Title: A method and system for changing rating data via internet or modem in a carrier management system
Inventor: RAUH EDWARD
IPC: G06F17/30
Filed: 1998-09-25
Abstract: The invention is a method and system of updating a set of data objects within a Data Access System (DAS). The method begins by initiating a communication link between a client and a host data processing system. Once a communications link is established, a set of object tables is uploaded from the client data processing system to the host. The object tables are read at the host; and, a determination is made as to which data objects in the set of object tables are to be updated. It is also determined which data objects in the set of object tables is to be simply maintained. A new set of object tables is then constructed at the host data processing system and transmitted to the client data processing system. Upon receipt of the new file tables, the client system performs the task of verifying accurate receipt of the new set of object tables prior to restarting the client data processing system. The verification step includes saving at the host, a first data map of the new set of object tables as a record of which objects were transmitted. The new set of object tables is then received and saved within a memory of the client data processing system before retransmitting the new set of object tables as a second data map back to the host from the client. The second data map is then compared with the first data map to form a comparison, and if the first data map and the second data map do not match, then the verification is nulled.

Patent CA-2258379-A1 (CA)
Inventor: WILLIAMSON JIMMIE R
IPC: E21B7/08
Filed: 1999-01-07
Abstract: Improved apparatus and methods for deploying tools in multilateral wells are disclosed. Certain ones of the apparatus and methods include a downhole tool centralizer assembly for coupling to a downhole tool. The centralizer assembly has a tubular centralizer retainer with an external surface and an annular recess on the external surface. An annular spring member is disposed within the annular recess, and the annular spring member has an outer diameter greater than a predetermined inner diameter of a bushing disposed proximate a junction between a main wellbore and a lateral wellbore. Other ones of the apparatus and methods include a downhole tool having a substantially identical tubular centralizer retainer and annular spring member. As the centralizer assembly, or the downhole tool, enters the bushing, the annular spring member elastically deforms so that the outer diameter of the spring member becomes substantially equal to the predetermined inner diameter of the bushing. Such elastic deformation prevents the centralizer assembly, or the downhole tool, from accidentally entering the lateral wellbore.

Title: Adjustable soap dispenser
Inventor: CHINKS MATTIE
IPC: A47K5/12
Filed: 1999-02-18
Abstract: This invention relates to an improved liquid soap dispenser of the type ones which are commonly located in public washrooms and the like. These kind of soap dispensers include a frame, a manually operable pump mounted on the frame and a reservoir operatively connected to the pump for supplying soap to be dispensed. The soap is generally dispensed when a tube, connected to the reservoir, is squeezed. The current invention provides simple and efficient ways for controlling the quantity of soap dispensed from such liquid soap dispenser. As such, the amount of pressure provided to the tube is varied, thereby varying the amount of soap dispensed. Preferably, the pump includes a handle and a wall portion facing each other on opposite sides of the tube. The wall member is pivotable about a pivot point, so that by increasing the angle between the wall member and the tube, the handle does not compress the tube as much and thus less soap is dispensed.

Patent CA-2268548-A1 (CA)
Inventor: SOLOMON ROBERT C
IPC: G06F3/06
Filed: 1997-10-08
Abstract: A high performance data path for performing XOR on the fly. A first memory is connected to a first bus and a second memory is connected to a second bus selectively coupled to the first bus. Logic for performing an XOR can be switched into connection with the first and second bus for XORing data in a buffer with the data passed from one of the memories to the other memory. The result is replaced into the buffer to permit successive XORing. When reading from an interrelated group of disks such as a RAID 3 group, the data path permits an N-1 and go mode in which a read does not wait for data from the last disk to retrieve its data sector. If the last disk contains data (as opposed to parity) the data is obtained from the XORed data in the XOR buffer of the high performance data path. For writing data, the XOR on the fly generates the parity sector for writing at the completion of a write to an interrelated group of disks.

Title: Transfer printing process
Inventor: BOATE ALAN
IPC: B41M3/14
Filed: 1999-06-25
Abstract: A transfer printing process is provided which both uses conventional equipment, and which can be used to add second level printing to an existing document such as a passport. All of the information to be applied in a second level printing procedure to a base sheet is assembled as a complete image. The image is printed in reverse, as a stable mirror image, onto the coated surface of a release paper by a conventional laser printer. The release paper carrying the reversed image and the base sheet are then placed into a heated press, with the image adjacent the base sheet. By the use of heat and pressure the image is transferred from the release paper onto the base sheet. The release paper is then removed, leaving the second level printed image on the base sheet.
