  • Patent number: 11518122
    Abstract: Tires having a magnetic tire sealing material containing magnetic particles are described for detecting the presence of one or more sealed punctures in the tire. The tires can have a sealed tire portion that is formed by the magnetic tire sealing material flowing into and filling a puncture in the tire. The sealed tire portion includes a portion having magnetic particles and the portion being at the outer surface of the tire such as in the tread area. The tire can be positioned within the detection zone of an apparatus capable of detecting magnetic particles to indicate whether the tire contains a sealed puncture filled with the magnetic tire sealing material.

  • Patent number: 10016954
    Abstract: Geocomposite articles that can provide a barrier against high conductivity water e.g., ocean water, are described and their method of manufacture, for waterproofing surfaces that contact high conductivity water. The geocomposite article mat includes a woven or non-woven geotextile sheet or mat containing a powdered or granular partially cross-linked acrylamide/acrylate/acrylic acid copolymer across its entire major surface(s). The powdered or granular copolymer has an unexpectedly high free-swell when hydrated with High Conductivity water, such as ocean water. A liquid-impermeable cover sheet is adhered to the upper major surfaces of the filled copolymer-carrying geotextile to provide a primary high conductivity water barrier layer that, if ruptured, is sealed by the swell of an underlying layer of water-insoluble, partially cross-linked acrylamide/acrylic acid copolymer.

  • Publication number: 20130056215
    Abstract: Disintegrative particles having a disintegrative coating surrounding a disintegrative core may be pumped within an aqueous treatment fluid downhole to a subterranean formation. With time and/or change in wellbore or environmental condition, these particles will either disintegrate partially or completely, in non-limiting examples, by contact with downhole wellbore fluid, formation water, or a stimulation fluid (e.g. acid or brine). Once disintegrated, metals or compounds are released which raises the fluid pH and forms a structure that selectively inhibits or shuts-off the production of water from water-producing zones. The disintegrative particles may be made by compacting and/or sintering metal powder particles, for instance magnesium or other reactive metal or their alloys. Alternatively, particles coated with nanometer-sized or micrometer sized coatings may be designed where the coatings disintegrate faster or slower than the core in a changed downhole environment.

  • Publication number: 20120247366
    Abstract: An environmentally acceptable leak sealant comprising lava rock aggregate (scoria) for sealing leaks in dams, holding ponds or other water-containing structures. The aggregate is selected and graded for particle size and density. Particles of different sizes co-operate to engage walls of the leak and interlock with each other to form a seal within a leak opening. The particles must sink at a suitable rate, and become entrained in water flow through the leak. Beneficially larger particles have a generally higher sink rate than smaller particles, and so arrive first at the leak to staunch a major part of the flow; intermediate and smaller particles follow to form an effective seal. Applications include sealing sluice gates, stop logs at hydroelectric dams to reduce water wastage for increased electricity productivity, for maintenance requiring de-watering of the turbine; or for sealing leaks in cracks in bedrock or concrete structures associated with dams.

Either of these items may be placed into the radiator of a vehicle. The bag and the tablet each dissolve, and the contents spontaneously disperse into the radiator coolant to seal pin hole leaks.

  • Patent number: 6432182
    Abstract: In accordance with the present invention, a method of treating the surface of an organic substrate, particularly a circuitized surface of an organic substrate, which method reduces the spread of adhesive resin that is subsequently deposited on the surface, is provided. This method comprises the steps of applying a treatment solution comprising a fatty acid compound, an alkalizing agent, and a solvent comprising water and from about 5% to about 90% by volume of an organic solvent selected from the group consisting of an alcohol, a glycol ether, and combinations thereof to the surface; and then removing substantially all of the solvent from the solution to provide a thin film on the surface of said substrate. The film comprises the fatty acids that were present in the treatment solution. In a preferred embodiment the treatment solution further comprises a chelating agent.

  • Patent number: 6264732
    Abstract: A puncture preventive sealant capable of reducing the content of cellulose fibers for suppressing the cost of the sealant while keeping a high sealing performance due to the cellulose fibers. A sealant, which is filled in a sealant chamber defined in a tube adjacently to an air chamber, contains synthetic fibers and cellulose fibers in a solvent. The content of the synthetic fibers is in a range of from 75 to 90 wt % and the content of the cellulose fiber is in a range of from 25 to 10 wt %. Since the sealant is filled in the sealant chamber having a capacity significantly smaller than that of the air chamber, the separation of the synthetic fibers due to a centrifugal force substantially exert no adverse effect on the characteristics of the sealant. Accordingly, the content of the cellulose fibers can be set at such a minimum value so as to block a large puncture hole. As a result, it is possible to reduce the cost by reducing the content of the cellulose fibers.

  • Patent number: 5772747
    Abstract: A sealant composition especially useful for stopping punctures in vehicle tires includes: (a) a viscous fluid such as propylene glycol or polypropylene glycol; (b) one or more fibrous materials such as cellulose, wool, nylon, rayon, hair, wollastonite, rock-wool, glass wool fibers, polyester, polypropylene, or other material of like nature; and (c) flat plate-like particles, such as mica. In one embodiment, the composition is too viscous to be readily passed through a pneumatic tire valve stem, so the viscous product is installed into the tire while the tire is dismounted from the wheel. In another embodiment, the composition is made of two parts, each of which is sufficiently low in viscosity to pass readily through the valve stem, but which react on mixing inside the tire form a liquid of higher viscosity.

  • Patent number: 5755863
    Abstract: A sealing system and sealing composition are provided for inflatable articles containing air under pressure. The sealing composition includes particles or particulates of three-dimensional shapes having sharp corners thereon which tend to dig into the article around the opening and wedge themselves therein. The sealing composition also includes fibers, at least some of which are fibrillated. The fibers tend to wrap around the particles and further plug the leak opening. The particles and the fibers are in a liquid carrier which also tends to form a bond of the particles and fibers in the leak opening. The particles in the composition have dimensions covering a particular range of sizes for different articles, the larger dimension being useful in larger dimension articles, such as large tires for construction machines, and the smaller dimension being useful in smaller articles such as footballs and basketballs, for example.
