| X4508 To Hs{Lord Ernest Hives - Chair}/Std. Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson}3/KW.21.11.34. We want you to make a study of bi-metal thermostats in relation to hot spot control. There is a bi-metal thermostat fitted on the automatic starting choke on the Buick and the La{L. A. Archer} Salle, and also we believe on the Terraplane. The Buick and La{L. A. Archer} Salle also have a thermostat exhaust hot spot regulation bi-thermostat. We have ordered a copy of "Thermostats" by Roosevelt Griffiths, which is the latest work on the subject. We attach a catalogue of Mr. Miller, Nansen Road, Sparkhill, Birmingham, who makes bi-metal thermostat strips. We should like you, in conjunction with the laboratory, to obtain all sorts of bi-metal strips, and make up some working models to demonstrate what they will do. We should like you to get what particulars you can of the butterfly valves and spindles fitted to the exhaust heated hot spots in American cars, and get one rigged up on one of our Experimental cars, even though the exhaust heat is not used for any purpose, and keep it running about under observation. We could also give one an endurance test at very high temperatures on the test bed. We should like you to look over N.Sch's 4238, 4244 and 4238, and see if full advantage has been taken of the latest radiator design to lighten the matrix.
