Abstract: This invention relates to a safe cartridge for gas and intends that, when the cartridge has been overheated and the inner pressure has abnormally risen, let an invisible crack open in a suitable area of the cartridge to escape the inner gas gradually to reduce the inner pressure, without gushing out a large quantity of the gas in a moment, as in usual rupture discs, to prevent the flying of the cartridge by the force of reaction.

Abstract: A blade in the fan wheel of a diagonal-flow fan, which blade should ideally have the contoured shape of a twisted double-curvature or undevelopable surface, is formed from a portion of a plate which has a flat planar surface. To develope the flat blade shape from a planar surface, lines of intersection between a plate and the streamsurfaces in the ideal fan wheel, which are represented by a number of coaxial imaginary conical surfaces, are used as a basis for design. The realized flat blade can then be orientated between the frustoconical main and side plates to form a diagonal-flow path similar in performance to the ideal blade of a twisted double-curvature surface.
