Abstract

374,783. Steam turbines. AKT.- GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. Dec. 4, 1931, No. 33713. Convention date, Dec. 4, 1930. Addition to 368,578. Drawings to Specification. [Class 110 (iii).] In a turbine having end-thrust balancing means as described in the parent Specification the shrouding of some or all of the blading is formed with extensions forming sealing means which open and close in the same sense as the sealing means of the dummy piston.
