Patent CA-2136279-C (CA)
Inventor: ADAMS SIEGBERT
IPC: F16K1/226
Filed: 1994-11-21
Granted: 1999-04-13
Abstract: Disclosed is a disc valve with a laminated seal ring secured to the housing which forms a leakproof seal with a seating surface on the valve disc.  The seal ring is made of two or more metal laminates, the outer peripheral edges of which are cold welded together, by WIG welding or laser welding, for example, to prevent any leakage of fluid past the opposing, abutting surfaces of the laminations.  A bolt-tightened pressure ring presses the laminated seal ring in an axial direction against an axially oriented support face of the housing. An axially open groove in support face is covered by the proximate seal ring lamination and is filled with a graphite gasket to prevent leakage behind the seal ring.  Alternatively, the laminated seal ring can be mounted on the disc and the cooperating valve seat is formed on the housing.

Title: Electrophysiological sensing, for mapping, pacing and ablating
Inventor: GOLDREYER BRUCE N
IPC: A61B5/308
Filed: 1994-01-05
Granted: 2008-09-30
Abstract: Mapping of electrophysiologic activation within the human heart is achieved for areas within the myocardium by utilizing a catheter (32) having at least one pair of orthogonal sensors (34-46) disposed on the catheter (32). Orthogonal sensors (34-46), which ace comprised of electrodes generally disposed circumferentially on the catheter (32) at given longitudinal points spaced 1-5 millimeters along the catheter (32), receive signals which are differenced within a differential amplifier (50) to produce a signal indicative only of the localized biopotential heart activity at a predetermined point in the myocardium. The orthogonal sensors (34-46) are disposed adjacent to the stimulating tip (58) of the catheter (32) to allow sensing of the localized cardiac activity adjacent to or in contact with the tip during the pacing procedure or during the delivery of energy during ablation. Sensing of the localized activity occurs simultaneously with pacing or ablation so that electrocardiograms of the stimulated or ablated tissue can be recorded.

Title: Method and apparatus for fluxing and soldering terminals on a printed circuit board
Inventor: PETERSON JOHN P
IPC: B23K1/20
Filed: 1995-08-30
Granted: 2002-11-19
Abstract: Fluxing and soldering terminals on a printed circuit board by an in-line process in which flux concentration is determined at specific locations laterally of the passline.  At each of the positions infrared light is passed through a wall of flux which is being directed at the board.  The infrared light becomes partly absorbed by materials in the flux and the unabsorbed light which passes through the wall of flux is used to generate signals corresponding to the different wavelengths of unabsorbed light at each of the locations.  This enables a determination to be made of the flux concentration at each location.  The signals are preferably used to effect a change in the flow rate of flux at any specific location so as to control the amount of flux deposited upon the board. Particularly useful for "no-clean" flux applications.

Abstract: The amount of elemental sulfur or other sulfur contaminant picked-up by refined hydrocarbon product such as gasoline, diesel, jet fuel, kerosene or fuel additive such as ether, which is pipelined in a pipeline used to transport sour hydrocarbon fluids, is reduced by controlling the level of dissolved oxygen in the refinery hydrocarbon product to which is to be pipelined, said dissolved oxygen level being held to a level of about 30 wppm and less, preferably about 20 wppm and less.  The dissolved oxygen level in the refined hydrocarbon product is controlled by reducing the amount fair injection employed in mercaptan or disulfide reduction production increases or by the use of oxygen scavengers prior to the introduction of the refined hydrocarbon product into the pipeline, or by limiting the exposure of the product to air in oxygen during transport or storage.

Abstract: Processes for tufting substrate or primary carpet backing (111) using conventional double needle bars (116, 112) but in which the needles may be shifted less than a full gauge. Processes of the present invention may employ a conventional double needle bar tufting machine (133) to which is added means for shifting or indexing the hook bar (134) laterally to the machine direction of the substrate being tufted. Timing of shifting of the hook bar (134) may be coordinated with timing of shifting of the needle bar (133) and advance of the substrate (111) through the machine to allow piles (132) to be tufted into the substrate (111) at any desired lateral position with respect to previously tufted piles. The invention creates additional pile color pattern alternatives and eliminates repetitive patterns otherwise necessitated by full gauge shifting. Elimination of repeat color sequences reduces matching color sequences on adjoining edges of adjacent carpet tiles made from such substrate which otherwise accentuate or highlight the seams between carpet tiles.
