    摘要: An upright vacuum cleaner having dual cleaning motor and fan units is provided having a cleaning head engagable with a floor and a suction nozzle and a brush roller rotatably mounted therein. A first motor and fan unit is mounted in the vacuum cleaner for producing suction in the suction nozzle and is operatively connected to the brush roller for rotating it. An upright housing is connected to the cleaning head, the housing having a handle for moving the vacuum cleaner along the floor during floor cleaning use. Contained in the housing are a dirt storage container, a passageway leading from the suction nozzle in the cleaning head to the storage container and a second motor and fan unit operatively associated with the storage container for drawing dirt laden air from the cleaning head through the passageway and into the storage container simultaneously with operation of the first motor and fan unit.

    摘要: A book rack has two side walls and a rack extending between the side walls. The side walls each include a core made of a lightweight structural material, such as corrugated or honeycombed paperboard, a coating which coverers inner and outer surfaces of the core, and an edge bead covering an edge of the core. The rack comprises a single sheet of substantially transparent material formed generally as a wave defining a plurality of valleys. Each valley has a forward wall and a rear wall. The sheet is formed such that the a valley is positioned above and behind a preceding valley so that the books which are placed in the valleys will be easily visible.
