Patent CA-2201464-A1 (CA)
Inventor: LOLAGNE FRITZ
IPC: A61B17/28
Filed: 1997-04-01
Abstract: A forceps having a closed loop defined by the ends of beveled grasping tips attached to a pair of jaws of locking forceps in a closed position,  a series of mating serrations on the jaws ending proximate the loop,  and a  second  embodiment  thereof  having  an hourglass shape when viewed in profile.  The forceps reduces slippage of tubular or stranded tissue by a raised bevelled ridge on the closed loop facing inward towards the aperture. The oval-shaped and hourglass profiled aperture defined by the closed loop of the second embodiment is shaped and sized to permit a surgeon to firmly grasp the vagus nerve, and the first embodiment is sized to closely grasp the vas deferens, to  allow  elevation  of  either up  and out  of  the incision area, in order to facilitate the remaining procedure.  The preferred aperture opening as defined by the larger loop of the second embodiment has a 3 mm transverse inner diameter and 4 mm longitudinal inner diameter.   The hourglass profile allows the vagus nerve to rest in a transverse groove of the tip, defining  the  constriction  found  in  the  hourglass profile.   The mating serrations, which form a line following the lengthwise extension of the instrument, provide a continuous,  firmly closed line behind the loop and define the longitudinal axis of the forceps. The arms of the second embodiment are approximately 11 centimeters long, thereby providing additional reach necessary  in  surgical  interventions  in  the  lower esophagus and stomach where the vagus is present.
Patent CA-2204058-A1 (CA)
Title: System and method for automated network reconfiguration
Inventor: NUSBAUM KURT
IPC: H04M7/12
Filed: 1997-04-30
Abstract: A method is disclosed for providing an enhanced level of security for sensitive or proprietary information associated with information transactions in a public network, such as the Internet. In carrying out that method, an on-line information transaction is bifurcated between a generalized information access portion of such a transaction and an exchange of sensitive user information.  With such a bifurcation, the generalized information access portion of the transaction, which generally would constitute the more substantial (in terms of network resources) portion of the transaction, would be handled via a non-secure network, usually a public network such as the Internet. The portion of the transaction involving sensitive user information, on the other hand, would be handled by a separate secure connection, such as a private network, or intranetwork. An important characteristic of this bifurcation arrangement is the provision of a means for automated reconfiguration of a user terminal as between accessing the generalized information via the non-secure network and access to the secure communications network for the exchange of sensitive user information. Such an automated reconfiguration will be carried out without the necessity for any action on the part of the user, and indeed will be largely invisible to the user.

Patent CA-2231370-A1 (CA)
Title: A mobile telecommunicating device and method of operation
Inventor: WILLIAMS ROLAND E
IPC: H04W48/18
Filed: 1996-08-30
Abstract: A remote unit (10) has the ability to switch (13) automatically from a public network to a non-public network comprising private and residential base stations. In the preferred embodiment, the public network is characterized by cells with each cell having a unique identification signal. Initially, a first switchover from a public network to a non-public network requires the user to manually cause the switchover. The remote unit stores (31) the first identification signal transmitted by the base station from which the remote unit traversed into the region covered by the non-public base station. In addition, the remote unit stores (31) the identification signal associated with a cell of the public network previous to the current cell if the switchover occurred less than two (2) minutes from the exit of the previous cell. In this manner, the remote unit can adaptively learn as it traverses other possible paths from other cells into the region covered by the nonpublic base station.

Patent CA-2233395-A1 (CA)
Title: Dynamic bandwidth management and rerouting
Inventor: SO TRICCI
IPC: H04L12/911
Filed: 1998-03-26
Abstract: A communications network performs a variety of maintenance actions. One of those actions is rerouting of a connection path. A feature called "dynamic resource management option" allows the network or the called party of an active connection to initiate a resource change procedure when needs arises. The resource change can also be achieved by rerouting the existing path of the active connection. However a maintenance action taken in one network domain is only effected within the same domain, because a different domain may have different maintenance procedures.      Telecommunication connections often span more than one domain and a request for resource adjustment must be considered differently for a proper maintenance action. A resource change indication message includes a flag to indicate the message originated within or outside the domain. By observing the flag, it is possible to decide on a proper maintenance procedure.

Title: Method and device for purifying exhaust gas of engine
Inventor: TANAKA HIROSHI
IPC: F01N13/02
Filed: 1996-10-31
Abstract: An exhaust manifold (7) of an en-gine (I) is connected to a three way (TW) catalyst (8a), and the TW cata-lyst (8a) is connected to an NHs ad-sorbing and oxidizing (NH3-AO) cata-lyst (10a). The engine (I) performs the lean and the rich engine operations al-ternately and repeatedly. When the en-gine (1) performs the rich operation and thereby the exhaust gas air-fuel ratio of the exhaust gas flowing into the TW catalyst (8a) is made rich, NO x  in the inflowing exhaust gas is converted to NHs in the TW catalyst (8a). The NH3 is then adsorbed in the NH3-AO cata-lyst (10a). Next, when the engine (1) performs the lean operation and thereby the exhaust gas air-fuel ratio of the ex-haust gas flowing into the TW cata-lyst (8a) is made lean, NO x in the ex-hausted gas passes through the TW cat-alyst (8a), and flows into the NHs-AO catalyst (10a). At this time, NH3 ad-sorbed in the catalyst (10a) is desorbed therefrom, and reduces the inflowing NO x.

IPC: D21D5/20
Filed: 1996-03-02
Abstract: An apparatus is disclosed for processing fibre suspensions, in particular extracted from used paper, which contain particles which are also suspended and which need to be separated from the useful fibres in the suspension and whose volume weight is different from the volume weight of the fibers. The apparatus has a drum-shaped outer casing (10) which in the area of its inflow end is provided with an inlet (50) for the fibre suspension to be processed and holds a body (26) which is rotationally symmetrical around the axis of the casing. At its outflow end, the outer casing (10) has a stationary discharge pipe (60) (light-weight impurities outlet) which is concentric to the axis of the casing and receives a first fraction of the suspension (light-weight impurities) with specific light-weight particles to be separated from the suspension, as well as a useful material outlet (74) for a second fraction of the suspension which contains useful fibres (useful material). A rotary drive generates a rotary flow component around the axis (18) of the casing in the ring-shaped space between the outer casing (10) and the rotationally symmetrical body (26). In order to discharge heavy impurities, but above all to reduce costs due to wear, this apparatus has a stationary outer casing and useful material outlet and the rotationally symmetrical body is designed as a rotationally symmetrical partition wall (56) around the axis of the casing and which forms together with the circumferential wall of the outer casing a ringshaped outer chamber (58) whose face towards the rotor is open and whose opposite face is closed. At an axial distance from its open face, the ringshaped outer chamber (58) has an outlet (66) for a third fraction of the suspension which contains specific heavy particles (heavy impurities fraction) to be separated. The outlet (74) of useful materials communicates with the outflow end of an inner ring-shaped chamber (70) located between the partition wall and the light impurities discharge pipe.
