...that several people are credited with the invention of the flush toilet? Most people have heard of Thomas Crapper (1837-1910), the sanitary engineer who invented the valve-and-siphon arrangement that made the modern toilet possible. Another claimant to "the throne" was British inventor Alexander Cumming who patented a toilet in 1775. Then there's a nameless Minoan (a native of ancient Crete) who lived 4,000 years ago who supposedly was ahead of his time and created the first flush toilet!

AbstractA disposable package, tape, and cassette are provided which makes it possible to hold and disperse therefrom liquid, flowable formulations including aqueous formulations (solutions or dispersions with particles less than 0.25 microns in diameter) of a pharmaceutically active drug. In one embodiment formulation is packaged in individual dosage unit containers which containers are preferably interconnected. The package is designed to be integrated into a cassette which can be loaded into a dispersing device capable of individually opening dosage unit containers and aerosolizing the contents through a porous membrane, into a mouth piece on the cassette, for delivery to a patient. In addition to and alongside of each porous membrane, the package may include one or more openings through which air is forced in order to aid in avoiding the accumulation of aerosolized particles. The package may be configured so that the formulation is held in a container not positioned directly vertical to and below the porous membrane, thus making it necessary to channel formulation horizontally to the porous membrane and making it possible to include a vibrating mechanism directly below a chamber covered by the porous membrane. Release of aerosolized drug is breath actuated based on simultaneous measurements of inspiratory flow and volume so as to provide for repeatable dosing of drug to the patient.Other References
