Patent CA-2233707-A1 (CA)
Title: Integrated magnetic levitation and rotation system
Inventor: STANTON WILLIAM
IPC: H02K19/10
Filed: 1996-10-18
Abstract: A rotary motor and a rotary magnetic bearing are integrated in a compact assembly (10) that is contactless. A stator assembly (16) surrounds a ferromagnetic rotor (18) with an annular air gap (20) which can accommodate a cylindrical wall (12e), e.g. of a chamber, for semiconductor wafer processing. The stator assembly (16) has a permanent magnet (38) or magnets sandwiched between vertically spaced magnetic stator plates (36) with plural pole segments (36a). The rotor is preferably a ring of magnetic stainless steel with complementary pole teeth ( 18c). The stator assembly levitates and passively centers the rotor along a vertical axis and against tilt about the either horizontal axis (26, 28), provides a radial position bias for the rotor, and establishes a motor flux field at the rotor poles. Polyphase coils (40) wound on the stator plates (36) produce a rotating flux field that drives the rotor as a synchronous homopolar motor. A rotor without pole teeth allows operation with an asynchronous inductive drive. A controller (54) energizes control coils (42) wound on each stator pole segment (36a) in response to a sensed physical position of the rotor. The control coils (42) provide active radial position control and can actively damp tip and tilt oscillations that may overcome the passive centering.

Patent CA-2241596-A1 (CA)
Inventor: RYDBECK NILS
IPC: H04B7/185
Filed: 1996-12-23
Abstract: A method and system for increasing the signal margin of a radiocommunication link to provide a short message service which is reliable, even under nonideal conditions. According to the method, short alphanumeric messages can be transmitted over the broadcast control channel of a digital radiocommunication link, or another communication channel consisting of one or more slots from successive frames in a TDMA communication link. An increase in transmission power is used in combination with repetition to increase effective signal margin without complications in the mobile unit design, significant delay, or co-channel interference. Where a more significant increase in signal margin is desired, when a longer message is required, or for voice messages, the message may be stored and the mobile unit alerted of the message.

Patent CA-2243218-A1 (CA)
Inventor: JEAN NELSON
IPC: H04L47/765
Filed: 1998-07-14
Abstract: The invention provides a method for communication between a plurality of stations in a communication network using media access protocol, in which medium access is granted to stations obtaining a successful reservation of the medium and in which data transmission verification is performed by the protocol within the reservation.  In the method a station sends a request message on the communication medium for a reservation of the medium to a recipient station in the network. The recipient station sends a reservation confirmation message back to the sending station which receives it and responds to the reservation confirmation message by sending an ordered sequence of data frames to the recipient station. After sending the ordered sequence of data frames the sending station sends an end of transmission message to the recipient station, which replies by sending back an end of transmission confirmation identifying the number of frames received in their original sequence. If the number is not correct remedial action can be taken by the sending station to resend missing data.  Address conflict resolution is also provided by another aspect of the invention. The invention has embodiments which handle unicast and groupcasting transmissions.

Title: Synthese de cycloalkyldiarylphosphines

IPC: C07F9/50
Filed: 1997-03-24
Abstract: En faisant réagir certains cycloalcanes chloro-substitués, à empêchement stérique partiel, avec des diarylphosphides de sodium et/ou de potassium dans un milieu réactionnel éther, on obtient non seulement des cycloalkyldiarylphosphines utiles, mais, de plus, le cycloalcane chloro-substitué ne subit pas de réaction notable avec l'aryle sodium et/ou l'aryle potassium coproduit tel qu'il est formé. De plus, ce procédé permet d'éviter ou au moins de réduire considérablement l'interaction avec ou sans clivage des milieux réactionnels éther cyclique tels que le tétrahydrofuranne. Ce procédé permet donc d'améliorer à la fois le rendement et la qualité du produit de cycloalkyldiarylphosphite. Un procédé en deux étapes effectué dans un milieu réactionnel éther est également décrit. Dans la première étape, le réactant de diarylphosphate de sodium et/ou de potassium est obtenu par réaction entre le sodium et/ou le potassium et triarylphosphine.

Filed: 1997-05-13
Abstract: A system for spectroscopic imaging of bodily tissue in which an optical storage element (1500) and a charged coupled device (CCD) are used to accurately image selected tissue. An x-ray source generates x-rays which pass through a region of a subject's body, forming an x-ray image which reaches the optical storage element (1500). The optical storage element (1500) reradiates a spatial intensity pattern corresponding to the image, the pattern being detected by a CCD sensor. The image is digitized by the sensor and processed by a controller before being stored as an electronic image. Each image is directed onto an associated respective CCD or amorphous silicon detector to generate individual electronic representations of the separate images. The optical storage element (1500) is contained in a sleeve (1504) which is inserted into the patient's mouth adjacent to the teeth to be imaged. A slip (1502) that absorbs the transmitted x-rays is also inserted into the sleeve (1504).

Abstract: Les gènes de réponse de la croissance régulée par transcription jouent un rôle clé dans la détermination du destin des cellules. La p53 est connue pour assurer la régulation transcriptionnelle de gènes importants en matière de régulation du potentiel de la croissance cellulaire. A l'aide d'une analyse différentielle par PCR à température ambiante, des fibroblastes d'embryons de rats contenant un allèle p53 sensible à la température, on a pu isoler plusieurs produits de transcription ainsi régulés dans des cellules contenant, de manière spécifique, la protéine p53 de type sauvage. Deux de ces gènes, SM20 et l'époxyde hydrolase (mEH) microsomique sont des gènes déjà décrits. Deux ADNc non caractérisés, les gènes CGR11 et CGR19 (CGR) régulateurs de la croissance cellulaire ont été isolés. Les séquences d'acides aminés prédits de ces nouvelles protéines contiennent des motifs connus. Les domaines du côté EF (CGR11) et un domaine annulaire (CGR19) suggèrent cette fonction. CGR11 et CGR19 semblent être les gènes de réponse primaires exprimés à 0,05 % et 0,01 % de l'ARNm total dans les cellules p53 de type sauvage. CGR11 et CGR19 ainsi que SM20 et mEH permettent d'inhiber la croissance de plusieurs lignées cellulaires.
