Title: Powder inhaler
Inventor: JOHN PINON
IPC: A61M15/00
Filed: 2003-07-22
Granted: 2006-12-12
Abstract: A powder inhaler comprises a container for storing a powdered medicament, a metering member having a dosing recess to be filled with a dose of the powdered medicament, and a mouthpiece being in communication with an inhalation channel of the powder inhaler. Furthermore, the powder inhaler comprises a protective member which is slidingly moveable on the metering member between a closed position, in which it at least covers the dosing recess of the metering member thereby enabling inhalation of the dose of the powdered medicament contained in the dosing recess The protective member is preferably coupled to an inhalation actuated mechanism in such a manner that the inhalation actuated mechanism moves the protective member from its closed position to its open position only if there is an inhalation suction force exerted by a user which exceeds a predetermined level. This prevents the dose contained in the dosing recess from falling out of the dosing recess, unless there is no inhalation process initiated by the user. Therefore, the powder inhaler can also be operated reliably upside down. Furthermore, a deagglomerator arrangement (cyclone), which may be incorporated in such a powder inhaler, is proposed which comprises a vortex chamber having a diameter between 6 mm and 8 mm, preferably 8 mm.

Title: Infrared optical fiber
Inventor: SAKURAGI SHIRO
IPC: G02B6/02
Filed: 1981-07-11
Granted: 1984-12-31
Abstract: Infrared optical fiber core is made up of one component of halogenides (i.e. TlBr, TlCl, AgBr, AgCl, CsI, CsBr) and a slight amount of additive, which contains the anion or cation of the halogenides. Because the additive inhibits the slipping of crystallites, the mechanical strength and elastic region of the core increase. This reduces roughing of the surface by plastic deformation. Additionally, because the growth of crystallites is restrained by the additive, the characteristics of transmission remain stable for a long time.
