Introduction
September. Mr. Neale is well known for his distinctive contributions to tribology, his professional service to the community through his work on behalf of the Institution of Mechanical Engineers and his unrivalled knowledge of bearing design. His approach is based upon synthesis rather than analysis and his survey of the tribological features of reciprocating machinery provided the overall, unifying view which was so helpful to the presentations in subsequent sessions. The customary Tuesday night Symposium dinner was held in a nearby hostelry, The Lawnswood Arms, Adel, immediately after the Keynote Address. We were pleased to welcome not only the delegates but also a number of guests on this occasion. Our speaker was Dr. J.D. Summers-Smith, who was retiring from Imperial Chemical Industries after many years of service as lubrication adviser and resident tribologist. It was suggested that his speech might have wide appeal and we are therefore particularly grateful that he agreed to the publication of the edited version recorded in this volume. The programme was structured on thirty six papers, including selected reviews, presented in eleven sessions. Each presentation was supported by a substantial synopsis and the complete package of pre-Symposium literature was presented to delegates in neat wallets kindly supplied by the University Branch of the Midland Bank. Three sessions were devoted to bearings for reciprocating machinery, two to each of the subjects of lubricants, materials and components and one to piston rings and cylinder liners. This balance of subject weighting, which arose naturally from the 'call for papers', is an interesting reflection of the interests and efforts of research groups concerned with the tribological performance of reciprocating machinery. We were unfortunately unable to include all the papers offered, but hope that the manuscripts for a number of diappointed authors will be published elsewhere. The smooth running of the sessions was ensured by the skill of our chairmen and we are particularly grateful for their firm yet sensitive handling of the discussion periods. Authors and delegates readily joined in the now familiar procedure of filling-in discussion slips and our research students and fellows in the Institute applied the right amount of gentle pressure to ensure that the completed forms could be assembled by the editors. By capturing the immediate thoughts of all participants, the editors were able to construct the reports of the lively and extensive discussions for the benefit of readers of the proceedings. On the afternoon of Thursday 9th September 1982, delegates travelled to the river Humber east of Leeds to see the worlds largest single span suspension road bridge. The Humber Bridge was opened by Her Majesty the Queen on 17th July 1981 and it now presents a fine structure of stell and concrete linking Hessle to Barton on Humber. Most of the delegates took the opportunity to walk over the 1410m. long central span and s
