Abstract: A wet pickup attachment for vacuum cleaners has a pair of independent float operated valves to close primary and secondary exhaust openings responsive to different water levels in a collection tank and thereby prevent aspiration of water into a vacuum cleaner that powers the attachment.

Abstract: An aerator for attachment to a container for live fish. The aerator includes a one-piece molded plastic housing. The housing includes a lid portion, a body portion and a hinge portion pivotally connecting together the lid portion and the body portion. The body portion has a space for an operating battery and a storage space for a space battery. A first latch portion is attached to a body portion. An attachment device is molded into the lid portion of the housing. The attachment device defines a second latch portion which cooperates with the first latch portion to releasably secure the lid portion in a closed position relative to the body portion. The aerator includes a pump and a motor operably connected to the pump. The pump and motor are attached to the lid portion of the housing and electrical connection with the working battery is completed when the lid portion is pivoted to the closed position relative to the body portion.

Abstract: An air valve for controlling the supply of air to a venturi jet of a spa includes a housing, a cylindrical barrel, means for sealing between the housing and the barrel, and means for rotating the barrel. The housing has an interior chamber extending between an open, cylindrical bore at one end and a pipe coupling at the other end. The housing mounts on the inside wall of the spa, with the open end of the bore facing the inside of the spa and the rest of the housing extending through the side wall and positioned outside the spa. The cylindrical barrel is insertable into and rotatably mounted within the cylindrical bore of the housing. The housing and barrel each include ports that, when overlapping, provide a path for air to flow from a point exterior of the housing, through the overlapping ports, through the interior of the barrel and housing to the pipe coupling. Rotating the barrel to a position where the ports do not overlap blocks the air flow path.
