Patent CA-2433233-A1 (CA)
Inventor: MARTIN MICHAEL KENT
IPC: B29C49/00
Filed: 2003-06-25
Abstract: A process for extrusion blow molding an article, and an extrusion blow-molded article, in which a solid radially outwardly extending flange is blown into the tubular side wall of the article. A circumferentially extending groove is formed in the inner surface of the mold that molds the tubular side wall of the article. A parison of molten thermoplastic material is extruded and the parison is inflated by blowing to blow the parison against the walls of a mold. During inflation, the groove is filled by the molten thermoplastic material. The material that filled the groove forms a solid radially outwardly extending flange molded to the tubular side wall of the article. A portion of the article extending above the flange is severed in a single cutting step to form an article having an outward flange at its top end.

Title: Diametric expansion measurement
Inventor: DROUIN MARCELLIN
IPC: G21C1/20
Filed: 2003-11-14
Abstract: This paper describes a method for measuring the diametral expansion of the pressure tubes at Gentilly-2 nuclear generating station. The aim is to describe the solution, the calibration tools, and the analytical methods developed for the project. To measure the diametral expansion of the pressure tubes, Hydro-Québec modified the SLARette device and integrated a new module called MED. The measurement system is made up of three parts: 1. An inspection head, the MED (Hydro-Québec) module, which has five ultrasonic probes that determine the distance between the inspections head and pressure tube.    Measurements are always done under water and they are used to determine the diameter and thickness of the pressure tubes. 2. A Tomoscan III acquisition system by R/D Tech to scan the five probes and save the data in an A-scan file. 3. An Analytical software: LogaMED (Hydro-Québec). The advanced delivery machine (ADM) equipped with a SLARette device is primarily an axial inspection system.  The ADM and SLARette device are not capable of performing an axial/rotational inspection and have no centering system. However, measuring the diametral creep requires spiral scanning and a centered tool. A method that would allow the walls of the tubes to be measured in an uncentered way and to recalculate the diameters as if the device were centered has been designed. An automatic analytical software program (LogaMED) was designed to perform the calculation. LogaMED reads A-scan file data and provides the user with information on diameter and thickness. Two methods can be used to determine the diameter. The first consists in moving lengthwise through the tube. Several passes can be done at different angles and the results compiled in LogaMED. The second method is used to measure the diameter at every angle with an angular displacement (360° rotation). Two of the main problems that had to be resolved were the calibration of the calculation parameters and the determination of measurement uncertainties. We were able to measure the diameters under different conditions such as temperature variations and changes in the aqueous environment (light water and heavy water). In fact, a model was used to develop the calculations for recentering the diameter. Keywords: ultrasonic testing, fuel channel inspection, fuel channel diameter creeping.

Title: System and method for video error concealment
Inventor: FLOTT RICK
IPC: H04N19/895
Filed: 2002-08-23
Abstract: The present invention provides, in one embodiment, a system and method for concealing video errors. The system encodes, reorders, and packetizes video information into video data packets for transmission over a communication network such that the system conceals errors caused by lost video data packets when the system receives, depacketizes, orders, (915) and decodes the data packets. In one embodiment, the system and method encodes and packetizes video information, such that adjacent macroblocks are not placed in the same video data packets (925) . Additionally, the system and method may provide information accompanying the video data packets to facilitate the decoding process. An advantage to such a scheme is that errors due to video data packet loss are spatially distributed over a video frame. Thus, if regions of data surrounding a lost macroblock are successfully decoded, the decoder may predict motion vectors and spatial content with a higher degree of accuracy, which leads to higher video quality.
