Abstract

214,985. Erste Br³nner Maschinen- Fabriks-Ges. April 25, 1923, [Convention date]. Axial-flow type; casings; blades.-The shrouding d covers part only of the width of thei blades and extends forwards to form a sealing gap s. The shrouding may be flanged at t. The casing diverges as shown. In the Specification as open to inspection under Sect. 91 (3) (a) it is stated that the angle of divergence a is preferably equal to Mach's angle. This subject-matter does not appear in the Specification as accepted.
