| - 2 - Messrs. Rolls-Royce Limited. Regarding the thermograph which we promised to lent to you for investigation work, we regret that we have not an instrument made up which has two recording pens. We shall, however, be very pleased to let you the instrument which Mr. Leslie saw which has one pen and is scaled 100/212°F. {Mr Friese} The length of capillary tube is 14 ft. and the dimensions of the phial are as follows:- Diameter 17/32" Overall length 7½" If this will be of any use to you we will check its calibration and send it complete to you, together with the necessary charts, ink etc. We have now received the three radiator thermostats which were discussed and are investigating the possibility of modifying the loads to suit your conditions. We will write to you on this point very shortly. Yours truly, THE PACKLESS GLAND CO. LTD. W. Martin-Hurst. Director. DRG. NO. BG. 775C. ENCLOSED. | ||
