The present invention comprises novel preparations of polyoxypropylenepolyoxyethylene copolymers which retain the therapeutic activity of the commercial preparations, but are substantially free from the undesirable effects which are inherent in the prior art preparations. The ion gate and ion modifier are combined so the ion gate is one of the ion modifier electrodes. Extension data are also recorded on this sole track along with the two-track data in the DV format. Specifically, an interconnecting member continuously interconnects for common rotation the carrier member of the first planetary gear set, the sun gear member of the second planetary gear set and the ring gear member of the third planetary gear set. There is also provided a fluid storage device, the fluid storage device being associated with a spray action to spray the fluid into the cabinet after the ozone has been circulated. Heat is transferred out of the imaging device assembly through a printed circuit board to which the assembly housing is mounted thereon andor through the housing itself.
