20140341723 | GAS TURBINE VANE INSERT TO CONTROL PARTICULATE DEPOSITION - A guide tube assembly in one embodiment includes a guide tube and a collection impingement feature. The guide tube includes an inlet and at least one first impingement opening. The inlet is configured to direct a cooling air flow along the length of the tube in an inlet direction. The at least one impingement feature is configured to direct at least a portion of the cooling air received via the inlet along a first impingement direction. The collection impingement feature receives the at least a portion of the cooling airflow directed in the first impingement direction, collects particulate matter from the cooling airflow upon impingement of the cooling airflow with the collection impingement feature, and directs the at least a portion of the cooling air flow in a second impingement direction toward a surface of the turbine component to be cooled by the cooling air flow. | 11-20-2014 |
20150033729 | FLOW CONTROL ASSEMBLY AND METHODS OF ASSEMBLING THE SAME - A flow control assembly for controlling cooling flow of a turbine engine is provided. The flow control assembly includes a first flow control device having a first sidewall and a second sidewall. The first sidewall is coupled to a compressor vane and is configured to define a first flow path from a compressor to a turbine vane. The second sidewall is coupled to a compressor vane and is configured to define a second flow path from the compressor to a turbine blade. A second flow control device is coupled to the compressor and includes an orifice device coupled to the compressor vane and a meter device coupled to the orifice, wherein the orifice is configured to direct a cooling flow to the meter device. A controller is configured to control the meter device to facilitate regulating the cooling flow into at least one of the first flow path and the second flow path. | 02-05-2015 |
20150033761 | HEAT TRANSFER ASSEMBLY AND METHODS OF ASSEMBLING THE SAME - A heat transfer assembly for controlling heat transfer of a turbine engine is provided. The turbine engine includes a housing and includes a compressor, a combustor and a turbine located within the housing. The heat transfer assembly includes a flow control device having a sidewall coupled to the turbine, the sidewall is in flow communication with a compressor vane. The sidewall is configured to define a first flow path from the compressor vane to a turbine vane and a second flow path from the compressor vane to a turbine blade. A heat exchanger is coupled to the housing and located between the compressor and the turbine, wherein the heat exchanger is in flow communication with at least one of the first flow path and the second flow path. A fluid supply device is coupled to the housing and in flow communication with the heat exchanger. | 02-05-2015 |

20130323179 | NANOCRYSTALS, COMPOSITIONS, AND METHODS THAT AID PARTICLE TRANSPORT IN MUCUS - Nanocrystals, compositions, and methods that aid particle transport in mucus are provided. In some embodiments, the compositions and methods involve making mucus-penetrating particles (MPP) without any polymeric carriers, or with minimal use of polymeric carriers. The compositions and methods may include, in some embodiments, modifying the surface coatings of particles formed of pharmaceutical agents that have a low water solubility. Such methods and compositions can be used to achieve efficient transport of particles of pharmaceutical agents though mucus barriers in the body for a wide spectrum of applications, including drug delivery, imaging, and diagnostic applications. In certain embodiments, a pharmaceutical composition including such particles is well-suited for administration routes involving the particles passing through a mucosal barrier. | 12-05-2013 |
20150125539 | COMPOSITIONS AND METHODS FOR OPHTHALMIC AND/OR OTHER APPLICATIONS - Particles, compositions, and methods that aid particle transport in mucus are provided. The particles, compositions, and methods may be used, in some instances, for ophthalmic and/or other applications. In some embodiments, the compositions and methods may involve modifying the surface coatings of particles, such as particles of pharmaceutical agents that have a low aqueous solubility. Such compositions and methods can be used to achieve efficient transport of particles of pharmaceutical agents though mucus barriers in the body for a wide spectrum of applications, including drug delivery, imaging, and diagnostic applications. In certain embodiments, a pharmaceutical composition including such particles is well-suited for ophthalmic applications, and may be used for delivering pharmaceutical agents to the front of the eye and/or the back of the eye. | 05-07-2015 |
