Patent CA-2246506-A1 (CA)
Title: Transmission control method in a collision-based access system
Inventor: TAKETSUGU MASANORI
IPC: H04W4/04
Filed: 1998-09-03
Abstract: A transmission control method is provided which can improve a decrease in throughput when collision occurs during the use of a collision-based access system. In response to forward link message DA11(I,0) from a radio base station 10, a terminal 11 transmits a packet signal D11(0) while a terminal 12 transmits a packet signal D12(0). When the packet signals collide head-on, the radio base station 10 does not receive them but transmits forward link message D12(I,0). When the terminals 11 and 12 receive the forward link message, they judge that the packet signals transmitted by themselves have collided head-on and then transfers to a back-off state in which random time transmission is sustained. When forward link message DA13(I,0) is received from the radio base station 10, the terminal 12 restored from the back-off state retransmits the packet signal D12(0). Meanwhile, the terminal 11 is changed to a back-off state when receiving forward link message DA15(P,11) from the radio base station 10. The terminal 11 does not originally transmit a packet signal but retransmits the packet signal D11(0) because transmission request from the radio base station.

Patent CA-2255990-A1 (CA)
Title: Method and system for voice call completion using information retrieved from an open application on a computing machine
Inventor: FRANK ALAN STUART
IPC: H04M7/00
Filed: 1998-12-04
Abstract: A method and apparatus for call completion using information extracted from an active application on a computing machine is described. Call initiation may be accomplished using a "warm-line" feature in which a default number is dialled after a predetermined time of an off-hook condition of a voice terminal, if no digits are dialled after the voice terminal is taken off-hook. The number dialled is a number used to connect the telephone set to computer-Controlled Telephony Integration hardware (CTI). On receipt of the call, the CTI hardware extracts Automatic Number Identification (ANI) information to determine the number of the calling party and verifies that the calling party is the subscriber to the service. If the calling party is the subscriber to the service, a query is sent to an IP address associated with the subscriber to retrieve information from an active application for completing a second leg of the call. The information may be a telephone number, or information which would permit the retrieval of a telephone number such as a name and address or an e-mail address. A directory service may be used to convert the information into a telephone number. Once a telephone number is obtained, the CTI hardware is used to complete the second leg of the call and the two calls are joined together. The advantage is a fast, convenient method of completing calls without dialling digits or manually converting one form of information into a diallable number.

Abstract: This invention provides a process for the denitration of combustion exhaust gas which is suitable for use as a countermeasure while the exhaust gas has a low temperature (e.g., during the starting of combustion equipment) or for the denitration of a low-temperature portion of the exhaust gas.        The aforesaid denitration process is a process for the denitration of combustion exhaust gas by passing the exhaust gas through an ammonia reduction denitrator, which comprises providing the exhaust gas flow path with a bypass having a low-temperature denitrator installed therein, on the downstream side of the ammonia reduction denitrator; while the exhaust gas has a low temperature, passing the exhaust gas through the bypass to perform the denitration thereof by means of the low-temperature denitrator; when the ammonia reduction denitrator has came to function properly, closing the bypass to perform the denitration of the exhaust gas by means of the ammonia reduction denitrator; and regenerating the catalyst within the low-temperature denitrator while the bypass is closed. In the aforesaid denitration process, a plurality of parallel-connected low-temperature denitrators may be installed in a section of the exhaust gas flow path where the exhaust gas temperature ranges from room temperature to 200°C, and successively changed over in such a way that denitration and catalyst regeneration are alternately performed.

Inventor: BOND GORDON S
IPC: C10G33/04
Filed: 1999-02-17
Abstract: Tar sand is upgraded to produce a hydrocarbon having a low concentration of water and solids by contacting a bitumen/diluent mix with an alkoxyalkylphenol alkoxylate surfactant prior to separation of a recoverable hydrocarbon phase. The separation of the bitumen/diluent mix into a recoverable hydrocarbon phase and a water/solid phase results in a recoverable hydrocarbon phase that meets the concentration of water and solids desired by tar sand processors. A further refinement of the method involves contacting the bitumen/diluent mix with an anionic and cationic flocculant following the surfactant for further improvement in separation.
