Title: Detecteurs de gaz a electrodes multiples et leurs procedes de fabrication et d'utilisation
Inventor: WILLIAMS DAVID EDWARD
IPC: G01N27/12
Filed: 1996-12-23
Abstract: La présente invention vise un détecteur de gaz résistif constitué d'une couche sensible (11) recouvrant un réseau d'électrodes (12, 14, 16) disposées à intervalles irréguliers (22, 24). Les signaux émis par les différentes électrodes font office de résistances disséminées dans différentes parties de la couche sensible. Cette couche sensible est réalisée en une série de sous-couches successives, chacune modifiant la microstructure de la précédente. Cette variation de microstructure dans la couche sensible (11) permet de faire la distinction en un gaz réactif et un gaz qui l'est moins. L'appareil objet de la présente invention peut être utilisé à des fins domestiques pour la détection d'oxyde de carbone.

The tablets are useful in a wide variety of water treatment applications. Accordingly, the specification describes a method for controlling the growth of microorganisms in an aqueous system. Using the method, one treats an aqueous system with an ionene polymer in an amount effective to control the growth of at least one microorganism. The ionene polymer is contained in a tablet of the invention.

Patent CA-2231683-A1 (CA)
Title: Stent delivery system
Inventor: RAVENSCROFT ADRIAN C
IPC: A61F2/06
Filed: 1996-09-05
Abstract: A stent delivery system (10) with a catheter (11) has an axially extending inner core (14) and outer sheath (24), axially spaced rings (23) extending from a relatively narrow diameter portion (17) of the inner core proximate the dital end thereof. The rings engage proximal portions of a compacted stent (20) disposed within the sheath and over the core and rings. A proximal handle of the system has a first portion (25) that supports the sheath and a second portion (26) that supports the core for relative displacement of the core and the sheath. Retraction of the sheath relative to the core uncovers the stent engaged by the rings which tends to remain stationary relative to the core so that upon partial retraction of the sheath a distal end of the stent expands to its expanded form. Further retraction of the sheath deploys the stent, retracting the core returns the distal portion of the stent into the sheath.

Title: Multi-cycle loop injection for trace analysis by ion chromatography apparatus and method
Inventor: RIVIELLO JOHN M
IPC: G01N30/96
Filed: 1996-12-17
Abstract: An ion chromatographic apparatus and method for on-column preconcentration of trace ionic contaminants for quantitative trace analysis by ion chromatography. The method includes the multi-cycle, sequential steps of loading and purging of sample solution into and out of a sample injection loop (26) to cumulatively pre-concentrate a separator column (30) with a cumulative amount of sample. Each purging step includes directing pressurized liquid, at a substantially constant rate and for a predetermined period of time to the sample injection loop (26), to drive up to about 98 %  of the known volume of the sample solution from the sample injection loop (26). In turn, this flushed volume of sample solution passes through an ion exchange resin column (30) for concentration of the trace ionic contaminants in the resin.
Patent CA-2238584-A1 (CA)
Inventor: LITTLETON FRANCIS JOHN
IPC: B65H29/68
Filed: 1998-05-25
Abstract: A slow-down apparatus is disclosed using a suction box by itself to slow a sheet of paper in a paper transport apparatus, and to remove the trailing edge of a sheet from the path of the leading edge of an oncoming or following sheet to prevent lead edge damage. A set of high-speed conveyors deliver a sheet above shingled predecessor sheets being drawn by a slow-down conveyor. The shingled sheets "shutter" a suction box beneath them from affecting the delivered high-speed sheet.  As the shingled sheets uncover the suction box, the high-speed delivered sheet is affected and drawn to the low-speed conveyor.

Patent CA-2244344-A1 (CA)
Title: Control method of adaptive array and adaptive array apparatus
Inventor: HOSHUYAMA OSAMU
IPC: G10L21/0208
Filed: 1998-07-30
Abstract: An adaptive array apparatus which can follow high speed movement of an interference signal source while reducing breathing noise and maintaining high quality of an output signal. The adaptive array apparatus uses an indicative value relating to the amplitude of an output signal of a beam former and having higher sensitivity with respect to the target signal source than sensitivity with respect to another signal source, and an indicative value relating to the amplitude of an output signal of a beam former having lower sensitivity with respect to the target signal source than sensitivity with respect to another signal source, and determines a step size of an adaptive algorithm in the adaptive filter. Thus, when a constant determining a step size is set large, following speed with respect to the movement of the interference signal source accordingly becomes higher to reduce signal degradation and breathing noise.
