Patent CA-2332264-A1 (CA)
Inventor: ESTES ROBERT ALAN
IPC: E21B47/022
Filed: 1999-05-13
Abstract: A processor uses signals from at least two GPS receivers and a 3-component accelerometer located on a stable non-magnetic platform to determine the roll, yaw and pitch angles of the platform, thus providing a measurement of geographic north. The processor also uses signals from a 3-component magnetometer on the platform to determine the magnetic north and thence the magnetic declination. A proton magnetometer is used to provide a check on the measurements of the 3-component magnetometer. Additionally, three single component magnetometers provide a measure of the local magnetic field gradient and serve to monitor artificially induced magnetic fields. An alternate embodiment of the invention uses at least three GPS receivers and may dispense with the 3-component of accelerometer to determine geographic north. Temporal local variations of the earth's magnetic field are tracked and used to correct conventional magnetic well surveys. For use in offshore drilling applications where the rig is on a drillship, the platform floats on water away from the drillship and tethered to a buoy. Signals from an inertial motion sensor are used by the processor to correct the observations of the GPS sensors, the magnetometers and the accelerometers for the motion of the platform in water.

Abstract: A method of modifying or altering the structure of a 1.alpha.-hydroxylated vitamin D compound to increase its biological activity by altering the conformational equilibrium of the A-ring to favor a chair conformation that presents the 1.alpha.-hydroxyl in the axial orientation. This is accomplished by either locking the A-ring chair conformation in a geometry having an axially oriented 1.alpha.-hydroxyl, or by the addition of one or more substituents to the A-ring which interact with other substituents in the molecule or on the A-ring to provide a driving force to the A-ring to adopt a chair conformation which presents the 1.alpha.-hydroxyl in the axial orientation.

Abstract: Cette invention a trait à une méthode d'éclairage d'un objet. Dans le cadre de cette méthode, on détermine en premier lieu la réflectivité spectrale d'une première zone distincte du point de vue spectral (10) et l'on recense la ou les parties de longueur d'onde de cette zone qui réfléchisse(nt) davantage la lumière émanant d'une source lumineuse qu'elle(s) n'en absorbe(nt) (et ce, jusqu'à quel point). On identifie ensuite la réflectivité maximale de cette partie de longueur d'onde, après éclairement par la source lumineuse, ainsi que le segment de la première partie de longueur d'onde dont la réflectivité est inférieure à un pourcentage précisé de la réflectivité maximale. On produit alors une image numérisée que l'on modifie pour détruire le segment à faible réflectivité de la première partie de longueur d'onde (22). On fixe ensuite l'image numérique modifiée sur un support (50) (une diapositive couleur, par exemple). On éclaire le support à l'aide de la source lumineuse (52) et l'image lumineuse ainsi produite est projetée sur l'objet (100).

Title: Method for cleaning artwork
Inventor: DECRUZ ADELE
IPC: B08B7/00
Filed: 1999-07-26
Abstract: The present invention is a method of cleaning artwork by removing contaminates from a painted or patina surface of the artwork. A  pulsed laser is used having a wavelength of between 2.3 and 3.3 µm, such as an Er.YAG having a wavelength of 2.94 µm, to stimulate the presence of an OH radical contained in the contaminant film layer to be removed or introduced to the paint surface contaminated film using an OH containing agent applied with a brush, cotton swab or spray. The surface to be removed is covered by a glass cover slip and has the laser energy impinged thereon. The laser energy interacts with the OH  radical present in the contaminant or introduced into the surface by the operator. The reaction of the laser energy with the OH radical deposits the contaminated film material onto the glass slide cover. Contaminants that remain on the paint surface can then be removed by scalpel or cotton swab using a wetting agent.

Title: Powder feeding apparatus having an adjustable width and method for adjusting the feed width of the apparatus
Inventor: RODENBERG PHILLIP R
IPC: B05C19/06
Filed: 1999-11-04
Abstract: A method and system are provided for adjusting a discharge width of a powder  feeder (10). The system includes a supply hopper (12) that is spaced from th e powder feeder. The powder feeder includes a receiving opening (22) and a discharge opening and at least one adjustable wall (26, 28). Preferably, two  adjustable walls are provided. Movement of the two adjustable walls provides  variations in the width of the discharge opening and therefore facilitates u se of the powder feeder on target volumes or target areas having different widths. A rotatable auger brush (18) is in communication with the supply hopper for causing powder withdrawn from the supply hopper to be transported  to the powder feeder and disposed uniformly across the receiving opening of the powder feeder. The brush is immersed within the powder and extends acros s the receiving opening of the powder feeder, and maintains a filled level powder feeder. The powder feeder is particularly well-suited for use in a coating apparatus, as well as dual-side coating apparatus.

Title: Composite materials with bulk decorative features and process for producing same
Inventor: SATZ RICHARD
IPC: B44C3/04
Filed: 2000-03-24
Abstract: A visually decorative material having bulk decorative effects which may be used as a surface covering or for creating decorative objects, and the method of manufacturing same. The material is formed of a pigmented castable liquid vehicle such as a resinous polymer or glass having dispersed therein a quantity of discrete particles which have a higher specific gravity than the liquid vehicle. The material is formed by pouring the vehicle-particle composite onto a suitable backing. As the liquid flows onto the backing, the particles sink and disturb the uniformity of the pigment distribution. This causes the desired bulk decorative effects in the form of "comet-tails" and other dimensionally extended streaks and curves. The backing may be removed after the castable liquid solidifies or may be left in place to create a laminate. As a floor-covering, the material may be poured in place onto a suitable sub-flooring. A protective surface coating may also be applied to the solidified casting.
