Patent CA-2074594-A1 (CA)
Inventor: ALLEN LINUS S
IPC: E21B41/00
Filed: 1992-07-24
Abstract: A borehole logging tool is lowered into a borehole traversing a subsurface formation and a neutron detector measures the die-away of nuclear radiation in the formation. A model of the die-away of nuclear radiation is produced using exponential terms varying as the sum of borehole, formation and thermal neutron background components.      Exponentially weighted moments of both the die-away measurements and die-away model are determined and equated. The equated moments are solved for the ratio of the borehole to formation amplitude components of the measurements. The formation decay constant is determined from at least the formation and thermal neutron background terms of the weighted measurement aril model moments. An epithermal neutron lifetime is determined from the formation decay constant. This epithermal neutron lifetime and the amplitude ratio are used by a trained neural network to determine a lifetime correction and an apparent standoff. A standoff corrected lifetime is determined from the epithermal neutron lifetime and the lifetime correction. A porosity log of the formation is produced which is corrected for detector standoff from the borehole wall as a function of the standoff corrected epithermal neutron lifetime calibrated in borehole models of known porosities.

Title: Impeller for treating molten metals
Inventor: ECKERT CHARLES E
IPC: F27D27/00
Filed: 1992-09-25
Abstract: Abstract An improved impeller head is provided for treating molten metals and other liquid systems with a gas.  A multiple-vaned impeller head is adapted for mounting on a hollow impeller shaft for rotation within the liquid.  The edges of the impeller vanes are extended by an axial groove which intercepts the hub and the vanes of the impeller head.  Extension of the trailing edge of the vanes creates greater turbulence in the liquid as the impeller is rotated in the liquid and increases the impeller's efficiency. The impeller vanes may also have canted leading surfaces which create an upward axial flow of liquid to discourage formation of a surface vortex.  Multiple impellers may also be mounted on a shaft in the vessel and the gas may be introduced remotely.

Title: Heater, a method of manufacturing the same, and an anti-condensation mirror incorporating the same
Inventor: OHASHI KEIICHI
IPC: H05B3/14
Filed: 1993-05-10
Abstract: A heater includes a heating element made of a PTC thermistor, electrodes formed on upper and lower surfaces of the heating element, flat metallic terminals connected to the electrodes, lead wires connected to inner surfaces of the metallic terminals that face each other, and an insulating  case  for  covering  exposed  portions  of  the heating  element,   electrodes,   and  of   the  metallic terminals and the connections between the lead wires and the metallic terminals.  With this structure,  since no bumps are produced on the outer surfaces of the metallic terminals by connecting the lead wires to the metallic terminals, the thickness of the insulating case over the metallic terminals is reduced.  This allows a reduction in the thickness of the heater and an improved heat transfer between the heating element and the heated object.   A method of  manufacturing the heater includes the steps of forming a heating unit by connecting the flat metallic terminals to the electrodes and connecting the lead wires to the metallic terminals, disposing the heating unit on a predetermined  position  of  the  base  section  of  the insulating case, and sealing the exposed portions of the heating unit in the insulating case by injection-molding a cover  section  of  the  insulating  case with  insulating material after disposing the base section in a mold. This method enables the heating unit to be easily covered with the insulating case, thereby facilitating the manufacture of the heater.

Title: Evaluating furnish behavior
Inventor: GESS JEROME M
IPC: G01N33/34
Filed: 1992-09-24
Abstract: A drainage tester evaluates the reaction pattern of one or more reactions in a paper pulp furnish to predict behavior of the pulp on a paper line. The tester includes a mixing container in which an additive is mixed with the slurry under conditions that prolong the reactions in the container such that they take longer than the same reactions on a paper line. The mixer can also mimic the kinetic conditions (such as mixing by turbulence or passive diffusion) under which the additive is mixed with the furnish on the paper line. A test container has a screen bottom that separates furnish solid from slurry water by developing a pressure differential across the screen. An intermediate container is positioned between the mixing container and test container to provide a constant hydrostatic head on furnish transferred to the test container.  A sensor above the screen in the test container monitors changes in the optical characteristics of a sheet formed on the screen to automatically determine the drainage time of the formed sheet.  Sequential equal volume aliquots of furnish are withdrawn from the mixing container and sent to the test container at preselected time intervals after chemical additives are mixed with the furnish in the mixing container. Physical characteristics of the sheet, such as fines retention, drainage time and visual appearance, are recorded as a function of time from addition of additive to the mixing container. Behavior of the sheet on the paper line can be predicted in this manner to help an operator efficiently operate a paper machine system.
