Abstract: L'invention concerne un procédé de codage prédictif pour image dynamique, pouvant être mise en oeuvre selon deux types de mode de prévision: compensation de mouvement globale et compensation de mouvement locale. Selon ledit procédé, un mot de code MCSEL non nécessaire est réduit autant que possible, même d'un bit, ce qui améliore l'efficacité de compression. Un codeur émet un mot de code MCBPC indiquant la présence ou l'absence de coefficient DCT d'un type de macrobloc et deux blocs de signal de différence de couleur. Ensuite, seulement lorsque le bloc n'est pas un bloc codé intratrame, un codeur émet un mot de code MCSEL indiquant si le macrobloc actuel est prédit par compensation de mouvement globale ou par compensation de mouvement locale.

Abstract: A system and method for identifying a data record associated with a transferred telephone call which is not dependent on the hardware of the particular telephone network and systems involved. In the preferred embodiment, to transfer a telephone call from a first call center to a secon d call center, the application server of the first call center sends a transfe r request which includes the data record associated with the telephone call an d the destination directory number (DDN) to which the call is to be transferre d by the application server of the second call center. The application server of the second call center responds by sending a transfer response which include s a Direct Inward Dialing (DID) telephone number selected from a pool of available members to be used to establish the call transfer. The application  server of the second call center also stores a transfer coordination record which contains the data record, the DID number and the DDN. Upon arrival of the transferred telephone call to the second call center, the application server of the second call center uses the DID number of the transferred call  to access the stored DDN number to redirect the telephone call to the intend ed destination in the second call center and to access the data record and re- associate the data record with the transferred telephone call. Once the transferred call and associated data record have been re-associated the DID number is available for re-use.

Title: Deflector for controlling entry of cooling air leakage into the gaspath of a gas turbine engine
Inventor: VALENTINI VALERIO
IPC: F01D11/00
Filed: 1999-03-22
Granted: 2007-08-21
Abstract: The invention provides a deflector for redirecting cooling air leakage to improve the effi-ciency of a gas turbine engine. A  conventional gas turbine engine includes a forward stator assem-bly and a rotor assembly with an air cooled rotor disc, and a cir-cumferential array of blade re-tention slots. An array of air cooled rotor blades with blade bases are retained in each slot.  The rotor blades are disposed equidistantly about the circum-ference of the rotor disc with a radially extending gap between each adjacent rotor blade. It is the significant detrimental ef-fect of cooling air leakage into these gaps, which is the focus of this invention. The invention relates to providing a deflector, disposed circumferentially on a forward face of the coverplate, for deflecting cooling air leak-age, flowing from the running seal through the cooling air leak-age path, away from the gaps be-tween the blades, onto the out-ward surface of the blade platform, and into the gaspath at an acute angle relative to rearwardly axial flow therein.

Granted: 2002-03-12
Abstract: A heated inclined separation pressure vessel for receiving an oil emulsion. A shell is supported at an oblique angle to horizontal, thereby defining an upper and lower end.      An elongated sleeve extends coaxially through the vessel. A heat pipe bundle extends coaxially through the lower vessel end and sleeve, terminating at an intermediate position within the sleeve. A furnace is provided for heating the heat pipe bundle.      An inlet, adjacent to the upper end, admits emulsion to the elongated sleeve. Gas liberated from the oil is allowed to flow to the upper end of the sleeve and into a gas separator located above the upper end of the vessel. Emulsified water falls towards the lower end of the sleeve and exits the vessel via a water outlet adjacent to the lower vessel head. An oil outlet, adjacent to the upper vessel head removes clean oil from the pressure vessel.
