Patent CA-2225637-A1 (CA)
Inventor: NADEAU PAUL HENRY
IPC: E21B43/02
Filed: 1996-05-23
Abstract: Procédé de traitement d'une formation rocheuse porteuse d'hydrocarbures. Une suspension colloïdale est introduite dans la formation. Un gradient de potentiel électrique établi au moyen d'une anode (18) et d'une cathode (19) produit des forces osmotiques qui entraînent la stabilisation du colloïde. Ce procédé augmente la stabilité mécanique de la formation, ce qui permet d'extraire des hydrocarbures en éliminant la production d'eau et de sable.

Title: Object bracket holder for concrete forms
Inventor: SCOTT WILLIAM C III
IPC: E04G9/10
Filed: 1996-07-30
Abstract: A individual bracket for holding and securing an object to the surface of a construction form for embedding the object in a settable material, such as concrete, and exposing the face surface of the object in the finished construction. The bracket has an outer configuration formed from a plurality of side and end perimeter members that defines a recess that correspond with the outer configuration of the object. The perimeter members have a flat outer surface extending at right angles to the form and an inwardly extending flange which is parallel and in contact with the form. An upwardly curved inner surface extends from the flange to the outer edge of the flat outer surface which forms one-half of a mold to form a grout line when two brackets are connected together. The actual mold can be any shape desired to provide the various types of grout lines. An object can be held within the bracket by the use of adhesives, coatings, detentes, elastic bands or any other arrangement which will provide secure retainment of the object within the bracket during use. Another embodiment of the bracket includes a relatively rigid base portion and a resilient cap portion. The base portion includes a flange area as well as a partial outer mating surface. The cap portion forms the upper portion of the perimeter member, including the extension of the outer mating surface as well as the rounded extended surface forming the mold area for the grout line. The cap portion is formed from a resilient flexible elastomeric material that can have an outwardly projecting continuous ridge extending around the interior of the bracket.

Patent CA-2252324-A1 (CA)
Inventor: CHEN XUEMIN
IPC: H04N13/239
Filed: 1998-11-03
Abstract: In a stereoscopic video transmission system, where an enhancement layer image is disparity predicted using a lower layer images, the lower layer image is made to more closely match the enhancement layer image by shifting the lower layer image to the right to compensate for inter-ocular camera lens separation. The motion vector search range for disparity prediction is reduced to improve coding efficiency. At an encoder, the optimal offset, x, between the enhancement layer image and the lower layer image is determined according to either a minimum mean error or a minimum mean squared error between the enhancement and lower layer images. The offset x is bounded by an offset search range X. The x rightmost pixel columns of the lower layer image are deleted, and the x leftmost columns of the lower layer image are padded to effectively shift the lower layer image to the right by x pixels to obtain the reference image for use in disparity predicting the enhancement layer image. For arbitrarily shaped images such as VOPs within a frame, the leftmost portion is deleted and the rightmost portion is padded. At a decoder, the offset value x is recovered if available and used to reconstruct the reference frame.
