The presence of oil here may be detrimental to the functioning of the condenser, as it relies on this surface for the earth return. (4) We consider that the inner end of the L.T. terminal, which is only 3.B.A. should be a little more robust, two of these have been broken during the tests. (5) The spring tension required on the contact points to prevent flinging at high speed is 16 oz. We can only just obtain this on the springs supplied. We recommend a spring tension of 16 - 17 ozs. (6) The position of the lubricator has been criticised on the test bed in that the oil runs out instead of filling the well. RM{William Robotham - Chief Engineer}/HC. | ||
