Abstract: Cette invention concerne un instrument intégré permettant une analyse électrophorétique performante d'échantillons de biopolymères. Cet instrument comprend un module électrophorétique à haute tension spécialisé dans lequel des couloirs de migration sont formés entre une plaque inférieure (446) et une pluralité de rainures gravées dans une plaque supérieure (438), ce module permettant la séparation simultanée de 80 échantillons distincts ou plus. En contact thermique avec la plaque inférieure (446), on trouve un module de régulation thermique incorporant une pluralité de dispositifs de transfert thermique à effet Peltier qui assurent une régulation de la température et des gradients à l'intérieur du milieu électrophorétique. Des fragments sont détectés par un spectrographe formant des images de l'émission, qui effectue simultanément une mise au point spatiale et une résolution spectrale de la région de détection de tous les couloirs de migration. Ledit spectrographe comporte un élément de dispersion de l'émission ainsi qu'une matrice à couplage de charges pour détecter les signaux. L'analyse des signaux consiste à filtrer les bruits, à comparer les signaux dans un espace d'arrangement avec des prototypes de signaux et à choisir le meilleur prototype. On peut éventuellement effectuer un post-traitement au moyen d'un algorithme d'annelage simulé par la méthode de Monte-Carlo afin d'améliorer les résultats. On peut aussi éventuellement intégrer un ensemble de micro-réacteurs audit instrument pour permettre la production de fragments de réactions de séquençage directement à partir d'échantillons d'ADN bruts.

Patent CA-2239029-A1 (CA)
Inventor: BETT THOMAS ARTHUR
IPC: B29C65/74
Filed: 1996-12-06
Abstract: An ultrasonic method and system for intermittently changing a condition of a workpiece is disclosed. The ultrasonic system includes an ultrasonic horn and a rotating anvil roll positioned to form a close relationship with each other comprising a nip. One of the ultrasonic horn and the rotating anvil roll includes an outer radial surface having a first length (40) having a first amount of surface area per unit length of the respective outer radial surface, and a second length (42) having a lesser amount of surface area per unit length of the respective outer radial surface. When ultrasonic energy is applied to the ultrasonic horn, the second length changes a condition of the workpiece when applied in the nip, but the first length does not change that condition. The change in condition occurs because the decrease in surface area along the second length (42) increases the ultrasonic energy per unit area, as applied in the nip, to at least the threshold amount necessary to change the condition. Changes in condition of the workpiece include bonding together two or more layers of material, cutting one or more layers of material, or the like. Various patterns and designs can be provided at the working outer radial surface of the ultrasonic horn and/or the rotating anvil roll, for processing the workpiece. In one embodiment, a first discrete length of a pattern repeats multiple times in a single rotation of the anvil roll or ultrasonic horn with respective second discrete lengths therebetween. In another embodiment, the anvil roll or ultrasonic horn includes opposing side portions upon either side of a central region wherein the central region includes the pattern and thus the reduced surface area. The pattern may include lands extending from an underlying base surface to a radius, at the respective outer radial surface, in common with the radius at the first length of the outer radial surface. By having the lands in the outer radial surface of the second length at the same radius as the outer radial surface in the first length, the respective ultrasonic horn or rotating anvil roll comprises a constant radius at its outer radial surface so the ultrasonic system is substantially free from changes in tension on the workpiece caused by surface characteristics of either the ultrasonic horn or the rotating anvil roll.

Abstract: A mixing nozzle for mixing a primary and a secondary fluid, has an inlet for primary fluid, a fluid mixing zone located downstream of the inlet, a plurality of secondary fluid inlets in spaced, convergent relation with the axis of flow of the primary inlet, wherein the secondary inlets are inclined in converging relation towards the primary inlet flow axis, at an angle of less than 90 degrees therefrom.  In one embodiment a portion of the nozzle is selectively movable in flow controlling relation with the secondary nozzles, in use to enable effective control of the proportion of secondary fluid admitted to the fluid mixing zone in response to a flow of primary fluid thereto.  In a gas burning heating torch embodiment a portion of the nozzle structure is movable, to selectively control the admission of the secondary fluid, air, to the mixing chamber. In one embodiment the air intake nozzles are inclined at about 45 degrees to the axis of the gas inlet. The movable nozzle portion is connected by screw threads to the body of the torch, such that relative rotation thereof effects the desired adjustment in the gas to air ratio.  When used as a blowtorch the nozzle runs cool to the touch, and can be readily handled during use.  The torch is enable for ready use with propane or with acetylene, by the provision of a replaceable regulating throttle piece at the gas inlet end.  This also can be used to change the range of heat output of the torch.
