| 1209 EJJ. from Rm.{William Robotham - Chief Engineer} c. to Hs.{Lord Ernest Hives - Chair} Rm{William Robotham - Chief Engineer}9/R.12.12.36. ELECTRIC DRIVE FOR ROAD WHEEL DYNAMOMETER DRUMS. Though provision was made for a variable speed motor to drive the road wheel dynamometer drums, its installation was deferred in order to expedite the completion of the rest of the equipment. We are now feeling the need for the variable speed motoring apparatus, and should, therefore, be glad if you could proceed with the installation of the motor. We are also ready for the second constant speed motor on the bump rig. Rm.{William Robotham - Chief Engineer} | ||
