Patent CA-2106289-A1 (CA)
Inventor: IKEDA TOSHIKI
IPC: A61N1/04
Filed: 1993-09-15
Abstract: An electrically conductive polymer gel is composed a crosslinked polyacrylamide polymer including electrolytic salt, water and polyhydric alcohol uniformly dissolved therein, the water and the polyhydric alcohol being major components of said polymer gel.  The polyacrylamide series polymer in the gel has properties of hydrophilic and nonelectrolyte.  Therefore, a desirable connection between the gel and the electrode can be achieved with low impedance.  Moreover, the polyhydric alcohol reduces the drying speed of the electrically conductive polymer gel, thereby preventing an increase in the impedance due to the dryout of the gel.  Therefore, the electrically conductive polymer gel of the present invention permits an accurate measurement of an electrical phenomenon in the organism for long periods of time.

Patent CA-2123426-A1 (CA)
Inventor: PELRINE BRUCE P
IPC: C10G69/12
Filed: 1991-11-22
Abstract: 2123426 9310066 PCTABS00022 Aromatic structures can be introduced into the molecular structure of polyalpha-olefin (PAO) lubricant oligomers by subjecting the polyalpha-olefin to a dehydrocyclization reaction which converts a portion of the pendant or branching alkyl groups in the recurring polymeric unit of PAO to aromatic structures. When the starting material for dehydrocyclization is PAO prepared by oligomerization of C6-C20 alpha-olefins in contact with reduced chromium oxide catalyst on porous support the dehydrocyclization reaction produces a lubricant oligomer with increased aromaticity without significantly degrading the viscometric properties of the feedstock lubricant, particularly the high VI of the starting material.  The aromatic structures introduced lend increased thermal stability, wear resistance and solubilizing characteristics to the liquid lubricant oligomers so modified. The polyalpha-olefins produced by the dehydrocyclization process comprise novel compositions of matter containing up to five weight percent of aromatic structure attached as pendant groups to the backbone of the polyalpha-olefin structure.

Title: Automatic refiner load control
Inventor: ALLISON BRUCE J
IPC: D21D1/30
Filed: 1994-08-17
Abstract: The load on a refiner motor is controlled by adjusting the motor load setpoint by monitoring load applied by the refiner and the plate gap between the refiner plates to define the curve of the load versus plate gap relationship. This slope of load versus plate gap relationship is estimated and when the sign of the slope of the curve changes sign indicating operation in an unstable zone of pad collapse and based on the tendency for the refiner to be in the unstable operation zone over a selected period of time exceeding a preset limit adjusting the setpoint lower to approach more closely the maximum load applied over the selected time.
