20090056221 | HYBRID COMPOSITE HYDROPONIC SUBSTRATE SYSTEM - A porous glass plant growth support structure, including a porous glass substrate and a plurality of interconnected pores distributed throughout the substrate. The substrate is typically formed from foamed glass and/or fused glass spheres and is characterized by a porosity of at least about 80 percent. The pore size is substantially between about 0.2 and about 5 millimeters and the substrate is sufficiently chemically stable such that water filling the plurality of interconnected pores experiences a pH shift of less than 0.5. | 03-05-2009 |
20090095041 | METHOD AND APPARATUS USING FOAMED GLASS FILTERS FOR LIQUID PURIFICATION, FILTRATION, AND FILTRATE REMOVAL AND ELIMINATION - A method of disposing of waste material in a waste stream, including positioning a porous foamed glass member characterized by an open-cell interconnected pore network in contact with a volume of liquid to be purified and removing an amount of an undesired material from the volume of liquid. | 04-16-2009 |
20090098379 | CLOSED-PORE GLASS SOIL ADDITIVES AND A METHOD FOR USING THE SAME - A granular soil composition consisting of a first mixture of organic material and a second plurality of substantially nonporous generally spherical foamed glass particles. The second substantially nonporous generally spherical foamed glass particles is typically present in amounts of between about 20 and 50 volume percent. The first mixture is typically selected from the group including bark, wood chips, rice husks, coco peat, peat moss and mixtures thereof and the plurality if substantially nonporous generally spherical foamed glass particles are characterized by mean strengths of at least about 350 PSI, diameters of between about 0.1 and 10 millimeters, and bulk densities of between about 15 and about 60 lb/ft | 04-16-2009 |
20090133440 | METHOD OF REDUCING THE OCCURANCE OF CRYSTALLINE SILICA IN FOAMED GLASS BY THE INTRODUCTION OF CHEMICAL ADDITIVES - A method of making a foamed glass body, including preparing an admixture of powdered glass, at least one carbonate based foaming agent, and at least devitrification inhibitor, heating the admixture to a first temperature to soften the glass, heating the admixture to a second, higher temperature to foam the softened glass into a foamed glass body, and cooling the foamed glass body. The crystal silica content of the so-formed foamed glass body is less than 1 weight percent. | 05-28-2009 |
20140294501 | FOAMED GLASS COMPOSITE MATERIAL AND A METHOD FOR USING THE SAME - A method of slowing an aircraft overrunning a runway, including paving an area immediately beyond the end of a runway with foamed glass bodies to define a bed, covering the bed with a layer of cementitious material to define a composite bed, and crushing at least a portion of the composite bed with an oncoming aircraft, wherein crushing the at least a portion of the composite bed removes kinetic energy from the oncoming aircraft to slow the oncoming aircraft. The composite bed is generally resistant to fire. | 10-02-2014 |
20150336836 | VERY LOW CRYSTALLINE SILICA FOAMED GLASS AND METHODS OF USING THE SAME - A method of treating a surface to remove unwanted material therefrom, including providing a foamed glass article formed from a starting mixture including glass, a carbonate foaming agent, and a devitrification agent selected from the group potassium phosphate, potassium phosphate tribasic, sodium phosphate and combinations thereof, and contacting the surface with the foamed glass article while providing relative movement between the surface and the article. The crystal silica content of the foamed glass body is less than 1 weight percent. The surface is treated by sanding, rubbing, scraping, degreasing, polishing, cleaning, smoothing, depilling, grooming, stripping, degumming, and combinations thereof. The surface is selected from the group comprising wood, metal, plastic, fiberglass, porcelain, glass, enameled surfaces, ceramic, concrete, or tile, and belongs to a member of the group comprising pools, spas, griddles, grills, fryers, bottles, glassware, cement pieces, marble, granite, monuments, skin, animal hides, textiles, garments. | 11-26-2015 |
20150336846 | FOAMED GLASS COMPOSITE MATERIAL AND A METHOD FOR USING THE SAME - An aircraft runway safety area for slowing an aircraft that has overrun a runway, including a brittle, nondeformable material for arresting the travel of an aircraft without catastrophically damaging the aircraft, the nondeformable material being configured to crush upon being contacted by the aircraft to effect arrest, and comprising incompressible material in the form of one or more foamed glass bodies, each respective body having a top surface, a bottom surface and oppositely disposed side surfaces, and a frangible matrix encasing the one or more foamed glass bodies, the frangible matrix fabricated to protect the incompressible material and having a breaking strength sufficient to readily break without subverting the arrestment characteristics of the incompressible material. The frangible matrix is different from the incompressible material. | 11-26-2015 |
20160097170 | FOAMED GLASS COMPOSITE ARRESTOR BEDS AND METHODS FOR MAKING AND USING THE SAME - A method of making a foamed glass composite engineered material arresting system for aircraft arrest, including heating glass frit to a temperature of between about 1500 degrees Fahrenheit and about 1900 degrees Fahrenheit, softening the frit to define a viscous glass material, and foaming the viscous glass material to yield a foamed glass body. The foamed glass body is then cooled, positioned in a bed located adjacent an airport runway, and at least partially surrounded with a structural matrix material to define a composite bed portion. The foamed glass body is incompressible and fails with a crushing failure mode. | 04-07-2016 |
