There is disclosed an aerosol delivery device. The aerosol delivery device includes a first aerosol first aerosol sized for pulmonary penetration; and a second aerosol sized to inhibit pulmonary penetration. The second aerosol is transmissible within at least one of: a mammalian oral cavity and a mammalian nasal cavity, and the second aerosol comprising an active component for activating at least one of: one or more taste receptors in said oral cavity and one or more olfactory receptors in said nasal cavity. The second aerosol generator includes a Venturi aperture to generate the second aerosol. There is disclosed a consumable for a substitute smoking device and a substitute smoking system. The consumable includes an airflow passage between an upstream inlet of the consumable and a downstream outlet of the consumable. The consumable also includes a porous member for passive aerosol generation. The airflow passage is constricted by the porous member to form a narrowed portion of the airflow passage. In another embodiment, the consumable also includes an inner porous member (315) for passive aerosol generation. The airflow passage has an annular portion surrounding at least a portion of the porous member. In another embodiment, a portion of the airflow passage is located between a porous surface of the porous member and an opposing airflow passage wall. A minimum distance between the porous surface of the porous member and the opposing airflow passage wall is less than 1000 microns. In another embodiment, the consumable also includes a porous member (315) for passive aerosol generation located within the airflow passage. The porous member is tapered along a longitudinal axis of the consumable. In another embodiment, the consumable has a longitudinal axis and includes an airflow passage (308) between an upstream inlet of the consumable and a downstream outlet of the consumable. The consumable also includes a porous member (315) for passive aerosol generation. A longitudinal cross section of the airflow passage includes an inclined portion forming a passage angle with the longitudinal axis of the consumable. The passage angle is greater than zero degrees and less than 90 degrees and a wall of the inclined portion is formed from a porous surface (318) of the porous member.

A splash plate assembly is retained in a rotary bell cup by a barbed skirt that interfaces with an inner surface of the bell cup. The splash plate assembly includes a splash plate or deflector that is secured to the front side of an insert. The insert has barbed extensions that may form a skirt around an outer periphery thereof. The insert is snapped into the front bell opening of a bell cup, and the barbed extensions elastically deform and snap back outwardly to interface with a shoulder formed in the bell cup inner surface.

A coating apparatus is disclosed for applying an activated coating onto an internal surface of a conduit, the coating being activated by mixing at least a first and a second component. The apparatus includes a high-pressure mix gun for mixing the at least first and second components such that the activated coating is generated. A rotary atomizer is operatively connected to and cooperates with the high pressure mix gun for receiving the activated coating from the high pressure mix gun. The rotary atomizer cooperates with the activated coating such that the activated coating is atomized so that application of the atomized activated coating onto the internal surface of the conduit is permitted.
