摘要： A combustible carbonaceous briquette and method of making the briquette wherein a finely divided carbonaceous material is formed into a desired briquette shape under high pressure whereby carbonaceous particles are bound together by a pre-cooked mixture of an organic binder and a water-swellable clay. The combustible carbonaceous material is present in the briquette composition in an amount of about 85% to about 96% by weight; the organic binder is present in an amount of about 2% to about 8% by weight; and the water-swellable clay is present in an amount of about 1% to about 5% by weight. The weight ratio of organic binder to water-swellable clay, dry weight basis, is in the range of from about 1.5 to about 3.0 to 1.

F. to about 2300.degree. F. during a period of time preferably of more than about 30 minutes, and preferably for a period of about 1 to 2 hours, particularly to about 2000.degree. F. to about 2200.degree. F., and a method of casting molten metal against the heat treated carbon particles wherein the non-porous carbon foundry sand is combined with a suitable binder with which mixture a mold is formed to cast metal parts. The non-porous carbon sand also is useful in forming molds, cores, shell molds and shell cores and otherwise in using the carbon sand to replace other molding an core-making sands used in the foundry industry.

摘要： An article of manufacture including an elongate confined mass of a water-swellable clay for sealing joints or seams between adjacent water-barrier materials or for plugging defects or other unsealed areas adjacent to a water-barrier layer. The elongate, confined mass of water-swellable clay is manufactured in any desired cross-sectional shape or configuration e.g. circular, eliptical, rectangular, square, and the like and can be manufactured in roll form for dispensing individual confined masses of water-swellable clay individually. The water-swellable clay is confined within a layer of material that permits the entrance of water to contact the water-swellable clay for hydration of the clay, such as by being water-porous or water-soluble and such that upon sufficient hydration of the confined mass of water-swellable clay, the confining layer will dissolve sufficiently, burst or tear to permit relatively free movement of the hydrating and expanding water-swellable clay.

摘要： A flexible or rigid panel, and method of making the panel, useful as a water barrier including an intermediate layer of a water-swellable colloidal clay, such as pentonite, sandwiched between two layers of sheet material, such as woven or non-woven fabric, or paperboard, wherein at least one one of the sheet material layers has a water-soluble coating material covering substantially the entire outer surface of the sheet material layer. The water-soluble coating is a material that dissolves upon a predetermined water contact period, having a controlled, predetermined water-solubility so that the intermediate water-swellable clay layer is protected against hydration during installation.

摘要： Magnesium oxide is included in a bentonite clay anti-friction composition in an amount of 0.025-0.25% based on the dry weight of the clay to substantially improve the efficiency of underground cable or pipe installation. The anti-friction composition is applied between an outer surface of the cable or pipe and tunnel walls to substantially and unexpectedly reduce the amount of force, e.g., hydraulic pressure, necessary to push or pull the cable or pipe into its intended location within the tunnel. The composition includes a water-swellable colloidal smectite clay, such as bentonite, and magnesium oxide in an amount of 0.025-0.25% based on the dry weight of the clay. In another embodiment, the composition also includes a polymeric fluid loss reduction agent, such as carboxymethyl cellulose to decrease the amount of the clay composition absorbed into the tunnel walls. Soil is extracted underground to form a tunnel and the cable or pipe is forced by a hydaulic jack, into the tunnel. The tunnel walls surrounding the cable or pipe are contacted with the composition comprising a water-swellable colloidal smectite clay and magnesium oxide in an amount of 0.025-0.25% based on the dry weight of the clay, while forcing the cable or pipe into the tunnel.

摘要： A method and apparatus for manufacturing discrete solid particles of hydrocarbonaceous material, such as asphaltenes, in relatively dustless form includes heating the hydrocarbonaceous material, solid at standard conditions of temperature and pressure, to maintain the hydrocarbonaceous material in liquid form, and flowing the liquid hydrocarbonaceous material by gravity as an elongated annular stream into a reservoir of cooling liquid, such as cooling water, to solidify and shatter the annular stream into discrete solid particles in relatively dustless form. The apparatus includes a hopper for collecting a mass of heated liquid hydrocarbonaceous material; a heating source for heating the hydrocarbonaceous material to maintain it in liquid form; and flow channels operatively connected to the hopper at an upper level of the liquid hydrocarbonaceous material for flowing the liquid hydrocarbonaceous material in an elongated annular stream through the flow channel and into the reservoir of cooling water. Discrete solid particles are collected from the cooling water and conveyed to a drying and cooling zone and can be packaged in discrete particles of relatively uniform size in dustless form for transporting for reliquification and use on site in any industry where hydrocarbonaceous heavy materials, such as asphalt, are used.

摘要： A method of extruding clay and then treating the clay with acid to beneficiate the clay for increased capacity of filtration of oil-soluble colorant compounds from oil. The clay is first extruded through one or more die openings to align some of the clay platelets and to form the clay into cylindrical pellets. The extruded clay pellets then are acid treated, either before or after grinding, in an aqueous acid solution to form an acid slurry of the clay. The acid slurry of the clay is agitated for a time sufficient and at a temperature sufficient so that the acid reacts with a portion of the clay and, thereafter, the acid treated clay is separated from the acid solution; the clay then is washed to remove most of the acid solution from the clay; filtered and thereafter dried.
