[Also in Group XXXIV] A screw-threaded iron core 1 has a coating of resilient thermoplastic material 2 applied to its surface under initial stress, so that smooth adjustment may be effected when the core is screwed into a supporting tube 5. The coating also takes up play between the threaded parts. The coating may comprise a tube or strip of film laid round the core or alternatively may consist of longitudinal strips of plastic material. The plastic material may be polyethylene or polyvinyl chloride.
