Abstract: A method of manufacturing components, such as a steering wheel hubs, which are adapted to be mounted on a shaft comprises forcing a tubular insert (20) having a substantially uniform internal diameter into engagement with a mandrel having an external surface at least part of which (29) diverges to a diameter greater than the internal diameter of the insert, thereby deforming the insert so that its internal surface is cylindrical at one end and diverges outwardly towards the other end, moulding a body (30) around the insert whilst the insert is engaged with the mandrel, and disengaging the mandrel and the insert. Since the divergent part of the insert is not formed until immediately before the body of the component is moulded the number of faulty components having the insert located therein in an incorrect orientation is reduced.

Abstract: Improvements are made in the process wherein Li +  values are recovered from dilute aqueous solution by the use of an anion-exchange resin composite (C-1, C-2, C-3), containing crystalline LiX·2Al(OH) 3 , where X is halide. The improvements derive from enriching the Li +- containing solution with a non-competing metal salt (e.g., NaCl (S-1, S-2) prior to the Li +  removal, thereby achieving higher Li +  loading of the resin composite and obtaining more concentrated eluates. 
     The non-competing metal salts that can be used are the chlorides, bromides or iodides of the alkali and alkaline earth metals.
