Abstract: Amine-aldehyde resins are disclosed for removing a wide variety of solids and/or ionic species from the liquids in which they are suspended and/or dissolved. These resins are especially useful as froth flotation depressants, for example in the beneficiation of value materials (e.g., bitumen, coal, or kaolin clay) to remove impurities such as sand. The resins are also useful for treating aqueous liquid suspensions to remove solid particulates, as well as for removing metallic ions in the purification of water.

Abstract: Modified resins are disclosed for removing a wide variety of solids and/or ionic species from the liquids in which they are suspended and/or dissolved. These modified resins are especially useful as froth flotation depressants in the beneficiation of many types of materials (e.g., mineral and metal ores), including the beneficiation of impure coal comprising clay impurities, as well as in the separation of valuable bitumen from solid contaminants such as sand. The modified resins are also useful for treating aqueous liquid suspensions to facilitate the removal of solid particulates, as well as the removal of metallic ions in the purification of water. The modified resins comprise a base resin that is modified with a coupling agent, which is highly selective for binding to solid contaminants and especially siliceous materials such as sand or clay.

At least a portion of the gas system is positioned above the deposition chamber. The gas system includes a mixer configured to mix a plurality of gas streams. A transfer member is in fluid communication with the mixer and the gas inlet. The transfer member comprising a pair of horizontally divergent walls configured to spread the gas in a horizontal direction before entering the gas inlet.

Abstract: A semiconductor wafer support pin assembly. A susceptor has at least three support pins configured to raise a wafer above the top surface of the susceptor. Each support pin includes and upper pin and a lower pin, which lock together by means of a quick-release mechanism in the form of a bayonet mount. The upper pin is made of a non-metallic material, such as polybenzimidazole. The susceptor is driven up and down by a lifting mechanism, driven by an electric motor or pneumatic cylinder. The susceptor moves up and down, relative to the support pins.

Abstract: Amine-aldehyde resins are disclosed for removing a wide variety of solids and/or ionic species from the liquids in which they are suspended and/or dissolved. These resins are especially useful as froth flotation depressants in the separation of bitumen from sand and/or clay or in the beneficiation of clay (e.g., kaolin clay) from an impure clay-containing ore. The resins are also useful for treating aqueous liquid suspensions to remove solid particulates, as well as for removing metallic ions in the purification of water.

Abstract: A method and system is described for introducing chemistry into a high pressure fluid for treating a substrate. In particular, the method includes dispersing the chemistry throughout the volume of high pressure fluid in order to promote mixing of the two or more fluids, while the high pressure fluid is circulating through a high pressure processing system.

Abstract: A method for the catalytic conversion of codeine, morphine or analogs thereof into hydrocodone, hydromorphone or analogs thereof utilizing a transition metal complex of a tertiary phosphine halide as catalyst.

Abstract: A processing system utilizing a supercritical fluid for treating a substrate is described as having internal members having a coating. For example, the coating in internal members can reduce particulate contamination during processing. Additionally, a method for using the processing system is described.

Abstract: Disclosed are compositions and methods for decreasing the viscosity and/or cohesiveness of and/or increasing the liquefaction of excessively or abnormally viscous or cohesive mucus or sputum. Also disclosed are compositions and methods for inhibiting elastase in a patient. The compositions contains a compound containing a dithiol active-site in reduced state and optionally further contains a reducing system.

Abstract: A substantially infinitely water-dilutable resole (P:F) resin solution useful for preparing an aqueous binder composition and the related method of its use for making glass fiber products, especially fiberglass insulation.

Abstract: A method for the catalytic conversion of codeine, morphine or analogs thereof into hydrocodone, hydromorphone or analogs thereof utilizing a transition metal catalyst of the formula [M(PR3R4R5)nXm]p; wherein R1 is H, alkyl, aryl or acyl; M is a Group VIII transition metal; R3, R4 and R5 are selected from the group consisting of alkyl, aryl, alkoxyl, phenoxyl and combinations thereof; X is a halide or an anion; n is 1, 2, 3 or 4; m is 1 or 2; and p is at least 1.

Abstract: The present invention is concerned with a method for the extraction of magnesium from magnesium-containing materials such as magnesite, dolomite and silicates materials like serpentine residues, products from the amphibole or pyroxene group. The magnesium-containing material is first leached in at least one leaching reactor, and subsequently submitted to a series of neutralizing steps in separate reactors under controlled pH and oxydo-reduction potentials. The slurry produced is filtered to produce a substantially pure magnesium chloride solution containing less than 1 ppm of each contaminant present therein.

Abstract: A gasket for a crown cap to be used on a carbonated beverage, especially a twist-off crown or for a bottle which is to be pasteurized, is formed of a thermoplastic material, which is preferably free of polyvinyl chloride, and which contains a hydrogenated copolymer of styrene and a conjugated diene, or a functionalized derivative thereof. The material is resistant to heat, and provides a gasket with advantageous sealing properties.

Abstract: An apparatus for efficiently heating a wafer within a CVD environment isolates the heating element of the apparatus from the CVD environment and includes a susceptor body defining a sealed space therein for containing the heating element and a surface coupled to the heating element for supporting and heating the wafer. The susceptor space is sealed from the CVD environment and is vacuumed to a first pressure. Heating gas is delivered through a space extending through the susceptor body which is sealed from the susceptor space containing the heating element and is vacuumed to a second pressure which is preferably less than the CVD reaction pressure to vacuum clamp a wafer to the susceptor. The heating gas delivery space is formed by an elongated sheath surrounding a hollow wafer lift tube and the sheath is sealed at one end to the backplane of the susceptor and at the other end to the tube. The wafer lift tube moves up and down within the sheath to lift a wafer.

Abstract: Persons with back problems have trouble putting on their stockings without experiencing some back pain or stress. An apparatus is provided for enabling the person to put on his stockings without bending or stooping; the person thereby avoids the back pain associated with such bending. An arcuate hollow form is releasably attached to the upper edge of a stocking by clamp elements located at spaced points on the hollow form. Elongated straps extend from the clamping points, such that the person can pull the hollow form over the foot and up onto the leg without bending or stooping.
