Patent CA-2274579-A1 (CA)
Title: Catalyst/wax separation device for slurry fischer-tropsch reactor
Inventor: BENHAM CHARLES B
IPC: C10G2/00
Filed: 1997-12-15
Abstract: Catalyst particles are separated from the wax in a Fisher-Tropsch reactor by feeding a portion of the reactor slurry to a dynamic settler which does not require any pump. As the slurry flows down a pipe in the center of the settler, the slurry flows into the surrounding annular region at the bottom of the settler. The heavier catalyst particles settle down and are removed as the slurry at the bottom of the settler is recycled back to the reactor. The wax rises up in the annular section and this clarified wax is removed by a wax outlet pipe. In an embodiment with an expanded diameter section above the Fisher-Tropsch reactor an additional dynamic settler can be placed inside this section. The Fischer-Tropsch catalyst can be regenerated by purging the catalyst with an inert gas for a period of time and by treating the catalyst with naphtha.
Patent CA-2279368-A1 (CA)
Inventor: NGUYEN VIET
IPC: H04Q3/00
Filed: 1998-01-15
Abstract: A protocol initialization message is generated (100) by an originating node of a communication network for transmission to each of its cooperating nodes in the network. This message identifies the communications protocols and capabilities (industry standardized and proprietary) supported by the originating node. Responsive to the protocol initialization message, cooperating nodes operate to update their data matrices (102) storing protocol and capability information for the originating node, and generate a protocol initialization response (104) for transmission back to the originating node.  This response identifies the communications protocols and capabilities (industry standardized and proprietary) supported by the cooperating node.  Responsive to the protocol initialization response, the originating node operates to update its data matrix (106) storing protocol and capability information for the cooperating nodes.
Patent CA-2282942-A1 (CA)
Title: Efficient authentication with key update
Inventor: BERENZWEIG ADAM L
IPC: H04L9/08
Filed: 1999-09-21
Abstract: A more efficient method for performing authentication is provided by using an authentication challenge transmitted to a terminal to provide the terminal with the information to calculate authentication and cipher key values. As a result, a separate communication is not required to provide the terminal with key values. A visiting authentication center obtains a random value R T, an authentication key value K A and a cipher key value K C from a home authentication center. The visiting authentication center then transmits the random number R  T to the terminal to update the terminal's authentication key and cipher key values, and to challenge the terminal as part of an authentication process. The terminal uses R T to calculate the authentication key value K A and the cipher key value K C, and to respond to the visiting authentication center's challenge. In addition, the authentication key value is used to verify the visiting network's response to the terminal's authentication challenge to the network.

Title: Method and apparatus for direct writing of semiconductor die using microcolumn array
Inventor: BERGLUND C NEIL
IPC: H01L21/027
Filed: 1999-03-19
Abstract: In electron beam lithography, a lithography system uses multiple microcolumns in an array to increase throughput for direct writing of semiconductor wafers. The mismatch between the microcolumn array and the semiconductor die periodicity is resolved by using only one microcolumn to scan each individual die. This is accomplished by assuring that the stage carrying the semiconductor wafer moves a total distance in each of the X and Y directions which is greater than the pitch between adjacent die. Hence each die is scanned by only a single microcolumn although at possibly different times during the total stage motion.

IPC: A61F2/06
Filed: 2000-03-31
Abstract: A stent is made flexible along its length. The stent initially starts as a metal sheet. It is rolled in its central region to a specified wall thickness. Thereafter, the stent is photochemically etched to produce the desired cell pattern of the design of the stent. Then, the stent is folded and the metal is joined to give rise to a stent with multiple wall thickness. For instance, larger wall thicknesses at the end of the stent versus smaller wall thicknesses at its center. Various other possible manufacturing methods are useful with respect to this stent. The stent can also be produced in an initial tube shape. The tube can be etched several times to get varying wall thickness.
