Abstract

742,288. Gas turbines. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. Feb. 15, 1952 [Feb. 15, 1951], No. 5914/54. Divided out of 742,241. Drawings to Specification. Class 110(3) The shroud rings for a row of rotor or stator blades is formed by integral blade platforms in the adjacent row of stator or rotor blades, the platforms being spaced from the stator or rotor, and the blades are supplied with a coolant. The subjectmatter is identical with that described in Specification 742,241 but the claims differ.
