Patent CA-2234405-C (CA)
Title: A method for providing user global object name space in a multi-user operating system
Inventor: IACOBUCCI EDWARD E
IPC: G06F9/46
Filed: 1996-10-04
Granted: 2002-07-23
Abstract: A method, suitable for use in client/server system, which allows multiple copies of a single-user application to run simultaneously in a multi-user operating system without modification of the single-user program, by modifyi ng existing operating system methods used for object name creation, lookup, and  deletion. The method creates a user global context by labeling each instance  of the single-user application with a user identifier (name) that defines a single-user name space in which each labeled object is only available to the  named user. In addition, the single-user server process is allowed to impersonate the client for allowing the server to access the named resources  of the single-user name space. A coexisting system global context is also created by marking system global named resources.

Title: Thermal plasma reactor and wastewater treatment method
Inventor: KIMMERLE FRANK M
IPC: C02F1/46
Filed: 1996-12-20
Granted: 2005-04-19
Abstract: The invention relates to a reactor for the treatment of wastewater solutions containing cyanide and other dissolved organic material, having an elongated tube having an entrance (28) and an exit (32), and an energy source (22) for the tube, preferably positioned adjacent the exit. The energy source generates intense energy such that a cyanide/organic material-containing solution can be treated by passing it through the tube to expose it to said energy so that the solution absorbs sufficient energy from the energy source to degrade the cyanide and/or dissolved organic material contained therein. The source of intense energy is preferably a plasma, e.g. a plasma generated by a plasma torch or a DC electric arc. The invention also relates to a process o f treatment of such a wastewater solution by passing it through such a reactor.

Abstract: Monofilaments of a yarn to be coated with electroless nickel are pretreated with an acid and a surfactant to render the monofilament surfaces water wettable and not substantially mechanically degraded. The pretreated yarns is passed through an electroless nickel coating bath under little or no tension so that the electroless nickel can coat all of the monofilament surfaces substantially uniformly. The nickel coated yam then can be coated with electrolytic metal such as copper in an electrolytic metal plating step, as desired.

Title: A container closure with a frangible seal and a connector for a fluid transfer device
Inventor: VERLEE DONALD
IPC: A61J1/20
Filed: 1998-02-26
Granted: 2008-01-29
Abstract: A closure is provided for mounting across the mouth of a container and through which liquid can be withdrawn with a fluid transfer device having a male member. The closure includes a body for being disposed on the container across the container mouth.  The body defines a passage with an exterior opening for matingly receiving the male member of the fluid transfer device. A  frangible seal initially extends across the passage in the body to occlude the passage.  The seal is broken when it is engaged by the male member of the fluid transfer device, thereby establishing fluid communication between the fluid transfer device and the interior of the container.

Abstract: An assembly technique for closing a movable socket (10) without the need to deform or displace any portion of the socket housing (12), thereby allowing for the use of fully hardened socket housing materials. The internal components of the movable socket are installed within the housing through an opening (16), and a conical cover-plate (66) is positioned over the components, within the opening. An assembly tool (100) configured to exert pressure on the conical cover-plate is brought into engagement with the plate, and a downward load is applied, expanding the plate to seat within a circumferential groove (22) in the housing. The assembly tool includes a specifically contoured face (109) which alters the angle at which pressure is exerted against the expanding conical cover-plate as the plate deforms to a generally planar configuration, closing the opening in the housing. Once expanded, the cover-plate seats within the groove formed in the interior surface of the housing, thereby securing the internal components within the housing.

Title: Triterpene saponin analogs having adjuvant and immunostimulatory activity
Inventor: MARCIANI DANTE J
IPC: A61K47/48
Filed: 1998-05-20
Granted: 2008-03-11
Abstract: The present invention is directed to novel chemical compounds in which a lipophilic moiety such as a lipid, fatty acid, polyethylene glycol or terpene is covalently attached to a non-acylated or desacylated triterpene saponin via a carboxyl group present on the 3-O-glucuronic acid of the triterpene saponin. The attachment of a lipophile moiety to the 3-O-glucuronic acid of a saponin such as Quillaja desacylsaponin, lucyoside P, or saponin from Gypsophila, Saponaria and Acanthophyllum enhances their adjuvant effects on humoral and cell mediated immunity. Additionally, the attachment of a lipophile moiety to the 3-O-glucuronic acid residue of non- or des-acylsaponin yields a saponin analog that is easier to purify, less toxic , chemically more stable, and possesses equal or better adjuvant properties than the original saponin.

Abstract: A method and an instrument for a continuous non-invasive detection of an analyte, (e.g., glucose) concentration in a human body tissue such as blood, is disclosed. The instrument remote sensor assembly (7) mounted in subject's ear canal continuously measures analyte concentration by detecting the infrared radiation naturally emitted by a human body. It uses an infrared detector (7) with a combination of adequate filters (6) such as, for example, a negative correlation filter or narrow band filters or other detector filter assemblies. The method and instrument is based on the discovery that natural infrared emission from the human body, especially from the tympanic membrane (1), is modulated by the state of the emitting tissue.      Spectral emissivity of human infrared radiation from the tympanic membrane (1) consists of spectral information of the tissue, (e.g., blood) analyte, (e.g., glucose).      This can be directly correlated with the blood analyte concentration, for example, the blood glucose concentration.

Title: System and method for imaging test answer sheets having open-ended questions
Inventor: GONZALEZ JOSE A
IPC: G06K17/00
Filed: 1998-07-13
Granted: 2003-10-14
Abstract: An imaging system includes two sets of cameras: a first set for capturing optical mark or optical character recognition data and a second set for capturing visual images. Full visual images of pages containing answers to open-ended questions are retained and are retrievable by a reader such that an area of interest wherein the answer is expected is displayed, but the remaining area is also available for viewing. The system permits the alignme nt of a page based upon edge detection if the page contains only an open-ended answer, obviating the need for timing tracks. Hardware and software elements cooperate to store the image temporarily in a server having a response time commensurate with the scanner. The image is then processed with the use of high-performance index imaging for optical storage and retrieval, and then routed to a long-term storage device.

Abstract: An IR transceiver having a receiver chain with an isolated analog output, provides a transmission gate and unity gain buffer interposed between the amplifier output and an analog output pad. The transmission gate behaves as a switch, passing the analog output signal to the analog output pad only when an analog output is required. The unity gain buffer has a high input resistance, a low input capacitance, a unit gain and a low output impedance, so that the load of a DSP device or measuring instrument on the analog output pad is isolated and does not affect the performance of the receiver chain. Since the transfer rates of the transmission gate and the buffer are each a unity, the analog output pad provides a high fidelity analog output signal to the output buffer.
