Patent CA-2064712-A1 (CA)
Inventor: SCHOENDORFER DONALD W
IPC: A61M1/30
Filed: 1991-06-12
Abstract: Procédé et appareil de séparation par machine de sang et de constituants du sang consistant en l'administration améliorée d'anticoagulant à la sortie de suspension de globules rouges. On ajoute un anticoagulant (20) au sang total entrant (13) en une dose suffisante pour empêcher la coagulation du sang total dans le chemin d'écoulement en amont du séparateur (46) de constituants du sang, mais en une dose insuffisante pour empêcher la coagulation de la suspension des globules rouges créée par le séparateur. On ajoute un anticoagulant (20) à la suspension de globules rouges en aval (50) du séparateur (46) afin d'empêcher la coagulation. Le fait d'ajouter un aliquot supplémentaire d'anticoagulant à la suspension de globules rouges permet de réduire ou d'éliminer la dose d'anticoagulant ajoutée au sang total avant la séparation, ce qui a pour effet d'augmenter le rendement plaquettaire pendant l'étape de séparation des constituants du sang.

Title: Frequency doubler with a variable delay circuit and exclusive or gate
Inventor: TATSUMI SATOSHI
IPC: H03K3/017
Filed: 1992-04-29
Abstract: A doubling circuit for adjusting the duty ratio of an output signal automatically and implemented as a digital circuit.  A variable delay circuit delays an input signal while an exclusive-OR (EOR) gate produces EOR of the output signal of the delay circuit and the input signal.  The resulting output of the EOR gate has a frequency double the frequency of the input signal.  A low pass filter (LPF) filters the output signal of the EOR gate to produce a mean voltage thereof.  An integrating circuit integrates a difference between the output voltage of the LPF and a reference voltage.  The delay of the variable delay circuit is controlled by the output of the integrating circuit.  As a result, the doubled signal from the EOR gate has the duty ratio thereof automatically adjusted.

Title: Cleaning of cuttings from drilling operations
Inventor: BAILEY MARSHALL G
IPC: B01D11/02
Filed: 1990-11-23
Abstract: A method of removing oil from oily cuttings obtained from a drilling operation of oil or gas wells, in which the cuttings are exposed in an extractor chamber (12) to a solvent for the oil, such as toluene or other suitable stabilised gasoline fraction. The solvent thus dissolves the oil, and the cuttings may then be separated from the solvent with the oil dissolved therein on a fine mesh conveyor belt. Alternatively the cuttings and solvent may be formed into a slurry in an agitating vessel and then pumped to a solid bowl decanting centrifuge (26) from which the solids are fed to a dryer (18).

Title: Liquid-liquid contact apparatus having fire suppression capability
Inventor: EBERTS DONALD H
IPC: B01F3/08
Filed: 1992-05-20
Abstract: ABSTRACT           A liquid-liquid contacting apparatus is provided having the capacity to control and contain a fire occurring within a separator vessel.  Mixing of two liquid phases such as an organic and an aqueous solution may be advantageously conducted when the two phases are supplied at steady flow rates.  Variations in the rates of supply of the phases are compensated for by pumping each liquid at a constant flow rate higher  than the maximum flow rate provided by the supply, and permitting recirculation of a disengaged phase in the amount necessary to meet the demand of the system.  The organic solution having a lower density than the aqueous solution rises within a separator vessel and may be ignited upon its upper surface.  By flooding the vessel with a third nonflammable liquid such as water, the liquid level within the vessel is raised until the organic solution is removed by flowing over a channel weir within the vessel and is drained away through a fluid trap.   The trap prevents the surface fire from propagating beyond the vessel and weir.

Filed: 1992-06-25
Abstract: ABSTRACT OF THE INVENTION      A plastic covered nonconducting substrate with an electrical circuit means is secured to the extent to withstand the presence of liquids in contact with the substrate.  The covered substrate can have the substrate with one or more fluid preconditionable electrical components, a housing secured to the substrate to maintain contact of the preconditioning fluid with the electrical component like a sensor, and moisture impervious seals to cover openings in the housing for the disposition of the preconditioning fluid in the housing for contact with the electrical component on the substrate.  The housing can have one or more parts and have one or more channels for containing the preconditioning fluid.          The substrate with electrical components can be with a sensor assembly generally and have an improved electronic wiring board having a thermistor and at least one sensor supported, in close relation, one to the other, on one side of the board and a heater supported on the other side of the board to provide heat in response to temperature sensed by the thermistor, to at least the region where the thermistor and the sensor are positioned on the board to control the temperature of the region of the board within a narrow distribution of temperatures.          The sensor assembly with or without the improved wiring board can be used in a single use disposable fluid sample collector, sensing, and calibration device.  This device contains a collector like a syringe, with one or more analyte sensors, and a calibrator for calibrating the sensor.  These can be pre-assembled; the analyte sensor may be connected to a self-contained monitoring instrument or analyzer which processes the signals from the sensor and displays the information to the operator.          Also the sensor assembly can be used in a portable, ready-for-use analyte measuring device for the measurement of multiple sequential fluid samples.  The device has a disposable cartridge, a calibrating fluid external to the cartridge and an analyzer.  The cartridge has a housing, inlet for introduction of fluids into the housing, sensor element in fluid connection with the inlet, at least one unidirectional valve in fluid connection with the sensor element, and a waste collection area or reservoir in fluid connection to the valve.          The sensor apparatus alone or in the single use or multiple use mode can be sealed in a hermetically sealed layer that is impervious to gas and moisture and is a diffusion-tight boundary or barrier and that contains at least one preconditioning fluid.  The preconditioning fluid is an activating fluid when the sensor is in an unsealed housing and can be either or both the activating fluid or a controlled-content fluid when the sensor is in a sealed housing.

Abstract: Abstract Image-pattern-specific separation values are calculated in each case per column for a separation image (PTR) of standardized width (bstd), with the aid of a separation classifier, and the column having the maximum separation value is defined as the right-hand separation column (tr). On the basis of the separation column (tr) pre-determined by the separation classifier, an attempt is made, starting from the upper pixel of the separation column, to find a separation path which, in the absence of a white column, is formed within a separation region, which is located on both sides of the separation column, partially by contour tracing and, if no white path can be found by contour tracing, partially by forced separation along the separation column.
