Title: Refiner control method and system
Inventor: JOHANSSON OLA M
IPC: D21D1/30
Filed: 2001-03-08
Granted: 2006-08-29
Abstract: A system and method for monitoring and controlling operation of a disk refiner (32). The method regulates operation in response to a process variable (242) preferably in relation to a setpoint (256). The variable can be temperature, pressure, and/or stock consistency, refiner energy, or a variable based thereon. Volumetric flow rate of stock and/or the flow rate of dilution water can be regulated. Where temperature is used, it preferably is a temperature inside the refiner or adjacent the inlet or outlet. Where pressure is used, it preferably is a pressure inside the refiner or adjacent the refiner inlet (114a, 114b) or outlet. Stock consistency can be determined using a sensor (70) upstream or downstream of the refiner or using a sensed parameter in the refiner.

Title: Call management method responsive to network presence
Inventor: GARG AMIT
IPC: H04W4/20
Filed: 2002-12-13
Granted: 2007-07-17
Abstract: A call management method that provides for handling, according to subscriber- designated preferences, an incoming voice call to the subscriber while logged on a network. When the subscriber occupies a line, the method includes activating an Internet presence server that determines online status by checking IP activity at the subscriber's IP address. If the subscriber is online and has indicated a preference to accept calls, a pop- up screen is activated at the subscriber's terminal to display menu options to handle the call, such as answering via VoIP, text-to-speech synthesis, forwarding the call to a specific number, or sending the call to voicemail. A voicemail message may also be sent to an e- mail account as an audio file or as a pager alert with short message text. Certain management features may be disabled dynamically in response to the on-line status of the subscriber.

Patent CA-2431604-C (CA)
Inventor: WALKER STACY JAMES
IPC: F04B47/00
Filed: 2003-06-10
Granted: 2006-06-06
Abstract: A method of circulating through a reciprocating downhole tubing pump and a reciprocating downhole tubing pump. The reciprocating downhole tubing pump has a standing valve assembly and a travelling valve. The method involves displacing and disabling, without removing, the standing ball valve assembly and the travelling valve. This can be done with pins which knock the balls out of position or by enclosing the balls in cages which can be mechanically moved out of position with linkages. With the standing ball valve assembly and the travelling valve disabled, circulation can occur through the reciprocating downhole tubing pump. This has a number of advantages, such as removal of blockages due to sand accumulation.
Patent CA-2436431-C (CA)
Inventor: HOEPFL THOMAS
IPC: C01B31/00
Filed: 2002-01-30
Granted: 2007-06-26
Abstract: The invention relates to a device and a method for producing samples from predominantly dust-like and dry material, especially dust-like residues of combustion such as filter ash or flue ash, for determining the residual carbon content by determining the change in electrical parameters of a complex electrical component containing the produced samples to be examined.  The aim of the invention is to solve the technical problem of easily obtaining suitable samples from dust-like and dry material such as filter ash or flue ash having extremely bad flow behaviour, enabling the residual carbon content to be determined with a high level of precision according to the described method. To this end, the flue ash is transported into the complex electrical component (3) by means of a screw conveyor (2) and is compressed until a rapid, significant increase of the compression force is indicated. It was observed that during the compression of flue ash, a rapid increase in compression force of over 200 % is produced when a defined reproducible degree of compression is obtained, without any further increase occurring in the degree of compression.  Possible samples having defined compression ratios can thus be produced, said samples enabling a sufficiently precise determination of the residual carbon content.

Title: Method of logging a borehole
Inventor: SAMWORTH JAMES ROGER
IPC: G01V/
Filed: 2003-09-10
Granted: 2010-11-23
Abstract: In the field of wellbore data logging it is known to use isotopic neutron sources in a neutron capture logging technique. However, continuous isotopic sources are unpopular for regulatory and safety reasons. Attempts to employ neutron generator tubes to generate neutron bursts for use in the neutron capture technique have encountered various difficulties in areas connected with signal identification and processing. The disclosure relates to a method of data logging in which a low burst rate neutron generator tube is pulsed at comparatively low rates to generate neutron bursts that are captured in atomic nuclei in a proximal formation. The gamma radiation arising from the neutron capture is detected over a gating intervals defined by temporally distinct points. The gamma detector output is integrated over the gating interval to provide a measure of the decay rate that is independent of the pulse rate. Consequently the signal processing problems do not arise.

Title: Delayed egress exit device
Inventor: WHITAKER ANDREW
IPC: E05B47/06
Filed: 2002-09-30
Granted: 2011-04-12
Abstract: A touch bar (24) exit device (20) comprises a retractor element (50) disposed in the housing (22) for substantially rectilinear movement. The retractor element (50) connects the touch bar (24) and the latch bolt (82) such that the retractor element (50) and the latch bolt (82) are moved toward the retracted position in response to movement of the touch bar (24). An electrically energizable locking mechanism (104) in the exit device (20) includes a reciprocating plunger (106) moving transverse to the retractor element (50). When energized, the locking mechanism (104) is operative to move the plunger (106) to the projected locking position to prevent retraction of the latch bolt. A time delay circuit is connected to the locking mechanism (104). A switch (120) actuated in response to movement of the touch bar (24) is connected to the time delay circuit for starting a predetermined time interval for temporarily delaying deenergization of the locking mechanism (104). When the time delay circuit interrupts power to the locking mechanism (104), the plunger (106) moves allowing the latch bolt (82) to move to the retracted position.

Abstract: A movable barrier operator (11) transmits status signals from time to time to reflect its own operational states. A corresponding wireless remote control apparatus (14) receives such status signals and used the informational content of such status signals to effect a variety of automatic and/or user-facilitated control strategies. In one embodiment, the wireless remote control apparatus can use the status signal to determine a distance (or at least an approximate distance) between the movable barrier operator and the wireless remote control apparatus. This distance information, in turn, can also be used to inform and enrich the control strategies and possibilities of the wireless remote control apparatus.
