摘要： Compositions and methods for planarizing or polishing a surface, particularly a semiconductor wafer surface. The polishing compositions described herein comprise (a) a liquid carrier; (b) purified clay; and optional additives, such as (c) a chemical accelerator; and (d) a complexing or coupling agent capable of chemically or ionically complexing with, or coupling to, the metal and/or insulating material removed during the polishing process. The complexing or coupling agent carries away the removed metal and/or silicon dioxide insulator particles, during polishing, to prevent the separated particles from returning to the surface from which they were removed. Also disclosed are methods of planarizing or polishing a surface comprising contacting the surface with the compositions.

摘要： A shaped, water-expandable water-sealing article used for sealing an area between a first section of at least partially cured concrete and a second, adjacent section of substantially uncured concrete. The clay water sealing article is in the shape of a quadrilateral, preferably a trapezoid, and is disposed to bridge an area between the two sections of concrete. Upon hydration of the clay contained within the shaped water sealing article, expansion of the clay creates expansion forces extending from a corner of the article that is surrounded by the uncured concrete, wherein the corner has an included angle greater than 90.degree., preferably at least 100.degree.. The expansion force developed by the expansion of the shaped water sealing article are absorbed by a substantially increased area of the uncured concrete as compared to expansion forces resulting from a clay-based water seal having a 90.degree. included angle at the corner(s) surrounded by the uncured concrete.

摘要： A method of manufacturing a water barrier fabric, in flexible or rigid form, and articles manufactured thereby, formed by dispersing a water-absorbent material, in powdered or granular form, among a mass of fibers during the formation of a loose mat of said fibers, to homogeneously disperse the powdered or granular water-absorbent material above, below and on each side of the fibers forming the mat, and thereafter densifying and structurally consolidating the mat, to secure the fibers in position surrounding and entrapping the water-absorbent material, such as by sewing, quilting, needle punching or otherwise bonding the fibers into a consolidated, structurally secure fabric at least partially filled with the powdered or granular water-absorbent material. In a preferred embodiment, one, or both, major surfaces of the fabric is coated with a water-insoluble adhesive to substantially increase the tensile strength of the fabric and to prevent shifting of fibers when installed on sloping surfaces.

摘要： A composition and method of absorbing animal dross. In one embodiment, the composition comprises discrete particles (about 50 microns to about 3350 microns, preferably about 600 microns to about 3350 microns in size) of a non-compacted water-swellable bentonite clay that effectively absorbs animal dross and simultaneously agglomerates into a sufficiently large and stable mass, thereby permitting physical separation of the soiled and wetted water-swellable bentonite clay particles from discrete particles of the unsoiled and unwetted water-swellable bentonite clay even after partial drying of about 1 to about 24 hours at room temperature, without substantial sticking to animal paws and fur. In another embodiment, the composition comprises discrete particles of a combination of non-compacted water-swellable sodium bentonite clay and calcium bentonite clay that effectively absorbs animal dross and simultaneously agglomerates into a water-dispersible but physically stable mass, thereby permitting physical separation of the soiled and wetted bentonite clay particles from discrete particles of the unsoiled and unwetted water-swellable bentonite clay, and has sufficient water-dispersibility for disposal through a household plumbing or sewer conduit without clogging.

摘要： A method of treating a water-swellable clay after the clay has been mined and dried. After the common initial drying of the clay to a moisture content of 12% or less, the clay is re-wetted to a moisture content of more than 12% by weight, preferably at least about 15% or more, based on the dry weight of the clay, then redried to a moisture content of 12% by weight or less, based on the dry weight of the clay. This re-wetting and re-drying processing of a dried clay unexpectedly improves the water absorbency, and viscosity properties; increases the effectiveness of the clays as binders in sand molds and iron ore pelletizing; unexpectedly increases the rheology properties of the clays for oilwell drilling fluids, and lost circulation fluids, and as a suspending agent in the cosmetics and pharmaceutical industries; improves the binding characteristics of the clays to act as a binder for iron ores, such as taconite, and sand molding (foundry industry); and provides unexpectedly increased water absorption in forming water-swellable clay-based water barriers.
摘要翻译：在开采和干燥粘土之后处理水溶胀性粘土的方法。在将粘土通常初始干燥至含水量为12％以下之后，基于干重将粘土再润湿至大于12重量％，优选至少约15重量％以上的含水量的粘土，然后基于粘土的干重重新进行含水量为12重量％以下的水分含量。这种干燥粘土的再润湿和再干燥处理意外地提高了吸水性和粘度特性; 提高粘土在砂模和铁矿石造粒中的有效性; 意外地增加了油井钻井液，流失液以及作为化妆品和制药行业悬浮剂的粘土的流变性能; 提高粘土作为铁矿石粘结剂的结合特性，如铁粉，砂型（铸造业）; 并且在形成水溶胀性粘土基水屏障时提供意想不到的增加的吸水率。

摘要： A container having four vertical sides, a top side and a bottom side, the six sides being connected to form a cube. The six sides are joined at the edges of the cube, and the juncture of one vertical edge with two upper edges forms a slanted surface. A pouring spout is mounted on the slanted surface and is inset from the planes of the adjacent sides so that it does not interfere with nesting and stacking. A handle is attached to the top side, at approximately its center, for carrying purposes, the handle being foldable to a flat position to facilitate stacking. The container is formed by cutting a blank from a flat sheet of relatively stiff material, and folding the blank along creases to form a closed container. The top and four sides are folded and sealed first, the pouring spout is installed, the container is filled through the open bottom side, and then the bottom side is folded and sealed.

摘要： A new and improved carbon sand and a method of treating a petroleum fluid coke, having a spherical or ovoid particle shape and a size suitable for a core or mold surface in the foundry industry, by heating or roasting the carbon particles at a temperature in the range of about 1000.degree. F. to about 1500.degree. F., particularly about 1200.degree. F. to about 1400.degree. F., for a time sufficient to volatilize from the carbon particles substantially all of the organic contaminants volatilizable at the roasting temperature, and a method of casting molten metal against the heat treated carbon particles, combined with a suitable binder, to form cast metal parts. The carbon sand also is useful in forming shell molds and shell cores and otherwise using the carbon sand to replace other molding and coremaking sands used in any of the various molding and coremaking processes with any of the various binder systems practiced by the foundry industry.
