| 20100297568 | DEVICE FOR PROVIDING A GAS/COMBUSTION AIR MIXTURE FOR A GAS BURNER - The invention relates to a device for providing a gas/combustion air mixture for a gas burner, comprising a fan ( | 11-25-2010 |
| 20110081619 | REGULATING DEVICE FOR GAS BURNERS - Regulating device for gas burners for providing a gas/air mixture, with a mixing device for mixing a gas flow with a combustion air flow and therefore for providing the gas/air mixture, wherein in a gas line which conducts the gas flow at least one gas valve is positioned, which is adjusted in dependence upon a measurement signal of an electric or electronic sensor, wherein the sensor acts on the gas line by a measuring point and wherein a reference pressure prevails on a reference point of the sensor. The mixing device may be formed as a Venturi nozzle, wherein the gas line leads to a mixing region of the Venturi nozzle in which the gas flow and the combustion air flow are mixed, wherein the reference point of the sensor acts on a device in which the reference pressure prevails, and wherein the device may be connected via a connecting line to the Venturi nozzle, that is to say to a region of the Venturi nozzle which lies downstream of the mixing region of the Venturi nozzle. | 04-07-2011 |

| 20090186382 | Preparation of Romidepsin - The invention provides an improved process for preparing romidepsin. The process involves producing, purifying, or storing romidepsin under conditions that prevent the formation of undesired adducts. Purifying romidepsin at an apparent pH lower than approximately 6.0 (e.g., between an apparent pH of 4.0 and 6.0) has been discovered to prevent the reduction of the disulfide bond of romidepsin and the subsequent formation of dimerized, oligomerized, or polymerized adducts. The invention also provides compositions of monomeric romidepsin free of dimerized, oligomerized, or polymerized adducts. | 07-23-2009 |
| 20090209616 | PREPARATION OF ROMIDEPSIN - The invention provides an improved process for preparing romidepsin. The process involves producing, purifying, or storing romidepsin under conditions that prevent the formation of undesired adducts. Purifying romidepsin at an apparent pH lower than approximately 6.0 (e.g., between an apparent pH of 4.0 and 6.0) has been discovered to prevent the reduction of the disulfide bond of romidepsin and the subsequent formation of dimerized, oligomerized, or polymerized adducts. The invention also provides compositions of monomeric romidepsin free of dimerized, oligomerized, or polymerized adducts. | 08-20-2009 |
| 20100093610 | ROMIDEPSIN-BASED TREATMENTS FOR CANCER - The invention provides an improved process for preparing romidepsin. The process involves producing, purifying, or storing romidepsin under conditions that prevent the formation of undesired adducts. Purifying romidepsin at an apparent pH lower than approximately 6.0 (e.g., between an apparent pH of 4.0 and 6.0) has been discovered to prevent the reduction of the disulfide bond of romidepsin and the subsequent formation of dimerized, oligomerized, or polymerized adducts. The invention also provides pharmaceutical compositions of monomeric romidepsin free of dimerized, oligomerized, or polymerized adducts. | 04-15-2010 |

| 20100235154 | Dynamic Connectivity Analysis - Methods, computer-readable mediums, and systems analyze hydrocarbon production data from a subsurface region to determine geologic time scale reservoir connectivity and production time scale reservoir connectivity for the subsurface region. Compartments, fluid properties, and fluid distribution are interpreted to determine geologic time scale reservoir connectivity and production time scale reservoir connectivity for the subsurface region. A reservoir connectivity model based on the geologic time scale and production time scale reservoir connectivity for the subsurface region is constructed, wherein the reservoir connectivity model includes a plurality of production scenarios each including reservoir compartments, connections, and connection properties for each scenario. Each of the production scenarios is tested and refined based on production data for the subsurface region. | 09-16-2010 |
