Abstract: A stable sensor designed to detect accurately the total NOx concentration under 100 ppm in terms of the NO gas concentration is made up of a first cell and a second cell with a gas diffusion aperture provided between the two cells. The first cell has a partition wall of a substrate of oxygen ion conductor containing zirconia as the main component and permitting a gas to be detected to  enter  the  zirconia  substrate;  oxygen  pumping electrodes are also formed on the first cell substrate which functions to expel oxygen in an atmosphere of the first cell to the outside and to reduce NO2 of the NOx gas to be detected to NO gas.  While NO gas entering through a gas diffusion aperture between the two cells flows into the second cell, a measurement is made of an electromotive force between a NO detection electrode formed in the second cell and a counter electrode also formed therein or a counter electrode formed on the reverse side of the zirconia substrate,  since such electromotive force corresponds to the level of the NO gas concentration and thus provides the total NOx concentration.

Title: Systems and methods for examining heart tissue
Inventor: WHAYNE JAMES G
IPC: A61B5/296
Filed: 1996-02-16
Granted: 2004-06-29
Abstract: Systems and methods use an array (20) of multiple electrodes (24) supported for operative association with a region of heart tissue, in tandem with a roving second electrode (36) supported for movement relative to the multiple electrodes for operative association with selected different regions of endocardial tissue within the heart. An analog or digital processing element (32) conditions one of the multiple electrodes and the roving electrode to emit a pacing signal while the other one of the multiple electrodes and the roving electrode records paced electro-grams occurring as a result of the pacing signal. A template of cardiac event of known diagnosis sensed using the array of multiple electrodes is input. A sample of a cardiac event acquired by pacing from at least one roving electrode and sensed with the array of multiple electrodes is input. The processing element and method electronically compare the sample to a template and generate an output.

Abstract: A cytological specimen analyzer includes an image capture apparatus, a mapper and a screening station. The mapper receives digital images of regions of a slide containing a cytological specimen and determines if each of the regions contains cytological material. The mapper analyzes the image of each region, pixel by pixel, and if the region contains cytological material then the coordinates of the region are stored along with a focal position for the region and a value indicative of the amount of cytological material in the region. Upon analysis of each region on the slide, the mapper determines the most efficient path to be traveled between regions containing cytological material to minimize the viewing time of an operator at the screening station. Upon request by the screening station, the sequence of the aforesaid coordinates, which is indicative of the most efficient path, are transmitted to the screening station.

Title: Laser opto-acoustic imaging system
Inventor: ORAEVSKY ALEXANDER A
IPC: A61B17/00
Filed: 1997-01-31
Granted: 2010-04-20
Abstract: The present invention provides a system and principles of laser photo-acoustic imaging and tomography. The basis for laser photo-acoustic tomography is the time resolved detection of laser induced transient stress waves, selectively generated in absorbing tissues of diagnostic interest. Such a technique allows to visualize absorbed light distribution in turbid biological tissues irradiated by short laser pulses. Laser photo-acoustic tomography can be used for detection of tissue pathological changes that result in increased concentration of various tissue chromophore such as hemoglobin or development of enhanced micro-circulation in diseased tissue. The invented technology combines the advantages of pulsed laser excitation with time resolved detection of acoustic transients. The invented technology can be used for determination of optical heterogeneities in biological tissues. These heterogeneities include blood vessels, tissue layers, abnormal tissues and damaged tissues with further reconstruction of 3D tomographic images of human organs or portions thereof.

Title: Regenerative oxygen preheat process for oxy-fuel fired furnaces
Inventor: KOBAYASHI HISASHI
IPC: F23L15/02
Filed: 1999-01-04
Granted: 2003-11-18
Abstract: A method and apparatus for supplying oxygen to an oxy-fuel fired furnace that has been preheated by heated flue gas recycled from the furnace. One or more regenerators are provided each having at least a first and a second regenerator bed. The beds are alternately cycled so that one is being preheated with hot flue gas exhausted from the furnace while the other is preheating oxygen through its already heated bed for supply to the furnace burner. The amount of hot flue gas supplied to the regenerator beds is controlled by continuously venting a portion of the total furnace flue gas so as to bypass the regenerators, and the regenerator beds are purged of residual oxygen by recycled cooled flue gas which is then supplied to the furnace before the regenerator beds are heated by the flue gas.

Abstract: A composite laminate panel suitable for building containment vessels, and in particular, suitable for building double hull oil tankers.  The laminate has two facing metal layers structurally bonded to a polyurethane elastomer core. The laminate is used in various hull components, such as the hull plates, longitudinal girders, transverse frames and bulkheads. The laminate is used to build the inner hull and outer hull, and may be used to build the structural supports between the inner and outer hulls. The innermost layer of inner hull contains the ship's cargo. The elastomer core of the inner hull laminate isolates the innermost hull skin from cracks, thereby preventing a loss of cargo such as oil into the environment, when the outer hull is pierced, penetrated or ruptured in an accident or grounding.

Title: Sterilization of organs and prostheses with coupling agents
Inventor: GIRARDOT JEAN-MARIE
IPC: A61L2/18
Filed: 1998-02-09
Granted: 2008-01-29
Abstract: Heart valves or other components for replacement of heart or other bodily organs and tissue prostheses or synthetic prosthetic materials are effectively sterilized by treatment with a coupling agent known to creat e amide linkages between amines and carboxylic acids in the presence of a lower alkanol. Such treatment has been shown to be bactericida l when carried out at 40 .degree.C for over 1 hour. The sterilization treatment preferably employs EDC as a water-soluble coupling agent, plus an optional coupling enhancer such as sulfo NHS or NHS, in the presence of isopropanol or an equivalent alkanol. Such sterilization treatment is preferably carried out at a temperature above ambient temperature in a buffered aqueous solution. The treatment leaves no residual s other than ones which are nontoxic and biocompatible, does not affect the resistance of the tissue to thermal denaturation and to digestion by proteolytic enzymes, and surprisingly also increases the resistance of fixed biological tissue to calcification.

Abstract: The invention provides a back spin swivelling device for a downhole rod pump, for backing off drive strings which may be under torque. The device of the invention is particularly suited for use with progressive cavity pumps (PCP), and for the release of torque in a drive string through "back spin". The device comprises a housing having an opening at a bottom end adapted to receive a rotatable shaft and having means for attachment to an external support at a top end; said rotatable shaft being partially housed within the housing and projecting from the bottom end of the housing, the shaft having at its bottom end means for attachment to a drive string; and means for mounting the shaft rotatably within the housing. The shaft and the means for attachment to the drive string are substantially symmetrical about their common axis of rotation, and provide no point of articulation between the shaft and the drive string. In a preferred embodiment, the device includes shock absorbing means for damping longitudinal displacements of the shaft. The symmetrical design of the rotating parts and the linear attachment of the shaft to the drive string greatly improve the safety of the device in comparison with rod pulling devices of the prior art, avoiding equipment failure and possible injury due to flying apart of the device under the influence of "wobble" at high angular velocities.
