Abstract: An inhaler disc cartridge comprises a carrier disc with radially outwardly extending resilient fingers, each with a medicament powder dosage. A sealing disc and an indexing ring are bonded to the disc. A cam sequentially and manually deflects a selected finger causing it to snap against an anvil to release the dosage by momentum energy transfer. In other embodiments, a cassette includes a carrier substrate reel of deposited powder dosages with a dosage sealing tape. The substrate comprises a belt with a plurality of transversely extending triangular fingers, each finger tip with a dosage thereon. Each finger is snapped in sequence against an anvil while a clamp secures the belt as the fingers are deflected. The spring fingers are corrugated in one embodiment cooperating with an anvil having channels and a device for inducing agglomeration breakup air streams through the channels.

Abstract: The disclosure relates to an apparatus for electrostatically adhering grains to a planar substrate comprising: a. an electrostatic chuck having a collection surface with at least one grain collection zone for, when the planar substrate is layered on the collection surface, electrostatically directing charged grains to a corresponding surface on the planar substrate; and b. a pattern of holes through the electrostatic chuck allowing a source of low pressure to act through the electrostatic chuck to adhere the planar substrate.

Abstract: Provided is, among other things, and together with associated methods, a powder feed comprising: a venturi comprising an external gas inlet, a gas outlet through which gas flows at a rate amplified over a gas flow rate into the external gas inlet, and an internal gas inlet; and a cyclone with an intake port connected to the venturi gas outlet, a recycle outlet port, and a product port, wherein a gas flow rate FS into the venturi external gas inlet results in an enhanced flow rate into the cyclone intake port.

Abstract: A jaw is secured to a stem member having a T-shaped slot through which a pair of spaced pins pass. When the jaw and member are displaced from a clamp position to a neutral position, one of the pins is aligned with the T portion of the slot and the other pin is seated at one end of the main slot. The member tilts automatically to a retracted state in response to a spring force in a given direction. When the member is rotated from the retracted state to the neutral position the same spring force slides the jaw into the clamp position. A resilient projection on the stem member automatically engages a workpiece when the member reaches the neutral position to locate the workpiece prior to clamping.

Abstract: A first measuring contact is displaced along a gauge distance measuring axis to measure the distance to a second reference contact. Both contacts pivot about axes that lie on the gauge measuring axis and on the respective contact surfaces. When the contacts abut, the pivot axes are coextensive. Both contacts can engage a contoured wall regardless its angle to the gauge measuring axis and accurately measure the wall thickness along the gauge measuring axis.
