| X3573 RHO. c. Hs.{Lord Ernest Hives - Chair} -------- BY19/H.{Arthur M. Hanbury - Head Complaints} 28.8.24. -------- Mr.Brock has suggested trying our moulded synthetic material we produce in place of the Continental Bakelite we are using at the moment for our Slipper Drive Damper Plates. The reason he is putting it forward is that they can be obtained more accurately and with less variation in thickness per ring, that is, the faces of the rings are practically parallel to one another, whereas the Continental Bakelite in a number of cases shows as much as three to four thous. out of parallel per ring. In view of this, therefore, it would be advantageous to use Moulded Bakelite providing it has the necessary frictional characteristics and will withstand wear. We thought you might fit the four rings in question, with which we are supplying you, No.E.53172, to one of your 20 HP. experimental cars. BY.{R.W. Bailey - Chief Engineer} [STAMPED: BROCK] | ||
