Patent CA-2113733-C (CA)
Inventor: FOOS JOSEPH S
IPC: G01N27/48
Filed: 1994-01-19
Granted: 2009-02-24
Abstract: A planar, solid-state electrochemical oxygen sensor having a substrate, conductive strips deposited on the substrate, and a dielectric layer insulating portions of the conductive strips except those portions which define a working electrode and at least one second electrode. The working electrode may be defined by an open printed region of the dielectric, or by a needle-punched or laser-burned hole or opening in the dielectric which exposes a small region of one of the conductive strips. A solid electrolyte contacting the electrodes is covered by a semipermeable membrane which may comprise an acrylonitrile butadiene copolymer or an acrylate-based copolymer. A sample chamber is defined by the membrane, a cover member, and a gasket therebetween, and has a volume of from about 1 to about 2 ml. The gasket is formulated from the highly cross-linked polymerization product of epichlorohydrin. All sensor components are selected such that a sensor operable for at least 2 days under normal conditions is produced.

Title: Improved arrangement of source and receiver lines for three dimensional seismic data acquisition
Inventor: CORDSEN ANDREAS
IPC: G01V1/20
Filed: 1994-02-01
Granted: 1999-05-25
Abstract: The invention involves providing a plurality of substantially parallel and equally spaced source lines each of which are formed by a plurality of equally spaced seismic energy sources. A plurality of substantially parallel and equally spaced receiver lines are also provided each formed by a plurality of equally spaced seismic energy receivers. The source and receiver lines are overlaid in a transverse crossing manner forming a rectangular grid so that the particular spacing or relative offset between a source and a receiver is repeated only at every second or greater number of crossings. Preferably, the relative offset is substantially zero so that a source and a receiver are substantially coincident at only every second or greater number of crossings. For each seismic disturbance, an array of common mid-point seismic reflections ("CMP's") is produced. Each CMP forms the center of one of multiple sub-bins which together form a standard bin. Stated otherwise, by slightly varying the source, receiver and line intervals so that the particular relative offset between receiver and sources is repeated, but only at every second or greater crossing, the number of CMP's per bin has been multiplied. During processing of the seismic survey results, adjacent sub-bins can be incrementally combined or trimmed to adjust the standard bin to a larger or smaller size, thereby permitting an explorationist to optimize between increased fold or more detailed resolution respectively.

Title: An arrangement for painting an extended object moving continuously in its longitudinal direction
Inventor: LINDBLAD ANDERS
IPC: B05B13/02
Filed: 1992-09-09
Granted: 2004-08-03
Abstract: To obtain paint on all sides of a strip, painting must be performed in two stages since the strip must rest on a surface while being painted. This is avoided if moving strips are guided in a manner allowing them to be free from mechanical support from the start of painting until they have passed a drying unit (11), after which they can rest on a support surface without the paint being damaged.

Granted: 1998-05-26
Abstract: A housing (10) for use with an electrical heater (H) mounted on the sidewall (S) of a container (C) for heating a fluid (L) in the container.  A heating element (R) is installed in a fitting (F), and the housing facilitates connection of electrical conductors (E) to the heater regardless of its location.  A base (12) has an opening in which the fitting is received.  The base is positioned against the sidewall when the heater is installed.  A cover (36) is sized to fit over the base and attaches thereto.  The base has an opening (22) therein through which the electrical conductor is routed for connection to an outer end of the heating element.  A ring (28) is used to attach the heater to the base.  The baseplate captures the one end of the fitting so the base is freely rotatable with respect thereto.  Rotation of the base positions the cover so the conduit opening is readily accessible to an installer thereby to facilitate connection of the conduit to the heating element regardless of the heater location.

Title: Method of managing memory allocation in a printing system
Inventor: AMBALAVANAR SAMUEL D
IPC: G06F12/02
Filed: 1995-07-13
Granted: 1999-06-01
Abstract: A method of managing memory allocation in a printing system including the steps of creating a plurality of blocks and designating each block with an identifier. In response to a request from a client, a first set ofidentifiers, corresponding with a first set of blocks, is placed into a databaseby a resource manager. The client then accesses the database and, by reference to the first set of identifiers, begins filling up the first set of blocks with image data. As each block is filled, the client transmits an interrupt signal to a controller. After a predesignated one of the first set of blocks has been filled, the controller causes the resource manager to place a second set of identifiers in the database so that the client can access the second set of identifiers as soon as it has completed filling the first set of blocks.

Abstract: Carrier stock for beverage cans or other cans of a type having a chime at an upper end and having a frusto-conical wall below the chime is formed from a single sheet of resilient polymeric material, such as low density polyethylene, with band segments defining can-receiving apertures, with webs extending generally transversely and separating the can-receiving apertures in each longitudinal row, and with finger-gripping straps arranged in pairs and configured such that each strap of each pair extends generally transversely between two of the inner band segments and is curved inwardly toward the other strap of the same pair.  Each finger-gripping strap has two legs, each being connected not only with an inner band segment but also with a connecting web, which extends therefrom, which extends generally along an inner band segment, and which connects such leg with a separating web.  At each leg, connecting web, and inner band segment, the carrier stock may have a dividing slit or a dividing aperture.  In a package comprising the carrier and associated cans, some of the lifting forces imparted to the finger-gripping straps are distributed to the separating webs through the connecting webs, so as to reduce tendencies of the carrier to peel off the cans where the finger-gripping straps are connected.

Abstract: A single bed thermal oxidizer for oxidizing a contaminate in a gas (air) stream has a plenum above the bed containing burners for gaseous fuel and means for injecting excess air. The burners are activated to initially heat the adjacent top bed portion. The burners are then turned off and a mixture of gaseous fuel and air is passed down into and through the bed which oxidizes the gaseous fuel and transfers the hot portion of the bed downward to preheat the central region of the bed. At that point, the gaseous fuel is terminated and the contaminated gas stream is introduced into the preheated bed for oxidation of the contaminate .

Abstract: Cette invention concerne une technique permettant de préserver l'intégrité de la partie centrale absorbante d'un article jetable. Dans cette invention on utilise des colonnes qui dépassent de la feuille de support d'un article jetable absorbant ou d'un sous-vêtement et qui se projettent dans la masse fibreuse d'une partie centrale absorbante déposée sur une feuille de support imperméable aux liquides. Une feuille supérieure, perméable aux liquides, recouvre la partie centrale formée de matière fibreuse et entoure la partie centrale absorbante et la feuille de support. Cette feuille supérieure peut également comporter des colonnes similaires. Ces colonnes servent à réduire le déplacement des fibres dans la partie absorbante et, plus spécifiquement, à renforcer et conserver l'intégrité de ladite partie centrale absorbante dès lors qu'elle est humide et/ou soumise à des contraintes. Ces colonnes renforcent la résistance de la partie centrale absorbante et réduisent la décomposition qu'elle peut subir.
