Abstract: A screw has a screw tip defined at a forward end of the screw. A screw head is formed at a rear end of the screw. A screw thread helically extends from adjacent the screw tip towards the screw head. The screw thread has a series of successive screw thread portions each helically extending through 360 degrees. At least one flute extends from adjacent the screw tip towards the screw head through at least one of the screw thread portions. For each flute, a leading edge region of each of at least one screw thread portion through which the flute extends is convexly curved. Each leading edge region is defined by a trailing wall of the flute adjacent a crest of the respective screw thread portion.

Abstract: Methods and apparatuses are disclosed for providing integrated management of a workflow for moving industry quotes. A processor can be configured to execute workflow management software to manage a plurality of moving industry quote workflows. Each moving industry quote workflow may correspond to a move transaction. The moving industry quote workflows may correspond to a plurality of workflow types, and each workflow type may comprise an associated plurality of interrelated tasks for different aspects of managing a moving industry quote workflow. Users can interact with a plurality of graphical user interfaces (GUIs) to perform the interrelated tasks.

Abstract: A thrust demand signal is provided to a processor of a gas turbine engine and is modified, according to growth time constants of a rotor and/or a casing of the engine, in order to control the rotational speed or the rate of change of rotational speed of the engine so as to prevent contact between the rotor and the casing.

Abstract: A method of controlling an aircraft gas turbine engine cooling system. The cooling system includes a heat exchanger having a first fluid path through which fan air flows, and a second fluid path through which relatively hot compressor air flows. The cooling system includes a valve configurable between an open position corresponding to a first operating mode, where fan air flows through the first path cooling the compressor air in the second path to a lower temperature, and a closed position corresponding to a second operating mode, where fan air may flow through the first path at a reduced rate, thus the compressor air in the second path could be cooled to a lesser extent. The valve is operated in first mode when the aircraft is in a descent mode, or when turbine entry temperature is above a predetermined amount. Otherwise, the valve is operated in second mode.
