Patent CA-2380939-A1 (CA)
Title: Dispositifs et procedes d'interconnexion de vaisseaux chez un patient
Inventor: DEMOND JACKSON
IPC: A61B17/04
Filed: 2000-07-28
Abstract: L'invention concerne un dispositif d'implant, un procédé associé d'interconnexion rapide, sûre et la moins invasive de vaisseaux (27) humains. Le dispositif comprend un premier segment (2), un second segment (3) et une ouverture d'écoulement (4) sur le pourtour des deux segments reliés. On peut plier les premier et second segments, ce qui facilite leur introduction dans une incision effectuée dans chaque vaisseau. Dès libération, chaque segment pliable épouse par la suite les parois internes d'un vaisseau de façon à produire un contact étanche sur la surface de contact du segment introduit. L'ouverture d'écoulement présente une interconnectivité fluidique entre les vaisseaux reliés par le dispositif d'implant. Ce dernier est conçu de façon à ne pas empêcher l'écoulement à l'intérieur d'un vaisseau et hors des ouvertures dans les vaisseaux, excepté l'écoulement d'un vaisseau à un autre par l'ouverture de connexion, et à forcer les vaisseaux les uns vers les autres dans les zones entourant les ouvertures, les vaisseaux pouvant ainsi se développer ensemble de façon que l'écoulement puisse s'effectuer d'un vaisseau à l'autre.

Patent CA-2384218-A1 (CA)
Inventor: KURELEK JOHN
IPC: F15B13/06
Filed: 2000-09-06
Abstract: The two boom members and hydraulic cylinders of a knuckle boom tree harvesting machine are so arranged and proportioned that with a single control movement during reaching and retracting actions the working tool head is made to travel in an approximately horizontal path. The cylinders and control valve are so connected that during horizontal reaching action load-supporting pressurized oil from a collapsing cylinder is not required to be dumped to the reservoir in the conventional heat generating manner, but is rather shunted directly to an extending cylinder where it continues to do useful load support work. Energy waste to hydraulic oil heat and fuel consumption is significantly reduced. Although these advances have been particularly developed for disc saw felling and stroke delimbing of trees they can also be applied to other knuckle boom applications where horizontal reaching is a major function.

Abstract: A wall mountable assembly such as a wall mountable towel ring or the like includes a base part and an object support part extending from the base part. The base part is formed from a wall attachment member and a cover member which fits over the wall attachment member. The wall attachment member has an arm which extends through the cover member and which secures by a pivot connection to a cam member at the inner end of the object support part of the assembly. The object support part is swingable from a non-use to a use position relative to the base part to cause the cam member to move between a loose and a tight fitting with respect to the cover of the base part. The assembly further includes a locking member which releasably secures to the cam member and which blocks the cam member from moving away from the tight fitting holding all of the components of the assembly tightly secured to one another.

Title: Liquid fuel reservoir for fuel cells
Inventor: KINKELAAR MARK R
IPC: H01M8/04
Filed: 2002-06-28
Abstract: The present invention concerns a fuel reservoir for a liquid fuel cell particularly useful for portable electronic devices in which the fuel reservoir can deliver the liquid fuel regardless of the orientation. The fuel reservoir comprises (a) a container defining a cavity for holding the liquid fuel; (b) a wicking structure positioned within the cavity and info which at least a portion of the liquid fuel wicks and from which said liquid fuel subsequently may be discharged or delivered, such as by pumping or wicking. The wicking structure is formed from a wicking material with a free rise wick height greater than at least one half of the longest dimension of the wicking structure. Among materials with such wicking capability are foams, matted, bundled or woven fibers and nonwoven fibers. The container may have a generally flat and thin profile, formed as a pouch or envelope with substantially planar top and bottom faces of flexible film material, such that the container holding the wicking structure and tilled with the liquid fuel can be bent or shaped.

Title: Cartridge dispensing guns
Inventor: GREENHILL SILVIU
IPC: B05C17/005
Filed: 2001-02-15
Abstract: A cartridge dispensing gun comprises a pusher mechanism for incrementally displacing a dispensing piston of the cartridge, said pusher mechanism comprising a pusher rod (4) incrementally advanced by actuation of a trigger  to tilt and displace a gripper associated with the rod. The gripper is forme d by two or more gripper plates (16) mounted in parallel, and each having a passage through which the rod passes. The passage in the gripper plate is bounded at one side of the gripper plate by an arc of part-circular shape to  define a part-circular edge which grips the rod when the gripper plate is tilted upon actuation of the trigger and also by a surface which is inclined  to the axis of the passage and which contacts the surface of the rod when th e gripper plate is tilted to thereby restrict the extent to which the edge can  penetrate into the rod and cause damaging scoring of the rod.

Title: Telecommunications line parameter estimation
Inventor: CHATTELL ANDREW DAVID
IPC: H04M3/30
Filed: 2001-03-06
Abstract: A fault location system for telecommunications network including a local exchange or switch, a node such as a primary connection point and a plurality of line terminations that the customer includes probability calculation to establish the location of a fault; measuring from the exchange. Historical non-faulty reference values of capacitance are compiled for each line passing through the node providing a measure of the distance of each line.  A lowest valid capacitance value provides an estimate of the reference capacitance between the exchange and the node. Using various parameters, probability tables are compiled of historic fault values and a new fault is compared against these tables to establish the probability of it being a fault at the node or elsewhere. As a result the reference capacitance can be obtained without the need for an engineer at the node, and the likely location of a fault can be pinpointed with greater accuracy.

Abstract: A medical infusion pump is disclosed which provides for greatly improved accuracy in the delivery of medica-ments to a patient. Among the various features included in the instant invention is a pumping body which serves to deform and reform a tube so as to maintain the initial cross section thereof and thereby preserve the output accuracy of the pump. Also disclosed with regard to the pumping body is a wholly mechanical synchronization of the pump-ing body and valves associated therewith and coactive with the aforementioned synchronization a mechanical lineariza-tion of output of the pumping body per each pumping cy-cle. Additionally, several features which serve to enhance the utility of the instant invention are also included therein among which is an associated assembly operative to auto-matically load or disload a tube or IV set into or out of the pumping body. Associated with the assembly operative to automatically load or disload a tube and disclosed herein is an assembly operative to selectively open or close a slide clamp associated with the tube in such a way as to ensure that the tube is occluded such that in combination with the valves associated with the pumping body, a condition of free-flow of medicament is never realized. Additionally disclosed are sensor housings adapted to measure various quantities associated with fluid flowing through the tube wherein the housings are with associated components adapted to achieve a substantially normal orientation with respect to the sidewall of the tube and in the achieving of such normal orientation, expressing an essentially zero elastic stress gradient across the tube.
