Patent number: 10188823Abstract: A drug delivery system, which includes an aerosol generator unit, a pumping unit, a flow tube, at least one condensate collector and an aerosol transition adapter. The aerosol generator forms an aerosol from a liquid formulation, which is partially volatilized. The pumping unit supplies the liquid formulation to the aerosol generator unit and a flow tube having an inlet end in fluid communication with an outlet of the aerosol generator unit and an outlet adapted for connection to a patient interface, which supplies ventilation gas to a patient's lungs. The system also includes at least one condensate collector adapted to collect condensed liquid or liquid produced by the aerosol generator unit, and a transition adapter arranged to mix aerosol produced by the aerosol generator unit with heated air or ventilation gas and direct the mixed aerosol into the inlet end of the flow passage.Type: GrantFiled: July 23, 2012Date of Patent: January 29, 2019Assignee: Philip Morris USA Inc.Inventors: Sudarsan Srinivasan, David Ammann, Donald Brookman, Niranjan Maharajh, Gary Grollimund, F.

Publication number: 20140165999Abstract: An aerosol generation system having an aerosol generator wherein a liquid formulation is at least partially volatilized in a capillary passage and discharged from the capillary passage to form an aerosol. The aerosol generation system includes a pumping unit adapted to supply a liquid formulation to the aerosol generator; and a fluidic element located between the pumping unit and the capillary passage of the aerosol generator, wherein the fluidic element increases backpressure of the liquid formulation as the liquid formulation enters the capillary passage of the aerosol generator.Type: ApplicationFiled: December 26, 2013Publication date: June 19, 2014Applicant: Philip Morris USA Inc.Inventors: Niranjan Maharajh, Gene Faison, Sudarsan Srinivasan, David Ammann, Donald Brookman, Amit Limaye, Ronald Formosa

Patent number: 4753172Abstract: The projectiles possess high kinetic energy owing to the high velocity of the projectiles, on the one hand, and the high specific weight of the projectiles, on the other hand. The heretofore normally employed explosive and incendiary charges are replaced by an inert powder serving as the projectile filling or filler and having a density of at least 10 g/cm.sup.3 and whose constituents have a mass of 10.sup.-4 to 10.sup.-2 grams. Certain constructions of the projectiles contain a fragmentation jacket, the filling or filler, a closure body or penetrator and a projectile tip. Another construction of the projectile contains a fragmentation jacket, the filling or filler, an integrated base for the fragmentation jacket and the projectile tip.Type: GrantFiled: March 16, 1987Date of Patent: June 28, 1988Assignee: Werkzeugmaschinenfabrik Oerlikon-Buhrle AGInventors: Harald Katzmann, David Ammann, Pierre H. Freymond, Hanspeter Sigg

Patent number: 4690029Abstract: Up to now exceedingly precise manufacturing tolerances had to be observed in securing or mounting a flare composition or incandescent charge sleeve in a blind borehole in the tail portion of a projectile body to ensure reliable sealing against propellant gases. To prevent this disadvantage a bolt member or plug is inserted into the blind borehole of the projectile body until the face or end surface of this bolt member or plug abuts the bottom region or portion of the blind borehole. The bolt member or plug and the projectile body are rotated relative to one another. Due to friction between the end surface of the bolt member or plug and the bottom portion of the blind borehole sufficient heat is generated at the front end of the bolt member or plug such that material of this front end of the bolt member or plug flows into an annular groove of the blind borehole to form a flange member. This flange member securely anchors the bolt member or plug in the blind borehole.Type: GrantFiled: December 9, 1986Date of Patent: September 1, 1987Assignee: Werkzeugmaschinenfabrik Oerlikon-Buhrle AGInventors: Harald Katzmann, Werner Senn, David Ammann
