Abstract

Works out a scheme for the classification of the subjects going with the (BC) "D9c3 Screw Production Engineering", to demonstrate the methodology for the design of classification described in Paper A in this issue. The schedules given are confined to the first characteristics for (IP) only. Gives an  alphabetical index to the schedule. Gives a classified list of twenty examples classified according to the above scheme.
