Title: Atm dynamic connection bandwidth control
Inventor: TOOP DARREN FREDERICK
IPC: H04L12/56
Filed: 1998-06-12
Abstract: An apparatus for changing bandwidth loading by a bandwidth change amount in a communications interface having elastic and non-elastic call connections where the elastic and non-elastic call connections have associated current cell rates and equivalent cell rates respectively.        The apparatus includes a processor programmed to determine whether the bandwidth change amount is negative or positive. When the bandwidth change amount is negative the processor reduces the current cell rate of each elastic connection and releases at least some non-elastic connections such that the current cell rate of each elastic connection is reduced and the non-elastic connections are released until the total of the current cell rates of the elastic connections and the equivalent cell rates of the non-elastic connections have been reduced by at least the bandwidth change amount. When the bandwidth change amount is positive, the processor increase the current cell rate of each elastic connection and restores non-elastic connections.

Title: Singleshot anastomosis instrument with detachable loading unit and method
Inventor: HINCHLIFFE PETER W J
IPC: A61B17/128
Filed: 1998-06-11
Abstract: There is disclosed a surgical instrument and loading unit for performing an anastomosis of first and second blood vessels. The surgical instrument includes a handle assembly and a body portion extending distally from the handle assembly. The detachable loading unit includes an anvil releasably engagable with a distal end of the body portion and having a plurality of fasteners disposed in channels about the circumference of a distal end of the anvil. A pusher is slidably mounted over the anvil such that distal movement of the pusher in response to actuation of the handle assembly cams the fasteners between the anvil and a distal end of the pusher to simultaneously crimp the fasteners about tissue. A method of performing an anastomosis is also disclosed and includes positioning a first vessel in the loading unit and partially inserting the first vessel through an opening in a second vessel. The surgical instrument is subsequently attached to the loading unit and the handle assembly is actuated to crimp fasteners about the first and second vessels to form an anastomosis.
Patent CA-2241522-A1 (CA)
Inventor: RAPPAPORT MARK
IPC: B62K3/00
Filed: 1998-06-24
Abstract: A dual-footboard scooter in a tricycle format, the front wheel of the scooter being coupled to a steering post passing through a steering column to join a steering handle provided with a hand brake operatively coupled to the front wheel. A pair of parallel footboards are attached at their front ends to a bifurcated frame extending rearwardly from the steering column. Secured to the underside of each footboard is a rear end wheel behind which is a skid brake adapted to engage the ground only when the footboard is upwardly tilted. In operating the scooter, the rider grasps the steering handle, one foot then resting on either one of the footboards, the other foot extending through the space between the footboards to make pushing contact with the ground to propel the scooter forward. Should the scooter jump in the course of travel and in doing so raise the front wheel above ground and cause the footboards to become upwardly inclined, the scooter then seeks to swing backward about the rear wheels and thereby endanger the rider. The action is avoided by the rear skid brakes which then engage the ground to cause the scooter to swing forward to return the front wheel to the ground.

Abstract: An apparatus for isolating the abdominal muscles and effectively loading them during exercise is disclosed. The device supports the user's body in a position which allows for trunk flexion; however, it forces the user's knee flexor and hip extensor muscles to contract, relaxing the hip flexor muscle, and isolating the abdominal muscles. Consequently, the only muscles exercised during the trunk flexion are the abdominal muscles.

IPC: F02F7/00
Filed: 1997-03-06
Abstract: On fabrique un moulage de piston tridimensionnel à partir d'un mélange de filaments d'étoupe en carbone coupés de longueur variable, qui sont préimprégnés avec des résines et/ou des poix organiques carbonées et moulés par des procédés de moulage traditionnels sous la forme de structures quasi-réticulaires, de façon à constituer des pièces composites à matrices organiques renforcées par des fibres de carbone. Des renforcements continus, sous la forme de bandes ou de pièces de toile composites carbone-carbone, peuvent également être déposés dans le moule avant ou après le chargement du moule avec le mélange de fibres coupées, pour améliorer la résistance dans les zones de la couronne (21) et du maneton (23). Ces pièces composites moulées à matrices organiques renforcées par des fibres sont ensuite pyrolysées dans une atmosphère inerte, pour assurer la conversion des matériaux à matrices organiques en carbone. Ces pièces pyrolysées sont ensuite densifiées par réimprégnation avec des résines ou des poix, qui sont ensuite carbonisées. La densification est également réalisée par infiltration directe avec du carbone par des procédés de dépôt en phase vapeur. Une fois que la densité désirée a été atteinte, ces pièces moulées de pistons sont usinées aux dimensions finales, et des rainures de segments de pistons sont ajoutées. Pour empêcher l'oxydation et/ou pour réaliser l'étanchéité des pistons à la surface ou dans le voisinage de la surface, le piston en fibres coupées (20) est recouvert d'agents d'étanchéité céramiques et/ou métalliques et/ou il est recouvert d'un catalyseur.

Title: Gas turbine first-stage stator blade sealing structure
Inventor: SHIBATA HIROKI
IPC: F01D11/00
Filed: 1998-06-04
Abstract: A sealing structure for a first stage stator blade of a gas turbine (1), capable of preventing the leakage of sealing air from the interior of the blade even when the stator blade inclines due to thermal stress occurring therein, comprising an arcuately formed rear flange (12) of a first stage stator blade (31), a linear rib (10) provided on the rear flange, and a stator blade support ring (13) in contact with the rib to form a sealing surface.  When the rear flange (12) and the stator blade support ring (13) are inclined relatively to each other as shown by 13a, 13b, an upper or lower end of the horizontal rib (10) and a surface of the circular stator blade support ring (13) are brought into linear contact with each other, so that there arises no clearance that prevents the leakage of the sealing air. When a stator blade support ring (13) of a conventional gas turbine is inclined, an arcuate clearance occurs between the support ring and a rear flange (12) since no horizontal rib (10) is provided, so that the sealing air leaks from the interior of the gas turbine into a gas passage. The present invention can prevent this inconvenience.

Title: Method and apparatus for joining veneer pieces with lap joint having square cut edges and reduced thickness
Inventor: KNOKEY EUGENE R
IPC: B27M1/02
Filed: 1999-05-05
Abstract: A method and apparatus for joining two pieces of wood veneer with square cut edges by a lap joint with a pre-determined thickness not greater than the thickness of a single piece of veneer. The lap joint is formed in a press which may have heated plates for pressing the overlapping portions of the veneer pieces together. The press is provided with adjustable stops for limiting the spacing between the platens in the final pressed position to provide the lap joint with the pre-determined thickness. The lap joint is bonded by glue provided on the surface of at least one of the overlapping portions of the two veneer pieces. The lap joint is heated to an elevated temperature above the lignin softening temperature of the veneer during pressing to enable thermoplastic flow of the wood veneer which produces a lap joint of greater strength. The two platens are formed with anvil surfaces including flat middle surfaces which are parallel, and side surfaces on opposite sides of each middle surface which slope away from each other and which are joined to the middle surface by curved transition portions to avoid cutting the veneer and produce a stronger lap joint.
