| To Mr. Valentine. 1290 Rm {William Robotham - Chief Engineer} /RC. {R. Childs} 19/JH.22.12.37. EXPERIMENTAL DEPARTMENT COLD CHAMBER. We should be obliged if you would obtain confirmation from Messrs. Hall Ltd. that it would be alright to run the fan continuous-ly while the rest of the plant is running on the automatic. The reason of the enquiry is "can we circulate the air more in the chamber when a car is being frozen down, as our plant being large and very efficient for the chamber size is constantly cutting in and out at a very small temperature variation.
