    摘要: Processes and apparatuses are provided for continuously harvesting particles from organic solution-laden near-critical and supercritical fluids. Broadly, the processes and apparatuses utilize a filter or separator comprising a thin membrane supported on a sintered stainless steel tube. A feed stream comprising the desired particles, a supercritical antisolvent for the particles (preferably CO.sub.2), and a solvent for the particles, is contacted with the membrane layer of the filter under supercritical conditions for the mixture of antisolvent and solvent. The preferred antisolvents are substantially miscible with the solvent and have a critical temperature of less than 160.degree. C. The desired particles are retained by the filter while the solvent and most of the antisolvent pass through the filter, resulting in separation of the particles from the solvent.

    摘要: Improved methods and apparatus for particle precipitation and coating using near- or supercritical fluid conditions are described. A fluid dispersion having a continuous phase dispersant and at least one precipitatable substance therein is contacted with a supercritical fluid (SCF) antisolvent so as to generate focused high frequency antisolvent sonic waves, breaking up the dispersion into extremely small droplets; the enhanced mass transfer rates between the droplets and the antisolvent causes precipitation of very small particles on the order of 0.1-10 .mu.m. In coating processes, a turbulent fluidized flow of core particles is created using an SCF antisolvent in an enclosed zone. The core particles are contacted therein at near- or supercritical conditions by a fluid dispersion containing a dispersant together with a precipitatable substance. The antisolvent depletes the dispersant and the substance is precipitated onto the fluidized core particles. In another aspect of the invention, a process for preparing and administering a medicament using only a single container is provided. In such method, a fluid dispersion having a dispersant with the medicament therein is contacted with an antisolvent at near- or supercritical conditions within a use container, so as to directly precipitate small particles of the medicament in the container. The antisolvent is then removed and the use container is sealed with the medicament particles therein. Thereafter, dose(s) of the medicament can be withdrawn from the use container and administered to a patient.

    摘要: A deinterleaver device, a method for deinterleaving, an interleaver device, and a method for interleaving are provided. The method for deinterleaving includes: providing a memory and a stream count for a frame; virtually dividing the memory into equal sections, wherein a section count equals the stream count; calculating a write address for a sample of the samples based on a location of the sample in the frame and a correspondence of the location to one of the sections; receiving the sample; and writing the received sample to the write address, wherein the calculating and the write address corresponds to a correct deinterleaving location in one of the sections for the sample.
