Abstract: A method of mounting a rotor assembly to a frame of an electric motor includes providing a rotor assembly having a bearing and a frame having a bearing seat. The method includes locating the bearing within the bearing seat, applying a first adhesive at a substantially hidden interface between the bearing and the bearing seat, applying a second adhesive at a substantially visible interface between the bearing and the bearing seat, and curing the first and second adhesives using different curing processes.

Abstract: A rotor that includes a rotor core assembly secured to a shaft. The rotor core assembly includes a magnet and an end cap secured to an end of the magnet. Each of the magnet and the end cap has a bore into which the shaft extends. The end cap forms an interference fit with the shaft. The magnet forms a clearance fit with the shaft and an adhesive is located in the clearance between the magnet and the shaft. Additionally, a method of manufacturing the rotor. The method includes inserting the shaft into the bore of the end cap. An adhesive is then introduced into the bore of the magnet and the shaft is inserted into the bore of the magnet so as to cause adhesive to be drawn into the clearance defined between the magnet and the shaft.

Abstract: A laundry appliance such as a washing machine includes an outer housing and a drum rotatably mounted therein. The drum has an inner wall and an outer wall separate from the inner wall, the inner and outer walls being perforated to allow washing liquid to flow into and out of the drum via the perforations. The area of the perforations per unit area of the outer wall is greater than the area of the perforations per unit area of the inner wall.

Abstract: The invention provides a method of operating a laundry appliance (10) comprising an outer casing (12) and a drum (50) rotatably mounted within the outer casing (12), the drum (50) having at least two rotatable portions (60, 70) which are capable of being rotated in either a synchronized mode or a non-synchronized mode, the method comprising the steps of: (a) introducing water to the interior of the drum (50); (b) heating the water to a desired temperature; (c) rotating the drum (50) to effect a washing action; and (d) spinning the drum (50) at a relatively high speed so as to remove water therefrom. In one aspect, the drum (50) is rotated in the non-synchronized mode either during or immediately after the step of introducing water to the interior of the drum (50). This helps to distribute the washing liquid throughout the wash load.

Abstract: A laundry appliance (100;200) comprises an outer housing (102;202) and a drum (122;222) rotatably mounted therein. The drum (122;222) comprises an inner wall (32;132;232,232a) and an outer wall (34;134;234,234a), the inner and outer walls (32,34;132,134;232,234;232a,234a) being perforated to allow washing liquid to flow into and out of the drum (122;222) via the perforations (42,44;42a,44a;42b,44b;42c,44c;42d,44d;42e,44e). According to the invention, the area of the perforations (44;44a;44b;44c;44d;44e) per unit area of the outer wall (34;134;234,234a) is greater than the area of the perforations (42;42a;42b;42c;42d;42e) per unit area of the inner wall (32;132;232,232a).

Abstract: Recoverable articles including an inner resilient tubular member that is held in a laterally expanded configuration by engagement with an outer holdout member are provided. The outer surface of the inner member is provided with a plurality of channels extending therealong. The holdout member occupies the channels so as to provide the holdout engagement. The holdout engagement is arranged to be weakened mechanically without any substantial change in the molecular structural properties of the holdout member, thereby to allow recovery of the inner tubular member towards its unexpanded configuration.

Abstract: A two part range-taking member for providing a seal around a substrate includes a mating pair of resilient components for enclosing the substrate and a co-operating pair of rigid components for urging the resilient components into conformity with the substrate. The member may provide an electrical stress cone for a power cable, for example with two such members being provided in a cable joint.

Abstract: A 15 kv cable joint is enclosed within two half shells filled with sealant material. Displacement or thermal expansion of the sealant is accommodated by various configurations of stress cones that have apertures or surfaces that are flexible and arranged to maintain pressure on the sealant for example during thermal cycling of the joint.
