Patent CA-2379576-A1 (CA)
Inventor: KAY CHRISTOPHER JAMES
IPC: G01B5/02
Filed: 2000-07-13
Abstract: During use, a wheel of a railway vehicle may become out of round, which will  be detrimental to both the vehicle suspension and the railway track. The sha pe of such a wheel may be monitored to detect any such out of roundness, while the wheel is rolling, by measuring how far the flange of the wheel projects below the upper surface of the rail. This may be achieved by mounting a rigi d bar (24) alongside the rail (10), the bar (24) being supported resiliently s o as to be depressed by a flange of a wheel (40), and by measuring the vertica l displacement of the bar. The bar (24) may be supported by a plurality of fla t leaf springs (26), which are inclined to the horizontal at for example 30~. This ensures that the bar (24) remains substantially parallel to the top surface of the rail (10) when depressed by the flange of a wheel (40).</SDOA B>

Title: Solutions de chlorite chimiquement stables, destinees au traitement du cancer et d'autres maladies
Inventor: KODELJA VITAM
IPC: A61K33/20
Filed: 2000-08-18
Abstract: L'invention concerne des méthodes d'utilisation d'une matrice de chlorite stabilisé, destinée à moduler des réponses immunes et à traiter le cancer. Cette matrice de chlorite stabilisé, lorsqu'on l'administre à un mammifère nécessitant un tel traitement, peut activer des cellules immunes de manière similaire à l'interféron gamma, mais elle ne produit pas de cytokines inflammatoires ou associées au stress, comme le facteur de nécrose tumorale alpha. Cette matrice de chlorite stabilisé régule également en amont l'expression de la protéine DCC dans des macrophages, protéine dont l'expression est associée à la transformation néoplasique. En activant les macrophages, la matrice de chlorite stabilisé est donc utile en tant qu'agent immunomodulateur et dans le traitement du cancer.

Patent CA-2390529-A1 (CA)
Title: Methods and apparatus for coordinating channel access to shared parallel data channels
Inventor: WHITEHILL ERIC A
IPC: H04L12/407
Filed: 2000-11-03
Abstract: A network of nodes communicates using plural, shared parallel data channels and a separate reservation channel. Access to the data channels is coordinat ed among the nodes by communicating message requests and corresponding replies on the reservation channel. In addition to a primary transmitter/receiver (e.g. , a modem), each node includes a secondary receiver that permits each node to continuously monitor the reservation channel. When not engaged in a message transfer on one of the data channels, the primary receiver monitors the reservation channel. If the primary becomes engaged in a message transfer, t he secondary receiver is activated and monitors the reservation channel. Use of  the secondary receiver avoids loss of channel access information resulting from use of a single receiver for both the reservation and data transfer mechanisms. By transmitting requests for channel access on the reservation channel and continuously monitoring the reservation channel, message collisions are dramatically reduced.

Title: A system, method, and computer program for managing storage and distribution of money tills
Inventor: CARTER ODIE KENNETH
IPC: G07F7/02
Filed: 2000-12-06
Abstract: A computer-controlled automated management system (20) for monitoring and controlling distribution and storage of money tills, and linking tracking of employee productivity to time in receipt of a till. The system (20) comprises a cabinet (22), a control panel (28), and a personal computer (30). The cabinet (22) is mounted through a wall to provide an interface having a front side accessible from a first area and rear side accessible from a second area, such as, for example, a cash room. The control panel (28) is mounted next to the cabinet on the front side of the wall. The interior cabinet space is divided into a plurality of till compartments (24), with each compartment (24) being selectively accessible from both the front and rear of the cabinet (22).  Tills are loaded and removed from the rear by cash room personnel and from the front by cashiers and other employees. In order to remove a till from the front of the cabinet (22), the employee must identify him or herself using a keypad (62) or other device provided at the control panel (28), which, in turn, communicates the information to the computer (30). The computer (30) receives the identification information and matches it to employee and authorization information stored in a database. The computer (30) is then able to match the particular employee with a particular till in a particular compartment (24). The computer (30) records the time and other relevant data and opens the appropriate cabinet door (40) to allow the employee to take the till. When the employee returns the till, a similar process occurs. The system (20) is further operable to anticipate, based upon work schedules, needed till types or amounts; compile and maintain useful associated records, including employee productivity (i.e., time in possession of a till); and link to and integrate with other systems to further improve efficiency.
