Abstract: A portable and foldable wall partition is provided which includes a plurality of spaced-apart, slidable and heightwise adjustable upstanding vertical supports and a plurality of horizontally-extending lateral supports, each of which is pivotably supported at its ends between a pair of adjacent vertical supports to permit a width adjustment of the wall partition. A filler material is wound on the lateral supports and is unwound therefrom to serve as wall panels for the wall partition. The wall partition has an extremely light weight and high degree of stability. It easily accommodates a wide range of room dimensions while affording a highly effective seal with the floor, ceiling, and walls of the room in which it is installed.

Abstract: A device for cleaning shoe soles, which can be stepped over, includes a grid with cylindrical rings having engaged surfaces and forming circular passages through the grid. A frame encloses these rings and has vertical pins extending through the axes of the rings. The cleaning brushes are plate-like and ring shaped and are rotatable upon these pins. The brushes extend into the circular passages of the grid. The pins also carry upper round plates, whereby the plates and the rings constitute edge supports for the brushes.
