Abstract
533,000. Elastic fluid turbine. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 2, 1939, No. 26996. Convention date, Oct. 1, 1938. [Class 110 (iii)] Turbine blade roots and the axial reception slots in the rotor are V-shaped and one face of each root and slot have serrations, or other devices, which cause the blade under the action of centrifugal force to tend to move towards the other plane face of the rotor slot and to set itself thereon firmly. The base angle C of the serrations is less than a right-angle and more than the inclination B of the opposite plane surface 18. The serrations may be on a radially inclined surface and opposed to a radial plane surface.
