Inventor: CAGE DONALD R
IPC: G01L9/00
Filed: 1995-04-18
Abstract: La présente invention concerne plusieurs géométries et circuits électroniques de débitmètres de type Coriolis à mode radial qui peuvent être rendus sensibles à la pression ou aux variations de densité. Dans un mode de réalisation, le débitmètre comprend (A) un conduit d'écoulement (1) destiné à contenir un fluide doté d'une caractéristique physique, ledit fluide (21) étant adapté pour s'écouler dans le conduit à une vitesse inconnue, (B) un circuit d'actionnement (16, 17) destiné à créer une vibration dans le conduit (1) de fluide, le fluide (21) modifiant la vibration en fonction de sa caractéristique physique et de la vitesse d'écoulement, (C) un circuit de détection (10-15) destiné à mesurer la vibration modifiée au niveau d'un point de travail (38, 55) et à produire un signal représentant un débit-masse non compensé (M1) du fluide et (D) un circuit de calcul destiné à calculer un débit-masse (M2) compensé du fluide proportionnel de 1/.OMEGA.1?n¿ à la vitesse non compensée, .OMEGA.1 étant une fréquence naturelle entraînée du conduit de fluide et n un nombre choisi en tant que fonction du point de travail, la vitesse compensée étant ainsi débarrassée des effets de la caractéristique physique. Un algorithme mathématique unique permet en outre d'obtenir une variété bien plus grande de géométries de conception tout en maintenant l'insensibilité à la pression ou à la densité sans avoir à mesurer ou à compenser l'une ou l'autre. Un procédé qui permet la mesure et la compensation précises de la pression ainsi que de la densité est également décrit.

Abstract: A  low  rate  telemetry  transmission  method  for transmission of digital information between a transmission side   and   a   receiving   side,  comprising:  transmitting digital information on a channel at a predetermined bit rate; selecting a pre-determined frame of digital information in the channel; selecting one of at least two digital information elements desired to be transmitted with and in addition to those in the frame; obtaining a key,  known at transmission and  receiving  sides  defined  by  a  sequence  of  digital information which after predetermined processing substan-tially uniquely identifies the selected digital information element; performing as part of said predetermined processing a  first  reversible  mathematical manipulation  of  the  key and the digital information element to produce a first output; performing a second reversible mathematical manipulation of the first output and the digital information in the frame, to obtain  an  encoded  digital  information  sequence,  and transmitting  that  encoded  sequence;  and,  receiving  and decoding the transmitted encoded sequence by reversing the mathematical manipulation to obtain the frame of digital information in the channel and the key, and identifying the selected element from the key.
Patent CA-2188455-A1 (CA)
Inventor: OKUMURA YUKIHIKO
IPC: H04J13/00
Filed: 1996-02-23
Abstract: L'invention a pour objet un procédé de transmission à vitesse variable selon lequel la vitesse de transmission des données peut être modifiée librement. Du côté émission, une séquence de données de transmission est transmise à un circuit (105) de codage de détection d'erreur et une mémoire d'images (103). La mémoire d'images (103) contient des données à longueur variable qui sont transmises sous forme d'images. Le circuit de codage de détection d'erreurs (105) calcule les codes de détection d'erreurs (par exemple, des codes CRC pour chaque image des données de transmission). Un circuit multiplexeur (104) ajoute les codes de détection d'erreurs calculés à l'image située juste avant les données de transmission, à savoir, à la tête de l'image, et émet successivement des séquences de données, image par image. Du côté réception, les codes de détection d'erreurs des données dans l'image transmise sont calculées de la même manière que du côté émission et les codes de détection d'erreurs calculés sont comparés aux codes de détection d'erreur à la tête de l'image. La position dans laquelle les deux codes de détection d'erreur correspondent est désignée comme étant le dernier bit de données dans l'image. Par conséquent, les données à longueur variable peuvent être transmises sans que le côté récepteur soit informé sur la longueur des données de chaque image. Cela est équivalent au cas où la vitesse de transmission peut être librement modifiée.

Title: Slip yoke assembly for vehicle driveshaft
Inventor: SMITH JOHNNY N
IPC: F16C3/03
Filed: 1996-12-20
Abstract: A slip yoke assembly for a vehicle drive train assembly includes a yoke shaft having a shaft portion with a plurality of external splines formed thereon. A hollow transition member having a plurality of internal splines is connected to the yoke shaft for rotational driving movement, yet is permitted to move axially relative thereto. A hollow weld ring is secured to the yoke shaft for rotational movement therewith. The weld ring extends co-axially about the splined connection between the transition member and the shaft portion of the yoke shaft and provides an exterior surface to which one or more balance weights may be secured. The weld ring also provides an annular space to retain a quantity of lubricant for the splined connection. A flexible convoluted boot is provided to seal the splined connection between the transition member and the shaft portion of the yoke shaft. A first end of the boot is secured to the weld ring, while a second end of the boot is secured to the transition member. The boot prevents contaminants from entering into the splined connection between the transition member and the shaft portion of the yoke shaft. A sleeve cup is also provided to seal the splined connection between the transition member and the shaft portion of the yoke shaft. The sleeve cup includes a circular body portion having a relatively short, axially extending flange portion. The circular body portion of the sleeve cup extends over the open end of the transition member to prevent contaminants from entering into the splined connection between the transition member and the shaft portion of the yoke shaft through the interior of the driveshaft section. The flange portion of the sleeve cup is frictionally engaged between the inner cylindrical surface of the driveshaft section and the outer cylindrical surface of the transition member to retain it in position during use.

Title: Waxless composition for cleaning and polishing acrylic and glass surfaces
Inventor: DAGENAIS JEAN
IPC: C09G1/18
Filed: 1997-02-28
Abstract: The invention relates to a waxless composition for cleaning and polishing acrylic and glass surfaces, which  consists  of  a  water-in-oil  emulsion  comprising water,  naphtha mineral  spirits,  an  abrasive,  an anti-static   agent,   a   thickening   agent,   dimethoxysilyl-dimethylamino-ethylaminopropyl  siloxane,  an  aminofunctional siloxane   capable   of   reacting   with   the dimethoxysilyl-dimethylamino-ethylaminopropyl siloxane to form a cross-linked siloxane film and at least one emulsifying agent having hydrophilic functional groups.  The dimethoxysilyl-dimethylamino-ethylaminopropyl     siloxane and aminofunctional siloxane are sufficiently diluted to prevent reaction with one another in the emulsion so that when the composition is applied to an acrylic or glass surface  and  the  water  evaporates,  the  aminofunctional siloxane  reacts  with  the  dimethoxysilyl-dimethylamino-ethylaminopropyl  siloxane  to  form  the  cross-linked siloxane  film.  Such  a  film  imparts  to  the  surface  a uniform high gloss and water repellency, and efficiently protects  the  surface  against wear  and tear  caused by dust, cigarette smoke and fingerprints.

Filed: 1995-10-27
Abstract: A method and system are provided for effecting interactive, three-dimensional renderings of selected body organs for purposes of medical observation and diagnosis. A series of CT images of the selected body organs are acquired. The series of CT images is stacked to form a three-dimensional volume file. To facilitate interactive three-dimensional rendering, the three-dimensional volume file may be subjected to an optional dataset reduction procedure to reduce pixel resolution and/or to divide the three-dimensional volume file into selected subvolumes. From a selected volume or subvolume, the image of a selected body organ is segmented of isolated. A wireframe model of the segmented organ image is then generated to enable interactive, three-dimensional rendering of the selected organ.
