Title: Treating pulp with yield or strength-enhancing additive
Inventor: STROMBERG C BERTIL
IPC: D21C/
Filed: 2000-09-12
Granted: 2008-07-08
Abstract: Chemical pulp is produced from a slurry of comminuted cellulosic fibrous material using a beneficial additive such as AQ, or polysulfide. In the first treatment zone the effective alkali concentration and temperature conditions are such so that substantially no alkali degradation of the cellulose occurs, but so that the material is effectively impregnated with the additive. Then the material is treated with an alkaline cooking liquor, at cooking temperature, to produce a chemical cellulose pulp with higher yield or strength than if the low temperature, low alkali, additive pretreatment was not practiced. Typical alkali and temperature conditions in the first zone are less than 10 g/l expressed as NaOH; and between about 80-130°C, e.g. about 80-110°C. The first zone is preferably a feed system (which may include a separate impregnation vessel) for a continuous digester, while cooking is in a continuous digester.

Abstract: The invention concerns a separator for producing protective or delimiting road barriers, with an oblong horizontal section and comprising a cylindro-convex end (4) and a cylindro-concave end (5) for articulated interlocking or cylindrical articulation with the cylindro-concave end, respectively, of identical or similar neighbouring separators. Said separator comprises, at each of its ends (4, 5) at least a passage or orifice (6) allowing through at least a flexible link (7) for connecting it to a set of identical or similar separators for producing a barrier. The invention is characterised in that it consists of a hollow and empty body capable of containing a shock-absorbing air volume. The invention also concerns the protective or delimiting barriers constituted with such separators.

Title: Electronic lancing device
Inventor: RUGGIERO JOSEPH E
IPC: A61B5/15
Filed: 2000-11-01
Granted: 2006-09-19
Abstract: It has been discovered that the use of a substantially free-standing voice coil within a lancing device in coordination and combination with a stationary magnet and electronic circuit renders a much improved lancing device. The minimal weight of the free standing voice coil and the attractive forces of the magnet allow the battery-powered electronic circuit to maintain excellent control over the advancement and retraction of a lancet. When the electronic lancing device is initiated by a user, the voltage source within the electronic lancing device provides sufficient current through the voice coil such that the coil and lancet are repulsed from the magnet and propelled into the puncture site. The voltage source subsequently reverses the current through the voice coil to supply sufficient attractive current through the voice coil such that the dwell time of the lancet is minimized and the lancet is retracted from the puncture site and pulled toward the magnet within the housing of the electronic lancing device.

Patent CA-2328352-C (CA)
Inventor: KIM JAE-YOEL
IPC: H04W76/02
Filed: 2000-02-14
Granted: 2003-12-09
Abstract: Disclosed is a power control method for a mobile station which has at least one frame including a data transmission duration where data is transmitted at a first frequency, and a data transmission-off duration where a second frequency is searched to perform an inter-frequency handoff to the second frequency. The transmission power at the data transmission duration is increased to compensate for the loss of transmission power during the data transmission-off duration. In the method, a base station sets a power control threshold depending on the length of the data transmission-off duration. The base station receives power-increased data and compares the received power of the data signal with the power control threshold. The base station generates a power-up command when the power control threshold is higher than the receiving power, and generates a power-down command when the power control threshold is lower than the receiving power.

Patent CA-2331212-C (CA)
Inventor: SILVA MICHAEL
IPC: H04Q3/00
Filed: 1999-06-03
Granted: 2009-08-18
Abstract: The L4 application in the switch is expanded to permit functions previously performed exclu-sively in the L5 protocol application. Moreover, the L4 application is programmable by the system operator so that the system operator may expand the predefined set of L4 call management opera-tions to accommodate his call processing require-ments. Overall supervision of the call-management operations was previously limited to the L5 applications. However, the ability to program the L4 application enables the system operator to decide which call processing operations will be managed by the L5 applications and which operations will be managed by the L4 application. The system opera-tor may thus define, in the L4 application, a propri-etary call model that instructs the switching node to manage all incoming calls, or the system operator may specify the call model on a channel by channel basis. The latter arrangement programs the switch-ing node to use different call-processing protocols among the various channels. In addition, the user may either re-define or define entirely new appli-cation programming interface (API) calls for com-munications between the host and switching node and/or between the switching node and ports.

Abstract: A tool string, such as one used for performing fracturing operations or other types of operations, includes a valve, a valve operator, and a sealing assembly that in one arrangement includes packers to define a sealed zone. The tool string is carried on a tubing, through which fluid flow may be pumped to the sealed zone. The valve operator is actuated in response to fluid flow above a predetermined flow rate. When the flow rate at greater than the predetermined flow rate does not exist, the valve operator remains in a first position that corresponds to the valve being open. However, in response to a fluid flow rate at greater than the predetermined flow rate, the valve operator is actuated to a second position to close the valve.

Title: Directional resistivity measurements for azimuthal proximity detection of bed boundaries
Inventor: SONG HAOSHI
IPC: G01V3/30
Filed: 2000-02-10
Granted: 2004-09-28
Abstract: An azimuthally tunable resistivity measurement tool (202) comprises a set of three skewed receiver antennas (216, 218, 220) and a transmitter antenna (104, 108). The three skewed receiver antennas are oriented in equally spaced azimuthal directions. The transmitter antenna transmits a radio-frequency signal that propagates through the formation surrounding a borehole. Signals from the three receiver antennas can be measured and combined to synthesize the signal that would be received by a virtual antenna oriented in any desired direction. Virtual receivers oriented perpendicular to the tool axis and with variable azimuthal orientation can be synthesized. Orientation of such a virtual receiver that has a maximized receive signal amplitude can be used to identify the direction of a nearby bed boundary, and the maximized amplitude can be used to estimate the distance to the boundary.  In another embodiment, the tool comprises a set of three skewed transmitter antennas (208, 210, 212) and a receiver antenna (112). In yet anotherembodiment, the tool comprises a set of skewed transmitter antennas (208, 210, 212) and a set of skewed receiver antennas (216, 218, 220).

Granted: 2010-08-10
Abstract: A process for scheduling the travel of trains on a rail corridor. The rail corridor includes a plurality of siding tracks onto which trains can be sided when a meet or pass occurs with another train on the corridor. A gradient search process is used with a cost function to determine the optimum schedule by moving each meet and pass to a siding. The individual train schedules are varied by changing train speed and/or the train departure time (i.e., the time at which the train enters the corridor).
