| E.F.G. J.D.112 X8839. 29-1-21. X 3839 Threaded Rubber Separators Tests have now been completed on Threaded Rubber type of separation for accumulators. The general results & conclusions arrived at are reported below. 3 Batteries were made up comprising of Peto & Radford Std. cells with wood & ebonite separators. Peto & Radford cells with Threaded Rubber separators. 3 having the ribs towards the positive plates & 3 having the flat side towards the positive plates. Exide Std. cells with wood & ebonite separators Exide cells with Threaded Rubber separators all the ribs facing the positive plates. The Threaded Rubber separators become very brittle after a few (contd) | ||
