Patent CA-2969705-C (CA)
Inventor: BENDER ROBERT PAUL
IPC: F16J15/16
Filed: 2015-12-08
Granted: 2020-06-23
Abstract: L'invention porte sur un joint d'étanchéité d'isolateur de palier, lequel joint comprend un joint torique de fermeture et tolère un défaut d'alignement rotor-stator axial, et produit un joint d'étanchéité statique amélioré tout en minimisant une usure de rotation. Une section effilée du stator est chevauchée par le joint torique de fermeture. Quand le rotor est statique, il n'y a pas de défaut d'alignement axial, et le joint torique de fermeture est pressé contre la section effilée, ce qui forme un joint d'étanchéité amélioré. Pendant la rotation du rotor, un défaut d'alignement axial accru éloigne le joint torique de la section effilée, ce qui réduit une usure de rotation. Le stator peut s'étendre horizontalement au-delà de la section effilée et au-dessous du joint torique, de telle sorte que, si le rotor se déplace au-delà d'un défaut d'alignement maximal, il y a une adaptation "ligne sur ligne" entre le stator et le rotor. Le joint d'étanchéité d'isolateur de palier peut comprendre une technologie à labyrinthe, et la section effilée peut comprendre un contour qui permet au joint torique de fermeture de traîner le long de la surface de la section effilée sans accrochages ni collage.

Abstract: L'invention concerne des procédés, des systèmes et un appareil permettant une meilleure récupération du pétrole à l'aide de sensibilisateurs perfectionnés avec des agents d'expansion chimique (CBA pour Chemical Blowing Agent). Le procédé comprend l'irradiation d'ondes électromagnétiques (EM pour ElectroMagnetic). Les sensibilisateurs perfectionnés injectés absorbent l'énergie provenant des ondes EM, ce qui fait augmenter la température. La température élevée active ensuite des agents d'expansion chimique pour aider à la fluidité de l'extraction du pétrole lourd ou de celle du bitume. Les gaz libérés des agents CBA aident également à une valorisation par libération des gaz souhaités, ce qui réduit alors les longues chaînes d'hydrocarbure à une température élevée, ainsi que des catalyseurs.

Abstract: A method of computing a join pattern agnostic aggregate function includes loading source code and parsing the source code to identify different database query operations. In response to the identification of an aggregate function in one of the different database query operations in which records in multiple tables are joined together in a table join, a multiplicity of primary keys are retrieved, each corresponding to a different one of the multiple tables and also an object of one of the tables referenced by the identified aggregate function. An existence of a fan out condition associated with the table join is then computed. On condition that an existence of the fan out condition is not computed a non-fan out sensitive implementation of the aggregate function is invoked with respect to the object. But, otherwise, a different, fan out sensitive implementation of the aggregate function is invoked with respect to the object.
