Title: Oilwell leak containment apparatus for a completed oilwell
Inventor: HOLTBY QUINN A J
IPC: E21B41/00
Filed: 1999-01-07
Abstract: An oilwell leak containment apparatus for a completed oilwell includes a body segmented into two or more segments.      Each of segment has a non-mating edge and a mating edge. The non-mating edge has an upstanding containment wall. When the segments are coupled together to form the body the upstanding containment wall extends around a peripheral edge of the body and defines a liquid containment cavity. The mating edge mates with an other segments. Each mating edge has an arcuate portion. When the segments are coupled together to complete the body the arcuate portions form a circular collar. The segments are connected together with quick release couplers.      It is preferred that the quick release couplers be positioned within the liquid retaining cavity for ease of access.

Title: Process for producing a reduction gas for reduction of metal ore
Inventor: KASTNER WALTER RAINER
IPC: C21B13/14
Filed: 1997-07-09
Abstract: In a process for producing a hot reduction gas containing Co and H2 for reducing fine-grained metal ore, particularly iron ore, the reduction gas is formed by gasification of carbon-containing materials, particularly coal, under addition of oxygen in a gasification zone and subsequently cooled to a reduction gas temperature conducive to the reduction process. To produce a reduction gas of greater thermodynamic stability, H2O and/or CO2 are added to eliminate the Boudouard and heterogeneous water gas reaction and teh concomitant warming of the reduction gas.

Cet accroissement de poids n'est pas simplement lié à un accroissement du pourcentage d'amidon contenu dans la graine.
Patent CA-2264996-A1 (CA)
Title: Sealing device for axial flow turbine
Inventor: SUZUKI TOSHIO
IPC: F01D25/00
Filed: 1999-03-05
Abstract: A sealing ring is formed by arranging a plurality of segments around the shaft of a rotor of an axial flow turbine with their outer parts received in a holding groove formed in an inner ring included in a nozzle diaphragm. Flat plate springs press the segments of the sealing ring radially inward, and curved plate springs press the segments of the sealing ring radially outward. The pressing forces of the flat plate springs and the curved plate springs are determined so as to compensate the differences in pressing forces acting on the segments of the sealing ring attributable to the respective own weights of the segments of the sealing ring. The flat plate springs and the curved plate springs prevent the irregular movement of the segments of the sealing ring, ensure the smooth radial movement of the segments of the sealing ring, and prevent contact between sealing fins attached to the segments of the sealing ring and the shaft of the rotor of the axial flow turbine.

Abstract: A rain gutter guard assembly for preventing accumulation of debris in a gutter while directing water from the roof into the gutter is provided. The guard includes a body with an upper flat planar portion that is positioned under the shingles to hold the guard in place. A lower planar body portion extends over the gutter channel. A longitudinally extending flexible panel between the upper and lower panels provides a twisting ability to the guard.     The nose of the guard mates with the top front lip of a gutter. The gutter guard clip incorporates a snap-lock feature to secure the gutter guard to the gutter while maintaining the proper placement and alignment of the gutter guard. The clip also features an anti-runoff ledge to prevent water flowing from the gutter guard from being diverted by the clip off the front of the gutter, rather than into the gutter. The clip includes a self-positioning ledge on the bottom of the clip to correctly position the clip on the gutter. The gutter guard assembly further includes a universal end cap that can be applied to either end of the gutter guard. The cap prevents birds and other animals from entering the gutter/gutter guard channel.

IPC: B42D5/02
Filed: 1999-04-16
Abstract: A mailer type business form is constructed from an intermediate having a plurality of pressure activated cohesive cooperating patterns, and a card is mounted on or with the intermediate. Despite the fact that a card is included, because of the provision of surface manifestations in the intermediate, and/or because of the relative thicknesses of the card and the intermediate, the mailer may be sealed by steam rolling rather than requiring selective edge sealing. A surface manifestation may comprise a cutout with a patch, or a folded over portion of the intermediate, retaining the card with the intermediate during processing. Alternatively, first and second thinned portions of the sheet of paper, disposed on opposite sides of a fold line so as to cooperate and hold the card when the sheet is folded about the fold line, may be provided, the thinned portions provided by embossing, for example. The card typically has a thickness substantially equal to or less than that of the intermediate; for example, the card may have a thickness of about 7 mil, while the sheet of paper forming the intermediate is 38 pound ledger paper, which also has a thickness of about 7 mil.

Title: Composition et procede de revetement par conversion a phosphate
Inventor: BOULOS MERVET S
IPC: C23C22/44
Filed: 1997-11-04
Abstract: L'invention concerne une combinaison aqueuse liquide de fluorure, d'acide citrique et/ou de ses sels, d'ions phosphate, d'une source d'hydroxylamine, d'un agent oxydant choisi parmi des composés organiques nitro-aromatiques hydrosolubles, de molybdates et de tungstates simples ou complexes. Cette combinaison permet d'obtenir des revêtements protecteurs par conversion à phosphate de bonne qualité pour des surfaces métalliques en fer, zinc, en aluminium, en magnésium et en alliage de magnésium, sans besoin de cations métalliques bivalents ou à valence supérieure, tels que ceux qui sont généralement utilisés pour produire des revêtements par conversion à phosphate de bonne qualité. Ces combinaisons renfermant de l'acide citrique produisent moins de résidu que d'autres combinaisons similaires, dans lesquelles l'acide gluconique est utilisé à la place de l'acide citrique. Si la combinaison comprend des tensioactifs adéquats, aucun nettoyage chimique préalable du métal destiné à être revêtu n'est nécessaire pour obtenir un résultat satisfaisant.

Title: Conveyor system
Inventor: MURPHY PATRICK M
IPC: B62D65/18
Filed: 1999-05-13
Abstract: A conveyor system having an infeed conveyor section, an outfeed conveyor section, and a working conveyor section positioned in between and in line with the infeed and outfeed conveyor sections. The working conveyor section includes a base and a frame which is movably mounted relative to the base between a lower position and a raised position. In order to move the frame between its lower and raised position, a driver is rotatably mounted about a substantially horizontal axis to the base while an elongated drive link has one end pivotally connected to the frame and its other end pivotally connected to the driver at a position radially spaced from its axis. A drive mechanism selectively pivots the driver between first and second rotational positions which are spaced substantially 180 degrees from each other. In doing so, the coaction between the driver and the drive link moves the frame between its raised and lowered position.

Title: Automatic inspection of print quality using an elastic model
Inventor: STRINGA LUIGI
IPC: B41J29/46
Filed: 1999-08-25
Abstract: The invention relates to a process for producing by electronic means a model for automatically inspecting the print quality on deformable objects. The model is firstly produced by capturing with an electronic camera (CCD for example) the images of a set of sheets whose print quality is regarded as acceptable; the images are stored so as to produce a first reference image, together with the relevant densitometric tolerance limits. This reference image is thereafter divided into a multitude of sub-images by superimposing a grid with very small mesh cells. During inspection, the distances between the nodes of the grid are measured on the image to be inspected: this therefore produces an elastic modification of the model, which is such as to make the distances between the nodes the same as in the image to be inspected. The image to be inspected is thus verified with respect to the modified reference (model) by using any of the standard inspection techniques.
