Patent CA-2213266-A1 (CA)
Inventor: TSURUOKA HIDEKI
IPC: C07K5/02
Filed: 1997-08-18
Abstract: An improved method for isolating and purifying a glutathione derivative is disclosed.  More particularly, the invention provides a method for isolating and purifying S-(1,2-dicarboxyethyl)glutathione or its pharmacologically acceptable salt from a reaction mixture available upon reacting glutathione or its salt with either fumaric acid or its salt or maleic acid or its salt, which comprises a first step of converting the S-(1,2-dicarboxyethyl)glutathione or salt thereof in the reaction mixture to thecorresponding copper salt, dissolving the copper salt in an aqueous solution of acetic acid, formic acid or propionic acid, and removing the contaminant glutathione, oxidized glutathione and fumaric acid copper salts with the aid of activated carbon and a second step of dissolving or suspending the isolated S-(1,2-dicarboxyethyl)glutathione copper salt in water and blowing hydrogen sulfide gas through the resulting aqueous solution or suspension to remove copper.

Title: Control apparatus for hydraulically operated vehicular transmission
Inventor: ISHIBASHI HIROMITSU
IPC: F16H61/02
Filed: 1997-08-21
Abstract: Even if a rotational speed of an engine has already increased due to slipping of a fluid torque converter at the time of start of downshifting, a smooth downshifting is performed. For that purpose, there is obtained a speed change developing degree function K(etrm) of the rotational speed of the engine at the time of start of downshifting, the developing degree being dependent on an increase in the rotational speed of the engine due to slipping in the fluid torque converter. The function K(etrm) is obtained with a speed ratio "etrm" of the fluid torque converter at the time of starting of downshifting as a parameter. A boosting correction value QDNOFFZ is computed by multiplying a reference correction value QDNOFFZO by K(etrm) (step S108-5). The hydraulic pressure of the hydraulic engaging element on the disengaging side during downshifting is boosted by the amount of QDNOFFZ (step S108-6).

Title: Method and apparatus for measuring total nuclear magnetic resonance porosity
Inventor: FLAUM CHARLES
IPC: G01R33/44
Filed: 1998-03-11
Abstract: A method and apparatus for measuring total nuclear magnetic resonance porosity of an earth formation traversed by a borehole is sensitive to fast relaxation times that can be associated with clay-bound water. The total porosity measurement includes, in addition to free fluid and capillary-bound porosity, the porosity of clay-bound water and microporosity. An oscillating magnetic field is produced within the borehole, according to a phase alternated sequence, such as the Carr-Purcell-Meiboom-Gill (CPMG) sequence or a similar pulse sequence, to induce signals in the volume of formation which are measurable by the NMR logging tool. A reduced echo spacing and improved signal-to-noise ratio allows the recovery of short T2 components. The spin echo signals are measured and a value is determined for each signal. The signal values are separated into a first set and a second set wherein the first set comprises the early-time echo signals and the second set comprises the remaining echo signals. The second set of echoes are sub-divided into a plurality of groups and a window sum value is generated for each group of the second set, thereby producing a plurality of window sums. An attribute of the formation is determined based upon the plurality of window sums and the value of each signal of the first set.

Inventor: THIEL ROBERT F
IPC: G01N33/574
Filed: 1996-09-27
Abstract: The present invention relates to a method for diagnosing prostatic adenocarcinoma (CAP) in a male human patient without requiring a biopsy. The total prostate specific antigen (PSA) level in the blood or serum of the patient is measured. If the patient has a total PSA level of between 2.5 ng/ml and 20.2 ng/ml, then the free PSA level in the blood or serum of the patient is measured. The proportion of free PSA (10) to total PSA (12) is calculated.  If this proportion is less than about 7 %, then the patient is diagnosed as having CAP. The present method can also be used on patients that have a total PSA of at least 10.1 ng/ml, but have also had a negative prostate biopsy.

Patent CA-2241659-A1 (CA)
Title: Method of maintaining constant concentrations of substances contained in an electrolytic treatment bath
Inventor: KOPP LORENZ
IPC: C25D21/14
Filed: 1997-01-10
Abstract: The invention relates to a method for maintaining constant concentrations of substances contained in an electrolytic treatment bath, preferably in baths with aqueous solutions. In order to regenerate the continual depletion of chemicals, substance concentrates are added to the baths according to known methods. The rapid increase in concentrations of damaging substances in the processing solution is disadvantageous. In order to reduce this build-up, a further metering method is known, namely the continuous replacement of bath solution by creating a bath overflow. The addition of bath solution with the bath concentration is balanced out by the overflow. As a consequence of evaporation and entrainment this method also leads to the fact that the operating concentration cannot be maintained for a long period of time in chemically critical baths.        With the invention, this problem is resolved by continuous or intermittent removal of bath solution in a defined quantity and addition of fresh bath solution preferably in the same quantity. The changes in the concentrations of substances in the bath occurring through evaporation and entrainment are compensated for completely independently of the metering.
