| EFC. X7535P BY4/G.4.11.29. CELL CONNECTIONS. ------------ The linear expansion of ebonite from which the containers are made has a very much higher coeff. of expansion than lead, this being so it is not reasonable to expect cells which are being heated up during running and cooling down each night to stand up to solid connections. We have a robust case, and must have flexible connections. I do not propose to change our practice which is fairly free from trouble. BY.{R.W. Bailey - Chief Engineer} By | ||
