Abstract: A lined and flanged bush and method of manufacturing the same comprising: providing a liner having an aperture; locating the aperture in the liner around the spigot such that the liner lies on the surface; and stamping out the blank around the spigot to provide a lined and flanged bush.

Abstract: A spherical bearing arrangement comprising: a bearing housing; a plurality of split-ball portions which are together arranged in the housing to produce a composite ball having a spherical bearing surface, the composite ball having a bore passing therethrough, the bore having a central axis; and a bushing secured in the bore of the composite ball. A method of assembling a spherical bearing arrangement is also disclosed.

Abstract: A cutting head for an electric razor is described. The cutting head includes a blade support member and a plurality of blades. The blade support member can attach to an electric razor and reciprocate back and forth. The plurality of blades are located on the blade support member, and move in a cutting direction towards a hair to be cut. The plurality of blades meet the hair to be cut at a contact angle that is acute with respect to the cutting direction.

Abstract: A generator includes a shaft and rotor body defining poles and a winding positioned around the shaft on the rotor body. A rotor pole crossover is aligned to the shaft and connects ends of the winding between adjacent poles. The rotor pole crossover includes a body member having a curved medial section and opposing legs extending outwardly from the curved medial section that connect to the ends of the winding. The curved medial section has at least one slot formed therein to add flexibility to the rotor pole crossover.

Abstract: A split ball portion for a spherical bearing arrangement, which split ball portion is to form one of a plurality of split ball portions to be arranged together in a bearing housing of the spherical bearing arrangement to form a composite ball, the split ball portion comprising: an outer bearing surface; at least one separation face, which lies adjacent a separation face of a neighbouring split ball portion when forming the composite ball; and at least one axial end face, the split ball portion comprising at least one chamfer surface at the junction of at least the outer bearing surface, a separation face and an axial end face.

Abstract: A waste gas recovery system employs a compressor which takes in waste gas from an inlet knock-out drum and passes compressed gas to a heat exchanger which cools the gas prior to passage through a further outlet knockout drum. The compressor is driven at a speed which is selected in accordance with the sensed pressure of the incoming waste gas and a valve progressively controls the supply of gas to the compressor inlet in accordance with the sensed pressure. Liquid condensate from the knock-out drums collects in a header tank. A temperature sensing and control arrangement injects liquid from this tank at the inlet to the compressor in the event of an excessive temperature rise at the outlet of the compressor. Gas is also re-circulated from the output of the system to the compressor inlet should the injection of liquid be insufficient to reduce the temperature rise.
