It followed that a difference in the number of stages of pressure was no indication of independence of type, a conclusion which seemed to be correct, for such differences were not the result of differences in fundamental principles of construction. If, for a turbine of given power, one of the three types was decided upon, and the speed and the minimum degree of efficiency were fixed, then the number of stages was absolutely fixed. Thus, the turbines of De Laval with one, of Zolly with about twelve, and of Bateau with about twentyfour, stages of pressure belonged to the same type, namely, impulse turbines; while the turbines of Riedler-Stumpf with one, of Curtis with two or three, and the Elektra with four or five velocitystages, belonged to the second type. The third main type was represented by the Parsons turbine. Even a combination of these types in one turbine, as recently carried out by, among others, Messrs. Sulzer Brothers, of Winterthur, and by the Union Actien-Prof. Banki. Gesellschaft, of Essen, did not form a separate type; nor could the utilization of part of the expansion of the steam in subsequent stages in pressure turbines be considered to constitute an independent type.
