| To R.{Sir Henry Royce} from Ck.{Mr Clark} c. to CJ. c. to E.{Mr Elliott - Chief Engineer} c. to Wor.{Arthur Wormald - General Works Manager} c. to Bn.{W.O. Bentley / Mr Barrington} c. to By.{R.W. Bailey - Chief Engineer} c. to Ds. c. to EP.{G. Eric Platford - Chief Quality Engineer} c. to PN.{Mr Northey} c. to Hs.{Lord Ernest Hives - Chair} X.3014 - LUCAS E.575 DYNAMO. X.295. - SMITH (T & M) TYPE A DYNAMO. Further to our Ck{Mr Clark}2/T4.3.20, we attach further comparative out-put speed curves of the Lucas and Smith dynamos. These were sent to you under cover of our EFC4/T12.5.19 and show, besides the comparative cutting in speed, the comparative rates of the rise of current both hot and cold. We attach copies of these curves also to Wor{Arthur Wormald - General Works Manager}'s and PN{Mr Northey}'s copies of this note as these were not sent to them at the time. Ck.{Mr Clark} | ||
