The next step should be, we think, to have a number of regulators of this type, made up in the final form mounted together with the R.R. cutout on the R.R. base, and fitted on cars for road test. Before this can be done, however, there is still to be settled the question of mounting the three regulator resistance units in the back of the base. In this connection we recently reported that the makers objected to mounting these units on the front owing to their close proximity to the regulator, and the heat produced in them. Our views concerning this are:- (1) That it is inconsistent without some good reason to press the makers to reduce the heating effect on their regulators and then compel them to fit heat-producing units close to it. (2) It would be better for both regulator and cut-out, for the resistances to be mounted in the back of the base, and if possible, ventilated. (3) We think it should be done unless the cost involved is prohibited. Rm{William Robotham - Chief Engineer}/RC.{R. Childs} | ||
