X.6028 X.6076 With reference to Ry/RD4/W13.4.31, this is to confirm the verbal agreement that should be 48 coil armature with the 20 conductors per slot, in conjunction with tapered poles, prove to be sufficiently good, then in view of the urgency of the matter and the desire to use existing material, this combination of armature and carcase shall go forward for standardisation. This implies that the work on armature D.73259 and the increased concentric air gap will be put in abeyance pending a more convenient time for threshing it out. HS{Lord Ernest Hives - Chair}/CAP. | ||
