| EFC {E. Fowler Clarke - Electrical Engineer} 3/T20.3.25. -6- Contd. is suited to the present drive ratio of 1.2. We therefore suggest that our final form of fan might be considered as an experimental improvement upon the production form 15, and treated accordingly, and when the most satisfactory drive ratio has been decided upon, this might be standardised in the usual way.
