20140138862 | Process and Apparatus for Making Proppants - A highly efficient process is disclosed for making proppants from generally non-spherical or discretized raw material, such as naturally occurring sand or pelletized refractory material. In one embodiment of the process, the discretized material is heated by a counter-current flow of hot gas in a first Moving Bed Gas-Solids Direct Contact Heat Exchanger (MBGSDCHX). The heated discretized material is then further heated to a transformative temperature by a raw material transformation means to a partially or fully melted state in which the discretized raw material assumes generally spherical shapes. The spheres are then cooled by a counter-current flow of cold gas in a second MBGSDCHX. The cooled spheres are then size-classified for use as proppants. In an alternate embodiment, refractory raw material is melted and then discretized into molten drops. The molten drops are cooled and frozen into generally spherical shapes. The cooled spheres are used as proppants. | 05-22-2014 |
20140210117 | PHARMACEUTICAL COMPOSITIONS OF DISPERSIONS OF DRUG AND NEUTRAL POLYMERS - In one aspect, pharmaceutical compositions comprising dispersions of an acid-sensitive drug and a neutral dispersion polymer are disclosed. The acid-sensitive drug has improved chemical stability relative to dispersions of the drug and acidic polymers. In another aspect, pharmaceutical compositions of low-solubility drugs and amphiphilic, hydroxy-functional vinyl copolymers are disclosed. | 07-31-2014 |

20160023377 | Method for the Production of Polyester Granulates From Highly Viscous Polyester Melts and Also Device for the Production of the Polyester Granulates - The invention relates to a method and device for the direct production of polyester granulate from a highly viscous polyester melt with a polymerisation degree of 132 to 165, as well as the granulates formed thereform. In the method, the highly viscous polyester melt is subjected to a pre-drying and drying/degassing after a hot cutting method. Hot cutting is implemented at water temperatures of 70° C. to 95° C. and with a liquid to solid ratio of 8 to 12:1. | 01-28-2016 |
20160144328 | METHOD OF FORMING POLYELETROLYTE COMPLEX CAPSULES - Polyelectrolyte complex microcapsules are prepared by a novel template- and surfactant-free method. The microcapsules are produced spontaneously by ultrasonically spraying a solution of complex into a hot water reservoir which enhances diffusion and relaxation of polymer. The size and wall thickness of microcapsules are precisely controlled. Encapsulation of polymers and nanoparticles by mixing them with polyelectrolyte solutions is demonstrated. | 05-26-2016 |
