Abstract: A portable attachment for tank-type vacuum cleaners is provided which permits pickup of liquids as well as solids with the aspirated air. The attachment comprises a portable container having a removable cover thereon which makes a substantially air-tight connection with the container. A pair of nozzles are provided on the cover for fluid flow communication between the inside and outside of the container. One of the nozzles is adapted to have the suction hose of a tank-type vacuum attached thereto, while a scavenger hose for conveying a mixture of air, dirt particles, and liquid to the container is attached to the other nozzle. Valve means in combination with the first nozzle is spring biased in the closed position so that fluid flow communication between the inside of the container and the suction hose of the vacuum cleaner is established only when the valve means is activated to its open position.

Abstract: A paper tray assembly for paper reproduction systems comprising a flat base, an upwardly extending backwall, paper guides and guide strips. Rectangular recesses are located in the corners of the base adjacent the backwall and coinciding recesses are found in the backwall. Longitudinal slots are contained in the rectangular recesses parallel the backwall. A paper guide is provided having floor, sidewall and endwall portions adapted to fit in the recesses. Transverse guide strips extend over the floor of the paper guide and across the base. The floor of said paper guides and said guide strips contain apertures which are in alignment with longitudinal slots. Fastening means are provided to fit through said apertures and slots thereby securing the paper guide and transverse guide strips in any desired position along the length of the longitudinal slot.
