| -7- THERMOSTATS. They have developed an entirely new method of making these, samples of which I am bringing back. They cost 25 cents each. Buick's use a single thermostat valve and a spring loaded by-pass which opens by the water pressure when the thermostat closes. It is somewhat ironical that the BOO(?) car alone can afford to support a research organisation such as the Harrison Corporation; it is more distrubing to realise that Cadillacs are fortunate enough to have these facilities at their disposal. I will let you have something about Pratt & Witneys when I have time. Saunders believes the water-cooled engine will come again as a pressure steam cooled, 50 lbs. per square inch; power thus generated used to drive auxiliaries before passing to condensers at atmospheric. This sounds somewhat futuristic. I hope that when I get back we may be able to arrange for one competent person to be allotted to each specific chassis component, and in the re-arrangement of the shop find room for these people to sit down and think, momentarily at any rate. Now we are running three chassis we must be able to afford this. RM.{William Robotham - Chief Engineer} | ||
