Filed: 1994-04-26
Abstract: A surgical instrument (10) with articulated jaw structure includes a frame (12) and two jaws (16, 18). The jaws have proximal portions (30, 36) that are mounted to each other for movement in a substantially parallel relation between a fully open position wherein the jaws are separated for receiving tissue therebetween and an approximated position whein the jaws are closer together. Preferably, the jaws are in the fully open position when the distal portion of at least one of the jaws is located in an extended position and are in the approximated position when the distal pvrtion of the extended jaw or jaws is located in a retracted position. The surgical instrument may further include a detachable knife assembly and knife actuating mechanism.

Title: Improved device for automated chemiluminescent immunoassays
Inventor: COLEMAN CAROLE LYNN
IPC: B01L3/00
Filed: 1994-04-21
Abstract: An improved device is used for performing solid-phase chemiluminescent immunoassays. The device com-prises a container having a fibrous matrix and a porous ab-sorbent material. An improvement in the device is the use of light absorbing material as the absorbent material or as a light barrier between the fibrous matrix and the absorbent material. A second improvement comprises a fibrous ma-trix of binderless fiber matrix, such as glass fiber. The invention improves the direct measurement of the chemi-luminescent signal from a solid surface by reducing back-ground signal.  The device is disposable  and is suitable for manual use or for use with an apparatus having programmed instructions. The device is designed to be employed in a variety of solid-phase diagnostic assays such as sandwich or competitive binding assays.

Abstract: Procédé de traitement d'une tumeur chez un hôte humain selon lequel on effectue la transduction in vivo des cellules tumorales avec une séquence d'acide nucléique (ADN ou ARN) codant un agent qui est capable d'assurer l'inhibition, la prévention ou la destruction du développement des cellules tumorales lors de l'expression de la séquence d'acide nucléique qui code ledit agent. Dans une forme d'exécution, on effectue ce traitement en administrant à la tumeur in vivo des cellules productrices transduites avec un vecteur retroviral comprenant un gène codant un marqueur sélectif négatif. Lorsque les cellules productrices sont administrées à la tumeur, elles génèrent des particules virales infectieuses qui infectent les cellules tumorales. Lorsqu'on administre ensuite un agent d'interaction qui interagit avec le marqueur sélectif négatif pour produire un agent qui est toxique pour les cellules tumorales, les cellules tumorales transduites sont détruites. Dans une forme d'exécution préférée, on utilise ce procédé pour traiter les tumeurs cérébrales chez l'homme.

Inventor: LEBLANC MICHEL
IPC: H04B10/071
Filed: 1996-10-04
Abstract: An optical time domain reflectometer suitable for determining its front panel insertion loss comprises a four-port coupler having first and second ports connected to a light source and an optical detector, respectively, and third and fourth ports connected to a front panel output connector and a reference reflector, respectively. In use, a fiber-under-test is connected to the front panel output connector. The coupler splits light from the light source between the front panel output connector and the reference reflector and couples light returning from the front panel output connector and roflector to the detector. The optical path between the front panel output connector and the coupler is longer than the optical path between the reference reflector and the coupler by such a distance that a Fresnel reflection pulse from the reference reflector, produced by a pulse emitted by the light source, will be received by the detector before a corresponding reflection pulse returned from the front panel output connector. In order to ensure that the two reflection pulses can be distinguished from each other, the difference between the two optical paths is greater than a distance equal to an event dead zone for the particular width of pulse supplied by said light source. The reference reflector comprises an end portion of a length of optical fiber, preferably encapsulated with a material having a refractive index different from that of the length of optical fiber. The OTDR facilitates miniaturization because it avoids the use of an internal length of reference fiber,

Abstract: On produit des biscyanoacrylates en solution par mise en réaction d'acide 2-cyanoacrylique ou de ses esters d'alkyle avec des diols en présence d'acides sulfoniques comme catalyseurs. On traite le mélange de réaction en remplaçant le solvant aromatique par un solvant aliphatique, puis le mélange de réaction est soumis deux fois à une cristallisation fractionnée. Les biscyanoacrylates ainsi obtenus se caractérisent par leur haut degré de pureté. Ils sont par conséquent utiles pour produire des adhésifs cyanoacryliques stables au stockage. Leur adjonction augmente la résistance thermique de l'adhésif, ce qui est particulièrement important dans le cas de composants électriques et électroniques.
Patent CA-2192893-A1 (CA)
Inventor: WOERNER KLAUS D
IPC: B65G60/00
Filed: 1996-12-13
Abstract: The system is for loading or unloading parts onto or from trays. The same system may be used for either function. A stack of trays loaded on a cart is wheeled into a first cart docking bay. A second cart is positioned in a second cart docking bay beside the first bay, to receive processed trays. A first tray elevator lifts the first cart and trays, or just the trays, to align the uppermost tray with a tray singulator and clamping mechanism. The tray is singulated, i.e. first supported at a lip by retractable opposing support rails and then separated from the stack byoperation of the elevator to lower the tray stack, and is then clamped in a precise position. It is subsequently unclamped and shuttled laterally into alignment above the second cart, onto identical retractable support rails, where it is similarly clamped in a precise position. The next tray is then raised by the first elevator and singulated and clamped in position, so that there are then two precisely positioned trays, one above each cart and tray stack. A robot loads or unloads parts onto or from trays at either location, transferring the parts from or to a target location, such as a pallet on a conveyor passing through the system, for example. This loading or unloading takes place primarily at the shuttled tray. When the shuttled tray is completely filled or emptied as the case may be, it is unclamped, the second elevator is lifted toprovide support for the tray, the singulator mechanism is opened to release the tray, and the tray stack is lowered, thus clearing the way for the next tray to be shuttled across. While the filled or emptied tray is being lowered, the robot can transfer parts to or from the tray above the first stack, thereby minimizing delays in the cycle.
