Abstract: The present disclosure is directed to cleaning machines and methods of use to clean flooring and other surfaces. One configuration is directed to a cleaning machine that utilizes a motor to drive an interchangeable cleaning drum about a rotational axis parallel to the surface being cleaned. The cleaning machine can be operable to clean a surface, such as a flooring surface or other surface (e.g., walls, ceilings, etc.) without a vacuum, pump, solution tank, or recovery tank. The cleaning machine may contact the surface being cleaned at replaceable glides disposed at or near a distal end of a cleaning head of the cleaning machine.

Abstract: An improved light modulating material for use in electro-optic and thermo-optic display devices is produced by forming a homogeneous solution comprising an acrylic resin containing active hydrogen groups, a liquid crystal material, a diisocyanate or epoxide, and a solvent. The homogeneous solution is preferably applied to a conductive substrate and the solvent is then evaporated, causing phase separation resulting in formation of a liquid crystal phase dispersed within a solid polymer matrix. Application of an electric field to the substrate causes the liquid crystal material to align, which in turn causes the coating to switch from substantially translucent to substantially transparent. If the electric field is removed the light modulating material again becomes substantially translucent. Switching times can be improved by incorporating a titanate or zirconate organometallic material into the light modulating material.
