| Contd :- -2- It should be possible for the valve mechanism to be altered so that it is not operated directly from the bell cylinder, but indirectly by a spring loaded toggling mechanism (as in the Autovac.) We should be pleased to test any further samples of this tank in which the present faults have been remedied. Hs{Lord Ernest Hives - Chair}/A.J.Lidsey. | ||
