20150108937 | VALVE ACTUATORS - A valve actuator having a drive shaft, which, in use, is configured to adjust a valve between an open position and a closed position, an AC induction motor for driving the drive shaft a contactless position sensor configured to, in use, output a signal representing an angular position of the drive shaft or the valve, and a controller configured to control the AC motor in accordance with the signal output by position sensor. | 04-23-2015 |
20130341465 | ON BOARD INERT GAS GENERATION SYSTEM - An on board inert gas generation system for an aircraft receives air from a relatively low pressure source such as low pressure engine bleed air or ram air and passes it to a positive displacement compressor to increase the pressure thereof to be suitable for supply to an air separation module. All or a portion of the compressed air from the positive displacement compressor may be supplied by operation of a valve to one or more other aircraft components to provide at least one of power, heat or pressure thereto. | 12-26-2013 |
20130294950 | ON BOARD INERT GAS GENERATION SYSTEM - An on board inert gas generation system receives cabin air, or air from another relatively low pressure source, passing a portion thereof through an energy recovery turbine to ambient to extract power which is used to provide all, or part of the energy required to drive a positive displacement compressor to co press another portion of cabin air to increase the pressure thereof to be suitable for supply to an air separation module. | 11-07-2013 |
20130139521 | ON BOARD INERT GAS GENERATION SYSTEM - An on board inert gas generation system for an aircraft receives air from a relatively low pressure source such as low pressure engine bleed air or ram air and passes it to a positive displacement rotary compressor to increase the pressure thereof to be suitable for supply to an air separation module. The speed of the positive displacement compressor may be adjusted across a wide range in order to provide efficient operation in cruise and descent phases of aircraft flight. | 06-06-2013 |
