MRS A.S.G. BROWN. W.J. COLE, (MANAGING) Wales Farm Road, North Acton, London, W.3. 17th January 1934 YOUR REF Hs{Lord Ernest Hives - Chair}/Wst/9.MA OUR REF HWC/DS Messrs Rolls Royce Ltd., D E R B Y WST Dear Sirs, With reference to yours of the 16th January we would firstly say how pleased we are to note that the condensers are continuing to prove satisfactory. We also thank you for the order you are sending us for six more condensers which we trust we may invoice to you in due course. The condenser you are using incorporates the high capacity impregnant of which you speak and the size is therefore the smallest that can be put forward consistent with a reasonable thickness paper dielectric. The German practice is of interest but has a serious objection in that hot oil is very difficult to keep within bounds, and should it leak out then there is trouble. The condenser we have supplied to you, we think we are right in saying, will be worked up to but not exceeding 80°C and if this is so the question of melting and solidifying the impregnant does not arise, and the Bosch development is unnecessary. We trust that the foregoing remarks will prove interesting, and remain, Yours faithfully, THE TELEGRAPH CONDENSER CO. LTD.
