Kindly note that Mr Royce wishes us to leave these alone until the Exide show signs of a failure. He also wishes you to find out how the accumulator people avoid sulphating. Will you please let us have this information. With reference to the accumulators, Mr Royce says that to put the active material in the large block is not considered by accumulator people to be a success. The expansion and contraction between the peroxide state and the spongy lead state being rather an excessive amount. p. Wor.{Arthur Wormald - General Works Manager} | ||
