Title: Method for converting the energy of compressed gas into useful work and gas turbine (combined cycle) power plant for implementing the method
Inventor: AKHMEDOV RUSTAM BEROVICH
IPC: F02C3/22
Filed: 1999-03-12
Abstract: The inventions related to power generation.      A method includes feeding a fuel and a compressed gaseous oxidant which is a mixture of oxygen with carbon dioxide at the oxygen concentration of essentially 21 percent, into a combustion chamber of a gas turbine (combined cycle) power plant, burning the fuel at the oxidant excess factor maintained in the burning zone within the range from 1.05 to 1.15 percent, the oxygen being obtained by separating air into oxygen and nitrogen, and the carbon dioxide being extracted from turbine exhaust gases.      A gas turbine (combined cycle) power plant comprises a combustion chamber (9), a compressor (6), a gas turbine (11) and a steam generator (14) or a waste heat boiler and a contact economizer (15) for cooling below the condensation point. The power plant further comprises an air separation unit (1) and a blending chamber (5). The invention ensures the substantially reduced detrimental emissions of nitrogen oxides, and the increased carbon dioxide concentration in the combustion products which makes the recovery of carbon dioxide economically profitable.

Title: Power steering apparatus
Inventor: KAJI HIROAKI
IPC: B62D5/065
Filed: 1997-08-13
Abstract: A motor is stopped when a steering angular speed is not greater than a stop threshold VS and a motor electric current value Im is kept within a motor stop range .DELTA.I for a predetermined time period. The value of a steering torque increases as the motor electric current value Im increases.      Therefore, the motor can assuredly be stopped when the steering torque is small. Further, when the motor is off, the sensitivity for motor actuation with respect to a change in the steering angle is set higher as the value of the steering angle increases.

Title: Partial splitter vane for reaction hydraulic turbine
Inventor: COULSON STUART THOMAS
IPC: F03B13/08
Filed: 1999-08-06
Abstract: An elbow shaped draft tube for a reaction hydraulic turbine has a splitter vane mounted within the draft tube that partially extends between 50% and 80% across the width of the draft tube to redirect flow about said elbow in the draft tube. The partial splitter vane has opposing side edge surfaces spaced from the side walls of the draft tube to allow the peripheral flow to swirl around the splitter as it moves through the draft tube. The splitter vane does not result in any efficiency decrease for operating conditions below peak efficiency flow rates and still provides the full benefits at flow rates above the peak efficiency flow rate for a given head. The splitter vane results in much lower static and dynamic loads due to its smaller surface area and minimal blockage of the swirl component of the flow. A plurality of support posts are embedded at one end in the draft tube and connected at the other end to position the splitter vane in non-contacting relation with the side walls of the draft tube.

Title: Magnetometer detection of fatigue damage in aircraft
Inventor: CLARK DAVID C
IPC: G01N27/90
Filed: 1998-03-13
Abstract: An apparatus and a method of detecting wide spread fatigue damage (WFD) on aircraft using the absolute conductivity of the metal. A meandering winding magnetometer (MWM) having a plurality of parallel spaced linear conductor elements are placed in proximity to the aircraft. An electromagnetic field is imposed on the aircraft and the resulting response is sensed. The response is transformed to determine the conductivity of the aircraft structure. The mapping of the conductivity of the aircraft structure produces an indication where microcracks are located in the structure. These early indications of the density, spatial distribution and spatial orientation, as well as the size, of the microcracks give the user an indication of WFD.

Abstract: An electronic door lock is programmable to accept new valid data key devices using a special data key device from with a set of special data key devices used for programming and control purposes. The lock has a learn mode controller responsive to a learn data key device to enter into a new valid access data key learn mode. A valid access code recorder is responsive to a first previously unknown code contained in a first new data key device while in the learn mode to record the first unknown code as a valid access code for operating said lock. A cancel code recorder is responsive to a second previously unknown code contained in a second new data key device while in the learn mode to record the second unknown code as a cancel code paired with the valid access code of the first new data key device. In use, the lock is activated to open in response to the valid access code of the first new data key device, and is activated to cancel the recorded valid access code in response to the cancel code of said second data key device. The lock is able to operate with any data key device without requiring preprogramming specific to the lock. Programming and control is made easier by hierarchical distinctly labeled special data key devices used for specific corresponding programming and control purposes.
Patent CA-2292173-A1 (CA)
Inventor: GERHARDT KLAUS
IPC: B27N3/14
Filed: 1999-12-14
Abstract: The invention concerns a roller sifting or dispersing machine for the classification or dispersing of wood chips, fibers, or similar materials, having at least one roller set composed of several rollers axially aligned in parallel and having the same rotation direction; together, these rollers form a roller bed that extends longitudinally at right angles to the rollers and is equipped with an input end for the material to be sieved and an output end for the course material, whereby each roller's upper side turns toward the output end; the rollers are equipped with numerous annular grooves axially equi-spaced and separated by annular crosspieces that form the outer sheathing surface of the roller. Adjacent rollers are arranged so that the annular cross members of one roller are opposite the annular grooves of the other roller, thus being largely closed along their circumference when viewed along the roller bed surface, but having openings for the passage of chips in the direction perpendicular to the roller bed surface. For improved sifting or classification the invention proposes that the annular grooves as well as the annular crosspieces be located perpendicular to the roller surface and that the outer sheathing surface of each annular crosspiece be equipped with circumferentially aligned teeth whose leading sides are shaped more steeply than their back edges leading to the base of the following tooth side, whereby an axial view of the annular crosspiece teeth is seen as a gradient that is in the opposite direction to that of the adjacent roller but is of the same height.

Title: Accommodation of data definition statements in the sharing of dynamic sql statements
Inventor: CHAN YUK-KUEN
IPC: G06F16/2455
Filed: 1999-12-22
Abstract: An SQL relational database management system which determines the shareable status of an executable object (section) in an SQL cache. The shareable status is defined for a section in an SQL cache by the system maintaining an identification list which has reference to database entities which are affected by a DDL statement in the current unit of work. When an SQL  statement is compiled, the compiler generates a list of dependencies, which list is compared with the identification list. If the SQL statement data dependencies are on the identification list, the SQL  statement will be treated as non-shareable until the completion of the current unit of work.
