| RR 238 (180 BKS.) (DB{Donald Bastow - Suspensions} 461-8-12-24) MP 306975 ROLLS-ROYCE LTD. INSTRUCTIONS. X3830 To E.F.G. 7 - 6 - 1926 Order No. J.B. 33 Customer's No. X3830 Re examination of Tungstone Cell. This cell appears to be of a similar construction to the first cell received only that the plates are built up in sections of 6 instead of 4 as in the previous one, this making the cell taller & increasing its capacity to a rated 75 ampere hour. In the positive grid a method similar to our present standard is used for effectively keying in the paste. Two of the negative plates are loose in their sockets these not being effectively keyed in. This trouble was experienced in the previous cell. Signed Front S! This Sheet must be filed on completion of the work. | ||
