Patent CA-2485892-A1 (CA)
Inventor: GANTMAN ALEXANDER
IPC: H04L9/30
Filed: 2003-05-15
Abstract: A hand-held sonic token (12) can be used as a pseudorandom oracle for a requesting application, which can generate a challenge that is sent to the token (12). The user of the token (12) decides whether to allow the token (12) to function as an oracle, and if so, the user causes the token (12) to digitally sign the challenge and send it back to the requesting application (34), for use of the digitally signed challenge as an encryption key. After encryption the requesting application deletes the signed challenge, with subsequent decryption essentially following the encryption process.

Title: Dielectric barrier discharge lamp having a base
Inventor: KLING RAINER
IPC: H01J61/02
Filed: 2003-05-14
Abstract: An elongated dielectric barrier discharge lamp with outer and inner electrod es has a tube that is arranged on the lamp stand end of the discharge vessel an d that surrounds said lamp stand. Said tube serves to receive a seal in order to install the lamp in a process chamber in a gastight manner. Power supply of the outer electrodes is separated from the power supply for the inner electrodes coming out of the lamp stand by means of the above-mentioned tube . This makes it possible to prevent effectively parasitic discharges between t he power supplies which are applied at different potentials during operation al so in process chambers under negative pressure.

Title: Apparatus and method for handling messages that relate to a cell other than the currently operating cell in universal mobile telecommunications system user equipment
Inventor: FARNSWORTH ANDREW JOHN
IPC: H04M11/00
Filed: 2004-11-09
Abstract: Methods for handling of messages that relate to a cell other than the cell with which a user equipment (UE) device is currently communicating in a universal mobile telecommunication system (UMTS) network. The network does not forward to the UE device any messages which were generated for the user equipment device when communicating with a first cell after receiving a message indicating that the UE device has changed to communicate with a second cell. Alternatively, the UE device does not fully operate on a received message, the message being directed to a cell different from the cell with which the UE device is currently communicating. Or, the UE device delays changing to a new cell until a received message is acted upon. Or, alternatively, whenever a cell update message is to be sent from the UE device to the network, the message indicating a cell re-selection, the UE device carries out any steps required when a cell re-selection is performed.

Patent CA-2502346-A1 (CA)
Inventor: MILANI WALTER
IPC: A62C3/00
Filed: 2005-03-24
Abstract: A fire barrier component has an outer sleeve retaining and protecting a fire stop material therein which is preferably compressed. The outer sleeve when exposed to a fire condition partially fails and the fire stop material forms the fire stop barrier. The fire stop material if compressed expands and can cooperate with adjacent components to form an effective fire stop barrier. The firestop barrier component can be factory made and used in complete fire barrier systems, or the component can be used as part of a specific field application. The component may be sold in longer lengths and cut as required to meet a particular application.      Conventional saws work satisfactorily in cutting of the component while maintaining the performance of the component when exposed to a fire condition.

Title: Methods and dosage forms with modified layer geometry
Inventor: REN FEIYAN
IPC: A61K9/24
Filed: 2004-02-11
Abstract: Dosage forms and methods for providing a modulated release of cyclobenzaprine are provided. The sustained release dosage forms provide therapeutically effective average steady-state plasma cyclobenzaprine concentrations when administered once per day. The present invention pertains to methods of enhancing release rates by modifying the geometry of core layer interfaces through inversion of the traditional compression sequence in order to alter the mixing of layers during operation and by modifying the composition of core layers such that the viscosity of the hydrated delay layer remains higher than the viscosity of the hydrated drug layer during operation. The result is greater uniformity in the release rate from the core providing a more optimal ascending release rate and consistent performance.

Abstract: A method of hard-facing a steel casting is described in which a hard-facing, which comprises a weld alloy matrix and a hard particulate substance, is attached to the casting by welding. In some embodiments the matrix can be of a similar composition to the casting, and in other embodiments the hard particulates can be rounded and/or substantially spherical, or of a substantially even size. A method is also described for hardening and tempering a steel casting after attaching the hard-facing to the casting by welding.

In one embodiment the hard-faced casting is heat treated by heating to a temperature in excess of the austenitising temperature of the steel and then cooled by quenching in an aqueous solution, followed by tempering. In one embodiment the steel casting is tempered at a temperature in the range about 550° C. to about 700° C. prior to hard-facing the casting.
