| x.719 To ROY.{Sir Henry Royce} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Rn{Mr Robinson}7/LG31.1.29. x4466 Will you please ask the makers of Raybestos, Tenoid, and Ferodo to supply us with sample friction discs to G.76792. Our requirement for this disc is the maximum coefficient of friction that can be obtained with consistency. The discs will be subjected to no appreciable temperature rise and the rubbing velocity is exceedingly low. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
