| To PN.{Mr Northey} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} +8410 x1360 Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}1/LG24. 9.28. With reference to PN{Mr Northey}3/WT22. 9.28. We see nothing in our memo. which indicates that plated springs have been standardised. Cadmium plating has not been standardised. We believe the main trouble with our springs is due to digging in. Cadmium plating does not prevent this as the deposit is quite soft. We are therefore aiming at an improvement in spring design. Mr. Royce is not altogether in favour of cadmium plating as it is rather an expensive process. We are therefore making sure that we are getting some permanent benefit from it before we recommend its adoption. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
