Abstract: 206,524. Akt.-Ges. Brown, Boveri, et Cie., (Assignees of Forner, G.). Nov. 6, 1922, [Convention date]. Drawings to Specification. Axial-flow type.-In an impulse turbine stage in which the initial steam velocity is equal to or greater than the velocity of sound, the blades are constructed so as to provide a slight re-action effect in those later rings of blades in which the relative entrance velocity of the steam has fallen below the velocity of sound. The re-action effect is in amount such as not to increase the relative exit velocity beyond the velocity of sound and the blades are designed to secure that the increments of kinetic energy in the blade rings are in inverse ratio to the relative entrance velocities. The Specification as open to inspection under Sect.. 91 (3) (a) comprises also the statement that the axial component of the steam velocity is maintained approximately equal in all the blade rings. This subject-matter does not appear in the Specification as accepted.
