Abstract

A depth classification version of CC for compound Subjects going with the Host Subject Air Vehicle Wing Production is given. The methodology for the design of freely-faceted scheme for classification has been used. A large number of the isolates Constituting the different schedules for the classification of subjects going with each of the different Host Subjects for the production of the different parts and sub-assemblies of an aircraft such as Wing, Fuselage, Nose cone, Control system, and Landing system have common array divisions. Eight provisional schedules of such array divisions of isolates relevant to Subjects in the field of aircraft production are presented and their use in the formation of isolate numbers illustrated with examples. The schedules of common array divisions given are: Directional relation, Location, Shape of edge, Attributes of surface, Shape (General), Mach Number, Range of dimension, and Matetrial of construction. A provisional schedule of common organ isolates is also given. The Numerical Device is explained. The use of these devices help, in conforming to the; Canon of Helpful Sequence, the Canon of Consistent Sequence, the Canon of Scheduled Mnemonics, ,and the Law of Parsimony, in schedule building. In this way, the enumeration of isolates in the schedules has been reduced by about fifty percent. An Alphabetical Index to the schedules and a lift of twelve examples of subjects classified according to the scheme for classification are given.

Abstract

Explains the importance of bearings in modern industry. Defines bearing and shows that the (BC) 'D9k Bearing Production Engineering' has two (CC) 'D9kl Sliding bearing' and 'D9k2 Rolling bearing' which are themselves (BC) and gives a table of the first characteristics used as the basis for the classification of bearings. Shows the different parts of a bearing with the help of a diagram. Provides a tentative scheme for the classification of the subjects going with the (BC) 'D9k Bearing Production Engineering' for [1P]. Gives an alphabetical index to the schedule. Gives a classified list of twenty-seven examples classified according to the above scheme.

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.
