Patent CA-2242850-A1 (CA)
Title: Method for conducting moving or rolling check shot for correcting borehole azimuth surveys
Inventor: SHIELLS GORDON MALCOLM
IPC: E21B47/022
Filed: 1997-01-10
Abstract: A method is disclosed for correcting the distorting effect of cross-axial magnetic interference on the readings of a well survey tool using a reduced number of measurements and measuring locations. A well survey tool connected to a drill string assembly measures the gravitional and distorted terrestrial magnetic fields at two or more axially displaced locations in an axially extending well bore. The measurements are made from two or more different orientations (tool faces) of the tool about the well axis. Initial values for the tool inclination, azimuth and tool face angle are first determined without correction for the cross-axial magnetic interference introduced by the drill string assembly and the survey tool. Measurements made at each location and tool face are referred to the tool's coordinate system and variations introduced by the different tool face angles are used to estimate the cross-axial interference.

IPC: A63F3/00
Filed: 1999-09-15
Abstract: A card game method similar to common Blackjack uses certain rules of play including dealing a face down card to a player and a dealer while allowing the player to see his card and then place a bet. The player is dealt a second face up card and declaring a winner if both his cards are aces. The player receives further cards seeking to have a total score as close to 21 as possible. If the score is greater than 21 the player looses. If the player does not bust, the dealer is than dealt one or more face up cards until the dealer assumes a bust position whereupon the game is completed and the player is rewarded or until the dealer assumes a standing position whereupon the one with the higher score wins.

Title: Procede permettant la production d'anticorps a des sites specifiques de la rapamycine
Inventor: MALCOLM ANDREW J
IPC: C07K14/765
Filed: 1998-04-09
Abstract: La présente invention concerne la production d'anticorps polyclonaux et monoclonaux à des sites spécifiques de la rapamycine (Sirolimus). La réactivité desdits anticorps les rend particulièrement utiles dans des essais immunologiques permettant le contrôle d'un médicament thérapeutique (TDM). Ces essais immunologiques ou kits TDM peuvent contenir des anticorps polyclonaux et monoclonaux à des sites spécifiques de la rapamycine. Ces kits peuvent également contenir des combinaisons variées d'anticorps polyclonaux, d'anticorps polyclonaux et monoclonaux ou une série d'anticorps monoclonaux. Les immunogènes conjugués de la rapamycine sont préparés en vue de l'immunisation d'un animal hôte et ce, dans le but de produire des anticorps dirigés contre des régions spécifiques de la molécule de la rapamycine. Grâce à la détermination de la région de fixation spécifique d'un anticorps particulaire, on développe les tests immunologiques qui sont susceptibles de distinguer la molécule parent, les métabolites actifs, les métabolites inactifs et d'autres composés immunosuppresseurs présentant une structure similaire. L'invention se rapporte en outre à l'utilisation de divinylsulfone (DVS) en tant que molécule à bras de liaison permettant de former des immunogènes conjugués rapamycine-protéine. Il a été démontré que les conjugués rapamycine-protéine fixés sur la DVS déclenchent des anticorps présentant une plus grande spécificité à la molécule de rapamycine que les conjugués fixés sur le succinate.
