| Ex. FROM DA. {Bernard Day - Chassis Design} Copy to HS. {Lord Ernest Hives - Chair} SHOCK DAMPERS. ORIGINAL DA {Bernard Day - Chassis Design} 1/M14.6.30. x7520 y5520. Some considerable time ago we sent through an idea for providing a slight amount of free movement in the middle of the shock damper stroke by introducing small air vessels into the body of the shock damper. We also sent a temporary method of applying the scheme to the existing dampers. We have not had any report as to results though we believe these air vessels have been tried. R. {Sir Henry Royce} has referred to the matter again just recently. We also asked that a patent should be taken out in the name of W. G. {Mr Griffiths - Chief Accountant / Mr Gnapp} Hardy. So far we have seen nothing of this, and should be glad if it could be pushed forward. DA. {Bernard Day - Chassis Design} | ||
