Abstract

355,759. Steam &c. turbines. RATEAU, L. A. J., NOBLEMAIRE, M. A. G. MARGOT-, and RATEAU, A. J. A., 10 bis, Avenue ElisÚe Reclus, Paris. Feb. 19, 1930, No. 5614. Convention date, Feb. 19, 1929. Void [Published under Sect. 91 of the Acts]. [Class 110 (iii).] Blades, fixing.-The root of a turbine blade a is formed in two parts c, c<1> having lateral surfaces in radial planes. The widtl of the part c<1> nearer the centre is less than the width of the part c, and the thickness of the rotoi at b<1> in the region of the part c<1> is greater than the thickness in the region of the part c. Two rows of rivets d, d<1> are used For long blades the root! have several sections c, g, h, Fig. 3, and four rows of rivets d, i, d<1>, il are used. It is stated that the arrangement may be reversed.
