| ROLLS-ROYCE LIMITED. INSTRUCTIONS. X 2572 A To: Mr Clark. Date: 27/10/19 Order No: — Customer's No.: — 2nd Sample G.E.C. Condenser. (Leaf connection) This condenser broke down on 220 AC Volts. On examination it will be found that the tin foil comes close up to the edge of the mica plates in our Corner. It does not appear to have any advantages over our own product as I have seen some of our own which are even thinner than the G.E.C. & are having to be packed up with mica to the necessary .40" thickness. The capacity of such condensers being about .21 M.f. Signed: [Illegible signature] This Sheet must be filed on completion of the work. RR 238 (300 Bks.) (SF 152. 6-11-18.) MP 197880 | ||
