摘要： Apparatus and methods for delivery of air-borne materials from pulsatile delivery devices by passing the emissions from such devices and air in a coaxial manner through a suitable mixing chamber. Preferred apparatus include a chamber defining an axis of air flow, a plurality of pulsatile delivery devices, an actuator in communication with the devices for selective actuation thereof, and a device for introducing air at a first end of the chamber and for flowing that air substantially along the axis. The pulsatile delivery devices are positioned at the first end of the chamber such that actuation of the devices emits an air-borne substance substantially along the axis of air flow.

摘要： Apparatus and methods for accurate delivery of relatively small quantities of powdered solid materials. Preferred apparatus comprise: a primary chamber having a lateral surface extending between a first open end and a second open end; a rotating member that is positioned within the primary chamber and extends from a first position within the primary chamber to a second position within the primary chamber; a motor coupled with the rotating member and adapted to effect rotation thereof; a feed chamber having a lateral surface extending between a first open end and a second open end; and an air flow chamber coupled with the primary chamber and having a lateral surface extending between a first open end and a second open end.
