Patent number: 6752148Abstract: 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.Type: GrantFiled: September 1, 2000Date of Patent: June 22, 2004Assignee: Delsys Pharmaceutical CompanyInventors: Joseph T.

Patent number: 6168666Abstract: Acoustic bead charger/dispenser employs a bead dispersion plate (BDP) to align beads with, for example, bead collection zones of a bead transporter chuck, then propel or launch them toward the bead collection zones, using acoustic energy provided by a speaker. The bead dispersion plate can be configured so that the acoustic energy from the speaker may be directed so as to impart to the bead translational kinetic energy primarily in a direction toward the bead collection zone of the bead transporter chuck. The bead dispersion plate can comprise a conductive surface that can be used to accelerate the beads toward the bead transporter chuck. Using sufficient acoustic energy applied by the speaker, sufficient translational kinetic energy can be imparted to beads to remove them from the conductive surface when they are under the influence of an electrostatic image force.Type: GrantFiled: May 22, 1998Date of Patent: January 2, 2001Assignee: Sarnoff CorporationInventor: Hoi Cheong Sun
