YOUR REFERENCE: PLEASE QUOTE OUR REFERENCE: CDG/SK. Messrs. Rolls Royce Ltd., Derby. For the attention of Mr. West. Dear Sirs, As promised in our letter of 12th May, we enclose graphs shewing variation of the capacity of ignition condensers with temperature. You will observe the great effect of frequency upon the shape of the curves and we would be very interested to learn the frequency and method of test used by yourselves when preparing your blue print dated 8th April, which dealt with two of our condensers wound on a 3/16 spindle, which was subsequently with-drawn. Yours faithfully, THE TELEGRAPH CONDENSER COMPANY LIMITED. [Signature] ENC. The 3 samples which we sent you on the 12th May were the type wound on 1/4" diameter paxolin tube. | ||
