Patent CA-2315014-A1 (CA)
Inventor: BINGHAM DENNIS N
IPC: F25J3/00
Filed: 1998-12-16
Abstract: A process for the separation and liquefaction of component gasses from a pressurized mix gas stream is disclosed. The process involves cooling the pressuized mixed gas stream in a heat exchanger so as to condense one or more of the gas components having the highest condensation point; separating the condensed components from the remaining mixed gas stream in a gas-liquid separator, cooling the separated condensed component stream by passing it through an expander, and passing the cooled component stream back through the heat exchanger such that the cooled component stream functions as the refrigerant for the heat exchanger. The cycle is then repeated for the remaining mixed gas stream so as to draw off the next component gas and further cool the remaining mixed gas stream. The process continues until all of the component gases are separated from the desired gas stream. The final gas stream is then passed through a final heat exchanger and expander. The expander decreases the pressure on the gas stream, thereby cooling the stream and causing a portion of the gas stream to liquify within a tank. The portion of the gas which is not liquified is passed back through each of the heat exchangers where it functions as a refrigerant.

Abstract: A diaphragm type flush valve for use with toilet devices such as urinals and water closets includes a body having an inlet and an outlet, a valve seat between the inlet and outlet, and a valve movable to a closing position on the valve seat to stop the flow between the inlet and outlet. The valve member includes a diaphragm peripherally attached to the body and a disc positioned on top of the diaphragm. There is a guide extending downwardly from the diaphragm. The disc is attached to the guide and functions to secure the diaphragm, disc and guide into the valve member. The disc includes a rigid body and a seal member, with the seal member having a portion on an upper surface of the disc for sealing contact with a relief valve, and a portion on a lower surface of the disc for contact with the diaphragm. The disc is attached to the guide through a one-way clutch which permits relative rotation of the disc and guide in one direction during assembly, and prevents relative rotation in the opposite direction after assembly.

Title: Hierarchical data network address resolution
Inventor: MARTIN CLIFFORD E
IPC: G06F17/30
Filed: 2000-12-12
Abstract: A network server stores database tables for use in resolving labels into network addresses as requested by a remote browser client. Each user has an associated address-table which stores user defined labels associated with network addresses. Users may access other user's address-tables if such other users grant authority to do so. Each user defines the address-tables to be searched, along with a search order, to be used when the user requests that a label be resolved into a network address. During address resolution, the server will resolve a received label into the network address associated with the label as defined by the first accessed address-table which contains the label. The search order as defined by the user may be overridden for a particular address resolution request by an appropriate user command. In various embodiment, the network addresses may be WWW addresses and electronic mail addresses.

Title: Method and system for retrieving relevant documents from a database
Inventor: KAUFMAN ILIA
IPC: G06F17/30
Filed: 1999-06-07
Abstract: A method for processing a search query uses the results of a search performed on a high quality, controlled database to assess the relevance of documents retrieved from a search of an uncontrolled public database having documents of highly variable quality. The method includes the steps of parsing the search query and then searching the authoritative database to generate authoritative database results. The search query is also used to search the public database, thereby generating public database results. The quality or relevance of the public database results are then quantified on the basis of the authoritative database results, thereby generating a quality index. The results from both the authoritative and the public databases are then ranked on the basis of this quality index.

Title: Optical probe having and methods for uniform light irradiation and/or light collection over a volume
Inventor: HILDWEIN ROGER L
IPC: A61B1/307
Filed: 1999-07-01
Abstract: A variety of optical probes and optical methods have utility in the examination of various materials, especially materials in the interior of cavities having restricted access through orifices or passageways. An optical probe useful, for example, in examining the epithelia and other tissues of anatomical structures within the body cavities and tubular organs and viscera of mammals is elongated and includes an optical window (240, 302, 1002), a light source (222, 312, 314, 510, 520, 1020, 1200, 1400, 1700), a spatial mixer (224, 304, 2004, 2104, 2204, 2304), and a light collector (210, 320, 720, 1120). The light from the light source is mixed in the spatial mixer, thereby removing any reflected images and irradiation artifacts to achieving uniform diffuse light in the vicinity of the optical window. The light collector receives light from the target through the spatial mixer, but the field of view of the light collector excludes any residual reflections and fluorescence from the spatial mixer. The optical probe may be made of two sections, a reusable section and a disposable section. Disposables (910, 2000, 2100, 2200, 2300) suitable for use with the reusable probe section (900) are elongated and contain a spatial mixing section utilizing an inside surface suitable for the spatial mixing of light, an elongated section extending from the spatial mixing section for mounting the disposable onto the reusable probe section, and a protective window or lens for sealing the reusable probe section from the target. Disposables may be constructed from various low cost materials.

Title: Supervisory control plane over wavelength routed networks
Inventor: FAN YANHE
IPC: H04B10/20

Abstract: A dedicated IP-based wavelength routing/signaling control plane for optically switched network, is provided. The IP-based control plane is an out-band routing/signaling mechanism and does not require optical-electrical-optical (OEO) conversion. The control plane can accommodate the various network topologies of the data plane and if one of the supervisory, or control channel fails, the IP-based control plane can re-route the traffic to destination.      Using non-broadcasting addressable protocols the control plane selects a different path to re-direct the control information without declaring the whole communications trail down and without affecting the client traffic over the data path.
