Title: Centrifugal deresination of pulp and paper process liquids
Inventor: ALLEN LAWRENCE HARVEY
IPC: B01D21/26
Filed: 1995-03-15
Granted: 2002-04-02
Abstract: A process for the removal of dispersed contaminants less dense than water from pulp and paper mill process liquids, comprises passing the liquid through a centrifuge and collecting the contaminants as a less dense fraction. The application of this invention to paper industry process liquids provides a means of removing a significant fraction of the wood resin and wood resin soaps from the process stream, thus enabling (1) a greater extent of reuse of filtrates and, hence, less effluents from mills, and (2) fewer problems from wood resin, such as deposit formation, loss of strength of product, and contamination of product with dirt particles.

Title: Monitored article dispenser
Inventor: PARKHURST LARRY E
IPC: G16H20/13
Filed: 1993-09-21
Granted: 1999-04-06
Abstract: A dispenser aids and monitors regimen-conforming use of medications provided in blister packages. A blister package and a separate, disposable sensor sheet (148) are loaded into a compact housing cont aining supervisory electronics (350), visual indicatos (392, 393, 394) and an audible alarm (396). The sensor sheet (148) consists of s ensing regions (310) corresponding to each individual compartment of the blister package. A connector (318) in the dispense r housing allows periodic scanning of the sensor sheet circuitry by the control circuitry (350) without adding connector componen ts of the low cost, disposable sensor sheet (148). When a medication is ejected through the blister package, a parameter associated with a corresponding region of the sensor sheet (148) is altered, thereby permitting the control circuitry (350) to monitor the dispensing event. Stored patient compliance data may then be reported remotely through an interface (352, 354) between the dispen ser and an external system for review by the pharmacist/physician.

Title: Molecular diagnosis of familial adenomatous polyposis
Inventor: KINZLER KENNETH W
IPC: C12Q1/6827
Filed: 1994-12-13
Granted: 2006-10-31
Abstract: A two-pronged method for diagnosis of genetic diseases can detect mutations in about 87 % of familial adenomatous polyposis (FAP) patients. One part of the diagnosis method employs in vitro protein synthesis from surrogate genes created by amplifying either cDNA or genomic DNA. The second part of the diagnostic method employs an allele-specific expression assay which distinguishes the amount of mRNA expressed in vivo from each of a patient's two alleles. These approaches are readily applicable to the diagnosis of other genetic diseases.

Title: Bandwith correlation means for paths in connection-oriented packet switching networks
Inventor: FEDYK DONALD W
IPC: H04L12/56
Filed: 1996-11-22
Granted: 2002-12-31
Abstract: An alternate path can be established in a connection-oriented packet switching network by correlating the bandwidth reservation of this alternate path with the bandwidth reservation of an active path on trunks through which both paths pass.  The alternate path that is established can have one or more of a number of different attributes that vary from the attributes of the active path.  The alternate path is established in a connection-oriented network with bandwidth correlation in three stages: a keying stage, a correlation stage and, a transfer stage.  An alternate path may be established without a double reservation of bandwidth, thus making efficient use of limited network resources.

Abstract: A correction curve is prepared by plotting 12CO2 concentrations and 13CO2/12CO2 concentration ratios which are determined on the basis of a calibration curve and 13CO2 and 12CO2 absorbances of gaseous samples having the same 13O2/12CO2 concentration ratio but known different 12CO2 concentrations. A gaseous test sample containing 13CO2 and 12CO2 as component gases is introduced into a cell, and spectrometrically measured. A 12CO2 concentration of the gaseous test sample is determined by way of the spectrometric measurement. A concentration ratio correction value is obtained on the basis of the correction curve and the 12CO2 concentration of the gaseous test sample thus determined. A measured 13CO2/12CO2 concentration ratio is divided by the concentration ratio correction value thus obtained for correction of the 13CO2/12CO2 concentration ratio. Thus, the measurement accuracy of the concentration ratios of the component gases can be improved.
