  • Patent number: 10487906
    Abstract: Motion-damping systems and methods that include motion-damping systems are disclosed herein. The motion-damping systems are configured to damp relative motion between a base structure and an attached component that define a gap therebetween. The systems include an at least substantially rigid tubular structure that defines an internal volume and extends within the gap. The systems also include a magnetic assembly and a magnetically active body. One of the magnetic assembly and the magnetically active body is located within the tubular structure and the other of the magnetic assembly and the magnetically active body is operatively attached to a selected one of the base structure and the attached component. The magnetic assembly is in magnetic communication with the magnetically active body such that a magnetic interaction therebetween resists motion of the attached component relative to the base structure. The methods include dissipating energy with the motion-damping system.

  • Publication number: 20190330111
    Abstract: The invention relates to a low-permeability geotechnical barrier material including a blend of approximately equal parts of: aggregate particles, sand-size particles and manufactured composite particles that include a hydratable sealant material composed of naturally-occurring clay minerals and/or polymer-enhanced clay minerals, such that the actual percentage of clay mineral component is less than 10% by weight in the blended material. In a particular embodiment, the construction of a low-permeability geotechnical barrier using predominantly coarse grain materials by conventional compaction efforts is rarely attempted due to the difficulty of maintaining a uniform mix of well-graded sand and aggregate blends necessary to achieve low permeability. The regularly achievable permeability offered by this material blend when installed with specific proscribed techniques using conventional equipment can be 5×10?8 cm/sec or lower.

  • Publication number: 20190194069
    Abstract: Composite particles of a hard core coated by a layer of hydratable, swellable clay such as bentonite are useful for constructing, modifying and/or supporting lifeline structure such as dams, berms and levees, and/or pipelines or conduits for oil, gas, sewage, water, or cables or wires for transmission of electrical power or data information. The method involves placing the composite particles in a location within, below, or about the lifeline structure, and hydrating them to cause them to swell and fill and seal the voids around the structure to form a resilient support having a high damping ratio and low hydraulic conductivity that is maintained after exposure to strain forces. The composite particles are advantageous in damping seismic waves and reducing the potential damage from an earthquake, explosion, tremor, fatigue loading, or similar seismic event.

  • Publication number: 20170247772
    Abstract: Composite particles are used in combination with ore particles in an ore-refining or purification process, such as in a steel- or iron-making process. The composite particles comprise a core, which may be an aggregate of limestone, dolomite, or another ore particle. The core is surrounded by a coating layer of a metal dust and a binder. The metal dust may be iron oxide dust, which, along with limestone, is prevalent in the iron smelting process anyway. In this way, the composite particles help to recycle otherwise wasted and hazardous iron dust. The binder may be mineral clay such as bentonite, montmorillonite or kaolinite, and may comprise about 2-10% by weight of the particle.

  • Publication number: 20170203346
    Abstract: Contaminated sediment is re-mediated using a self-regenerating reactive sedimentation capping system comprising a system of composite particles having a core and a coating. The coating of at least some particles further include a complexing or sorptive reactive material, such as activated carbon, appatite, a clay or organoclay, or a synthetic sorptive such as Sorbster™. The same or different particles contain a composition of dormant microbes capable of utilizing various contaminants as a food source. The same or other particles may also contain nutrients, micronutrients, vitamins, cofactors, buffers or other adjunctive compounds to sustain the microbes. The microbes feed on and degrade the contaminant compounds complexed, absorbed or adsorbed by the reactive material, thereby regenerating the reactive material for re-use.

  • Publication number: 20170189948
    Abstract: Contaminated sediment is remediated using a sedimentation capping system comprising composite particles having a core and a coating containing a statin composition. The statins are useful for inhibiting the growth of methanogens, known anaerobes that produce methane from organic materials found in sediments. The reduction in methane production avoids several problems in capping systems, including reduced ebullition that may breach the barrier cap, reduced mobilization and bioavailability of methylated toxins to aquatic life above the cap.

    Abstract: Reactive treatment cells (RTCs) are described in combination with sediment capping systems as a means for environmental remediation. RTCs include an impermeable housing defining an interior, a permeable ceiling and floor typically including filtration materials such as geotextiles, and at least one interior compartment for treatment reagents. One RTC includes a gabion-like cage structure retaining a geomembrane-supported geosynthetic clay liner (GM-GCL) housing, while a second embodiment includes a hard, cylindrical shell as a replaceable reagent cartridge. RTCs may be employed in initial capping system installations or retrofitted into existing capping systems. RTCs may include optional baffles, flow restrictors, floating discs, sensor probes, and two or more serial reagent zones or compartments.

  • Publication number: 20130196061
    Abstract: Fiber-containing composite particles and fiber-reinforced barrier matrix compositions made from them are disclosed. The composite particles include a core, a hydratable clay mineral layer, an optional protective coating, and a reinforcing fiber. The fiber may be present in any or all of several locations: adhered to the core, dispersed in the hydratable layer or in the protective coating. Upon hydration, the hydratable clay mineral layer swells and forms a matrix that cohesively holds the fibers and the core in a fiber-reinforced barrier matrix composition.

  • Patent number: 5897946
    Abstract: A flowable material to isolate or treat a surface consists of a plurality of manufactured composite particles. Each composite particle includes a core, and a sealant layer at least partially encapsulating the core. The core is relatively dense compared to the sealant layer, and the composite particle has a specific gravity greater than one. The sealant layer includes a clay mineral, a pozzolanic material and/or activated carbon. A sealant layer formed of a pozzolanic material creates a hardened underwater barrier layer. The sealant layer can also include natural fibers such as cellulose or man-made fibers such as glass, carbon or plastics to mechanically improve the geotechnical properties of the layer when hydrated. The composite particles can also include a material to treat the contaminants or otherwise improve the surrounding environment.

  • Patent number: 5763734
    Abstract: A method for containing or removing contamination from a substrate includes applying a material such as a polyurea elastomer to the contaminated substrate. Preferably, the material sets in less than about 1 hour and is substantially unaffected by exposure to radiation. The contaminants can be contained or shielded on the substrate by the material to reduce exposure to the contaminants. In one preferred embodiment, this invention relates to the encapsulation of objects or surfaces to shield persons in the area from contamination. Alternatively, the material can be removed from the substrate to remove contaminants. Preferably, the material provides a Decontamination Factor of at least about 10. In another preferred embodiment, the material is applied hot to the contaminated substrate to increase its effectiveness in removing contaminants. The present method can also prevent contamination of an uncontaminated substrate.
