| EFC {E. Fowler Clarke - Electrical Engineer} 1/AD30.1.30 contd. -3- convention of indicating inductive windings by spirals, and purely resistive windings or resistances by straight zigzags. You will see by my note EFC {E. Fowler Clarke - Electrical Engineer} 7/AD28.1.30 addressed to PN. {Mr Northey} that we regard the provision of reduced charge switching as an essential feature of the scheme of utilising generators of "higher output".
