| - 2 - E. {Mr Elliott - Chief Engineer} Fowler Clark Esq. 17th February, 1926. a lower charging P.D. and a greatly improved performance at high rates of discharge - an increase in volume of electrolyte amounting to 20% more than obtained with .6 m {Mr Moon / Mr Moore} /m ebonite and wood separators ribbed one side. This increase of electrolyte results in a lower temperature, decreases evaporation and frequency of topping up, and promotes a longer life. Having regard to the desirability of lowering the charging P.D., I consider we are justified in reverting to .4 m {Mr Moon / Mr Moore} /m ebonite in conjunction with the other modifications resulting in improved efficiency with only a remote possibility of failure of the thinner ebonite. Yours faithfully, J.S. Preston. FOR PRITCHETT & GOLD and E.P.S. | ||
