Abstract: A concrete structure forming system includes a panel formed of a concrete material and a void former disposed on a section of the panel that is less than an entirety of the panel. The void former is monolithically formed in a single piece of a plastic material. The void former is removable from the panel in the single piece to leave a recess in the panel when the concrete material has reached a cured state.

Abstract: A portable cleaning container for use with a conventional mop and wringer for cleaning floors and other surfaces. The container includes a bucket with a drain opening formed through the bucket floor and closable by an elastomeric stopper supported on the end of a threaded drive rod extending through a threaded bore formed through a drive rod mount attached to the inside of the bucket within a stopper drive recess formed in the wall of the bucket and extending vertically from the floor of the bucket above the drain opening. A filter recess is formed in portions of the upper surface of the bucket floor to receive an interior filter having a planar portion that extends across the filter recess and a semitubular portion that extends about lower portions of the stopper drive recess to enclose the entrance of the drain opening to the bucket interior. Troughs in the planar portion of the interior filter and corrugations in the floor of the bucket adjacent the filter recess trap detritus when the bucket is drained.

Abstract: An improved portable cleaning station for use with a conventional mop device and wringer device to clean floors and other surfaces. The portable cleaning station comprises a bucket assembly for containing a cleaning solution and having a drain opening formed in its lowermost portion; a valve assembly supported by the bucket assembly so as to communicate with the drain opening and selectively opening and closing the drain opening; and a filter assembly supported by the bucket assembly, the filter assembly selectively movable between an extended position (wherein a filtering element is disposed below the valve assembly and in a filter relationship therewith) and a retracted position (wherein the filtering element is disposed in a protected position beneath the bucket assembly).
