Hello All,
            Some more ruminations following my "dream" for a valved
airblast gap this morning:

simply, a disc with holes positioned around the periphery to rotate
above a static gap so that an interrupted airblast could be fed in a
timed manner at the gap. Also opens the possiblity of phasing the
blasts using John Freau's rotary phasing circuitry. There are several
variations on this theme which spring to mind.
