| HS.{Lord Ernest Hives - Chair} FROM R.{Sir Henry Royce} C. to SG.{Arthur F. Sidgreaves - MD} WOR.{Arthur Wormald - General Works Manager} BY.{R.W. Bailey - Chief Engineer} E.{Mr Elliott - Chief Engineer} x 3456. R3/M6.12.32. Sent off 9.12.32. re. ANTI-SPILLING VALVE ON RADIATORS. I shall be very interested to know whether you are using on all our models the anti-spilling valve. This seems such a great improvement that it ought to be adopted in all sizes of radiators from P.2. to Peregrine, not only for its anti-spilling properties, but because it permits of a slight increase in temperature before boiling and loss of water occurs. It should be a good selling feature. Our experience with it in France was very good. R.{Sir Henry Royce} | ||
