Abstract: A rotary positive-displacement fluid machine comprising a rotor eccentrically mounted in a casing for rotation about an axis, the rotor having recesses respectively receiving vanes which oscillate in the recesses as the rotor rotates. Each vane is connected by a crank to an arm for oscillation about a vane axis which is located inwards of the outer extremity of the tip which itself has a clearance fit within the casing. The tip of each vane is preferably curved about an axis parallel to the respective vane axis. The machine may be connected to the crankshaft of an internal combustion engine and driven by the pressure difference between the ambient air and that at the engine inlet manifold. Alternatively, the device may be operated as a heat pump.

Abstract: A method is provided that can include providing a computer, storing data records in the data store, processing the data records to form a hierarchical chart that reflects a relationship field and displaying the hierarchical chart on the display device. Each data record can include an identifier field, a relationship field, and a quality assurance field, where the relationship field for at least one of the data records defines a hierarchical relationship with at least one of the other of the data records. The computer can include a processing device, a display device, a storage device, and a data store. A computer program and system are also provided.
