Patent CA-2179335-A1 (CA)
Inventor: TAYLOR THOMAS ALAN
IPC: B24C1/00
Filed: 1996-06-18
Abstract: A liquid jet is employed to roughen the surface of a substrate so as to enable a subsequent thermal  spray coating material to adhere tightly to the surface.   The substrate is preferably a superalloy that is either nickel, titanium or cobalt based.  The method initially provides a high pressure liquid jet and moves the liquid jet across the substrate surface at a rate so as to deliver liquid to the surface in a range of amounts of at least approximately 0.7 kg/cm2 to approximately 5.5 kg/cm2.  The high pressure liquid jet is preferably provided from a reservoir that is maintained at a pressure in the range of approximately 28 ksi to 52 ksi.  A preferred embodiment employs an initial blast of a grit to the surface of the substrate to remove a  smooth  finish  from  the  substrate,  prior  to  the application of the liquid jet.   The initial grit blast enables substantially lessened pressures and amounts of applied liquid mass to accomplish desired ranges of surface roughening.

Abstract: Les pages de données (305, 310, 315, 320, 325, 330, 335) d'un guide interactif de programmes (IPG) pour la télévision sont transmises selon une fonction de lecture aléatoire qui permet à différents téléviseurs de récupérer certains segments des pages de données en fonction du jour et de l'heure des programmes qu'un téléspectateur souhaite regarder. Une page de données, qui correspond à une image plein écran, est divisée en segments (200) et récupérée par les récepteurs au fil du temps. Les segments sont mélangés pour assurer une séparation optimale dans le flux de données. La séparation optimale correspond à la taille de la mémoire tampon d'entrée du récepteur et de la vitesse de traitement. Les pages peuvent être disposées de manière séquentielle (Fig. 3), ou avec les pages paires séparées des pages impaires (Fig. 5). Les pages sont divisées en un certain nombre de sous-ensembles (640, 680), et, dans les pages de chaque sous-ensemble, les segments sont mélangés selon une fonction aléatoire parfaite pour que les paires de segments adjacents respectifs soient disposées dans un ordre qui maximise un minimum de leur distance inter-segment après mélange. La distance inter-segment minimale de tous les sous-ensembles est utilisée pour déterminer une heure d'arrivée d'inter-segments caractéristique, qui doit être assez importante pour correspondre aux capacités de traitement du récepteur. La taille de la mémoire tampon d'entrée et de la vitesse de traitement des récepteurs requises sont réduites, mais la vitesse d'acquisition de page de données est augmentée pour tous les téléspectateurs.
