| Hs{Lord Ernest Hives - Chair}/Wst.4/AD20.4.32 contd. -2- AS regards the above performance figures, these are what we expect and if we materially improve the day output cutting in by reducing the field resistance we shall defeat the object of this resistance which, of course, is to prevent excessive over-charging the battery during the day. We are giving the matter our further consideration. Hs{Lord Ernest Hives - Chair}/Wst. | ||
