摘要:
A method and apparatus for maintaining a liquid-frozen solid slush mixture in a vessel at a desired total slush mixture and desired solids content during conditions under which the solids in the slush mixture in the vessel are melting. The method comprises introducing fresh slush mixture to the vessel, while removing liquid from the vessel--both at rates directly proportional to the rate of solids melting in the vessel. The apparatus comprises an auxiliary vessel containing slush mixture and means for transferring slush mixture to the main vessel at one rate, means for transferring liquid from the main vessel to the auxiliary vessel at another rate, and means for controlling the transfer rates in a prescribed manner.

Embodiments of the present invention are generally directed to apparatus and methods for a plasma-processing chamber requiring less maintenance and downtime and possessing improved reliability over the prior art. In one embodiment, the apparatus includes a substrate support resting on a ceramic shaft, an inner shaft allowing for electrical connections to the substrate support at atmospheric pressure, an aluminum substrate support resting on but not fixed to a ceramic support structure, sapphire rest points swaged into the substrate support, and a heating element inside the substrate support arranged in an Archimedes spiral to reduce warping of the substrate support and to increase its lifetime. Methods include increasing time between in-situ cleans of the chamber by reducing particle generation from chamber surfaces. Reduced particle generation occurs via temperature control of chamber components and pressurization of non-processing regions of the chamber relative to the processing region with a purge gas.

This invention relates to a continuous process for the preparation of slush hydrogen by the freeze-thaw technique. The process comprises substantially continuously injecting liquid hydrogen at or near its triple point temperature into a slush hydrogen generator; forming solid hydrogen by removing hydrogen vapor from the slush hydrogen generator; alternately adjusting the pressure in the slush hydrogen generator to a pressure below the triple point of hydrogen and then to a pressure slightly above the pressure at the triple point thereby effecting formation and dispersion of solids in said slush; concentrating the crystalline solid particles in the slush to a level of at least 30%, and preferably from 45 to 60%, by weight; and substantially continuously removing the slush hydrogen from said slush hydrogen generator at a rate such that a substantially constant level of slush is maintained in said slush hydrogen generator.
摘要:
A method for distributing data among automotive dealers, including selecting the data from the dealers, processing the data, and providing the processed data to the dealers while maintaining confidentiality of individual data of each dealer. The selecting of the data further includes collecting data indicating which vehicles are in demand. The data includes at least one of a number of a vehicle's make a dealer has in stock, a vehicle identification number, a vehicle's year, a vehicle's make, a vehicle's model, a vehicle's body style, a vehicle's exterior color, a vehicle's interior color, a vehicle's mileage, a vehicle's retail asking price, a vehicle's transactions cost, a vehicle's reconditioning cost, a vehicle's age, a vehicle's selling price, a vehicle's gross profit, an acquisition need of a vehicle, a selling need of a vehicle, a vehicle's image, a vehicle's turnover rate, or an aggregate of any of the above-listed data. The distributed data may provide optimization on return on investments to the dealers.
摘要:
A tertiary amine, such as a tertiary amine catalyst that is useful in the production of polyurethanes, may undergo decomposition, which may result in the production of undesirable products. These tertiary amines, however, may be treated with a primary amine containing material to reduce the presence of the undesirable products to an acceptable level. Thus, a foam made from a treated tertiary amine will also have a reduction in the presence of the same undesirable products.
摘要:
Methods and compositions are provided for forming a catalyst. In one aspect, the catalyst is formed by mixing at least one tertiary amine with at least one polymer acid. Such catalysts are particularly useful in the polymerization of polyurethane foams.

摘要:
An oxygenated organic liquid product and a fuel gas are produced from a portion of synthesis gas comprising hydrogen, carbon monoxide, carbon dioxide, and sulfur-containing compounds in a integrated feed treatment and catalytic reaction system. To prevent catalyst poisoning, the sulfur-containing compounds in the reactor feed are absorbed in a liquid comprising the reactor product, and the resulting sulfur-containing liquid is regenerated by stripping with untreated synthesis gas from the reactor. Stripping offgas is combined with the remaining synthesis gas to provide a fuel gas product. A portion of the regenerated liquid is used as makeup to the absorber and the remainder is withdrawn as a liquid product. The method is particularly useful for integration with a combined cycle coal gasification system utilizing a gas turbine for electric power generation.

This invention relates to a continuous process for the preparation of slush hydrogen. The process comprises substantially continuously injecting liquid hydrogen at a temperature slightly above its triple point temperature into a slush hydrogen generator; forming solid hydrogen by removing hydrogen vapor from the slush hydrogen generator; fracturing and dispersing surface solid as it is formed into the slush; concentrating the crystalline solid particles in the slush to a level of at least 30%, and preferably from 45 to 60%, by weight; and substantially continuously removing the slush hydrogen from said slush hydrogen generator at a rate such that a substantially constant level of slush is maintained in said slush hydrogen generator.
