| To Da. {Bernard Day - Chassis Design} From Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} 8235. Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} 4/KT. 24. 6. 31. HYDRAULIC SHOCK ABSORBERS. If you are doing anything further with the sylphon tube type of remote control for the shock absorber valves, will you please note that we find it necessary to incorporate some sort of accurate location for the sylphon tube, as otherwise the internal bore of the sylphon, which we use as a dash pot for the valve head, does not come concentric with the valve guide.
