    摘要： A floor cleaning device comprises a base portion for movement along a surface and a handle portion pivotally connected to the base. The base portion further includes a suction nozzle and a brush assembly for agitating the surface, wherein the brush assembly and the nozzle assembly are in a first position raised off of the surface for vacuuming the surface, and the nozzle assembly is lowered to a second position contacting the surface for collecting and picking up liquid and dirt from the surface. A method of cleaning a surface by first dry vacuuming the surface using a cleaning unit in which the nozzle assembly is raised to pick up particles and then wet vacuuming the floor with the nozzle assembly lowered to collect and pick up dirt from the floor mixed with cleaning solution distributed on the floor.

    摘要： A recovery tank is provided for a floor cleaning unit. The recovery tank comprises an inlet opening and a duct fluidly connected to the inlet. The duct extends horizontally within the tank adjacent a side wall the recovery tank for directing air and liquid from the inlet opening in two opposing directions. A lid covers the tank and has an outlet opening for directing air out of the recovery tank. A pair of shields depends downwardly from the lid and extends from the duct to the side wall of the recovery tank. The outlet opening of the lid is located between the shields such that the shields prevent liquid from coming out of the duct and entering the outlet opening of the lid.

    摘要： A cleaning apparatus for cleaning a surface in which cleaning solution is dispensed to the surface and substantially simultaneously extracted along with the dirt on the surface in a continuous operation is provided. The cleaning apparatus includes a housing and a recovery tank removably mounted to the housing. A liquid distribution system is operatively associated with the housing for distributing the cleaning solution to the surface. A suction nozzle is secured to the housing and in fluid communication with the recovery tank. A suction source is in fluid communication with the suction nozzle for generating suction to draw dirt and liquid through the suction nozzle and into the recovery tank. The suction nozzle includes a front nozzle portion removably mounted to a rear nozzle portion.

    摘要： The present invention is a chromatic-emphasis hybrid-diatonic leverless keyboard configured to provide an extension, duplication, or representation of both heptatonic and pentatonic keys on the leverless keyboard. The extension enables the user to shift the physiological center of gravity for the keyboard to the area where pentatonic and heptatonic keys share space and are more isomorphic, thus assisting in gaining and applying understanding of the chromatic equality of the twelve tonalities in standard equal temperament, and in gaining and applying understanding of the one-dimensional nature of music.

    摘要： A cleaning apparatus for cleaning a surface in which cleaning solution is dispensed to the surface and substantially simultaneously extracted along with the dirt on the surface in a continuous operation is provided. The cleaning apparatus includes a base portion for movement along the surface and a handle pivotally connected to the base portion. A solution tank for supplying a flow of cleaning solution to the surface is removably mounted to one of the base portion and handle. A recovery tank is removably mounted to the handle. A suction nozzle is secured to the base portion. A suction source is located downstream of the recovery tank in fluid communication with the suction nozzle for generating suction to draw dirt and liquid through the suction nozzle and into the recovery tank. A suction conduit is fluidly connected between the recovery tank and the suction source. A suction shut off device is operatively connected to the suction source to shut shutoff suction through at least a portion of the suction conduit upon the handle being pivoted down a predetermined distance to a first position.
