A dry powder inhaler, including a powder dispersion engine with one or more beads in a dispersion chamber, an airflow path leading into the dispersion chamber, an elongated tape with spaced apart blisters, each blister holding a dose of a dry powder, and blister opening mechanism that sequentially opens the blisters on the elongated tape and releases the dose of each blister into the airflow path.

Breath actuated dry powder inhaler and tape dose strip

A dry powder inhaler, including a housing having an airflow path leading from an inlet, past a powder release location, to a mouthpiece; a drive spool engaged with a capstan adjacent to the powder release location; a spring biasing a ratchet into engagement with the drive spool; and a breath trigger in the airflow path. The breath trigger is moveable from a first position, wherein the breath trigger holds the ratchet, to a second position, wherein the breath trigger releases the ratchet to allow the ratchet to turn the drive spool.

A method for operating a dry powder inhaler, the dry powder inhaler having a dose tape having spaced apart doses of a powder pharmaceutical, each dose being in a respective sealed blister. The inhaler includes a breath actuated blister opening system that sequentially opens a blister on the tape. The method involves routing the dose tape between first and second rotating elements; spring biasing the first rotating element to turn in a first direction; holding the first rotating element from rotating against the spring biasing; and releasing the first rotating element, and allowing it to rotate a fraction of one rotation, when air flows adjacent to the first rotating element.

A dose tape for use in a dry powder inhaler has blisters formed in a formpack layer. A lidstock layer is attached over the formpack layer, to seal a dose of dry powder within each of the blisters. A tear strip is attached to the lidstock layer over each of the blisters. Pulling on the tear strip shears out an area of the lidstock over the blister, unsealing the powder contents.

A lift-off hinge assembly including a first hinge leaf hingedly connected to a second hinge leaf, the hinge connection between the hinge leaves being defined by at least two hinge formations spaced apart along the pivot axis of the hinge assembly, each hinge formation including a hinge pin positioned on one hinge leaf and which is journalled in the other hinge leaf, the hinge pins of all the hinge formations being arranged to cooperate with their respective journal to enable the hinge pins to be simultaneously withdrawn from their respective journals by moving the hinge leaves apart along the pivot axis, the journal for each pin being defined by a continuously walled aperture in an arm formed on the hinge leaf.

Lift-off hinge assembly

A hinge comprising a pair of hinge leaves pivotally connected together by a hinge pin, at least one leaf carrying a mounting bracket secured thereto by a single screw-threaded fixing, the fixing having a frusto-conical bearing surface which engages upon a corresponding frusto-conical surfaces on the leaf or bracket.

Mounting of vehicle doors

The seat has a cushion portion and a back portion connected thereto by a pivot. The back portion is rotated relative to the cushion portion about the pivot by a flexible threaded tube rotatably attached to the frame of the cushion portion and passing through a threaded member on the back portion. Rotation of the tube by means of a hand wheel, or an electric motor, drives the threaded member. The thread is selected to be self-locking.
