Tribology and reliability Indian Society for Industrial Tribology and National Productivity Council
An advanced training programme on 'Tribology and reliability' was jointly organized by the Indian Society for Industrial Tribology and the National Productivity Council, New Delhi. A b o u t 35 senior managers, engineers and scientists were selected for this programme o f lectures and discussions relating to industrial problems. The lectures were arranged to deal with tribological topics which have immediate application in industry and four sessions were entirely devoted to case studies. A b o u t 80 problems were set and these are available in booklet form.
The training programme was inaugurated by Dr M.S. Pathak, a member of the Government Planning Commission, who emphasized the need for such applied work in the country and asked the organizers to submit a blueprint on D2 Blondeel, E. and Snoeys, R.

Gulhati gave a very interesting lecture on petroleum products and base stocks, which encouraged the participants to consider lubricant savings assuming the economical recovery of the used oil to be possible. This led to a discussion of the means and methods for economical use of lubricants and the trend for the future developments and recovery methods and maintenance of machines. Control fluids and their importance in modern industries were discussed by Kumar and the need for high speed fluids for control was discussed by the participants. A talk on the design aspect of the boundar3; lubricants and their additives and its importance in the economical use of lubricants and the increased wear life of machine parts was given by Sharma. Subsequently, many design problems relating to the choice o f lubricants and compatible materials were discussed in the light of the present heavy breakdown in industry due to increased wear and consumption of spares. A lecture on the hydrodynamic theory o f lubrication of bearings and gears was delivered by Rao, and the design and selection criteria for slideways discussed by Nakra, who gave interesting clues to the solution of tribological problems faced at the design stage. Planned lubrication was discussed by Srinivasan, who emphasized its importance in the Indian economy in order to maximise the mechanic al efficiency of production and process equipment. The participants emphasized that they felt a need for a National Tribology Centre, and a resolution to this effect was unanimously passed for the consideration o f the Indian Government. J. P. SHA RMA
The series of lectures started with an introduction to tribology by Sharma and this was followed by lectures and discussions on lubricants and additives by Rao and Tripathi. These lectures were practically oriented to the choice of the right type of commercial lubricants and additives for machine parts to ensure increased wear life. Synthet-
