Patent CA-2310307-A1 (CA)
Title: Voice-over-ip enabled chat
Inventor: BURG FREDERICK MURRAY
IPC: H04M3/42
Filed: 2000-05-30
Abstract: A network-based system and method for providing anonymous voice communications using the telephone network and data communications links under the direction of a Call Broker and associated network elements. A user (the call initiator) present in a text chat room session establishes a data connection to Call Broker and, after qualifying for access (e.g., using credit card information) and providing a callback number, receives voice session information and participant access codes for each desired participant in a voice call. The initiator causes session information and participant codes to be passed to one or more selected chat participants in the current text chat room. When a selected participant uses the received session information, and enters the received participant code and a callback number, the Call Broker in cooperation with a Network Adjunct Processor (NAP) completes voice links to the initiator and the selected participant(s). The need for each party to have a second subscriber line is advantageously avoided by having the Call Broker arrange to have one or more voice links completed through a VoIP link, and further reduces the need for second lines for participants by forwarding a Call Broker - placed call to a busy participant line to the participant's Internet Service Provider (ISP), which then sends a message to the participant announcing one or more options for receiving the incoming call, including receiving the incoming call through a VoIP link.
Patent CA-2310893-A1 (CA)
Inventor: DESROSIERS GEORGES J
IPC: E21B7/02
Filed: 2000-06-05
Abstract: Apparatus for blast hole drilling includes a hammer and drill bit driven by a hydraulic drive motor outside the hole through a drill string extending along the drilled hole to the drill bit. The drive motor is carried on a mast with a telescopic hydraulic cylinder driving the motor along the mast in a forward direction for forwarding the drill bit along the hole to the rock face and for applying a feed force on the drill bit at the rock face and in a rearward direction for reducing the feed force and for withdrawing the drill bit from the hole. The cylinder assembly has a pulldown pressure side fed at a constant supply rate and a holdback pressure side controlled to discharge the fluid when moving downwards and to supply the fluid at a constant rate when pulling up. The control system includes a first valve for controlling a rate of supply of fluid to the motor for controlling the rate of rotation of the drill bit, a drilling valve operable to supply fluid to the pulldown side or to the holdback side, a second valve for controlling the rate of supply of fluid to the pulldown side, a third valve for controlling the rate of discharge of fluid from the holdback side, a hydraulic feedback line for communicating an increase in pressure of the fluid at the motor, caused by an increase in resistance to the rotation of the drill bit, to the holdback side of the so that the rate of forward movement of the drill bit is varied in proportion to changes in the pressure at the motor and a pressure switch responsive to pressure of the fluid at the hydraulic drive assembly exceeding a predetermined pressure limit to repeatedly cycle an upward and downward movement of the drill bit until the overpressure condition clears or until a number of cycles is completed.

Patent CA-2361242-A1 (CA)
Inventor: SINCLAIR JAMES WALLACE
IPC: G06Q10/04
Filed: 2001-11-02
Abstract: This invention addresses the need for dealing with complex planning calculations based on data warehouse or Planning Data Repository (PDR) data where some aggregat ed data or forecast data might be changed without directly manipulating the underlyi ng data, and where there may be several relationships linking the data. The system is abl e to deal with complex relationships along more than one axis or dimension. A number of iterations are typically used involving both back-solving and 'forward-solving'. The subset  of cells that needs to be recalculated is identified before steps of back-solving and/or forward-solving using parent/child tables. The scanning of these tables looking for potentia l dependencies is much simpler and faster than to looking at the actual formulae or functio ns relating the cells. The step of creating the parent/child tables is carried out in advanc e of the actual calculation by parsing all the relationships (formulae and functions) and summarising the dependencies between cells in the parent/child tables.
