HS{Lord Ernest Hives - Chair}2/LG23/4/20 - With reference to the thermostat control of water circulation, we quite expected that when the thermostat was closed that the water circulation would be reduced. The advantage we obtained by allowing this [word struck through] was that the bypass valves and pipes were much smaller and lighter. We are pleased to hear that when the thermostat valve was open for circulation through the radiator, the rate of flow is not materially altered. When the drawings for these are corrected, (the rubber connection between the thermostat tower and the other top pipes of the water system) I should be glad if you would arrange for copies to be sent to Mr. Olley and Mr. J.C.Royce in America.
