Abstract: An orally inhalable formulation is provided comprising nicotine or a pharmaceutically acceptable salt thereof, a monohydric alcohol, menthol or a menthol-containing essential oil and a propellant. The formulation may be provided in a pressurized metered dose inhaler.

Abstract: The invention comprises a set of tubular inflatable bags mounted to the underside of a transport trailer along its lower edge in front of the rear wheel assembly. The bags are pressurized by ram air inflation upon forward motion of the trailer, such that they prevent air from entering the rear wheel assembly and thereby reduce aerodynamic drag. The outer exposed sides of the bags are vertically and horizontally straightened and stiffened by horizontal ribs which are anchored by cords to the trailer. The apparatus gives way without stress when unpressurized at slow speed and when docking to avoid damage.

Abstract: A flexible bag aerosol holding chamber is sealed around the outlet passage of the actuator for a pressurized metered-dose inhaler. An elastic-loaded mouthpiece is sealed around the inlet passage of the actuator so that the user may intermittently break the seal around the inlet passage by withdrawing the mouthpiece, thus allowing inhalation of a portion of the aerosol contents of the chamber. In a preferred embodiment the invention the aerosol contains a compound which has traditionally been smoked such as nicotine or a cannabinoid, The user may draw upon the chamber's contents a number of times at a frequency analogous to smoking until the chamber is fully collapsed. One inhaler actuation, and one filled chamber, are comparable to one cigarette. The collapsible bag chamber allows for economy of inhaler actuations relative to user inhalations, without the aerosol being diluted by ambient air.

Abstract: A twin bag inflatable rear airfoil for truck or transport trailer with attached shelves that bridge the surface gap between the trailer side and top surfaces, and the corresponding side and top surfaces of the inflatable bags. Shelves also bridge the upper surface gap between the two bags and provide a platform to deploy a collapsible yaw control fin. Another set of panels provide airfoil surfaces in the ground domain and are integral to the organised automatic folding and stowage of the apparatus. Interrupted ribs stiffen the inflatable surfaces while allowing them to fold in an orderly manner.
