X6016. EP.{G. Eric Platford - Chief Quality Engineer} from Hs{Lord Ernest Hives - Chair}/Wst. C. Ck.{Mr Clark} H.{Arthur M. Hanbury - Head Complaints} Hs{Lord Ernest Hives - Chair}/Wst.3/KT.18.10.32. PROPOSED 20/25 THREE CHARGE SCHEME FOR DYNAMO. In accordance with your request, we attach herewith a few explanatory notes we have made regarding the operation of this scheme. Whilst we think this scheme is a big improvement over the existing two charge scheme, it still has certain disadvantages, the ideal scheme being a constant voltage controller dynamo.
