Patent CA-2252087-A1 (CA)
Inventor: WLASCHIN SCOTT
IPC: G06F17/30
Filed: 1997-04-10
Abstract: A distributed storage system provides a method and apparatus for storing, retrieving, and sharing data items across multiple physical storage devices that may not always be connected with one another. The distributed storage system of the present invention comprises one or more 'partitions' on distinct storage devices, with each partition comprising of a group of associated data files. Partitions can be of various types. Journal partitions may be written to by a user and contain the user's updates to shared files. In the preferred embodiment, journal partitions reside on a storage device associated with a client computer in a client-server architecture. Other types of partitions, library and archive partitions, may reside on storage devices associated with a server computer in a client-server architecture. The files on the journal partitions of the various clients may, at various times, be merged into a consolidation file or a file resident within the library partition. If two or more clients attempt to update or alter data related to the same file, the system resolves the conflict between the clients to determine which updates, if any, should be stored in the library partition. The merge operation may occur at various time intervals or be event driven. The archive partition stores files from the library partition.

Patent CA-2254317-A1 (CA)
Inventor: BLAIR ROBERT JAMES
IPC: B60B7/16
Filed: 1998-12-04
Abstract: The already patented (USA) Wheel Clamp was designed as a security device to prevent the theft of vehicles and trailers. When it is installed on the wheel of the vehicle, it immobilizes the vehicle so that it cannot be stolen. It clamps to the inner and outer rim of the wheel and at the same time covers one wheel nut, so that the wheel cannot be removed by removing the wheel nuts. It does not however prevent the removal of the center hub nut (sometimes called the axle nut). Therefore, if a thief were to remove the center hub nut, he could remove the entire wheel and Clamp from the axle, and replace it with a substitute tire. This would allow the vehicle or trailer to be stolen The purpose of the Wheel Hub Cover Accessory Kit is to cover the center hub nut, mentioned above, so that it cannot be undone and the wheel cannot be removed in that manner. The Wheel Hub Cover is an accessory to the Wheel Clamp and must be used in conjunction with the Clamp, in order for it to work.   Its use is especially important in the case of vehicle or trailer with a tandem axle, (i.e. 4 wheels with 2 axles on the rear). Without the use of the Wheel Hub Cover Accessory Kit, a thief could potentially remove the clamped wheel from the axle and drive away on the three remaining wheels without the need for a replacement tire.

Title: Method and apparatus for pulping with controlled heating to improve delignification and pulp strength
Inventor: PROUGH J ROBERT
IPC: D21C1/02
Filed: 1997-09-17
Abstract: Low temperature steaming and slurrying of wood chips results in significant improvement in treatment, the chips being maintained at a temperature below 110 °C (more desirably at about 105 °C or less, and most desirably at about 100 °C or less) until actually heated to cooking temperature. Steaming may be accomplished utilizing a vertical chip bin with one dimensional convergence and side relief or a horizontal steaming vessel, the steaming device connected to a high pressure feeder. A pump having an NPSHR less than the NPSHA may be used for drawing slurry into the high pressure feeder from the steaming device, or a pump may be disposed between the steaming device and the high pressure feeder for forcing slurry into the high pressure feeder through a conduit including a radiused elbow. The steaming is practiced at a pressure of 5 psig or less, preferably substantially atmospheric steaming is practiced. The pulp produced typically has strength properties at least about 10% greater than the pulp produced from material where it is steamed and slurried at temperatures in excess of 110 °C.

Title: Audio-based wide area information system
Inventor: NAQVI SHAMIN A
IPC: H04H20/00
Filed: 1997-12-16
Abstract: A wide area information system includes a client and at least one server on which audio data is stored. Audio data is selectively transferred to the client from the server by at least occasionally establishing a transfer connection between the server and the client. The transfer of audio data is controlled by user-selected commands and inputs that are entered via an input interface provided on the client. These commands and inputs are also transferred to the server via the at least occasionally established transfer connection between the client and the server. The audio data on the server is organized in page units that are cross-linked by way of hyperaudio links. The page units are characteristically searchable with the use of cyclically repeating directory pages of audible directory information. A data protocol is defined for enabling such an audio-based system.

Filed: 1997-12-22
Abstract: A method for monitoring changes in the level of an osmotically active component, such as for instance glucose, or in healthy humans, such as athletes for monitoring the level of lactic acid in the muscles is described.  The key feature of the method is that the osmotic movement back and forth over a membrane is used to activate a sensing device, whereby the physical changes that take place in the fluid may be recorded by a receiver situated outside the body. A device for carrying out said method is likewise described.
Patent CA-2274238-A1 (CA)
Title: Gate assembly for a double disk gate valve
Inventor: KENNEDY PAUL G
IPC: F16K3/18
Filed: 1999-06-10
Abstract: A gate assembly for a double disk gate valve having two closure disks with a resilient material between. The resilient material and closure disks are enveloped in an outer harder coating. Closing the gate valve brings the disks into initial sealing contact with the bottom of the valve seat. Applying pressure to the gate valve after contact is made between the gate assembly and the valve seat causes the resilient central member to exert pressure against the closure disks, thus pressing the outer coating of the gate assembly against the sidewalls of the valve seat. This action creates a better sealing engagement with the seat surface to exclude flow. Wear on the gate assembly is significantly reduced since the gate assembly does not make contact with the sidewalls of the seat while being moved between an open position and a closed position.

Patent CA-2276917-A1 (CA)
Inventor: WRIGHT JOHN O
IPC: H01R13/627
Filed: 1999-07-06
Abstract: A connector latch is provided which includes a connector housing which extends through an engagement member. The engagement member is movable from one end of the connector housing to the other end. When moved to one end, the engagement member cams flexible latch arms of the connector housing towards the longitudinal axis thereof in a locked mode.      When moved to the opposite end, the flexible latch arms reslide away from such axis in an unlocked mode. An electrical connector which includes such a connector latch is also provided. In such an embodiment, when male and female contacts are properly engaged, movement of the engagement member in the locked mode causes protuberances which extend from the flexible latch arms to extend into a connector housing groove thereby preventing disconnection of the contacts.

Title: Beverage can cap
Inventor: SEPT CLAYTON
IPC: B65D41/18
Filed: 1999-06-30
Abstract: A reusable insulating cap is shown for preventing dirt, insects and other foreign objects from accessing the lid and interior of a beverage can. A number of internal vent grooves are located about the cap to allow for the pressure of any carbonation or fermentation to escape to the ambient. The cap is made of a uniform, foam-like, resilient material to conform to varying sizes and shapes of can tops, and to allow a user to easily remove the cap from the can by exerting a moderate prying force with one hand, while the other hand holds the can. The cap helps keep the top of the can cool after refrigeration and reduce heat transfer with the ambient. The cap is easy to clean and store, allows for the stacking of like capped cans, and is light weight and attractive.
