Patent CA-2386538-A1 (CA)
Inventor: LINGARD SIMON
IPC: G05B17/02
Filed: 2000-10-03
Abstract: Computer method and apparatus determines state of physical properties, i.e. product quality, of a chemical manufacturing process. A steady state modeler  (15) provides a rigorous steady state model of the process and instantaneous  state of physical properties. An estimator (21) or inferential sensing membe r determines state of the physical properties over time based on the steady state (instantaneous) values of the physical properties. To that end, a dynamic model of the subject process is formed from the steady state model. The computer method and apparatus may be part of a network such that laboratory and sensor measured process data is made accessible by the steady  state modeler and the estimator, and the estimator provides process paramete r values for maintaining state of the physical properties. The network also enables online and user-interactive access to the steady state model, the dynamic model and/or the parameter values for enabling control of the subjec t process.

Title: Dna encoding the human serine protease t
Inventor: QI JENSON
IPC: A61P25/00
Filed: 2000-08-30
Abstract: Here we describe the molecular identification of a cDNA encoding a novel serine protease we have termed protease T. The deduced amino acid sequence encodes a prepro form of 290 amino acids, and its alignment with other well-characterized serine proteases indicates that it is a member of the S1 serine protease family. We have found that the protease T mRNA is expressed in stomach, testis, retina, fibroblasts, spinal cord, and several regions of the brain. Protease T mRNA is also found in leukocytes and in the Jurkat (ATCC TIB-152) T cell line. Thus, this protease is potentially involved in gastric, testicular, retinal, dematological, neurological/neurodegenerative and/or immunological disorders. The protease T gene maps to human chromosome 16p13.3 which is near the tryptase locus. Enzymatically active protease T, we have generated, is amenable to further biochemical analyses for the identification of physiological substrates and specific modulators.

IPC: B44C5/08
Filed: 2002-06-28
Abstract: A kit for glass art in which a blank is cut from covered sheet plastic to a shape that encompasses a picture including artistic designs drawn on the covering. The artistic designs are cut out to create artistic openings through the surface of the plastic blank, each opening defined by edges having a thickness. An indentation is machined along the center of the thickness of the entire edge of each opening. Stained sheet glass is cut and ground by conventional methods to pieces which fit within matching openings in the plastic blank. The edges of the openings and stained glass pieces are foiled with foil tape and the glass pieces are soldered within their matching openings in the plastic blank with heat and melted solder. The covering of the plastic blank is removed to reveal the picture made of stained glass designs within the plastic blank of the kit.

Title: Method and apparatus for determining the cerebral state of a patient with fast response
Inventor: VIERTO-OJA HANNA E
IPC: A61B5/16
Filed: 2001-10-12
Abstract: A method and apparatus for ascertaining the cerebral state of a patient. The  method/apparatus may find use in ascertaining the depth of anesthesia of the  patient. In one embodiment, the entropy of the patient's EEG signal data is determined as an indication of the cerebral state. A frequency domain power spectrum quantity is obtained from the patient's EMG signal data. The latter  quantity can be updated more frequently than the EEG entropy due to its high er frequency. The EEG entropy indication and the EMG power spectrum indication can be combined into a composite indicator that provides an immediate indication of changes in the cerebral state of the patient. In another embodiment, the frequency range over which the entropy of the biopotential signal from the patient is determined is broadened to encompass both EEG signal data and EMG signal data and the entropy so determined used as an indication of the patient's cerebral state.

Title: Use of eicosanoids for tissue engineering
Inventor: MARTIN IVAN
IPC: C12N5/02
Filed: 2001-05-28
Abstract: Tissue engineering is the development of biological substitutes to restore, maintain, or improve tissue function. One strategy that has been created to regenerate new tissue comprising the steps of providing cells, expanding the  isolated cells in a first culture medium in which the cells lack differentiated functions and redifferentiating the expanded cells in a secon d cell culture medium. The present invention provides an improved method for tissue engineering. In particular the method provides specific biochemical factors to supplement cell culture medium during the redifferentiation proce ss with the goal of regenerating tissue equivalents that resemble natural tissu es both structurally and functionally. These specific chemical factors induce and/or accelerate and/or promote the redifferentiation of the previously expanded cells. Specifically, the invention provides a method for redifferentiation of mammalian or human chondrocytes in the presence of eicosanoids, precursor of eicosanoids, and/or mediators of wound healing acting in concert with eicosanoids.

Title: Apparatus and method for automatically achieving and maintaining congruent control in an industrial boiler
Inventor: GUNTHER JOHN C
IPC: G05D11/08
Filed: 1995-08-24
Abstract: A control system for automatically achieving and maintaining a desired sodium/phosphate ratio and phosphate concentration of the boiler water in an industrial. boiler for minimizing corrosion. The system uses an adaptive controller that models the boiler which enables the system to predict boiler pH and phosphate concentrations at any future time given the feed rates, feed concentrations of high and low sodium/phosphate stocks, blowdown rate, mass of the boiler water, initial boiler phosphate concentration and initial pH. Once these future concentrations are determined, the controller then determines which feed rates will return the current boiler water state to, and then maintain the boiler water at, the desired sodium/phosphate congruency ratio in the least amount of time. Where the controller determines that it is not possible to move the current boiler water state to the desired congruency setpoint, the controller determines a feed rate program that will move the current boiler water state to the attainable steady state point closest to the desired setpoint. An alternative embodiment fixes the phosphate concentration by ratioing the phosphate feed with the blowdown rate while continuously monitoring blowdown pH. This arrangement allows for the control of sodium by switching between the high and low ratio sodium/phosphate stocks based on the measured pH with respect to the pH setpoint.
