Abstract: A composite component, such as an aerofoil component for a gas turbine engine, comprises a body and a platform which are formed from respective body and platform preforms. The body preform includes fibers which are directed laterally of the preform, forming a cavity in the end of the preform. The platform preform includes a projection constituting a deltoid filler which is received in the cavity. The projection includes a 3D woven structure of reinforcement fibers so that the cavity is occupied by fibers to give the platform a generally uniform volume fraction. A further platform preform fits over the body preform so that the lateral fibers are sandwiched between the platform preforms.

Abstract: A unit dose dry powder inhaler has a dispersion chamber, optionally including one or more beads. A blister is supported adjacent to the dispersion chamber. A mouthpiece cover is removable from a mouthpiece, with movement of the mouthpiece cover causing the blister to open. An air flow path extends past or under the blister and into the dispersion chamber. As a result, the blister remains sealed until the inhaler is ready for use. The blister is then automatically opened when the mouthpiece cover is removed from the mouthpiece. Pharmaceutical dry powder is released from the blister and entrained in air flow through the inhaler, when the user inhales on the mouthpiece. The powder is dispersed in air within the dispersion chamber.

Abstract: A dry powder inhaler for providing multiple doses of a pharmaceutical powder from blisters on a blister disk includes an actuator pivotably mounted on a base. Movement of the actuator from a first position to a second position drives the a dobber to open a blister. A tray retainer is moveable between opened and closed positions, and the actuator is moveable to a position at least partially overlying the tray retainer, when the tray retainer is in the closed position. A dispersion engine sub-assembly has a blister hood positioned over a blister opening position. A powder pathway connects from the blister hood into a powder dispersion engine. Upon inhalation, air flow draws powder up and out of an opened blister, into the blister hood and to the powder dispersion engine. Movement of the actuator causes the dobber to shear open a blister on a blister disk, and also to press the blister hood down over, or into contact with blister disk.
