Dear Sirs, In answer to your letter of the 26th.instant, reference RM{William Robotham - Chief Engineer}/RC.{R. Childs}6/JH, concerning the Control Box unit for the Bentley three experimental models. We were under the impression that it had been definitely decided to fit these two Control Boxes on to the Bentley Experimental Cars exactly as they were delivered to you, but with one exception, namely, we were to have them returned here in order to fit the LR{Mr Ellor}7 Regulator with the 3:1 ratio which we have arranged to do, the Regulators now being ready awaiting the return of the boxes. We are of course quite in agreement with the fact that the resistances should be underneath the base, and we are designing a base which will be so arranged as to accomodate the resistance in that position. At the same time we informed Mr.Davis that we are quite satisfied with the two sample regulators, and that they would work perfectly satisfactory provided air holes are pierced in the cover to dissipate the heat. It was also understood that time was of importance, these experimental cars being scheduled to be on the road for testing in a few days time. Concerning your comments in the third paragraph of your letter re series winding on the regulator ended in Terminal "A" and not "A1". If this is actually so, it is an error which has been over-looked and which of course we shall correct on receiving the Control Box back; this was also put right - the comments of your last paragraph regarding the three turn tapping which has been brought | ||
