20100293161 | AUTOMATICALLY AVOIDING UNCONSTRAINED CARTESIAN PRODUCT JOINS - Database queries for retrieving data from database tables, that do not impose any constraints on the data to be retrieved, result in Cartesian product joins. Such unconstrained database queries when executed impose a significant load on resources, take a long time to execute, and may produce inaccurate and misleading results. Functionality can be implemented to reduce the amount of data retrieved by constraining database queries resulting in Cartesian product joins before they are executed. This can be done by leveraging referential constraints that depict relationships between the tables to be joined to limit the results produced by executing the Cartesian product join. Automatically detecting and preventing execution of Cartesian product joins by leveraging the referential constraints can reduce the processing load on the machine, reduce the time spent in executing the database query, minimize the number of query results, and prevent inaccurate results from being displayed. | 11-18-2010 |

20100067402 | MIDDLEWARE COMPONENTS FOR BUNDLING SERVICE INVOCATIONS - A machine readable medium having instructions stored thereon to cause the machine to execute a method is provided. The method includes analyzing a received client request and available statistics to determine whether the request is likely to succeed and whether the request should be bundled with other requests. If the request is determined to not be likely to succeed, an error message is outputted to the client. If the request is determined to be likely to succeed but should not be bundled with other requests, a first service provider relevant to the request is invoked. If the request is determined to be likely to succeed and should be bundled with other requests, the request is bundled with the other requests and, subsequently, the first and/or a second service provider relevant to the bundled requests is invoked. The available statistics are then updated. | 03-18-2010 |

20130345296 | Compositions Comprising a Taxane for Coating Medical Devices - The present invention relates a pharmaceutical composition comprising a taxane and an inhibitory compound capable of inhibiting the enzyme acetaldehyde dehydrogenase e.g. disulfiram. The pharmaceutical compositions of the invention can be used to coat medical devices such as implants. Such implant can be an expansible hollow part, having at least one opening, which consists of an elastic biocompatible material that comprises elongated micro-cavities in its surface. Medical devices coated with a pharmaceutical composition of the invention exhibit an enhanced transfer of taxane from the surface of said medical device into the target tissue. | 12-26-2013 |

20130343940 | HYDRAULIC FEED DEVICE AND HYDRAULIC SYSTEM - A hydraulic feed device may include a pendulum-slide cell pump having an internal rotor drivingly connected to an external rotor via pendulum slides. A hydraulic positioning device may have a positioning element for changing an eccentricity between the internal rotor and the external rotor. The positioning element may be preloaded by a spring device for setting a maximum eccentricity. The positioning device may have a first pressure adjusting and a second pressure adjusting chamber for adjusting the positioning element. The first pressure adjusting chamber may be permanently hydraulically connected to a pressure side of the pendulum-slide cell pump and configured to hydraulically counteract the spring device. The second pressure adjusting chamber may be controlled via a control valve and hydraulically connected to the pressure side of the pendulum-slide cell pump and configured to hydraulically counteract the spring device. | 12-26-2013 |
