Title: Method for determining viability of a myocardial segment
Inventor: SAWADA STEPHEN G
IPC: A61K51/04
Filed: 2000-09-22
Abstract: A method of determining the viability of a hibernating or stunned myocardial segment comprises the administration of ribose, a vasodilator and an inotropic agent. The preferred agent is dobutamine, which has both a vasodilation and an inotropic effect. The segments may be identified by myocardial imaging by any known means, such as echocardiography, Thallium-201 tracing or positron emission tomography. Ribose is preferably given one minute to three hours prior to administration of the vasodilator and inotropic agents.

Title: Integrated optics probe for spectral analysis
Inventor: GROSS ERICH R
IPC: G01N21/35
Filed: 2000-10-10
Abstract: Percentage concentrations of constituents or color components of a sample ar e determined using a spectral analyzer with a wide illumination spot size and detector. The analyzer irradiates the sample, picks up diffuse reflectance o f individual wavelengths from the sample and spatially separates the diffuse reflectance into a response at individual wavelengths. The result is to simultaneously detect the intensities of the individual wavelengths in parallel from the sample being analyzed. Percentage constituents of a composite substance can be determined or, alternatively, the components of color in a sample can be determined by analyzing wavelengths of reflected light.

Patent CA-2389005-A1 (CA)
Inventor: POUGET MICHEL
IPC: A61M5/32
Filed: 2000-10-26
Abstract: The invention concerns a safety device for syringe equipped with a collapsible head. The inventive device enables, when the injection is over, the return element to move back the syringe body inside the sheath into a safe position, thereby causing the syringe body to retract into the sheath. Thus all accidental contact with said needle becomes impossible. By means of the collapsible head of the sheath which, in extended position, covers the part of the syringe body extending beyond the rear end of the sheath, the syringe is maintained in the sheath and cannot be released therefrom by its rear end.

Title: Method and apparatus for determining stone cells in paper or pulp
Inventor: CHOW ROSS S
IPC: G01N21/88
Filed: 2002-07-25
Abstract: Disclosed is a method and apparatus for determining stone cells within a sample of wood pulp or paper. According to the instant invention a portion of the sample is irradiated with light at a predetermined wavelength or within a predetermined range of wavelengths. The incident light causes those areas of the sample that are occupied by stone cells to fluoresce strongly relative to the background matrix of wood pulp or paper. The strongly fluorescing stone cells are registered digitally using a detector, or are observed visually by an operator viewing the sample through an ocular device. The absolute number of stone cells per unit area or a stone cell size-distribution-plot is obtained using one of automated or manual image analysis.
Patent CA-2395174-A1 (CA)
Title: Film cutter assembly
Inventor: NEIBERGER SEAN
IPC: B26D3/00
Filed: 2000-12-20
Abstract: The present invention relates to a film cutter assembly in which a blade housing slides along a pair of rails. The blade housing is formed of an upper portion for housing the blade. Either end of the upper portion has a rounded inclined shape from a bottom edge to form a sled shaped runner. The sled shaped runner extends beyond the blade such that the user is prevented from touching the blade. A lower portion of the blade housing slidables bilaterally in a cavity formed below the rails. A clearance is formed between the blade and the rails to allow the blade housing to easily slide over a film to be cut even if the film bunched or doubled over. The upper portion of the blade housing has a concave shape for allowing a user's fingers to easily grip the blade housing. Preferably, the rails are formed of a material which provides an attractive charge to attract the film to the rail and help hold the film flat before and after cutting. For example, the rails can be formed of flexible vinyl or acetal.

Abstract: An electric motor and its controller are specially adapted for variable speed applications. The stator of the motor has its main windings controlled by triacs. The triacs are placed to allow the main windings to operate in series at low speed and in parallel at high speeds. The firing delay of the operating triacs is controlled in both series and parallel winding operations to aid in smooth operation of the motor. The auxiliary winding is preferably left uncontrolled to contribute a regular sinusoidal component to the windings power at all times. The controller receives the speed command and figures firing delay and outputs triac control pulses at one of a plurality of settings to bring the motor to the selected speed. In this manner a simple, inexpensive, and continuously variable speed motor may be realized with good performance characteristics.

Abstract: A coated substrate comprises a strippable intermediate coating atop the substrate and a strip agent-permeable waterborne overcoat adhered to the intermediate coating, wherein the dried overcoat is less trippable and more wear-resistant than the dried intermediate coating. When the overcoat eventually becomes worn and must be renewed, a strip agent (e.g., chemical strip agent) can be applied to the overcoat. The strip agent penetrates the overcoat and attacks the intermediate coating, thereby enabling removal of the intermediate coating and overcoat without aggressive removal techniques such as sanding.

Patent CA-2410019-A1 (CA)
Inventor: AHLSTROM JOHN F
IPC: H04M11/02
Filed: 2002-10-24
Abstract: A switch mode power supple that may be used for a telephone entry system (TES) or the like with a power factor approaching 1Ø Rectified DC from a full wave rectifier is passed to a pair of inductors that are alternately sinking and sourcing current thereby drawing a more uniform input current because current constantly flows through the full wave rectifier to both of the inductors. A  pair of FETs, each connected to one of the pair of inductors, are alternately turned on and off such that current from the current sinking inductor is shunted to ground.  When one inductor is sinking current (i.e., through an active one the FETs) the other inductor is sourcing current to charge a filter capacitor and thereby provide an essentially constant unregulated voltage. The unregulated voltage at the capacitor is supplied to voltage regulators which in turn supply regulated voltage. At steady state, all current being supplied by the sourcing inductor is passed directly to and through the voltage regulator.

Title: High speed manufacturing process for precipitated calcium carbonate employing sequential pressure carbonation
Inventor: MATHUR VIJAY
IPC: D21H17/67
Filed: 2000-07-21
Abstract: A process for the production of precipitated calcium carbonate. A slurry of calcium hydroxide is agitated in a pressurized reactor, and carbon dioxide is provided under pressure to the reactor to produce precipitated calcium carbonate at a high reaction rate. Carbon dioxide is utilized at a high efficiency. Solubilized calcium ions and carbonate ions react to produce a calcium carbonate precipitate. Control of process conditions such as temperature, slurry concentration, and pressure, enables production of a desired crystal habit (including sclenohedral, rhombohedral, stacked rombohedral, or aragonite crystal structures), crystal size, or crystal aspect ratio. The precipitated calcium carbonate produced by the process under pressure is useful as either a paper filler or as an ingredient in paper coatings, and provides a paper product with improved preselected properties, which properties include opacity, density, and/or brightness.
