| 3035 To Roy.{Sir Henry Royce} From Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} c. to Wor.{Arthur Wormald - General Works Manager} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}5/MJ.18.3.33. We require two rev. counters for our Hotwell pump and shock absorber test rig. The most suitable type of counter is the one making two complete revolutions of the counter face which you have previously obtained for us. These counteres are graduated to give readings over 10 revs/min. We should like two instruments reading from 0 - 4000 R.P.M. i.e., one complete revolution of the hand to be 2000 R.P.M. The instruments which we are at present running on test has no type or designation, but the number on it is 32177. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
