Patent CA-2087801-C (CA)
Inventor: HOULACHI GEORGE
IPC: G01N27/42
Filed: 1993-01-21
Granted: 1996-08-13
Abstract: A method and an apparatus for on-line monitoring the quality of a purified metal sulphate solution is disclosed.  The method comprises the steps of depositing metal from the purified metal sulphate solution onto a working electrode submerged in the solution by passing constant current through the solution at a current density in the range of 25 to 150 mA/cm2 for a predetermined time interval, dissolving the metal deposited on the working electrode by reversing the polarity of  the potential applied between  the working  electrode and a  counter electrode so as to pass a reverse current of the same current density through the solution until all zinc is removed from the working electrode as sensed by a sudden change in electrode potential, deriving the quality index of  the  solution  by  calculating  the  ratio  of  the dissolution time over the deposition time, and restoring the surface of the counter electrode by effecting the dissolution  of  the  metal  deposited  on  the  counter electrode at the end of each measurement.

Abstract: A positioning housing assembly,  for an  infra-red thermocouple sensor of the type having a generally cylindrical sensor case with a sensing face at one axial end thereof and one or more electrical conductors at the other end thereof, includes a cylindrical housing member having a central bore that telescopically receives a sensor case.  A frusto-conical reflective surface, having a mirror-like finish, at one end of the housing, concentrates infra-red rays toward the sensing face of the inserted sensor.  The frusto-conical surface may be formed integrally with the housing or it may be carraied by a separable adapter that telescopically couples with the sensing end of the housing.  A separable handle attaches to the end of the housing remote form the sensing face, and includes a conductor conduit for guiding conductors away from a sensor within the housing to the exterior of the housing.  The housing further includes a set screw movable to clamp the sensor within the central bore.  Positioning legs extend axially from the housing near the sensing end, to control the distance between the sensing face of the sensor and a test surfacethat is being monitored by the sensor. The axial extent of the positioning legs may be adjusted by moving the legs axially relative to the housing;  in one embodiment the legs are attached to a positioning bracket that is slidably movable relative to the housing, while in another embodiment the legs slide within axially aligned bores formed directly in anintegral portion of the housing. Clamping screws are provided for locking the legs or the movable bracket in position relative to the housing.  In a further improvement of the invention, the reference surfaces at the free ends of the positioning legs may be rotable rollers,  for facilitating movement of the housing assembly from place to place along a surface that is being monitored.  Calibration marks on the housing or on the legs further facilitate accurate and reproducible positioning of the legs relative to the housing.

Title: Acid-anhydride esters as oil field corrosion inhibitors
Inventor: ALFORD JOHN A
IPC: C09K23/42
Filed: 1993-05-28
Granted: 1997-05-27
Abstract: A corrosion inhibitor with excellent film forming and film persistency characteristics may be produced by first reacting C18 unsaturated fatty acids with maleic anhydride or fumaric acid to produce the fatty acid Diels-Alder adduct or the fatty acid-ene reaction product.  This adduct or reaction product is further reacted in a condensation or hydrolysation reaction with a polyalcohol to form an acid-anhydride ester corrosion inhibitor.  The ester may be reacted with amines, metal hydroxides, metal oxides, ammonia, and combinations thereof to neutralize the ester.  Surfactants may be added to tailor the inhibitor formulation to meet the specific needs of the user (i.e., the corrosion inhibitor may be formulated to produce an oil-soluble, highly water-dispersible corrosion inhibitor or an oil-dispersible, water-soluble corrosion inhibitor).  Suitable carrier solvents may be employed where needed to effectively disperse the corrosion inhibitor formulation.

Title: Table saw assembly
Inventor: MCINTOSH GEORGE A
IPC: B23D45/06
Filed: 1994-03-16
Granted: 2000-08-22
Abstract: In general, table saws can be used in a stationary mode only, i.e. the saw blade is fixed in one position. A relatively simple saw assembly which can be used with a ordinary circular saw includes a table with a slot in the top surface thereof for slidably receiving the blade of a saw mounted on a slide beneath the table. The slide is movably mounted on a arcuate track on a carriage for permitting tilting of the blade to make angled cuts. The saw is connected to the slide by a cantilever structure, which permits changing of the amount of blade projecting above the table top, i.e. raising and lowering of the saw to alter the depth of cut. The carriage, is mounted on rails extending longitudinally of the table. A handle is connected to the saw and projects upwardly through the slot to a location above and in front of the blade for manual movement of the carriage, the slide and the saw. The handle is releasably locked in the elevated use position, and can be released and rotated to a position completely beneath the table top. With the handle in the lower position, the carriage is locked in one position on the rails, and the saw is used in the same manner as a conventional table saw.
