| 20090320777 | Control System - A control system is described that comprises a manifold, at least one valve device operable to control the delivery of fluid from the manifold, and a drive member located within the manifold and rotatable to control the operation of the at least one valve device. | 12-31-2009 |
| 20090236947 | Piezoelectric materials - A piezoelectric perovskite mixed oxide compound has the general formula (BiFeO | 09-24-2009 |
| 20090126802 | Fuel Staging System - A fuel staging system comprises a splitter valve arranged to split an input fuel stream into a pilot fuel stream and a main fuel stream, the splitter valve comprising a spool slidable within a bore, the spool and bore together defining first and second control chambers, the fluid pressures in which determine the position occupied by the spool, the system further comprising a control line which, in use, controls fuel delivery through a plurality of main burners, the fluid pressure in the control line being a combination of the fluid pressures in the first and second control chambers. | 05-21-2009 |
| 20090093918 | Control Arrangement - An aerospace control arrangement comprising a control unit connected to a plurality of connecting node sets, each connecting node set having associated therewith a plurality of connecting nodes, and each node having associated therewith at least one effecter and/or sensor, resulting in at least some of the nodes being connected to the control unit in a fault isolated star, point to point, arrangement. | 04-09-2009 |
| 20080294311 | Fault Diagnostics - A fault diagnostics technique for use with an engine controller and a hydromechanical device including a memory device comprises the steps of using diagnostics characteristics data stored in the memory device to modify a fault diagnostics algorithm of the engine controller, and using the modified fault diagnostics algorithm in conjunction with real time operating data from the hydromechanical device to determine whether the hydromechanical device is operating correctly. | 11-27-2008 |
| 20080291964 | Temperature Sensing - A TGT measurement system comprises a plurality of thermocouples connected in parallel to a distributor, and a data storage device carrying calibration data relating to at least one of the thermocouples. | 11-27-2008 |
| 20080236549 | Fuel System - A fuel system comprises a first, variable displacement fuel pump operable to supply fuel through a metering valve to an engine, a control servo operable to control the operation of the first pump, a pressure drop control valve (PDCV) responsive to a pressure drop across the metering valve, a second fuel pump, and a spill valve movable between an open position in which substantially all of the fuel supplied by the second fuel pump is returned to an inlet side thereof, and a closed position, or partially closed position, wherein a proportion of the fuel supplied by the second pump is delivered to the engine. | 10-02-2008 |
| 20080218036 | Rotating Rectifier - A rotatable rectifier arrangement comprises a rectifier component | 09-11-2008 |
