly includes: a tubular inner liner having an outer surface, an inner surface, and an inner liner wall therebetween which defines a passageway. The assembly further includes a helical coil or a plurality of annular loops which produce convolutions in the outer surface of the tubular liner when the tubular inner liner is forced through the helical coil or plurality of loops under heat and pressure. | 03-08-2012 |
20130071563 | Methods and Systems for Coating and Sealing Inside of Piping Systems - Methods and systems for cleaning, coating and sealing leaks in existing pipes, in a single operation. A piping system can be cleaned in one pass by dry particulates forced and pulled by air throughout the piping system by a generator and a vacuum. Pipes can be protected from water corrosion, erosion and electrolysis, extending the life of pipes such as copper, steel, lead, brass, cast iron piping and composite materials. Coatings can be applied to pipes having diameters up to approximately 6″. Leak sealants of at least approximately 4 mils thick can cover insides of pipes, and can include novel mixtures of fillers and epoxy materials, and viscosity levels. A positive pressure can be maintained within the pipes during applications. Piping systems can be returned to service within approximately 96 hours. | 03-21-2013 |
20140037844 | Method for Cleaning the Interior Surface of Hollow Articles - A method of blast cleaning the inside of a hollow article, such as a storage tank. The method includes the introduction of outside air and evacuation of inside air to permit blast cleaning to be carried out while managing the conditions within the enclosed interior space within the hollow article. Managing the interior space conditions permits rapid application of protective coatings to the cleaned surface. | 02-06-2014 |

The conduit treatment system generally includes a tube having an absorbent first layer and a non-absorbent second layer. When not inverted, the first layer is the interior of the tube and the second layer is the exterior of the tube. The first layer will be adapted to absorb a treatment which is to be applied within a conduit. By securing a tether between an inversion unit and a closed-off end of the tube, the tube may be wound onto the inversion unit's shaft. The first end of the tube may then be anchored to the inversion unit's connector head to allow for inversion of the tube within a conduit. Upon inversion, the first layer will apply its absorbed treatment to the inner walls of the conduit. | 04-07-2016 |
