Dear Sirs, - For the attention of Mr. Grylls - On Saturday we sent you eight servo motor moulded discs reference S.4419 for trial, and we shall be glad if you will try these out. They may be effective, although possibly too weak structurally, but this can be remedied. The main point we are interested in at the moment is the effect of temperature on the coefficient of friction. Yours faithfully, FERODO LIMITED. (Signature) Chief Engineer. | ||
