Dear Sirs, We thank you for your letter FW/JS.{Mr Johnson's Secretary} of the 10th inst. We had not realised that your rotational accelerometer was belt driven. We know that a belt does not transmit the torsional vibrations we are investigating, and regret therefore that your instrument would be of no use to us. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
