Patent CA-2299575-A1 (CA)
Title: Power control device and method for reverse link common channel in mobile communication system
Inventor: KIM YOUNG-KY
IPC: H04B7/005
Filed: 1999-07-13
Abstract: A method for controlling the transmission power of the reverse common channel for a mobile station in a CDMA communication system. In the method, the mobile station transmits a preamble signal at predetermined periods with increasing transmission power. Upon receipt of an acknowledge signal from a base station, the mobile station accesses the reverse common channel. In order to avoid multiple mobile stations from simultaneously generating increasingly powerful and interfering transmissions, the method generates two transmission power control signals: one based on the measured strength of a signal received from the base station and the other based on an accumulated value of power control commands transmitted by the base station. These two signals are accumulated and used to control the preamble signal.
Patent CA-2299803-A1 (CA)
Inventor: GRAVEL MARC ANDRE
IPC: F16L1/036
Filed: 2000-03-01
Abstract: A method and apparatus for laying pipe with bell and spigot connections in a vertical wall trench. A first step involves providing a rigid guide chute having a feed end and a discharge end. The guide chute is radiused within deflection limits for pipe to be used. A second step involves mounting the guide chute to a mobile support. This enables the guide chute to be moved along a pipeline right of way. A third step involves inserting the discharge end of the guide chute into a vertical wall trench. A fourth step involves using a pipe feeder at the feed end of the guide chute to exert and maintain a force upon a pipe string sufficient to maintain all bell and spigot connections of the pipe string engaged during insertion.      The guide chute prevents the force exerted by the pipe feeder from excessively deflecting the pipe string during insertion.
Patent CA-2302231-A1 (CA)
Inventor: HOLLINGSWORTH JIMMY LAWRENCE
IPC: E21B19/20
Filed: 1998-09-02
Abstract: An apparatus is provided with position sensors. When the apparatus has moved one tubular into alignment with another tubular a button on a remote control console is pressed to memorise the position. After the next tubular has been gripped by the apparatus a "recall" button is pressed and the apparatus automatically moves the next tubular to the memorised position. This saves vital seconds in joining tubulars and also reduces the likelihood of threads being damaged due to misalignment of the tubulars.

IPC: H05H1/36
Filed: 2001-01-02
Abstract: A process and apparatus for stopping a cutting operation of a plasma arc torch is disclosed which minimizes the oxidation of the electrode to thereby extend life of the electrode. A flow of oxidizing gas is directed through a plasma chamber and nozzle. An electrical current is then conducted through the electrode to form a plasma arc. The electrical current is cut no later than a time F for extinguishing the plasma arc. The flow of oxidizing gas is switched off a determinable time interval before time F, and a flow of non-oxidizing gas is switched on no later than time F, whereby the non-oxidizing gas substantially completely purges the oxidizing gas from the torch creating an inert environment, whereby the plasma arc extinguishes in the inert environment.

Patent CA-2330778-A1 (CA)
Inventor: VANDERVEEN MICHAELA C
IPC: H04L12/28
Filed: 2001-01-12
Abstract: The defined boundaries in a network are pushed down to the base station level. Doing so necessitates authentication each time a wireless terminal switches communication, or "handoffs" from one base station to another. To achieve such authentication in an efficient manner, security information, i.e., the derived information, is transferred from one base station directly to another. By directly it is meant without accessing any other source of the derived information, although the information may be transferred via other intervening nodes of the network that form an interconnection path for the base stations. A simplified network, i.e., a network with reduced hierarchy from a control point of view, e.g., one that only requires home location register and base station network entities along with interconnection therefore, may be employed with a minimal decrease in performance, e.g., a minimal increase in delay, during the handoff process. In one embodiment of the invention, a first base station which initially receives a service request from a wireless terminal requests authentication information from a central security node and receives in response at least, one, but typically two or more, sets of security information. When it is time for a handoff from the first base station to a second base station, the first base station transmits to the second base station at least one of the sets of security information it received from the central security node. The second base station then uses the information it received from the first base station to authenticate the wireless terminal.
