Patent CA-2179220-A1 (CA)
Inventor: RICHARDSON ROBERT J
IPC: F16L21/08
Filed: 1996-06-17
Abstract: In restrained sealed bolted joints of fluid piping systems, including both plastic and metallic pipe, improvements have previously been made in providing adequate grip rings to keep the inserted ends of pipe in place.  When larger diameter pipes, especially larger diameter plastic pipes, were inserted into these sealed bolted joints, some difficulties were encountered.          Therefore, a compression control ring is now provided to controllably transfer and to limit the tightening force component, which moves the gasket into sealing contacts with the respective pipe sections being joined.  Also circumferentially spaced skid pads are positioned about each grip ring, assuring each respective grip ring will not prematurely commence gripping a pipe.  In addition, the gland has been improved, so any possible large assembly forces, or any large fluid pressures in the piping system will not be effective in distorting the gland.

Title: Fluid cooled and perfused tip for a catheter
Inventor: BRUCKER GREG G
IPC: A61B17/00
Filed: 1994-12-21
Abstract: The invention relates to an ablation catheter (20) which controls the temperature and reduces the coagulation of biological fluids on a tip (26) of a catheter (20); prevents the impedance rise of tissue in contact with the catheter tip (26), and maximizes the energy transfer to the tissue, thereby allowing an increase in the lesion size produced by the ablation. The ablation catheter includes a tip (26) for applying electrical energy to biological tissue. Passages (48) are positioned within the tip (26) in a variety of manners for directing a fluid flow through the tip (26) to the exterior surface of the tip (26) to control the temperature and form a protective fluid layer around the tip (26). Monitoring structure (47) is also positioned within the tip for measurement of the electrical potentials in a biological tissue. Ablation electrode structure (30) is also positioned within the tip (26) for application of ablative energy to the biological tissue. A flexible extended embodiment electrode (90) provides the capability to form deep, linear lesions along a portion of a heart wall during ablation for the treatment of particular arrhythmias.

Abstract: Procédé et dispositif améliorés permettant de surveiller l'état de dispositifs de filtrage de particules que l'on trouve dans diverses unités de filtre. L'appareil de la présente invention comporte une ou plusieurs sources lumineuses dirigées sur les unités de filtre et un ou plusieurs détecteurs correspondants qui détectent les modifications survenant dans l'intensité lumineuse provenant de la source de lumière. En cas de fuite, de la poussière est libérée dans l'atmosphère autour d'un filtre donné. Les détecteurs remarquent alors une diminution de l'intensité de lumière et signalent l'existence d'un problème. Grâce à l'utilisation de sources de lumière et de détecteurs multiples ou à l'obtention de signaux dans différents angles provenant d'une source de lumière et d'un détecteur uniques, il est possible d'identifier avec rapidité et précision des problèmes de fuite.

Patent CA-2190194-A1 (CA)
Inventor: LIU JIN HAO
IPC: C12N9/16
Filed: 1996-11-13
Abstract: A xylanase gene, denoted xynC, encoding a novel xylanase (XynC) obtained from strains of the anaerobic fungus Neocallimastix patriciarum is provided. The DNA sequence of the xynC gene is also provided. Transformation of microbial and plant hosts with the xynC gene is described. The xynC gene may be used to design probes for use in hybridization experiments to isolate xylanase genes from other anaerobic fungi. The xynC gene has been used to construct an oleosin-xynC expression construct encoding an oleosin-xylanase fusion protein which retains xylanase activity. Transgenic Brassica napus (canola), transformed with the oleosin-xynC expressionconstruct, expresses the oleosin-xylanase fusion protein which is immobilized in the oil-body membrane of the B. napus seeds. Canola meal, the protein-rich residue left after canola oil is extracted from canola plants, when derived from the transgenic B. napus of the present invention, retains substantial xylanase activity, making it an ideal animal feed supplement.

Title: Device for optical regeneration of binary signals and its use to modify the signal
Inventor: DE BOUARD DOMINIQUE
IPC: H04B10/29
Filed: 1997-06-13
Abstract: The processor receives an input signal (E) at a first stage (1) and outputs a modulated signal which has a power value between first and second power levels. Power level fluctuations due to variations in the input signal are reduced. The smoothed modulated output (B) is passed to a second stage (2) with an interferometer (7) which splits the incoming signal into auxiliary waves (AM1,AM2) and produces a signal that accentuates the input modulation by generating constructive and destructive interference outputs. The two logic output states are thus more clearly defined.
