Abstract: A method of selecting a washing cycle for an intelligent appliance uses several factors to make a cycle selection. The first factor is a combination of the water turbidity, conductivity and temperature as well as the wash arm speed. The other factors are the average of previously selected cycles, the number of times the appliance door has been opened, and the time between wash cycles. The appliance also allows the user to bump up the selected cycle to a higher cycle if the user is unsatisfied with the performance of the appliance. If a failure has occurred with any of the sensors or in the communications routine, the appliance selects the average of previously selected cycles as the wash cycle.

Abstract: A pump has a bearing stand (3) in which a pump shaft (1) is mounted to be driven by an electric motor. The shaft (1) mounts an impeller (9) having blades (10) which cause fluid entering through an axial inlet nozzle (11) to flow, by rotation of the impeller in one direction, through a centrifugal exit nozzle (12) formed by a suitably located quarter toroid (13a), and a half toroid (14), formed as sheet metal pressings. When the impeller (9) is rotated in the opposite direction, the centrifugal nozzle (12) acts as an entry nozzle and the axial nozzle (11) acts as a discharge nozzle. The pump is particularly suitable for treating textile yarns since said one direction of rotation can be used for out-to-in treatment dye liquor flow where relatively high resistance is encountered and said opposite direction of rotation can be used for in-to-out treatment dye liquor flow where resistance is relatively lower.
