Abstract: The invention relates to a method for drying salts with a water of crystallisation content in convective apparatuses that can additionally be indirectly heated. The invention is primarily characterised in that the drying process takes place with a moisture content of the drying gas above a determined level. The gas surrounding the salt particles during the drying process therefore has a specific humidity. In this way, the rate of drying is positively influenced.

Abstract: Systems and methods of recovering solid waste (solid waste brine) from produced water in an oil sands system for the production of oil and other hydrocarbons utilizing a fluidized bed spray granulator system to provide evaporative drying.

Abstract: A process for recovering solid waste from produced water in an oil sands system utilizing a fluidized bed, comprising: transferring an amount of produced water into a solution tank, producing an enriched salt solution in the solution tank, transferring the enriched salt solution using at least one spray nozzle into a fluidized bed of a fluidized bed spray granulator, heating the fluidized bed with a gas, growing granules within the fluidized bed through evaporative drying of salt from the enriched salt solution, extracting the granules from the fluidized bed spray granulator to produce a granulator product, separating at least a portion of the granulator product into at least two fractions, and removing at least a portion of at least one of the at least two fractions from the system as solid waste brine product.

Abstract: Crystalline polymorphs of (3R)-1-(2-methylalanyl-D-tryptophyl)-3-(phenylmethyl)-3-piperidinecarboxylic acid 1,2,2-trimethylhydrazide which are useful as pharmaceutical agents are disclosed. Methods of production and isolation of these polymorphs and pharmaceutical compositions which include these polymorphs and pharmaceutical methods of treatment are also disclosed. The crystalline polymorphs of the present invention are useful as they act directly on the pituitary gland cells to release growth hormone.

Abstract: Example methods, apparatus, and articles of manufacture to monitor audience exposure to media using duration-based data are disclosed. A disclosed example method involves determining a duration of exposure to an information medium based on transaction information associated with access to a public establishment, determining a first duration value based on the duration of exposure, and determining a second duration value indicative of a duration for which the information medium is accessible within the public establishment. The example method also involves determining an exposure performance value based on the first and second duration values indicative of an exposure performance of the information medium.

Abstract: A rotary valve for interposition between and fluid communication of a rotary joint and a rotating cylinder, comprising a valve body having a passageway therethrough which terminates at a first end of the valve body connectable to a rotary joint and at a second end of the valve body connectable to a rotating cylinder, and a valve disposed within the passageway. The valve is movable between a first, opened position, wherein a fluid is communicable through the passageway, and a second, closed position, wherein a fluid is not communicable through the passageway.

Abstract: Disclosed is a method and device for heat-treating plaster which is calcined to form hemihydrate plaster or anhydrite. Calcining to form hemihydrate plaster is carried out in at least one fluid bed region in which the water vapor partial pressure and material temperature are adjusted. The at least one fluid bed region can be followed by a further fluid bed region in which the anhydrite is formed and the water vapor partial pressure and material temperature are also adjusted. In addition, a fluid bed region can be provided for cooling purposes before the product-discharge point.

Abstract: Process for the polymerization of cyclic olefins by photochemical ring-opening metathesis polymerization by irradiation, using catalytic amounts of a heat-stable ruthenium or osmium catalyst which has at least one photolabile ligand, the other coordination sites being occupied by non-photolabile ligands.

Abstract: A process is described for the preparation of photopolymerizable compositions, wherein the photopolymerizable compositions can be photopolymerized by the irradiation of emission lines of differing wavelength from a UV/VIS laser light source, and contain a photopolymerizable compound and at least two photoinitiators, by adjusting the sensitivity to radiation. The ratio between the concentrations of the individual photoinitiators is so adjusted that the composition has virtually the same optical density for the radiation of the different emission lines at which the photoinitiators are effective.
