| EFC2/AM14.12.29 contd. -9- The question of modification of existing arrangements of machines to keep up the curve at high speeds rather higher than it is in some cases at present, is having consideration, it is almost certainly impossible however, to do this without interfering with the early stages of a curve. In particular one degree finer gauge field windings are being instructed for trial in each case 20 HP. and Phantom II dynamos of Intermediate type. EFC. | ||
