Abstract: Des opérations de drainage par gravité au moyen de vapeur (SAGD) peuvent comprendre linjection dun mouillant à leau pour améliorer la mouillabilité à leau de surfaces minérales définissant des microcanaux de la matrice de réservoir. Les produits chimiques ont traditionnellement été sélectionnés en fonction de laccroissement de la mobilité de la phase huileuse et de la réduction de la tension interfaciale entre les phases huileuse et aqueuse, mais la sélection en fonction de la mouillabilité à leau des microcanaux dans la matrice de réservoir peut faciliter laccroissement de la mobilité de leau dans cette matrice et, par conséquent, améliorer le procédé démulsification du bitume dans leau. Des méthodes de sélection des produits chimiques, des procédés de récupération dhydrocarbures, dont le SAGD basse pression, et diverses autres techniques sont décrits.

Abstract: Dans la présente invention, des disques à ressort sont verrouillés en rotation sur le mandrin entre des paires de bagues d'actionnement qui présentent une saillie circonférentielle. Lors de l'application d'une libération de force axiale d'une force stockée du fait d'une flexion, la saillie vient en prise avec une partie inclinée du disque à ressort et déplace la partie inclinée vers une orientation plus verticale. En variante, une libération d'une force stockée du fait de la flexion donne lieu au même résultat. Des fentes dans le disque à ressort permettent une croissance irrégulière pour se conformer aux irrégularités de surface d'une surface environnante. Les disques peuvent servir d'éléments d'ancrage, de centreurs ou de supports pour un élément d'étanchéité dans une garniture d'étanchéité. Des extrémités de doigts présentent des raidisseurs pour améliorer la résistance. Les disques peuvent être empilés séparément ou ensemble et orientés dans la même direction ou dans des directions opposées. Ils peuvent délivrer une force axiale lorsqu'ils sont empilés et poussés pour être aplatis puis libérés.

IPC: H04N21/845
Filed: 2018-12-11
Granted: 2023-02-14
Abstract: In various embodiments, a shot collation application causes multiple encoding instances to encode a source video sequence that includes at least two shot sequences. The shot collation application assigns a first shot sequence to a first chunk. Subsequently, the shot collation application determines that a second shot sequence does not meet a collation criterion with respect to the first chunk. Consequently, the shot collation application assigns the second shot sequence or a third shot sequence derived from the second shot sequence to a second chunk. The shot collation application causes a first encoding instance to independently encode each shot sequence assigned to the first chunk. Similarly, the shot collation application causes a second encoding instance to independently encode each shot sequence assigned to the second chunk. Finally, a chunk assembler combines the first encoded chunk and the second encoded chunk to generate an encoded video sequence.

Title: Portioning device with interchangeable scoops
Inventor: EIKELENBERG RALPH F E
IPC: A47J43/28
Filed: 2021-06-04
Granted: 2023-11-07
Abstract: A portioning device includes an integrated handle, actuating lever, and rack with teeth, with the handle having an aperture at the top. The rack is formed to be easily placed, and retained, in an initial position for assembly. One or more scoops are provided which may each be detachably connected the handle top end. A wiping blade may be detachably connected to the scoop for free rotation within the scoop. The wiping blade includes a shaft having a number of gear teeth, together with a camming surface leading to the first tooth on the shaft. Insertion of the scoop and wiping blade shaft into the handle aperture results in the first rack tooth acting as a camming surface and rotating the wiping blade to the proper clocking position with the first tooth of the shaft engaged with the first tooth of the rack. In this manner the number of component parts is reduced significantly, while at the same time allowing for re-use of the handle with the various interchangeable scoops.
