| 20100101988 | Portable and autonomous desalination system - The portable and autonomous desalination system is an autonomous reverse osmosis (RO) desalination system utilizing power from a combination of electricity generation and storage sources that include a photovoltaic (PV) unit, a vertical-axis wind turbine (VAWT) unit, and an electricity storage unit. Electric power from PV, VAWT or storage units or a combination of these units is provided, depending upon the availability of sunlight or wind, or for night operation for water desalination using the reverse-osmosis process. The unit is portable, environmentally friendly, self-sufficient and self-sustaining in terms of supplying the electricity and fresh drinking water needs of the typical household. Multiple PV-VAWT-RO desalination units are combined together to provide fresh, clean water and electricity for communities of various sizes. A small-size, straight-bladed vertical axis wind turbine runs at very low wind speeds for urban operation. | 04-29-2010 |
| 20100236200 | System for inertial particles separation - The system for inertial particle separation removes particulate matter, such as sand, from an air stream, such as that drawn into a turbine engine. The system includes first and second walls spaced apart and positioned within a housing of the turbine engine. The first wall is in the form of an airfoil with variable geometry. An annular air flow path is defined between the first and second walls. The air flow path leads inwardly from an ambient inlet and turns to an outlet. A splitter member is positioned between the first and second walls. A scavenge flow path is defined between the splitter member and the first wall. An inlet thereof is in communication with the ambient inlet, and a filtered flow path is defined between the splitter member and the second wall. The splitter member is also in the form of an airfoil having a variable geometry. | 09-23-2010 |

| 20090221811 | PROCESS FOR PREPARING GEMCITABINE AND ASSOCIATED INTERMEDIATES - The present invention provides processes for preparing intermediates useful in the preparation of gemcitabine and other nucleosides, and processes for preparing gemcitabine therewith. Exemplary intermediates include mixtures of D-erythro and D-threo isomers of 3-(hydroxy)-2,2-difluoro-3-(2,2-dimethyldioxolan-4-yl)-propionic acid salts. Also provided is a process for selectively isolating the D-erythro and D-threo isomers of D-erythro and D-threo isomers of 3-(hydroxy)-2,2-difluoro-3-(2,2-dimethyldioxolan-4-yl)-propionic acid salts, and processes for using such isomers in the preparation of nucleoside analogs such as, e.g., gemcitabine, intermediates thereof, and analogs thereof. | 09-03-2009 |
| 20100168431 | NOVEL ISOQUINOLINIUM COMPOUNDS USEFUL IN THE PREPARATION OF CISATRACURIUM AND ASSOCIATED INTERMEDIATES - The present invention provides novel isoquinolinium compounds, methods of producing the isoquinolinium compounds, and methods for converting them into cisatracurium, e.g., cisatracurium besylate. The isoquinolinium compounds of the present invention can be obtained in the form of solids, which can be purified using simple techniques and can be used to afford pure cisatracurium besylate without HPLC purification | 07-01-2010 |
| 20100184988 | PROCESS FOR PRODUCING CISATRACURIUM COMPOUNDS AND ASSOCIATED INTERMEDIATES - The present invention provides processes for producing isoquinolinium compounds, and for converting them into cisatracurium salts, e.g., cisatracurium besylate | 07-22-2010 |
| 20110185796 | CISATRACURIUM DERIVATIVES, PREPARATION AND USES THEREOF - The present invention provides compounds which are useful, e.g., as reference markers for analyzing the purity of cisatracurium and salts thereof, a test method for determining the said purity and processes for preparing reference markers. | 08-04-2011 |
