20150219179 | VIBRATION ISOLATOR WITH ZERO STIFFNESS WHOSE ANGLE DEGREE OF FREEDOM IS DECOUPLED WITH SPHERICAL AIR BEARING - A vibration isolator with zero stiffness whose angle degree of freedom is decoupled with a spherical air bearing has a main body, in which a sleeve and a lower mounting plate, a piston cylinder and the sleeve are both lubricated and supported with air bearing surfaces respectively, and the angle degree of freedom between a upper mounting plate and the lower mounting plate is decoupled with a spherical air bearing; a position close-loop control system comprising voice coil motors, displacement sensors, limit switches, a controller and a driver is introduced, and the relative position between the upper mounting plate and the lower mounting plate is precisely controlled. | 08-06-2015 |
20150219180 | MAGNETICALLY SUSPENDED AND PLANE-DROVE VIBRATION ISOLATOR - A magnetically suspended and plane-drove vibration isolator with zero stiffness comprises an upper mounting plate, a lower mounting plate and a main body. A sleeve of the main body is lubricated and supported against the lower mounting plate by a magnetically suspended planar motor. A piston cylinder fitted in the sleeve is lubricated against the sleeve by a cylindrical air bearing surface. The angle degree of freedom between the upper mounting plate and the lower mounting plate is decoupled by a spherical air bearing. A position close-loop control system is formed to precisely control the relative position between the upper mounting plate and the lower mounting plate. | 08-06-2015 |

20080227963 | Process for preparing glycopeptide phosphonate derivatives - Disclosed are processes for preparing glycopeptide phosphonate derivatives having an amino-containing side chain. Several of the process steps are conducted in a single reaction vessel without isolation of intermediate reaction products, thereby generating less waste and improving the overall efficiency and yield of the process. | 09-18-2008 |
20090069534 | Hydrochloride salts of a glycopeptide phosphonate derivative - Disclosed are hydrochloride salts of telavancin having a chloride ion content of from about 2.4 wt. % to about 4.8 wt. %. The disclosed salts have improved stability during storage at ambient temperatures compared to other hydrochloride salts. Also disclosed are processes for preparing such salts. | 03-12-2009 |
20110060122 | PROCESS FOR PREPARING GLYCOPEPTIDE PHOSPHONATE DERIVATIVES - Disclosed are processes for preparing glycopeptide phosphonate derivatives having an amino-containing side chain. Several of the process steps are conducted in a single reaction vessel without isolation of intermediate reaction products, thereby generating less waste and improving the overall efficiency and yield of the process. | 03-10-2011 |
20140274877 | HYDROCHLORIDE SALTS OF AN ANTIBIOTIC COMPOUND - The present invention relates to a compound of formula I: | 09-18-2014 |
20140275554 | CRYSTALLINE FORM OF A SUBSTITUTED THIAZOLYLACETIC ACID TRIETHYLAMINE SALT - The invention relates to a crystalline form of a triethylamine salt of (2Z)-2-(2-amino-5-chlorothiazol-4-yl)-2-(3-N-tert-butoxycarbonylaminopropoxyimino)acetic acid. The invention also relates to processes and intermediates for preparing the crystalline form. The crystalline form is useful as an intermediate for preparing cross-linked glycopeptide-cephalosporin antibiotics. | 09-18-2014 |

20120143911 | RECOMMENDATIONS BASED ON TOPIC CLUSTERS - A system and method for developing a user's profile based on the user's interaction with content items. A module on the client rendering the content items or the service including the content items tracks the user's interactions with the content items and transmits the tracked data to a user analysis module. The user analysis module determines the topics associated with the interacted upon content items. The user analysis module then selects the topics for the user's profiles based on the received tracked data and the associated topics. The selected topics are mapped to topic clusters and the topic clusters are stored in association with the user profile. Recommendations for a user are made based on the topic clusters associated with the user's profile. | 06-07-2012 |

20090086874 | Apparatus and method of elastic buffer control - A method, system, and apparatus for synchronizing an asynchronous data transmission between a transmitter and a receiver are presented. For example, an elastic buffer can include a symbol storage coupled to receive transition data from a transmitter and to store the transition data in a plurality of addressable symbol storage elements; a write clock domain, which operates at a recovery clock, for selecting a symbol storage element of symbol storage to store the transition data, determining whether a SKIP ordered set has occurred, and deleting a SKIP symbol of the SKIP ordered set based on the determination to prevent the deleted SKIP symbol from being stored in symbol storage; and a read clock domain, which operates at a local clock, for selecting a symbol storage element of the symbol storage to retrieve the transition data as receiver data, determining whether a SKIP ordered set is occurring, adding a SKIP symbol to the receiver data based on the determination; and providing the receiver data to a receiver. | 04-02-2009 |
