20150295848 | DYNAMIC DATA SERVER NODES - A system of dynamically-instantiated data server components provides access to a data repository. Different data server components are assigned to different data collections in the repository. A distribution component receives messages and, based on data collection identifiers associated with the messages, routes the messages to corresponding data server components. Based on the messages, the data server components perform data operations with respect to their corresponding data collections. Data server components may be terminated when their assigned data collections are not in use. When an incoming message is associated with a data collection for which no data server component exists, the distribution component dynamically instantiates a new data server component for the data collection. In an embodiment, data server components make working copies of their respectively assigned data collections in a high-speed memory. By terminating inactive data server components, the system makes room in the memory for active data collections. | 10-15-2015 |

20120248704 | FILM RIDING SEAL FOR TURBINES - An seal is described for a turbine with a first sealing surface mounted on a stationary part of a turbine and a second sealing surface mounted on a rotating part of the turbine, the surfaces being structured such that in operation the thin film of a fluid medium is generated between the two surfaces reducing contact and/or leakage with at least one of the first or second sealing surface mounted such that it is subject to a retracting force which opens the seal while stationary or at slow rotation speeds of the turbine and subject to a force counteracting the retracting force at operational rotation speeds of the turbine. The surface of the sealing face may incorporate patterns straight or helical in nature to help induce the fluid into the gap and maintain the fluid film. | 10-04-2012 |
