Patent CA-2196717-C (CA)
Title: Air eliminator
Inventor: RUSCHKE RICKY R
IPC: A61M5/38
Filed: 1997-02-04
Granted: 1999-12-21
Abstract: A air elimination device for removing air or gas bubbles from aqueous liquids flowing through an intravenous delivery system.  The device comprises a housing having an interior chamber, an inlet passage, an outlet passage, and one or more vent openings.  The inlet passage delivers the liquid into the interior chamber.          The outlet passage delivers the liquid from the interior chamber.  A hydrophobic membrane is attached to the housing and positioned over the vent openings.  The hydrophobic membrane allows gas bubbles in the aqueous liquid that enter the interior chamber of the housing to pass through the vent openings while preventing the liquid from passing through the vent openings.  The outlet passage comprises a stem which extends inwardly into the interior chamber and terminates in an interior end.  The vent openings are shaped and located in the housing such that at least a portion of a vent opening will be positioned at a higher elevation than that of the interior end of the stem irrespective of the orientation of the housing.
Patent CA-2205820-C (CA)
Title: Optic position sensor
Inventor: DRENTH RONALD R
IPC: G01S17/87
Filed: 1997-05-22
Granted: 2002-11-26
Abstract: The present invention involves an apparatus and a method for optically detecting and determining the angular position of a target.  The apparatus comprises a pair of optic sensors arranged so that at least a portion of their sensing areas overlap.  Their overlapping areas define the total sensing, or active sensing, area for the apparatus.  Each of the optic sensors in the apparatus senses light, or other optically sensible transmission, either projected or reflected from a target positioned within the total sensing area and produces a signal relative to the amount of light sensed.  The signals are then interpreted to determine the angular position of the target based on the relative signals from the optic sensors.  The method of the present invention determines the angular position of a target within an area, defined by the overlapping sensing areas of a pair of optic sensors, by interpreting the relative signal intensities from the pair of optic sensors.  Once the angular position is determined, the distance of the target from a line either perpendicular to or parallel to the center line of the sensor array can be calculated if the other quantity is known.

Granted: 2002-01-08
Abstract: A detachable anvil assembly for use with an apparatus for performing circular anastomosis of tubular organs includes an elongated anvil rod having proximal and distal end portions and an anvil head mounted to the distal end portion of the anvil rod.  The distal end portion is pivotally mounted and is adapted to pivot approximately plus or minus ninety degrees relative to a longitudinal axis defined by the rod.  An elongated delivery member detachably receives the anvil assembly and facilitates delivery of the anvil assembly to the operative site.  The pivoting feature of the distal end reduces the transverse profile of the assembly which consequently facilitates introduction and advancement of the anvil assembly within the tubular organ.

Title: Reseaux de telecommunications
Inventor: HOY MICHAEL DAVEY
IPC: H04M3/36
Filed: 1997-02-27
Granted: 2002-06-25
Abstract: La présente invention concerne l'émission d'une indication de saturation à destination de la plate-forme NTCC émettrice s'il y a dépassement d'une limite de volume et/ou de débit au niveau d'un itinéraire d'acheminement particulier ou d'un commutateur dans le cas d'un réseau de télécommunications d'un type traitant, en plus du trafic téléphonique normal, les appels autres qu'à temps critique ou "NTCC" (pour "Non-Time-Critical Calls"). Les plates-formes émettrices (9, 10, 11) déterminent une cadence d'émission en se basant sur un taux de rejet des appels ou "GR" (pour "Gapping Rate"). A réception d'un signal de saturation, les plates-formes calculent un intervalle entre appels ou "ICD "(pour "Inter Call Delay") en prenant pour base un nombre aléatoire multiplié par un facteur de pondération évalué à partir de la valeur courante de GR. Ce procédé instaure une période pendant laquelle il n'y a aucune tentative d'appel, et après laquelle un rapport commun permet de corriger GR de façon à conférer une valeur plus élevée à GR, ce qui fait que la cadence d'émission (ou la cadence selon laquelle se fait l'offre des appels) à destination de l'itinéraire d'acheminement est moins onéreuse. Les échecs des appels qui s'ensuivent provoquent un rapide accroissement de la valeur de GR, ce qui entraîne, non seulement une durée plus importante des ICD (de façon à permettre le rétablissement de l'itinéraire d'acheminement ou du commutateur qui a subi la saturation), mais aussi une charge de trafic moins importante après le rétablissement. En outre, la randomisation des ICD d'une plate-forme à l'autre fait que les différentes plates-formes émettrices reprennent l'émission à des instants différents.

Title: Process for producing mercaptoalkanesulfonates and phosphonates and derivatives thereof
Inventor: HARIDAS KOCHAT
IPC: C07C319/16
Filed: 1997-09-23
Granted: 2005-06-07
Abstract: A two step single-pot process for producing dimesna (NaSO3-(CH2)2-S-S-(CH2)2-SO3Na) begins by reacting an .omega.-alkenesulfonate with a sulfide such as NaSH to yield mesna (HS-(CH2)2-SO3Na). (This can be isolated or converted to a C1-4 thioalkyl ether thereof by reaction with sodium alkoxide and an alkyl halide). In the second step, mesna is oxidised in situ with oxygen gas to yield dimesna. Higher alkane homologues and analogous phosphonates are prepared similarly. When preparing a phosphonate analogue a haloalkanephosphonate is an alternative starting compound. The C1-4 alkylene chain analogues of these compounds can be prepared similarly.

Abstract: In a catalytic sensor, a bead 1 is located within a can 2 having an aperture 3 in its front surface. The bead 1 is surrounded by thermally insulating material 9, such as glass fibre and a filter material 10 is arranged between the bead 1 and the aperture 3 in the can 2. This acts to remove H2S or other inhibiting gases before they reach the bead 1 and impair its performance. The thermally insulating material allows the filter material to be included whilst still permitting the bead 1 to be operated at a high temperature.
