Abstract

537,455. Elastic-fluid turbines. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. April 12, 1940, No. 6628. Convention date, April 15, 1939. [Class 110 (iii)] Two or more blades 16 are formed integrally with a common root piece 15. A shrouding ring 24 is secured by riveting over integral pins 22, or, by filling holes such as the rivet holes 23 with weld material, or, by welding the edges of the blades to the underside of the shroud.
