| R.R. 235A (100 T) (S.H. 169, 11-8-20) G.{Mr Griffiths - Chief Accountant / Mr Gnapp} 2800 ORIGINAL TO HS.{Lord Ernest Hives - Chair} FROM DA.{Bernard Day - Chassis Design} DA{Bernard Day - Chassis Design}/HDY{William Hardy}1/M10.7.25. DAMPED SPRING DRIVE FOR PENDULUM LEVER. X8020 We understand that you would like more friction in the damped spring drive, and weaker torsion springs. Will you kindly let us know the strengths of the springs you are actually using, both for torsion and for friction, so that we may have some basis for our calculations.
